From b22900a409bea7aa5688ca7f33ecf88aeb95ee29 Mon Sep 17 00:00:00 2001 From: WulfForge Date: Wed, 29 Apr 2026 12:26:16 -0400 Subject: [PATCH 1/3] =?UTF-8?q?feat:=20preflight=20telemetry=20capture=20l?= =?UTF-8?q?oop=20pieces=201=E2=80=934=20(v0.15.0,=20#65)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds opt-in local-only preflight telemetry β€” captures preflight events and downstream tool engagement for failure-mode triage. Default off; hashed by default; raw via separate env var. New module: preflight_telemetry.py - Salt at ~/.bicameral/salt (mode 0o600), per-install, race-safe init - hash_topic, hash_file_paths (order-independent set hash) - new_preflight_id (UUIDv4) - write_preflight_event, write_engagement (JSONL append, mode 0o600) - _maybe_rotate (50MB / 30 days, keeps last 5) preflight_id plumb-through: - PreflightResponse, LinkCommitResponse, BindResponse, RatifyResponse gain optional preflight_id: str | None field - update.py dict returns also gain preflight_id key (11 sites) - server.py inputSchema for affected tools accepts optional preflight_id Pieces 5 (SessionEnd reconciliation skill) and 6 (triage CLI) are deferred to follow-up plans #65-pt2 and #65-pt3.

Format loosely follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/). +## v0.15.0 β€” Preflight telemetry capture loop (pieces 1–4) β€” built via [QorLogic SDLC](https://github.com/MythologIQ-Labs-LLC/qor-logic) + +First slice of the failure-mode triage workflow from #65. Adds a local-only, +**default-off** capture loop that records bicameral.preflight events plus +downstream tool engagement, attributable per-call via a new ``preflight_id``. +The data is for self-triage of false fires / silent misses; it never leaves +the user's machine and is not part of the existing PostHog relay path. + +### Added + +- **New module: `preflight_telemetry.py`** (top-level, sibling of + `telemetry.py` β€” they are independent capture systems). Provides: + - `_get_or_create_salt()` β€” per-install salt at `~/.bicameral/salt`, + `os.urandom(32)`, mode `0o600` on POSIX. Race-safe init: `os.O_EXCL` + create with a `FileExistsError` fallback that reads the winner's + bytes (audit MF1 inline fix). + - `hash_topic(topic)` and `hash_file_paths(paths)` β€” salted SHA-256 + truncated to 16 hex chars (~64 bits). `hash_file_paths` is + order-independent so `["a.py","b.py"]` and `["b.py","a.py"]` collide + by design. + - `new_preflight_id()` β€” fresh UUIDv4. + - `write_preflight_event(...)` β€” JSONL append at + `~/.bicameral/preflight_events.jsonl`, mode `0o600`. + - `write_engagement(...)` β€” JSONL append at + `~/.bicameral/engagements.jsonl`, mode `0o600`. Falls back to + subset-match attribution against recent preflight events when no + explicit `preflight_id` is supplied. + - `_maybe_rotate(path)` β€” rotates at 50 MB or 30 days, keeps the most + recent 5 rotations. Uses `os.replace` (atomic on Windows + POSIX). +- **`preflight_id` plumb-through** β€” new optional `str | None` field on + `PreflightResponse`, `LinkCommitResponse`, `BindResponse`, and + `RatifyResponse`. The `update.py` handler returns dicts and now adds a + `preflight_id` key to every return shape (audit S3 β€” 11 sites). Each + affected handler (`handle_link_commit`, `handle_bind`, `handle_ratify`, + `handle_update`) gains a keyword-only `preflight_id: str | None = None` + parameter. +- **MCP tool inputSchema** β€” `preflight_id` (optional string) added to + `bicameral.preflight`, `bicameral.link_commit`, `bicameral.bind`, + `bicameral.update`, `bicameral.ratify`. Existing skills that don't pass + it keep working unchanged. +- **Tests** β€” `tests/test_preflight_telemetry.py` (19 cases covering + salt, hash, writers, rotation, race-loser MF1) and + `tests/test_preflight_id_plumbing.py` (9 cases covering the response + field on each affected handler). + +### Privacy stance + +- **Opt-in.** Default is OFF. Set `BICAMERAL_PREFLIGHT_TELEMETRY=1` to + capture; unsetting it makes every writer a no-op. +- **Hashed by default.** Topic and file_paths are stored as 16-char + salted SHA-256 prefixes. Set `BICAMERAL_PREFLIGHT_TELEMETRY_RAW=1` to + additionally store plaintext β€” separate, explicit opt-in. +- **`surfaced_ids` are written raw.** They are opaque ledger + `decision_id` strings, already non-PII. Hashing them would defeat the + triage join with `failure_review.jsonl` (the only useful join). + Documented as an invariant in the module docstring. +- **Local-only.** All files live under `~/.bicameral/`, mode `0o600`. + Data never leaves the machine; this is a separate path from the + PostHog relay in `telemetry.py`. +- **Bounded retention.** 50 MB rolling cap per file; 30-day mtime + ceiling; keep last 5 rotations. + +### Out of scope (deferred to follow-up plans) + +- **Piece 5 β€” SessionEnd reconciliation skill** (#65-pt2). Reads the + JSONL files, classifies entries as `suspected_miss` / + `suspected_false_fire` / `normal`, writes `failure_review.jsonl`. +- **Piece 6 β€” Triage CLI + redaction** (#65-pt3). `bicameral-mcp triage` + CLI for labeling failure rows; promotion to + `tests/eval/real_dataset.jsonl` requires explicit redaction. + +### Closes + +#65 (pieces 1–4 only β€” pieces 5–6 tracked separately) + ## v0.14.0 β€” Local-only telemetry counters + usage summary + first-boot consent β€” built via [QorLogic SDLC](https://github.com/MythologIQ-Labs-LLC/qor-logic) Privacy-first observability foundation.
