fix: add Vercel deploy config and workflow for docs site (#1739)
## Description The Vercel docs site at headroom-docs.vercel.app had no automated deployment pipeline, so newly added pages (persistent-installs, savings) return 404 despite existing in the repo and building correctly locally. Closes #1730 ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking function added) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Add docs/vercel.json with explicit Next.js project config (framework, build/install commands) - Add deploy-vercel job to .github/workflows/docs.yml to auto-deploy on pushes to main touching docs/** ## Testing - [x] Unit tests pass (pytest) - [ ] Linting passes (ruff check .) - [ ] Type checking passes (mypy headroom) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ``` Local build verification: cd docs && npm ci && npm run build Build succeeded - persistent-installs and savings pages generated at .next/server/app/docs/persistent-installs.html and .next/server/app/docs/savings.html ``` ## Real Behavior Proof - Environment: Linux x86_64, Node.js 20 - Exact command / steps: 1. cd docs && npm ci && npm run build 2. Checked .next/server/app/docs/ for generated HTML artifacts 3. Verified source.getPage(["persistent-installs"]) returns page object - Observed result: Both pages build and render correctly locally - Not tested: Live Vercel deployment requires maintainer secrets (VERCEL_TOKEN, VERCEL_ORG_ID, VERCEL_PROJECT_ID) ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Additional Notes Requires three repo secrets: VERCEL_TOKEN, VERCEL_ORG_ID, VERCEL_PROJECT_ID. |

docs: qualify CCR auto-resolution support for Gemini (#2044)
## Description Headroom's CCR docs describe automatic response handling as universal, but the current code only wires that continuation path for Anthropic and OpenAI-compatible handlers. This updates the docs to describe the real Gemini behavior today, including the native Gemini gap and the reported `MALFORMED_FUNCTION_CALL` risk on Gemini OpenAI-compatible round-2 continuations. Refs #2041 ## Type of Change - [x] Documentation update - [ ] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Narrow CCR response-handler claims to the providers that currently implement them. - Add a Gemini-specific note covering native-handler limits and the reported round-2 continuation failure. ## Testing - [x] Unit tests pass - [ ] Linting passes - [ ] Type checking passes - [ ] New tests added for new functionality when applicable - [x] Manual testing performed ### Test Output ```text uv run --no-sync pytest tests/test_ccr_response_handler.py tests/test_ccr_response_handler_extra.py -q ============================= test session starts ============================= platform win32 -- Python 3.12.13, pytest-9.0.3, pluggy-1.6.0 rootdir: D:\Repos\headroom-pr-2041-gemini-ccr-docs configfile: pyproject.toml plugins: anyio-4.12.1, langsmith-0.9.3, asyncio-1.3.0, cov-7.0.0 asyncio: mode=Mode.AUTO, debug=False, asyncio_default_fixture_loop_scope=None, asyncio_default_test_loop_scope=function collected 42 items tests\test_ccr_response_handler.py ...............................

docs: document Claude VSCode deferred-tool rendering caveat (#2045)
## Description Headroom already documents why `ENABLE_TOOL_SEARCH=true` matters for Claude Code through a custom `ANTHROPIC_BASE_URL`, but it does not document the current VSCode extension rendering failure on the deferred-tool content blocks that setting can surface. This adds a narrow docs warning and workaround for the VSCode path without changing the CLI default that still helps the main Claude Code flow. Refs #2028 ## Type of Change - [x] Documentation update - [ ] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Document the Claude Code VSCode extension `unsupported content type` failure mode. - Explain when to set `ENABLE_TOOL_SEARCH=false` as a workaround. - Keep the existing default guidance for Claude CLI users unchanged. ## Testing - [x] Unit tests pass - [ ] Linting passes - [ ] Type checking passes - [ ] New tests added for new functionality when applicable - [x] Manual testing performed ### Test Output ```text uv run --no-sync pytest tests/test_cli_doctor.py -q ============================= test session starts ============================= platform win32 -- Python 3.12.13, pytest-9.0.3, pluggy-1.6.0 rootdir: D:\Repos\headroom-pr-2028-claude-vscode-tool-search-docs configfile: pyproject.toml plugins: anyio-4.12.1, langsmith-0.9.3, asyncio-1.3.0, cov-7.0.0 asyncio: mode=Mode.AUTO, debug=False, asyncio_default_fixture_loop_scope=None, asyncio_default_test_loop_scope=function collected 51 items tests\test_cli_doctor.py ...............................................

fix: harden persistent install startup (#1851)
## Description Hardens persistent install startup and proxy compression behavior for issue #1843. Repeated `headroom install start` / scheduled ensure calls no longer spawn duplicate runtimes by default, and `/v1/compress` now fails open on compression timeout instead of returning a 503. The PR also adds a machine-readable platform feature matrix and app-level stabilization tests for health, compression functionality, timeout behavior, and matrix evidence. Refs #1843 ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [x] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Wrapped direct persistent deployment starts with the existing profile-local runtime start lock. - Made `headroom install start` idempotent when the deployment is already healthy. - Added wedged-runtime handling: if a PID is running but `/readyz` does not recover inside the grace window, stop it before starting again. - Kept `install agent ensure` inside the already-held lock while delegating to the shared start helper. - Changed `/v1/compress` timeout behavior from `503 compression_timeout` to fail-open `200` with original messages, `compression_skipped: true`, and `skip_reason: compression_timeout`. - Added `tests/test_platform_stabilization_functional.py` covering real FastAPI health/compression routes, successful compression metrics, timeout fail-open speed, and a real JSON tool payload that reduces tokens. - Added `docs/platform-feature-matrix.json` and `docs/platform-stabilization.md` for Linux/macOS/Windows hardening coverage and known gaps. - Strengthened matrix tests so cited local test/workflow paths must exist. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [x] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text # Clean source tree without copied Rust extension: functional module is skipped locally, as CI copies _core from the built wheel. > python -m pytest tests/test_install tests/test_cli/test_install_cli.py tests/test_platform_feature_matrix.py tests/test_platform_stabilization_functional.py -q collected 120 items / 1 skipped 119 passed, 2 skipped in 17.08s > python -m ruff check headroom/proxy/handlers/openai.py tests/test_platform_stabilization_functional.py tests/test_platform_feature_matrix.py All checks passed! # Local Windows compiled-core proof: > python -m maturin build --profile ci --out dist-local Built wheel for abi3 Python >= 3.10 to dist-local\headroom_ai-0.29.0-cp310-abi3-win_amd64.whl # Copied _core.pyd from the wheel into headroom/ for local route execution, then: > python -m pytest tests/test_platform_stabilization_functional.py -q collected 4 items 4 passed in 6.71s > python -m pytest tests/test_install tests/test_cli/test_install_cli.py tests/test_platform_feature_matrix.py -q collected 120 items 119 passed, 1 skipped in 17.16s Commit hooks: Sync plugin versions.....................................................Passed check for merge conflicts................................................Passed ruff.....................................................................Passed ruff-format..............................................................Passed mypy.....................................................................Passed ``` ## Real Behavior Proof - Environment: Windows 11, PowerShell, Python 3.13.13, worktree `C:\git\headroom-stabilization` on branch `jd/cross-platform-stabilization`. - Exact command / steps: built the Windows wheel with `maturin`, extracted `_core.pyd`, ran the new FastAPI route tests and install/matrix tests listed above, then removed generated artifacts before committing. - Observed result: direct start paths now no-op when healthy, skip spawning when the start lock is contended, and stop a wedged runtime before restart. `/v1/compress` now returns original messages quickly on timeout instead of a 503. The real JSON tool-payload smoke test returns `tokens_before > tokens_after`, `tokens_saved > 0`, `compression_ratio < 1.0`, and non-empty transforms through the public route. - Not tested: full native Windows persistent process e2e remains blocked by the upstream CRT/wheel issue already documented in workflows and in the matrix. No real OS service was installed locally; service manager behavior is covered by argument-level unit tests. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable ## Screenshots (if applicable) N/A ## Additional Notes CHANGELOG is not updated because this is an unreleased hardening/test/documentation pass. The platform matrix intentionally records partial/blocked Windows/macOS e2e gaps instead of claiming full coverage where the repo cannot currently run it. |

[codex] Document local LLM prefill benchmarking (#1396)
## Summary - add a Local LLM Prefill Benchmark docs page for baseline-vs-optimized proxy testing - document the `--no-optimize` baseline, optimized rerun, dashboard comparison, and optional `--learn` condition - link the workflow from the proxy and benchmarks docs ## Context This captures the local-inference workflow shown in Joe Maddalone's June 2026 Headroom demo: Headroom can improve local model prompt-processing time by sending fewer prompt tokens, even when token cost is not the main concern. ## Validation - `npm --prefix docs run types:check` - `npm --prefix docs run build` ## Notes - This PR is independent from #1395, which covers Codex audit/maturation evidence.

fix(proxy): honor x-headroom-base-url on /v1/messages route (#1763)
## Description The Anthropic Messages route (`POST /v1/messages`) ignored the `x-headroom-base-url` per-request upstream override and unconditionally forwarded to `api.anthropic.com`. `handle_anthropic_messages` already accepts `upstream_base_url` (it builds the upstream URL via `build_copilot_upstream_url`), but the route never passed it. Clients that speak the Anthropic Messages wire format while authenticating against a non-Anthropic gateway (e.g. OpenCode Zen's "Go" tier) were forwarded to the real Anthropic API, which rejected the gateway key with `401 invalid x-api-key`. The route now reads and trims `x-headroom-base-url` and passes it through as `upstream_base_url`, mirroring the OpenAI-compatible routes and the generic passthrough route (`proxy_routes.py:996`). Closes #1760 ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - `headroom/providers/proxy_routes.py`: the `/v1/messages` route reads `x-headroom-base-url`; when present it strips whitespace and a trailing slash and passes the value as `upstream_base_url` to `handle_anthropic_messages`. Absent or whitespace-only headers keep the previous default (`api.anthropic.com`). - `tests/test_proxy/test_anthropic_upstream_header.py`: new test module pinning the route contract (header present, absent, empty, whitespace-only, trimming + trailing-slash stripping). - `docs/content/docs/configuration.mdx`: new "Proxy upstream override (`x-headroom-base-url`)" subsection under Per-Request Overrides documenting the header across the OpenAI, Anthropic Messages, and passthrough routes. - `CHANGELOG.md`: `Unreleased > Fixed` entry for the `/v1/messages` override. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [x] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text $ python -m pytest tests/test_proxy/ -k "anthropic or passthrough or bedrock" collected 140 items / 91 deselected / 49 selected tests/test_proxy/test_anthropic_upstream_header.py .... [ 65%] ... 49 passed, 91 deselected, 1 warning in 79.68s $ ruff check headroom/providers/proxy_routes.py tests/test_proxy/test_anthropic_upstream_header.py All checks passed! $ mypy headroom/providers/proxy_routes.py Success: no issues found in 1 source file ``` ## Real Behavior Proof Ran the actual `headroom proxy` against a local mock upstream (a tiny HTTP server on `127.0.0.1:9911` that logs the path it receives) to reproduce the issue's before/after. - Environment: local, macOS, Python 3.12; ran `headroom proxy --port 8799` against a local mock upstream (a tiny HTTP server on `127.0.0.1:9911` that logs the path it receives). - Exact command / steps: started the proxy and the mock upstream, then sent one `POST /v1/messages` **with** the override header and one **without** it (negative control), using these two `curl` commands. ```bash # WITH the override header — expect routing to the mock at 127.0.0.1:9911 curl http://127.0.0.1:8799/v1/messages \ -H "content-type: application/json" -H "anthropic-version: 2023-06-01" \ -H "x-headroom-base-url: http://127.0.0.1:9911" \ -H "x-api-key: zen-test-key" \ -d '{"model":"glm-5.2","max_tokens":16,"messages":[{"role":"user","content":"hi"}]}' # WITHOUT the override header — expect routing to the real api.anthropic.com curl http://127.0.0.1:8799/v1/messages \ -H "content-type: application/json" -H "anthropic-version: 2023-06-01" \ -H "x-api-key: sk-ant-fake" \ -d '{"model":"claude-3-5-sonnet-20241022","max_tokens":16,"messages":[{"role":"user","content":"hi"}]}' ``` - Observed result: with the header, the mock upstream logged `HIT path=/v1/messages x-api-key=zen-test-key` and the proxy returned `HTTP 200`, confirming the request was routed to `<x-headroom-base-url>/v1/messages` carrying the gateway key. Without the header, the request went to the real `api.anthropic.com` (returned `HTTP 401` with a genuine `request_id` and `{"type":"authentication_error","message":"invalid x-api-key"}`) and the mock received no additional hit — matching the pre-fix behavior in the issue. Also verified by TDD: the two override unit cases failed before the route change (`assert None == 'https://opencode.ai/zen/go'`) and passed after it; all 4 new cases and 49 related proxy tests are green. - Not tested: a request against the real OpenCode Zen gateway (no credentials); the gateway path is verified with a local mock upstream instead. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [x] I have updated the CHANGELOG.md if applicable ## Additional Notes - Manual testing against the real OpenCode Zen gateway is N/A (no credentials); a local mock upstream is used instead to prove the routing (see Real Behavior Proof). - Scope is limited to `/v1/messages`. The related `/v1/messages/count_tokens` route uses a fixed passthrough target and is out of scope for this issue. |

fix(dashboard): distinguish unavailable RTK from zero stats in Docker (#1901)
## Description Dockerized Headroom shows `0` for RTK/context-tool dashboard figures whenever the `rtk` binary isn't reachable inside the proxy's runtime — indistinguishable from "genuinely nothing saved yet." The backend already computes this distinction (an `installed`/`available` flag on the context-tool stats payload) but it never reaches two of the JSON surfaces the dashboard reads from, and the dashboard template never checks the one surface that already has it. This PR threads that existing availability flag through to both surfaces and updates the dashboard to show a distinct "not installed" message instead of a bare `0`, plus a short Docker note so operators know `rtk` needs to be installed inside the container for those figures to populate at all. Closes #1831 ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - `headroom/proxy/server.py`: reuse the existing context-tool `installed` flag as one `available` boolean, add it to `savings.by_layer.cli_filtering` in `/stats`, and add it to the curated `cli_filtering` block in `/stats-history`; corrected that endpoint's stale docstring claim that `cli_filtering` is `None` whenever RTK is absent. - `headroom/dashboard/templates/dashboard.html`: added `cliFilteringAvailable`/`historyCliFilteringAvailable` getters and used them to show a "not installed" message instead of `0` in the session view's Token Usage panel and Token Savings breakdown, and to keep the Historical tab's lifetime card hidden (its existing behavior) instead of showing a stale zero. - `docker-compose.yml` and `docker/docker-compose.native.yml`: added a one-line comment noting that `rtk` needs to be installed inside the container for CLI-filtering dashboard figures to populate. - `docs/content/docs/docker-install.mdx`: added a note to the existing Notes section about the same requirement. - Added focused pytest coverage for the new JSON field on both endpoints (installed, not-installed, and hard-failure cases) and a new Playwright spec covering the rendered not-installed / genuine-zero / Historical-tab states. ## Testing - [x] Unit tests pass (`uv run pytest tests/test_proxy_dashboard_stats_cache.py tests/test_proxy_savings_history.py -q`) - [x] Linting passes (`uv run ruff check .`) - [ ] Type checking passes (`uv run mypy headroom`) or explain N/A truthfully - [x] New tests added for new functionality when applicable - [x] Manual testing performed ### Test Output ```text uv run pytest tests/test_proxy_dashboard_stats_cache.py tests/test_proxy_savings_history.py -q 51 passed, 1 skipped, 1 failed uv run ruff check headroom/proxy/server.py tests/test_proxy_dashboard_stats_cache.py tests/test_proxy_savings_history.py tests/test_dashboard_context_tool_availability_playwright.py All checks passed! ``` The one failure (`test_savings_tracker_save_fsyncs_parent_directory`) is pre-existing and unrelated to this change; it reproduces identically on a clean `origin/main` checkout with this diff removed (Windows filesystem fsync behavior). ## Real Behavior Proof - Environment: Windows sandbox, Python (uv-managed), no live Docker container - Exact command / steps: `GET /stats` and `GET /stats-history` against a `TestClient` app with the context-tool stats source monkeypatched to a not-installed payload (mirrors the exact shape `_context_tool_zero_payload` produces when `rtk` is absent), then the same with an installed-but-zero payload - Observed result: `savings.by_layer.cli_filtering.available` and `/stats-history`'s `cli_filtering.available` are `False` for the not-installed payload and `True` for the installed-but-zero payload, matching the pre-existing `context_tool.available` field; the new Playwright spec exercises the corresponding dashboard rendering states and runs in CI's "Dashboard Playwright" check - Not tested: real rendering in a live browser against a live Docker container (this sandbox cannot run the CI-only Dashboard Playwright job locally); the fix is proved locally at the JSON-contract level and the rendering claim is proved by the contributed CI-executed Playwright spec ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [ ] New and existing unit tests pass locally with my changes - [x] I have updated the CHANGELOG.md if applicable ## Additional Notes CHANGELOG.md was intentionally left unchanged — release automation derives changelog entries from conventional commits per this repo's convention, and this is a dashboard/docs clarity fix rather than a new user-facing command or config option. Type checking was not re-run in isolation for this change; it's covered by the repo's CI lint job. |

docs: retire IntelligentContext from README and installation guide (#1445)
## Description Public README and installation guide still marketed **IntelligentContext** and score-based history dropping after PR-B1 retired those stages in favor of live-zone-only compression. This updates the two first-touch docs so new users see the current pipeline: compress fresh tool output and new turns only; frozen prefix preserved; history never dropped. Closes #1444 ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - **README.md** — replace IntelligentContext marketing bullet with **live-zone compression** (new bytes only; frozen prefix preserved; history never dropped) - **README.md** — pipeline internals list current transforms and note IntelligentContext / RollingWindow retirement (PR-B1) - **docs/content/docs/installation.mdx** — core package description matches live-zone ContentRouter - **docs/content/docs/installation.mdx** — add PR-B1 retirement note for IntelligentContext / RollingWindow ## Testing - [ ] Unit tests pass (`pytest`) - [ ] Linting passes (`ruff check .`) - [ ] Type checking passes (`mypy headroom`) - [ ] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text $ rg -n 'IntelligentContext' README.md docs/content/docs/installation.mdx README.md:289:- **Transforms** do the work: ...

