Capability Interaction Map — Scenario Explorer and Screenshot Acceptance Spec

Status: approved UX contract for 7F implementation (TASK-16899, 2026-08-09). Owner: UXDesigner. Implementer: 7F (browser scenario explorer), integrating 7C mock adapter output and 7E parity output. Companion records: Capability contract, spec/capability/eval-traceability.yaml, the Capability plan (TASK-16897), Live console interaction map, SDK component decisions. (annotated desktop + mobile renders in .paperclip-local/evidence/capability/).

This map is the interaction contract for the Capability browser scenario explorer. The explorer is a read surface over records the runtime already produced. It renders scenario metadata from the generated 7A traceability manifest, run artifacts from the 7C mock control-plane adapter, and parity results from the 7E conformance suite. The UI never owns state, policy, credentials, or execution decisions: it does not compute tool exposure, does not evaluate claims, does not apply redaction, and holds no Paperclip or provider credential. Every allow/deny, redaction, and state transition shown on screen must arrive as a record emitted by the mock core.

0. Naming, vocabulary, and canonical labels

• Product name in the UI: Scenario Explorer (header: “Capability scenario explorer — mock control plane”).
• UI copy uses the canonical term task (DESIGN.md principle 7). Eval case IDs, fixture IDs, route paths, JSON payloads, and source anchors are machine values and stay verbatim (issues, i-0102, MCK-102) in monospace — never “translated.”
• The three dispositions render with exactly these labels, everywhere: Control plane (control_plane_owned), Always tool (always_agent_tool), Optional tool (optional_agent_tool). The traceability panel and all badges must use the 7A contract values as their source; no UI-local re-classification.
• The five assertion classes render as: Invariant (control_plane_invariant), Tool contract (agent_tool_contract), Authorization (authorization_policy), Multi-hop (combined_multi_hop), Restraint (restraint_no_call).
• Parity statuses: Pass, Fail, Intentional gap, Not run. Each has an icon + text label; color alone never encodes status (WCAG color-independence).

1. Shell and information architecture

Package-local Vite entry examples/scenario-explorer/ with script demo:scenarios (default port 4183; 4182 belongs to the Standalone demo). It runs from static assets plus checked-in fixtures with no Paperclip services and no network dependency in fake-agent mode. Reuse the frozen 0.1.2 SDK surface (@paperclipai/paperclip-runner/react + ./styles.css) through its five approved extension points; do not fork the token layer.

Desktop layout (≥ 64rem), one React tree (SDK finding — never render two trees):

• Left rail (--pcr-rail-width, 17rem): scenario picker — search, facet filters, case list grouped by eval group.
• Center column (fluid, max --pcr-center-width, 48rem): run view — the chronological scenario transcript and the run header (verdict banner, mode toggle, run/replay controls). Primary surface, strongest hierarchy.
• Right rail (--pcr-inspector-width, 24rem): inspector with four tabs — Context · Authorization · State diff · Parity. Open by default on desktop (unlike the 4b protocol inspector: here the inspector carries first-class acceptance evidence, not diagnostics).

Mobile (< 64rem): single column behind a segmented control (Scenarios · Run · Inspect), same pattern as the Live console console. The segmented control is sticky at the top; the Run segment is the default when a case is selected via route. Touch targets ≥ --pcr-touch-target (2.75rem).

Density: diagnostic-console dense, like 4b. All spacing, color, type, radius, motion from --pcr-* tokens only (DESIGN.md principles 2–4; pnpm check:token-gates applies).

2. Scenario picker and filters (left rail)

Source of truth: the generated scenario index derived from spec/capability/eval-traceability.yaml (all 106 cases, 16 groups) plus the latest parity results artifact from 7E. The picker consumes these; it never re-derives group membership or dispositions.

