Hey - I've found 3 issues, and left some high level feedback:
- The
test_session_commits_bounded_by_session_tstest relies ontime.sleep(2), which slows the suite and can still be flaky; consider avoiding wall-clock sleeps by stubbing the git log timestamp or injecting a fixedsince_tsinto_project_session_commitsinstead. - The latency test
test_projector_under_500ms_on_clean_repoasserts on real wall-clock time and may occasionally be flaky on heavily loaded CI runners; you might make this more robust by loosening the bound further, conditionally skipping on very slow environments, or mocking_run_gitto simulate a healthy path while still asserting that the timeout parameter is used.

## Overall Comments
- The `test_session_commits_bounded_by_session_ts` test relies on `time.sleep(2)`, which slows the suite and can still be flaky; consider avoiding wall-clock sleeps by stubbing the git log timestamp or injecting a fixed `since_ts` into `_project_session_commits` instead.
- The latency test `test_projector_under_500ms_on_clean_repo` asserts on real wall-clock time and may occasionally be flaky on heavily loaded CI runners; you might make this more robust by loosening the bound further, conditionally skipping on very slow environments, or mocking `_run_git` to simulate a healthy path while still asserting that the timeout parameter is used.

**suggestion (performance):** Avoid redundant git calls when `cwd` is not a git repo or `git rev-parse` fails.
We currently call `_project_status`, `_project_recent_log`, and `_project_session_commits` even when `_project_branch` returns `None` (non-git directory or error). Since each call runs `git` with its own timeout, consider short-circuiting on `branch is None` and returning an empty `WorkingState` (or skipping the other projections) to preserve best-effort behavior while reducing overhead in non-repo or misconfigured environments.
Suggested implementation:
```python
def project_working_state(
cwd: Path,
recent_turns: "list[RecentTurn]",
*,
max_user_prompts: int = DEFAULT_MAX_USER_PROMPTS,
max_status_lines: int = DEFAULT_MAX_STATUS_LINES,
recent_commit_count: int = DEFAULT_RECENT_COMMITS,
) -> WorkingState:
"""Project working-state from cwd + recent turns. Pure-ish.
Pure on `recent_turns`; subprocess on `cwd`. Each git call is
# Call _project_branch once and reuse the result to avoid redundant
# git invocations. When branch resolution fails (non-git directory,
# misconfigured repo, or git error), we keep best-effort behavior by
# skipping other git-based projections instead of repeatedly calling
# git with separate timeouts.
branch = _project_branch(cwd)
```
To fully implement the optimization and short-circuiting behavior, you should also:
1. **Reuse the computed `branch` instead of re-calling `_project_branch`:**
- Find any existing calls to `_project_branch(cwd)` inside `project_working_state` and replace their usage with the `branch` variable introduced at the top of the function.
2. **Short-circuit when `branch is None` to avoid further git calls:**
- Early in `project_working_state`, after computing `branch`, add logic such as:
```python
if branch is None:
# Skip other git projections; construct an "empty" WorkingState.
# Adjust field names to match your WorkingState dataclass/constructor.
return WorkingState(
cwd=cwd,
recent_turns=recent_turns,
branch=None,
status=[],
recent_log=[],
session_commits=[],
max_user_prompts=max_user_prompts,
)
```
- The exact arguments to `WorkingState(...)` should match your existing constructor or factory methods. If `WorkingState` is created via a helper (e.g. `WorkingState.from_projections(...)`), add a corresponding "empty" or "no-git" path there instead.
3. **Guard git projection helpers with the existing `branch` value:**
- When computing status/log/commits later in `project_working_state`, make sure they are only invoked when `branch is not None`, for example:
```python
status = _project_status(cwd, max_status_lines) if branch is not None else []
recent_log = _project_recent_log(cwd, max_lines=recent_commit_count) if branch is not None else []
session_commits = _project_session_commits(cwd, recent_turns) if branch is not None else []
```
- Wire these computed values into the `WorkingState` construction as you do today.
These changes together will avoid redundant `git` subprocesses in non-repo or failing environments while preserving the current best-effort behavior.

**suggestion (testing):** Avoid wall-clock sleep in `test_session_commits_bounded_by_session_ts` to keep tests fast and non-flaky
This test uses `time.sleep(2)` and real timestamps to order commits, which makes it slower and potentially flaky on slow/overloaded hosts. Instead, make the test deterministic by controlling commit timestamps (e.g., via `GIT_AUTHOR_DATE`/`GIT_COMMITTER_DATE` or `--date`) to create two commits with known, distinct times, then pass the in-session timestamp into `RecentTurn.ts` so only that commit appears in `session_commits`.

