ui: align command-center shell with audience journey

[ndrorchestration]

Scope

Preserve the presentation-only audience-navigation/accessibility refinement stacked on #636. The intended journey remains Understand → Verify → Inspect → Operate, with Decision-Frontier-first control-room flow, runtime-observability disclaimers, keyboard/mobile navigation, focus restoration, skip link, and grouped hierarchy.

Current disposition — 2026-09-15

DRAFT / HOLD / STALE-LINEAGE / STACKED UNIQUE WORK. DO NOT MERGE AS-IS.

Current protected main is 1fb2c665587d5a0e7b213aef1cc5c870097cdc9b. Track A Epoch 002 collection is COMPLETE; operator retained-byte provenance is PENDING; dataset lock is NOT ESTABLISHED; unblinding and primary analysis are NOT AUTHORIZED; canonical efficacy is NOT_ESTABLISHED; High-Assurance remains PRE-FREEZE / FAIL-CLOSED / NOT AUTHORIZED / N=0.

This branch is stacked on stale #636 and inherits historical governance presentation. Its accessibility/navigation work remains potentially reusable, but it cannot be accepted independently or on historical validation.

Because the active #679 retained-byte checkpoint is bound to exact executing repository HEAD, do not reconcile this UI lane before that checkpoint. Avoid moving main solely to reduce UI backlog.

Future reconciliation

After #636 is reconstructed on a stable accepted frontier:

1. replay only the still-useful audience/accessibility delta onto that exact lineage;
2. remove inherited stale governance presentation;
3. preserve keyboard, mobile, focus, and semantic-navigation behavior;
4. require fresh exact-head UI/build/governance validation and applicable deployment success;
5. merge only from fresh evidence.

Governance boundary

No backend API, runtime telemetry authority, evidence class, empirical result, scientific N, efficacy, collection authority, dataset lock, unblinding, or analysis authority changes.

Current-state reconciliation — 2026-09-11

This stacked presentation lane is now behind accepted scientific state. Signed/verified main is 874945374dd4a00a56d6cb8d212c0aacd9ba6157 after #655, and Epoch 002 immutable freeze is ESTABLISHED.

Keep #649 DRAFT / HOLD. Its current presentation of immutable freeze as the next actionable transition is stale, and it remains dependent on #636. Do not merge it independently or advance main while active maintenance #657 and the immediate final-closure / verification-classification sequence are unresolved.

When the scientific sequence stabilizes, reconcile #636 first to the then-current accepted frontier, then reconcile/rebase #649 onto that accepted UI lineage and rerun fresh exact-head UI/GitHub/Vercel validation. No prior Vercel or GitHub evidence transfers after head changes.

Controlling posture: FREEZE ESTABLISHED · FAIL-CLOSED · SUCCESSOR COLLECTION NOT AUTHORIZED · N=0; canonical DGAF efficacy remains NOT_ESTABLISHED.