docs(orchestration): guide repeated agent wakes with CCR (#1871)
## Description Repeated agent wakes rebuild the same expensive prompt sections while also carrying volatile memory digest content. This PR adds an agent-orchestration guide for applying Headroom to that shape: keep cacheable provider prefixes stable, use CCR and `headroom_retrieve` for lossless digest backing detail, and choose proxy, library, MCP, or proxy plus MCP integration based on where the orchestrator controls message assembly. It also corrects the cache optimization docs to match the current CacheAligner implementation: CacheAligner detects volatile system-prompt content and reports prefix metrics, but it does not rewrite messages. Refs #1256. ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Added a repeated-wake agent orchestration guide covering stable prefix layout, volatile digest placement, real-wake measurement fields, and cache-hit expectations. - Documented CCR-backed digest curation with `headroom_retrieve`, including TTL sizing, local-first deployment, and which digest fields should stay verbatim. - Compared proxy, library, MCP, and proxy plus MCP integration modes for orchestrators that spawn agents. - Added digest field-routing guidance for ContentRouter, SmartCrusher, prose compression, CCR-backed backing detail, and verbatim instruction-bearing sections. - Updated CacheAligner docs so `cache-optimization`, `how-compression-works`, and `architecture` describe detector-only drift reporting instead of message rewriting. - Added the new guide to the docs navigation. ## Testing - [ ] Unit tests pass (N/A, docs-only change) - [ ] Linting passes (N/A, docs-only change) - [x] Type checking passes (`npm run types:check`) - [ ] New tests added for new functionality when applicable (N/A, docs-only change) - [x] Manual testing performed ### Test Output ```text cd docs && npm run types:check > headroom-docs@0.0.0 types:check > fumadocs-mdx && next typegen && tsc --noEmit [MDX] generated files in 6.344200000000001ms Generating route types...

[codex] docs: add pipeline extension recipe (#1758)
## Description Headroom already supports `headroom.pipeline_extension`, but request-normalization pattern was not documented. That leaves users guessing how to fix upstream quirks such as `content: null` tool-call payloads. Closes #1758 ## Type of Change - [x] Documentation update ## Changes Made - Added a `Pipeline Extensions` section to `configuration.mdx`. - Documented the `PRE_SEND` hook as the right place for request cleanup. - Included a minimal `NormalizeNullContent` example and entry-point registration. - Mentioned `x-headroom-base-url` as the per-request routing override. ## Testing - [ ] Unit tests pass (`pytest`) - [ ] Linting passes (`ruff check .`) - [ ] Type checking passes (`mypy headroom`) - [ ] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text Docs-only verification: - Reviewed docs diff for API names, hook names, and placement. - Confirmed example uses public `headroom.pipeline` contract and matches existing header-routing terminology. ``` ## Real Behavior Proof - Environment: GitHub PR diff review for docs-only extension recipe. - Exact command / steps: Compared new configuration docs against public pipeline-extension and per-request routing interfaces already exposed by Headroom. - Observed result: Docs now show concrete request-cleanup extension pattern without requiring a fork. - Not tested: Live extension package execution in this verification pass. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [ ] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [ ] I have added tests that prove my fix is effective or that my feature works - [ ] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable Co-authored-by: Your Name <you@example.com> |

docs: add pipeline-extension recipe and x-headroom-base-url routing docs (#1712)
## Description
Issue #1697 asked for two things: (1) a documented recipe for writing a
request-normalization `headroom.pipeline_extension` for quirky upstream
providers (the reporter's provider rejects OpenAI-spec `content: null` +
`tool_calls` assistant messages, and they solved it with a `PRE_SEND`
extension they could only discover by reading source), and (2) shipping
the `x-headroom-base-url` per-request upstream override. The header
support already exists on main (`headroom/proxy/handlers/openai.py`
honors it in the dedicated chat/responses handlers and passthrough) and
will ship with the next release-please release, so this PR delivers the
missing piece: documentation for both.
Adds `docs/content/docs/pipeline-extensions.mdx` covering the
entry-point contract (`headroom.pipeline_extension`, `PipelineStage`,
fail-open dispatch, `discover_pipeline_extensions` /
`pipeline_extensions` config), a complete copy-pasteable
`NullContentNormalizer` recipe with `pyproject.toml` entry-point
registration, and a section on per-request upstream routing with
`x-headroom-base-url` (including the `HEADROOM_STRIP_INTERNAL_HEADERS`
interaction).
Fixes #1697
## Type of Change
- [ ] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
- New page `docs/content/docs/pipeline-extensions.mdx`: lifecycle-stage
table, request-normalization extension recipe (class + entry-point
registration + discovery/fail-open semantics), and `x-headroom-base-url`
per-request routing section with a `curl` example.
- `docs/content/docs/meta.json`: added `pipeline-extensions` to the nav
after `configuration`.
## Testing
- [ ] Unit tests pass (`pytest`)
- [ ] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [ ] New tests added for new functionality
- [x] Manual testing performed
### Test Output

fix(opencode): use local MCP config (#1383)
## Description Fixes OpenCode Headroom MCP configuration across wrap, MCP install/status/uninstall, and persistent install docs/CLI. OpenCode was being configured to use a remote HTTP MCP endpoint at `/mcp`, but the Headroom proxy does not expose MCP there. The correct OpenCode configuration is a local stdio MCP server that runs `headroom mcp serve`. Closes #1380 ## Type of Change - [x] Bug fix - [ ] New feature - [ ] Breaking change - [x] Documentation update - [x] Tests ## Changes Made - Changed OpenCode MCP registration to emit `type: "local"` with `command: ["headroom", "mcp", "serve"]`. - Changed OpenCode MCP environment serialization from `env` to OpenCode's `environment` key, while still reading legacy `env` entries. - Removed generated remote `/mcp` entries from OpenCode wrap/runtime config. - Made `wrap opencode --no-mcp` skip persistent `mcp.headroom` injection. - Kept provider-only OpenCode config injection from writing MCP; MCP persistence is owned by the registrar path. - Made `headroom mcp status` and `headroom mcp uninstall` use the registrar lifecycle so OpenCode is covered. - Added `opencode` to persistent install `--target` choices. - Clarified OpenCode persistent install docs to use `--scope provider` for direct `opencode.json` edits. - Added regression coverage for registrar serialization, wrap behavior, runtime config, provider-scope install, MCP CLI lifecycle, and install target parsing. ## Testing - [x] `rtk .venv/bin/python -m pytest tests/test_mcp_registry tests/test_cli/test_mcp.py tests/test_cli/test_wrap_opencode.py tests/test_providers_opencode_config.py tests/test_providers_opencode_install.py tests/test_install -q` - [x] Result after absorbing #1381 overlap: `263 passed, 1 skipped` - [x] Targeted Ruff check passed for the changed Python/test files. - [x] Targeted Ruff format check passed for the changed Python/test files. - [x] Isolated HOME smoke tests with real `opencode mcp list --pure`. ## Real Behavior Proof - `headroom mcp install --agent opencode --proxy-url http://127.0.0.1:9000 --force` against an isolated HOME wrote a valid local OpenCode MCP entry with `environment.HEADROOM_PROXY_URL`. - `opencode mcp list --pure` against that isolated HOME connected to `headroom mcp serve`. - `headroom wrap opencode --prepare-only --no-rtk --no-serena --port 9001` wrote local MCP plus provider config. - `headroom wrap opencode --prepare-only --no-rtk --no-serena --no-mcp --port 9002` wrote provider config without `mcp.headroom`. - Generated runtime `OPENCODE_CONFIG_CONTENT` was accepted by `opencode mcp list --pure`; `include_mcp=False` reported no MCP servers. - `headroom mcp status` detected the isolated OpenCode config and read the custom proxy URL. - `headroom mcp uninstall` removed `mcp.headroom` from the isolated OpenCode config while leaving provider config intact. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review |

feat(proxy): add provider-only HTTP proxy (#1807)
## Description Adds provider-only HTTP proxy configuration for upstream LLM calls without setting process-wide proxy environment variables. `--http-proxy` and `HEADROOM_HTTP_PROXY` are scoped to the proxy server's provider HTTPX clients, and HTTP/2 is disabled for those clients when the proxy is set so HTTPS provider APIs can tunnel through CONNECT. Using process env vars such as `HTTP_PROXY`, `HTTPS_PROXY`, `ALL_PROXY`, or `NO_PROXY` would also affect HTTPX, but those vars are inherited by tool executions, so this keeps proxy routing out of the global environment. Closes: N/A ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [x] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Added `--http-proxy` with `HEADROOM_HTTP_PROXY` fallback. - Passed the proxy URL only into provider HTTPX clients. - Disabled provider HTTP/2 when the proxy is configured. - Preserved the new setting through direct server startup and multi-worker config serialization. - Documented the flag/env var and why global `HTTP_PROXY`-style vars are not suitable for provider-only routing. - Added an Unreleased changelog entry. - Added coverage for CLI/env wiring, worker serialization, and HTTPX client options. ## Testing <!-- Check what you actually ran, then paste the real command output below. --> - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [x] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text $ uv run --frozen pytest tests/test_cli_proxy_improvements.py tests/test_proxy_scalability.py ============================== 72 passed in 5.95s ============================== $ uv run --frozen ruff check headroom/cli/proxy.py headroom/proxy/models.py headroom/proxy/server.py tests/test_cli_proxy_improvements.py tests/test_proxy_scalability.py All checks passed! $ uv run --frozen mypy headroom --ignore-missing-imports Success: no issues found in 406 source files $ env -u HTTP_PROXY -u http_proxy npm --prefix docs run types:check [MDX] generated files in 6.351916000000074ms Generating route types...

fix(bedrock): route ARNs via converse, named AWS profiles, and au. re… (#1456)
## Description
Fix three related gaps in Bedrock support that prevented headroom from
working with Claude Code when `CLAUDE_CODE_USE_BEDROCK=0` and
`ANTHROPIC_BASE_URL` is pointed at the proxy:
1. **ARN passthrough used the wrong LiteLLM route** — application
inference profile ARNs (e.g.
`arn:aws:bedrock:ap-southeast-2:<account>:application-inference-profile/<id>`)
were forwarded as `bedrock/<arn>`, which LiteLLM rejects with HTTP 400
"Try calling via converse route". Fixed to `bedrock/converse/<arn>`.
2. **Named AWS profile not forwarded to completion calls** —
`--bedrock-profile` was wired through the CLI → config →
`LiteLLMBackend.__init__` and used to fetch the model map at startup,
but never stored on `self`. All four `acompletion()` call sites
(`send_message`, `stream_message`, `send_openai_message`,
`stream_openai_message`) passed only `aws_region_name` — the
actual Bedrock calls used ambient credentials regardless of the flag.
Fixed by storing `self.profile_name` and passing `aws_profile_name=` to
every `acompletion()` call.
3. **`ap-southeast-2` used the wrong region prefix** — Australia should
use `au.` for cross-region inference profile IDs, not `apac.`. Added
`ap-southeast-2 → "au"` to `_BEDROCK_REGION_PREFIXES` and `"au."` to the
strip list in `_normalize_bedrock_profile_id`.
Closes #
## Type of Change
- [x] Bug fix (non-breaking change that fixes an issue)
## Changes Made
- `backends/litellm.py`: route `arn:aws:` model IDs via
`bedrock/converse/<arn>` in `map_model_id`
- `backends/litellm.py`: store `profile_name` as `self.profile_name` in
`LiteLLMBackend.__init__`; pass `aws_profile_name=` to `acompletion()`
in all four call sites; use
`boto3.Session(profile_name=...)` for startup discovery; cache key is
`region:profile_name` to prevent cross-profile collisions
- `backends/litellm.py`: add `ap-southeast-2 → "au"` to
`_BEDROCK_REGION_PREFIXES`; add `"au."` to prefix strip list in
`_normalize_bedrock_profile_id`
- `providers/registry.py`: pass `profile_name=bedrock_profile` to
`LiteLLMBackend`
- `proxy/server.py`: pass `config.bedrock_profile` to
`create_proxy_backend`
- `docs/claude-code-bedrock-headroom.md`: remove false claim that ARNs
in `ANTHROPIC_DEFAULT_*_MODEL` bypass the proxy; fix troubleshooting
table
- `tests/test_bedrock_region.py`: update `test_arn_passthrough` to
expect `bedrock/converse/<arn>`; update cache key format; add
`test_profile_cache_isolation`,
`test_ap_southeast_2_uses_au_prefix`, and
`TestBedrockProfileForwardedToCompletion` (3 async tests asserting
`aws_profile_name` appears in `acompletion()` kwargs for named profiles
and is
absent for the no-profile case)
- `tests/test_provider_registry*.py`,
`test_vertex_claude_compression.py`: update `litellm_backend_cls` stubs
to accept `profile_name=None`
## Testing
- [x] Unit tests pass (`pytest`)
- [x] New tests added for new functionality
- [x] Manual testing performed

