Authored via QorLogic SDLC (plan → audit → implement → substantiate). Builds on the dev branch post-merge with main's v0.13.x telemetry refactor. Closes #39 — Local-only counter sink at ~/.bicameral/counters.jsonl. Records only {tool_name, delta=1, ts}; mode 0o600 on POSIX; thread-safe; no network egress. Always-on alongside the network relay (counters are local introspection, distinct from outbound telemetry). Kill-switch: BICAMERAL_LOCAL_COUNTERS=0. New module local_counters.py with increment(tool_name) and read_counters() API. Closes #42 — bicameral.usage_summary MCP tool. Aggregates ingest/bind call counts (from #39's counters file) plus decision counts by status (from ledger) and cosmetic-drift percentage (from compliance_check verdicts) over a configurable window. Returns counts and floats only — no event rows, no user content. New module handlers/usage_summary.py. Adjacent to #39: consent.py — owns ~/.bicameral/consent.json, telemetry_allowed() predicate (single source of truth gating the relay), and notify_if_first_run() non-blocking notice. Marker has acknowledged_via field distinguishing "wizard" from "first_boot_notice" for future audit. POLICY_VERSION constant re-fires the notice for everyone if the telemetry policy ever changes. telemetry.send_event: - now uses consent.telemetry_allowed() as the single gating predicate - always increments the local counter before the relay path (wrapped in try/except — failure cannot affect the caller or the relay) setup_wizard._select_telemetry: - writes the consent marker on every answer (wizard, non-interactive default, both) - raises OSError on marker write failure — guarantees a "no" answer cannot silently leave telemetry on server.serve_stdio: - calls consent.notify_if_first_run() once at startup, never blocking CI: BICAMERAL_SKIP_CONSENT_NOTICE=1 added to test job env. tests/conftest.py: session-scoped autouse fixture reroutes ~/.bicameral/ to a per-session tmp dir; stdlib only.

cb682c4d4646093220f7bb07616e305c86c2a400 Mon Sep 17 00:00:00 2001 From: Kevin Knapp Date: Tue, 28 Apr 2026 17:06:45 -0400 Subject: [PATCH 3/5] fix(#74): make events.writer cross-platform (POSIX fcntl + Windows msvcrt) (#80) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Issue #74: ``events/writer.py:16`` had a top-level ``import fcntl``, which is Unix-only. On Windows the import failed at module load, which collapsed any test session that imported (directly or transitively) ``events.writer`` — including all 17 ephemeral authoritative tests and a long tail of ingest-using tests. Fix: - Replace the top-level ``import fcntl`` with a platform-conditional block that imports either ``fcntl`` (POSIX) or ``msvcrt`` (Windows) and defines ``_lock_exclusive`` / ``_unlock`` helpers with matching semantics. - POSIX path uses ``fcntl.flock(LOCK_EX/LOCK_UN)`` — unchanged behaviour. - Windows path locks byte 0 with ``msvcrt.locking(LK_LOCK/LK_UNLCK, 1)`` so concurrent writers serialize on a shared mutex byte. The actual append happens via ``open(..., "ab")`` which on Windows seeks to EOF per write — the byte-0 lock is the serialization primitive, not a region lock. - Both branches use ``# pragma: no cover`` for the inactive platform. Tests: - ``tests/test_event_writer.py`` — new, 7 tests: - module imports cleanly on the current platform (regression for the original ImportError) - lock helpers exist and are callable - ``write()`` produces a parseable JSONL line - consecutive writes release the lock (would deadlock if leaked) - locking byte 0 on a previously-empty file works (Windows msvcrt edge case) - platform-specific dispatch checks (``test_windows_uses_msvcrt`` / ``test_posix_uses_fcntl``, mutually skipped) Verified on Windows: 6/6 active tests pass. Ephemeral authoritative suite went from 0/17 collectable to 15/17 passing (the remaining 2 are pre-existing V2 promotion gaps unrelated to fcntl). No POSIX behaviour change. --- events/writer.py | 51 +++++++++++++-- tests/test_event_writer.py | 126 +++++++++++++++++++++++++++++++++++++ 2 files changed, 173 insertions(+), 4 deletions(-) create mode 100644 tests/test_event_writer.py diff --git a/events/writer.py b/events/writer.py index b7a26493..fc78965d 100644 --- a/events/writer.py +++ b/events/writer.py @@ -13,18 +13,61 @@ from __future__ import annotations -import fcntl import json import logging import subprocess +import sys from datetime import datetime, timezone from pathlib import Path -from typing import Any +from typing import Any, IO from pydantic import BaseModel, Field logger = logging.getLogger(__name__) +# Cross-platform advisory file lock for the event JSONL writer. +# +# Background: this module appends one line per event to a per-author +# ``.bicameral/events/{email}.jsonl`` file.

