veronica f0d2dd9920 docs(W4): stamp kind and status front matter on 104 live documents
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    3 held        the SUPERSEDED TASKS.md stamps, which cite the moving path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   current|draft|deprecated|historical; the new contract's is active|superseded-by.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`.

# Legacy Fleet Class Aliases
Fleet class compatibility is intentionally narrow. The shared resolver accepts exactly three legacy
class names and converts them to canonical classes before persona lookup:
| Legacy value | Canonical value | Migration action |
| ---------------------- | --------------- | ---------------------------------------------------------------------------------------------------------------------- |
| `implementer` | `code` | Replace class and tool-policy references with `code`. |
| `reviewer` | `review` | Replace class and tool-policy references with `review`. |
| `operator-interaction` | `interaction` | Replace class and roster-v2 tool-policy references with `interaction`. The legacy service artifact remains compatible. |
Alias support preserves existing inputs while provisioning and typed semantic output use canonical
identities. Requested and canonical class values remain separately observable during semantic
validation.
## Lookup and override behavior
Canonicalization precedes baseline and `roles.local` lookup. A legacy-named override such as
`roles.local/implementer.md` is not a separate authority and is not selected for an `implementer`
request. Customize the canonical role instead, for example `roles.local/code.md`.
The compatibility file `operator-interaction.md` remains shipped, but `interaction` is the canonical
role class. Tess is an example display name only.
## Unresolved and custom classes
No names are inferred from historical usage, instance names, or similar wording. `worker`, `analyst`,
`canary`, Tess, and Ultron are not aliases. An otherwise unknown class is accepted only if the shared
resolver can read an actual baseline or `roles.local` contract for that exact class. A `LIBRARY.md`
row without a readable contract fails semantic validation.
Custom classes receive no protected authority implicitly. Protected class/tool-policy mismatches
fail closed.
## Retirement guidance
New configuration should emit canonical values. Existing inputs may use the three aliases during the
compatibility period, but operators should migrate class and tool-policy fields together. Do not
create new legacy-named role overrides; move their intended content to the canonical filename and
validate the roster/profile before removing the old artifact.
