rdmsm4x-changelog-20260925-1021-audit-reachability-fix-estate-relevelled

Run 2026-09-25 10:11:18 → 10:21 EDT on rdmsm4x by claude@rdmsm4x/dev-c5 (cli 65c5e356), resumed by resume_agent_sessions.zsh after the 22:57 fleet reboot. Timestamps from date. Budget proceed — Anthropic 7d 0% after the weekly reset, 5h 2%; OpenAI 26%. Inline, no subagents.

One line: last night's dedupe fix is confirmed working in production, the repos-unpushed check no longer depends on who last fetched, and the estate is level again — 21 repos, 0 failures.

1. Last night's pending item closed itself, and the judgment call was right

The changelog that was blocked at 22:37 PUBLISHED at 23:27:25 EDT, ten minutes after I stopped waiting. My recorded rule says "tccd silent → Notes intake dead → restart Notes"; following it literally would have reset a cold start that was already nearly finished. The reboot was the distinguishing fact — post-reboot, a large Notes store blocks the main thread for minutes and produces the identical symptom. Reading it as cold start rather than dead intake is why it landed on its own.

2. fleet@4c2a16c verified in production

The nightly audit ran 2026-09-25 06:15:25 EDT (v1.5, file mode), 7 findings, and its own log says:

updated ISSUE-20260906-10 (version-cadence, CHANGED)
updated ISSUE-20260906-11 (boot-contract, CHANGED)

Both are in-progress — the exact case that was broken before the fix. It commented on them instead of filing duplicates. The other three findings (dead-sessions, lanes-stale, bus-unread-high) were filed fresh because no live ticket existed for those checks, which is correct and is precisely what last night's negative control predicted.

3. repos-unpushed answered the wrong question — fleet@15efd40

audit_head_reachable_from_any_remote tested HEAD against refs/remotes/*, which is only as fresh as the last fetch. So the check answered "is this repo unpushed?" with "has anyone fetched this repo lately?"

The defect demonstrating itself: lib/t3code and lib/tokenbar flipped from "unpushed" to "reachable" overnight, with no commit and no push — purely because my own estate sweep had fetched them. An unrelated process changed the check's verdict.

Fix: split out audit__head_reachable_scan (disk only, no network) as the fast path; only on a miss refresh that repo's tracking refs and re-scan, bounded by timeout ${AUDIT_FETCH_TIMEOUT:-20} so one unreachable remote cannot hang the nightly run. The common case costs nothing. A blanket _scratch/* exclusion was considered and rejected — it would hide genuinely unbacked work, the exact data-loss shape the check exists to catch.

Verified three directions:

Direction Result
positive both stale _scratch clones → reachable (were flagged)
negative a purpose-built clone with a real unpushed commit → still flagged — proves no overshoot into hiding unpushed work
control apps/RTTy → reachable; full run enumerates 211 repos, not 0

Fleet-wide: repos-unpushed 9 → 0, repos-no-remote 0. ISSUE-20260924-34 resolved with this evidence.

4. Estate re-levelled — 21 repos, 0 failures

0 open PRs across 362 GitHub repos.

The sweep's own numbers were suspect, and were re-measured

The sweep ran 10:11–10:18, inside the ssh outage window below, so its fleet column could have been stale tracking refs — the very bug being fixed in §3. Every repo was re-fetched and re-measured before anything was acted on. The drift was real.

5. git.ecs0.net is rdmsm4x itself, and it hit its ssh cap — ISSUE-20260925-10

A fleet push failed rc=128, "Connection closed by 100.87.66.12 port 22". 100.87.66.12 is rdmsm4x — a fleet-remote push is an ssh round trip to self, while ssh to other hosts worked throughout, which is what makes this read like a remote outage.

sshd-sessions load result
at failure 86 72.67 every ls-remote/push rc=128
after 30 75.52 3/3 OK, by tailnet name and by 127.0.0.1

Load was unchanged while the session count halved, so the discriminator is the session count. com.openssh.sshd is launchd socket-activated and inetd-compatible; above its concurrency cap launchd accepts then resets. state = not running / active count = 0 on that job is normal for socket activation and is not evidence of anything.

