Tom Boucher 653f95e39f chore(#2801): remove the hostBehaviors.reviewerCli deprecated alias (#3272)
* test(#2801): failing-first suite for the hostBehaviors.reviewerCli alias removal

Inverts the Phase 5a rows that assert the derived legacy alias still
contributes a reviewer slug, and adds the removal-warning coverage the
alias's exit needs (ADR-2782 D9).

RED against unmodified production code, by design: the six shipped
manifests still declare the key and collectReviewerWarnings emits nothing
for hostBehaviors.

* chore(#2801): remove the hostBehaviors.reviewerCli deprecated alias

ADR-2782 D9, Phase 7 — the final phase of epic #2782.

The derived legacy alias survived one release (Phase 5a shipped in 1.9.0;
1.9.1 and 1.10.0 have since gone out), so it goes. A declared reviewer
body is now the only route onto the reviewer roster.

- deriveReviewerSlugs no longer reads runtime.hostBehaviors.reviewerCli
- the key is stripped from the six manifests that carried it; each already
  declares a reviewer body whose slug equals its capability id, so the
  derived roster is unchanged at the same twelve slugs
- collectReviewerWarnings emits a presence-based, non-fatal removal notice
  for any manifest still declaring the key, reaching both the build-time
  registry generation and the third-party overlay load path. The check runs
  before the reviewer-body early-return, because the manifest it exists for
  is the alias-only one that has no body.
- hostBehaviors stays an open, unvalidated bag for its other 59 keys; this
  adds one keyed removal notice, not general validation

* refactor(#2801): give the reviewer-warning channel a typed IR

Review finding: the new tests asserted with String#includes() on the
warning prose, which CONTRIBUTING.md's 'Prohibited: Raw Text Matching on
Test Outputs' bans in favor of a typed intermediate representation.

Adds the IR beside the renderer rather than replacing it, which is the
shape that section prescribes and bin/verify-reapply-patches.cjs already
models:

- REVIEWER_WARNING, a frozen code enum
- REMOVED_REVIEWER_CLI_FIELD, so the emitting site and its test share one
  symbol instead of duplicating a literal
- collectReviewerWarningRecords(cap), returning typed records

collectReviewerWarnings(cap) keeps its exact string[] contract as a thin
map over the records, so both production consumers are untouched. Every
section-K row now asserts on record.code/field/capId and none on the
rendered message. Locks the code surface, asserts the renderer stays
one-to-one with the records, and migrates the pre-existing Phase 2 test
on the same channel off prose matching.

* test(#2801): invert the section F alias fall-through regression row

Caught by the remote runner: 2 unique failures on both Node lanes out of
31,692. tests/reviewer-lane-declarations.test.cjs section F — Phase 5a's
isolated-security-review regressions — asserted that a blank reviewer.slug
falls through to the hostBehaviors.reviewerCli alias rather than dropping
the lane. That is the direct inverse of this phase's contract.

The original rationale held only while the alias existed. With it gone
there is nothing to fall through to: a blank body is not a declaration,
and a declaration is the only route onto the roster.

Inverted rather than deleted — the row carries the adversarial-review
provenance for the slug trim, and removing a security regression guard to
make a change pass is backwards. The duplicate row added earlier in
section C is dropped instead; section F is its canonical home.

Also corrects two count strings Phase 5b left at eleven while asserting
twelve, which would misreport on failure.

* docs(#2801): give the removed reviewerCli flag a migration path

The Reference edit alone satisfied CI — a file under docs/ moved, so
lint-docs-required.cjs was green — while the task-oriented quadrant said
nothing about the removal. A maintainer whose lane had just gone silent
would have found the field documented as removed and no page telling them
what to do about it.

Adds a migration section to the how-to: the symptom, the verbatim warning
they will see, the before/after manifest, and the note to keep the
reviewer slug equal to the capability id so existing
review.default_reviewers entries and --<slug> flags survive.

* chore(#2801): backfill changeset pr number to 3272

* feat(#2801): close the runtime.hostBehaviors vocabulary

ADR-1016 closes twelve descriptor axes and rejects an open escape hatch
in the descriptor. It never mentioned runtime.hostBehaviors, and that
silence was read as permission: 59 keys across 18 manifests, 39 of them
set by a single capability, validated by nothing. The reference docs went
further and attributed the open seam to ADR-1016, which does not mention
the field at all.

KNOWN_HOST_BEHAVIORS enumerates the vocabulary. An undeclared key yields a
non-fatal UNKNOWN_HOST_BEHAVIOR record on the same D4.3 channel as the
alias removal notice, reaching both build-time generation and overlay
install.

Warning, never error, for the reason this phase exists: an error would
hard-break an out-of-tree descriptor carrying a bespoke key with no
deprecation window, which is what reviewerCli was given a release to
avoid. Escalation is a separate decision.

reviewerCli is excluded from the unknown-key sweep so it keeps its own
notice with the migration pointer rather than drawing two records.

A parity test binds the vocabulary to the shipped manifests in both
directions, and a second asserts no shipped capability draws a notice, so
the closure is provably inert in-tree.

Records the decision and the miscitation as an ADR-1016 amendment.

* fix(#2801): bound and sanitize the unknown-key diagnostics

Two findings from an isolated adversarial review of the closure commit,
both proven by execution rather than asserted.

MAJOR, introduced by the closure: the new Object.keys(hostBehaviors) sweep
had no ceiling. An installed third-party manifest is bounded only by
MANIFEST_MAX_BYTES, and an 8.69MB manifest with 800,000 keys produced
800,000 records and ~139MB of message text, retained for the registry's
lifetime in OverlayMeta.diagnostics. Now capped at ten records plus a
summary carrying omittedCount, mirroring capability-loader's existing
slice(0,3) idiom. The same manifest now yields 11 records and 1748 chars.

MINOR, newly reachable: manifest-supplied key names were interpolated raw.
Unlike cap.id, which validateCapability gates on KEBAB_RE before these
diagnostics run, hostBehaviors keys have no grammar check anywhere, so
ANSI escapes and CRLF reached stderr and OverlayMeta.warnings intact. New
describeKey replaces C0/C1 controls and clips at 80 chars. The file
already had describeValue for this and applied it only to values.

Both fixes land on the pre-existing reviewer.* sweep too — it carried the
identical pair, and fixing only the new copy would leave the same defect
one screen from its own fix.
