Fallout from ward#289 (add a doc_goal: front-matter line to every ward doc so it grades against an explicit target).

Problem

The pinned agentic-os documentation-layout hook (check_documentation_layout.py, check_markdown_sizes) counts the whole file against the 4000-char / 80-line flat cap, including YAML front-matter. Nearly every ward doc is authored right at the ceiling (3800-3999 chars, 74-80 lines), so the 3-line doc_goal front-matter block (metadata the grader itself strips before reading) tips ~50 docs over the cap even though not one line of prose grew.

Bridge shipped in ward#289

To land the doc_goal rollout without --no-verify and without trimming real prose to make room for metadata, ward#289 added the 50 overflow docs to [tool.agentic-os.documentation-layout].excludes in pyproject.toml, in a clearly-marked ward#289 bridge block. That disables the size cap for those docs, which is a real (temporary) guardrail loss.

Proper fix (this issue)

Exempt YAML front-matter from the size count in the upstream agentic-os check_documentation_layout.py - strip a leading ---...--- block before len(text) / splitlines(), exactly as the grader's parse_frontmatter and the hook's own blank-line rule already treat non-prose lines. Front-matter is metadata, not prose, and should not eat the prose budget. Then bump the ward managed-hook pin and delete the ward#289 bridge excludes block, restoring the cap for all 50 docs.

🔒 Reserved by ward agent --driver claude — container engineer-claude-ward-556 on host KAI-DESKTOP-TOWER is carrying this issue (reserved 2026-07-04T08:28:50Z). Concurrent ward agent runs are blocked until it finishes or the reservation goes stale (2h0m0s TTL); --force overrides.

Do not comment on or edit this issue to steer the run while it is reserved. The engineer seeded the body once at launch and never re-reads it, so a comment or edit reaches only human readers, never the running engineer. A correction goes to a new issue, dispatched fresh — that is the only channel that reaches a run in flight. Where the forge supports it, ward locks this conversation to make that a road-block rather than a convention (ward#494).

WARD-OUTCOME: blocked - this is a cross-repo change and agentic-os was not granted to this ward-only container; the frontmatter-strip must land + release in agentic-os before ward's pin can bump. Also: only 32 of the 50 bridged docs are frontmatter-overflow — 18 are genuine prose-overflow and can't be un-excluded by this fix.

Carried this end-to-end as far as the wall allows and stopped where doctrine says to. Two things blocked a clean landing, and the second is the interesting one.

1. It's cross-repo, and only ward was granted. The proper fix edits check_documentation_layout.py, which lives in agentic-os (read-only under /substrate, not a /workspace grant). The pin bump is release-gated on that: ward pins v0.167.0, the fix is in no released agentic-os (latest v0.180.0), so bumping alone rescues nothing. To land this: grant coilyco-flight-deck/agentic-os (ward agent … --repo coilyco-flight-deck/agentic-os) and re-dispatch, or land+release the upstream fix separately, then re-dispatch the ward side.

2. The issue's premise is only ~64% true — I verified this empirically. I ran a patched copy of the real hook against ward's tree. The frontmatter-strip (validated, mirrors check_skill.parse_frontmatter) rescues 32 of the 50 bridged docs. The other 18 are over the flat cap on prose alone — they grew during ward#289's "lift the under-sellers" pass while the exclude had the gate off. So "not one line of prose grew" is false for these, and "delete the whole block" would red the pre-commit for all 18:

FEATURES.md (18315c, cap 12500), agent-advisor (87L/5136c), agent-preflight (4636c), agent-reservation (90L/4899c), agent (97L/4916c), broker (107L/5946c), comparison-openshell (82L/4811c), container-api (4190c), container-env (85L/5612c), container-multi-repo (119L/6993c), container-reap (86L/5011c), container (83L/4247c), doctor (5062c), exec-verb (86L/4366c), git-verbs (99L/4292c), ops-forgejo (92L/4841c), release (144L/8397c), ward-kdl-surface (4569c) — all measured after stripping frontmatter. For context, each was at 3994/3990/3998… (right at the ceiling) before ward#289.

The verified upstream patch (agentic_os/pre_commit/check_documentation_layout.py), a helper before check_markdown_sizes, called on the text it sizes:

def strip_frontmatter(text: str) -> str:
    """Drop a leading ---...--- YAML front-matter block before sizing.
    Metadata (e.g. the doc-grader's doc_goal:) is not prose and must not eat
    the budget. Mirrors check_skill.parse_frontmatter's leading-fence detect."""
    if not text.startswith("---\n"):
        return text
    end = text.find("\n---", 4)
    if end == -1:
        return text
    body_start = end + len("\n---")
    if text[body_start : body_start + 1] == "\n":
        body_start += 1
    return text[body_start:]
# then in check_markdown_sizes:
#   text = strip_frontmatter(path.read_text(encoding="utf-8", errors="replace"))

Suggested re-scope for the ward side once the upstream release exists: bump the pin, delete only the 32 frontmatter-only entries, and either trim/split or keep-with-corrected-comment the 18 prose-overflow docs as a separate tracked cleanup (the current block's "not one line of prose grew" comment is wrong for them). Left ward's tree clean — nothing half-landed for the reaper to guess at.

Confidence high on the diagnosis and the patch (both empirically run against ward's actual docs); the only judgement call is whether the 18 get trimmed or permanently carved out, which is a human call.

Correction. The preceding "Relabeled headless->consult" comment is inaccurate - the relabel did NOT apply, and this issue still carries headless. This container's Forgejo write path routes through a broker that serves only the issue write tier (create / edit / comment / close / reopen); issue-label add/remove is out of tier and was refused. The headless->consult relabel is deferred to a surface (or role) that holds the issue-label tier - or requires the broker's write tier to include issue-label. Tracked back on ward#621.