Changes: - ledger/adapter.py: add `apply_ratify(decision_id, signoff)` and `apply_supersede(new_id, old_id, ...)` to SurrealDBLedgerAdapter. Both methods are idempotent so the materializer can replay them safely. They wrap the existing inline UPDATE + project + supersedes helpers — no behavioral change for solo mode. - events/team_adapter.py: add wrappers that emit `decision_ratified.completed` and `decision_superseded.completed` events before delegating to the inner adapter. Event payloads carry `canonical_id` (UUIDv5 from description + source_type + source_ref) so cross-author replay can resolve to the peer's local row even though SurrealDB-generated decision ids are per-DB. - events/materializer.py: replay cases for the two new event types. Each looks up the local decision row by canonical_id; warns and skips if not found (out-of-order replay across authors). - handlers/ratify.py: route through `ledger.apply_ratify` instead of inline UPDATE + project_decision_status + update_decision_status. Pre-write idempotency check (early return when state already matches) is unchanged. - handlers/resolve_collision.py: route through `ledger.apply_supersede` for the supersede branch. Edge creation + frozen-signoff merge moves into the adapter so it's reachable from replay. - ledger/queries.py: new `get_canonical_id(client, decision_id)` and `find_decision_by_canonical_id(client, canonical_id)` helpers. Tests: - tests/test_team_event_replay.py (new) — three round-trip tests: ratify, supersede (with edge replay), and ingest regression. Each ingests through team adapter A, then connects a fresh team adapter B pointing at the same JSONL log + a fresh memory:// inner DB and a fresh watermark. Asserts state in B matches what A wrote. - tests/test_preflight_id_plumbing.py — updated the ratify mock to match the new `ledger.apply_ratify` shape. Out of scope (deferred to future PRs): compliance_checked event (Phase 4 uses CHANGEFEED), CHANGEFEED extension to code_subject / subject_identity / binds_to / code_region (schema migration), SHA256 chain (strictly v1). Closes part of #97. Co-Authored-By: Claude Opus 4.7 (1M context) (cherry picked from commit e6d4b8ffe71f6f6f80e18f77ac8a3ed7067f3922) Adaptation: ledger/queries.py — kept only #97's two new helpers (get_canonical_id, find_decision_by_canonical_id); auto-merge had inadvertently bundled the #77 update_decision_level block (PR #107, decision_level classifier, v0.16.0) which is a missing prerequisite on triage and not part of e6d4b8f's actual diff for this file Adaptation: handlers/ratify.py — kept only e6d4b8f's import-list change (drop update_decision_status); dropped the auto-merged preflight_telemetry import which is a missing prerequisite on triage (#65 preflight telemetry capture loop) and not referenced by the cherry-picked body Skip: tests/test_preflight_id_plumbing.py — kept triage's prior deletion of this file;

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 0a — Decompose server.py:cli_main (92 LOC → 15 LOC orchestrator + _register_subparsers (16 LOC) + _dispatch (29 LOC)). Razor-compliant. Phase 0 — Promote cli/branch_scan.py:_invoke_link_commit to shared cli/_link_commit_runner.py module. Pure refactor under existing test_branch_scan_cli.py coverage. Phase 1 — Register link_commit CLI subcommand: - cli/link_commit_cli.py (29 LOC) — JSON-to-stdout default, --quiet flag, always exits 0 (graceful skip on no-ledger or handler error). - server.py — subparser registration in _register_subparsers + dispatch branch in _dispatch. - tests/test_link_commit_cli.py (6 tests) — argparse defaults, output shape, --quiet, no-ledger graceful skip, handler-exception graceful skip. Phase 2 — Harden post-commit hook: - setup_wizard.py:_GIT_POST_COMMIT_HOOK now writes stderr to ${HOME}/.bicameral/hook-errors.log (was /dev/null), surfaces a one-line summary on stderr, always exits 0. > truncates the file on each run so successful commits auto-clear stale errors. F-2 remediation per audit v2. - tests/test_hook_command_registration.py (3 tests) — smoke that walks every bicameral-mcp in installed hooks and asserts CLI registration + dispatch coverage. Original #124 bug class is now caught at PR time. Phase 3 — CHANGELOG [Unreleased] Fixed entry. Validation: 20 passed, 1 skipped (Windows chmod). ruff check + format + mypy clean. Manual smoke: link_commit --help renders. Plan v2 PASS at META_LEDGER #21 (chain 86225d49). Implementation sealed at META_LEDGER #22 (chain e83d674c). Closes #124.
