Merge 3ea52fc3e475a3e7c430812bde4209258416e57b into a0a61a8237f61344a01448a97954df603d8fff73. Retain the V2-to-V3 migration dependency alongside native system flock support, removing the replaced fs-ext dependency. Union the lockfile workspace importer entries; frozen installation validates the result without regeneration.
Preserve release publint async lane-signal cancellation, close ownership, and spawn-error regressions, satisfying the incoming CI budget intent. Keep canonical, prompt, preset, and latest migration regression behavior. Rename an arbitrary preset fixture value to custom-agent to avoid the inherited vendor-rescope false positive without changing test semantics.
Validation: frozen install; full build including Darwin addon; focused V3/persistence/prompt/publint and runtime tests; built migration, two-process lease, and loader smokes; native flock and package-matrix tests; touched dependency and CI owner tests; all hygiene leaves (vendor residue repaired and rechecked); doc-sync 34/34.
The minimal compositions serve the same models that trained against a
one-shot `bash` tool; three surface differences remained visible to them.
- Every settled command now appends `[Command finished with exit code N]`,
including exit code 0, instead of `[exit code: N]` only on failure. A
timeout appends `[Command timed out or OOM]` after the partial output.
- Trailing newlines are all dropped before the status trailer rather than
only the last one.
- The `bash` description in the `minimal` preset and the `sdk-minimal`
bundle replaces the two fixed network lines with a single environment-
dependent line; the pwsh description is unchanged.
Tests, READMEs, the web minimal-preset schema snapshot, and the packaged
Python minimal model-visible snapshot follow the new wording. The
standalone `persistent-tools` SDK replay fixture keeps its own copy of the
old description since it is a per-launch customization, not the profile.
The inventory keeps dsh-app-boot an optional, type-only peer, so the walk
over an entry's owning groups moves behind ProfileRuntime.userDisables(): a
consumer with the runtime asks it, one without reports composition as before.
The module graph and the cordis catalog follow.
The runtime's user-disabled row ids now come from the committed composition —
composeProfileStack collects them from the user layers it composed — so a
rejected or half-written patch file no longer makes the list disagree with the
running tree or fail to parse. The inventory attributes a row disabled through
a group the user disabled to the user, through the shared userDisablesEntry
walk, and lists a user-layer row the composition left out under the new user
trust instead of builtin.