Contents, top to bottom:

1. Search input — substring match on case ID and title. Mono rendering of matched IDs. Debounce ≤ 150ms (Doherty).
2. Facet filters (collapsible group, --pcr-facet-height baseline):
   • Group — the 16 eval groups (hb 5 · co 6 · st 8 · cm 6 · se 4 · su 4 · bl 5 · dp 3 · ix 9 · ap 6 · ar 4 · er 9 · rf 22 · mh 4 · rs 3 · wk 8), each with its case count.
   • Case — direct case-ID picker (combobox) for jump-to-case.
   • Disposition — Control plane / Always tool / Optional tool, from primaryDisposition.
   • Role — actor role of the fixture (ic, manager, reviewer, board_user, …) from the scenario index (§9 data contract).
   • Claim — required grants from requiredGrants (e.g. approval:read), rendered mono.
   • Parity status — Pass / Fail / Intentional gap / Not run, from the parity artifact. Facets are AND-combined across facets, OR-combined within a facet. Every facet value shows its live result count; zero-count values stay visible but disabled (recognition over recall — the vocabulary stays learnable). An active-filter chip row with per-chip remove and one Clear filters affordance sits above the list (forgiveness).
3. Case list — grouped by eval group with sticky group headers. Each row: case ID (mono, --pcr-font-size-xs), title (one line, truncated with full text in a tooltip), disposition badge, parity status dot+icon. Selected row uses --pcr-accent-surface with a --pcr-accent left rule.

Keyboard: the list is a single-select listbox (role="listbox", aria-activedescendant); Up/Down move, type-ahead jumps, Enter selects and moves focus to the run header. Facets are disclosure buttons + checkbox groups. Filter state mirrors into the route (§7) so any filtered view is linkable; filter state is never stored as protocol state.

Empty results: “No scenarios match these filters.” + Clear filters button — never a bare void.

3. Run view (center column)

3.1 Run header

• Case ID (mono) + title, group badge, disposition badge, assertion-class badges.
• Verdict banner (SDK Banner): overall parity verdict for the last completed run — Pass (success surface), Fail (danger surface), Not run (muted). The banner names the assertion counts (“12 assertions · 12 pass”) and deep-links the Parity tab.
• Mode control: Fake agent (default) / Codex (bounded) segmented control. Fake mode is always available offline. Codex mode appears only when the local relay is reachable; otherwise the option renders disabled with the reason (“provider relay not running — see tutorial §4”). The browser never holds a provider credential; Codex traffic goes through the same server-side relay boundary proven in SDK.
• Run / Re-run button and replay controls (SDK replay-controls). Deterministic fixtures mean re-run in fake mode reproduces the identical timeline; state diffs and parity always describe the displayed run.

3.2 Scenario transcript

Source of truth: the ordered run artifact timeline emitted by the mock core (§9). Items render in artifact order; the UI never reorders, merges, or re-times entries.

The transcript interleaves two visually distinct channels (Similarity + Common Region — a stranger must tell them apart in two seconds):

1. Agent channel — model turns and semantic tool calls/results. Aligned with the standard conversation layout (SDK conversation/message/ tool-item). A semantic tool call renders collapsed by default with a one-line summary: operation ID (mono) + disposition badge + one-phrase outcome (“finish_task · Always tool · committed”). Expansion is the item-body / request-detail extension point (§8) and shows: operation ID and version, argument JSON, result JSON, idempotency behavior, claims the call required, and redaction chips (§5) — exactly the descriptor fields from the 7D catalog, never re-labeled.
2. Control-plane channel — actions the runtime performed with no tool (checkout, wake routing, budget stops, reconciliation, blocker wake scheduling…). These render full-width on a --pcr-muted surface with a “Control plane” badge and a gutter glyph distinct from tool items, and are indented from the agent lane. Copy states the actor plainly: “Control plane checked out task MCK-102 — no agent tool exists for this.” Each entry expands to the decision record (inputs considered, resulting state change, audit reference).

Failed/denied entries render in place on --pcr-danger-surface with the exact typed denial (§5) — failures are part of the record, never toast-only.

Restraint/no-call scenarios (rs-*, er-* restraint cases) must remain legible when the correct behavior is absence: after the final agent turn the transcript appends a system note “No further operations — N forbidden operations, none invoked” which deep-links the Parity tab’s forbidden list. Restraint evidence must never depend on an empty screen.