Requesting changes — CodeQL "Module-level cyclic import" gates merge.
Three errors on the run, all the same root cause:
src/aelfrice/working_state.py:43—from aelfrice.context_rebuilder import RecentTurn(underTYPE_CHECKING)src/aelfrice/context_rebuilder.py:87—from aelfrice.working_state import WorkingState, project_working_state(top-level)
CodeQL traces TYPE_CHECKING imports for cycle detection even though they don't execute at runtime. At runtime there's no cycle (because working_state.py's side is gated by TYPE_CHECKING), so this is technically a static-analysis false positive — but it's a gating check on this repo and it'll flag every PR that touches either module.
Verification commit by commit: all 6 commits SSH-signed (G), pytest 3.12 + 3.13 green, full-suite 3206 passed / 53 skipped, discretion grep on the diff is clean, no merge commits, branch is rebased on github/main. The only blocker is CodeQL.
Two ways to clear it, ordered by churn:
-
Lift
RecentTurninto a leaf module (preferred). A newsrc/aelfrice/transcript_types.py(or_recent_turn.py) holding just theRecentTurndataclass; bothcontext_rebuilder.pyandworking_state.pyimport from it. No cycle, even statically. ~10-line move, atomic commit. -
Drop the static import on the
working_state.pyside. Replace theTYPE_CHECKINGblock with a localProtocoldescribing the fieldsworking_state.pyactually reads from a turn (role,text,ts). Smaller diff, but it duplicates the type contract — whenRecentTurngains a field thatworking_state.pyreads, the Protocol drifts.
I'd take (1). It also opens the door for any future projector that wants to consume turn data without dragging in the rebuilder.
After rebase, please re-add attn:review and the next session will pick it up.

Plumb the per-turn timestamp from the turns.jsonl schema (already specified in docs/transcript_ingest.md) through into the in-memory RecentTurn record. Additive, default None — every existing caller remains binary-compatible. The v1.5 working-state projector lands next; it uses the earliest session_id-matched ts to bound 'git log --since=<ts>' so 'recent commits authored this session' is precise rather than a 1-hour heuristic.
Pure projector that turns (cwd, recent_turns) into a WorkingState snapshot — current branch, bounded git status, last few HEAD log entries, last K user prompts, and commits authored since the latest session_id's first turn. No retrieval, no BM25, no belief extraction — these are deterministic state-of-work projections that complement the rebuilder's existing retrieval-curated belief block. Tool-call signatures are intentionally deferred (the v1.2 turns.jsonl schema does not capture them). Each git invocation runs with a 1.5s timeout and a return-empty fallback. The PreCompact hook contract is 'never block, never raise'; the projector preserves it. 20 unit tests, including a real-tmp-repo path that exercises the subprocess pipeline end-to-end.
Plumb a WorkingState through rebuild_v14() and _format_block(); emit the populated sub-block alongside <recent-turns> and <retrieved- beliefs>. The PreCompact main() projects state from cwd + recent_turns and threads it in. Best-effort: any projector exception is squashed to an empty WorkingState so the hook contract (never block, never raise) holds. The v1.7 silent-path guard now also considers WorkingState — when no belief candidates clear any lane but working-state has content, the block emits a state-of-work-only payload rather than "". Per-field omission keeps the sub-block terse: only populated fields get child tags. Six new tests cover full-emit, all-empty, missing, working-state-only, per-field omission, and XML escaping.
…C#3) AC#3 sets ≤50ms p95 in production. The test asserts a looser 500ms ceiling (10x budget) so it stays non-flaky on shared/cold CI runners while still catching a real regression — subprocess hang or missing timeout. Production budget is enforced separately via DEFAULT_GIT_TIMEOUT_S (1.5s per call).
CodeQL py/unsafe-cyclic-import flagged the working_state ↔ context_rebuilder cycle. working_state already gates its context_rebuilder import under TYPE_CHECKING; mirror that on the rebuilder side and lazy-import WorkingState + project_working_state inside _rebuild_v14_emit so runtime import order can't trigger NameError.

Posts a sticky marker comment on PRs whose additions+deletions > 200 or changed_files > 3, suggesting a split. Quiet under both thresholds and self-heals (removes the comment if a flagged PR shrinks back below the line). `size:override` label opts out for legitimate large diffs (refactors, module removals, generated code). Addresses the conflict-probability axis of #602's merge-thrash diagnosis — bigger PRs collide with more open branches and produce the rebase loops observed on PR #591 (3 force-pushes / 9 label-flips in 30 min) and #540 (4 force-pushes / 8 label-flips in 9 min). The serialization axis (label-driven merge-train) ships separately.
Closes #587 (acceptance bullets 1-3). AC#4 (eval-harness scoring) is deferred to a follow-up — see "Out of scope" below.
What lands
A post-compact
<working-state>sub-block in the rebuilder block. When the PreCompact hook fires mid-session, the block now carries a deterministic state-of-work projection alongside the existing retrieval-curated belief block:<branch>— current branch (git rev-parse --abbrev-ref HEAD)<git-status>— boundedgit status --porcelain=v1lines (default cap 50)<recent-commits>— last K HEAD log entries (default 3, format%h %s)<recent-user-prompts>— last K user prompts drawn fromrecent_turns(no extra I/O)<session-commits>—git log --since=<earliest_session_id_ts>so "what landed this session" is precise rather than a 1-hour heuristicPer-field omission keeps the block terse — only populated fields produce child tags. The whole sub-block is omitted when the projector returns an all-empty

Two items the issue's AC list mentions but this PR does not deliver, both will be filed as their own issues:

The working-state projection is deterministic and cheap (~20ms in a typical repo, ~50ms ceiling per AC). It produces a strict superset of the prior emit on every PreCompact fire that has any state-of-work to surface. Gating it behind a config knob just makes it more likely to be off when needed; the silent-path semantics (omit on empty) already give "off" behavior to non-git cwds and crashed-git environments.
