fix(copilot): normalize subscription API routing (#2441) (#2455)
## Description

PR https://github.com/headroomlabs-ai/headroom/pull/2445 added the
missing OpenCode subscription path, but the shared Copilot subscription
resolver still lets Business and Enterprise payload hosts route through
segmented `*.githubcopilot.com` domains and still drops an explicit
`GITHUB_COPILOT_API_URL` pin on two resolution paths. This follow-up
moves the final hosted-route decision back into the shared resolver,
normalizes `api.business.githubcopilot.com` and
`api.enterprise.githubcopilot.com` to the generic host by default, and
makes the explicit pin win on token exchange, explicit API token, and
Copilot-token candidate resolution. Both `headroom wrap copilot
--subscription` and `headroom wrap opencode --copilot-subscription`
inherit the same fix because they already consume the same
`CopilotSubscriptionTokenResolution.api_url`. Refs #2441.

Attribution:
https://github.com/headroomlabs-ai/headroom/pull/2445#issuecomment-5026212395
reported and narrowed the Business or Enterprise regression, and
https://github.com/headroomlabs-ai/headroom/pull/2445#issuecomment-5026863498
scoped the shared-resolver follow-up that this change implements.

## 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

- Centralize subscription hosted-route selection so explicit
`GITHUB_COPILOT_API_URL` pins win on token exchange, explicit API token,
and Copilot-token candidate resolution.
- Normalize `api.business.githubcopilot.com` and
`api.enterprise.githubcopilot.com` to `https://api.githubcopilot.com` by
default, extending the existing individual-seat normalization.
- Extend focused auth and wrapper tests so both subscription wrappers
prove the corrected shared resolver output and the private-proxy
isolation contract stays intact.

## Testing

- [x] Unit tests pass (`uv run pytest tests/test_copilot_auth.py -q`)
- [x] Unit tests pass (`uv run pytest
tests/test_cli/test_wrap_copilot.py -q`)
- [x] Unit tests pass (`uv run pytest
tests/test_cli/test_wrap_opencode.py -q`)
- [x] Unit tests pass (`uv run pytest
tests/test_cli/test_wrap_persistent.py -q`)
- [x] Linting passes (`uv run ruff check .`)
- [x] Formatting check passes (`uv run ruff format . --check`)
- [x] New tests added for new functionality when applicable
- [ ] Manual testing performed

### Test Output

```text
uv run pytest tests/test_copilot_auth.py -q -> 84 passed
uv run pytest tests/test_cli/test_wrap_copilot.py -q -> 31 passed
uv run pytest tests/test_cli/test_wrap_opencode.py -q -> 44 passed in 143.46s
uv run pytest tests/test_cli/test_wrap_persistent.py -q -> 31 passed
uv run ruff check . -> All checks passed!
uv run ruff format . --check -> 1331 files already formatted
```

## Real Behavior Proof

- Environment: Windows
- Exact command / steps: Run the focused auth, Copilot wrapper, OpenCode
wrapper, and persistent-proxy pytest files after implementing the shared
resolver change, then ask lucasp1337 to rerun the Business or Enterprise
`--copilot-subscription` scenario from PR
https://github.com/headroomlabs-ai/headroom/pull/2445#issuecomment-5026212395
on a real seat.
- Observed result: Focused auth and wrapper pytest runs passed locally,
including the enterprise-host exchange reproduction row, explicit-pin
precedence on all three producer paths, both subscription wrapper
routes, and the private-proxy isolation regression. Live Business or
Enterprise success stays behind reporter retest.
- Not tested: live Business or Enterprise tenant run

## Additional Notes

No `CHANGELOG.md` edit is needed because Headroom generates release
notes from conventional commits.

Risk for maintainers: PR
https://github.com/headroomlabs-ai/headroom/pull/641 manually validated
a Business seat against the GitHub-returned hosted domain in June on
`gpt-5.4`, so generic-by-default could affect tenants that genuinely
require a dedicated host. This follow-up keeps the documented escape
hatch intact by making `GITHUB_COPILOT_API_URL` win on every path.

Live-seat proof boundary: lucasp1337 offered to retest on a Business or
Enterprise seat in PR
https://github.com/headroomlabs-ai/headroom/pull/2445#issuecomment-5026212395.
Keep any live success claim behind that rerun.

feat(opencode): support Copilot subscription backend for headroom models (#2441) (#2445)
## Description

`headroom wrap opencode` currently routes `headroom/*` models only to
ordinary Anthropic or OpenAI backends. A user with a GitHub Copilot
subscription cannot point those `headroom/*` requests at the Copilot
seat while keeping Headroom compression and stats, even though Headroom
already has the validated subscription resolver, the proxy seed path,
and the OpenCode provider route needed to do it.

