Cross-AI plan convergence loop — automates the manual chain: gsd-plan-phase N → gsd-review N --codex → gsd-plan-phase N --reviews → gsd-review N --codex → ... Plan-phase runs inline (bare Skill at depth 0) so it can spawn gsd-planner/gsd-plan-checker at depth 1. Review runs inside an isolated Agent (leaf skill — Bash only, no sub-agents needed). Orchestrator only does: init, loop control, parse CYCLE_SUMMARY for HIGH and actionable non-HIGH counts, stall detection, escalation.

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.

3. Validate Phase + Pre-flight Gate

4. Initial Planning (if no plans exist)

If has_plans is true: Skip to step 5. Display: Plans found: {plan_count} PLAN.md files — skipping initial planning.

If has_plans is false:

Display: ◆ No plans found — running initial planning inline... (plan-phase runs here in the orchestrator — no output until planning is complete, ~1–5 min; expected, not a freeze)

Skill(skill="gsd-plan-phase", args="{PHASE} {GSD_WS}")

Run plan-phase inline (do NOT wrap it in Agent()). The convergence orchestrator runs at depth 0 with Agent available, so inline plan-phase can spawn gsd-planner and gsd-plan-checker at depth 1 — the one level of nesting that works on Claude Code. Wrapping plan-phase in Agent() would push it to depth 1 where the Agent tool is absent, preventing it from spawning any sub-agents. Wait until plan-phase completes and PLAN.md files are committed before continuing.

After plan-phase completes, verify plans were created. This asks "did initial planning write files to disk" — a planner-produced-nothing check, not outstanding-work counting — so it takes the PHYSICAL set (plan_count_all, status: superseded INCLUDED, #3218):

PLAN_COUNT=$(gsd_run query find-phase "${PHASE}" | jq -r '.plan_count_all // 0')

If PLAN_COUNT == 0: Error — initial planning failed. Exit.

Display: Initial planning complete: ${PLAN_COUNT} PLAN.md files created.

5. Convergence Loop

Initialize loop variables:

Complete the full review workflow. Do NOT return until REVIEWS.md is committed.

IMPORTANT — CYCLE_SUMMARY contract (required):
Your final response MUST include a machine-readable line of exactly this form:

  CYCLE_SUMMARY: current_high=<N> current_actionable=<M>

Where <N> is the integer count of HIGH-severity concerns that REMAIN UNRESOLVED in this cycle's findings.
Where <M> is the integer count of actionable MEDIUM/LOW concerns that REMAIN UNRESOLVED because the latest PLAN.md files do not yet incorporate them or explicitly defer/reject them.

Consensus gate (applies to NEWLY RAISED HIGHs only; evaluate before the counting rules below):
  This gate engages ONLY when 2 or more reviewers actually ran and produced a review section this
  cycle. With exactly one reviewer, skip this entire gate — a single reviewer's HIGH always counts,
  exactly as before.

  Classify each newly raised HIGH by what the claim ASSERTS, not by whether it happens to contain a
  file:line citation:
    - EXISTENCE-CLASS — asserts that a named symbol, file, path, flag, commit, or ID exists,
      is absent, or says something specific ("X does not exist", "the plan cites Y which is missing",
      "file Z contains Q").
    - JUDGMENT-CLASS — asserts a design or correctness property ("no idempotency on retried writes",
      "race between A and B", "missing rate limit"). A judgment-class HIGH stays judgment-class even
      when it cites a file for context.

  A HIGH raised by 2+ reviewers is corroborated and always counts.

  For a HIGH raised by exactly ONE reviewer:
    - EXISTENCE-CLASS — counts only if the source-grounding pass independently confirms it against
      real project source, or another reviewer raised the same or a materially overlapping concern
      (i.e. it lands in REVIEWS.md's Consensus Summary "Agreed Concerns").
    - JUDGMENT-CLASS — counts UNLESS that reviewer's own section OPENS with an evidence-quality
      discount marker blockquote: `[reviewed-without-source-citations]` or
      `[reviewed-without-repo-access]`, or the reviewer is a diff-only lane (CodeRabbit). The marker
      must be the LEADING blockquote of that reviewer's section — a review that merely quotes a
      marker while discussing it is NOT marked. Corroboration by another reviewer overrides the
      marker and the HIGH counts.

