Product outcome

The ready workspace already names tonight's first playable range. The cue sheet still dumped every section×role row first, so the download did not start with that same next action. The first-range card now names Download tonight's first-action sheet, and the CSV leads with that row when a concrete span can be matched.

Exact current identity

  • Protected target: develop@749511c3ad4000090048718f685c6bee6b3d2c25.
  • Exact current head: f1c22eacceb4a28ef26c0ac9ea411ae5cb6eb6b2.
  • Branch: feat/workspace-cuesheet-first-action.

Current exact scope

  • firstCueSheetLead matches firstRangeSqueeze to a concrete role on the untrusted song payload and fails closed when it cannot.
  • generateCueSheetCsv prepends an optional lead row; export.ts stays locale-free.
  • Formula-shaped harmony stays literal in the helper so escapeCsvField remains the only CSV-cell sanitizer.
  • Korean and English copy: workspaceFirstRangeDownloadSheet, workspaceCueSheetFirstActionSection.
  • Docs: AGENTS.md, CLAUDE.md, ARCHITECTURE.md, CHANGELOG.md, docs/architecture/overview.md, docs/doctoring/cuesheet-first-action.md.

Verification

  • Desktop vitest: export.test.ts, firstCueSheetLead.test.ts, Workspace.test.tsx, i18n/index.test.ts — 52 tests passed.
  • Desktop and shared-types tsc --noEmit passed.
  • Coverage include for src/lib/export.ts remains at the 90% gate.

Security Notes

Attack surface

Cue-sheet CSV is derived from untrusted analysis payloads. Section labels, groove, role names, harmony, cues, priorities, and notes can carry formula-shaped values (=, +, -, @) plus commas, quotes, and newlines.

Trust boundary

escapeCsvField is the only CSV-cell sanitizer. firstCueSheetLead treats the song as untrusted runtime data and fails closed. Lead-row values stay literal until that sanitizer runs. Filename sanitization for the download remains sanitizeFilename.

Mitigations

  • Prefix formula-leading cells with a single quote before structural quoting.
  • Do not invent a first-action row when the squeeze cannot be matched to a concrete role.
  • Keep formula-shaped harmony literal in the lead helper so escaping stays centralized in export.ts.
  • Do not weaken or duplicate the existing formula-injection tests.

Test points

  • apps/desktop/src/lib/export.test.ts proves a lead row is formula-escaped and that a missing/null lead does not add a row.
  • apps/desktop/src/features/workspace/firstCueSheetLead.test.ts proves fail-closed matching and literal formula-shaped harmony.
  • apps/desktop/src/features/workspace/Workspace.test.tsx proves the first-range card names the download and that the file starts with tonight's first action.

Realistic threats

Opening the CSV in a spreadsheet can execute formula injection from model-generated harmony, cue, or notes if escaping is skipped. A fabricated lead row would also teach the wrong first action.

Remaining risk

Spreadsheet software may still interpret escaped cells depending on locale and import settings. NUL-byte and other formula-injection bypasses stay fail-closed in escapeCsvField and are not suppressed here.

Dependency and Supply Chain

i18n impact

  • Korean and English locale impact was updated

Merge gate

Keep unmerged until this unchanged exact head has every applicable repository/central CI, coverage, SAST/security/SBOM/supply-chain gate terminal-success, zero valid unresolved findings, a qualifying independent non-author last-push approval, and ordinary branch-protection acceptance.

Queued, pending, skipped, cancelled, failed, predecessor-head, protected-base, model-only, self/author, or administrative-bypass evidence is not success.

Do not mix with #811, #828, #897, or first-X rehearsal-map PRs. #828 owns #770; do not open a parallel MIR PR. Do not self-approve.

Merge Risk: ⚪ Minimal · up to c9965

The PR makes the cue-sheet download lead with tonight’s first action while preserving validation and CSV escaping. A minor documentation identifier mismatch does not affect product behavior, so no actionable merge-blocking risk remains; merge is ready after normal checks, with that documentation correction as follow-up.