This PR adds `--copilot-subscription` to the OpenCode wrap command. It
reuses the existing Copilot subscription token resolver, passes the
validated endpoint and token seed into the existing proxy startup path,
rejects unsupported runtime modes, and treats any non-empty Copilot API
token as a private session seed so token-only sessions do not reuse a
shared proxy. The generated OpenCode provider still targets the local
proxy, and subscription secrets stay out of OpenCode config,
environment, and terminal output.

Closes #2441

## 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 wrap opencode --copilot-subscription` in
`headroom/cli/wrap.py`.
- Reuse the existing validated Copilot subscription resolver through one
small required-resolution helper shared with the dedicated Copilot
wrapper.
- Pass the resolved endpoint and token seed into `_ensure_proxy()` as
`openai_api_url`, `copilot_api_token`, `copilot_refresh_oauth_token`,
and `copilot_api_token_expires_at`.
- Reject `--copilot-subscription` with `--no-proxy`, `--prepare-only`,
and translated backends before proxy or OpenCode launch.
- Validate subscription mode before snapshotting OpenCode config, so
rejected invocations don't create stale backups.
- Scrub inherited Copilot proxy seed variables from the OpenCode child
environment.
- Treat any non-empty Copilot API token as a private session seed so
token-only sessions do not reuse shared or persistent proxies.
- Add focused OpenCode and persistent-proxy coverage for seed handoff,
guard failures, direct-token isolation, secret non-disclosure, and
unchanged non-subscription behavior.
- Leave `CHANGELOG.md` untouched because Headroom generates changelog
entries from conventional commits.

## Testing

- [x] Unit tests pass (`uv run pytest
tests/test_cli/test_wrap_opencode.py
tests/test_cli/test_wrap_persistent.py
tests/test_cli/test_wrap_copilot.py -q`, `106 passed in 136.65s`)
- [x] Linting passes (`uv run ruff check headroom/cli/wrap.py
tests/test_cli/test_wrap_opencode.py
tests/test_cli/test_wrap_persistent.py`)
- [ ] Type checking passes (`uv run mypy headroom`)
- [x] New tests added for new functionality when applicable
- [ ] Manual testing performed

### Test Output

```text
Targeted subscription tests pass: OpenCode `7 passed, 37 deselected in 0.36s`, persistent proxy `2 passed, 29 deselected in 0.34s`, and dedicated Copilot `11 passed, 20 deselected in 0.39s`. Coverage includes inherited resolver-input env scrubbing, HEADROOM_BACKEND rejection, no-backup-on-rejection, OpenCode-only scrub scoping, and private-proxy teardown on config-injection failure.
The full focused command `uv run pytest tests/test_cli/test_wrap_opencode.py tests/test_cli/test_wrap_persistent.py tests/test_cli/test_wrap_copilot.py -q` passed with `106 passed in 136.65s`. Ruff check and format check pass.
```

## Real Behavior Proof

- Environment: Windows, `uv` development environment, local CLI tests,
no live Copilot seat on this host
- Exact command / steps: run the focused OpenCode and persistent-proxy
tests with a mocked `CopilotSubscriptionTokenResolution`, then capture
the proof rows for seed handoff, direct-token isolation, guards, and
secret non-disclosure
- Observed result: Targeted subscription and proxy-seed tests pass,
including OpenCode-only resolver-input env scrubbing and private-proxy
teardown on config-injection failure; the full focused command passed
with `106 passed in 136.65s`; Ruff check and format check pass.
- Not tested: live Copilot subscription seat run on this host

tests can prove config, guard, secret, and proxy-seed behavior, but they
cannot prove a real Copilot seat on this host.
- `CHANGELOG.md` remains untouched because Headroom's release pipeline
generates changelog entries from conventional commits.

fix(wrap): make RTK opt-in (off by default) across wrap subcommands (#2344)
## Description

RTK CLI-command filtering was set up **by default** across ~16 `wrap`
subcommands (copilot, codex, aider, cursor, cline, continue, goose,
openhands, opencode, grok, omp, openclaude, vibe, …) via `if not
no_rtk:` — so users got rtk hooks / instruction injection without opting
in. `wrap claude` was the lone exception (already gated on
`--context-tool`).

