* fix(#2402): honor response_language across orchestrator output + UAT checkpoint renderer Replays the in-flight bot branch fix/2402-response-language-orchestrator-coverage (seven commits, never pushed) onto current origin/next as a single squashed commit. The original work was substantial and correct; this commit preserves its full scope, trimmed where rebase conflicts + workflow size budgets required it. Three independent layers where response_language was being dropped are closed: Layer 1 — orchestrator-facing directives across workflows. Adds the strong "All user-facing output in this workflow MUST be presented in {response_language}; technical terms, code, paths, and subagent prompts stay in English" directive to ~40 workflows that previously either lacked it entirely (verify-work, new-project, new-milestone, quick, manager, and ~35 more) or carried only the weak subagent-prompt-only form (plan-phase, execute-phase). The directive covers narration between tool calls and banner output, not just the AskUserQuestion prompts. Layer 2 — UAT checkpoint renderer (src/uat.cts). buildCheckpoint now accepts an optional responseLanguage parameter and renders the frame strings ("CHECKPOINT: Verification Required", "Type `pass` or describe what's wrong.") in any of 9 languages (English/Spanish/French/German/Portuguese/Japanese/ Chinese/Korean/Italian) with an alias table covering ~30 input variants (en, es, español, ja, 日本語, etc.). cmdRenderCheckpoint reads config.response_language via loadConfig(cwd) and passes it through, so the byte-for-byte block verify-work.md reprints verbatim is already localized when written — preserving the anti-injection hygiene rule at verify-work.md (the model is forbidden to translate after the fact). CJK display width is computed by East Asian Width property ranges (W/F) so the right ║ border of the banner stays aligned for full-width characters. English fallback is byte-identical to the pre-fix behavior when response_language is unset or unrecognized. Layer 3 — literal English report templates in execute-phase. The top-of- workflow directive covers all template sites (templates are a structural source, not literal output). Inline render-language notes that previously sat at each template site were removed during the squash because they pushed execute-phase.md over its frozen pre-phase-6 byte ceiling (93600 — ADR-857 Phase 6 capstone). The single top directive covers the same surface with fewer bytes. Also extends src/docs.cts and src/init.cts to propagate response_language into the init JSON bundle of the additional workflows so the directive can read it. Tests added: - tests/uat.test.cjs: buildCheckpoint with unset/unrecognized language falls back to English default; recognized language swaps only the two frame strings while structural lines stay untouched; CJK display-width regression (independent recomputation of East Asian Width W/F ranges). - tests/workspace.test.cjs, tests/docs-update.test.cjs: response_language wiring through docs.cts/init.cts. References: #2402; reporter's three-layer triage + Layer-4 follow-up; the byte-for-byte anti-injection hygiene rule at verify-work.md (the reason Layer 2 must be renderer-side, not model-translated). This is a squash of the in-flight bot branch — seven commits representing the original implementation plus its subsequent fix/CJK-padding/test/ changeset/regen cycles, none of which were ever pushed or PR'd. The squash captures the final coherent state. * chore(#2402): backfill pr:2457 in .changeset/2402-response-language-orchestrator-coverage.md * chore(#2402): regen golden + size baseline after rebase against #2315 (PR #2451) Rebase conflicts were entirely in generated artifacts (golden-install-parity fixtures + workflow-size-baseline.json). After taking theirs during rebase, regenerated cleanly against the merged source tree.

If response_language is set: All user-facing questions, prompts, and explanations in this workflow MUST be presented in {response_language}. Technical terms, code, file paths, and subagent prompts stay in English — only user-facing output is translated.

--last N→ MODE=last, COUNT=N (integer, default 10 if N missing)--phase NN→ MODE=phase, TARGET_PHASE=NN (two-digit phase number)--plan NN-MM→ MODE=plan, TARGET_PLAN=NN-MM (phase-plan ID)
If no valid argument is provided, display usage and exit:
Usage: /gsd:undo --last N | --phase NN | --plan NN-MM
Modes:
--last N Show last N GSD commits for interactive selection
--phase NN Revert all commits for phase NN
--plan NN-MM Revert all commits for plan NN-MM
Examples:
/gsd:undo --last 5
/gsd:undo --phase 03
/gsd:undo --plan 03-02
MODE=last:
Run:
git log --oneline --no-merges -${COUNT}
Filter for GSD conventional commits matching type(scope): message pattern (e.g., feat(04-01):, docs(03):, fix(02-03):).
Display a numbered list of matching commits:
Recent GSD commits:
1. abc1234 feat(04-01): implement auth endpoint
2. def5678 docs(03-02): complete plan summary
3. ghi9012 fix(02-03): correct validation logic
Text mode (workflow.text_mode: true in config or --text flag): Set TEXT_MODE=true if --text is present in $ARGUMENTS OR text_mode from init JSON is true. When TEXT_MODE is active, replace every AskUserQuestion call with a plain-text numbered list and ask the user to type their choice number. This is required for non-Claude runtimes (OpenAI Codex, Gemini CLI, etc.) where AskUserQuestion is not available.
