First R3 (Theater) piece. Reworks the stale artifact-keyed ReplayRoute into
the turn-keyed hero over the #716 sealed-replay backend, and fully retires
the dead W-026 artifact-keyed machinery on both sides (the NOT_YET_MIRRORED
comment anticipated this).
The hero makes determinism *felt*: pick a journaled turn, CORE re-executes
its prompt in a sealed fresh runtime, and the result renders as a hash
verdict (≡ equivalent / ≠ diverged) + the original/replay DigestBadges + a
leaf diff (critical weighted above informational, each with a ≠ glyph). The
'What this proves' card surfaces comparison_basis + origin_state and states
the honest limit: a divergence means nondeterminism OR origin-state
influence, never rendered on its own as a determinism failure.
Retirement (verified zero serving uses):
- Python schemas.py: removed ReplayComparison/ReplayDivergence/ReplayStatus/
ReplayDivergenceSeverity; scripts/dump-enums.py drops the two replay enums;
both snapshots regenerated (deterministic: dump == committed)
- TS: removed ReplayComparison/ReplayDivergence/ReplayDivergenceSeverity;
added TurnReplayComparison/TurnReplayDivergence (+ basis/origin/severity
unions); NOT_YET_MIRRORED now empty (every engine schema mirrored)
- badges: removed ReplayStatusBadge + ReplayDivergenceSeverityBadge +
meta/enums + their enumCoverage cases (hero renders severity inline)
- api: fetchReplayComparison/useReplayComparison -> fetchTurnReplay/
useTurnReplay (/replay/<turnId>)
- deleted ArtifactList, ReplayComparisonPanel, ReplayDiffViewer,
ReplayMetadataTable, old replay.test.tsx
- App route /replay/:artifactId? -> /replay/:turnId?; conformance row
turn-keyed (loading 'Loading turns...', empty 'No turns recorded yet.')
Tests: ReplayRoute.test.tsx (equivalence hero + honesty card, diverged
critical leaf, informational-only label, replace-mode select, j/k spine).
Full vitest 358 green; workbench Python 34 green; both snapshots deterministic.
Follow-up flagged (not in this PR to keep it focused): the artifact query
hooks (useArtifacts/useArtifactDetail/fetchArtifacts*) are now orphaned but
entangled with the still-live artifact EvidenceSubject kind — a separate
cleanup once an Artifacts route or that subject's fate is decided.
Brief: docs/handoff/wave-R3-briefs-2026-06-13.md (all four R3 pieces).
Replaces VaultRoutePlaceholder with the real route over the R2-B
/vault read substrate (#712).
- TS mirrors VaultSummary/VaultEntry; both removed from NOT_YET_MIRRORED.
Also fixes a latent ErrorCode drift: adds 'evidence_unavailable' to the
TS union (present in Python schemas, missing in TS) — the route branches
on it.
- fail-closed is the design: a missing/unpersisted vault (the 501
evidence_unavailable signal, or persisted=false / entry_count=0) renders
the honest absence card as the PRIMARY state, naming the opt-in
RuntimeConfig.persist_session_state pointer — not a generic error, no
skeleton theater
- with data: summary strip (entry_count, store_count, reproject_interval,
max_entries, source_path) + VirtualizedList of entries with
epistemic_status / epistemic_state pills and versor_digest DigestBadge
- exact-recall doctrine: renders only backend fields; never computes or
displays a similarity/relevance proxy (runtime recall is exact cga_inner)
- selection publishes the vault_entry subject (inspect-param only, via
setSubject + setInspectorOpen; EvidenceUrlSync writes ?inspect=vault:N);
a URL-restored identity-only subject is hydrated once entries load
- Vault row added to routeConformance MOUNT_ROUTES — the fail-closed
absence asserted as the primary contract
- tests: fail-closed card (not error), summary+entries, no-similarity-score
doctrine, vault_entry subject publication, j/k spine
Token-only styling (hexScan green).
Replaces PacksRoutePlaceholder with the real triad route over the R2-B
/packs read substrate (#712).
- TS mirrors PackSource/PackSummary/PackDetail; PackSummary/PackDetail
removed from NOT_YET_MIRRORED (drift gate now enforces them)
- new design primitive TreeView (src/design/components/TreeView): a
deterministic, keyboard-driven JSON tree — object keys sorted, array
indices in order, no animation; ←/→ collapse/expand, ↑/↓ + j/k move,
Home/End jump, Enter toggles; registers its shortcuts only while focused
(KeyboardHelp never advertises tree controls when no tree is on screen)
- list pane: VirtualizedList + useListNavigation (j/k) + SearchInput; rows
show pack_id, source, version, language/modality, determinism_class pill
- detail pane: Panel + TabBar (Manifest / Checksums / Raw); Manifest renders
via TreeView; Checksums is the verify affordance — manifest_digest and
declared checksum as DigestBadges plus the per-field manifest checksums
table (the checksum-hashes-the-bytes-on-disk doctrine made visible); Raw
collapsed by default
- selection publishes the pack subject (R2-S), records /packs/<packId>
(replace), pushRecentItem on visit
- Packs row added to routeConformance MOUNT_ROUTES (loading 'Loading
packs...', error 'No packs mutation occurred.', empty 'No packs
discovered.' + core pack validate <path>)
- tests: TreeView (sorted/collapsed/expand/collapse/focus/click/empty) +
PacksRoute (list, replace-mode select + manifest tree, checksum verify
affordance, j/k spine)
Token-only styling (hexScan green).
Replaces the RunsRoutePlaceholder with the real triad route over the
R2-B /runs read substrate (#712).
- TS mirrors RunSource/RunSummary/RunTurnRef/RunDetail; all three classes
removed from NOT_YET_MIRRORED (drift gate now enforces them)
- list pane: VirtualizedList + useListNavigation (j/k) + SearchInput;
rows show source, session_id, turn_count, relative timestamp, a
checkpoint badge (present + revision vs 'no checkpoint'), and any
evidence_gap rendered honestly in-row (never hidden)
- detail pane: Panel + TabBar (Turns / Manifest / Raw); every turn row
is an anchor to /trace/<turn_id> (backend-provided trace_path) with the
trace_hash as a DigestBadge — the cross-link is the point of this route;
turn list pages via turn_limit ('Load more turns')
- selection publishes the run subject (R2-S) and records /runs/<sessionId>
in the URL (replace), pushRecentItem on visit
- Runs row added to routeConformance MOUNT_ROUTES (loading 'Loading
runs...', error 'No runs mutation occurred.', empty 'No runs recorded
yet.' + core chat)
- RunsRoute.test.tsx: list evidence, in-row gap, replace-mode URL select,
trace cross-link hrefs, manifest tab, j/k keyboard spine
Token-only styling (hexScan green); full vitest 339 green.
