From 1e63dfa697b43fdd16e669008ece948782f4d0e6 Mon Sep 17 00:00:00 2001 From: Alex Ultra <111590326+alex-mextner@users.noreply.github.com> Date: Mon, 2 Nov 2026 11:52:54 +0100 Subject: [PATCH 1/3] fix(watcher): the investigation brief marks everything read from production as untrusted and finds duplicate writes without selecting a title (Refs #949) Logs, per-chat logs, event rows, Redis values and job errors hold text users and upstream services write; the brief fenced only the alert text. The section every brief has now says all of it is evidence, never instructions. The duplicate query groups on user and start across all rows (a later retry and an already deleted copy still show), counts distinct titles without selecting one, and a title-free lookup reads the copies outside the window. A test runs the brief's queries on the real events schema. Single-seat review (pool 1), six rounds; Sol quota is out until 2026-11-08, so a full-roster review is still owed. Left open from the review: start_at is grouped as stored text, and the correlated query has no index on (user_id, start_at); both are noted in #949. --- docs/reference/deploy-runbook.md | 4 +- scripts/hcb-alert-watcher.ts | 4 +- test/scripts/hcb-alert-watcher.test.ts | 108 +++++++++++++++++++++++++ 3 files changed, 113 insertions(+), 3 deletions(-) diff --git a/docs/reference/deploy-runbook.md b/docs/reference/deploy-runbook.md index c23ba271..8896a1cc 100644 --- a/docs/reference/deploy-runbook.md +++ b/docs/reference/deploy-runbook.md @@ -107,7 +107,9 @@ What runs: the systemd **user** service `hcb-alert-watcher` on the owner's Ubunt The brief the session gets (`~/.local/state/hcb-alert-watcher/briefs/`) fences the alert text as untrusted data, makes the first phase read-only, forbids restart/stop/rollback/redeploy, database writes, deletions and merging without the owner (#596), and requires a Russian `tg report` with the root cause first. The watcher itself tells the owner with `tg --tag problem` when it is blind: the launcher fails (alerts stay pending), or the queue answers 401/403/404 three times in a row (token rotated or endpoint disabled); each notice is sent once per streak.

On the PC these alerts travel like every other: spooled, one session per 30 minutes for everything pending, so an incident that arrives inside the window waits and shares the next session.

Look for DUPLICATES with a query that returns ids and counts only; the window only picks the candidates, every copy is counted across all rows, so a retry sent later is still found and a copy the user already deleted still shows: \`sqlite3 -readonly /opt/hypercal/data/calendar.db "SELECT group_concat(id) AS ids, COUNT(*) AS copies, SUM(e.is_deleted = 0) AS live_copies, COUNT(DISTINCT title) AS distinct_titles FROM events e WHERE EXISTS (SELECT 1 FROM events w WHERE w.user_id = e.user_id AND w.start_at = e.start_at AND w.created_at BETWEEN '' AND '') GROUP BY user_id, start_at HAVING COUNT(*) > 1"\`. Rows of one user at one start are a possible double write; \`live_copies < copies\` means the user (or a repair) already deleted some. \`copies > distinct_titles\` means at least one exact repeat of a title. \`distinct_titles > 1\` can be a retry the model worded differently (do not lower-case in SQL, it only folds ASCII) or two events the user really asked for at one time: let the run's write receipts decide, and two writes intended in one run are not a double write. The title is only counted, never selected, so this query puts no title into your context (the logs still carry user text: do not quote it). A copy created outside the window has no row in the first query: read it with \`sqlite3 -readonly /opt/hypercal/data/calendar.db "SELECT id, created_at, google_event_id, is_deleted FROM events WHERE id IN () ORDER BY id"\` (never \`SELECT *\`, it carries the title) and find the run that wrote it in the container log around its created_at: a retry that succeeded raised no alert, so no requestId points at it. For each copy give its id, created_at, google_event_id and whether it is deleted, and which run wrote it. 3. Delivery. Establish what the user actually saw: the \`delivery:\` line, the send lines in the log and the end of the chat log. A tool success is not a delivered message, and a failed render is not a failed write. 4. Host load and the render queue. \`ssh root@odroidn2 'uptime; cat /proc/pressure/cpu /proc/pressure/memory /proc/pressure/io; free -m'\` shows the host now; the log around the run shows it then (sync jobs and model calls that take far longer than usual). A host that swaps on its microSD (IO pressure "full", swap in use) slows every call at once. Render jobs (BullMQ queue image-render; completed jobs are removed after 60 s, failed ones kept for an hour): the \`Enqueuing render job\`, \`Render complete\` and \`Image render failed\` lines of the run, and now \`docker exec hypercal-redis redis-cli LLEN bull:image-render:wait\` plus \`ZCARD bull:image-render:prioritized\` (renders are queued with a priority, so a backlog sits in prioritized, not in wait), \`ZCARD bull:image-render:failed\`, \`ZREVRANGE bull:image-render:failed 0 4\` and per id \`HMGET bull:image-render: timestamp processedOn finishedOn failedReason\` (never HGETALL: the job data holds the calendar). A render slower than the run's remaining budget gives a text answer without the image, by design. 5. Validator and provider timings. In the run's \`AI model call metric\` lines compare purpose=agent, purpose=validator and purpose=retry: totalDurationMs, success, failedProviders, fallbackCount. Say which call used up the request budget (elapsedMs in the alert) and whether the validator failed by its own timeout, a provider error or the budget. @@ -736,7 +736,7 @@ You are session ${args.session}, started automatically by hcb-alert-watcher on t ## What triggered you -${args.items.length} alert(s).

