PR Review Summary

Status: Approved

Cycle-1 reviewers: run §9.0 Premise Pre-Flight BEFORE composing Required Actions. If any structural trigger fires (premise-invalid / upstream-not-graduated / author-bypassed / anti-pattern / strategic-misalignment / better-existing-substrate / source-ticket-stale/currency-risk), default to Drop+Supersede framing — single-item close-recommendation, NOT multi-item iteration list.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Premise Pre-Flight passes cleanly. Source authority is Discussion #11577 graduation (DC_kwDODSospM4BAt-P) + #11584 AC2. The Signal Ledger is comprehensive — 3-family signals cited with timestamps + operator-liveness-override-rationale for degraded Gemini harness. ADR rewrite preserves ADR 0007's compaction taxonomy as historical authority + names #11577 as the corrected-substrate authority + cites #11584 as the cleanup vehicle. Net byte delta is -4 lines (substrate-cap-aware) which honors the Map vs World Atlas discipline this PR is restoring. Slot Rationale present + correctly classifies disposition as rewrite stale worked-example policy into corrected substrate contract.

Peer-Review Opening: Clean ADR rewrite — restructures §2.1 from manual-HTML-anchor mandate to §<ref> text-token primitive without losing the underlying semantic-stability intent. The Acceptable Variants block (§21 + §mailbox-check-protocol both valid) directly substantiates operator's "every anchor tag instead of § is damage" framing while preserving positional-ref legitimacy. Signal Ledger handling of the stale-Gemini-signal + operator-override is exactly the §6.1.1 Consensus-Gate pattern.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Refs #11584 (delivers AC2 / Lane B; non-finalizing)
• Related Graph Nodes: Discussion #11577 (graduation authority), #11571 (damage PR — companion revert in PR #11588), companion lane PRs #11588 (Lane A revert) + #11586 (Lane C lint inversion), ADR 0007 (preserved as historical authority)

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

Three non-blocking observations as graph-ingestion follow-up surfaces:

• Challenge 1 — §3.4 rationale shift: the prior "Why explicit anchors instead of generated heading anchors" rationale (renderer-dependence anti-coupling) is replaced with "Why text tokens instead of markdown links" (byte-budget). Both are valid but the new §3.4 is silent on the prior anti-coupling concern. §2.2 implicitly endorses auto-generated heading IDs ("Prefer auto-generated heading IDs..."), which IS renderer-dependent. Defensible scope-bounded choice — the corrected substrate accepts a partial renderer-dependence trade for byte savings — but worth a comment in ## Consequences noting the trade-off was made knowingly.

• Challenge 2 — §5.2 anti-pattern restatement: "Do not choose a semantic §<ref> token that merely mirrors volatile heading prose." Reasonable, but "volatile" is unspecified. A short example would tighten the guidance — e.g., "Avoid §the-cross-family-mandate-2026-05 over §cross-family-mandate." Non-blocking but graph-extractable.

• Documented search: I actively looked for (1) closingIssuesReferences state — verified [] at PR-open (substrate-pattern feedback_partial_lane_pr_close_target Cycle-2 discipline applied correctly from open; close-verb proximity to #11584 is reverse-order in §6 V-B-A item line so doesn't trigger GitHub's auto-link regex), (2) interaction with companion PR #11586 lint scope — §2.4 enforcement language ("Block new manual HTML anchor-tag insertions in Map / skill / Agent OS substrate") matches my Lane C ANCHOR_TAG_PATTERN scope exactly; cross-PR coherence verified, (3) ADR 0007 baseline preservation — confirmed Supersedes field changed but ADR 0007 reference retained as historical-authority anchor (not rewritten), (4) Slot Rationale shape — disposition delta + 3-axis rating + decay-mitigation all present per pull-request-workflow.md §1.1.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing accurate. "ADR no longer presents manual HTML anchor tags plus markdown-link payloads as the default" exactly matches the diff (§2.1 worked example replaced with §<ref> token form).
• Anchor & Echo: ADR header summary updated to compact §<ref> form — precise terminology, no overshoot.
• [RETROSPECTIVE] tag: N/A.
• Linked anchors: Discussion #11577 + #11584 + ADR 0007 + ADR 0005/0006 citations all valid + appropriately scoped.

Findings: No drift. Two non-blocking observations recorded above.

🧠 Graph Ingestion Notes

• [KB_GAP]: N/A.
• [TOOLING_GAP]: N/A.
• [RETROSPECTIVE]: ADR amendment shape that worked here: preserve historical-authority anchor (ADR 0007), name the correcting Discussion (#11577) + cleanup ticket (#11584) explicitly in ## Related, restructure the worked example without rewriting the underlying historical decision sequence. The pattern is replicable for future ADR amendments where a downstream Discussion supersedes a prior ADR's worked-example primitive.

N/A Audits — 🛂 📑 📡 🔌 🧪

N/A across listed dimensions: docs-only ADR amendment with no architectural abstraction surface, no public/consumed contract change, no MCP OpenAPI surface, no wire-format change, no executable tests required (static markdown content; lint-pr-body + check-substrate-size + check-whitespace already passed per PR body Test Evidence).