  Judgment-class findings are deliberately NOT subject to corroboration. Different reviewers catch
  materially different classes of issue, so requiring two of them to independently raise the same
  architectural concern would suppress exactly the findings a multi-reviewer setup exists to surface.

  FAIL OPEN: if EVERY reviewer that ran this cycle carries a discount marker, this gate does not
  apply at all — count as if it were absent. A gate must never manufacture convergence out of a
  cycle in which nothing was verified.

  A HIGH suppressed by this gate is still listed under "## Current HIGH Concerns", tagged
  `(single-reviewer, unconfirmed)`. It is excluded from current_high only — never silently dropped,
  and never removed from the report.

  This gate governs current_high only. current_actionable is unaffected.

Counting rules:
  INCLUDE in the count:
    - Newly raised HIGHs in this cycle (subject to the consensus gate above)
    - PARTIALLY RESOLVED HIGHs: concern acknowledged and a mitigation is in progress, but not yet verified/completed
    - Previously raised HIGHs that are still unresolved

  EXCLUDE from the count:
    - FULLY RESOLVED HIGHs: concern addressed with verification complete (closed ticket, verification log, or reviewer sign-off)
    - HIGH mentions in retrospective/summary tables comparing cycles
    - Quoted excerpts from prior reviews referencing past HIGH items
    - MEDIUM/LOW concerns that are already incorporated into a PLAN.md task, action, acceptance_criteria, verify command, must_haves item, threat model, artifact list, or explicit deferral/rejection rationale

Definitions:
  PARTIALLY RESOLVED — concern acknowledged and mitigation is in progress but not yet verified/completed (e.g., open ticket exists but fix not landed).
  FULLY RESOLVED — concern addressed with verification complete (closed ticket, verification log, or explicit reviewer sign-off confirming closure).
  ACTIONABLE — a non-HIGH review finding that would be invisible to /gsd:execute-phase unless it is incorporated into PLAN.md or explicitly deferred/rejected in PLAN.md.

Your final response MUST also include this section immediately after the CYCLE_SUMMARY line:

## Current HIGH Concerns
[List each unresolved HIGH with a brief description, one per bullet]
[If none: write exactly 'None.']

## Current Actionable Non-HIGH Concerns
[List each unresolved actionable MEDIUM/LOW with a brief description and the PLAN.md change still needed, one per bullet]
[If none: write exactly 'None.']
These two sections MUST be the final content of your response, in this exact order, with no additional "## " headings after them (the source-grounding "Verification coverage" block is appended to REVIEWS.md, not to this return message).",
  mode="auto"
)

Source-grounding pass (config: plan_review.source_grounding, default on)

Run this pass unless plan_review.source_grounding is false. It verifies every symbol the plan cites against the project source before approval, catching hallucinated symbols at review time instead of execution time.

1. Enumerate cited symbols. List every referenced symbol by kind, quoting the plan line for each (coverage must be auditable): decorators (@name), classes/methods (Class.method), functions (module.function), CLI flags (--name), file paths, dataclass/struct fields.
2. Exclude new artifacts. Do NOT verify symbols the plan declares under its "Artifacts this phase produces" section — those are created by this phase, not references to existing code.
3. Resolve each remaining symbol using the effective authority adapter (resolved deterministically — see step 4a):
   • grep — ripgrep / Read the source; confirm the name appears as a real declaration.
   • intel — consult .planning/intel/API-SURFACE.md / api-map.json (only when intel.enabled). Record one verdict per symbol: VERIFIED (quote file:line), MISSING (adapter can check this language/kind and the symbol is absent), AMBIGUOUS (multiple candidates), or UNCHECKABLE (adapter cannot analyze this language/kind — e.g. non-JS under intel, or any signature under grep). Never treat UNCHECKABLE as verified or missing. 4a. Resolve effective authority (deterministic — replaces manual intel.enabled reasoning):

   EFFECTIVE_AUTHORITY=$(gsd_run drift-guard authority --raw)
   