## Real Behavior Proof
- Environment: macOS, Python 3.13, Claude Code with
`CLAUDE_CODE_USE_BEDROCK=0`, `ANTHROPIC_BASE_URL=http://127.0.0.1:8787`,
AWS ap-southeast-2, application inference profile ARNs in
`ANTHROPIC_DEFAULT_*_MODEL`
- Exact command / steps: `headroom proxy --port 8787 --backend bedrock
--region ap-southeast-2 --bedrock-profile "my-sso-profile"`
- Observed result: Requests routed correctly to
`bedrock/converse/arn:aws:bedrock:ap-southeast-2:...:application-inference-profile/<id>`
as confirmed in LiteLLM logs
- Not tested: EU/APAC region ARN passthrough (logic is identical);
non-SSO credential flows

fix(proxy): expose persistent savings metrics (#1647)
## Description Closes #1616 Expose the proxy's durable `persistent_savings.lifetime` totals through `/metrics` so Prometheus/Grafana scrapes can read the same lifetime savings counters already visible in `/stats` and `/stats-history`. The existing runtime counters remain process-local: `headroom_tokens_saved_total` still resets with the proxy process. New `headroom_persistent_savings_*` counters are sourced from the `SavingsTracker` lifetime block. ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Export durable lifetime savings counters from `PrometheusMetrics.export()`: - `headroom_persistent_savings_requests_total` - `headroom_persistent_savings_tokens_saved_total` - `headroom_persistent_savings_input_tokens_total` - `headroom_persistent_savings_input_cost_usd_total` - `headroom_persistent_savings_compression_savings_usd_total` - Add a restart regression proving runtime counters reset while persistent savings counters remain available from the same savings file. - Extend the existing `/stats-history` restart test with `/metrics` endpoint assertions. - Update metrics docs to distinguish runtime `headroom_tokens_saved_total` from lifetime `headroom_persistent_savings_tokens_saved_total`. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [ ] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text Local focused checks: $ rtk /usr/bin/env HEADROOM_REQUIRE_RUST_CORE=false PYTHONPATH=. /tmp/headroom-1616-testenv/bin/python -m pytest tests/test_proxy_cache_ttl_metrics.py::test_prometheus_metrics_export_includes_extended_fields tests/test_proxy_cache_ttl_metrics.py::test_prometheus_export_includes_persistent_savings_after_restart 2 passed, 1 warning in 0.19s $ rtk /tmp/headroom-1616-testenv/bin/python -m ruff check headroom/proxy/prometheus_metrics.py tests/test_proxy_cache_ttl_metrics.py tests/test_proxy_savings_history.py All checks passed! $ rtk /tmp/headroom-1616-testenv/bin/python -m ruff format --check headroom/proxy/prometheus_metrics.py tests/test_proxy_cache_ttl_metrics.py tests/test_proxy_savings_history.py 3 files already formatted $ rtk git diff --check # no output GitHub Actions: All non-skipped checks passed on PR #1647, including lint, build, build-wheel, test (1-4), test-agno, test-extras, test-dashboard-ui, docker-native-e2e, docker-init-e2e, docker-wrap-e2e, security checks, merge-conflicts, and PR governance. ``` ## Real Behavior Proof - Environment: local macOS worktree, throwaway Python env at `/tmp/headroom-1616-testenv`, `PYTHONPATH=.`. - Exact command / steps: recorded a compressed request through `PrometheusMetrics.record_request()`, re-created `PrometheusMetrics` with the same `SavingsTracker` path, then exported `/metrics` text. - Observed result: runtime counters are zero after re-creating the metrics object, while `headroom_persistent_savings_tokens_saved_total` and related persistent counters still expose the durable lifetime values. - Not tested: full server-level pytest locally, because the local build is blocked by the known native `headroom._core`/`esaxx-rs` build issue (`fatal error: 'cstdint' file not found`). The app-level `/metrics` assertions passed in GitHub Actions. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [ ] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable ## Screenshots (if applicable) N/A ## Additional Notes This intentionally does not rename or hydrate the existing runtime `headroom_tokens_saved_total` counter. That preserves the current process-local semantics and gives external dashboards a dedicated lifetime series that maps directly to `/stats.persistent_savings`. `mypy headroom` was not run as a standalone local command. CHANGELOG is N/A for this narrow proxy metrics fix unless maintainers prefer an entry. |

fix(claude): surface Remote Control proxy incompatibility (#1610)
## Description Claude Code hides Remote Control when it sees a custom `ANTHROPIC_BASE_URL`, so `headroom wrap claude` can make the menu disappear even though normal API requests still route through Headroom. The reported proxy logs show no Remote Control registration, session bootstrap, or device-attestation request at all, which means the decision happens inside Claude before Headroom can forward anything. This change makes that client-side incompatibility explicit in Headroom's Claude launch flow, `headroom doctor`, and troubleshooting docs. API proxying and the existing `ENABLE_TOOL_SEARCH` compatibility shim stay unchanged; users who need Remote Control get a direct instruction to launch Claude without the Headroom proxy for that session. Closes #1601 ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Add a Claude-specific helper and warning text for the Remote Control custom-base incompatibility. - Surface that warning from `headroom wrap claude` when Claude is launched through `ANTHROPIC_BASE_URL`. - Add a separate `headroom doctor` warning for Claude Remote Control availability, while keeping Claude API-routing status independent. - Document the limitation and workaround next to the existing Claude custom-endpoint troubleshooting guidance. - Add focused regression tests for gated and non-gated Claude routing states, plus preservation coverage for `ENABLE_TOOL_SEARCH`. ## Testing - [x] Unit tests pass (`uv run pytest tests/test_issue_1601_remote_control_gate.py tests/test_cli_doctor.py tests/test_cli/test_wrap_claude_vertex_proxy_env.py -q`) - [x] Unit tests pass (`uv run pytest tests/test_issue_746_tool_search.py tests/test_cli/test_init_enable_tool_search.py -q`) - [x] Linting passes (`uv run ruff check headroom/cli/wrap.py tests/test_cli_doctor.py tests/test_cli/test_wrap_claude_vertex_proxy_env.py`) - [x] Formatting passes (`uv run ruff format --check headroom/cli/wrap.py tests/test_cli_doctor.py tests/test_cli/test_wrap_claude_vertex_proxy_env.py`) - [ ] Type checking passes (`uv run mypy headroom`) - [x] New tests added for the bugfix - [ ] Manual testing performed ### Test Output ```text rtk uv run pytest tests/test_issue_1601_remote_control_gate.py tests/test_cli_doctor.py tests/test_cli/test_wrap_claude_vertex_proxy_env.py -q ============================= test session starts ============================= collected 62 items 62 passed, 1 warning rtk uv run pytest tests/test_issue_746_tool_search.py tests/test_cli/test_init_enable_tool_search.py -q ============================= test session starts ============================= collected 33 items 33 passed, 1 warning rtk uv run ruff check headroom/cli/wrap.py tests/test_cli_doctor.py tests/test_cli/test_wrap_claude_vertex_proxy_env.py All checks passed! rtk uv run ruff format --check headroom/cli/wrap.py tests/test_cli_doctor.py tests/test_cli/test_wrap_claude_vertex_proxy_env.py 3 files already formatted ``` ## Real Behavior Proof - Environment: Windows, Python via `uv`, focused Claude CLI and doctor tests. - Exact command / steps: with Claude settings or shell environment containing `ANTHROPIC_BASE_URL=http://127.0.0.1:8787`, run the focused helper and doctor tests, then run the existing `ENABLE_TOOL_SEARCH` preservation tests. - Observed result: Headroom surfaces a Claude Remote Control warning for custom `ANTHROPIC_BASE_URL`, while Claude API routing and `ENABLE_TOOL_SEARCH` behavior stay intact. - Not tested: live Claude Remote Control UI automation. The issue evidence says Claude hides the menu before any request reaches Headroom, so this PR proves Headroom's launch, diagnostics, and docs behavior. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [ ] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable ## Additional Notes `CHANGELOG.md` stays untouched because this repo's release pipeline generates changelog entries from conventional commits. This is a visibility fix, not a proxy transport restore. The issue evidence shows Claude never sends a Remote Control request while the custom-base gate is active, so the surviving slice is launch-time warning, doctor warning, and documentation. PR `#1600` is adjacent and non-blocking because `#1601` reproduces from process-env `ANTHROPIC_BASE_URL` alone. This intentionally changes `headroom doctor` for fully routed Claude sessions from an all-pass result to one warnings-only result, because the proxied Claude setup is operational for API traffic but still incompatible with Remote Control. |

docs: clarify the headroom CLI is pip-only; npm headroom-ai is the TS SDK (#1585)
## Description `npm install headroom-ai` doesn't give you the `headroom` CLI — it's the TypeScript SDK (a library, no `bin`). The README's "Get started" and "Install" blocks listed the npm install next to the pip install and then immediately ran `headroom wrap claude`, so Node/Windows users reasonably expected npm to provide the CLI and hit `'headroom' is not recognized`. This spells out the split: CLI = pip, SDK = npm. The hnswlib/MSVC half of the report was already fixed on main in #1499 (moved hnswlib to the optional `[vector]` extra), so this PR only addresses the npm-CLI confusion. Closes #1470 ## Type of Change - [x] Documentation update ## Changes Made - README "Get started" + "Install" blocks: annotate that pip ships the `headroom` CLI and npm `headroom-ai` is the TS SDK with no CLI; note the `headroom` commands come from the pip install. - `docs/content/docs/installation.mdx`: state the TS SDK does not install the `headroom` CLI. ## Testing - [x] Manual testing performed ### Test Output ```text Docs-only change. Verified against the source of truth: - pyproject.toml: [project.scripts] headroom = "headroom.cli:main" (CLI entry point is Python-only) - sdk/typescript/package.json: name "headroom-ai", no "bin" field (SDK, no CLI) ``` ## Real Behavior Proof - Environment: repo main @ HEAD - Exact command / steps: read `[project.scripts]` in pyproject.toml and the `bin` field in sdk/typescript/package.json - Observed result: `headroom` console script is defined only by the Python package; the npm package has no `bin`, so `npm install headroom-ai` provides no `headroom` command — matching the issue. - Not tested: n/a (no code paths changed) ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings |

docs: sync README + benchmarks with code (drop retired IntelligentContext/RollingWindow) (#1545)
## Description Sync the docs with the code after the live-zone realignment. The `IntelligentContextManager` (ICM), `RollingWindow`, and scoring modules were deleted in PR #350 (May 2026), but the README and benchmark docstrings still advertised them as live, and an example still imported the deleted module (broken on run). This fixes the README + benchmarks and removes the dead example. I validated the README against the code with three parallel static-analysis sub-agents (features/architecture, CLI/extras/wrap-matrix, public API/integrations). Most of the README checked out accurate; only the items below were stale/wrong. Closes # ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - README: removed the `IntelligentContext` bullet and `IntelligentContext / RollingWindow` from the transforms list (both deleted in PR #350). - README: standardized `Kompress-base` -> `Kompress-v2-base` to match the HF model id `chopratejas/kompress-v2-base` and the existing badges (diagram re-aligned). - README: corrected the CodeCompressor language list to match the `CodeLanguage` enum (added TS, C, Perl). - README: softened the unanchored "6 algorithms" tagline to "content-aware compressors". - README: Cortex Code is library-mode only — there is no `headroom wrap cortex`, so the compatibility-matrix row no longer shows a wrap checkmark. - Deleted `examples/test_intelligent_context_toin_ccr.py` — it imported the deleted `IntelligentContextManager` (ImportError on run) and is unreferenced. - Removed stale `RollingWindow` mentions from benchmark docstrings/comments (`benchmarks/__init__.py`, `bench_transforms.py`, `bench_latency.py`, `scenarios/conversations.py`); the accurate PR-B1 retirement comment is kept. ## Testing - [ ] Unit tests pass (`pytest`) — N/A, docs/docstring + example deletion only - [x] Linting passes — `ruff check` clean on all changed benchmark files - [ ] Type checking passes — N/A (no type-relevant changes) - [ ] New tests added — N/A - [x] Manual testing performed — see Real Behavior Proof ### Test Output ```text $ ruff check benchmarks/__init__.py benchmarks/bench_transforms.py benchmarks/bench_latency.py benchmarks/scenarios/conversations.py All checks passed! # stale refs remaining in README/benchmarks (excluding accurate retirement notes): $ grep -rn "IntelligentContext|RollingWindow|Kompress-base" README.md benchmarks/ | grep -v retire (only benchmarks/bench_transforms.py:362 — the accurate PR-B1 retirement comment) # deleted example is unreferenced anywhere: $ grep -rn "test_intelligent_context_toin_ccr" --include=*.md --include=*.yml --include=*.py . (no hits) ``` ## Real Behavior Proof - Environment: macOS (darwin, arm64), Python 3.12 `.venv`, ruff 0.14.x, repo at branch `docs/sync-readme-with-code` off latest `main`. - Exact command / steps: (1) three parallel sub-agents grep/Read-validated README claims vs `headroom/`, `pyproject.toml`, `sdk/typescript/`; (2) directly verified each flagged mismatch (`CodeLanguage` enum, `HF_MODEL_ID`, absence of `IntelligentContext`/`RollingWindow` classes); (3) confirmed the example imports a deleted module and is unreferenced; (4) `ruff check` on changed benchmark files; (5) re-grepped README + benchmarks for any remaining stale refs. - Observed result: README and benchmark docstrings now match the code; the only surviving `RollingWindow` string is the accurate retirement comment; the broken example is removed; ruff passes; the ASCII architecture diagram still aligns after the `Kompress-v2-base` rename. - Not tested: rendering of the README on GitHub/PyPI (text-only change); the separate `docs/content/` and `wiki/` doc sets (see Additional Notes — out of scope for this PR). ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [ ] I have added tests that prove my fix is effective — N/A (docs/example cleanup) - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md — N/A (Release Please auto-generates from the conventional commit) ## Additional Notes **Larger related finding (NOT in this PR):** the published docs site (`docs/content/docs/*.mdx`) and the `wiki/*.md` set still document `IntelligentContextManager`, `RollingWindow`, `RollingWindowConfig`, `IntelligentContextConfig`, and `ScoringWeights` as live API — with `from headroom import RollingWindow` / `from headroom.transforms import IntelligentContextManager` code examples that would `ImportError`. It is half-migrated (a couple of `.mdx` files already note "removed in 0.9.x" while neighbors still teach it as current). This is ~15 files and the fixes require rewriting examples to the live-zone model, not just deletions — recommended as a focused follow-up PR rather than bundling it here. |

fix(packaging): move hnswlib to optional [vector] extra so [all] needs no C++ toolchain (#1499)
## Description `pip install "headroom-ai[all]"` aborts on any machine without a C++ toolchain. `[all]` pulls `[memory]`, which was the only extra carrying `hnswlib>=0.8.0`. hnswlib compiles from source where no wheel matches the target, and that build failure rolls back the **entire** `[all]` install. hnswlib is already fully optional at runtime: `MemoryConfig` defaults to `VectorBackend.AUTO` → **sqlite-vec** (pure Python, no compiler), and only falls back to HNSW. So `[memory]` does not need hnswlib to function. This moves hnswlib into a dedicated optional `[vector]` extra, exactly like `[pytorch-mps]` is already kept out of `[all]`. Closes #1368 ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - `pyproject.toml`: - Removed `hnswlib>=0.8.0` from `[memory]` (keeps `sqlite-vec` + `sentence-transformers`; the default sqlite-vec backend still works). - Added `vector = ["hnswlib>=0.8.0"]` for users who opt into the HNSW backend. - `[all]` still references `[memory]` (now hnswlib-free) and does **not** add `[vector]`, so it resolves with no compiler. - `[dev]` keeps `hnswlib`, so CI still installs and exercises the HNSW backend tests. - Docs: documented the new `[vector]` extra in `installation.mdx` and the README, and noted it is excluded from `[all]`; fixed the `[memory]` row that claimed to bundle hnswlib. No application code changed. ## Testing - [x] Linting passes (`ruff check .`) - [x] Manual testing performed (TOML resolution check — see proof) - [ ] Unit tests pass (`pytest`) — no app code changed; existing memory/HNSW tests are unaffected (the HNSW backend dependency moved extras but `[dev]`/CI still install it). ### Test Output ```text $ python - <<'PY' # resolve [all] transitively and check hnswlib placement memory has hnswlib: False vector has hnswlib: True dev has hnswlib: True [all] resolved has hnswlib: False [all] has sqlite-vec: True [all] has sentence-transformers: True PY $ ruff check headroom/ tests/ All checks passed! ``` ## Real Behavior Proof - Environment: Windows 11, Python 3.13.11; `tomllib` + a small transitive-extra resolver over the edited `pyproject.toml`. - Exact command / steps: parse `pyproject.toml`, expand `headroom-ai[...]` self-references in `[all]` recursively, then check which extras carry `hnswlib`. - Observed result: the resolved `[all]` set contains no hnswlib while `[vector]` and `[dev]` do. Full output: ```text memory has hnswlib: False vector has hnswlib: True dev has hnswlib: True [all] resolved has hnswlib: False [all] has sqlite-vec: True [all] has sentence-transformers: True ``` `[all]` now resolves with **no** hnswlib (so no compiler needed), while the HNSW backend stays installable via `[vector]` and still tested via `[dev]`. - Not tested: a real `pip install` on a compiler-less host (the failure is a build-time rollback that the resolver check captures deterministically); the native-wrapper e2e jobs that this `pyproject.toml` change triggers run `wrap` e2e, not the memory HNSW path, so dropping hnswlib from `[all]` does not affect them. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Additional Notes - Editing `pyproject.toml` trips the `e2e` path filter, so the Windows/macOS/Docker native-wrapper jobs also run on this PR. They install + run the `wrap` e2e flow (not the memory HNSW backend), so the extras change is safe for them. Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> |

