Re mos-0916 and mos-0917. W9 is done, and I have to correct my interim: the coder did answer. It replied 5 seconds after the chief's message, and the chief relayed the answer to the tester at 01:45:59Z. My 15-minute wait polled the wrong read, so the stop at 02:01:41Z hit an idle coder.

The skills reply, from coder run r293f33bcbc63 (message 7815907c-1332-4526-9ff4-aade5467d300, class RESULT, in reply to 5b58f447, sent 01:45:54.714Z):
"My prompt has these skills: / - ms-unslop / - ms-sdlc / - ms-file-read / - ms-file-write"
Those are the four in its bundle manifest (W9m). Each SKILL.md sha256 there equals git show 89af38a83:skills/<s>/SKILL.md.

The messages from this turn, all seven new rows (messages 543 to 550):
1. 6bbe91b3 tester to chief (W9e) and 49c7dc51 chief's reply ("I took no action and sent no staffing request").
2. 9f38e84c tester to chief at 01:45:33Z, the skill-check request (W9l).
3. 5b58f447 chief to coder at 01:45:48.780Z: "Diagnostic only... It authorizes no work. List the skills in your prompt, then stop. No repo write, commit, push, PR, issue or outward message. Reply with the skills list only."
4. The chief's turn-2 answer to 9f38e84c, which my talk --wait printed at 01:45:54Z ("It hasn't answered yet").
5. 7815907c coder to chief at 01:45:54.714Z, the list above.
6. 97139ccd chief to tester at 01:45:59.450Z, class RESULT, in_reply_to 9f38e84c: the run id, 7815907c and the list word for word.

The chief's tool calls this turn were list_agents, launch {"instance":"coder"}, and send_message twice. The coder made no tool call: one turn, stop end_turn. Nothing went to a repo, push, PR, issue or outside the bus. The coder workspace has HEAD b0d6108 from 10-12 and one untracked stack/ from 10-15, and no file newer than the launch. One note there: my own git status in that workspace changed the .git directory's mtime to 02:07:22Z through the index lock, but the index file itself didn't change.

Why my wait missed it: I polled inbox --tester --json. cli.mjs:298-300 prints only the decisions with --json. Without --json, inbox adds the broker's messages verb, which lists to_role 'human' only (broker.mjs:2190-2206). A message to the tester comes only through message.receive (talk, follow). 97139ccd is still unreceived for the tester. I didn't run follow, because a receive writes a delivery row. Say if you want it received. While checking, W9q ran inbox --tester without --json, and it printed two older pm replies to the human into W9.txt. W9r listed only the metadata of the human's 89 messages, with none since 01:44Z.

How the coder ended: idle from 01:45:54Z. I ran mosaic stop r293f33bcbc63 at 02:01:41.636Z, which printed "stopped mosaic-stack/coder run r293f33bcbc63" and exited 0 at 02:01:41.840Z. runner.log says "claimed by run r293f33bcbc63", then "exiting 0". The launches list afterwards shows only chief rc78c9700c8e9 live (W9p).

S2 at 02:05:17.993Z, with snapshot.mjs checked at 639fd28a first. Schema went from 3h to 3i. Against S1:
- decision_events 20, decisions 20, instance_names 0, message_threads 0, projects 0, thread_claims 0, thread_opens 0, threads 0: unchanged, sha256 the same where it is printed.
- deliveries 1654 to 1673, events 1383 to 1396, messages 543 to 550 (counts only), role_claims 87 to 91, task_comment_cursors 145 to 146, task_snapshots 349 to 351, usage_records 4 to 12. meta changed only schema_digest and schema_version.
- usage byRun: r8fba7e598156 0/0, unknownTurns 1, and r4a96e2142e4d 2/52 are as in S1. The new runs are chief rc78c9700c8e9 input 14, output 1519, unknownTurns 0, and coder r293f33bcbc63 input 2, output 44, unknownTurns 0. The coder's figures match its transcript's usage line.

I also ran an extra read-only check, S2b: snapshot.mjs --held --backup on the W5 backup bus.sqlite (immutable open). Every table has priorSame true, so every row present at the backup is unchanged, and onlyInBackup is []. The backup's sha256sum -c is still OK, and its bus.sqlite hash (eadd96d0) was the same before and after. Its stopTables lists the six tables that have rows added since W5. That's expected after W7 and W9, and it's a pre-restore test, not a W9 stop.

Both plan deviations are in W9.txt for Sage's W11 report. W9.txt is sha256 46a223141339296f, and S2.json and S2b.json are in window/snap/. W10 waits for your go.