4. Severity & gating — classify each symbol's verdict using the seam (do not apply the table manually):

   # For each symbol, e.g.:
   RESULT=$(gsd_run drift-guard severity --status <verdict> --authority "$EFFECTIVE_AUTHORITY")
   # $RESULT is JSON: {"severity":"…","hardBlock":true|false}
   

   • hardBlock: true (HIGH at authority lsp/scip) — stops the review cycle immediately; do not proceed until the plan author resolves the missing symbol.
   • hardBlock: false, severity needs-acknowledgement — plan proceeds only if the author confirms the symbol is genuinely new or dynamically resolved, and that acknowledgement is recorded.
   • AMBIGUOUS → MEDIUM. UNCHECKABLE → INFO.
   • Signature mismatches cannot be asserted under grep/intel; report the signature as UNCHECKABLE.
5. Coverage block. Append a "Verification coverage" section to REVIEWS.md listing every UNCHECKABLE/skipped symbol and why — a clean review must never silently mean "nothing was checked."

Cross-artifact fact-drift pass (same gate: plan_review.source_grounding)

Run this pass whenever the source-grounding pass ran — it is the second axis of the same drift guard, gated by the same plan_review.source_grounding key and adding no config surface of its own. Where source-grounding asks "does this symbol exist in the source?", this asks "does the project state the same fact in two planning artifacts, and do the two disagree?" Because each phase runs in a fresh context, an agent typically reads only one artifact and trusts it, so a stale duplicate silently steers it wrong.

Key on knowledge, not on similar text. DRY is about a single authoritative representation of a piece of knowledge. Two passages that merely read alike, or that restate one fact at different levels of detail, are NOT drift. Only a contradiction is.

1. Phase status — decided by the seam, not by judgment. Do not eyeball this axis:

   DRIFT=$(gsd_run drift-guard phase-status --phase "${PHASE}")
   # $DRIFT is JSON: {"verdict":"consistent|lag|drifted|uncheckable","stateStatus":…,"roadmapStatus":…}
   

   • drifted — STATE.md and ROADMAP.md contradict each other. Report it; the authority is STATE.md.
   • lag — one lifecycle step apart between non-terminal statuses. NOT a finding.
   • consistent — nothing to report.
   • uncheckable — a document was absent or carried a status outside both vocabularies. Record it in the coverage block; never read it as consistent.

   Completeness is terminal: when exactly one side says the phase is complete, the verdict is drifted and never lag, however few steps apart the two words look.

2. Pair up the remaining facts by judgment. The authority column names the source of truth, so a finding can say which side to keep:

   Fact class	Artifact pair	Authority	Decided by
   Success criteria / must-have truths	ROADMAP.md Success Criteria ↔ PLAN.md must_haves.truths	ROADMAP.md	judgment
   Requirement IDs	ROADMAP.md **Requirements:** ↔ PLAN.md task requirement refs	ROADMAP.md	judgment
   Phase status	STATE.md status ↔ ROADMAP.md phase state	STATE.md	step 1 (deterministic)
   Glossary / domain term	CONTEXT.md Decisions ↔ PLAN.md usage of the term	CONTEXT.md	judgment

3. Judge each judgment pair. FLAG only when ALL THREE hold:

   1. both sides name the same fact — same requirement ID, same success criterion, or the same defined term; and
   2. the two representations contradict, one asserting what the other denies, rather than differing in wording or in level of detail; and
   3. the pair is one of the judgment pairs above.

4. Record. Emit each finding into REVIEWS.md beside the source-grounding coverage block, quoting both locations and naming the divergence and the authority, so the author can collapse the two copies to a single source of truth.

Do NOT flag: a wording-only difference that asserts the same thing; a fact that appears in one artifact only — single-source is the target state, not a finding; a PLAN that ADDS a truth beyond the roadmap Success Criteria, which is sanctioned (plans may add, never subtract); a lag verdict from step 1 — two non-terminal statuses a single lifecycle step apart, in either direction, since STATE.md is written at planning time independently of ROADMAP.md and can lead as readily as trail (a disagreement about completion is never lag, and step 1 already reports it as drifted); anything under CONTEXT.md's Claude's Discretion or Deferred Ideas, which are non-authoritative by design.