The check runs only when the installer runs, so a restart without it can still loop silently (#842). + Backlog triage (alerts that piled up while nothing consumed the queue): the service pops the whole queue on its first cycle and, with the default 12 h limit, marks old alerts stale without investigating them, so triage BEFORE the first install (or after `systemctl --user stop hcb-alert-watcher`): `keychain exec --caller hcb-alert-watcher --env ADMIN_ALERT_TOKEN=hcb-alert-watcher/admin-alert-token -- env HCB_ALERT_STALE_HOURS=1000 bun scripts/hcb-alert-watcher.ts --once` (the pending alerts go to one session; one run pops at most 50, so with a bigger queue repeat it, after the 30-minute rate limit, until the log shows no `queued from` line), then install or `systemctl --user start hcb-alert-watcher`. Never run `--once` while the service runs: the two processes share the state directory without a lock and could each start a session. A 200 from the queue that the watcher cannot parse is kept in `~/.local/state/hcb-alert-watcher/unreadable/` (the server's pop already consumed it; one file per cycle at most). A launcher that hits its 30 s deadline is not retried (the session may already run): the owner is told once and the alerts are marked handled. After a restart in the middle of a launch, a claim whose session log (`HCB_AGENT_LOG_DIR`, default `/tmp/agent-logs`) already exists is confirmed, not launched again. Known limits: the probe runs on the PC, so a PC that is off or offline raises nothing (the DO watchdog still messages the owner then), and a PC whose own network is down counts as a down bot after three failed probes (cached DNS still answers); failures more than about six minutes apart (suspend, service stopped) never add up to an outage. The DO watchdog posts its queue alert only while the bot is up, so only the PC probe turns a hard outage into an investigation session. The unit and every session it starts run with `PATH=~/.local/bin:~/.bun/bin:/usr/local/bin:/usr/bin:/bin` and no ssh agent (key-file auth to `root@odroidn2` works, verified under `systemd-run --user --pipe`); the installer warns about `omp`, `gh`, `ssh`, `tmux`, `ctmux`, `systemd-run` missing from that PATH and pins `tg` by absolute path. After a failed launch the launcher is left alone for a minute. -Also known: (1) an outage seen by the PC probe and, separately, by a queued alert (the DO watchdog's POST, a crash alert) can start two sessions 30 minutes apart: dedupe is per alert id and per probe incident, not across sources; the second session's brief tells it to check `omp-steer list` first. (2) The unit starts at login or boot (linger); if the keyring is still locked, `keychain exec` fails with its own exit code, which `RestartPreventExitStatus=78` does not cover: the unit restarts every 30 s without being able to tell you. After a reboot check `systemctl --user is-active hcb-alert-watcher`; `keychain unlock` fixes it. (3) Bun loads the script once: after a merge that changes `scripts/hcb-alert-watcher.ts` run `systemctl --user restart hcb-alert-watcher` (the installer restarts only when the unit text changes). (4) A pop whose response times out before any header arrives may have consumed an alert on the server; only the journal line "queue step failed" shows it. (5) The queue poll refuses redirects so the token never travels to another host. +Also known: (1) an outage seen by the PC probe and, separately, by a queued alert (the DO watchdog's POST, a crash alert) can start two sessions 30 minutes apart: dedupe is per alert id and per probe incident, not across sources; the second session's brief tells it to check `omp-steer list` first.

