Summary

What lands

Browser-only, no BFF change: the search index (a pure function over already-served inventories plus the static pages), the palette in the top nav with its keycap, the shortcuts reference page over the closed registry with help-feature rows read off the same capability gates the owning components use, /workspace/shortcuts, and the about section's "Keyboard shortcuts" link.

Verification

89 server and 236 web Vitest proofs (8 ACs, 0 missing); task studio:check, task docs pass; apps/contracts unchanged.

Further amendments

Implements the amended search contract (see the plan layer below):

• The palette runs on the Radix dialog and uses a modal shortcut scope in the provider. Its input and results follow the combobox/listbox pattern, and the highlighted result scrolls into view.

• IME composition is ignored.

• Schedule prompts are no longer indexed.

• The Memory row on the shortcuts page follows the user-model capability.

• Exact matching. The shortcut matcher now requires exact modifiers. A registry-wide table test checks each binding matches exactly its documented combination.

• Plan status. This layer's diff moves its acceptance plan to landed (header and index), per the plan lifecycle; the transition is authoritative only when this PR merges, and task ac-trace-strict now gates the plan.

Re-verified on the rebased stack: task studio:check passes (128 server + 295 web Vitest), and task ac-trace-strict passes with every Studio plan gated as landed (141 ACs, 0 failures).

Development stage

• Plan / Interface
• Implementation
• Combined
• Spike / Routine / Cleanup

Contract linkage

• Work classification: Bounded
• Classification rationale: two browser-only surfaces over inventories the BFF already serves; no BFF route, schema, or daemon change
• Decision record: None — see the plan layer
• Human waiver of spine: Yes — the directing human chose stacked (gh stack) delivery for the whole Studio series: nothing merges until every layer is reviewed, so the plan's approval-by-merge event is deferred to the end (recorded in each plan's Delivery line), and each implementation layer records the exact plan commit it built against.
• Acceptance plan: docs/acceptance/studio-search-shortcuts.md
• Human decisions resolved and recorded: Yes
• Plan / Interface PR: docs(plan): Mecatl Studio global search and keyboard shortcuts acceptance plan #1763
• Approved commit baseline: 3412b3b6f32611ab6f347e4d384a6ac22c7a8bbc (the plan layer below; not yet merged — stacking exception above)
• Combined/exemption rationale: N/A

Interface conformance

• Matches the plan's contract.

Issue relationship

Relates to #1751 (parent #1736; stack #1766). Non-closing: the step completes when both of its layers merge.

Type of change

• Behavioral/interface plan
• Bug fix
• New feature
• Refactoring (no behavior change)
• Dependency update
• Documentation/process

Test plan

Baseline checks

• Acceptance-plan checker
• Linting (task lint)
• Offline test suite (task test)
• Offline demo (go run ./cmd/mecademo)
• Markdown changed: docs generation/link checks (task docs)

Studio gates (this workspace is not covered by task lint / task test, which are Go-only): task studio:check (Biome, typecheck, Vitest, generated-drift), task ac-trace — all pass; see Verification above.

User-facing change

Studio gains a global search palette and a keyboard-shortcuts reference page.

Special notes for reviewers

Part of a fourteen-layer stack; review bottom-up. Nothing merges until the whole series is reviewed.