Use AskUserQuestion to ask:
- question: "Which commits to revert? Enter numbers (e.g., 1,3) or 'all'"
- header: "Select"
Parse the user's selection into COMMITS list.
MODE=phase:
Read .planning/.phase-manifest.json if it exists.
If the file exists and manifest.phases?.[TARGET_PHASE]?.commits is a non-empty array:
- Use
manifest.phases[TARGET_PHASE].commitsentries as COMMITS (each entry is a commit hash)
If the file does not exist, or manifest.phases?.[TARGET_PHASE] is missing:
- Display: "Manifest has no entry for phase ${TARGET_PHASE} (or file missing), falling back to git log search"
- Fallback: run git log and filter for the target phase scope:
git log --oneline --no-merges --all | grep -E "\(0*${TARGET_PHASE}(-[0-9]+)?\):" | head -50 - Use matching commits as COMMITS
MODE=plan:
Run:
git log --oneline --no-merges --all | grep -E "\(${TARGET_PLAN}\)" | head -50
Use matching commits as COMMITS.
Empty check:
If COMMITS is empty after gathering:
No commits found for ${MODE} ${TARGET}. Nothing to revert.
Exit cleanly.
**Applies when MODE=phase or MODE=plan.**Skip this step entirely for MODE=last.
MODE=phase:
Read .planning/ROADMAP.md inline.
Search for phases that list a dependency on the target phase. Look for patterns like:
- "Depends on: Phase ${TARGET_PHASE}"
- "Depends on: ${TARGET_PHASE}"
- "depends_on: [${TARGET_PHASE}]"
For each dependent phase N found:
- Check if
.planning/phases/${N}-*/directory exists - If directory exists, check for any PLAN.md or SUMMARY.md files inside it
If any downstream phase has started work, collect warnings:
⚠ Downstream dependency detected:
Phase ${N} depends on Phase ${TARGET_PHASE} and has started work.
MODE=plan:
Extract the phase number from TARGET_PLAN (the NN part of NN-MM). Extract the plan number (the MM part).
Look for later plans in the same phase directory (.planning/phases/${NN}-*/). For each later plan (plans with number > MM):
- Read the later plan's PLAN.md
- Check if its
<files>sections orconsumesfields reference outputs from the target plan
If any later plan references the target plan's outputs, collect warnings:
⚠ Intra-phase dependency detected:
Plan ${LATER_PLAN} in phase ${NN} references outputs from plan ${TARGET_PLAN}.
If any warnings exist (from either mode):
- Display all warnings
- Use AskUserQuestion with approve-revise-abort pattern:
- question: "Downstream work depends on the target being reverted. Proceed anyway?"
- header: "Confirm"
- options: Proceed | Abort
If user selects "Abort": exit with "Revert cancelled. No changes made."
Display the confirmation gate using approve-revise-abort pattern from gate-prompts.md.Show:
The following commits will be reverted (in reverse chronological order):
{hash} — {message}
{hash} — {message}
...
Total: {N} commit(s) to revert
Use AskUserQuestion:
- question: "Proceed with revert?"
- header: "Approve?"
- options: Approve | Abort
If "Abort": display "Revert cancelled. No changes made." and exit. If "Approve": ask for a reason:
AskUserQuestion(
header: "Reason",
question: "Brief reason for the revert (used in commit message):",
options: []
)
Store the response as REVERT_REASON. Continue to execute_revert.
**HARD CONSTRAINT: Use git revert --no-commit. NEVER use git reset (except for conflict cleanup as documented below).**Dirty-tree guard (run first, before any revert):
Run git status --porcelain. If the output is non-empty, display the dirty files and abort:
Working tree has uncommitted changes. Commit or stash them before running /gsd:undo.
Exit immediately — do not proceed to any revert operations.
Sort COMMITS in reverse chronological order (newest first). If commits came from git log (already newest-first), they are already in correct order.
For each commit hash in COMMITS:
git revert --no-commit ${HASH}
If any revert fails (merge conflict or error):
- Display the error message
- Run cleanup — handle both first-call and mid-sequence cases:
# Try git revert --abort first (works if this is the first failed revert) git revert --abort 2>/dev/null # If prior --no-commit reverts already staged cleanly before this failure, # revert --abort may be a no-op. Clean up staged and working tree changes: git reset HEAD 2>/dev/null git restore . 2>/dev/null - Display:
╔══════════════════════════════════════════════════════════════╗ ║ ERROR ║ ╚══════════════════════════════════════════════════════════════╝ Revert failed on commit ${HASH}. Likely cause: merge conflict with subsequent changes. **To fix:** Resolve the conflict manually or revert commits individually. All pending reverts have been aborted — working tree is clean. - Exit with error.
After all reverts are staged successfully, create a single commit:
For MODE=phase:
git commit -m "revert(${TARGET_PHASE}): undo phase ${TARGET_PHASE} — ${REVERT_REASON}"
For MODE=plan:
git commit -m "revert(${TARGET_PLAN}): undo plan ${TARGET_PLAN} — ${REVERT_REASON}"
For MODE=last:
git commit -m "revert: undo ${N} selected commits — ${REVERT_REASON}"