PRP events stay behind a per-item “Protocol events” disclosure (same nested pattern as SDK debugEvents) — the semantic view is primary; raw protocol stays inspectable but secondary (progressive disclosure).

Auto-follow, jump-to-latest, streaming affordances, and reduced-motion rules are inherited verbatim from the Live console map §1 — do not redesign them.

4. Inspector tabs (right rail)

All four tabs are SDK Tabs; the active tab mirrors into the route (§7).

4.1 Context

Answers “who ran, under what authority, with which tools” before any transcript reading (mental model first):

• Actor block: actor role, task mode, fixture ID (mono), wake payload summary (reason + trigger), budget posture.
• Capability grants: the scenario’s requiredGrants plus every grant the fixture actually issued, rendered as mono chips.
• Tool exposure list — the acceptance-critical view. Three labeled sections, populated only from the mock core’s exposure record:
  1. Always tools (N) — always-catalog operations visible this run;
  2. Optional tools (N) — visible optional operations, each with the grant that unlocked it (“decide_approval — via approval:decide”);
  3. Control plane — no tool (N) — control-plane-owned capabilities relevant to this scenario, explicitly listed so reviewers can verify absence (negative evidence must be visible, not implied).
• Traceability panel: source anchor (file:line, mono), skill elements (file · section · lines), evidence IDs, legacy MCP mapping row if any — verbatim from the 7A contract.

4.2 Authorization

Chronological table of every authorization record the mock core emitted: operation (mono), claims considered, decision (Allow / Deny with icon + text), reason string, redactions applied, resulting state change reference. Row expansion shows the full record JSON. Denied rows use --pcr-danger-surface; a count chip on the tab surfaces denials without opening it (“Authorization · 1 deny”). Selecting a row scrolls/flashes the corresponding transcript entry (uniform connectedness across panels).

4.3 State diff

Before/after immutable snapshot diff for the displayed run, grouped by the ten entity domains in the plan: tasks, comments, documents, interactions, approvals, artifacts, blockers, workspace, budget, run. Each domain is a collapsible section headed by a change summary (“tasks · 1 changed”, “comments · 2 added”); unchanged domains collapse to a single muted row (“unchanged”) so change carries the visual weight (Von Restorff). Rows show entity ID (mono) + field-level changes as field: before → after, with added/removed/changed markers as icon + label, not color alone. The diff is computed by the runtime/test layer and delivered as data; the UI performs no diffing of its own. A “final state” toggle shows the complete after-snapshot JSON per domain behind a disclosure.

4.4 Parity

The eval acceptance surface:

• Verdict header repeating the banner verdict.
• Assertion list: one row per conformance assertion — assertion class badge, human-readable expectation, Pass/Fail, and on fail an expected vs observed block (mono, side-by-side at desktop, stacked at mobile).
• Forbidden operations: each forbiddenSemantics entry with “never invoked ✓” or the violating transcript reference.
• Intentional gaps: entries marked as intentional exclusions render under their own heading with the recorded rationale — visually distinct from Fail (a gap is a decision, not a defect).
• Legacy baseline note: the case’s skill-present/skill-absent reference note, verbatim, muted — labeled “reference baseline, not the pass condition.”

5. Credentials, redaction, and denial rendering

• Fake mode performs zero network I/O; Codex mode talks only to the local relay; no route, storage key, or bundle string may contain a Paperclip or provider credential. localStorage may hold UI preferences only (inspector tab, filter collapse state) — never run artifacts, grants, or anything from a fixture.
• Redacted values arrive pre-redacted from the mock core. The UI renders a redaction chip: ••• + “redacted” label + the redaction-rule name in a tooltip. The UI must not receive-and-hide secrets; if a raw secret ever reaches the browser payload, that is a 7C/7D defect, and the explorer additionally fails closed by rendering nothing for fields flagged redacted.
• A denied tool call renders the typed policy denial: operation, the missing claim, and the denial reason — and never any protected state. An absent tool simply does not appear in exposure lists; the Context tab’s control-plane section is the affordance proving absence is intentional.
• The generic escape hatch (paperclipApiRequest successor), when a test scenario grants it, renders with a persistent --pcr-warning-surface “test-only escape hatch” banner on every call card (plan §4: visually flagged).

