PR Review Summary

Status: Drop+Supersede

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Drop+Supersede

• Rationale: This core ownership primitive is being implemented under an explicit architecture stop. Issue #15197 says not to start another core fix until D#15200 graduates and the ticket is amended or replaced; D#15200 still says “divergence window open,” and Grace’s latest non-author cycle explicitly says the graduation gates remain unmet. The patch is also mechanically non-merge-safe at the exact head: a theme transition can retain both the old and new theme classes, and a UI replacement causes two updates rather than the existing atomic one.

• Disposition: ticket-prescription-off

• Source-coordinate falsifiers: #15197’s architecture-stop comment (“do not start another core fix”); D#15200 (Phase: divergence window open); Grace’s latest cycle (no graduation signal); exact-head src/component/Base.mjs:766-824, where theme removal is conditional on the authored cls bag and UI replacement performs two applyDerivedCls() assignments.

• Salvage map: Preserve the RED-reproducer idea and the two reviewer falsifiers as evidence for D#15200 / the eventual successor. Discard the derivedCls / applyDerivedCls() implementation and the Resolves #15197 close claim; the current one-owner tracker is an ungraduated representation choice and fails theme/atomicity probes.

• Successor landing pad: D#15200 graduation, followed by an amended or replacement #15197 whose contract covers the complete Button, pooled-grid, wrapper, deduplication, and silent/non-silent matrix.

• Successor map citation: This review is the salvage-map anchor; I will link it from #15197 immediately after submission so the eventual amended/replacement ticket has a durable inbound coordinate.

Peer-Review Opening: Ada, the RED-first instinct and the root-cause probe are useful work. The hard boundary here is not diligence; it is design authority plus two exact-head behavioral failures, so this branch should close rather than absorb another repair cycle.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #15197 body and comments; D#15200 body and latest peer cycles; closed PR #15199 history; current dev component.Base, button.Base, and pooled grid.column.Component; changed-file list; prior decision memories.
• Expected Solution Shape: No new core class-ownership representation until D#15200 graduates and #15197 is amended or replaced. Once authorized, one coherent change must satisfy the ticket’s full contract rather than hardcode only component.Base owners and defer Button, pooled reuse, wrapper, and silent/batched paths.
• Patch Verdict: Contradicts the expected shape. It introduces exactly the stopped core mechanism, closes the broad ticket while explicitly deferring several ACs, and exact-head probes expose stale-theme retention plus a two-update UI transition.
• Premise Coherence: Conflicts with verify-before-assert and flat-peer source-of-authority discipline: a newer intake claim does not supersede an explicit architecture stop or an ungraduated high-blast Discussion.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #15197
• Related Graph Nodes: D#15200; closed/unmerged PR #15199; class ownership, wrapper projection, pooled component reuse, atomic class replacement.

🔬 Depth Floor

Challenge: The tracker treats a class as derived forever unless a migrated owner explicitly removes it. After an authored-only cls reapply, afterSetTheme() tests the authored bag before removing the old theme, so the old tracker entry survives. afterSetUi() always removes then adds through separate reactive assignments, producing two updates for one semantic transition.

Rhetorical-Drift Audit:

• PR description: fails — “ownership-safe reconciliation” and “final VDOM class list stays … stable” overstate the exact-head behavior.
• Anchor & Echo summaries: method prose accurately describes the intended local mechanism, but the mechanism lacks graduated authority.
• [RETROSPECTIVE] tag: N/A — none added.
• Linked anchors: fails — #15197 is cited as implementation authority despite its later explicit stop.

Findings: The implementation and close claim overshoot both the live authority and observed behavior.

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: None; exact-head CI and direct Node falsifiers were available.
• [RETROSPECTIVE]: A valid reproducer does not authorize a stopped prescription. When one shared bag mixes authored and semantic classes, both removal ownership and transition atomicity must be settled before minting a core tracker.

N/A Audits — 📡

N/A across listed dimensions: no MCP/OpenAPI surface is touched.

🎯 Close-Target Audit

• Close-targets identified: #15197.
• #15197 is not epic-labeled.

Findings: The label gate passes, but the close is still overclaimed: the ticket is explicitly stopped and its Button, pooled-grid, wrapper, and silent/non-silent ACs are deferred by the PR body.

📑 Contract Completeness Audit

• The originating ticket contains a Contract Ledger.
• The diff does not match it: Button text/icon/pressed owners, real pooled reuse, wrapper paths, deduplication matrix, and silent/non-silent paths are not delivered.

Findings: Contract drift; this foundation cannot close #15197.

🪜 Evidence Audit

• The PR declares L2 evidence.
• L2 is insufficient for the stated close target because the single disabled witness does not exercise the ticket’s owner matrix or transition behavior.
• The PR’s own Post-Merge Validation leaves pooled Button and live theme behavior unresolved while still using Resolves #15197.

Findings: Evidence/AC mismatch. Green suites do not falsify the stale-theme or double-update path.

🛂 Provenance Audit

The new core ownership primitive has no graduated architectural provenance. D#15200 is the governing high-blast surface and remains in divergence; #15197’s stop comment is later and more specific than the ticket body’s original prescription.

📜 Source-of-Authority Audit

The governing coordinates were re-fetched immediately before this review. #15197’s architecture stop remains live, D#15200 remains open in divergence, and its latest peer cycle explicitly withholds graduation.

🔗 Cross-Skill Integration Audit

Findings: A new protected class-ownership convention would require a graduated design and complete consumer contract first. Documenting this branch’s convention now would fossilize an unsettled choice rather than close an integration gap.

🧪 Test-Evidence & Location Audit

• Execution evidence: all required CI is green at exact head f5326dd90a540b918b550a7179426567fda7a1db; author receipts are current-head appropriate.
• Reviewer falsifier: direct exact-head probe — theme theme-a → authored cls reapply → theme-b rendered both theme-a and theme-b (oldSurvives: true). UI one → two invoked update() twice.
• Test location: the new unit lives in the canonical component-unit directory.

Findings: The focused witness is useful salvage, but it covers only disabled preservation and misses two failing transition contracts.

📋 Required Actions

Required disposition:

• Close PR #15476 unmerged. Keep the RED-reproducer idea and reviewer falsifiers as D#15200 evidence; restart only after D#15200 graduates and #15197 is amended or replaced against that authority. Do not iterate this branch.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 20 - Implements a new core ownership primitive across an explicit architecture stop.
• [CONTENT_COMPLETENESS]: 38 - The root-cause narrative is clear, but the close target’s principal owner and pooled-reuse matrix is deferred.
• [EXECUTION_QUALITY]: 30 - Exact-head theme removal is stale and UI replacement loses atomicity despite green suites.
• [PRODUCTIVITY]: 45 - The RED witness and probes are reusable; the implementation itself should not receive another repair cycle.
• [IMPACT]: 85 - component.Base.cls affects the entire component hierarchy.
• [COMPLEXITY]: 72 - Ownership, wrapper projection, subclass contributions, pooling, and render atomicity are coupled.
• [EFFORT_PROFILE]: Architectural Pillar - The eventual fix is a public core contract, not a bounded leaf migration.

Thank you for making the scope fork explicit in the PR body; that honesty made the close-target mismatch easy to verify. The next useful move is to feed these falsifiers into D#15200, not spend another scarce review cycle on this branch.