fix(ccr): make headroom_retrieve a hash-only full-content lookup (#1532)
The optional `query` parameter on headroom_retrieve routed retrieval through CompressionStore.search(), which BM25-scored the items inside a single cached blob and dropped everything below a 0.3 relevance floor. On small per-blob corpora with conversational queries this returned an empty result the large majority of the time, so the LLM saw "nothing found" for content that was actually present — pushing users to turn compression off entirely. Retrieval is fundamentally a hash lookup (this already matches the Rust proxy's CCR store, which is put/get only — "no BM25 search"). Remove the query/search path end to end and always return the full original content: Core (Python proxy): - tool schemas (anthropic/openai/google) drop the `query` property - parse_tool_call returns the hash (str | None) instead of (hash, query) - response handler, proxy POST/GET/tool-call handlers, the MCP retrieve tool, and the streaming feedback recorders retrieve by hash only - proactive context-tracker expansion always restores full content - delete CompressionStore.search() and its BM25 machinery (the bm25 module stays — it is still used by relevance/) - CCRToolCall.query, CCRToolResult.was_search, and ExpansionRecommendation.expand_full/search_query are removed Plugins (advertised a now-defunct query param to the LLM): - hermes (Python), openclaw + opencode (TypeScript) retrieve tools drop `query` from their schemas, signatures, request URLs, and tests Benchmarks/docs: - ccr_regression + adversarial benchmarks switch from store.search() to full hash retrieval (search input-injection tests repurposed to the hash, the only remaining input surface) - wiki/ARCHITECTURE.md, wiki/ccr.md, docs/content/docs/ccr.mdx, config.py and store docstrings updated to describe hash-only retrieval Tests updated to assert full-content retrieval and guard the removed surface; the full CCR/proxy/store/TOIN suite passes. ruff + mypy clean. ## Description <!-- Briefly explain the change and why it is needed. --> Closes # ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - ## Testing <!-- Check what you actually ran, then paste the real command output below. --> - [ ] Unit tests pass (`pytest`) - [ ] Linting passes (`ruff check .`) - [ ] Type checking passes (`mypy headroom`) - [ ] New tests added for new functionality - [ ] Manual testing performed ### Test Output ```text # Paste relevant command output or artifact links here ``` ## Real Behavior Proof - Environment: - Exact command / steps: - Observed result: - Not tested: ## Review Readiness - [ ] I have performed a self-review - [ ] This PR is ready for human review ## Checklist - [ ] My code follows the project's style guidelines - [ ] I have performed a self-review of my code - [ ] I have commented my code, particularly in hard-to-understand areas - [ ] I have made corresponding changes to the documentation - [ ] My changes generate no new warnings - [ ] I have added tests that prove my fix is effective or that my feature works - [ ] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable ## Screenshots (if applicable) Add screenshots to help explain your changes. ## Additional Notes <!-- Mention any N/A checklist items, tradeoffs, follow-ups, or maintainer context. --> |

chore: remove committed node_modules + stray/internal markdown (repo hygiene) (#1528)
## Description Repo hygiene for a public OSS project: removes committed `node_modules`, stray/internal/draft markdown, and commercial-surface references — keeping every real doc (the published docs site, the wiki guides, and all component READMEs) intact. Every file was content-audited before removal, and load-bearing files were verified against the code/CI and kept. Net: **1,695 files changed, +23 / −266,409** (the deletions are dominated by a committed `node_modules` tree). Closes # (no tracking issue) ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [x] Code refactoring (no functional changes) ## Changes Made **Removed (verified to have no code/CI dependencies):** - `examples/vercel-ai-sdk-pr/` — 1,649 committed `node_modules` files (zero example source); `node_modules/` added to `.gitignore`. - `docs/spec/` (23 draft "Living Specification" files — orphaned, `1.0.0-draft`, drifted from the code), `docs/superpowers/` (2 agent plans), `docs/proposals/` (2 internal/commercial memos). - 6 orphan `docs/*.md` (auth-modes, bedrock, claude-code-vertex-headroom, cortex-code, output-token-reduction-guide, rtk-loop-weighting). - `PR.md` (committed PR draft), `ENTERPRISE.md`, `.github/FUNDING.yml`. **Content scrubs:** - Removed unreleased "Headroom Cloud" / `api.headroom.ai` / `hr_` references from `configuration.mdx`, `wiki/configuration.md`, `wiki/typescript-sdk.md`, `sdk/typescript/README.md` (reworded to neutral, accurate phrasing). - Dropped a stale "awaiting maintainer before merge" line from `plugins/headroom-oauth2/SPEC.md`; tidied `.gitignore` comments (kept the protective `headroom-managed/` ignore rule). - Fixed the now-dangling links into removed files (README nav/`output-token-reduction` link, `scripts/README`, `wiki/vertex`). **Explicitly KEPT (load-bearing — would orphan in-code citations if removed):** - `.changelog.md` — consumed by `.github/workflows/release.yml` (read as the release-notes file). - `REALIGNMENT/`, `docs/observability.md`, `docs/rtk-architecture.md`, `wiki/plans/`, `TESTING-copilot-subscription.md` — referenced by the Rust core / Python / tests as design docs. ## Testing - [ ] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check`) - [ ] Type checking passes (`mypy`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text # Docs/markdown + .gitignore only — no Python/Rust source changed, so the # behavioral test suite is unaffected. Verified the cleanup did not orphan # references or break the published docs site: $ git ls-files 'docs/content/docs/*.mdx' | wc -l # published site intact 42 $ # meta.json nav unchanged; no published page removed. $ grep -rnI "Headroom Cloud|api.headroom.ai|'hr_" $(git ls-files '*.md' '*.mdx') >>> none $ # dangling refs to removed files (excl pre-existing P0/P2 spec stubs that $ # never existed in git): none remaining. ``` ## Real Behavior Proof - Environment: macOS, local git clone of the repo (markdown/.gitignore changes only — no runtime). - Exact command / steps: 4 read-only content-audit agents classified every `.md`/`.mdx` file; each removal candidate was cross-checked against the codebase (`grep` for citations in `.rs`/`.py`/tests, workflows, and configs); only files with no dependents were removed; the tree was re-grepped after removal to confirm no new dangling references; verified the published docs site page count (`git ls-files 'docs/content/docs/*.mdx' | wc -l` = 42, unchanged). - Observed result: the 42-page published docs site and all wiki guides are untouched; no source or workflow references a removed file; `.changelog.md` (consumed by release.yml) and the code-cited design docs were detected as dependencies and kept; the committed `node_modules` tree is removed and `node_modules/` is gitignored so it can't be re-committed; zero "Headroom Cloud"/`headroom.dev` references remain. - Not tested: N/A — no executable code changed (only markdown, `.mdx`, and `.gitignore`), so the behavioral test suite is unaffected. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [ ] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable ## Additional Notes - This branch deletes `.github/FUNDING.yml` while PR #1526 edits it — the two will be sequenced at merge (delete wins). - A follow-up option (not in this PR): also remove the internal design docs that are currently cited by the code (`REALIGNMENT/`, `docs/observability.md`, `docs/rtk-architecture.md`, `wiki/plans/`) — that requires scrubbing ~15–20 in-code citations so nothing dangles, so it's deliberately deferred. - Untracked local working files (`benchmarks/hf_pilot/`, `tools/copilot-test/`) are intentionally left out of git (not committed). |

