PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: The ticket's isolation premise is valid, but the evidence showed the journey had already selected an empty real bridge; the product guard was discarding that selection. Encoding source-selection provenance on the bridge is simpler and more truthful than adding a test-only roster backdoor or a second registry profile, while preserving the intentional zero-setup sample path.

Peer-Review Opening: Phoebe, this is a strong diagnosis-driven repair: the source journey now gets the true empty fleet it deliberately selected, without blanking the sample flagship for ordinary first boot.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #15680; the four-file changed list; current dev source for ViewportController, FleetCockpit.loadRoster, installFleetBridge, apps/agentos/app.mjs, and the authenticated journey harness; provider-hosted FleetRoster precedent; the mandatory Neo / Base / state.Provider / data.Model / data.Store app contracts; Memory Core/KB prior-art sweep; exact-head CI.
• Expected Solution Shape: Source selection must be explicit at the real App-Worker bridge injector, carried without changing the wire-operation surface, and consumed only by the first-empty admission guard. The default packaged/direct boot must remain unselected so the honestly labelled sample first paint survives; the existing provider-hosted FleetRoster Store of FleetAgent records must remain the sole data path.
• Patch Verdict: Matches. ViewportController.wireFleetBridge stamps selected: true; installFleetBridge publishes that fact as non-enumerable metadata defaulting to false; FleetCockpit admits a first empty snapshot only when selected (or under its existing source-mode/wired rules); app.mjs never opts in.
• Premise Coherence: Coheres with verify-before-assert and the Body↔Brain boundary: the UI renders the source the operator/test actually selected, while cold boot remains fail-closed on its sample authority. It also honors friction→gold by repairing the product seam exposed by a journey instead of weakening the journey.

🔬 Depth Floor

Challenge: Hosted CI does not run the named AgentOS E2E, and the new checked-in unit proves installFleetBridge can stamp selected but does not permanently bind both production glue legs. I therefore ran exact-head executable probes: ViewportController.wireFleetBridge returned true and installed a non-enumerable/non-writable selected: true; FleetCockpit.loadRoster preserved sample state for an unselected empty bridge but produced {cleared:1, adapter:'live', rosterWired:true, source:'selected'} for the selected twin. The three owner suites also passed 100/100. A dedicated injector assertion plus a bridge.selected: true empty-roster unit would improve future CI localization, but the exact-head behavior is already established by these probes and the author's L3 journey receipt, so this is non-blocking coverage refinement rather than deferred correctness debt.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: “explicit injector = source selection; default boot = sample authority” matches all known call sites and the diff.
• Anchor & Echo summaries: installFleetBridge and loadRoster describe the durable selection/admission distinction rather than ticket-cycle mechanics.
• [RETROSPECTIVE] tag: N/A — none added.
• Linked anchors: #15680 carries the two-run host-state failure and the accepted isolation boundary.

Findings: Pass.

🧠 Graph Ingestion Notes

• [KB_GAP]: “Reachable empty source” is not one state: an unselected fresh registry preserves the sample flagship, while an explicitly selected empty registry is authoritative zero.
• [TOOLING_GAP]: My exact-head E2E retry failed before app startup because the host hit repeated Watchpack EMFILE errors and Chrome exited SIGABRT; this does not falsify product behavior. The author’s exact-head 1/1 journey plus full AgentOS E2E receipt remains the L3 browser evidence.
• [RETROSPECTIVE]: Admission guards need provenance, not inference. The same empty payload can mean “default source not initialized” or “chosen fleet contains zero residents”; a one-bit owner-stamped fact preserves that distinction.

🧩 App-Work Contract Audit

• The Fleet cockpit continues to host one Neo.data.Store of FleetAgent model records through its root state.Provider.
• No hand-mapped replacement array, leaf provider, parallel store, or test-only data backdoor is introduced.
• No CSS-in-JS or styling mutation is introduced.
• Source-selection provenance stays on the bridge boundary and does not leak credentials or become a wire operation.

Findings: Pass.

🎯 Close-Target Audit

• Close-targets identified: #15680.
• #15680 is labeled bug, ai, and testing; it is not an epic.

Findings: Pass.

📑 Contract Completeness Audit

• #15680's ACs define the consumed behavior: green on a non-empty host, explicit isolation, unchanged product assertions, and use of the real bridge seam.
• The diff matches those ACs: the existing journey's real injector becomes the explicit selection authority; no assertion or registry isolation contract is weakened.

Findings: Pass. The ticket predates the matrix-form ledger convention, but no behavioral contract row is absent or drifting.

🪜 Evidence Audit

• PR body contains an Evidence: declaration and distinguishes L3 rendered behavior from the stale visual-golden residual.
• The author ran the exact failing journey 1/1 and the full AgentOS E2E directory on the loaded host that originally produced the false red.
• Reviewer owner suites passed 100/100 and direct exact-head probes bound injector provenance to first-empty admission.
• The stale cockpit-default-shell visual is explicitly scoped as pre-existing and does not arise on the selected injector path.

Findings: Pass.

N/A Audits — 📡 🔗 🔌

N/A across listed dimensions: no MCP description, skill convention, external wire envelope, database schema, or cross-skill trigger changes.

🧪 Test-Evidence & Location Audit

• Execution evidence: all 11 required hosted checks are green at exact head 492b79fc2e37c4d1776f1dacd7fdbe31ab00bef6; author receipts cover 13/13 bridge units, the named 1/1 journey, and the full AgentOS E2E directory.
• Reviewer falsifier: three owner specs passed 100/100; direct injector probe produced {ack:true, selected:true, enumerable:false, writable:false}; direct first-empty probe preserved sample when false and rendered live zero when true.
• Test location: the bridge metadata witness sits with installFleetBridge; existing Viewport/FleetCockpit suites own the two glue legs.

Findings: Pass. The local browser-launch failure was pre-app host exhaustion, not a product assertion failure.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 98 - Selection authority is stamped at the product injector, carried beside existing bridge facts, and consumed at the one admission guard that needs it.
• [CONTENT_COMPLETENESS]: 96 - Default, selected, empty, populated, and existing source-mode paths remain coherent; only optional permanent glue localization could improve.
• [EXECUTION_QUALITY]: 97 - Minimal 32-line delta, green exact-head CI, 100 owner units, direct falsifiers, and author L3 journey coverage.
• [PRODUCTIVITY]: 98 - Replaces a test-isolation workaround with one reusable product semantic and no parallel substrate.
• [IMPACT]: 91 - Restores reliable AgentOS journeys on real maintainer seats and makes explicit empty fleets render truthfully.
• [COMPLEXITY]: 42 - Small code change across a subtle sample/live/source-precedence boundary.
• [EFFORT_PROFILE]: Maintenance - Focused source-provenance and admission-guard correction.

The exact head is approval-ready. The next useful polish is a permanent two-leg unit witness, but current behavior and architecture are independently established.