🎯 Close-Target Audit

• Close-targets identified: Refs #11584 (non-magic) — gh pr view 11589 --json closingIssuesReferences returns []. Partial-lane discipline applied correctly from PR-open per feedback_partial_lane_pr_close_target memory.
• For each #N: confirmed #11584 not epic-labeled.
• §6 V-B-A checklist item line "verify #11584 can be resolved only by the final-lane / operator-disposition path" uses reverse word-order (#11584 precedes verb resolved); does not trigger GitHub's auto-link regex which expects keyword #N order.

Findings: Pass.

🪜 Evidence Audit

• PR body contains an Evidence: declaration line — Evidence: L1 (static ADR/source contract audit) → L1 required (doc-substrate policy correction; no runtime-observable ACs). Residual: #11584 remains open for companion lane completion and operator disposition.
• L1 is the correct ceiling for ADR amendment (no runtime behavioral surface; static markdown contract). No L2+ promotion drift.
• Residual explicitly named (companion lane completion + operator disposition) — correctly flags the open scope.

Findings: Pass.

📜 Source-of-Authority Audit

• Signal Ledger cites specific commentIds for each 3-family signal: DC_kwDODSospM4BAssw (Gemini), DC_kwDODSospM4BAt9H (GPT corrected), DC_kwDODSospM4BAt-P (Opus final).
• Operator-authority citation is via DC_kwDODSospM4BAt-P paraphrase — marked as paraphrase per feedback_peer_cited_authority_neutral_ask discipline. Operator-liveness-waiver explicitly attributed.
• Substantive demands stand on substrate merits (Discussion #11577 graduation + ADR 0007 compaction discipline), not on authority alone.
• No appeal-to-authority compounding.

Findings: Pass.

🔗 Cross-Skill Integration Audit

• Substrate-mutation pre-flight gate (pull-request-workflow.md §1.1): PR touches learn/agentos/ — slot-rationale section present with disposition delta + 3-axis rating + decay-mitigation. Verified.
• Cross-PR coherence: §2.4 enforcement language aligns with PR #11586 Lane C ANCHOR_TAG_PATTERN scope (Map / skill / Agent OS substrate). ADR + lint co-evolve cleanly.
• No new convention introduced (ADR amends existing convention); no skill-router update needed.
• Companion lanes naturally absorb the post-merge substrate: future PRs author per ADR 0011 corrected form + lint catches <a id> regression at CI.

Findings: Pass.

🛡️ CI / Security Checks Audit

• Ran gh pr view 11589 --json statusCheckRollup to empirically verify CI status.
• lint-pr-body SUCCESS at review time. Analyze (javascript) / integration-unified / unit checks pending — docs-only PR, these are not gating (no code path changed).
• PR body Test Evidence section transparently documents the static checks already run by author: lint-agents.mjs --base HEAD pass, check-substrate-size.mjs pass, check-whitespace.mjs pass, rg confirmation that no <a id> / <a name> patterns remain in the file.

Findings: Pass — lint-pr-body green; remaining CI checks are not gating for docs-only PR.

📋 Required Actions

No required actions — eligible for human merge.

Optional follow-ups (post-merge, file separately if pursued):

• Add a ## Consequences note acknowledging the §3.4 trade-off (text-token form accepts partial renderer-dependence via auto-generated heading IDs in exchange for byte savings).
• Tighten §5.2 anti-pattern with a worked example of "volatile heading prose" vs. stable semantic token.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 100 - ADR rewrite preserves ADR 0007 historical authority + cites #11577 + #11584 as correcting authorities + Slot Rationale + Signal Ledger + Close-target discipline + FAIR-band all correctly applied. Cross-PR coherence with #11586 lint scope verified.
• [CONTENT_COMPLETENESS]: 100 - PR body has Signal Ledger / Unresolved Dissent / Unresolved Liveness / Slot Rationale / Test Evidence / Deltas / Post-Merge Validation. Maps to #11584 AC2 verbatim.
• [EXECUTION_QUALITY]: 95 - 1 file, 40+/44−, net -4 lines (substrate-cap-aware). Mechanically clean. 5-point reservation for the two non-blocking observations in Depth Floor.
• [PRODUCTIVITY]: 100 - Single-cycle approval-eligible. Partial-lane discipline applied correctly from open (no Cycle-N close-target churn like my #11586 / #11588 hit).
• [IMPACT]: 60 - Doc-substrate policy correction; affects future ADR-touching PRs + cross-PR coherence with lint enforcement. Foundational for the corrected substrate discipline going forward.
• [COMPLEXITY]: 30 - Small surface (1 file, ~84 lines changed), well-isolated scope.
• [EFFORT_PROFILE]: Quick Win - Targeted ADR amendment delivering AC2 cleanly + closing the operator-corrected-substrate trifecta with PR #11588 + #11586.

Ship it. Three-PR substrate-cleanup arc converges naturally now — once #11588 + #11586 + #11589 all merge, #11584 fully completes via operator disposition or final-lane PR convention.
