Applies the document contract from
docs/plans/2026-08-20_stack-docs-flatten-and-alignment.md section 3, partially:
`kind` and `status` only. `parent` is deliberately held until the flatten in
section 4 lands, so that 127 documents do not have to be re-pointed by hand
when docs/fleet/NORTH_STAR.yaml moves to docs/NORTH_STAR.yaml.
Scope, measured on origin/next at 63069149:
127 live docs = all *.md under docs/ minus docs/archive/ minus docs/_old_structure/
104 stamped here
19 held operator judgement (plan section 9), worklist in the same PR
3 held the SUPERSEDED TASKS.md stamps, which cite the moving path
1 untouched docs/fleet/FLEET-DOCTRINE.md, already stamped in W1
Kinds applied: 54 guide, 34 record, 9 spec, 6 tracking, 1 projection.
Every row carries a confidence and a one-line rationale in the worklist.
Two collisions with the existing state, both flagged rather than resolved:
1. docs/README.md:150-160 already documents a front-matter convention
(title/type/audience/status/source_of_truth) with its own allowed values.
It is applied to 4 of 127 files. Its `status` vocabulary is
current|draft|deprecated|historical; the new contract's is active|superseded-by.
The key collides. This commit lets the new contract win and rewrites
`status: current` to `status: active` on those 4 files, keeping their other
legacy keys untouched. No code reads any of them: `git grep source_of_truth`
outside docs/ returns nothing. docs/README.md still prescribes the old
convention and is an operator row, so it is not edited here.
2. Two of the plan's 20 operator rows are YAML files, not markdown
(docs/fleet/examples/roster-v2.yaml, docs/openapi-tess.yaml), and the
contract's front-matter form has no defined meaning for a .yaml document.
That gap also applies to docs/fleet/NORTH_STAR.yaml, the source of truth
itself. Raised in the worklist.
A third row from the plan, docs/fleet/north-star.md, no longer exists: W1
renamed it to docs/fleet/FLEET-DOCTRINE.md.
Verification: 104/104 parse with the expected kind and status in front matter;
the check was shown to reject a wrong kind before it was trusted. The diff
removes 4 lines total, all of them `status: current`.

# Systemd and tmux Troubleshooting
|
|
|
|
Start with read-only mosaic fleet status, `doctor`, and `verify`. Do not manually adopt, rename, terminate, or recreate sessions while ownership is ambiguous.
|
|
|
|
## Decision table
|
|
|
|
| Finding | Meaning | Safe next step |
|
|
| ------------------------------- | ---------------------------------------------------- | ------------------------------------------------------------------------------------- |
|
|
| Empty roster `tmux.socket_name` | Literal default tmux server | Do not substitute the named `mosaic-fleet` socket. Use roster-derived commands only. |
|
|
| Non-empty socket | Exact named socket | Never target another socket or infer a per-agent socket. |
|
|
| holder: missing | Required exact holder absent | Inspect installation/projection readiness; do not create an unproven holder manually. |
|
|
| `ownership-mismatch` | Holder identity or global environment differs | Stop. Verify private install identity and managed paths before retry. |
|
|
| `missing-session` | Desired-running roster agent lacks exact session | Check service/runtime preconditions; review apply dry-run. |
|
|
| `unexpected-session` | Desired-stopped roster agent still has exact session | Confirm ownership; only reconciler may target the exact proven roster member. |
|
|
| `disabled-running` | Disabled roster member is observed running | Inspect and reconcile only after ownership proof. |
|
|
| `unmanagedSessions` | Unknown session exists on configured named socket | Report and investigate separately. Reconciler will not kill or adopt it. |
|
|
| stale/concurrent generation | Desired state changed since plan | Reload roster/generation and recompute the plan. |
|
|
| stale or ambiguous lock | Prior writer/cleanup cannot be proven | Inspect ownership; do not blindly remove the lock. |
|
|
| projection failure | Derived files incomplete | Keep roster as authority and regenerate projections. |
|
|
| lifecycle failure | Projections complete, runtime convergence incomplete | Inspect the exact owned resource, then rerun with current generation. |
|
|
|
|
Systemd state, tmux state, heartbeat, and generated files are observations/projections, not alternate desired state. Explicit apply/reconcile honors stopped/disabled intent, but current unit enablement and launcher projections do not yet prove lifecycle-safe reboot; inspect unit enablement before reboot and treat stopped/disabled boot preservation as an FCM-M3-002 hold. Current roster-v2 status commands also do not read heartbeat files. Executable gates do not provide site cutover/rollback or package asset-revision repair.
|
|
|
|
Errors and troubleshooting output never print legacy sensitive values, credential contents, or privileged command text. Use stable codes, key names/hashes, exact roster identities, and bounded recovery actions. See [status and drift](../reference/status-and-drift.md) and [reconcile and recover](reconcile-and-recover.md).
