-## Planning from Verification Gaps
-
-Triggered by `--gaps` flag. Creates plans to address verification or UAT failures.
-
-**1. Find gap sources:**
-
-Use init context (from load_project_state) which provides `phase_dir`:
-
-```bash
-# Check for VERIFICATION.md (code verification gaps)
-ls "$phase_dir"/*-VERIFICATION.md 2>/dev/null
-
-# Check for UAT.md with diagnosed status (user testing gaps)
-grep -l "status: diagnosed" "$phase_dir"/*-UAT.md 2>/dev/null
-```
-
-**2. Parse gaps:** Each gap has: truth (failed behavior), reason, artifacts (files with issues), missing (things to add/fix).
-
-**3. Load existing SUMMARYs** to understand what's already built.
-
-**4. Find next plan number:** If plans 01-03 exist, next is 04.
-
-**5. Group gaps into plans** by: same artifact, same concern, dependency order (can't wire if artifact is stub → fix stub first).
-
-**6. Create gap closure tasks:**
-
-```xml
-
- {artifact.path}
-
- {For each item in gap.missing:}
- - {missing item}
-
- Reference existing code: {from SUMMARYs}
- Gap reason: {gap.reason}
-
- {How to confirm gap is closed}
- {Observable truth now achievable}
-
-```
-
-**7. Assign waves using standard dependency analysis** (same as `assign_waves` step):
-- Plans with no dependencies → wave 1
-- Plans that depend on other gap closure plans → max(dependency waves) + 1
-- Also consider dependencies on existing (non-gap) plans in the phase
-
-**8. Write PLAN.md files:**
-
-```yaml
----
-phase: XX-name
-plan: NN # Sequential after existing
-type: execute
-wave: N # Computed from depends_on (see assign_waves)
-depends_on: [...] # Other plans this depends on (gap or existing)
-files_modified: [...]
-autonomous: true
-gap_closure: true # Flag for tracking

+start of execution when `--gaps` flag is detected or gap_closure mode is active.
-
-## Planning from Checker Feedback
-
-Triggered when orchestrator provides `` with checker issues. NOT starting fresh — making targeted updates to existing plans.
-
-**Mindset:** Surgeon, not architect. Minimal changes for specific issues.
-
-### Step 1: Load Existing Plans
-
-```bash
-cat .planning/phases/$PHASE-*/$PHASE-*-PLAN.md
-```
-
-Build mental model of current plan structure, existing tasks, must_haves.
-
-### Step 2: Parse Checker Issues
-
-Issues come in structured format:
-
-```yaml
-issues:
- - plan: "16-01"
- dimension: "task_completeness"
- severity: "blocker"
- description: "Task 2 missing element"
- fix_hint: "Add verification command for build output"
-```
-
-Group by plan, dimension, severity.
-
-### Step 3: Revision Strategy
-
-| Dimension | Strategy |
-|-----------|----------|
-| requirement_coverage | Add task(s) for missing requirement |
-| task_completeness | Add missing elements to existing task |
-| dependency_correctness | Fix depends_on, recompute waves |
-| key_links_planned | Add wiring task or update action |
-| scope_sanity | Split into multiple plans |
-| must_haves_derivation | Derive and add must_haves to frontmatter |
-
-### Step 4: Make Targeted Updates
-
-**DO:** Edit specific flagged sections, preserve working parts, update waves if dependencies change.
-
-**DO NOT:** Rewrite entire plans for minor issues, add unnecessary tasks, break existing working plans.
-
-### Step 5: Validate Changes
-
-- [ ] All flagged issues addressed
-- [ ] No new issues introduced
-- [ ] Wave numbers still valid
-- [ ] Dependencies still correct
-- [ ] Files on disk updated
-
-### Step 6: Commit
-
-```bash
-node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" commit "fix($PHASE): revise plans based on checker feedback" --files .planning/phases/$PHASE-*/$PHASE-*-PLAN.md
-```
-
-### Step 7: Return Revision Summary
-
-```markdown

-## Planning from Cross-AI Review Feedback
-
-Triggered when orchestrator sets Mode to `reviews`. Replanning from scratch with REVIEWS.md feedback as additional context.
-
-**Mindset:** Fresh planner with review insights — not a surgeon making patches, but an architect who has read peer critiques.
-
-### Step 1: Load REVIEWS.md
-Read the reviews file from ``. Parse:
-- Per-reviewer feedback (strengths, concerns, suggestions)
-- Consensus Summary (agreed concerns = highest priority to address)
-- Divergent Views (investigate, make a judgment call)
-
-### Step 2: Categorize Feedback
-Group review feedback into:
-- **Must address**: HIGH severity consensus concerns
-- **Should address**: MEDIUM severity concerns from 2+ reviewers
-- **Consider**: Individual reviewer suggestions, LOW severity items
-
-### Step 3: Plan Fresh with Review Context
-Create new plans following the standard planning process, but with review feedback as additional constraints:
-- Each HIGH severity consensus concern MUST have a task that addresses it
-- MEDIUM concerns should be addressed where feasible without over-engineering
-- Note in task actions: "Addresses review concern: {concern}" for traceability
-
-### Step 4: Return
-Use standard PLANNING COMPLETE return format, adding a reviews section:
-
-```markdown
-### Review Feedback Addressed
-
-| Concern | Severity | How Addressed |
-|---------|----------|---------------|
-| {concern} | HIGH | Plan {N}, Task {M}: {how} |

-### Review Feedback Deferred

-| {concern} | {why — out of scope, disagree, etc.} |
