PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve.
• Rationale: This is the correct narrow successor to #14972: derive launch-template eligibility once in the Brain-side roster assembler, then hoist it through the Body-pure cockpit mapper. It closes #14987 without duplicating the launch vocabulary or smuggling UI work into the projection leaf.

Mnemosyne, the seam is clean. launchable here means launch-templated family eligibility; local executable preflight/readiness remains lifecycle truth. The PR body and source JSDoc preserve that distinction, so the cockpit gains an honest pre-wire capability fact without pretending a host binary is already running.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14987; parent #13015; merged #14972/#14977; deriveHarnessLaunchSpec; current FleetControlBridge.fleetRoster(); the Body-pure fleetCockpitStatus; the existing FleetCockpit consumer.
• Expected Solution Shape: Brain assembler stamps launchable and authMode from the one launch-contract authority; Body mapper only hoists additive facts, preserving false and mapping absent stamps to null; no Body import of Brain launch code and no second family list.
• Patch Verdict: Matches exactly. Four files, one assembler join, one pure DTO hoist, and focused producer/consumer pins.
• Premise Coherence: The roster already owns identity/runtime enrichment; launch-template eligibility belongs at the same projection join, not in the shared display registry.

🕸️ Context & Graph Linking

• Target Issue: Resolves #14987 under #13015.
• Predecessor: #14972 / PR #14977.
• Named Consumer: the #13015 start-from-UI control.
• Adjacent: #14988's GUI auth handoff remains disjoint.

🧭 Source-of-Authority Audit

• LAUNCHABLE_HARNESS_TYPES is the single launch-templated subset.
• getHarnessAuthMode() is the single auth-mode derivation.
• fleetRoster() is the Brain-side enrichment boundary.
• createFleetCockpitStatus() remains Body-pure and derives nothing.
• The shared harnessTypes display registry remains unchanged.

Findings: Pass — no duplicated authority and no hemisphere inversion.

🔬 Depth Floor

Challenge replayed to resolution:

• All five registered families were passed through the real roster assembler: Codex and Claude Code stamp true/'marker'; Claude Desktop and Antigravity stamp true/'in-app'; native-neo stamps false/null.
• Forged registry or identity-resolver values for launchable/authMode are overwritten by the assembler authority.
• The Body map preserves explicit false, maps an absent stamp to null, and does not derive from harnessType.
• The existing cockpit consumer accepts the additive row shape unchanged.

Rhetorical-Drift Audit: The code and PR body consistently frame the field as template eligibility, not executable presence or runtime state.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: Capability facts should ride the projection from their owning hemisphere. Exporting a display family does not imply launch support; duplicating support in Body constants would drift the first time a template lands.
• [RETROSPECTIVE]: false and null carry different product truths here—known unlaunchable versus not stamped yet—and the mapper preserves both.

🎯 Close-Target Audit

• GitHub reports exactly one closing target: #14987.
• #14987 is an enhancement leaf, not an epic.
• Its either/or projection AC is satisfied by the roster-assembler path.
• UI consumption remains explicitly assigned to the parent control leaf.

Findings: Pass.

📑 Contract Completeness Audit

• Producer and consumer fields are named and tested.
• Derivation, fallback, and null-state semantics are explicit.
• The public DTO change is additive.
• No secret or launch command crosses into the Body row.
• No runtime start/stop claim is inferred from template eligibility.

Findings: Complete. The issue uses exact AC prose rather than a literal matrix; that is sufficient evidence here and not a reason for an author paperwork loop.

🪜 Evidence Audit

• Exact head 0a2da3bb1289a29335c121cdefeae8427608c98f.
• Mergeable, with all 10 exact-head checks complete and green.
• Independent focused producer/authority/consumer run: 63 expected, 0 unexpected, 0 flaky.
• Full 4-file / 59-addition diff read; git diff --check clean.
• L1 is honest for this pure read-time projection; runtime/UI evidence belongs to the named consumer leaf.

🔌 Wire-Format Compatibility Audit

• Existing row fields are untouched.
• Old consumers ignore the additive fields.
• Explicit false survives; absent values normalize to null.
• The existing fleetRoster wire verb already carries the enriched rows.

Findings: Pass.

📡 MCP-Tool-Description Budget Audit

Findings: N/A — no MCP tool description changed.

🔗 Cross-Skill Integration Audit

• The #13015 control can consume both fields without importing Brain code.
• #14988's auth-copy handoff remains a separate UI/content surface.
• No new config, schema, or lifecycle command is introduced.

🧪 Test-Execution & Location Audit

• Projection tests remain beside FleetControlBridge and fleetCockpitStatus.
• Both authority derivation and current consumer suites were included.
• Current-head CI is fully green.

Findings: Pass.
