Slice 1 S7 run log (row 42, #1524)

Append-only. Brief: docs/plans/2026-10-04_slice-1.md, "Slice 1 S7: acceptance, five pieces in a row". Gate: Jason, from the five trails.

2026-10-12T18:30Z start (lead decisions 94, 114, 115)

Row 42 moved briefed to in-progress at queue rev 673 (op sage-42-start-q118), on Mos's sage-0092 and Jason's Q118 A.

What counts as a piece: one of the first five Mosaic Stack requests Jason sends to the PM through the Console or mosaic talk pm after the Q119 confirm at 2026-10-12T18:27Z. A request sent to T3 Mos doesn't count. Mos gives Jason the command and logs the slip on Vikunja #205 (decision 114).

What each piece needs to pass (the brief): carried to a closed, reviewed task; its trail in mosaic trail and the Console; only gated decisions reached Jason; the bus event counts, which are the first measures (REQ-EVT-1).

How I track it. Agent seats can't read the trail or the bus (REQ-DEC-3; scripts/mosaic trail from this seat refused before 2026-10-12T18:30Z, "this runs only from a human shell"). So I track each piece through what I can read: the P19 task the PM creates (sync key), and any queue row and Gitea issue the piece makes. For each piece this log records the trail subject (the task ref vikunja:19/<id>, or the message id if Jason gives it), so Jason can read the trail and count the events in the Console #/trail or with mosaic trail <subject> at his gate. Nobody builds an agent read path around that (decision 115).

Known gaps on day one:

• The Console doesn't show the reply to a web send yet. That's row 81 (Dewey, in progress); mosaic talk pm shows replies until it lands.
• Mos files the friction they see on #205 with the dogfood label.

2026-10-12T18:49Z reachability check, not a piece (Mos sage-0095)

Jason ran /mnt/storage/src/mosaic-stack/scripts/mosaic talk pm "Can you hear me now?" (the #225 stopgap path) and got sent 6b5b7aef to pm. So the human proof passes and the broker accepted the message.send. It is a reachability check, not a Mosaic Stack request, so it is not piece 1 (Mos's view, and mine).

Nothing answers it yet. scripts/mosaic launches list (which reads bus-host/sessions.json and is allowed from agent runs) prints "No sessions". mosaic-bus@mosaic-stack has run bus start mosaic-stack without --pm since 2026-10-11T18:19:28Z, and its cgroup holds only the host and broker processes. The unit template has no --pm (packages/cli/systemd, ExecStart), so a plain restart wouldn't launch a PM either. Decision 91's watched --pm restart (Mos's) hasn't happened. Until a PM runs, no S7 piece can be answered. Whether the PM picks up 6b5b7aef when it launches, I haven't checked.

2026-10-12T18:56Z PM running; both reachability checks answered (Mos sage-0096, sage-0097)

Mos added a temporary drop-in, ~/.config/systemd/user/[email protected]/pm.conf, that sets bus start %i --pm, and restarted the unit at 2026-10-12T18:53:34Z. The journal shows "launched pm: run r0566c6d9e459, claude-code claude-opus-5-5", and scripts/mosaic launches list shows the run, by jason. The bus now runs the checkout as of that restart. Row 85 (#1579) removes the drop-in when it lands.

This corrects the last line of the 18:49Z entry. The PM's runner calls message.receive as it starts, and the broker returns every pm message not yet delivered (packages/harness/src/runner.mjs:314, packages/bus/src/broker.mjs:771-777). So a message queued before the launch is answered.

Two reachability checks, neither a piece (Mos's view, and mine):

• 6b5b7aef ("Can you hear me now?"), sent before the PM ran. It was answered by c61d6328, RESULT re 6b5b7aef, from Jason's screenshot via Mos. His talk had timed out by then, so he saw it in a second call.
• a8df1e12, answered by 375bfb6a (same source).

