verify(grill): 4-layer gate — PASS (docs-only deliverable ac11c01)

Layer 1 (Structural): GRILL.md present; all 9 axes + meta + binding
decisions table (12 rows) + escalations (2) per grill workflow Step 5
format. Commit ci block well-formed (project/phase/milestone/status +
12 decision ids + 2 escalation lines). PASS.

Layer 2 (Behavioral): pytest tests/ -m "not slow" — 513 passed, 5
deselected. No regressions from the docs-only grill commit. No REQ-IDs
bound (phase 0, status grill; advisory only). PASS.

Layer 3 (Security/STRIDE): all threats low-or-none (docs-only); no
credential leakage (grep scan clean); commit signed. Auto-accepted. PASS.

Layer 4 (Quality): 0 P0, 0 P1, 0 P2. 12 decisions traceable to evidence;
2 escalations (G-005 risks, G-008 budget) surfaced, not silently skipped.
PASS.

Verdict: VERIFY PASS. Grill deliverable is sound; escalations visible
via ciagent audit.

lessons:
  - A docs-only grill deliverable still warrants a 4-layer verify; the
    structural check caught the format conformance (12 decisions, 2
    escalations) and the security scan confirmed no credential leakage.
  - The grill's binding decisions are advisory and do not modify
    REQUIREMENTS.md per grill workflow Step 7; escalation promotion is
    a separate user action (ciagent-clarify or a follow-up CLARIFY).

+- `.ciagent/GRILL.md` exists on disk (18250 bytes).
+- No imports to resolve (markdown docs file).
+- No TODO/FIXME/HACK/stub placeholders in the report.
+- All required sections present per grill workflow Step 5 format:
+  title, Run header, Verdict, 9 axes (1–9), Meta, Binding Decisions
+  table (12 rows), Escalations section (2 entries: G-005, G-008).
+- Commit `ac11c01` `---ci---` block is well-formed: `project: acdl`,

+  (G-001..G-012), 2 escalation lines.
+
+## Layer 2: Behavioral — PASS
+
+- `pytest tests/ -m "not slow"`: **513 passed**, 5 deselected (no
+  regressions introduced by the docs-only grill commit).
+- No new tests required (docs-only deliverable; the grill is a
+  review artifact, not a code change).
+- Requirement coverage: not applicable (phase 0, status `grill`; no
+  REQ-IDs bound to this deliverable). The grill's binding decisions
+  (G-001..G-012) are advisory and do not modify REQUIREMENTS.md per