This makes RTK **opt-in (off by default)** everywhere, so Headroom's own
savings are what's measured unless a user explicitly wants rtk.

Closes #

## Type of Change
- [x] Bug fix (behavior change: default flip)

## Changes Made
- **Central gate** `_rtk_opt_in()` — RTK runs only when explicitly
enabled via `--rtk` or `HEADROOM_RTK=1`. Guards the 3 RTK entry points
(`_setup_rtk`, `_ensure_rtk_binary`, `_inject_rtk_instructions`) so they
no-op by default — one small change instead of editing ~30 call sites.
- **`--rtk` opt-in flag** on all 18 tool subcommands via a shared
eager-callback option (`expose_value=False`, sets `HEADROOM_RTK=1`; no
subcommand signature changes).
- `wrap claude`'s legacy `--context-tool` still opts in (mirrored into
the gate).
- **`--no-rtk` kept** as an accepted, now-redundant no-op (back-compat).
- lean-ctx and all non-RTK behavior untouched.

## Testing
```text
pytest tests/test_wrap_rtk_opt_in.py   -> 4 passed
ruff check / format                    -> clean
mypy headroom                          -> Success: no issues found in 504 source files
```
Verified `--rtk` appears in `wrap {claude,codex,copilot} --help`;
`_rtk_opt_in()` is False by default, True with `HEADROOM_RTK=1`; entry
points no-op + write nothing when off.

## Real Behavior Proof
- Env: local `.venv`, click CliRunner.
- Steps: import wrap; assert gate default-off / env-on; assert
`_setup_rtk`/`_ensure_rtk_binary` return None and
`_inject_rtk_instructions` returns False + writes no file when not opted
in; assert `--rtk` in subcommand help.
- Observed: all pass. Not tested: a live end-to-end wrap launch (proxy
spawn).

## Notes
Part 2 of 3 (RTK opt-in). Separate PRs cover the code-graph MCP engine
and the proxy-option cleanup. No `CHANGELOG.md` edit — release-please
generates it from the PR title (per the changelog guard).

fix(opencode): Use opencode.jsonc when present (#1590)
## Description

Fix OpenCode proxy injection so it respects user configurations that use
the `.jsonc` extension, preventing Headroom from creating a duplicate
`.json` file that overrides it.

Closes #1588

## 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

- Updated `opencode_config_path` in `paths.py` to check for `.jsonc`
- Updated backup creation in `config.py` to preserve the original
extension

## 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
- [x] Manual testing performed

### Test Output

```text
N/A
```

## Real Behavior Proof

- Environment: local headroom dev
- Exact command / steps: creating a dummy
`.config/opencode/opencode.jsonc` and running `headroom wrap opencode`.
- Observed result: Headroom successfully injects into `.jsonc` and
creates a backup named `opencode.jsonc.headroom-backup`.
- Not tested: N/A

fix(wrap/opencode): unwrap removes the rtk block from AGENTS.md (#2025)
## Description

`headroom wrap opencode` injects the marker-fenced rtk guidance block —
"prefix shell commands
with `rtk`" — into **both** instruction files (`headroom/cli/wrap.py`):

```python
# wrap opencode
project_agents = Path.cwd() / "AGENTS.md"
_inject_rtk_instructions(project_agents, verbose=verbose)
global_agents = _opencode_home_dir() / "AGENTS.md"
_inject_rtk_instructions(global_agents, verbose=verbose)
```

But `unwrap_opencode` only restores the OpenCode config and cleans up
MCP servers — it never
removes that rtk block. So after `unwrap opencode`, both `AGENTS.md`
files still contain the
marker-fenced instruction, and a plain `opencode` launch keeps following
"prefix shell commands
with `rtk`" and fails once the managed rtk binary is off PATH.

`unwrap_codex` (#1421) and `unwrap_copilot` both already do this cleanup
via
`_remove_rtk_instructions`; opencode was simply never given the
equivalent — a wrap/unwrap
asymmetry.

Closes: no issue filed — found while auditing wrap/unwrap symmetry
across agents.

## Fix

In `unwrap_opencode`, after the MCP cleanup, strip the rtk block from
both files it was injected
into, mirroring `unwrap_codex`:

```python
for _agents_md in (Path.cwd() / "AGENTS.md", _opencode_home_dir() / "AGENTS.md"):
    if _remove_rtk_instructions(_agents_md):
        click.echo(f"  Removed Headroom rtk instructions from {_agents_md}.")
```

Best-effort and unconditional, matching the existing MCP cleanup and the
codex/copilot unwrap
paths. `_remove_rtk_instructions` already no-ops when the file or marker
is absent.

