Canonical selected-part guidance vertical

#1150 owns one coherent selected-part rehearsal-guidance vertical instead of three overlapping Workspace/locales/docs writers. It preserves the original entrance cue and has absorbed the complete valid deltas from closed successors #1151 (first-pass take) and #1157 (room-confirmed chord). Their checks/reviews/approvals/statuses do not transfer.

Fresh exact identity

  • protected target: develop@889d782e88b4df28dcbb4ae3cfd6d99ef85d9844
  • branch: feat/workspace-selected-part-entrance-cue
  • exact head: 1f786757abdf34c44ed8585f20ce1c994e849ed0
  • restack: non-force merge descendant of the protected target; the only intervening protected delta was Tauri Cargo.lock, adopted as the exact protected blob. develop -> #1150 remains the same 23-file selected-part semantic delta with no lockfile change.

Buyer behavior retained together

After a named part is selected, the ready rehearsal workspace can now show, from admitted project evidence:

  • the first trusted lyric/count/transition cue to catch before entrance;
  • the first trusted simplification to play before adding the rest;
  • the first trusted user harmony override to lock before the section.

Missing or untrusted entrance/first-pass evidence produces an explicit confirmation action; confirmed-chord guidance stays hidden when no trusted user harmony override exists. These are rehearsal guidance only and do not replace Active Player #961 or MIR #770/#828.

Trust boundary

  • own-property runtime admission for role/section/cue/simplification/manual-override evidence;
  • shared SECTION_FORM_LABELS is the section-label authority;
  • duplicate/conflicting selected-role identities fail closed;
  • only user-origin harmony overrides become confirmed-chord authority;
  • sparse/malformed collections and getter/prototype traps fail closed where applicable;
  • placeholder interpolation never grants inherited object members authority.

Verified succession

#1151's unique first-pass implementation, domain tests, mounted Workspace test, and doctoring note are byte-identical Git blobs on this branch. #1157's confirmed-chord domain/mount tests and doctoring note are likewise byte-identical; its selector was intentionally strengthened to consume shared SECTION_FORM_LABELS instead of a duplicated local label set. Shared Workspace, locale, architecture/changelog/agent docs, and component contracts are integrated as one union rather than copied as conflicting siblings.

UI evidence boundary

Repository component contracts currently identify Figma file zthWmqfNKUgJBECvv002Qk, but the three selected-part nodes are explicitly marked pending live Figma node verification. The prior reused 19-239 claim was removed rather than fabricated. Shipped Tauri/current-head interaction evidence remains the final acceptance target.

Merge gate

The new exact head must reacquire every applicable required repository/central check in terminal success, zero valid unresolved findings, and a qualifying independent non-author last-push approval under live default-branch protection. Pre-restack checks/reviews/approvals do not transfer. Queued/pending/skipped-required/cancelled/failed/neutral/stale/predecessor/protected-base/model-only/self/author/admin-bypass evidence is non-passing. Do not churn the head merely to retrigger checks; repair a real defect or rerun eligible failed infrastructure work in place.

Relates to #966, #961, #770.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 1f786

Selected-part confirmed-chord guidance can make the workspace fail to render when malformed override data throws during processing. Contain those failures and return unavailable guidance before merging.

🔍 Figma contracts remain unverified

The three callouts lack matching Figma nodes despite the review rule requiring them. The catalog cannot map these patterns to its authoritative design source.

Finding remains valid on exact head 1f786757abdf34c44ed8585f20ce1c994e849ed0. I attempted live lookup of Figma file zthWmqfNKUgJBECvv002Qk; both file metadata access and account identity resolution require interactive Figma authorization/input in this non-interactive owner run, so no node ID can be truthfully asserted. I converted #1150 back to Draft and am leaving this thread unresolved. GREEN requires live verification of the three selected-part callout nodes (or an explicit product/design decision to create them), then recording the exact node IDs in docs/design-system/component-contract.md and validating the mapped UI states/interactions. Reusing an unrelated historical node or inventing an ID is non-passing.

Noema LLM review

The selected-part guidance vertical is complete and well-tested. firstEntranceCue, firstPassSimplification, and selectedPartConfirmedChord all fail closed on malformed shapes, inherited members, duplicate ids, conflicting display names, non-canonical labels, and missing/blank values. Workspace now mounts the entrance-cue, first-pass, and confirmed-chord callouts, and RoleSwitcher clears a stale activeRole when a project no longer contains it. The test suites duplicate the runtime validation invariants and cover both English and Korean copy paths. No blocking correctness, security, or regression issue was confirmed against the current head.

Reviewed changed lines

  • apps/desktop/src/features/workspace/RoleSwitcher.tsx:44 (RIGHT): The useEffect clears activeRole only when it is non-null and absent from the current role allowlist, fixing the previously reported stale entrance card after project change.
  • apps/desktop/src/features/workspace/firstEntranceCue.ts:104 (RIGHT): Runtime validation requires own id/name properties, rejects duplicate ids and inherited cue members, and fails closed before any malformed role can reach a user-visible entrance cue.
  • apps/desktop/src/features/workspace/firstEntranceCue.ts:162 (RIGHT): The function iterates sections in array order and returns the first ready canonical cue. This preserves the documented timeline contract without sorting by timeRange.start.
  • apps/desktop/src/features/workspace/Workspace.tsx:436 (RIGHT): The entrance-cue callout renders only inside the selected-part region and uses the t(...) copy for both ready and unavailable states, so guidance is never shown before a named part is selected.

Adversarial validation

  • apps/desktop/src/features/workspace/Workspace.tsx:595 (RIGHT) falsified: The missing trailing newline at the end of Workspace.tsx will break formatting or CI. — A missing trailing newline does not change behavior, and no repository rule or changed-file evidence in the diff establishes a required CI gate for newline termination. The claim is stylistic and was not confirmed as a blocking failure.
  • apps/desktop/src/features/workspace/Workspace.confirmed-chord.test.tsx:44 (RIGHT) falsified: The Korean confirmed-chord copy is ungrammatical because the locale key still places a particle directly after {chord}. — The asserted Korean expectation is '...확인한 C#m11 코드로 맞춥니다...', i.e., the particle-safe phrasing the prior thread recommended. The changed-file context does not contain the locale value that would reproduce an ungrammatical string, so the mismatch could not be confirmed at head.
  • Residual risk: Low. The locale JSON was not part of the truncated diff, so the Korean confirmed-chord translation itself was not directly inspected. The workspace-level Korean test asserts the expected particle-safe string, and the outdated locale thread was superseded by a test that encodes the corrected copy; no reproduced failure was found.

Findings

Adopt develop's exact Tauri lockfile artifact while preserving the canonical selected-part rehearsal-guidance semantic delta. No force-push or history rewrite.
