- **code:** fix two `CodeAwareCompressor` AST-reassembly bugs: an exported JS/TS function or class (`export function foo() {`) produced a duplicated `export export` keyword and invalid syntax, because line-based node slicing (used to preserve indentation) pulled in the preceding `export` sibling's text on top of the `export_statement` handler's own prefix reconstruction. Separately, in every supported language, a doc comment immediately above a top-level function, class, or type was detached from its declaration during extraction and re-emitted in a cluster at the end of the compressed output instead of staying attached to what it documents.
|

- * **proxy:** Buffered upstream responses containing a `server_tool_use` (or any other unrecognized Anthropic content block) no longer turn a fully-generated response into an HTTP 502. `StreamingMixin._response_to_sse` raised `ValueError` on unknown block types after the entire upstream generation had already been buffered, so a slow-but-successful response failed and the client retried the whole multi-minute request. Unknown blocks are now emitted verbatim in `content_block_start` (following the existing redacted_thinking` pattern), so `server_tool_use`, `server_tool_result`, `mcp_tool_use`, and future block types round-trip ([#1806](https://github.com/headroomlabs-ai/headroom/issues/1806)).

* **codex:** detect ChatGPT auth from id_token claims so wrap/init emit requires_openai_auth ([#3212](https://github.com/headroomlabs-ai/headroom/issues/3212)) ([2f81fa5](https://github.com/headroomlabs-ai/headroom/commit/2f81fa5931ddf233b908103f25c614b5a6b7e33b))
|
||||
* **doctor:** report project-scoped Claude routing instead of a false negative ([#3213](https://github.com/headroomlabs-ai/headroom/issues/3213)) ([8f3e33a](https://github.com/headroomlabs-ai/headroom/commit/8f3e33a00ea377403497b600841c03344d0c1cd8))

|

## Server-managed settings unavailable through custom ANTHROPIC_BASE_URL
|
||||
|
||||
**Symptom**: Settings pushed from **Admin Settings > Claude Code > Managed settings** in the claude.ai console (server-managed settings) don't apply to sessions running through Headroom, even though they apply fine without the proxy.
|
||||
|
||||
**Cause**: This is a Claude-side gate, not a Headroom limitation. Per Anthropic's docs, server-managed settings require a direct connection to `api.anthropic.com`; if `ANTHROPIC_BASE_URL` is set to any non-default host — which is exactly what wrapping via Headroom does — Claude Code skips the settings fetch entirely for that session. The request never reaches Headroom, so there is no endpoint for Headroom to implement or proxy.
|
||||
|
||||
This is separate from the OS-level `managed-settings.json` file (macOS `/Library/Application Support/ClaudeCode/`, Linux `/etc/claude-code/`, Windows `C:\Program Files\ClaudeCode\`): that file is read straight from local disk at startup and is unaffected by `ANTHROPIC_BASE_URL` or Headroom. If that file isn't taking effect, the cause is unrelated to proxying (path, permissions, or JSON syntax) — check `claude --debug-file <path>` and search the log for `Remote settings`.
|
||||
|
||||
**Fix**: None available on the Headroom side — this is an intentional Anthropic security boundary (a proxy in the path could otherwise forge org policy). If your org relies on server-managed settings, deploy the same policy as [endpoint-managed settings](https://code.claude.com/docs/en/settings#settings-files) (MDM profile, Windows registry, or a local `managed-settings.json`) instead, since those are read locally and unaffected by proxying.
|
||||
|
||||
See [Server-managed settings platform availability](https://code.claude.com/docs/en/server-managed-settings#platform-availability) and [issue #3074](https://github.com/headroomlabs-ai/headroom/issues/3074).

|
||||
## Compression Too Aggressive
|
||||
|
||||
**Symptom**: LLM responses are missing information that was in tool outputs.

