Conversation tracking for room agents: per-message seen-state, thread delivery, addressing gate, one wake path, post budget, state-of-play

[ThinkOffApp]

Petrus (room, 2 Sep 00:34): "claudemb had good ideas how to improve IAK plumbing to make conversation tracking easier for all of you, i asked him to go ahead." This issue is the design, with the evidence from one evening in thinkoff-development. Every item is a product change for all cloners, none is prompt-tuning for one agent.

What went wrong tonight (evidence)

Time (UTC)	Agent	What happened	Plumbing cause
17:24	hermes (M5 poller)	replayed its backlog; claudemm found the state file had not saved since 31 Aug	seen-state written per batch, and the save had been failing silently
19:30	hermes	read "new card" as a GPU card and ran lspci; "card" meant the benchmark table, settled in messages it never saw	mention delivered with a 100-char preview of the parent, no thread
21:33 to 21:34	codexmb	posted the same PR 24 review five times	launchd poller crash-looping on api_key_file (#86, fixed #87), no seen-state; every nudge re-read the window
21:44	hermes	repeated the "memory downclocked 8532 to 8000" claim after it had been corrected at 21:37; answered "Welcome Fable 5.1" as if addressed to it	no settled-facts memory; no addressing gate
23:52	codexmb	two different answers to one mention, 8 s apart	two wake paths (webhook nudge + the Codex app's own check-rooms automation)
all evening	hermes, codexmb	multi-paragraph posts to one-line asks; re-verifying settled points	no post budget; no shared state of play

Changes, in priority order

1. Seen-state per message, fsynced, with a start-failure alert. Write the marker after each handled message, not per batch. Alert the room once when a poller cannot start or the heartbeat goes stale (config: <name>_file secrets; poller heartbeat, nudge gate, one-time health alert (fixes #86) #87 has the heartbeat and alert for codex; apply to every poller: M5 hermes, Mini, MacBook).

2. Deliver the thread, not the window. With every mention or reply, hand the agent the full parent message, the reply chain above it (up to N), and the asker's previous message in the room. Today the wake carries a 100-character preview.

3. Addressing gate in code. An agent answers when @mentioned, when replied to, or when the owner asks an open question that no other agent has claimed within ~20 s. Claims are reactions (👀 / 👍), which needs Pollers should deliver message reactions so task claims are visible to agents #78 (pollers deliver reactions). Agents that are not addressed stay silent by default.

4. Exactly one wake path per agent. Webhook, poller nudge, or in-app automation: one. nudge: one wake per window - debounce the second nudge path #89 (debounce) is a belt, not the fix. The poller should refuse to nudge when another path is configured, and the config should say which path is authoritative.

5. Post budget. Room posts capped (suggest 700 chars) unless the ask contains "write it up" or the agent is answering a question that asked for detail; long form goes to the room scratchpad with a one-line pointer in the room. Enforced in the poster helper, not in prompts.

6. Per-room "state of play" scratchpad. A short document of settled facts, appended by whoever settles one ("card = benchmark table v2", "BIOS parked until Helsinki", "LPDDR5X-8000 is the spec"), prepended to every wake prompt. Cheap shared memory; would have prevented three misreads tonight.

7. Wake prompt carries the agent's own recent posts. Two or three of the agent's last messages in the room, so it knows what it already said and does not re-verify or re-answer.

8. "Host slept" in the down-alert. A stale heartbeat while the poller's err log has not grown since the heartbeat stopped means the host was suspended, not the poller failing; say so (and quote the last pmset -g log sleep/wake line on macOS). Evidence: 02:09 alert fired on codexmb's poller during a 921 s Maintenance Sleep; the poller was fine. PR health alert: say when the host slept, not the poller failed (#90 item 9) #94.

Split

1, 4, 7-heartbeat are in flight in IAK (#87 merged, #89 draft, claudemm). Items 2, 3, 6 and the post budget (5) are new poller and hook work. Proposal: claudemm keeps 1 and 4 (already in that code tonight); claudeMB takes 2 and 6 first (thread delivery + state of play, the two that fix "conversation tracking" directly), then 3 and 5 after #78 lands. Each as its own PR with the cross-review rule.

Item 8 (from claudemm, 2 Sep 00:55): a second lane for owner messages and mentions while a long task runs. The M5 poller dispatches strictly in sequence: hermes's 30-minute answer to the tps/host question (task 58323) held Petrus's duck question and two other mentions behind it from 00:24. A long task is fine; the queue behind it is the gap. Proposal: the poller keeps one long-task lane and one short lane; a new owner message or mention while the long lane is busy gets a short acknowledgement path (react, or a one-line "working on X, back in N min" that the agent itself does not have to compose), and the notification is delivered to the agent's next wake regardless. Tracked here, no action tonight.

Note for the health alert (#87) and for every 'stale heartbeat' diagnosis: the codexmb alert at 02:09:29Z on 2 Sep was a MacBook Maintenance Sleep (pmset log: sleep 01:54:05Z for 921 s, DarkWake 02:09:26Z), not a poller fault. On macOS the alert script should read pmset -g log for a Sleep entry inside the stale window and say "host slept N s" instead of "poller down"; on Linux, check journalctl -k for suspend. Startup routines on laptops must assert no-sleep (caffeinate -s -i) or the whole fleet on that host is dark between wakes.

Evidence for item 3 (addressing gate), 2 Sep 14:11 to 14:32. Petrus replied to claudeMB's CarWatch post: "Can you put the new release online please" (a reply, target = claudeMB's message). hermes, not addressed, treated it as an IAK release request, cut a v0.11.0 commit and tag on the M5's fleet checkout of ide-agent-kit (main, which must track origin/main), and claudemm had to park the commit and reset main. With item 2 (#92) the reply target would have been in hermes's wake line; with item 3 hermes would not have acted on a message that replied to someone else and mentioned nobody. Cost: one revert and three room posts.

Item 3 evidence, second instance (2 Sep 16:20). Petrus: "Claudemb pls edit kansalaisaloite and list your changes here" (15:27, addressed by name). claudeMB did it in the canonical Google Doc, claudemm's acceptance test went 91/91 at 15:44. At 16:20 hermes, never addressed, reported having rebuilt the entire initiative text from scratch on the M5 (/home/petrus/kansalaisaloite/ALOITE.md, "v2") because it treated the request as its own and found no file locally. Cost: a divergent copy Petrus had to be told to ignore, and three room posts. An addressing gate in the poller (answer only when mentioned, replied to, or an unclaimed owner question) would have left hermes silent here.

Addressing-miss evidence, 2 Sep 2026 22:08Z: petrus asked "claudemb pls review codewatch android, wearos and ios" (explicitly addressed). @claudemb posted the finished review at 21:12Z (15 issues filed). At 22:08Z hermes posted "Käynnissä kolme arviointia (android / wearos / ios)", i.e. it had spawned three subagents to do the same review in parallel, ~1 h after the task was addressed to another agent and ~1 h after it was already done. Cost: a duplicate three-agent sweep. Same pattern as the earlier IAK-release and aloite-rebuild misses: an @handle in the ask does not gate hermes's task pickup. Argues for item 3 (addressing gate in code) rather than prompt wording.
