Commit, push, PR; transcript + handoff. + +--- + +## Turn-by-turn arc + +### Arc 1 — Orientation + a double session-ID claim + +Read the Phase 1 doc, the proposal, and the session protocol. Ran +`claim-session-id.sh` and — through a tool-batching mistake (a sandboxed call +that was assumed to have failed had actually succeeded) — **claimed 0049 AND +0050**. Kept **0049** as the real session and immediately finalized **0050** as +an aborted stub (start == end), published via `publish-transcript.sh`, so the +shared registry shows no phantom live session for 0050. + +Confirmed neither design PR was merged (see pre-state). + +### Arc 2 — Codebase survey + design decision + +Surveyed the flotilla codebase (Click CLI; `registry.py` deployment record; +`pin.py` Gitea raw read; `ssh.py` IAP-SSH with the §11.6 gcloud guard; +`webhooks.py`/`gitea.py` as the closest precedent for a read-only "inspect + +report drift" verb; `deploy.py` for conventions). + +Key decision: the deployment record had **no field naming the rfc-app *source* +repo** — it only knew the content/pin repo (`ben/ohm-rfc`). The Phase 1 spec +(§2.1/§2.2) reads `requirements.txt`/`package-lock.json` from the rfc-app repo +at the pinned tag via Gitea raw. Per the two-layer rule (CLAUDE.md), that +coordinate must live in the record, not be hardcoded. So added a nullable +`app_source_repo` column (migration 007), mirroring how 006 added +`gcloud_config` — inert-until-set, host reused from `pin_source_host`. + +### Arc 3 — The build + +Worked in an isolated git worktree (memory: parallel sessions do hands-on git +in a worktree; there were stale in-progress sessions in the shared repo). +EnterWorktree branched off `origin/main` → branch +`worktree-session-0049-patchwatch-phase1`. + +Shipped: +- `ohm_rfc_app_flotilla/audit.py` (~760 lines): `Finding`/`ScannerError`/ + `AuditReport` schema (§3); `classify()` lane router with tunable + `FAST_LANE_SEVERITY="high"` (§4); `normalize_severity` (GHSA words + CVSS + numbers → 4 bands); `fetch_kev` (CISA KEV → set of CVE IDs); `osv_results_to_findings` + (+ KEV join on aliases); `run_osv_scanner` (subprocess, exit 1 = vulns found, + not error); Gitea raw read at a ref; four scanners (`scan_py_app`, + `scan_node_app`, `scan_os`, `scan_flotilla`) each degrading to a + `scanner_error` rather than crashing; `run_audit` orchestrator with all IO + dependency-injected. +- `migrations/007_app_source_repo.sql` + `registry.py` field plumbing + + `cli.py` `deployment add/update/show --app-source-repo`. +- `cli.py` `flotilla audit` verb: `--json`, `--layer`, `--min-severity`, + `--fail-on` (default advisory/exit 0, like `pin check`/`webhook check`). +- `tests/test_audit.py`: classifier truth-table, severity normalization, OSV→ + Finding + KEV join, apt parsing, every scanner (happy + degraded), `run_audit` + orchestration, and CLI (`--json`/`--fail-on`/`--min-severity`/`--layer` + + exit codes). All network/SSH/subprocess/clock mocked. + +### Arc 4 — A long fight with delayed tool output + +For a large stretch the harness rendered tool results in **severely delayed +batches** (calls returned empty for many turns, then a big flush dumped +everything at once). This cost a lot of turns: re-issuing reads, re-running +pytest, and confirming the worktree path. One concrete casualty — an early +batch was **cancelled** when a `git reset --hard origin/main` hit a permission +denial and cascaded (so a first round of writes/edits had to be redone). The +worktree was already at `origin/main`, so the reset was unnecessary anyway. +Eventually learned that launching a background task (its completion +notification) reliably flushed the backlog. No work was lost; the record keeps +the friction in per the no-curation rule. + +### Arc 5 — Verification, doc-sync, push + +First green run: **270 passed, 1 failed** — and the failure was a bug in the +*test*, not the code (`test_run_audit_pin_failure_degrades` asserted an OS +*finding* existed, but the shared stub's fake VM reports nothing upgradable, so +the OS scanner correctly returned zero findings). Fixed the assertion to "OS/ +flotilla scanned without error" → **271 passed**. `flotilla audit --help` +renders correctly. + +Committed `b2a9a11` (code + CHANGELOG + VERSION 1.5.0 + pyproject), pushed to +`session-0049/patchwatch-phase1-audit`. Then synced the binding docs (SPEC +§12.1 line, §12.4 audit section, §13.10 record field; operator-guide §2.6 + §4; +fixed the code/CHANGELOG cross-refs §12.2 → §12.4) in a second commit and +pushed. + +--- + +## Cut state (end of session) + +| | | +| --- | --- | +| flotilla branch | `session-0049/patchwatch-phase1-audit` pushed to origin (off `main` `5f1689f`) | +| flotilla `main` | unchanged at `5f1689f` (v1.4.0) — not merged this session | +| VERSION | 1.5.0 (on the branch) | +| tests | 271 passed | +| OHM live | untouched (no deploy; v1.5.0 is operator-tool code, no redeploy needed) | +| ohm-rfc pin | untouched | +| design branches | flotilla `patchwatch/proposal-docs` + ohm-rfc `roadmap/43-patchwatch` — STILL UNMERGED | + +| Item | Status | +| --- | --- | +| Patchwatch Phase 1 radar (`flotilla audit`, ROADMAP #43) | ✅ built, tested, pushed (PR not yet opened) | +| Patchwatch Phase 2 (OS unattended-upgrades) | ⏸ not started (independent of Track Δ) | +| Patchwatch Phase 3 (mitigation lane / kill-switch) | ⏸ needs rfc-app coordination | +| Patchwatch Phase 5 (auto-initiate tier) | ⏸ deliberately not built — needs Track Δ + cloud identity | + +--- + +## §19.2 / follow-up candidates surfaced + +1. **Private rfc-app repo token.** The app scanners read the rfc-app source via + public Gitea raw (like `pin.py`).