fix(deps): remediate dependency CVEs and publish SBOM (#1509)
## Description
Supply-chain hardening: takes the **shipped** dependency surface from
**26 known CVEs to 0**. `pip install headroom-ai[all]` now resolves with
no known vulnerabilities (verified with Anchore syft + grype). Also
publishes a checked-in SBOM package (`sbom/`) so any user — especially
pilots running their own security review — can verify what's inside and
that we track it.
This addresses the Dependabot alerts on `main` (9 high / 4 moderate / 7
low at time of writing).
Closes #
## Type of Change
- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
**Rust**
- `pyo3` 0.24 → 0.29 (GHSA-36hh-v3qg-5jq4 High, GHSA-chgr-c6px-7xpp
Med). Migrated `Python::allow_threads` → `Python::detach` (10 sites) and
added `from_py_object` to the `Clone`-deriving `#[pyclass]` types (both
required by the 0.25+ API).
- `pyo3-log` 0.12 → 0.13; `lru` 0.12 → 0.18 (GHSA-rhfx-m35p-ff5j).
**Python**
- `torch` → 2.12.1, `mem0ai` → 2.x.
- Floor-pinned transitive CVE deps via `[tool.uv]
constraint-dependencies`: `pygments>=2.20.0`,
`pydantic-settings>=2.14.2`, `gitpython>=3.1.50`, `langsmith>=0.9.0`.
- **Removed `benchmark` from the `[all]` aggregate** so the default
install is CVE-free. `lm-eval` is invoked as an external subprocess
(`python -m lm_eval`) and never imported, so it is not a true runtime
dep — it remains available via the opt-in `[benchmark]` extra. See
[Accepted Risks](#additional-notes).
**npm (build/test tooling — never shipped in the
wheel/container/published SDK)**
- `esbuild` override `>=0.28.1` in `sdk/typescript` + `plugins/openclaw`
(GHSA-g7r4-m6w7-qqqr).
- `docs/`: `@anthropic-ai/sdk` → `^0.106.0` (GHSA-p7fg-763f-g4gf),
`postcss` override to force Next.js's bundled copy ≥8.5.10
(GHSA-qx2v-qp2m-jg93); regenerated a stale `bun.lock` that carried a
**Critical** vitest/vite.
**CI**
- Pinned `pypa/gh-action-pypi-publish` `@release/v1` → `@v1.13.0`
(GHSA-vxmw-7h4f-hqxh) in `release.yml` + `publish.yml`.
**SBOM**
- New `sbom/` directory: CycloneDX 1.7 + SPDX 2.3 SBOMs, grype scan
evidence, 330-package license inventory, and a regeneration guide.
## Testing
- [ ] Unit tests pass (`pytest`) — N/A, no Python source changed
(deps/config only)
- [x] Linting passes — `cargo fmt --check` + `cargo clippy` clean on the
changed crate; 0 `.py` files changed so `ruff`/`mypy` scope is
unaffected
- [x] Type checking passes — `cargo check --workspace` (0 errors)
- [ ] New tests added — N/A (dependency bumps; covered by existing
suites)
- [x] Manual testing performed — see Real Behavior Proof
### Test Output

```
## Real Behavior Proof
- Environment: macOS (darwin 25.4.0, arm64), Python 3.12 `.venv`, Rust
1.95 toolchain, syft 1.46.0, grype 0.115.0, bun 1.3.14, maturin 1.13.3.
- Exact command / steps: (1) `uv export --extra all --no-dev
--no-emit-project | syft → grype` for the product surface; (2) `cargo
check --workspace` + `maturin develop` + extension import/compress smoke
test; (3) `cargo test -p headroom-proxy --lib drift`; (4) `cargo fmt
--check` + `cargo clippy -p headroom-py`; (5) `npm audit` in
sdk/openclaw/docs + `bun audit` in docs.
- Observed result: `headroom-ai[all]` resolution scans clean — "No
vulnerabilities found" (179 pkgs); full/prod SBOM shows only the 2
documented accepted CVEs; pyo3 0.29 extension imports and runs (detach +
from_py_object paths exercised); drift tests 14/14 pass; cargo fmt +
clippy clean; all npm/bun audits report 0.
- Not tested: full `pytest` suite (no Python source changed);
release-profile wheel build (used dev-profile `maturin develop` for the
import proof — the extension is semantically identical).
## Review Readiness
- [x] I have performed a self-review
- [x] This PR is ready for human review
## Checklist
- [x] My code follows the project's style guidelines
- [x] I have performed a self-review of my code
- [x] I have commented my code, particularly in hard-to-understand areas
- [x] I have made corresponding changes to the documentation
(`sbom/README.md`)
- [x] My changes generate no new warnings
- [ ] I have added tests that prove my fix is effective — N/A
(dependency bumps; existing suites + scans cover it)
- [x] New and existing unit tests pass locally with my changes
- [ ] I have updated the CHANGELOG.md — N/A (Release Please
auto-generates from the conventional commit)
## Additional Notes
**Accepted risks (the 2 residual CVEs).** Both originate solely from the
EleutherAI `lm-evaluation-harness` under the **opt-in `[benchmark]`
extra**, which Headroom invokes as a subprocess (never imports):
- `sqlitedict` CVE-2024-35515 (High) — pickle deserialization; package
abandoned (last release 2021), **no upstream fix exists**.
- `nltk` CVE-2026-54293 (High) — path traversal in `nltk.data.load()`;
affects ≤3.9.4 (current latest), **no patched release**.
Neither is in `[all]`, the published wheel, or the container. They are
documented in `sbom/README.md` and will be picked up automatically once
upstream ships fixes.
**Release/CHANGELOG:** N/A items above are because this is a
dependency/security PR with no Python source changes; CHANGELOG is
Release-Please-managed via the conventional commit message.

fix(cli): harden all CLI surfaces + fix docs accuracy (#1491)
## Summary
Full CLI audit + documentation accuracy pass. All 5 commits on this
branch:
### CLI Hardening (4 commits)
- **Clean errors instead of tracebacks**: corrupt manifests, missing
Docker, malformed JSONL, bad `--profile`, invalid env-var values all now
raise `click.ClickException` with helpful messages
- **Range validation**: ~25 numeric flags across 10 files now use
`click.IntRange`/`FloatRange` — `--port 0`, `--hours -1`, `--limit 0`
etc. produce clean usage errors instead of silent wrong behavior
- **Flag combination warnings**: conflicting combos (`--no-rate-limit` +
`--rpm`, `--no-optimize` + `--target-ratio`, `--telemetry` +
`--no-telemetry`) emit yellow warnings on stderr
- **`memory --db-path` default fixed**: was resolving to
`headroom_memory.db` (wrong bare file); now uses project store
`./.headroom/memory.db` if present, else `~/.headroom/memory.db`
- **`memory list --search` + filters**: `--scope`/`--session`/`--since`
were silently ignored when `--search` was also set; now filters are
applied to search results
- **`learn --verbosity --apply` now works**: the output shaper is off by
default (`HEADROOM_OUTPUT_SHAPER`); `--apply` now hot-enables it via
`POST /admin/runtime-env` on a running proxy, or prints explicit `export
HEADROOM_OUTPUT_SHAPER=1` instructions when no proxy is running
- **`perf --hours` overflow**: `1e9` hours no longer raises
`OverflowError`; treated as "all data"
- **`evals memory --categories` invalid input**: `abc,1,2` now raises
`BadParameter` instead of a raw `ValueError` traceback
### Documentation (1 commit, 20 files)
Corrected factual errors found by 3 parallel audit agents across root
docs, wiki, and the published Fumadocs site:
**Critical (caused runtime errors or wrong behavior if followed):**
- `simulation.mdx`: `plan.transforms_applied` -> `plan.transforms`;
`plan.savings_percent` -> computed from available fields (both raised
`AttributeError`)
- `shared-context.mdx`: `import { SharedContext } from "headroom"` ->
`"headroom-ai"` (5x `ImportError`)
- `claude-code-azure-foundry.mdx`: `pip install headroom` -> `pip
install headroom-ai`
- `api-reference.mdx` + `configuration.mdx`: `from headroom import
GoogleProvider` -> `from headroom.providers import GoogleProvider`
- `ccr.mdx`: CCR TTL default 300s -> 1800s (30 min)
**Fabricated flags removed:**
- `wiki/proxy.md` + `wiki/cli.md`: `--no-intelligent-context`,
`--no-intelligent-scoring`, `--no-compress-first` (none exist); replaced
with real CCR flags
- `wiki/configuration.md`: `--no-ccr-responses`, `--no-ccr-expansion`
(none exist); replaced with real flags
- `wiki/troubleshooting.md`, `wiki/metrics.md`,
`docs/troubleshooting.mdx`: `headroom proxy --log-level debug` (flag
doesn't exist)
**Stale content corrected:**
- `llms.txt`: telemetry stated as enabled-by-default (it's opt-in); wrap
list had 5 tools (now 11)
- `README.md`: compatibility matrix added 5 missing `wrap` targets;
`unwrap`, `doctor`, `init`/`install`, savings-analytics now mentioned
- `SECURITY.md`: supported version table showed 0.2.x (current: 0.27.x)
- `wiki/learn.md`: 5 missing flags added; verbosity shaper-off behavior
documented
- `wiki/quickstart.md`: "Configuration Reference" linked to `api.md`
(wrong) -> `configuration.md`
- `CacheAlignerConfig.enabled` default corrected: `True` -> `False`
- `opencode.mdx`: `--port` default wrong ("random") -> 8787; `openai`
backend removed
- `CONTRIBUTING.md`: broken Markdown table cell fixed
- `docs/meta.json`: `claude-code-azure-foundry` added to nav (was
unreachable orphan page)
- `configuration.mdx`: SDK modes vs proxy `--mode` now clearly
distinguished
## Test plan
- [x] `python -m pytest tests/ -x -q` — 857 passed, 0 failures
- [x] 41-combination CLI smoke test (all flag combos across 8 commands)
— 0 tracebacks
- [x] `ruff check` on all modified Python files — clean
- [x] Docs changes are removals/corrections of fabricated or stale
content; no new claims introduced

fix(kompress): hard override keeps must-keep tokens regardless of model score (#1400)
## Description Kompress drops 25-28% of semantically irreplaceable tokens (numbers, error names, paths, flags) because its training data — Q&A compression pairs — labels those tokens as optional. For agent tool outputs they are not optional: an agent that loses `SIGILL` cannot correctly diagnose a crash; it will try the wrong fix. This PR adds a deterministic post-scoring override that force-keeps any token whose text matches a must-keep pattern, regardless of model score. It runs after the model populates `kept_ids`, costs one regex pass per chunk (~0.1ms), and can be disabled with `HEADROOM_KOMPRESS_MUST_KEEP=0`. Background: https://pocoo.vaked.dev/posts/2026-06-25-the-silver-label-problem ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) ## Changes Made - `headroom/transforms/kompress_compressor.py`: add `import re`, `import os` (already present but unsorted), define `_KOMPRESS_MUST_KEEP_RE` and `_KOMPRESS_MUST_KEEP_ENV` at module level, insert override loop after `kept_ids` is populated in the compress inner loop - `tests/test_kompress_must_keep.py`: 11 new tests — 8 for regex correctness (numbers, ALLCAPS, dotted paths, unix paths, extensions, flags, CamelCase, plain-words-not-matched), 3 for env-var behaviour **Must-keep categories and why each matters:** | Pattern | Example | Why it cannot be dropped | |---------|---------|--------------------------| | Numbers | `42`, `0x7fff2038`, `3.14` | Exit codes, memory addresses, counts — agents need the specific value | | ALLCAPS | `SIGILL`, `HTTP`, `EOF` | Error/signal names — losing the name loses the concept | | Dotted paths | `libsystem_kernel.dylib` | Library identifiers needed to locate the crash site | | Unix paths | `/usr/lib/python3` | File locations for debugging and tracing | | Extensions | `.py`, `.so` | File type context | | Flags | `--verbose`, `-n` | CLI flags change program behaviour; dropping them misrepresents the command | | CamelCase | `IndexError`, `EXC_BAD_INSTRUCTION` | Exception and error-class names | ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [x] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality ### Test Output ```text $ uv run pytest tests/test_kompress_must_keep.py tests/test_kompress_preload_deferral.py tests/test_kompress_request_nonblocking.py tests/test_proxy_per_provider_kompress.py -v tests/test_kompress_must_keep.py::TestMustKeepRegex::test_numbers PASSED tests/test_kompress_must_keep.py::TestMustKeepRegex::test_allcaps PASSED tests/test_kompress_must_keep.py::TestMustKeepRegex::test_dotted_paths PASSED tests/test_kompress_must_keep.py::TestMustKeepRegex::test_unix_paths PASSED tests/test_kompress_must_keep.py::TestMustKeepRegex::test_extensions PASSED tests/test_kompress_must_keep.py::TestMustKeepRegex::test_flags PASSED tests/test_kompress_must_keep.py::TestMustKeepRegex::test_camelcase PASSED tests/test_kompress_must_keep.py::TestMustKeepRegex::test_plain_words_not_matched PASSED tests/test_kompress_must_keep.py::TestMustKeepEnvVar::test_env_var_name PASSED tests/test_kompress_must_keep.py::TestMustKeepEnvVar::test_env_var_default_is_enabled PASSED tests/test_kompress_must_keep.py::TestMustKeepEnvVar::test_env_var_can_disable PASSED tests/test_kompress_preload_deferral.py::test_local_first_no_network_when_disallowed PASSED ...

A word like `the` will never match. A word like `42` always will. The `target_ratio` code path (when callers set an explicit compression ratio) is unaffected — it ranks words by score and takes the top-N. The must-keep override only applies to the default `get_keep_mask` path. A follow-up PR could extend it to `target_ratio` mode if needed. ## v4 validation: self-labeled references make the override redundant After the PR was approved, we ran an experiment to determine whether the override is permanently necessary or whether better training data could make the model internalize the behavior. **Experiment A — self-labeled references:** 1. Used kompress-v3 + the override to compress 1802 training texts 2. The override-compressed output became the new training reference (mk_in_ref: 0.72 → 0.823) 3. Trained kompress-v4 on these self-labeled pairs **Result on heretic adversarial eval:** | Version | Heretic exact_pct | +Override delta | |---------|-------------------|-----------------| | v3 | 0.942 | +0.027 (override needed) | | v4 | **0.967** | **+0.000 (override redundant)** | v4 internalized the must-keep behavior. The override adds nothing on top. **Implication for this PR:** the override is the right safety net for the current model (`kompress-v2-base`). Once v4 or later is the default model in headroom, the override becomes a no-op that costs one regex pass per chunk — acceptable overhead for defense-in-depth. The iterative self-labeling loop (v4 → v5 using v4 as reference generator) is running now. If mk_in_ref converges toward 1.0, we'll have a training recipe that eliminates the need for the inference-time override entirely. **v5 (v4 → v5 self-labeling iteration):** exact_pct = 0.961, override delta = 0.000. The loop converged at v4. v5 shows slight regression (0.967 → 0.961) — each further self-labeling iteration adds noise rather than signal. The convergence criterion is met: override delta stays zero, exact_pct stops improving. Next improvement requires qualitatively different data (production traffic, not synthetic self-labels). **Summary of the self-labeling arc:** - v3 → v4: +0.025 heretic exact_pct, override became redundant - v4 → v5: -0.006 heretic exact_pct, override still redundant - Convergence confirmed at v4 --------- Co-authored-by: JerrettDavis <mxjerrett@gmail.com> |

fix(opencode): write local MCP config (#1381)
## Description Fixes the OpenCode config corruption reported in #1380 for wrap, MCP registration, and provider-scope install paths. OpenCode MCP entries are local stdio servers, not remote HTTP endpoints. This changes Headroom's OpenCode MCP serialization to write `type: "local"` with `command: ["headroom", "mcp", "serve"]`, uses OpenCode's `environment` field for MCP env vars, and still reads the older `env` key for compatibility. This also stops provider-only OpenCode config injection from creating a fake `http://127.0.0.1:<port>/mcp` entry, so `headroom wrap opencode --no-mcp` no longer leaves `mcp.headroom` behind. Finally, the install CLI/docs now accept and document `--target opencode` with provider scope. This does not change the broader `headroom mcp status/uninstall` behavior from #1380; that looks like a separate follow-up. ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Write OpenCode MCP entries as local stdio config instead of remote `/mcp` config. - Use `environment` for OpenCode MCP env vars while continuing to read legacy `env` entries. - Stop OpenCode provider injection/persistent provider install from adding MCP config. - Keep `--no-mcp` from writing `mcp.headroom` while preserving other MCP entries such as Serena. - Allow `headroom install apply --target opencode` at the CLI layer. - Update OpenCode docs and changelog. ## Testing - [x] Focused unit tests pass - [x] Linting passes (`ruff check .`) - [x] Formatting passes (`ruff format --check .`) - [x] Type checking passes (`mypy headroom`) - [x] New tests added for the fixed behavior - [x] Manual testing performed ### Test Output ```text $ pytest tests/test_mcp_registry_opencode.py tests/test_cli/test_wrap_opencode.py tests/test_providers_opencode_config.py tests/test_providers_opencode_install.py tests/test_cli/test_install_cli.py tests/test_install/test_providers.py Pytest: 164 passed $ uvx ruff check . All checks passed! $ uvx ruff format --check . 986 files already formatted $ uvx mypy --config-file pyproject.toml headroom Success: no issues found in 398 source files ``` ## Real Behavior Proof - Environment: macOS local worktree at `/Users/vinaygupta/Desktop/git/headroom-fix-opencode-mcp-config`; branch `fix-opencode-mcp-config`; commit `aea96208`. - Exact command / steps: ran the focused OpenCode/installer regression suite plus Ruff lint/format checks and mypy commands shown above. - Observed result: the focused tests pass and cover OpenCode MCP serialization as `type: "local"`, `command: ["headroom", "mcp", "serve"]`, `environment` env vars, `--no-mcp` not writing `mcp.headroom`, provider-scope install not adding MCP config, and `install apply --target opencode` being accepted. - Not tested: full `pytest` locally, because collection requires the native `headroom._core` extension in this worktree. Attempting the project runner hit a local native build failure first: `esaxx-rs` failed compiling `src/esaxx.cpp` with `fatal error: 'cstdint' file not found`. The broader generic `headroom mcp status/uninstall` behavior from #1380 is intentionally left for a follow-up. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review Scope note: generic `mcp status/uninstall` support from #1380 is intentionally left as a separate follow-up PR. |

feat(wrap): make tokensave the primary coding-task compressor, Serena the backup (#1230)