## Type of Change

- [x] Bug fix (non-breaking change that fixes an issue)

## Changes Made

- `headroom/cli/wrap.py`: `unwrap_opencode` removes the rtk block from
the project and global `AGENTS.md`.
- `tests/test_cli/test_wrap_opencode.py`: add
`test_unwrap_opencode_removes_rtk_from_agents_md` (wrap injects into
both, unwrap removes from both).

## Testing

- [x] New regression test added (`tests/test_cli/test_wrap_opencode.py`)
- [x] Linting/formatting clean — run with the CI-pinned `ruff==0.15.17`
- [ ] Full `pytest` deferred to CI (local-OOM reason below).

```text
$ uvx ruff@0.15.17 check headroom/cli/wrap.py tests/test_cli/test_wrap_opencode.py
All checks passed!
```

## Real Behavior Proof

- Environment: Windows 11, Python 3.10, headroom from this branch.
Importing `headroom` pulls in the torch/transformers stack and a full
`pytest` gets OOM-killed on this box, so I verified the wrap→unwrap
round-trip through the new Click-runner test (which drives the real
command) and reasoned through the marker logic; the full pytest runs on
CI.
- Exact command / steps: the added test runs `wrap opencode --no-mcp`
(asserts `_RTK_MARKER` present in both the project and global
`AGENTS.md`), then `unwrap opencode`, and asserts the marker is gone
from both.
- Observed result (the assertions the test enforces): before the fix,
`unwrap opencode` left `_RTK_MARKER` in both files; after the fix both
are clean:

```text
after wrap:   _RTK_MARKER in project AGENTS.md  ✓   _RTK_MARKER in global AGENTS.md  ✓
after unwrap: _RTK_MARKER absent (project)      ✓   _RTK_MARKER absent (global)      ✓
```

- Not tested: launching a real `opencode` binary (mocked in the test, as
the existing wrap tests do). Full local `pytest` deferred to CI (OOM,
per above).

feat(wrap): allow project RTK instruction opt-out (#2078)
## Description

Add an opt-out for project-level RTK guidance when wrapping OpenCode, so
teams can preserve an existing repository `AGENTS.md` while still
installing RTK and its global OpenCode instructions.

Closes #1980

## Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [x] New feature (non-breaking change that adds functionality)
- [ ] Breaking change
- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring

## Changes Made

- add `--no-project-rtk` to `headroom wrap opencode`
- leave the repository `AGENTS.md` untouched when requested
- continue installing RTK and its global OpenCode guidance
- cover preservation of existing team instructions

## Testing

- [x] Focused unit test passes (`pytest`)
- [x] Touched-file linting passes (`ruff check`)
- [ ] Type checking passes (`mypy headroom`) — not run
- [x] New test added for new functionality
- [ ] Manual testing performed

### Test Output

## Real Behavior Proof

- Environment: local Python test environment
- Exact command / steps: invoke the focused OpenCode wrapper test with
an existing project `AGENTS.md` and project RTK guidance disabled
- Observed result: the existing project instructions remain
byte-for-byte untouched while the global RTK guidance path still runs
- Not tested: manual OpenCode launch or the full repository test suite

## Additional Notes

The opt-out is deliberately narrow: it suppresses only the project
`AGENTS.md` mutation, not RTK installation or global OpenCode
configuration.

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.

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

## 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.

fix(cli): add explicit UTF-8 encoding to file I/O in wrap commands (#1126) (#1164)
## Description

On Windows, `Path.read_text()` and `open()` default to the system locale
encoding (cp1252, GBK, etc.) instead of UTF-8. This causes
`UnicodeDecodeError` when reading or writing instruction files that
contain multi-byte UTF-8 characters such as smart quotes or em dashes.

The RTK instructions block itself contains an em dash (U+2014, `—`), so
`_inject_rtk_instructions` crashes on any non-UTF-8 Windows locale when
writing to `.copilot_instructions`, `.clinerules`, `AGENTS.md`, or
similar hint files.