🟡 Stale role desynchronizes action card

When a replacement song lacks the selected role, currentSongRoleFilter clears it only for export. The firstRange card still reports no playable range.

@opencode-agent Become the sole writer for canonical BandScope branch feat/workspace-cuesheet-first-action only while it still resolves to exact head f177efac566b28e8edc4d73f02e476c5fcc1aac8 and protected develop still resolves to 749511c3ad4000090048718f685c6bee6b3d2c25. Apply superpowers:using-superpowers, receiving-code-review, systematic-debugging, test-driven-development, and verification-before-completion. Immediately before writing, refetch the exact branch/base, current Workspace.tsx, relevant Workspace.test.tsx/cue-sheet export tests, and unresolved thread PRRT_kwDORjvEXs6drW0g; abort/adapt if any owning blob or ref moved. Do not create a competing branch/PR, force-push, destructively rebase, weaken gates, or touch foreign repositories.

The current-head Devin finding is valid. Workspace retains activeRole across prop changes, recomputes roleMap for the new song, but handleExportCueSheet still passes the raw possibly-stale activeRole into firstCueSheetLead(song, activeRole, t). When the selected role does not exist in the replacement song, the otherwise-valid new song first action is omitted. activeRoleDetails already proves the safer current-song membership boundary through roleMap.get(activeRole).

TDD first: add the smallest realistic RED UI regression that renders a song, selects a role, rerenders the same Workspace instance with a different song whose current role map lacks that role but does have a valid first-action range, triggers Download tonight's first-action sheet, and proves the generated CSV starts with the replacement song's first-action row rather than dropping it. Preserve the current behavior when the selected role still exists in the replacement song. Prove the predecessor exact-head failure before source repair.

Then make the narrowest causal repair at the Workspace state/derivation boundary. Prefer deriving an effective current-song role (activeRole && roleMap.has(activeRole) ? activeRole : null) and use that consistently for buyer-visible per-role derivations that must not treat a stale ID as authority, including the cue-sheet lead. If changing all consumers would broaden scope, at minimum bind the export to the validated current-song role while leaving an explicit regression for the stale-prop transition. Do not hide the problem by weakening firstCueSheetLead fail-closed behavior.

Run focused Workspace/cue-sheet tests, desktop typecheck/lint/coverage-relevant tests, then repository quick/full applicable verification. Commit the RED regression plus causal repair to this same branch. Reply with predecessor RED evidence, successor exact SHA, focused/full GREEN evidence, and remaining exact-head gates. Do not resolve PRRT_kwDORjvEXs6drW0g until successor exact-head evidence proves it.

@opencode-agent Take the sole writer lease for one current-head BandScope-owned defect on canonical feat/workspace-cuesheet-first-action, and only if the branch still resolves to exact f177efac566b28e8edc4d73f02e476c5fcc1aac8 over protected develop@749511c3ad4000090048718f685c6bee6b3d2c25. Refetch head/base plus apps/desktop/src/features/workspace/Workspace.tsx and Workspace.test.tsx immediately before writing; abort/adapt if the lane moves. Use superpowers:using-superpowers, receiving-code-review, systematic-debugging, TDD for the behavior change, and verification-before-completion.

Fresh review finding discussion_r3893401014 is valid on this exact head: Workspace retains activeRole in component state across a song/project replacement, builds a new roleMap, but still passes the stale ID directly to both firstRangeSqueeze(song, activeRole) and firstCueSheetLead(song, activeRole, t). If the new song lacks that role, the first-action export is suppressed even though the new song has a valid lead. This is a current-song selection-boundary bug, not a firstCueSheetLead leaf bug.