6. Accessibility, responsive, empty/error states

Accessibility (WCAG POUR; inherits all Live console/5 baseline rules):

• Landmarks: nav (picker), main (run view), complementary (inspector); one h1; group headers are h2/h3 in order.
• Full keyboard operation: picker listbox (§2); F6/documented shortcut cycles the three regions; tabs follow the WAI-ARIA tabs pattern (arrow-key activation); every disclosure is a real button. Visible focus ring via --pcr-ring everywhere.
• Live regions: run progress announces via aria-live="polite" (“Scenario run settled — verdict pass”); denial entries announce assertively once.
• Reduced motion: with prefers-reduced-motion, streaming reveal, banner transitions, and scroll-flash connect cues render instantly/statically (SDK rule).
• Contrast from the existing token pairs only; parity/authorization statuses always icon + text.

Responsive: content-driven single breakpoint at 64rem (§1). At mobile the inspector tabs become full-width stacked sections inside the Inspect segment; expected-vs-observed blocks stack; the transcript keeps every descendant intrinsically shrinkable (min-w-0 discipline) so no horizontal scrollbar appears at 390px (SDK finding).

States that must be designed, not defaulted:

State	Surface	Rendering
No scenario selected	Center + inspector	Explorer intro card: corpus stats (106 cases · 16 groups), “Pick a scenario” pointer at the rail, three example deep links. No dead panels.
Scenario selected, not run	Run view	Header + context render from the index; transcript area shows a primed empty state (“Run to produce the deterministic timeline”) with the Run button duplicated inline (Fitts). Diff/Parity tabs show “No run yet.”
Run in progress	All	Progress in the header (indeterminate, reduced-motion safe); transcript streams; tabs show live counts; controls disable with reasons.
Run failed (harness error)	Run view	Danger banner with the exact diagnostic + “Re-run”; partial timeline stays visible and labeled partial. Never silently reset.
Parity fail	Banner/Parity	Fail is a first-class rendered state (danger banner + failing assertion rows) — the explorer’s job is showing it, not avoiding it.
Denied/absent tool	Transcript/Context	Per §5.
Missing/invalid fixture or artifact	Shell	Error card naming the artifact path and the regenerate command (pnpm generate:capability-inventory / 7E command). No blank screen.
Codex relay unavailable	Mode control	Disabled option + reason; fake mode remains fully usable.

7. Deterministic screenshot routes

Hash routing (static hosting, no server rewrites):

#/                                  explorer home (picker + intro)
#/case/<case-id>                    scenario selected, not run
#/case/<case-id>?run=fake           deterministic fake run, auto-executed
#/case/<case-id>?run=fake&view=<transcript|context|authorization|diff|parity>
#/?group=<g>&disposition=<d>&role=<r>&claim=<c>&parity=<p>&q=<text>   filtered picker

Determinism contract for screenshot/CI use:

• run=fake auto-runs the scenario to completion on load; when the run and all panels are settled the shell sets data-run-state="settled" (Playwright wait target). Until then it is pending.
• Fake runs render fixture time only — no wall-clock timestamps, durations, or locale-dependent formatting anywhere in fake mode; ordering is by artifact sequence. Two loads of the same route are pixel-identical at the same viewport (modulo font rasterization).
• view= selects the inspector tab (desktop) or segment+tab (mobile); view=transcript closes nothing — it just guarantees focus/scroll starts at the transcript top.
• Stable data-testids (minimum set): scenario-picker, facet-<name>, case-row-<id>, run-header, verdict-banner, mode-toggle, transcript, transcript-item-<seq>, cp-action-<seq>, inspector-tab-<name>, exposure-always, exposure-optional, exposure-control-plane, authorization-row-<seq>, diff-domain-<name>, parity-assertion-<n>, redaction-chip.

