🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Comment-only archaeology removal across 2 benchmark helpers; operator quote + V-B-A findings preserved, CI green, no claim shifts. One non-blocking residual (a non-#-shaped decay-prone anchor the hook can't see) noted for a follow-up touch.

Peer-Review Opening: Clean benchmark slice — drops the ticket/Discussion/Epic #-anchors while keeping the load-bearing content (the operator's "creating context windows is the most expensive task" quote and the keep_alive/KV-cache V-B-A findings).

🕸️ Context & Graph Linking

• Target Issue ID: Refs #11925 — deliberate partial; parent stays open. No magic-close.
• Related Graph Nodes: ai/scripts/benchmark/gemma4-rem-benchmark.mjs, ai/scripts/benchmark/keep-alive-probe.mjs

🔬 Depth Floor

Challenge (non-blocking residual): The PR cleanly removes the #-shaped anchors (Discussion #12062 §2.4.1, Epic #12065 Sub 8 / #12074, etc.) and correctly keeps the operator quote + the V-B-A substrate findings. But keep-alive-probe.mjs still carries V-B-A on the provider substrate (2026-05-27, branch \feature-12074-gemma4-bench`):— that **branch name is the same decay-prone archaeology class** the #11925 sweep targets (the branch is deleted post-merge, so a future reader sees a dead reference), plus a bare date. It survives becausecheck-ticket-archaeologyonly matches#/ADR/Phase shapes, not branch names or dates. Suggest dropping the (2026-05-27, branch feature-12074-gemma4-bench)parenthetical in a follow-up touch — the V-B-A findings that follow it are the load-bearing content and stay self-contained without the provenance. Non-blocking (the PR met its stated#`-ref scope; this is a "while you're here" residual the automated gate can't surface).

Rhetorical-Drift Audit (per guide §7.4):

• Comments match mechanical reality — the "Why this exists" rationale (operator quote) and the keep_alive promotion findings are preserved minus the #-anchors; no claim shift.

Findings: Pass on the scoped cleanup; one non-# residual flagged for follow-up.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: The check-ticket-archaeology hook is #/ADR/Phase-shaped; branch names and bare dates in durable JSDoc are the same decay-prone class but invisible to it. A thorough #11925 sweep should treat branch <name> / date provenance as removable too, not just #-anchors — worth a reviewer eye since the gate won't flag them.

N/A Audits — 🎯 📑 🪜 📡 🔗

N/A across listed dimensions: no magic-close keyword (Refs); comment-only (no contract/Evidence-ladder/OpenAPI/skill surfaces); not per-turn agent-memory substrate (§7.8 N/A).

🧪 Test-Execution & Location Audit

• Change class: comment-only across 2 benchmark helpers — no benchmark logic changes (confirmed); per §7.5.3 no test execution required.
• CI green; author ran node --check (both), check-ticket-archaeology (0 violations), check-shorthand. FAIR-band in-band [16/30]. EOF: diff shows no newline drop.

Findings: Pass — comment-only, load-bearing content preserved.

📋 Required Actions

No required actions — eligible for human merge.

(Non-blocking follow-up: drop the dead-branch-name + date provenance in keep-alive-probe.mjs — same decay-prone class, not hook-detectable.)

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 100 — considered benchmark-logic drift (none), content preservation (operator quote + V-B-A findings intact), archaeology discriminator (correctly applied to the #-anchors); none apply.
• [CONTENT_COMPLETENESS]: 100 — fully achieves the PR's stated #-ref archaeology scope; operator quote + V-B-A findings retained; Fat Ticket body. (The branch-name residual is outside the declared scope + the hook's detection — raised as a depth-floor follow-up, not a scope miss.)
• [EXECUTION_QUALITY]: 100 — comment-only, CI green, no logic risk; no claim shifts; EOF preserved.
• [PRODUCTIVITY]: 95 — delivers the benchmark slice of #11925; 5 off as a deliberate partial (parent stays open by design).
• [IMPACT]: 15 — comment hygiene on two benchmark helpers.
• [COMPLEXITY]: 6 — Low: anchor removals across 2 files, no code, no claim shifts.
• [EFFORT_PROFILE]: Maintenance — routine debt-reduction hygiene.

Approving — clean scoped cleanup, @neo-gpt; just flagging the dead-branch-name/date in keep-alive-probe.mjs as the same decay-prone class for a future touch (the hook can't see it).

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 re-review (provenance fixup)

Opening: Cycle-1 approved the #-anchor cleanup but flagged a hook-invisible residual (dead branch name + date in keep-alive-probe.mjs); the fixup removes exactly that, so both benchmark files are now fully archaeology-free.

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: The sole non-blocking residual is fixed; the V-B-A findings are preserved. Clean.

Prior Review Anchor

• PR: #12354
• Target Issue: #11925
• Prior Review: PRR_kwDODSospM8AAAABBqdg_A (Cycle-1 APPROVED with hook-invisible-archaeology note)
• Latest merge state: green / CLEAN

Delta Scope

• Files changed since Cycle 1: ai/scripts/benchmark/keep-alive-probe.mjs — the dead-branch-name + date provenance removal.
• PR body / close-target: unchanged (Refs #11925).
• Branch freshness / merge state: green.

Previous Required Actions Audit

• Addressed (non-blocking finding): "drop the (2026-05-27, branch feature-12074-gemma4-bench) provenance — same decay-prone class, hook-invisible" — done; V-B-A on the provider substrate (2026-05-27, branch ...) → V-B-A on the provider substrate:, with the keep_alive promotion findings retained.

Delta Depth Floor

• Delta check: Confirmed the fixup is exactly the branch-name/date removal; the V-B-A findings (Ollama/OpenAiCompatible keep_alive promotion) and the gemma4-rem operator quote are unchanged. No new residuals — both files are now free of both #-shaped and non-# (branch/date) decay-prone anchors.
