# Row 162 live reads for the scratch-root plan (sage-0837, sage-0859)

One live read, at 2026-10-18T19:32:16Z, by Darkwing:

```
systemctl --user show mosaic-bus@mosaic-stack.service -p WorkingDirectory
```

Its output, as recorded in the session transcript:

```
WorkingDirectory=/home/jwoltje/.local/share/mosaic-stack/copies/52f35e7a0933e9fa845f59860a5de1709f9e5756
```

`systemctl show` reads the
unit's properties from the user manager. It writes nothing: no unit
file, no drop-in, no state under `~/.mosaic-dev` and no change to the
unit's state.

sage-0859 also allowed a read-only `systemctl --user is-active` on the
bus unit name. It was never called. The scratch data root has no store
file, so `plan_store` sets the store schema from the pointer before it
reaches the `is-active` branch.

The pointer's schema, `3f`, came from git in the canonical checkout, not
from anything live:

```
git show 52f35e7a0933e9fa845f59860a5de1709f9e5756:packages/bus/src/store.mjs
```

Nothing under `~/.mosaic-dev`, the live copies directory or the systemd
units was written. The scratch copy and its removal are in
`scratch-plan-steps.log`; the plan output is `scratch-plan.txt`.

## Rerun for target 8e7ea89a1 (sage-0871, mos-0810 D1-D2)

One more live read, at 2026-10-18T19:51:55Z, by Darkwing, at the start of
the sage-0871 slot:

```
systemctl --user show mosaic-bus@mosaic-stack.service -p WorkingDirectory
```

Its output:

```
WorkingDirectory=/home/jwoltje/.local/share/mosaic-stack/copies/52f35e7a0933e9fa845f59860a5de1709f9e5756
```

The live copy had not changed since the 19:32:16Z read. No `is-active`
read was made this time either. The pointer is hand-written as before:
copy `52f35e7a0`, schema `3f` from `git show` of that copy's store.mjs.

The script was `r1/plan-8e7.sh`, a copy of plan.sh with three changes:
the target is `8e7ea89a1` instead of `origin/refactor`, the scratch root
is `~/darkwing-scratch/r162/plan-8e7` and the output file is
`scratch-plan-8e7ea89a1.txt`. It ran from the r1 candidate worktree on
cfde62f9f, which matched `r1/candidate-manifest.sha256` at 19:51Z. The
scratch copy was made at 19:51:56Z and removed at 19:51:58Z, leaving 0
entries.

One defect in the step log: its "plan: written to" line names
`out/scratch-plan.txt`. My edit changed only the quoted output path, not
the unquoted one in that log line. The output went to
`out/scratch-plan-8e7ea89a1.txt`. The 606fafd43 output kept its sha256
(0586168e…), so the run did not touch it. The step log is kept as
written.