First add the smallest realistic RED regression in Workspace.test.tsx: render song A, select a role that does not exist in song B, rerender the same Workspace with song B, export Download tonight's first-action sheet, and prove the CSV still contains song B's Tonight first row (and, where practical, that the first-range callout no longer consumes the absent stale role). Then make the narrowest root fix in Workspace.tsx: derive/reset the effective selected role against the current roleMap so all current-song role-specific behavior treats an absent stale ID as no selection, while preserving valid same-song filtering. Do not patch firstCueSheetLead to special-case this caller.

Touch only the owning Workspace source/test unless the RED proof demonstrates a strictly necessary adjacent change. No new branch/PR, no force-push/rebase, no gate weakening, no foreign-repo mutation, no dependency/workflow changes, no self-review or reviewer dispatch. Run the focused regression, relevant Workspace/Desktop suite, typecheck/lint and repository quickcheck/coverage gates exposed by the branch. Commit to this existing contributor branch and report the successor exact SHA plus RED→GREEN evidence. Do not resolve the review thread until the successor exact-head evidence supports it.

@opencode-agent Take the sole writer lease for the current canonical BandScope lane feat/workspace-cuesheet-first-action only while it still resolves to exact head c9965e59561330ff2a9faf5eb71a11db46f22ecd over protected develop@749511c3ad4000090048718f685c6bee6b3d2c25. The prior leases were bound to predecessor f177efac... and are superseded by branch movement. Apply superpowers:using-superpowers, receiving-code-review, systematic-debugging, test-driven-development, and verification-before-completion. Immediately before writing, refetch head/base, apps/desktop/src/features/workspace/Workspace.tsx, the stale-role Workspace regression(s), docs/doctoring/cuesheet-first-action.md, and unresolved threads PRRT_kwDORjvEXs6drW0g / PRRT_kwDORjvEXs6d1SCW; abort/adapt if any owning ref/blob moved. No new branch/PR, force-push/rebase, gate weakening, dependency/workflow changes, foreign-repository mutation, or self-review.

Fresh exact-current source still exposes the stale-role authority defect: activeRoleDetails validates through roleMap.get(activeRole), but firstRangeSqueeze(song, activeRole) and the cue-sheet lead path still consume the raw retained activeRole. When the same Workspace instance is rerendered with a song that lacks the previously selected role, the new song has valid first-range/first-action evidence but the card/export can fail closed against an ID that is no longer current-song authority. Devin thread PRRT_kwDORjvEXs6drW0g is therefore still valid on c9965e5....

TDD first. Add/strengthen the smallest realistic RED UI regression: render song A, select a role absent from song B, rerender the same Workspace with song B, then prove (a) the first-range callout derives from song B rather than showing the missing-range fallback caused by the stale role and (b) Download tonight's first-action sheet leads with song B's valid first-action row. Preserve correct filtering when the selected role still exists in the replacement song. Capture predecessor RED evidence before production change.

Repair the owning Workspace selection boundary, not the leaf helpers. Derive one validated current-song role, e.g. effectiveActiveRole = activeRole && roleMap.has(activeRole) ? activeRole : null, and use it consistently for current-song buyer-visible per-role derivations that would otherwise treat a stale ID as authority, at minimum firstRangeSqueeze and firstCueSheetLead; inspect adjacent consumers before changing them and keep the patch narrow. Do not weaken firstRangeSqueeze or firstCueSheetLead fail-closed validation.

After executable GREEN, address the independent documentation thread only if still current: in docs/doctoring/cuesheet-first-action.md, diagram node B must name the helper actually called, firstRangeSqueezeTarget, rather than firstRangeSqueeze. Do not broaden documentation.

Run the focused stale-role regression RED→GREEN, relevant firstRangeSqueeze/firstCueSheetLead and Workspace tests, then full desktop Vitest with configured coverage, desktop typecheck/lint, and repository quickcheck. Commit only the causal Workspace/test repair plus the one-line diagram correction on this canonical branch. Refetch successor exact head/base and report exact evidence. Resolve only the two addressed current threads after successor evidence supports them; do not dispatch or manufacture approval.