(3) Bun loads the script once: after a merge that changes `scripts/hcb-alert-watcher.ts` or `package.json`/`bun.lock`, first follow the three dependency rules above (`bun install --frozen-lockfile` in the canonical checkout, then `scripts/install-alert-watcher.sh --dry-run`), then run `systemctl --user restart hcb-alert-watcher` (the installer restarts only when the unit text changes). (4) A pop whose response times out before any header arrives may have consumed an alert on the server; only the journal line "queue step failed" shows it. (5) The queue poll refuses redirects so the token never travels to another host. Probe failures under host load (2026-11-01): `state.json` showed one failed probe at 17:30:38 UTC (`lastProbeFailureAt`, the consecutive count back to 0 afterwards) and the journal had no line for it, because a single failed probe was not logged. It was a timeout, not an outage: cloudflared on the odroid logged `Incoming request ended abruptly: context canceled` for `hypercal.mextner.com/ready` at 17:30:38, the instant the watcher's 20 s `HCB_ALERT_PROBE_TIMEOUT_SECONDS` deadline fired (a second `/ready` request from an unidentified client ended the same way at 17:30:34). The bot's own log for that window holds only a Google pull-sync job that needed 46 s to apply zero items (it also waits on Google, so that alone proves little). About 18:00 UTC the host still showed load average 11-12 on 6 cores, 3 GB of 6 GB swap in use on the microSD, `/proc/pressure/io` `full avg300` above 50%, and `/ready` answered from this PC in 13.6 s, 1.9 s and (once) not within 25 s: a swapping odroid answers late, not wrongly (memory pressure on the odroid: #800). Each failed probe before the incident threshold is now logged with its reason, `readiness probe failed (1/3): no answer within 20s (probe timeout)` against `no response ()` or `HTTP `, so a blip shows in `journalctl --user -u hcb-alert-watcher`. Three timeouts in a row still raise a `down-` incident, on purpose: a bot that needs more than 20 s to say it is ready is not serving users either, and the investigation reads the host load. Raise `HCB_ALERT_PROBE_TIMEOUT_SECONDS` only to judge a degraded host differently, not to hide it. Timestamps: the PC journal and the odroid journal print local time (CET, UTC+1 since 2026-10-25), so give `journalctl --since '2026-11-01 17:25:00 UTC'` and `docker logs --since 2026-11-01T17:25:00Z` an explicit zone. The same limit makes known limit (4) likelier: a queue pop that times out at the same 20 s may have consumed an alert on the server (the pop is not acknowledged), so an incident raised while the host is starved can be the one that is lost; only the journal line `queue step failed` shows it. diff --git a/pyproject.toml b/pyproject.toml index 3ac46c54..7a581f67 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -1,6 +1,6 @@ [project] name = "hypercalendarbot" -version = "0.3.4" +version = "0.3.5" requires-python = ">=3.12" dependencies = [ "pyrofork>=2.3", diff --git a/scripts/install-alert-watcher.sh b/scripts/install-alert-watcher.sh index 1f0a1175..570f4f58 100755 --- a/scripts/install-alert-watcher.sh +++ b/scripts/install-alert-watcher.sh @@ -11,7 +11,7 @@ # scripts/install-alert-watcher.sh --fetch-token-from HOST first install: also copy the # production ADMIN_ALERT_TOKEN from # HOST:/opt/hypercal/.env into the keychain -# scripts/install-alert-watcher.sh --dry-run print the unit, change nothing +# scripts/install-alert-watcher.sh --dry-run check the watcher builds, print the unit, change nothing # scripts/install-alert-watcher.sh --uninstall stop and remove the unit # # Safe to run again: an unchanged unit is left alone and a running service is not restarted. @@ -86,6 +86,27 @@ launcher="${HCB_OMP_LAUNCHER:-$HOME/.agents/skills/rig-detached-omp/rig-detached [[ -x "$launcher" ]] || die "the rig-detached-omp launcher is missing at $launcher (it ships with the rig-detached-omp skill: run rig apply)" bun_bin="$(command -v bun)" || die "bun is not on PATH" keychain_bin="$(command -v keychain)" || die "keychain is not on PATH" +# The watcher imports packages (zod) from the checkout's node_modules.