Report once, not twice — these belong to gsd-plan-checker: a PLAN that omits a roadmap Success Criterion is scope reduction (Dimension 7b); a requirement ID the ROADMAP never defines is requirement coverage (Dimension 1); two PLAN.md files in one phase disagreeing is cross-plan data contracts (Dimension 9).

Severity: advisory, never a blocker. This pass never sets hardBlock, and its findings contribute to neither HIGH_COUNT nor ACTIONABLE_COUNT — a project carrying pre-existing drift must still be able to converge, or an advisory check becomes an endless replan loop.

Coverage, never silence. If STATE.md or CONTEXT.md is absent, that axis is skipped and the skip is recorded in the same "Verification coverage" block. A clean pass must never mean "nothing was compared."

After agent returns, verify REVIEWS.md exists:

REVIEWS_FILE=$(ls ${phase_dir}/${padded_phase}-REVIEWS.md 2>/dev/null)

If REVIEWS_FILE is empty: Error — review agent did not produce REVIEWS.md. Exit.

5b. Extract unresolved counts from CYCLE_SUMMARY Contract

Do NOT grep REVIEWS.md for HIGH or actionable counts. REVIEWS.md accumulates history across cycles — resolved findings from prior cycles remain in the file as audit trail, inflating a raw grep count and causing false stall detection.

Parse HIGH_COUNT and ACTIONABLE_COUNT from the review agent's return message via the CYCLE_SUMMARY contract:

# Extract integers from "CYCLE_SUMMARY: current_high=N current_actionable=M" in the agent's return message
SUMMARY_LINE=$(echo "$REVIEW_AGENT_RETURN" | grep -oE 'CYCLE_SUMMARY:.*' | head -1)
HIGH_COUNT=$(echo "$SUMMARY_LINE" | grep -oE 'current_high=[0-9]+' | head -1 | grep -oE '[0-9]+$')
ACTIONABLE_COUNT=$(echo "$SUMMARY_LINE" | grep -oE 'current_actionable=[0-9]+' | head -1 | grep -oE '[0-9]+$')

if [ -z "$SUMMARY_LINE" ]; then
  echo "Review agent did not honor the CYCLE_SUMMARY contract — cannot determine unresolved review counts. Retry or switch reviewer."
  exit 1
fi

if [ -z "$HIGH_COUNT" ]; then
  echo "CYCLE_SUMMARY present but current_high is missing or malformed — expected integer, got non-numeric or absent value. Retry or switch reviewer."
  exit 1
fi

if [ -z "$ACTIONABLE_COUNT" ]; then
  echo "CYCLE_SUMMARY present but current_actionable is missing or malformed — expected integer, got non-numeric or absent value. Retry or switch reviewer."
  exit 1
fi

UNRESOLVED_COUNT=$((HIGH_COUNT + ACTIONABLE_COUNT))

# Extract the ## Current HIGH Concerns section from the agent's return message
HIGH_LINES=$(echo "$REVIEW_AGENT_RETURN" | awk '/^## Current HIGH Concerns/{found=1; next} found && /^##/{exit} found{print}')
ACTIONABLE_LINES=$(echo "$REVIEW_AGENT_RETURN" | awk '/^## Current Actionable Non-HIGH Concerns/{found=1; next} found && /^##/{exit} found{print}')

if [ "${HIGH_COUNT}" -gt 0 ] && [ -z "${HIGH_LINES}" ]; then
  echo "⚠ Review agent's CYCLE_SUMMARY reports ${HIGH_COUNT} HIGHs but did not provide ## Current HIGH Concerns section — continuing with incomplete escalation details."
fi

if [ "${ACTIONABLE_COUNT}" -gt 0 ] && [ -z "${ACTIONABLE_LINES}" ]; then
  echo "⚠ Review agent's CYCLE_SUMMARY reports ${ACTIONABLE_COUNT} actionable non-HIGH concerns but did not provide ## Current Actionable Non-HIGH Concerns section — continuing with incomplete escalation details."
fi

If HIGH_COUNT == 0 and ACTIONABLE_COUNT == 0 (converged):

gsd_run state planned-phase --phase "${PHASE}" --name "${phase_name}" --plans "${PLAN_COUNT}"

Display:

### GSD ► CONVERGENCE COMPLETE ✓

 No HIGH concerns remaining.
 No actionable MEDIUM/LOW review findings remain outside PLAN.md.