"""Session-turn engine — the single cache-management brain for both modes.
|
||||
|
||||
One conversation turn, from the cache's point of view, is always the same
|
||||
three-step dance regardless of who owns the upstream call:
|
||||
|
||||
1. **Prepare** (:func:`prepare_turn`): decide how many leading messages are
|
||||
frozen, mark the stable prefix, and swap previously-computed compressed
|
||||
bytes into the working copy (``apply_cached`` — "Zone 1").
|
||||
2. Run the compression pipeline over the prepared input (owned by the
|
||||
caller: the proxy handlers wrap it in background/cold-start/backpressure
|
||||
orchestration, the sidecar path runs it inline on the executor).
|
||||
3. **Finalize** (:func:`finalize_turn`): replay last turn's exact
|
||||
previously-forwarded/returned prefix over any residual drift the pipeline
|
||||
introduced (``overlay_cached_prefix``), so the bytes that leave the
|
||||
process are byte-identical to what the provider already cached.
|
||||
|
||||
Historically the proxy request handlers (anthropic + openai token mode) and
|
||||
the sidecar ``/v1/compress`` session path each carried their own inline copy
|
||||
of steps 1 and 3. This module is the shared implementation: a
|
||||
cache-management fix landed here reaches BOTH modes at once.
|
||||
|
||||
Freeze policies
|
||||
---------------
|
||||
|
||||
The one deliberate behavioural difference between the modes lives in step 1,
|
||||
and it is a *policy parameter*, not a fork of the code:
|
||||
|
||||
``FREEZE_POLICY_CONFIRMED_CLAMP`` — ``min(tracker_frozen, cache_count)``.
|
||||
The proxy sees the provider's responses, so ``tracker_frozen`` is the
|
||||
provider-confirmed cached prefix (from ``cache_read_input_tokens``).
|
||||
Freezing is clamped by BOTH bounds: never past what the provider
|
||||
actually has cached (freezing more would forgo compression of content
|
||||
that is not yet cache-protected — the #327 posture), and never past what
|
||||
the local cache can byte-replay (freezing a message whose entry was
|
||||
evicted would pass through raw original bytes).
|
||||
|
||||
``FREEZE_POLICY_REPLAYABLE`` — ``max(cache_count, explicit_frozen or 0)``.
|
||||
Freeze everything the local cache can byte-replay. Used by callers with
|
||||
no provider-confirmed count to clamp against: the sidecar ``/v1/compress``
|
||||
endpoint (it never sees the provider's response — whatever it previously
|
||||
RETURNED is the provider's cache contract, so every already-returned
|
||||
message must come back byte-identical), and the OpenAI proxy token path
|
||||
(its tracker feeds cache mode, not token mode). Recompressing an
|
||||
already-returned message — even into a *smaller* form — is a bust: the
|
||||
drift was observed in practice, and ``overlay_cached_prefix``'s
|
||||
non-inflation guard cannot repair a shrunken form (replaying the larger
|
||||
original bytes would "inflate" the candidate). Freezing the entire
|
||||
locally-replayable prefix eliminates that recompression outright.
|
||||
Over-freezing relative to the provider's real cache only forgoes tail
|
||||
compression; it can never bust. An explicit ``frozen_message_count``
|
||||
from the caller still wins when larger — the caller may know more about
|
||||
the provider cache than local state does.
|
||||
|
||||
Why the Anthropic proxy path cannot simply adopt the replayable posture: its
|
||||
provider-confirmed clamp deliberately KEEPS not-yet-cached content
|
||||
compressible, and its overlay inputs (tracker snapshots) are refreshed on
|
||||
every response, so drift repair is reliable there. Each posture is correct
|
||||
for the information its mode actually has.

Covers the two eviction paths on ``HeadroomProxy._get_compression_cache``:

* capacity eviction must be LRU by *access* (a busy long-lived session
|

survives; the idlest session goes), not FIFO by creation, and

* the lazy idle-TTL sweep must reclaim sessions whose provider prompt

"""Regression tests for the "compression garbled the output" report.
|
||||
|
||||
A user's model called compressed subagent output "too garbled to use" and
|
||||
burned CCR retrievals to reconstruct it — one retrieval returned nothing
|
||||
but the harness sanitizer banner. Root causes, each pinned here:
|
||||
|
||||
1. ``split_into_sections`` typed any bracket-balanced text as JSON_ARRAY
|
||||
(no ``json.loads`` validation), so the bracket-delimited harness
|
||||
banner entered the structured compressors and, via their fallback
|
||||
chain, lossy Kompress.
|
||||
2. Kompress had a 10-word floor: it lossy-compressed a 33-word banner,
|
||||
"saving" 8 words while appending a ~20-word retrieval marker.
|
||||
3. SmartCrusher's lossless CSV+schema render replaces a whole array with
|
||||
one JSON *string*; spliced into mixed text, the model saw a
|
||||
quote-wrapped single line with ``\\n`` as two-character escapes.
|
||||
4. ``ensure_ascii=True`` defaults at model-visible boundaries turned
|
||||
real unicode (Codex output is full of it) into ``\\uXXXX`` soup.
|
||||
5. Kompress stored word counts in the store's *item count* fields and
|
||||
said "items" in its marker — a 33-word banner retrieved as
|
||||
"original_item_count: 33" reads as a mangled 33-item structure.

"""Regression tests: file reads over the OpenAI Responses API path must stay verbatim.
|
||||
|
||||
Copilot CLI (and other Responses-native harnesses) read files two ways:
|
||||
|
||||
1. A first-class ``view`` tool (the Copilot equivalent of Claude Code's ``Read``)
|
||||
whose output is raw file content the model will byte-patch against.
|
||||
2. Shell reads through ``bash`` (``cat``/``nl``/``sed -n`` …), which the
|
||||
chat/Anthropic path protects via ``HEADROOM_PROTECT_READS`` read-command
|
||||
detection in ``ContentRouter``.
|
||||
|
||||
The Responses compression-units path historically protected neither: only
|
||||
``DEFAULT_EXCLUDE_TOOLS`` names were honored, and ``HEADROOM_PROTECT_READS``
|
||||
was never consulted. Lossy (Kompress) compression of a fresh file read garbles
|
||||
exactly the bytes the model needs for line-precise edits, forcing re-reads
|
||||
(turn inflation) — the harm read protection exists to prevent.

"""A Claude turn routed to GitHub Copilot must reach it authenticated, and be

Copilot serves Claude models from its Anthropic surface (``/v1/messages``) on

the same host as its OpenAI surface, so the resolved Anthropic target can be a

applied only by ``_stream_response``. The buffered arm sends through
|
||||
``_retry_request``, which forwards headers untouched, so the request carried
|
||||
no minted token and no ``Copilot-Integration-Id``.
|
||||
- **Attribution.** ``build_copilot_upstream_url`` is the only place the
|
||||
routed-to-Copilot flag is set, and the buffered arm built its URL by
|
||||
f-string — so ``emit_request_outcome`` never relabeled the provider and the

turn showed as "anthropic".
|
||||
|

Both are pinned here at the ``_retry_request`` seam: the URL that was built, the