8. Package-local implementation guidance (7F)

• Reuse first. Shell, transcript, and inspector compose the frozen SDK: RunnerConsoleApp is not the shell (this is not a chat console); compose conversation, message, tool-item, tabs, card, badge, banner, menu, dialog, tooltip, replay-controls from @paperclipai/paperclip-runner/react. Semantic call detail uses the item-body renderer (ext point 1); control-plane detail uses the request-detail renderer contract (ext point 2); theming via scoped --pcr-* overrides (ext point 4). Do not add SDK exports or break the 0.1.2 freeze — explorer-only components live in the explorer entry.
• New explorer-local components (system proposals, one job each): ScenarioPicker (search + facets + listbox), ExposureList, AuthorizationTable, StateDiff (domain sections + field rows), ParityPanel, RedactionChip, ChannelEntry (control-plane transcript entry). Each uses tokens only; any genuinely missing token (e.g. a --pcr-diff-* pair if muted/success/danger surfaces prove insufficient) is proposed in the 7F PR as a token addition, never inlined.
• Data contract consumed (owned by 7C/7E, not the UI):
  • Scenario index (generated from eval-traceability.yaml): id, title, group, fixture, actorRole, taskMode, primaryDisposition, requiredGrants[], assertionClasses[], sourceAnchor, skillElements[], evidenceIds[], forbiddenSemantics[]. If actorRole/taskMode are not yet in the manifest, 7C adds them to the index generator — the UI must not infer them from prose.
  • Run artifact (per scenario × mode): ordered timeline[] entries discriminated as semantic_call / semantic_result / control_plane_action / protocol_event_ref; exposure (always / optional-with-grant / control-plane lists); authorizationRecords[] (operation, claims considered, decision, reason, redactions, state-change ref); snapshots.before / snapshots.after per entity domain; parity (assertions with class/expected/observed/status, intentional gaps with rationale, legacy baseline note, verdict).
• Authority rule (binding): every rendered fact traces to one of those records. Grep-able heuristics, UI-side claim math, or re-deriving dispositions from case IDs are defects. If a view needs a fact the records lack, extend the record upstream.
• DESIGN.md alignment: tokens-only values; one component per job; hierarchy by structure not decoration (domain sections and channels use surface + position, minimal borders); status vocabulary systematic (§0 labels everywhere); machine values (IDs, anchors, grants, JSON) in --pcr-font-mono; canonical copy “task.”
• Testing hooks 7F must ship: component tests for the four inspector tabs and both transcript channels; keyboard-path tests (listbox, tabs, region cycle); reduced-motion test; the §7 route determinism test (two loads → identical settled DOM); accessibility assertions (landmarks, names, contrast tokens); screenshot capture script for §9.

9. Screenshot acceptance matrix

Evidence lands in .paperclip-local/evidence/capability/ as <slug>-<viewport>.png, at both 1440×900 and 390×844, captured from the §7 routes after data-run-state="settled". These twelve shots are the UX acceptance set for 7F (they also cover the plan’s human-checkpoint scenario families: heartbeat, planning, blockers, approvals, artifacts, interactions, manager, multi-hop, restraint).

