The /health endpoint was the only W-026 API route with no UI consumer.
Surface it as a liveness indicator (colored dot + label) in the status
footer, isolated from /runtime/status so a live server still reads
"Healthy" even when runtime status is degraded.
- types: HealthStatus matching the server's {"status":"ok"} payload
- client: fetchHealth() with a short 3s timeout for fast failure
- queries: useHealth() polling every 15s, retry disabled
- footer: HealthIndicator rendered in both normal and degraded branches;
any non-ok status fails safe to "Unhealthy"
- tests: healthy / errored / non-ok / checking / survives-runtime-failure
Two UX wrinkles surfaced while exercising the CORE-Logos Studio:
- DAG viewport: tall, few-layer graphs (e.g. the 408x1890, 2-layer/55-node
alignment fan) were squished by viewBox-meet into an unreadable sliver. Render
at natural height (scale ~1) inside a bounded, scrollable box; small graphs are
unaffected (>= the caller height). Golden layout unchanged (layoutDag untouched).
- Click-to-copy: new shared useCopyToClipboard hook gives every copy affordance a
tooltip + transient confirmation. StatusFooter SHA now confirms 'Copied' (was a
silent copy that read as 'does nothing'); 'Read Only' is labeled a non-interactive
status (not a toggle); checkpoint-revision gains an explanatory tooltip.
DigestBadge + MetadataTable copy buttons route through the hook + gain titles.
Full workbench-ui vitest: 520 passed (+4), clean exit; tsc + build clean.
Lands the Phase C "make cognition legible" slice plus Phase A residue, all
backend-reader-first over real engine data (no theater, read-only doctrine
intact, zero serving-path imports).
C1-a — Cognitive pipeline record (persistence-first, per #729 worthiness edit):
- workbench/pipeline_record.py: curated CognitivePipelineRecord over the real
CognitiveTurnResult (input → intent → proposition_graph → articulation_target
→ realizer → walk_telemetry → trace_hash). Raw field multivectors are
DELIBERATELY excluded; _assert_no_raw_field_payload recursively rejects raw
field keys, and validate_pipeline_record fails closed on missing/duplicate
stages, non-recorded status, or dangling edges — the UI can never receive a
partial record that claims to be complete.
- test_workbench_pipeline_record.py: non-vacuous guards — missing stage,
monkeypatched new required stage, and injected raw {"F": [...]} each raise.
C2-a — Contemplation as a process: /contemplation route over real persisted
contemplation/runs/*.json (glob reader; honest-empty when absent).
C4-a — Identity continuity (L10/L11): RunDetail.identity_continuity + Runs
Identity tab, sourced from the real core.engine_identity (engine_identity /
parent_engine_identity lineage relation, re-derived to verify).
Demo Theater: renders backend-owned proof-promotion + entailment DAGs.
Phase A residue: density preference wired end-to-end (settings → shell → tokens);
cross-route consistency touch-ups.
Infra: local API CORS now echoes only validated 127.0.0.1/localhost origins
(hostname-checked, not arbitrary reflection) so Vite fallback ports work.
Route chunk-split keeps the build warning-free.
Cleanup: corrected the stale ADR-0175 practice-lane assertions (build_report is
6 correct / 0 wrong / 44 refused after the current serving lane; wrong=0 held)
and the two registry-derived count tests (LeftNav + CommandPalette 12 → 13 for
the new Contemplation route).
Docs: runtime_contracts.md (pipeline-record contract), UI-UX-GUIDE,
api-contract-v1, data-shapes-v1, wave-M-worthiness, phase-a-residue-ledger.
Validation: 106 workbench/practice Python tests green (incl. wrong=0 lane +
pipeline-record fail-closed guards); 459/459 frontend; pnpm build clean;
git diff --check clean. No generate.derivation / reliability_gate / stream /
field.propagate / vault.store imports.