The run directory shows turn 1 at 18:53:35Z and turn 2 at 18:55:12Z, both with empty stderr, and runner.log has no failure line. I read only file names, sizes and the runner: lines, never turn content.

Plain mosaic (the Q81 wrapper) still gets human-required (#225 c60). Until row 85 lands, Jason uses the full path, /mnt/storage/src/mosaic-stack/scripts/mosaic talk pm "...", or the Console. Notifier off: notify.json sets binding null, so it was off before the restart too.

S7 piece 1 is Jason's next real Mosaic Stack request.

2026-10-19T18:33Z when pieces open (Mos mos-0855, on sage-1024)

Q111 (Jason): "time is irrelevant. We move through tasks with a "next..." philosophy." So row 42 has no start date, pace or close date. I proposed 10-21 to 10-26 in sage-1024, and Mos turned the dates down and kept the order. The rules from here:

a. Piece 1 opens once Window B (row 126, 3i) is verified live. If B can't run, for example because row 169 lands first and B gets redrawn, piece 1 opens after whichever window runs next is verified, and I tell Mos. b. Jason sends each piece when he's ready. Agents push no pace and set no deadline. c. No re-pin while a piece is open. The window past c216f47db goes between pieces, with Jason's ok. d. Before piece 1 opens, I check on the live pin which role takes a piece and that a human message to it gets answered: either the role is running, or launch.by is told and the role is in launch.instances (row 152). The 8e7ea89a1 window found pm not running with launch.by = chief. The result goes in this log.

Mos passes this to Jason when piece 1 opens, not before. Lead decisions 94, 114 and 115 stand.

2026-10-20T12:54Z trigger (a) met; check (d), the part an agent can read

Trigger (a): the Part A window put 490e2771d3 live (pm true, schema 3i, proof off), checked by Mos (mos-0928). That is the first window verified since mos-0855, and it carries 3i, so piece 1 may open.

Check (d), what I can read from this seat at 12:54Z:

• scripts/mosaic launches list prints one run, r34520a581318, mosaic-stack/chief, claude-code claude-opus-5-5, by jason, since 2026-10-20T07:58:02Z, running.
• The bus, the Console (7332) and that run's runner all run from copies/490e2771d3d0, and the bus runs bus start mosaic-stack --pm.
• What I can't check: that a human message to the PM gets answered. Every other scripts/mosaic verb refuses an agent run ("this runs only from a human shell"), and the tester switch is Jason's. That half needs a human send, or Mos's Part A STATE evidence if it holds one.

Rule (c) still applies: Part B (P19 385) is a window, so if Jason gives J1 while a piece is open, Part B waits for that piece to close.

2026-10-20T12:55Z mos-0960: the first message to pm is a reachability check

Mos accepted the correction (no date) and agreed trigger (a) is met. Check (d) item 3 is not settled: the Part A window (W9) tested only the tester thread d0ba7a66, and S1 had no human thread, so no talk or follow answer from pm exists on 490e2771d3. Mos read the live business file: launch.by is chief, and pm is in launch.instances with cto, assistant, coder and reviewer, with no threadIdleSeconds. Mos's reading of cli.mjs:345 (not a test) is that a talk to pm tells the chief to launch pm.

Ruling:

• Jason's first message to pm is a reachability check, not a piece, like 6b5b7aef and a8df1e12 on 10-12.
• If pm answers, his next real Mosaic Stack request is piece 1.
• If pm doesn't answer, I file the defect and piece 1 doesn't open.
• Rule (c) stands. Mos recommends to Jason that J1 and Part B go before piece 1 if he gives both together, so the pieces run on the final Console auth.

Mos tells Jason in the morning summary.

2026-10-20T17:48Z correction: on a pinned host Jason uses plain mosaic (Mos mos-0968)

This supersedes the 10-12 line at 18:56Z, "Until row 85 lands, Jason uses the full path, /mnt/storage/src/mosaic-stack/scripts/mosaic talk pm "..."". Row 85 landed, and the host, bus and Console now run from the pinned copy 490e2771d3. The bus takes human commands only from the tree it runs from. The canonical checkout is not that tree.

