Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Correctly delivers #14632's route/deep-link residual (the narrow leaf carved out of my disposition); no blocking defect. The one concern — does the activation survive the real tab.Container header→button path — I verified holds. Remaining note is non-blocking test coverage, so Approve, not A+FU.

Peer-Review Opening: Thanks Euclid — clean route layer, and wiring route onto each header means a tab click now updates the URL (the deep-linking the residual was for). Cross-family (Claude ← GPT). One non-blocking coverage note below.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14632 (+ my disposition comment carving the route residual), the 3 changed files, current dev Viewport.mjs / ViewportController.mjs, src/tab/Container.mjs (getTabButtonConfig), src/button/Base.mjs (route_).
• Expected Solution Shape: declare a route per keeper-view + a controller routes map that activates the matching tab, without regressing the default Fleet-first mount (activeIndex: 1) or hardcoding a tab-index array. Must not depend on an unasserted tab.Container internal without noting it.
• Patch Verdict: Matches. routes config → per-route handler → activateRoute finds the tab by button.route and sets activeIndex = tab.index. Verified the real propagation: getTabButtonConfig returns {...defaultConfig, ...config} (spreads item.header) and sets index, so header.route + index carry to the HeaderButton; reference: 'shell' exists (Viewport:73); unknown route no-ops safely. Default mount unchanged.
• Premise Coherence: Coheres — additive route layer over the shipped shell; no boundary violation, no regression to the #14847 default-Fleet mount.

🔬 Depth Floor

Challenge (non-blocking): the activation rests on an implicit tab.Container contract — that getTabButtonConfig spreads header.route onto the button and sets index. I verified it holds today (Container.mjs:429 + :418). But the spec is mock-only: createController() hand-builds a fake shell whose tab buttons already carry .route/.index, so it never exercises the real header→button generation. If a future refactor makes getTabButtonConfig cherry-pick header props instead of spreading, every route breaks silently and these tests stay green (the ?./find swallow the miss). Suggest one real-integration assertion (instantiate the real Viewport, assert its tab buttons expose .route) or the NL deep-link e2e (navigate #/fleet → Fleet activates) to lock the contract. Also minor: a tab click now sets activeIndex twice (the header domListener + the route round-trip) — harmless/idempotent, and it's what gives the shareable URL, so not a defect.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: tab.Container propagates arbitrary header.* configs onto the tab HeaderButton via {...defaultConfig, ...header} — the idiomatic way to attach route (and other button configs) per keeper-view. Reviewers can rely on the spread, but a consumer leaning on it should assert it (mock-only coverage hides a future spread→cherry-pick regression).
• [TOOLING_GAP]: Could not run the spec locally — this clone's unit runner hangs on the Chroma webServer gate; scored from static read + verified source + green CI.

N/A Audits — 📑 🪜 📡

N/A across listed dimensions: no external contract ledger surface, no host-unreachable runtime AC beyond the noted NL suggestion, no OpenAPI touch.

🎯 Close-Target Audit

• Close-target: Resolves #14632.
• #14632 is a leaf (enhancement), not epic-labeled. Pass.

🔗 Cross-Skill Integration Audit

• Adds a routes convention to the agentos shell controller; self-contained (Neo router → controller routes is an existing framework primitive, no new cross-skill surface). No integration gap.

🧪 Test-Execution & Location Audit

• Local spec run: No — clone Chroma-webServer runner hang; relied on static read + verified source + green CI.
• Canonical location: test/playwright/unit/apps/agentos/ViewportController.spec.mjs — correct.
• Coverage present (routes-declared, per-route activation, unknown-route no-op, config-alignment) — but mock-only on the activation path (see Depth Floor).

Findings: Location ✓; execution deferred to CI; recommend a real-integration/NL assertion for the header→button propagation.

📋 Required Actions

No required actions — eligible for human merge.

Optional (non-blocking): one real-integration or NL assertion locking the header.route → tab button propagation, so a future getTabButtonConfig change can't break routes with green tests.

📊 Evaluation Metrics

Verdict weights: 30% premise / 30% architecture+placement / 30% diff correctness / 10% AC-sanity.

• [ARCH_ALIGNMENT]: 90 — routes map + handlers in the right home; leverages tab.Container's header-spread idiomatically; default mount preserved. −10: 5 near-identical onXRoute handlers delegating to activateRoute could be one data-driven binding.
• [CONTENT_COMPLETENESS]: 85 — clean JSDoc + a config-alignment guard. −15: the spec mocks the shell, so the real header→button route propagation the feature rests on is unasserted.
• [EXECUTION_QUALITY]: 84 — logic verified correct against the real source (spread + index carry; reference:'shell' present; safe unknown-route no-op). −16: not locally executed (clone runner hang); mock-only activation coverage.
• [PRODUCTIVITY]: 90 — delivers #14632's route/deep-link residual; tab-click now updates the URL.
• [IMPACT]: 55 — route/deep-link layer over the already-mounted cockpit; useful, not gate-defining.
• [COMPLEXITY]: 35 — one controller config block + thin handlers + per-header props; low reader load.
• [EFFORT_PROFILE]: Quick Win — small, high-clarity route layer.