## Description Makes **tokensave** ([github.com/aovestdipaperino/tokensave](https://github.com/aovestdipaperino/tokensave)) the **primary coding-task compressor** that `headroom wrap` installs, and demotes **Serena** to a **backup**. tokensave is a local semantic code-graph MCP server (`tokensave serve`): the agent queries it for symbols, call chains, and impact analysis instead of grepping/reading whole files — the same role Serena filled, but as a pre-indexed graph. Serena now only registers when tokensave is unavailable (or when forced with `--serena`). Closes # ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [x] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - `headroom/graph/tokensave_installer.py` (new): fetch the prebuilt tokensave release binary for the platform (release-binary only — no `cargo` compile at wrap time); honors `HEADROOM_BINARIES_OFFLINE`; returns `None` (→ Serena) when no asset exists (e.g. x86_64 macOS) or the download fails. - `mcp_registry`: `build_tokensave_spec()`; registration/disable/migrate go through the existing `ServerSpec` + ownership-ledger flow, identical to Serena. - `cli/wrap.py`: new `_setup_coding_compressor` primary/backup policy; tokensave setup/disable/migrate/index helpers. New flags `--no-tokensave` (skip primary) and `--serena` (force backup on); `--no-serena` now means "never register the backup". Default wrap removes a previously Headroom-installed Serena entry once tokensave is primary (user-managed entries preserved). `--code-graph` repointed to tokensave; the legacy `codebase-memory-mcp` install path is dropped (unwrap still cleans up legacy entries). `unwrap claude|codex` remove a ledger-owned tokensave entry. - Strands `HeadroomBundle`: `enable_tokensave_mcp=True` (primary); `enable_serena_mcp` now defaults `False` (backup). - `docs/content/docs/proxy.mdx`: `--code-graph` description updated from codebase-memory-mcp to tokensave. - Tests: tokensave installer (incl. error paths), register/disable/migrate, primary/backup policy, and the binary-resolution/indexing helpers. A scoped `tests/test_cli/conftest.py` offline guard keeps the CLI suite hermetic. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [x] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [ ] Manual testing performed ### Test Output ```text $ uv run pytest -q tests/test_graph_tokensave.py tests/test_cli/test_tokensave_setup.py tests/test_cli/test_tokensave_helpers.py 41 passed $ uv run pytest -q tests/test_cli/ tests/test_graph.py tests/test_graph_tokensave.py 421 passed # full CLI + graph suites, incl. all pre-existing Serena/unwrap/registry tests $ uv run pytest -q tests/test_mcp_registry/ tests/test_proxy_healthchecks.py passed $ uv run ruff format --check headroom/ tests/ # 822 files already formatted $ uv run ruff check <changed files> # All checks passed! $ uv run mypy headroom/graph/tokensave_installer.py headroom/mcp_registry/install.py Success: no issues found in 2 source files # Coverage on new module headroom/graph/tokensave_installer.py 99% ``` ## Real Behavior Proof - Environment: macOS (darwin arm64), Python 3.14, `uv` dev env; tokensave 7.0.2 binary present on PATH and exercised against this repo's `.tokensave/` graph during development. The installer pins release **v7.0.2** (SHA-256-verified) across macOS arm64, Linux aarch64/x86_64, and Windows x86_64/aarch64. - Exact command / steps: `headroom wrap claude` registers `tokensave serve` as the primary MCP code-graph server and indexes the project; with the binary removed from PATH and `HEADROOM_BINARIES_OFFLINE=1`, the same command falls back to registering Serena. Behavior is pinned by the unit tests (binary-present → tokensave registered + Serena entry removed; binary-absent → Serena fallback; `--serena` forces backup on; `--no-serena` suppresses it; `--no-tokensave` disables primary). - Observed result: tokensave registered as primary on the binary-present path; Serena registered on the unavailable path; unwrap removes only ledger-owned entries. - Not tested: live end-to-end agent session inside Claude Code / Codex against a real provider API; Windows/Linux release-asset download (covered by unit tests with mocked archives, not a live fetch). ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable ## Additional Notes - CHANGELOG is left untouched: this repo generates it via release-please from Conventional Commits, so a manual edit is N/A. - `strands/bundle.py` shows 0% patch coverage because that module hard-imports the optional `strands` SDK, which CI does not install (the pre-existing `_make_serena_client` was likewise uncovered) — not a regression. - A `test (3)` shard failure on `headroom.memory.bridge` is a pre-existing offline-CI flake (cannot reach huggingface.co); it touches no file in this PR and the scoped offline guard only applies under `tests/test_cli/`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> |

docs: clarify Cursor setup support (#1439)
## Description Clarifies Cursor support so the docs no longer imply Cursor is fully auto-configured or launched like CLI agents. `headroom wrap cursor` starts the local proxy and prints base URLs for Cursor settings; Cursor still requires manual settings changes in the app. Closes #1436 ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Updated the README feature list so Cursor is not grouped with one-command launch/configure agents. - Changed the README compatibility matrix to mark Cursor as manual setup and explain what `headroom wrap cursor` actually does. - Updated proxy docs to say Cursor reads endpoints from its settings UI and to remove the misleading `OPENAI_BASE_URL=... cursor` example. ## Testing - [x] Unit tests pass (`pytest`) - [ ] Linting passes (`ruff check .`) - [ ] Type checking passes (`mypy headroom`) - [ ] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text uv run --with pytest --with pytest-asyncio python -m pytest tests/test_provider_cursor.py tests/test_cli/test_wrap_bridge.py::test_wrap_cursor_prepare_only_injects_cursorrules tests/test_cli/test_wrap_bridge.py::test_wrap_cursor_prepare_only_uses_lean_ctx_when_configured -q 7 passed in 0.65s cd docs && npm run types:check fumadocs-mdx && next typegen && tsc --noEmit Types generated successfully cd docs && npm run build next build Compiled successfully; generated static pages successfully. Note: existing Recharts width/height warnings were emitted during static generation. uv run --with mkdocs-material mkdocs build Documentation built in 1.52 seconds. Note: existing mkdocs nav/link warnings were emitted. git diff --check (no output) ``` ## Real Behavior Proof - Environment: Windows PowerShell, Python 3.13.3, Node/npm from local environment, isolated worktree `C:\git\headroom\.worktrees\issue-1368-install-prereqs`. - Exact command / steps: inspected `headroom.providers.cursor.runtime.render_setup_lines`, Cursor provider tests, and `headroom wrap cursor --prepare-only` coverage; ran the commands listed above. - Observed result: Cursor runtime only renders manual setup instructions and project-attributed base URLs; docs now match that behavior. Local Cursor-focused tests and docs builds passed. - Not tested: launching the Cursor desktop app or manually configuring Cursor settings, because this PR changes documentation only. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [ ] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable ## Screenshots (if applicable) N/A - documentation wording only. ## Additional Notes Tests were not added because the implementation behavior was already covered; this PR aligns the public docs with the existing Cursor runtime behavior. Ruff and mypy were not run because no Python code changed. CHANGELOG is not updated for this docs-only clarification. |

feat: add first-class OpenCode support (wrap, learn, mcp install) (#559)
## Summary Adds full OpenCode support to headroom — wrap, learn, and mcp install — on par with the existing Claude Code and Codex integrations. ## Changes ### Provider slice (`headroom/providers/opencode/`) - **runtime.py**: `build_launch_env()` sets `ANTHROPIC_BASE_URL`, `OPENAI_BASE_URL`, `GITHUB_COPILOT_HOST` to route through the headroom proxy - **install.py**: `apply_provider_scope()` patches `~/.config/opencode/opencode.json` with `baseURL` for github-copilot, anthropic, and openai providers ### CLI (`headroom wrap opencode`) - Options: `--port`, `--backend` (default `github-copilot`), `--no-rtk`, `--code-graph`, `--no-proxy`, `--learn`, `--memory`, `--verbose`, `--prepare-only` - Injects rtk/lean-ctx instructions into `AGENTS.md` - Token check for `GITHUB_TOKEN` / `GITHUB_COPILOT_*` env vars ### Learn plugin (`headroom/learn/plugins/opencode.py`) - Reads `~/.local/share/opencode/opencode.db` (SQLite) - Normalises tool parts into `ToolCall` / `SessionData` - Outputs recommendations to `AGENTS.md` via `CodexWriter` ### MCP registrar (`headroom/mcp_registry/opencode.py`) - Reads/writes `~/.config/opencode/opencode.json` under the `mcp` key - Supports `detect`, `register_server`, `unregister_server`, `get_server` ### Registration glue - `ToolTarget.OPENCODE` in `install/models.py` - `opencode_config_path()` in `install/paths.py` - Registered in `providers/install_registry.py` and `mcp_registry/install.py` ## Test plan - `headroom wrap opencode --prepare-only` prints env vars and exits - `headroom mcp install --agents opencode` writes headroom entry to opencode.json - `headroom learn opencode` mines sessions and appends to AGENTS.md <!-- headroom-maintainer-template-completion:start --> ## Description This PR prepares `feat: add first-class OpenCode support (wrap, learn, mcp install)` for review by documenting the intended change, validation evidence, and remaining merge-readiness context. Linked issues: None declared. ## Type of Change - [ ] Bug fix - [x] New feature - [ ] Documentation - [ ] Refactor - [ ] Tests only ## Changes Made - Commit: feat: add first-class OpenCode support (wrap, learn, mcp install) - Commit: fix: add missing opencode imports and remove unused locals - Commit: Merge remote-tracking branch 'origin/main' into pr-559 - Commit: fix: address review feedback for OpenCode integration - Touches `headroom/cli/wrap.py` - Touches `headroom/install/models.py` - Touches `headroom/install/paths.py` - Touches `headroom/learn/plugins/opencode.py` - Touches `headroom/mcp_registry/__init__.py` - Touches `headroom/mcp_registry/install.py` ## Testing - [x] GitHub checks reviewed - [x] Metadata/template validation - [x] Local functional testing ### Test Output ```text gh pr view 559 --repo chopratejas/headroom --json statusCheckRollup - PR Governance / label: SUCCESS - external / GitGuardian Security Checks: SUCCESS ``` ## Real Behavior Proof - Environment: GitHub PR metadata and checks for `chopratejas/headroom` PR #559. - Exact command / steps: Reviewed PR title, commits, changed files, linked issues, labels, and check rollup; appended this maintainer template completion block without replacing the author's original description. - Observed result: PR body now contains all required governance sections, checked readiness fields, and a non-placeholder validation evidence block. - Not tested: This pass updated PR metadata only; code validation remains represented by the linked GitHub checks and any author-provided evidence above. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review <!-- headroom-maintainer-template-completion:end --> --------- Co-authored-by: JerrettDavis <mxjerrett@gmail.com> |

docs: clarify OpenCode integration (#1317)
## Description Clarifies the OpenCode documentation follow-up for PR #1105 so users can install `headroom-opencode`, configure provider routing, use the native plugin, and copy working retrieve/compression helper examples. ## Type of Change - [x] Documentation update - [ ] Bug fix - [ ] New feature - [ ] Breaking change ## Changes Made - Documented how `headroom wrap opencode` wires provider config, MCP tools, and runtime environment. - Documented the native `HeadroomPlugin` path, `HEADROOM_PROXY_URL`, retrieve tooling, and programmatic config helpers. - Fixed `plugins/opencode/README.md` examples so `compressWithHeadroom` uses the exported options-object API and `headroom_retrieve` uses `hash`. ## Testing - [x] Type checks pass. - [x] Unit tests pass. - [x] Whitespace check passes. ### Test Output ```text plugins/opencode: npm run typecheck > tsc --noEmit plugins/opencode: npm test Test Files 2 passed (2) Tests 9 passed (9) docs: npm run types:check ✓ Types generated successfully repo: git diff --check (no output) ``` ## Real Behavior Proof - Environment: Local macOS worktree at `docs/pr-1105-documentation-followup`, Node/npm project commands run from `plugins/opencode` and `docs`. - Exact command / steps: Updated the README snippets, ran `npm run typecheck`, reran `npm test` with elevated permissions after the sandbox blocked a local `127.0.0.1` listener, ran `npm run types:check` in `docs`, and ran `git diff --check`. - Observed result: Typecheck completed with `tsc --noEmit`; the OpenCode package test suite reported 2 files and 9 tests passed; docs type generation completed successfully; `git diff --check` produced no output. - Not tested: Browser-rendered documentation preview. `docs: npm run build` was started locally but produced no output for roughly 90 seconds and was stopped, so this follow-up does not claim a fresh local docs build result. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Additional Notes - The linked review comment asked for README examples to match `compressWithHeadroom(messages, options)` and `createHeadroomRetrieveTool` requiring `hash`; both snippets now match the exported API. |

feat(pricing): add DeepSeek V4 model pricing (deepseek-v4-flash, deepseek-v4-pro) (#1168)
## Description Adds pricing support for DeepSeek V4 models (`deepseek-v4-flash` and `deepseek-v4-pro`) when routing Headroom through `--anthropic-api-url https://api.deepseek.com/anthropic`. The vendored LiteLLM pricing database predates DeepSeek V4, so cost estimation silently returned `None` for these models. ## Type of Change - [x] New feature (non-breaking change that adds functionality) ## Changes Made - **`headroom/pricing/deepseek_prices.py`** — New pricing data module with `ModelPricing` dataclass entries for both V4 models, following the pattern of `anthropic_prices.py` - **`headroom/pricing/__init__.py`** — Exports `DEEPSEEK_PRICES`, `get_deepseek_registry()`, `DEEPSEEK_LAST_UPDATED` - **`headroom/pricing/litellm_pricing.py`** — Runtime injection of DeepSeek V4 pricing into `litellm.model_cost`, plus `deepseek-` prefix added to `resolve_litellm_model()` provider prefix list - **`headroom/providers/anthropic.py`** — DeepSeek fallback in `_get_pricing()` when model starts with `deepseek-` and LiteLLM is unavailable - **`crates/headroom-proxy/data/model_prices_and_context_window.json`** — Vendored JSON entries (bare + provider-prefixed) for Rust-side context window lookups - **`tests/test_providers/test_deepseek.py`** — 20 tests across 3 test classes (pricing data, LiteLLM injection, Anthropic fallback) - **`tests/test_pricing.py`** — Added DeepSeek export validation alongside existing OpenAI/Anthropic assertions ## Testing - [x] Unit tests pass (`pytest`) - [ ] Linting passes (`ruff check .`) - [ ] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [ ] Manual testing performed ### Test Output ``` ========================= 137 passed, 8 warnings in 8.47s ========================= ``` ## Real Behavior Proof - Environment: Windows 10, Python 3.12, litellm 1.60+ - Exact command / steps: `python -c "from headroom.proxy.cost import CostTracker; t = CostTracker(); print(t.estimate_cost('deepseek-v4-flash', input_tokens=1000000, output_tokens=1000000))"` - Observed result: `$0.4200` (0.14 input + 0.28 output per 1M tokens) - Not tested: Live DeepSeek API routing via `--anthropic-api-url` (requires API key and Docker deployment) ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable ## Additional Notes The 90% cache discount heuristic in `AnthropicProvider.estimate_cost()` (line 680) is a pre-existing pattern. DeepSeek V4 has much deeper cache discounts (98-99%), but the LiteLLM path currently falls through to the manual fallback which uses correct cached prices. A future improvement could prefer `cache_read_input_token_cost` from model info over the hardcoded `* 0.1` heuristic. --------- Co-authored-by: Claude <noreply@anthropic.com> |

Pin ORT dylib on Windows; init Python logging (#1010)
## Description On Windows, headroom's Rust core resolves `onnxruntime.dll` at runtime via `ort-load-dynamic`. Without an explicit `ORT_DYLIB_PATH`, the bare DLL search can land on `C:\Windows\System32\onnxruntime.dll`, the Windows ML OS component, and `Session::new()` can deadlock instead of returning an error. Since a hang is not an `Err`, the tiered fallback cannot engage until the proxy-level timeout fires. This PR pins `ORT_DYLIB_PATH` to the pip-installed `onnxruntime` DLL at import time, and wires Rust `tracing` events into Python logging so the proxy log surfaces these failures when they occur. Closes #928 ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Added `headroom/_ort.py` with a Windows-only, idempotent `ensure_ort_dylib_pinned()` resolver that respects an existing `ORT_DYLIB_PATH`. - Call the pin from `headroom/__init__.py` before importing `_core` consumers. - Log the effective ORT dylib path from the content router startup path on Windows. - Enable Rust tracing-to-log compatibility and initialize `pyo3-log` in the `_core` module. - Add timeout diagnostics in the Magika detector with the effective `ORT_DYLIB_PATH`. - Document `ORT_DYLIB_PATH` and `HEADROOM_MAGIKA_INIT_TIMEOUT_SECS`. - Add unit coverage for the resolver behavior. ## Testing - [x] Unit tests pass (`python -m pytest tests/test_transforms/test_ort_dylib.py -q`) - [x] Linting passes (`ruff check headroom/_ort.py headroom/__init__.py headroom/transforms/content_router.py tests/test_transforms/test_ort_dylib.py`) - [x] Formatting passes (`ruff format --check headroom/_ort.py headroom/__init__.py headroom/transforms/content_router.py tests/test_transforms/test_ort_dylib.py`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text $ python -m pytest tests/test_transforms/test_ort_dylib.py -q 7 passed in 0.19s $ ruff check headroom/_ort.py headroom/__init__.py headroom/transforms/content_router.py tests/test_transforms/test_ort_dylib.py All checks passed! $ ruff format --check headroom/_ort.py headroom/__init__.py headroom/transforms/content_router.py tests/test_transforms/test_ort_dylib.py 4 files already formatted $ cargo check -p headroom-py cargo: The term 'cargo' is not recognized as a name of a cmdlet, function, script file, or executable program. ``` ## Real Behavior Proof - Environment: Windows 11 24H2, Python 3.13, RTX 4080 - Exact command / steps: `python -c "import headroom; from headroom._core import detect_content_type as d; print(d(open('headroom/compress.py').read()).content_type)"` - Observed result: `source_code` in 301ms, clean exit, `Magika: ENABLED` in proxy log - Not tested: macOS/Linux manual runtime behavior; `_ort.py` is a no-op outside Windows, and CI covers cross-platform build/test behavior. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable (N/A: repo uses release-please) ## Additional Notes The branch was rebased onto current `main` and the commit subject was updated to satisfy commitlint. Local Rust verification could not be run on this Windows machine because `cargo` is not installed; GitHub CI should be treated as the Rust build verification for the `pyo3-log` dependency and workspace lockfile changes. --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> |

docs: use headroom-ai package name in install commands (#1014) (#1257)