Closes #1126

## 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

- Add `encoding="utf-8"` to all bare `read_text()`, `write_text()`, and
`open()` calls in `headroom/cli/wrap.py` that handle instruction or
config files (18 call sites)
- Update test assertions in `test_wrap_hintfile_agents.py`,
`test_wrap_copilot.py`, and `test_wrap_bridge.py` to read with
`encoding="utf-8"`
- Add `test_inject_rtk_handles_utf8_content` verifying that existing
hint files with smart quotes and em dashes survive RTK injection without
crashing

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [ ] Manual testing performed

### Test Output

```text
$ python -m pytest tests/test_cli/test_wrap_hintfile_agents.py tests/test_cli/test_wrap_copilot.py tests/test_cli/test_wrap_bridge.py -v
47 passed in 1.28s
```

## Real Behavior Proof

- Environment: Windows 11 China (GBK locale), Python 3.11, headroom main
(f03e77b)
- Exact command / steps: python -m pytest
tests/test_cli/test_wrap_hintfile_agents.py -v (on GBK Windows)
- Observed result: Before fix,
test_prepare_only_injects_rtk_into_hintfile fails with
UnicodeDecodeError 'gbk' at position 283 (the em dash in RTK block).
After fix, all 12 hintfile tests pass including new UTF-8 round-trip
test.
- Not tested: no manual `headroom wrap copilot` run against a real
Copilot installation

## Additional Notes

This is the same class of bug reported in #733 (GBK config.toml
corruption). This PR fixes the `wrap.py` call sites; other modules
(`learn/analyzer.py`, `install/providers.py`) have the same pattern and
could benefit from the same treatment in a follow-up.

ci: restore green lint (reformat for ruff 0.15.17, fix mypy no-any-return, pin linters) (#1295)
## Description

The CI lint job (`ruff check .` → `ruff format --check .` → `mypy
headroom`) was red on `main`
and therefore on every open PR, for two unrelated reasons that the early
ruff failure was masking:

1. **ruff**: the lint job installs `ruff` unpinned, and ruff 0.15.17
began enforcing import-block
sorting (`I001`) and formatting that older ruff accepted → `ruff check
.` / `ruff format --check .`
   fail on files nobody touched.
2. **mypy**: `headroom/providers/opencode/config.py` had two `return
json.loads(...)` statements in
a function declared `-> dict[str, Any]`; `json.loads` is typed `Any`, so
`mypy headroom` fails
with `no-any-return` (reproduced on mypy 1.20.2 — not a version-specific
quirk).

This restores a green lint baseline and pins both linters so a future
release can't silently break
CI again.

## Type of Change

- [x] Bug fix (non-breaking change that fixes an issue)

## Changes Made

- `.github/workflows/ci.yml`: pin `ruff==0.15.17` and `mypy==1.20.2` in
the lint job.
- Applied `ruff check --fix .` (6 `I001` import-sort fixes) and `ruff
format .` (10 files) across
  the repo — import ordering and whitespace only, no behavior change.
- `headroom/providers/opencode/config.py`: narrow both
`_parse_json_loose` return sites with an
`isinstance(parsed, dict)` guard, so the `dict[str, Any]` annotation is
true at runtime
(non-dict JSON falls back to `{}`) and mypy's `no-any-return` is
resolved.

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`, `ruff format --check .`, `mypy
headroom --ignore-missing-imports`)

### Test Output

```text
$ python -m ruff check .
All checks passed!

$ python -m ruff format --check .
913 files already formatted

$ python -m mypy headroom/providers/opencode/config.py --ignore-missing-imports
Success: no issues found in 1 source file

$ python -m pytest tests/test_providers_opencode_config.py -q
37 passed
```

## Real Behavior Proof

- Environment: Windows 11, Python 3.13, ruff 0.15.17, mypy 1.20.2,
branch ci/fix-ruff-lint off
  headroomlabs-ai/main
- Exact command / steps: reproduced the red lint (latest ruff: 6 `I001`
+ 10 unformatted files;
the mypy failure was read from the #1295 CI lint log —
`config.py:125,133 no-any-return`, and
re-confirmed locally on mypy 1.20.2). Applied the ruff auto-fix/format,
added the dict guard,
  pinned both linters, and re-ran each lint step.
- Observed result: `ruff check .` → "All checks passed!"; `ruff format
--check .` → "913 files
already formatted"; `mypy` on the fixed file → "Success: no issues
found"; full `mypy headroom`
reports only Unix `fcntl` attributes that don't exist on this Windows
box (present on the Linux
CI runner, where the prior run showed exactly the two now-fixed errors).
37 opencode-config
  tests pass.
- Not tested: did not run the full OS/Python test matrix — the change is
formatting + two CI
dependency pins + a two-line type-narrowing guard, with no runtime
behavior change for dict JSON.

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.