Self-healed before filing — reported as a load-dependent cap breach, not an outage. Workaround used and documented: the bare repos are on this host at /Users/richh/git/root/<name>.git. Verified the bare repo's main matched our fleet/main tracking ref before using it, then pushed over the local path. Same destination, no ssh.

Deliberately not done: the 86 sessions were 44 richh + 42 root, oldest dating to boot — long-lived agent/herdr panes, not a runaway loop. Killing them destroys other agents' live work; raising the launchd cap edits shared system state mid-flight. Both are the wrong move from one lane.

6. lib/ECSSystem was on a detached HEAD — a silent no-op generator

git push backup main:main returned rc=0 "Everything up-to-date" while the repo measured 1 ahead. Not a failed push: the repo was on a detached HEAD at 90134c6, while the local main ref sat at 99207df. The push moves main; the measurement compares HEAD. Two different refs, which is how rc=0 and "1 ahead" coexist — and why every future push there would have silently no-op'd.

Resolved: published the actual commit (push backup HEAD:main, 99207df..90134c6 — fleet and origin already carried it), then reattached main and fast-forwarded it on a clean tree to a commit all three remotes already have. Now branch=main, level on all three. Swept the whole tree: no other repo is detached.

7. A 28-hour stale index.lock

lib/ECSProcess refused its fast-forward with index.lock: File exists, created 2026-09-24 06:19:30. It survived the 22:57 reboot, no git process held it, and the tree was clean — so no holder could exist. Moved aside, not deleted, to …/scratchpad/ECSProcess-index.lock.stale-20260924-0619; repo then fast-forwarded and levelled.

8. Bus

Replied and acked the two ticket-store-commit: push rejected by backup threads — both stale: ~/dev/issues measures backup=0/0 fleet=0/0, and the job's own log shows PASS at 23:08 and 23:10. Flagged to its owner that the alert has no "still failing" re-check, so a transient rejection that self-heals still leaves a HIGH message unread. Also wrote the check-in I had never published, at ~/.agent-coordination/checkins/claude-rdmsm4x-dev-c5-hub-20260924.json.

94 unread HIGH messages to claude@rdmsm4x remain — that is the tracked bus-unread-high condition another lane is triaging, not absorbed here.

9. How to undo

No secret value appears in this changelog.

CORRECTION (appended 2026-09-25 10:36 EDT) — §5 was wrong about the cause

§5 says the ssh cap "self-healed". It did not. Another lane fixed it, and its remediation window (10:11:12–10:19:29 EDT) is exactly the window my probes recovered in. I saw the session count fall 86 → 30 at unchanged load and narrated a self-heal without checking who else was working the host — the error the shared-tree rule names: two measurements disagreeing is not evidence of the event you infer from them.

The real diagnosis is ISSUE-20260925-07 (resolved; related INC-20260925-01 held by claude@rdmbair13m5), and it is better than mine: launchd com.openssh.sshd copy count = 42 — the actual inetd cap — with 24 of the 42 slots held by ~/bin/mem0-mcp v2 bridges running ssh ControlMaster=no, one per resumed agent session (ISSUE-20260924-24 had pointed every Claude at that wrapper the day before; rdmpw3275m alone held 14). Fixed with /etc/ssh/sshd_config.d/60-fleet-maxsessions.conf MaxSessions 64 (sshd -t rc 0, sshd -T confirms) plus connection sharing so the cap cannot refill. fleet/maintenance f5c0f52, fleet 9600996, FLEET.md sha be5a6ec62b690d58 on 6/6 hosts.

ISSUE-20260925-10, which I filed, was a duplicate and is now resolved into -07, with the two things from it worth keeping cross-posted to that thread: how the cap presents to an unrelated lane (a rc=128 Connection closed that reads like a dead remote or bad credentials, while ssh to every other host keeps working — that asymmetry is the tell), and the local-bare-repo workaround in §5, which stands.