Exit — convergence achieved.

If HIGH_COUNT > 0 or ACTIONABLE_COUNT > 0: Continue to 5c.

5c. Stall Detection + Escalation Check

Display: ◆ Cycle {cycle}/{MAX_CYCLES} — {HIGH_COUNT} HIGH, {ACTIONABLE_COUNT} actionable non-HIGH review concerns found

Stall detection: If UNRESOLVED_COUNT >= prev_unresolved_count:

⚠ Convergence stalled — unresolved review concern count not decreasing
  ({UNRESOLVED_COUNT} unresolved concerns, previous cycle had {prev_unresolved_count})

Max cycles check: If cycle >= MAX_CYCLES:

If TEXT_MODE is true, present as plain-text numbered list:

Plan convergence did not complete after {MAX_CYCLES} cycles.
{HIGH_COUNT} HIGH concerns and {ACTIONABLE_COUNT} actionable non-HIGH concerns remain:

{HIGH_LINES}

{ACTIONABLE_LINES}

How would you like to proceed?

1. Proceed anyway — Accept plans with remaining review concerns and move to execution
2. Manual review — Stop here, review REVIEWS.md and address concerns manually

5d. Replan (Inline)

If under max cycles:

Update prev_unresolved_count = UNRESOLVED_COUNT.

Display: ◆ Replanning inline with review feedback... (plan-phase runs here in the orchestrator — no output until replanning is complete, ~1–5 min; expected, not a freeze)

Skill(skill="gsd-plan-phase", args="{PHASE} --reviews --skip-research {GSD_WS}")

Run plan-phase inline (do NOT wrap it in Agent()). Same rationale as step 4: the convergence orchestrator runs at depth 0 with Agent available, so inline plan-phase can spawn gsd-planner and gsd-plan-checker at depth 1. Wrapping in Agent() pushes plan-phase to depth 1 where the Agent tool is absent — the replan loop can never produce a revised plan when HIGHs are found. This is the root cause of bug #936. Actionable MEDIUM/LOW findings must be incorporated into executable PLAN.md content or explicitly deferred/rejected in the relevant PLAN.md before convergence can complete. Wait until plan-phase completes (outputs '## PLANNING COMPLETE') and updated PLAN.md files are committed before continuing.

After plan-phase completes → go back to step 5a (review again).

<success_criteria>

• Config gate checked before running — exits with enable instructions if workflow.plan_review_convergence is false
• Initial planning via inline Skill("gsd-plan-phase") if no plans exist — NOT wrapped in Agent() (bug #936: depth-1 Agent has no Agent tool)
• Review via Agent → Skill("gsd-review") — isolated Agent is correct; gsd-review is a Bash leaf with no sub-agent spawns; {GSD_WS} forwarded
• Replan via inline Skill("gsd-plan-phase --reviews") — NOT wrapped in Agent(); inline lets plan-phase spawn gsd-planner/gsd-plan-checker at depth 1
• Orchestrator only does: init, config gate, loop control, parse CYCLE_SUMMARY for HIGH and actionable non-HIGH counts, stall detection, escalation
• HIGH and actionable non-HIGH counts extracted from review agent's CYCLE_SUMMARY return message (not by grepping REVIEWS.md)
• Review agent prompt defines CYCLE_SUMMARY: current_high= current_actionable= contract with PARTIALLY/FULLY RESOLVED/ACTIONABLE definitions
• Abort with clear error if CYCLE_SUMMARY is absent; distinguish malformed from absent
• Warn if HIGH_COUNT > 0 but ## Current HIGH Concerns section is absent from return message
• Abort with clear error if current_actionable is absent or malformed
• Warn if ACTIONABLE_COUNT > 0 but ## Current Actionable Non-HIGH Concerns section is absent from return message
• The review Agent fully completes gsd-review before returning (plan-phase runs inline — no Agent wrap)
• Loop exits on: no HIGH concerns and no actionable non-HIGH concerns (converged) OR max cycles (escalation)
• Stall detection reported when total unresolved review concern count is not decreasing
• STATE.md updated on convergence completion </success_criteria>