Jason ran the full-path command Mos gave him from that line. It refused with human-required: "the bus accepts these commands only from the tree it runs from; on a pinned host run mosaic on PATH". ~/.npm-global/bin/mosaic now execs copies/490e2771d3d0/scripts/mosaic, which I read at 17:48Z, so Jason uses plain mosaic talk pm "..." or the Console. Friction is on Vikunja #205, comment 369.

Nothing else changes. The refused command never reached pm, so the reachability check (mos-0960) has not happened and piece 1 is not open.

2026-10-20T17:54Z S7 reachability pass (Mos mos-0969)

Jason ran the plain PATH command from the 17:48Z entry. His output, as Mos relayed it in mos-0969:

[jwoltje@dragon-lin winA]$ mosaic talk pm "Can you hear me?"
sent 51cebff7 to pm
pm isn't running, chief has been told
pm (RESULT, re 51cebff7) cff1e9ad:
Yes, I'm getting your messages. I haven't changed anything on the tracker. What do you need?

pm was not running when 51cebff7 arrived. The chief launched it, and pm answered with cff1e9ad. Under mos-0960 this is the reachability check, not a piece. It passed, so the "pm doesn't answer" branch does not apply and no defect is filed.

Piece 1 is Jason's next real Mosaic Stack request to pm. It is not open yet.

2026-10-21T01:14Z dates (sage-1622, Mos mos-1148, Vikunja #442)

Mos accepted the plan with changes C1 and C2. The dates are latest-by markers (Q111).

1. Pieces 1-5 open by 2026-10-23 23:59Z. Mos gives Jason the plain command after tonight's open items with him (Q13 on PRD 1.8, the 1012 and 1008 boot). I don't ask again.
2. C1: no piece is pinned to a copy. A piece runs on whatever copy is live when Jason sends it. For each piece this log records the activation id at send. A piece still open across a window gets the new activation id recorded too.
3. C2: neither the Q175 phase 2 window (10-23) nor the 10-24 re-pin window rolls back or restores while a piece has history, unless that window has failed. If a restore happens anyway, this log names the pieces to redo.
4. All five closed and reviewed by 2026-10-26 18:00Z. Jason reads the five trails at his gate on 10-26 or 10-27. A pass starts merge plan step 1 under decision 146, and step 4 stays his.
5. Fallback: if fewer than five pieces are open by 10-23, the gate moves to 10-28. No agent opens a piece in Jason's place.

When Jason sends a piece, I tell Mos its message id.

Correction (2026-10-21T01:06Z): the heading above says 01:14Z. The clock read 2026-10-21T01:05:56Z when I wrote that entry, so 01:06Z is the right time.

2026-10-21T01:20Z Jason's pre-S7 checks (mos-1154)

Between 01:11:06Z and 01:13:03Z Jason sent pm five requests with mosaic talk pm: ed9e1e14, 51c19692, 94f5d62c, 0645a3b7, f75449c0 (bus seq 1583 to 1591). pm run rc9e993da24cf answered each in 4 to 16 s. They were two jokes, the sandwich, the purpose of Mosaic Stack and pm's mission. pm made no task and raised no decision for any of them, and said so each time. Mos's reading, which I take: none is a piece, because a piece has to become work that gets closed and reviewed. They are recorded as Jason's pre-S7 checks. The five pieces are still open, latest-by 10-23 23:59Z. Activation at send: copy 4429a104f, as in the 01:06Z entry (C1). Source: Mos (mos-1154) read the bus. I didn't read the message bodies.

pm also told Jason that its state snapshot lists only the first 50 of 198 open tasks and that it pages the rest with list_tasks. That is the row 109 (#1603) design: broker.mjs state returns cap: TASK_PAGE (50) with total, and list_tasks pages up to TASK_PAGE_MAX (200).
