/myco-evolve

The user wants you to run the autopoietic kernel-evolution loop against the distilled note: $ARGUMENTS

This is the v0.6.14+ Cycle 自起 fruit—winnow—molt 闭环 orchestrator. It mechanizes the bridge from sporulate (distilled note) to a candidate kernel mutation (auto-craft PR), with owner-merge-gate as the only remaining synapse. The substrate kernel adds zero LLM dispatch; intelligence lives in the Claude Code Agent layer (you, plus the 3 fungal critics that primordium spawns).

Governing doctrine: docs/architecture/L2_DOCTRINE/cycle.md § "Cycle 自起 fruit—winnow—molt 闭环 (v0.6.14+)" + docs/architecture/L2_DOCTRINE/boundary.md § "Sixth seam (v0.6.14+)". Governing craft: docs/primordia/v0_6_14_cycle_autostart_fruit_winnow_molt_loop_craft_2026-04-29.md.

Pre-flight gates (refuse if any fails)

Run all checks before invoking any subagent. If any returns a refusal condition, report it to the user with a diagnosis and stop. Do NOT auto-correct.

1. Master switch on: myco sense --query "auto_propose_enabled" — if canon shows false, refuse with auto-evolve disabled per canon.governance.auto_propose_enabled: false.

2. Tracking issue seeded: read _canon.yaml::system.governance.auto_evolve_tracking_issue_id — if null, refuse with tracking issue not seeded; run scripts/seed_auto_evolve_tracking_issue.py first.

3. Rate limit: read .myco_state/last_auto_evolve.txt (if exists) — if last-run timestamp is within canon.governance.auto_evolve_min_wall_clock_seconds_between seconds of now, refuse with the wait time.

4. Daily budget: read .myco_state/auto_evolve_spend.json (if exists) — if today's spend exceeds canon.governance.auto_evolve_daily_budget_usd (when not null), refuse.

5. Distilled-hash cooldown: read the distilled note at notes/distilled/d_<distilled-slug>.md; compute sha256(content); check canon.governance.last_winnowed_proposals[] for any entry whose originating_distilled_hash matches AND was added within the last auto_evolve_distilled_hash_cooldown_senesce senesce calls. If matched, refuse with same-distilled cooldown active; same hash already auto-crafted recently.

6. Distilled severity threshold: read distilled note's frontmatter — if severity: is below canon.governance.auto_evolve_min_distilled_severity (default medium), refuse with distilled severity below threshold; LOW signals do not trigger auto-evolve.

7. Distilled exists + readable: if notes/distilled/d_<distilled-slug>.md does not exist or cannot be read, refuse.

Orchestration chain (run in order; stop on first failure)

If all 7 pre-flight gates pass, run this chain. Each step's failure mode is report to user + halt; do NOT attempt automated recovery beyond the per-step retry policy noted.

Step 1: Quarantine the distilled note

Read notes/distilled/d_<distilled-slug>.md. Apply:

• Strip ASCII control sequences 0x00-0x1F except \n (0x0A) and \t (0x09).
• Cap length at 32,768 bytes (truncate; preserve frontmatter intact).
• Prepend the marker [UNTRUSTED-INPUT-FROM-RAW-VIA-DISTILLED] so primordium and critics know the content originated from raw notes (which myco eat does not filter per L0 P2).

Pass the quarantined content to primordium in step 2. Record the original sha256 hash for canon.governance bookkeeping in step 7.

Step 2: Invoke primordium in autonomous mode

Use the primordium subagent (.claude/agents/primordium.md) with the autonomous-mode flag.

Pass primordium:

• The quarantined distilled content.
• The substrate root path.
• Instructions to: (a) draft Round 1 from the distilled's "Future axis" section, (b) spawn 3 fungal critics (mycoparasite / saprotroph / mycorrhiza) in parallel via the Task tool with the role-prompts in primordium.md § "Critic role-prompts", (c) synthesize Round 1.5 T-numbered tensions, (d) write Round 2 responses, (e) decide Round 3 status (LANDED / DRAFT / WITHDRAWN), (f) record the 3 critic agentIds in the craft's sub_agent_fanout_artifacts frontmatter.

primordium returns:

• The path to the drafted craft under docs/primordia/.
• The Round 3 status.
• The synthesized list of T-numbered tensions with severity classifications.
• The 3 critic agentIds.