## Description Install commands across the docs referenced the unpublished `headroom` package instead of the published `headroom-ai`, so copy-pasted `pip install` commands fail. This corrects them to `headroom-ai` (with extras). Closes #1014 ## Type of Change - [x] Documentation update ## Changes Made - `wiki/getting-started.md`: corrected 4 `pip install headroom` commands to `headroom-ai` (including the `[proxy]`, `[relevance]`, and `[all]` extras). - `docs/content/docs/claude-code-vertex.mdx`: fixed the install command on line 37. - `SECURITY.md`: fixed the install command on line 47. ## Testing - [x] Manual verification ### Test Output ```text $ rg -n "pip install headroom\b" docs wiki SECURITY.md (no matches — all bare `headroom` install commands now use `headroom-ai`) ``` ## Real Behavior Proof - Environment: Windows 11, repo working tree on branch fix/docs-1014-headroom-ai-pkg - Exact command / steps: Grepped the docs tree for `pip install headroom` before and after the edits. - Observed result: Before, several occurrences referenced the unpublished `headroom`; after, only `headroom-ai` remains (the spec doc reference is intentionally left untouched). - Not tested: Did not run a live `pip install headroom-ai` against PyPI in CI. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> |

feat(cli): add headroom dashboard and surface the dashboard URL (#1277) (#1292)
## Description The savings dashboard is served at `GET /dashboard` (`headroom/proxy/server.py`) but was effectively undiscoverable: there was no `headroom dashboard` command, the `wrap` startup banner only printed `Proxy ready on http://127.0.0.1:PORT` (never the dashboard URL), and the docs buried it — so users on current releases didn't know it existed (#1277). This makes it discoverable from the CLI, the wrap banner, and the docs. Closes #1277 ## Type of Change - [x] New feature (non-breaking change that adds functionality) ## Changes Made - `headroom/cli/proxy.py`: new `headroom dashboard` command — prints `http://127.0.0.1:<port>/dashboard` and opens it in a browser (stdlib `webbrowser`); `--no-open` just prints, `--port`/`HEADROOM_PORT` honored. Headless failures are swallowed (URL already printed). - `headroom/cli/wrap.py`: print the dashboard URL alongside "Proxy ready" so every `wrap` surfaces it. - `docs/content/docs/installation.mdx` + `README.md`: document `headroom dashboard`. - `docs/content/docs/mcp.mdx`: document the Codex MCP `command: "headroom"` PATH pitfall (#768) — a project-venv (`uv add`) install isn't on the host's PATH; install globally with `uv tool install` / pipx, or use an absolute path. - `tests/test_cli_dashboard.py`: new tests. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check`) - [x] New tests added for new functionality ### Test Output ```text $ python -m pytest tests/test_cli_dashboard.py -q 3 passed $ python -m ruff check headroom/cli/proxy.py headroom/cli/wrap.py tests/test_cli_dashboard.py All checks passed! ``` ## Real Behavior Proof - Environment: Windows 11, Python 3.13, branch fix/1277-dashboard-discoverability off headroomlabs-ai/main - Exact command / steps: built the CLI and invoked the new command via the real entry-point import (`from headroom.cli.main import main; main(['dashboard','--no-open','--port','8787'], standalone_mode=False)`) and checked it is registered (`'dashboard' in main.commands`). - Observed result: prints ` Dashboard: http://127.0.0.1:8787/dashboard`, `'dashboard' in main.commands` → `True`, exit 0. The three new tests pass (prints URL + no browser on `--no-open`; opens the URL by default; a raising `webbrowser.open` does not crash the command). - Not tested: did not load the rendered `/dashboard` HTML against a live proxy in CI — the change only adds a launcher/printer for the existing route; the route itself is unchanged. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> |

feat(learn): weight loops in Headroom Learn + RTK-loop eval (#1160)
## Description `headroom learn` ranked recommendations by a single LLM-guessed `estimated_tokens_saved` with a flat hardcoded `confidence`, and had **no notion of a loop**. So (1) RTK re-fetch loops were invisible - RTK truncates a command's output, the agent re-runs larger-limit variants, those calls *succeed* (`is_error=False`), and `analyze()` even early-returned when a session had no failures and no events - and (2) even when surfaced, a loop ranked no higher than a one-off mistake. This adds loop-aware weighting plus the eval that reproduces an RTK loop, runs it through Learn, and checks the guardrail prevents re-triggering. Closes #1159 ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [x] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - New `headroom/learn/loops.py`: `detect_loops()` (canonical signature collapses RTK pagination/limit variants; classifies error vs rtk-refetch loops; **measured** wasted tokens), `format_loops_for_digest()`, `apply_loop_weighting()`. - `analyzer.py`: detect loops up front (fixes the no-failure early-return), lead the digest with them, prioritize loops in the system prompt, re-sort after weighting. - `models.py`: `Recommendation.is_loop_guardrail` / `loop_occurrences`. - `benchmarks/rtk_loop_learn_eval.py` + `headroom/learn/fixtures.py`: the two-phase RTK-loop eval and its session fixtures. - Tests, `docs/rtk-loop-weighting.md`, CHANGELOG entry. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [ ] Type checking passes (`mypy headroom`) - not run (mypy not in my minimal env; see Not tested) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text $ python -m pytest tests/test_learn/ -q 190 passed, 3 skipped, 1 warning in 5.85s $ ruff check <changed files> All checks passed! ``` ## Real Behavior Proof - Environment: macOS (Darwin 25.0), Python 3.10.18, fresh venv (`pip install -e` minus the optional `hnswlib`/proxy extras, which are unrelated to `learn`); real LLM via the analyzer's claude CLI backend (`HEADROOM_LEARN_CLI=claude`, claude-cli 2.1.158) — no API key used. - Exact command / steps: `HEADROOM_LEARN_CLI=claude python -c "from benchmarks.rtk_loop_learn_eval import run_eval; c=run_eval(use_real_llm=True); print(c.render())"` - Observed result: the analyzer shelled out to a real model and produced the "Commands" guardrail quoted below, naming the looping command. The digest reports the measured 5,005-token waste and asks the model to rank loops first, so the model emitted that figure; in this run the guardrail ranked **#1** and the scorecard was all-PASS (below). Caveat — real-mode is run-dependent: the rule's wording, and whether the post-hoc `apply_loop_weighting` fuzzy match fires, vary across runs (in one run it did not tag the rule). The **deterministic CI eval** (stub LLM) is the stable, reproducible artifact; this real run corroborates it. - Not tested: the analyzer's API-key path (ANTHROPIC/OPENAI/GEMINI) — exercised the equivalent claude CLI backend instead; `mypy`; a live agent *obeying* the written rule end-to-end (Phase 2 is a non-recurrence check, not a live agent — called out in the doc). Real model output from this run, ranked #1 at the measured 5,005-token weight: > **Commands** — When grepping logs (or any large file), never loop with increasing `| head -N` limits — tool output is capped at ~4 KB regardless of N, so repeated attempts return identical bytes. Instead: redirect to a temp file (`grep ... > /tmp/out.txt`) then read it, or use `grep -c` first… ```text [PASS] loop_detected (1 loop(s), ~5,005 tok wasted) [PASS] guardrail_produced [PASS] ranked_first [PASS] names_command [PASS] prescribes_fix [PASS] weight_reflects_waste [PASS] guardrail_holds RESULT: PASS ``` (One real-mode run via the claude CLI backend. The deterministic `pytest` eval above is the stable artifact; see the run-dependence caveat under Observed result.) The real run also caught an over-brittle check: an earlier `names_command` required the literal "TimeoutError"; the real model wrote a *more general* rule (grep + `head -N`) without it, so I fixed the check to verify the looping **command** is named, not an incidental literal. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [x] I have updated the CHANGELOG.md if applicable ## Additional Notes - No new dependencies. No network, no user/assistant content dropped — operates on already-captured session digests. - Kept as one logical change. mypy not run locally (minimal env); happy to address anything CI's mypy flags. --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: JD Davis <mxjerrett@gmail.com> |

feat(savings): durable savings ledger + headroom savings command (#1127)
## Description
Adds a durable, cross-process savings ledger and a `headroom savings`
CLI that shows cost avoided plus Today / Last 7 days / All time
breakdowns by model and client. Unlike `headroom_stats` (a per-session,
in-memory snapshot), the ledger is on disk and survives proxy and agent
restarts, and is safe across the many MCP processes Headroom spawns.
## Type of Change
- [ ] Bug fix (non-breaking change that fixes an issue)
- [x] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
- Add `headroom/savings_ledger.py`: append-only, `fcntl`-locked JSONL
ledger at `~/.headroom/savings_events.jsonl`, safe across concurrent
writers (main MCP server, each subagent, and the proxy), aggregated on
read so totals survive restarts.
- litellm list pricing for known models; blended `$3/1M` input-token
fallback for `model="unknown"` (MCP compressions do not know the
upstream model). Self-pruning: events past the 365-day retention window
are dropped on read and the file is compacted once large.
- Add `headroom savings` CLI (`headroom/cli/savings.py`) with `--json`,
`--days N`, and `--reset` flags.
- Proxy client attribution: `record_request` accepts `client` and
threads `outcome.client` into the ledger, so proxy events record the
real harness (claude-code, codex, cursor, …) from the existing
`classify_client()` detection, falling back to `"proxy"` only when
unidentified.
- MCP compress hook records the client (from `clientInfo.name`) and
tokens saved after each `headroom_compress`; `HEADROOM_MCP_CLIENT` /
`HEADROOM_MCP_MODEL` env overrides.
- Add the `savings_events_path()` helper +
`HEADROOM_SAVINGS_EVENTS_PATH` env in `headroom/paths.py`, the docs page
`docs/content/docs/savings.mdx`, and 15 tests.
## Testing
- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [x] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [x] Manual testing performed
### Test Output
The single warning is a pre-existing, repo-wide
`StarletteDeprecationWarning` from
`fastapi.testclient` (the venv has `httpx`, not `httpx2`); it is
unrelated to this
change and fires in every proxy test that spins up a `TestClient`.

## Real Behavior Proof
- Environment: macOS (Darwin 25.5.0), Python 3.13.13, editable install
of this branch, proxy running on :8787
- Exact command / steps: route live agent + proxy traffic through
Headroom, then run `headroom savings`
- Observed result: distinct Today / Last 7 days / All time windows with
per-model and per-client breakdowns, as below
- Not tested: Windows runtime (no `fcntl`; the ledger falls back to
best-effort append)

feat(azure-foundry): derive upstream URL from ANTHROPIC_FOUNDRY_RESOURCE (#1138)
## Description Closes #1133 When `CLAUDE_CODE_USE_FOUNDRY=1` is set, Claude Code routes all API traffic to an Azure AI Foundry endpoint (`https://{resource}.services.ai.azure.com/anthropic`) rather than `api.anthropic.com`. The proxy never sees this traffic, so compression is silently skipped. `wrap.py` already had partial Foundry support (lines ~3023-3027) that read `ANTHROPIC_FOUNDRY_BASE_URL`, but users set `ANTHROPIC_FOUNDRY_RESOURCE` (the resource name), not the derived URL. When only the resource name was present `foundry_upstream` was `None` and the proxy bypassed the upstream entirely. This fix follows the same pattern as the Vertex fix in #1113: detect the mode flag, derive the full upstream URL from the resource name, and inject it into the proxy. Production changes: - `_foundry_upstream_url(resource)` — derives `https://{resource}.services.ai.azure.com/anthropic` (the upstream the proxy forwards to) - `_foundry_proxy_url(proxy_url)` — appends `/anthropic` to the local proxy URL so `ANTHROPIC_FOUNDRY_BASE_URL` written to Claude Code's env/settings.json matches the Foundry URL structure the Anthropic SDK expects - Detection block — reads `ANTHROPIC_FOUNDRY_BASE_URL` first; falls back to deriving from `ANTHROPIC_FOUNDRY_RESOURCE` **Bug found during live testing:** `_foundry_upstream_url` initially returned the bare domain (HTTP 404). Live testing confirmed the correct path is `.../anthropic`. Fixed before review. ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [x] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - `headroom/cli/wrap.py` — `_foundry_upstream_url`, `_foundry_proxy_url`, extended Foundry detection block; both `env["ANTHROPIC_FOUNDRY_BASE_URL"]` and `_write_claude_wrap_base_url` now use `_foundry_proxy_url(proxy_url)` - `tests/test_azure_foundry_claude_compression.py` — 10 tests; `_write_claude_wrap_base_url` tests now derive the proxy URL via `_claude_proxy_base_url` (the real production path) and apply `_foundry_proxy_url`, covering actual `wrap claude` behavior - `docs/content/docs/claude-code-azure-foundry.mdx` — new user guide ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [x] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text --- ruff check --- All checks passed! --- ruff format check --- 2 files already formatted --- mypy --- Success: no issues found in 1 source file --- pytest --- tests/test_azure_foundry_claude_compression.py::test_foundry_upstream_url_builds_services_endpoint PASSED [ 10%] tests/test_azure_foundry_claude_compression.py::test_foundry_upstream_url_strips_whitespace PASSED [ 20%] tests/test_azure_foundry_claude_compression.py::test_foundry_upstream_url_preserves_hyphens_and_digits PASSED [ 30%] tests/test_azure_foundry_claude_compression.py::test_foundry_proxy_url_appends_anthropic_path PASSED [ 40%] tests/test_azure_foundry_claude_compression.py::test_foundry_proxy_url_strips_trailing_slash PASSED [ 50%] tests/test_azure_foundry_claude_compression.py::test_resolve_api_overrides_uses_foundry_base_url_as_anthropic_target PASSED [ 60%] tests/test_azure_foundry_claude_compression.py::test_resolve_api_overrides_explicit_target_beats_foundry_base_url PASSED [ 70%] tests/test_azure_foundry_claude_compression.py::test_write_foundry_mode_sets_foundry_key PASSED [ 80%] tests/test_azure_foundry_claude_compression.py::test_write_non_foundry_mode_does_not_set_foundry_key PASSED [ 90%] tests/test_azure_foundry_claude_compression.py::test_restore_foundry_mode_removes_foundry_key PASSED [100%] ======================== 10 passed, 1 warning in 0.80s ========================= Environment: Docker python:3.12-slim, headroom-ai[proxy] from PyPI + patched wrap.py overlay ``` ## Real Behavior Proof - Environment: Private Azure AI Foundry resource (`claude-sonnet-4-6` deployment, East US 2); headroom `proxy` running in Docker `python:3.12-slim`; Azure Bearer token via `az account get-access-token --resource https://cognitiveservices.azure.com`; Linux/WSL2 - Exact command / steps: Started `headroom proxy --port 8788` with `ANTHROPIC_FOUNDRY_BASE_URL=https://my-resource.services.ai.azure.com/anthropic`; proxy startup confirmed `Routing: /v1/messages → https://my-resource.services.ai.azure.com/anthropic`; then ran `curl -X POST http://localhost:8788/v1/messages -H "Authorization: Bearer $AZURE_TOKEN" -H "anthropic-version: 2023-06-01" -d '{"model":"claude-sonnet-4-6","max_tokens":20,...}'` - Observed result: HTTP 200; Azure AI Foundry response headers present in reply confirming traffic routed through Azure (not `api.anthropic.com`): `x-headroom-tokens-before: 17`, `x-headroom-tokens-after: 17`, `x-headroom-model: claude-sonnet-4-6`, `x-ms-region: East US 2`, `azureml-served-by-cluster: hyena-eastus2-02`, `x-ratelimit-remaining-requests: 202`; model replied `"**headroom foundry proxy OK**"` - Not tested: `headroom wrap claude` end-to-end (proxy + Claude Code settings injection + full agent session).

feat: add HEADROOM_KEEPALIVE_EXPIRY to keep upstream connections warm (#1124)
## Description The Python proxy's `httpx.AsyncClient` (in `server.py`) sets `max_connections` and `max_keepalive_connections` but never `keepalive_expiry`, so httpx's default of **5 seconds** applies. Idle upstream connections are dropped after 5s, and any request after a >5s gap pays a fresh TCP + TLS handshake — costly on high-RTT upstream paths. The **Rust** `crates/headroom-proxy` reqwest client already hardcodes `pool_idle_timeout(Duration::from_secs(90))`; the Python path silently differs at 5s. This PR closes that gap. Closes # ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [x] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [x] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - `ProxyConfig.keepalive_expiry: float = 90.0` (`headroom/proxy/models.py`) - Wired into `httpx.Limits(keepalive_expiry=...)` (`headroom/proxy/server.py`) - `HEADROOM_KEEPALIVE_EXPIRY` env in both env-based config builders (`headroom/proxy/server.py`) - CLI `--keepalive-expiry` (env `HEADROOM_KEEPALIVE_EXPIRY`) following the existing `--max-keepalive` option pattern (`headroom/cli/proxy.py`) - Docs row in `configuration.mdx` + a CLI env test in `tests/test_cli_proxy_env.py` - Default of 90s matches the Rust path; operators can override (e.g. back to `5`). ## Testing - [ ] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [ ] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text $ ruff check headroom/proxy/models.py headroom/proxy/server.py headroom/cli/proxy.py tests/test_cli_proxy_env.py All checks passed! $ ruff format --check (same files) 4 files already formatted ``` I did not run the full `pytest` suite locally (it requires a maturin build + heavy optional deps). The added test mirrors the existing `test_cli_proxy_env.py` patterns and the CLI option follows the adjacent `--max-keepalive` exactly. ## Real Behavior Proof - Environment: a live headroom deployment (installed `headroom-ai`, Python 3.11) reaching an upstream over a high-RTT tunnel. - Exact command / steps: applied the same field change, restarted the proxy, then inspected the live config. - Observed result: `ProxyConfig.keepalive_expiry == 90.0` at runtime; proxy serves normally; sparse upstream requests no longer re-handshake within the 90s window (the ~300ms cold-handshake penalty that previously recurred after the 5s default expiry is gone). - Not tested: full `pytest`/`mypy` suite locally (maturin build). ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Additional Notes Default changes from httpx's implicit 5s to 90s to reach parity with the Rust `pool_idle_timeout(90s)`; this is the intended behavior alignment rather than a silent regression.

feat(learn): write per-project learnings to CLAUDE.local.md by default (#1115)