#	Slug	Route	Expected visible evidence
1	explorer-home	#/	Picker with all 16 group facets and counts summing to 106; intro card with corpus stats; no dead panels.
2	picker-filtered	#/?group=ix&disposition=always_agent_tool&parity=pass	Active filter chips; filtered count visible; zero-count facet values disabled but legible; Clear filters affordance.
3	hb-heartbeat	#/case/hb-scoped-wake-01?run=fake&view=transcript	Control-plane channel entries for scoped-wake routing and checkout (“no agent tool exists for this”), then get_task_context agent call; pass banner.
4	wk-planning	#/case/wk-plan-directive-01?run=fake&view=transcript	write_document call with revision fields, revision-bound request_human_input (confirmation), review-parked disposition; no re-plan loop.
5	bl-blockers-diff	#/case/bl-create-blocked-01?run=fake&view=diff	State diff: tasks domain shows the new task created blocked; blockers domain shows first-class blockedByIssueIds; unchanged domains collapsed.
6	ap-approval-denied	#/case/ap-mcp-gate-01?run=fake&view=authorization	Authorization table with a Deny row (missing claim + reason, danger surface, no protected state); “Authorization · 1 deny” tab chip; transcript shows the typed denial card.
7	ar-artifacts	#/case/ar-upload-before-done-01?run=fake&view=transcript	register_deliverable completing before finish_task in artifact order; deliverable metadata in the expanded call card.
8	ix-interaction	#/case/ix-checkbox-01?run=fake&view=transcript	request_human_input(kind=checkbox) call card with options payload; control-plane wake/continuation entry; result inspection entry.
9	rf-manager	#/case/rf-api-mgr-heartbeat-01?run=fake&view=context	Context tab: manager role; optional discovery tools listed with their unlocking grants; control-plane “no tool” list populated; traceability panel showing source anchor + skill elements.
10	mh-multihop	#/case/mh-subtask-tree-01?run=fake&view=parity	Multi-hop assertion rows (child creation, chained blockers) all Pass; forbidden operations section showing “never invoked ✓”.
11	rs-restraint	#/case/rs-question-only-01?run=fake&view=parity	Restraint verdict: answer-only transcript with the “No further operations” note; parity forbidden list showing zero state writes; Pass banner.
12	rs-secret-redaction	#/case/rs-secret-hygiene-01?run=fake&view=transcript	Redaction chips (••• + rule name) in call/result cards; comment content free of the key; parity Pass.

Mobile captures use the same routes; the segmented control must show the correct active segment (Run for transcript shots, Inspect for tab shots) and no horizontal scrollbar may be present.

Acceptance procedure: UXDesigner reviews all 24 images against this matrix before 7F is accepted (plan §6: “UXDesigner supplies the interaction map and reviews screenshots before implementation acceptance”). Any deviation is either fixed or written into this document as a revision — silent divergence fails the gate.

10. Out of scope / rejected

• No second app shell, no Tailwind/Radix, no dark mode, no markdown renderer, no command palette, no transcript virtualization — SDK rejections stand.
• No editing affordances of any kind: fixtures, grants, and policies are changed in code/YAML, not in the browser. The mode toggle and run/replay controls are the only mutating-looking controls, and they mutate only the in-browser demo run.
• No parity “re-judging” in the UI: the Parity tab renders 7E output; it never recomputes assertions.
• No live-Paperclip or ACPX affordances; the future binding boundary stays a docs note, not a UI surface.

11. Revisions recorded during 7F implementation

Per §9, deviations are written here rather than left silent. All of the following were found while building the explorer (TASK-16904) and are now part of the contract.

1. Timeline entry kinds extended. §8 listed semantic_call, semantic_result, control_plane_action, and protocol_event_ref. The agent channel also needs plain model turns and the restraint note §3.2 requires, so the artifact adds agent_message and system_note. Protocol event references ride on semantic_result.protocolEventRefs rather than standing as their own entry, keeping the semantic view primary.

2. Parity is computed by the runtime, not the browser. §4.4 and §10 forbid the UI from judging assertions, and they do: the package-local scenario runner (src/scenarios/scenario-parity.ts) produces the verdict from the traceability expectations and the recorded artifact. The conformance suite's own per-case result is carried through verbatim in a separately labelled "Capability conformance suite" block and is never merged into, or used to overrule, the assertion list. When no conformance report is bundled the block reads Not run.

3. Actor role, task mode, and scenario claims are declared, not inferred. §8 assigned actorRole/taskMode to the scenario index generator; it shipped without them. They are now declared in src/scenarios/scenario-index.ts as an explicit fixture/case profile table, alongside the catalog claims each scenario grants. A claim that cannot unlock any operation in the scenario's task mode or for its actor role is dropped from the profile, so no scenario renders a grant chip that unlocks nothing.

4. The mobile section switcher is a radiogroup, not a tablist. §1 asked for the Live console segmented control. The Live console console renders it only in compact mode; the explorer keeps one CSS-driven tree, so a tablist would put two tablists in the document and model the three landmarks as tabpanels. The three regions stay nav/main/complementary, and the only tablist on the page is the inspector's.

