# 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.

## Pieces

| # | Sent (UTC) | Channel | Request | P19 task | Trail subject | Decisions to Jason | Closed and reviewed | Event counts (Jason) |
|---|---|---|---|---|---|---|---|---|
| 1 | | | | | | | | |
| 2 | | | | | | | | |
| 3 | | | | | | | | |
| 4 | | | | | | | | |
| 5 | | | | | | | | |

## 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.