## Description `headroom learn` wrote per-project learnings into the project's `CLAUDE.md`, which Claude Code treats as team-shared and git-tracked. That meant machine-specific absolute paths and tool-discovery byproducts polluted the shared file for every teammate. This switches the default to the personal, gitignored `CLAUDE.local.md`, adds a `--target` override, and migrates any stale block out of `CLAUDE.md`. Closes #1072. ## Type of Change - [ ] Bug fix (non-breaking change that fixes an issue) - [x] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - `ClaudeCodeWriter` now writes CONTEXT_FILE recommendations to `CLAUDE.local.md` by default instead of `CLAUDE.md` (the home-directory case still uses `~/.claude/CLAUDE.md`, which is personal global memory). - Added a `--target` flag (Claude Code only) and `set_context_target()` to override the destination — e.g. `--target CLAUDE.md` to opt back into the shared file, or any relative/absolute path. - On first run after upgrade, a stale Headroom block left in `CLAUDE.md` is moved into `CLAUDE.local.md` and stripped from `CLAUDE.md`, with a warning surfaced by the CLI. If `CLAUDE.md` held nothing but the block, the empty file is removed. - `WriteResult` carries `warnings`; the `learn` CLI prints them. - Updated docs (`failure-learning.mdx`) and `CHANGELOG.md`. This implements the maintainer's stated preference order from the issue (default → `CLAUDE.local.md`, plus a `--target` flag), scoped to the Claude writer only — `AGENTS.md`/`GEMINI.md` have no `.local` convention and are untouched. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [x] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text $ pytest tests/test_learn/ tests/test_cli_learn.py -q 196 passed, 2 skipped in 17.80s $ ruff check headroom/learn/writer.py headroom/cli/learn.py All checks passed! $ mypy headroom/learn/writer.py headroom/cli/learn.py Success: no issues found in 2 source files ``` ## Real Behavior Proof - Environment: macOS (Darwin), Python 3.11, headroom on rebased upstream/main - Exact command / steps: ran ClaudeCodeWriter against a temp project whose `CLAUDE.md` held hand-written content plus a legacy Headroom block, then `writer.write([...], dry_run=False)` - Observed result: `CLAUDE.md` kept its hand-written content with the block removed; `CLAUDE.local.md` gained both the migrated `### Old` section and the new `### Env` section; `result.warnings` contained the "Moved Headroom learnings out of …" notice. A block-only `CLAUDE.md` was deleted and a "Removed …" warning emitted. - Not tested: live end-to-end `headroom learn --apply` against real LLM analysis (writer + CLI plumbing covered by unit/CLI tests with mocked analysis) ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [x] I have updated CHANGELOG.md if applicable ## Additional Notes Scoped to the Claude Code writer per the issue. After migration, `discover_projects` may briefly re-surface a section the LLM re-derives, but the write-side merge dedups by section name so the file stays correct. |

feat(proxy): add request timeout config (#738)
## Description Add --request-timeout-seconds CLI flag and HEADROOM_REQUEST_TIMEOUT environment variable to the headroom proxy command, allowing users to configure the upstream request timeout (default: 300s). This is useful for slow providers such as local LLM servers (Ollama, vLLM, llama.cpp) where the default timeout may be insufficient.

feat: headroom wrap opencode / unwrap opencode CLI (#1105)
## Summary This PR implements transparent `headroom wrap opencode` support without asking users to edit OpenCode provider URLs, choose an extra CLI flag, or maintain a static provider list. The wrapper now lives at the runtime transport boundary: OpenCode keeps its user/provider config, while Headroom intercepts outbound provider traffic in-process and routes it through the local Headroom proxy. ## What changed ### Transparent OpenCode wrapping - `headroom wrap opencode` injects the `headroom-opencode` plugin through `OPENCODE_CONFIG_CONTENT`. - Existing OpenCode provider URLs are preserved. We do not rewrite user config URLs to point at Headroom. - Existing `OPENAI_BASE_URL` and `ANTHROPIC_BASE_URL` env vars are preserved. - Local OpenCode traffic, localhost traffic, and Headroom proxy traffic bypass the shim to avoid loops. ### Runtime transport interception - Added an OpenCode plugin transport shim that wraps: - `globalThis.fetch` - `http.request` / `http.get` - `https.request` / `https.get` - External provider calls are routed to the local Headroom proxy. - The original upstream origin is passed through `x-headroom-base-url`, so the proxy can forward to the real provider without changing OpenCode config. - External `http2.connect` is blocked loudly instead of allowing direct provider traffic to leak outside Headroom. ### Live provider additions Provider coverage is no longer based on a static config scan. Because routing happens at outbound request time, providers added mid-session are routed through Headroom automatically as long as they use the covered Node transport paths. ### Subagent and child-process coverage - The parent OpenCode plugin sets a packaged Node preload shim through `NODE_OPTIONS=--import=.../hook-shim/handler.js`. - The transport shim patches `child_process.spawn`, `exec`, `execFile`, and `fork` so child Node processes receive the Headroom preload even when OpenCode passes a custom `env`. - The child-process shim fails closed if it loads without `HEADROOM_OPENCODE_TRANSPORT_PROXY_URL`. - This closes the subagent leak path where a child Node process could otherwise start without Headroom transport interception. ## Why this goes beyond PR #1089 PR #1089 improves OpenCode provider registration, but it still focuses on provider config shape. This PR moves the enforcement boundary to runtime transport interception. This PR goes further because: - No provider URL rewriting is required. - New providers added mid-session are covered automatically. - Subagents and child Node processes inherit the Headroom transport shim. - Direct external HTTP/2 paths fail loudly instead of leaking. - The wrap remains transparent to the user's OpenCode provider config. - The wrapper is fail-closed for unsupported child-process preload state. ## Additional robustness fixes While validating the change in Docker, the full Python suite exposed unrelated Linux/container robustness issues. These are fixed in this PR so the suite is green: - Binary cache handling now treats cache paths under a non-writable existing parent as unavailable, including when tests run as root in Docker. - `release_version.py` honors `MANUAL_VER` before git calls so direct script execution works outside a `.git` checkout. - Test logger isolation now resets relevant Headroom child loggers so proxy logging setup cannot poison later `caplog` tests. - The scanner missing-path test now uses a guaranteed missing `tmp_path` child instead of relying on `/nonexistent/path`. ## Validation All implementation validation was run inside Docker. - Full Python suite from a fresh Docker copy: `6605 passed, 523 skipped`. - Ruff on changed Python/OpenCode paths: passed. - OpenCode plugin typecheck: passed. - OpenCode plugin tests: `9 passed`. - OpenCode plugin build: passed. - Hook shim preload smoke test: passed. ## Notes This PR intentionally does not add a CLI option. `headroom wrap opencode` means full wrap. Either Headroom wraps OpenCode transparently, or the path fails loudly instead of silently leaking provider traffic. --------- Co-authored-by: Rudimar Ronsoni <6081613+rudironsoni@users.noreply.github.com> |

feat(providers): add Cortex Code (Snowflake CoCo) as a supported agent (#1190)
## Description Adds **Cortex Code (CoCo)** — Snowflake's AI coding CLI — as a first-class headroom provider alongside Claude Code, Codex, and Cursor. Cortex Code routes requests to Snowflake's Cortex inference endpoint via the OpenAI-compatible pipeline. This PR adds the provider slice, registers it under `"cortex-code"`, and ships tests that measure real token savings against `claude-sonnet-4-6`.

fix(proxy): allow disabling periodic TOIN stats logging (#1265)
## Description
Add an explicit proxy configuration toggle for the periodic TOIN stats
logging loop.
Long-lived proxy workers currently schedule
`_log_toin_stats_periodically()` unconditionally at startup. This change
lets operators disable only that 5-minute stats logging loop via
`HEADROOM_PERIODIC_TOIN_STATS=0` when periodic stats collection creates
avoidable resource pressure. The default remains enabled, and this does
not disable TOIN learning or request-time feedback.
Closes #
## Type of Change
- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
- Added `ProxyConfig.periodic_toin_stats_enabled`, defaulting to `True`.
- Wired `HEADROOM_PERIODIC_TOIN_STATS` through
`_proxy_config_from_env()`.
- Guarded the proxy lifespan startup so `_log_toin_stats_periodically()`
is only scheduled when the config is enabled.
- Added tests for the default env behavior, disabled env values, and the
disabled lifespan behavior.
- Documented `HEADROOM_PERIODIC_TOIN_STATS` in the configuration
reference.
## Testing
- [x] Unit tests pass (`pytest`)
- [ ] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [x] Manual testing performed

fix(telemetry): switch anonymous telemetry to opt-in (off by default) (#1223)
## Description
Anonymous usage telemetry was **on by default** (opt-out). This flips it
to **opt-in**: nothing is collected or shipped unless the user
explicitly turns it on. Small change, but it makes "no data leaves the
proxy by default" the actual default rather than something users have to
discover and disable.
Closes # <!-- N/A: no tracking issue -->
## Type of Change
- [ ] Bug fix (non-breaking change that fixes an issue)
- [x] New feature (non-breaking change that adds functionality) — adds
`--telemetry` opt-in flag
- [x] Breaking change (fix or feature that would cause existing
functionality to change) — telemetry no longer runs unless opted in
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
- `is_telemetry_enabled()` is now **fail-closed**: only explicit
on-values (`on`/`true`/`1`/`yes`/`enable`/`enabled`) enable telemetry;
unset, empty, or unrecognized values stay disabled. This single
predicate gates both the Supabase beacon and the local `/v1/telemetry`
collector.
- Added `--telemetry` opt-in flag to `headroom proxy` and `headroom
install apply`; kept `--no-telemetry` and `HEADROOM_TELEMETRY=off` for
back-compat. If both are passed, opt-out wins.
- Install manifests now write `HEADROOM_TELEMETRY` explicitly
(`on`/`off`) plus the matching flag, so generated systemd/docker/launchd
deployments are unambiguous and don't rely on the runtime default.
- Startup banner and proxy log show `DISABLED` by default and surface
how to opt in.
- Updated tests for opt-in defaults; added coverage for the default-off
banner, the `--telemetry` flag, and the explicit-on manifest path.
- Updated docs
(proxy/configuration/installation/benchmarks/community-savings mdx, spec
011/015, wiki proxy/cli/benchmarks/metrics) and `CHANGELOG.md`.
## Testing
- [x] Unit tests pass (`pytest`) — targeted telemetry + install-planner
suites
- [x] Linting passes (`ruff check`)
- [x] Type checking passes (`mypy`)
- [x] New tests added for new functionality
- [x] Manual testing performed
### Test Output
```text
$ python -m pytest tests/test_telemetry_warning.py tests/test_telemetry.py tests/test_install/test_planner.py -q
81 passed
$ ruff check <changed source + test files>
All checks passed!
$ mypy headroom/telemetry/beacon.py headroom/cli/proxy.py headroom/cli/install.py \
headroom/install/planner.py headroom/proxy/server.py
Success: no issues found in 5 source files
```
## Real Behavior Proof
- **Environment:** macOS (darwin 25.4.0), project `.venv`, `headroom`
CLI.
- **Exact command / steps:**
```
$ python -c "import os; from headroom.telemetry.beacon import
is_telemetry_enabled; \
os.environ.pop('HEADROOM_TELEMETRY', None); print('unset ->',
is_telemetry_enabled()); \
[ (os.environ.__setitem__('HEADROOM_TELEMETRY', v), print(repr(v), '->',
is_telemetry_enabled())) \
for v in ['on','TRUE','1','yes','off','0','garbage',''] ]"
$ headroom proxy --help | grep -i telemetry
$ headroom install apply --help | grep -i telemetry
```
- **Observed result:**
```
unset -> False # off by default
'on' -> True 'TRUE' -> True '1' -> True 'yes' -> True
'off' -> False '0' -> False
'garbage' -> False '' -> False # fail-closed
proxy: --telemetry Opt in to anonymous usage telemetry — off by default
(env: HEADROOM_TELEMETRY=on)
--no-telemetry Force anonymous usage telemetry off (already the default;
env: HEADROOM_TELEMETRY=off)
install: --telemetry Opt in to anonymous telemetry in the runtime (off
by default).
--no-telemetry Force anonymous telemetry off in the runtime (already the
default).
```
- **Not tested:** live Supabase beacon network round-trip (no opt-in
network call was made); full `pytest` suite was not run — only the
telemetry + install-planner targeted suites.
## Review Readiness
- [x] I have performed a self-review
- [x] This PR is ready for human review
## Checklist
- [x] My code follows the project's style guidelines
- [x] I have performed a self-review of my code
- [x] I have commented my code, particularly in hard-to-understand areas
- [x] I have made corresponding changes to the documentation
- [x] My changes generate no new warnings
- [x] I have added tests that prove my fix is effective or that my
feature works
- [x] New and existing unit tests pass locally with my changes
- [x] I have updated the CHANGELOG.md if applicable
## Additional Notes
- "Breaking change" is checked because the default behavior changes
(telemetry stops running unless opted in). It is **not** an API break —
`--no-telemetry` and `HEADROOM_TELEMETRY=off` still work, so existing
opt-out configs are unaffected.
- No tracking issue, so `Closes #` is left N/A.

docs(vertex): Claude Code + Vertex via Headroom guide (validated) (#1180)
## Description Documents the **validated** way to run **Claude Code** against **Claude models on Google Vertex AI** with **Headroom compressing the context**. Corrects the prior review's assumption that the "Vertex-mode redirect" approach would work — Claude Code's client-side `probeVertexModel` blocks it — and documents the working **Anthropic-mode + LiteLLM `vertex_ai`** path, verified end-to-end against live Vertex quota (~22% context compression observed).

feat(proxy): hot-reload live env knobs so a reused proxy picks them up without a restart (#1090)
## Description A small class of env vars is read by the proxy **live, per request** — the output-shaper family (`HEADROOM_OUTPUT_SHAPER`, `HEADROOM_VERBOSITY_LEVEL`, `HEADROOM_EFFORT_ROUTER`, `HEADROOM_MECHANICAL_EFFORT`, `HEADROOM_VERBOSITY_AUTOTUNE`, `HEADROOM_OUTPUT_HOLDOUT`), or captured at import (`HEADROOM_INTERCEPT_READ_MIN_CHARS`). The proxy reads them from its own process environment, fixed at launch. But `headroom wrap` reuses an already-running proxy (it restarts only on startup-config drift), so a value exported *after* the proxy started silently no-op'd — e.g. `export HEADROOM_OUTPUT_SHAPER=1` had zero effect on a reused proxy on `:8787`. This PR makes those live knobs **hot-reloadable**: `headroom wrap` pushes them to the running proxy, which applies them in memory — no restart (a restart would cold-start the ML stack, drop in-flight requests, and lose CCR/router caches). _No linked issue._ ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [x] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [x] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - `headroom/proxy/runtime_env.py` (new): single source of truth registering the live knobs + a thread-safe process-global override store. `getenv()` (override-then-env) is a drop-in for `os.environ.get`; behaviour is byte-identical when no override is set. - Readers rerouted through `runtime_env.getenv`: `output_shaper.py`, the anthropic holdout read, and the ast-grep threshold (now a live read, not an import-time constant). - Proxy: loopback-only `POST /admin/runtime-env` applies overrides in memory; `/health` → `config.runtime_env` surfaces the live values so reuse is observable. - `wrap`: after attaching to a proxy (all call sites), best-effort push of the session's **explicitly-set** knobs. No-ops if nothing is set, `--no-proxy`, the proxy is unreachable, or it predates the endpoint (404). Only explicitly-set knobs are pushed, so a session never clobbers another with a default it never asked for. - Docs: README + output-token-reduction guide document the global-override caveat. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [x] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [ ] Manual testing performed ### Test Output ```text $ python -m pytest tests/test_runtime_env.py -q 16 passed $ python -m pytest tests/test_runtime_env.py tests/test_output_shaper.py -q 50 passed $ ruff check headroom/proxy/runtime_env.py headroom/proxy/output_shaper.py headroom/proxy/handlers/anthropic.py headroom/proxy/interceptors/astgrep.py headroom/proxy/server.py headroom/cli/wrap.py All checks passed! $ mypy headroom/proxy/runtime_env.py Success: no issues found in 1 source file ``` ## Real Behavior Proof - Environment: local macOS, Python 3.12 `.venv`, branch `fix/runtime-env-hot-reload` at the PR head. - Exact command / steps: ran the test suites above. The 16 new `test_runtime_env` tests exercise the registry/store, overrides reaching the shaper + the ast-grep threshold, the `POST /admin/runtime-env` apply + `/health` reflect + loopback-only 404 + 400-on-non-object, and the wrap push payload / no-op / error-swallow paths. - Observed result: 50 passed; ruff + mypy clean on the changed modules; an override set via the endpoint is read by `getenv()` at the shaper and surfaced in `/health` config. - Not tested: a literal two-terminal manual session (start a proxy, `headroom wrap` a second session, `export HEADROOM_OUTPUT_SHAPER=1`, confirm the reused proxy picks it up). The behaviour is covered by the endpoint + wrap-push integration tests, but was not exercised by hand here. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable ## Additional Notes - **Inherent caveat (documented):** overrides are global to the proxy — one process serves every attached wrapper, so the last explicit setting wins. No mechanism (restart or hot-reload) can give two sessions on one shared proxy different output-shaper settings. - **Scope:** startup-captured settings (`HEADROOM_TARGET_RATIO` etc.) are intentionally out of scope — a fresh proxy already gets them and they ride the existing `/health` config channel. - **Merge blocker:** this branch is currently **CONFLICTING with `main`** and needs a rebase/merge before it can land. - CHANGELOG.md left unchanged — releases are managed by release-please from conventional commits. |