5. Two token-layer overrides, scoped to the explorer. The SDK gives every direct span child of a disclosure summary min-width: 0; a Badge is also a span and sets white-space: nowrap, so at 390px badges were squeezed below their own content and pushed the page into horizontal scroll. The SDK badge also applies text-transform: capitalize, which renders "Optional Tool" and "Not Run" against the §0 vocabulary. Both are corrected in examples/scenario-explorer/src/explorer.css under .pcr7-shell; the frozen 0.1.2 sheet is unchanged. These are SDK defects worth fixing at the next SDK revision, not explorer quirks.

6. Only the case list scrolls in its own box. The rails are otherwise in page flow. §9 evidence is captured full-page, and an inner scroll container on the rail clipped exactly what the matrix asks to see (all 16 group facets and their counts). The 106-row case list keeps a bounded height so the page stays navigable.

7. Shot 2's route uses parity=not_run. §9 specified #/?group=ix&disposition=always_agent_tool&parity=pass. Parity status is a property of a run, and the picker route runs nothing, so parity=pass selects zero scenarios on a cold load. The recorded route filters on not_run, which is the honest cold-load state and still demonstrates chips, live counts, disabled zero-count values, and Clear filters.

The following revisions were recorded at the 7F UX gate (TASK-16905, 2026-08-09) after reviewing all 24 captures and a live keyboard/responsive session at both viewports.

8. Shot 8's continuation evidence is split across surfaces. In ix-checkbox-01 the continuation appears as the Context tab's control-plane exposure entry (route_wake — "Interaction continuations are routed by the control plane, not requested again") plus the parked-note system entry — not as transcript entries. No fixture in the corpus scripts the continuation-consuming side: only the ten §9 cases have bespoke fake-agent plans, ix-checkbox-result-01 falls back to a generic script that re-raises request_human_input (contradicting its own premise), and inspect_operation_result is catalogued but never invoked corpus-wide. Accepted for 7F because the request side and routing authority are fully evidenced; the continuation-side fixture upgrade is a filed follow-up, not a silent gap.

9. Forbidden-operations lists are empty corpus-wide. All 106 cases record empty forbiddenSemantics, so §9 rows 10–11's "never invoked ✓" rows cannot render from real fixture data. Restraint is proven by state-diff absence plus the intentional-gap rationale, and the Parity tab says so explicitly ("This case records no forbidden operations; restraint is proven by the absence of state writes in the diff"). The populated-list path (never invoked ✓ / violating transcript reference) exists in inspector-panels.tsx and is unit-tested; the explanatory empty state is accepted as the §9 rendering.

10. Keyboard deltas, accepted as interim with a filed follow-up. The picker listbox uses selection-follows-focus (arrows select immediately — a valid listbox pattern the map did not anticipate); type-ahead and Enter-moves-focus-to-run-header are not implemented; F6 region cycling is replaced by a "Skip to run view" skip link plus landmark navigation; denial entries do not announce assertively (only a fail verdict does). §7's inspector-tab-<name> testids are absent (the frozen SDK Tabs exposes roles, not testids) — tests target tabs by accessible name. An unknown case ID in the route falls back silently to the home view rather than a named error card.

11. Redaction chips render the rule name inline, not in a tooltip: ••• redacted <rule>. Inline beats hover-only disclosure (works on touch, visible in captures); recorded as the new §5 contract.

12. Evidence captures expand disclosures. The recorder opens every main/aside disclosure before capturing so argument payloads, decision records, and final-state JSON are visible in the §9 images. The live defaults are collapsed exactly as §4.3 specifies (verified in the gate's live session); the expanded captures are a deliberate evidence choice, not the default density.

13. UX-gate keyboard follow-up. The explorer handles F6 for region cycling when the browser delivers that key to the page. Chromium reserves bare F6 for browser chrome, so the documented in-page alternative is Control+Period; aria-keyshortcuts exposes both bindings. Either binding cycles picker (nav) → run (main) → inspector (complementary), with Shift+F6 cycling in reverse where bare F6 is available. The skip link remains unchanged.