If Round 3 is DRAFT (any HIGH critic veto unresolved) or WITHDRAWN: report to user, halt, do NOT proceed to step 3. The craft remains under docs/primordia/ for human review.

Step 3: Run winnow

If primordium returned LANDED:

Run myco winnow --proposal docs/primordia/<craft-filename>.md (Bash).

Expected: exit 0, verdict pass. If fail: report to user with the violations list, halt.

Step 4: Hypha feasibility trace

Use the hypha subagent (.claude/agents/hypha.md) with the LANDED craft path as input.

Hypha (read-only) traces the craft's "## 修订后 ... 完整 scope" section against the actual src/, identifies impl traction issues, and returns either feasibility: ok or feasibility: blocked: <reason>. If blocked, halt with the reason.

Step 5: Anamorph schema migration (conditional)

If the craft proposes any change to _canon.yaml::schema_version OR introduces a new top-level canon field:

Use the anamorph subagent (.claude/agents/anamorph.md) to draft the schema migration partials, tests, and migration guide entry. If the craft does not touch schema, skip this step.

If anamorph returns migration_blocked: <reason>, halt.

Step 6: Stipe in --branch-only mode

Use the stipe subagent (.claude/agents/stipe.md) with these arguments:

• --target-craft docs/primordia/<craft-filename>.md
• --path-allowlist <comma-separated paths from craft frontmatter path_allowlist: field>
• --branch-only

Stipe creates branch fruiting/<distilled-slug>-<YYYY-MM-DD>, implements the craft per scope, runs gate quintet, commits, pushes, opens PR via gh pr create with the craft summary + repo-relative path link as body. Returns the PR URL.

If gate quintet fails: stipe halts with the failing-gate diagnosis. Branch is not pushed. Report to user.

Step 7: Bookkeeping

After stipe returns the PR URL:

1. Append a new entry to canon.governance.last_winnowed_proposals[] (this is a write through myco molt — actually no, molt is for contract bumps. Let me reconsider.) — actually, append by direct canon edit through the substrate's canon-write API (Edit tool on _canon.yaml), since this is canon-bookkeeping, not contract version bump:

last_winnowed_proposals:
  - slug: <distilled-slug>
    craft_path: docs/primordia/<craft-filename>.md
    pr_url: <stipe-returned-PR-URL>
    pr_branch: fruiting/<distilled-slug>-<YYYY-MM-DD>
    originating_distilled_hash: <sha256 from step 1>
    landed_at: <ISO 8601 timestamp>
    senesce_count_at_landing: <current senesce_count from .myco_state>
    status: pending_owner_merge
    vetoed_at: null  # filled by senesce reaper if PR closed-without-merge
    merged_at: null  # filled by senesce reaper or owner manually if merged

2. Update .myco_state/last_auto_evolve.txt with the current ISO timestamp.

3. Update .myco_state/auto_evolve_spend.json with today's incremental spend (estimate ≈ 0.50 USD per /myco-evolve invocation — 1 primordium + 3 critics + 1 hypha + optional anamorph + 1 stipe).

Step 8: Report to user

Final report shape:

/myco-evolve <distilled-slug>: <SHIPPED-PR | HALTED-AT-<step>>

Pipeline:
  Pre-flight gates:    [pass × 7]
  Step 1 (quarantine): <hash truncated to 12 hex>
  Step 2 (primordium): <craft path> (Round 3: <LANDED|DRAFT|WITHDRAWN>; <K> critics agentIds: <id1, id2, id3>)
  Step 3 (winnow):     <pass|fail>
  Step 4 (hypha):      <ok|blocked: ...>
  Step 5 (anamorph):   <not-needed | drafted: <path>>
  Step 6 (stipe):      <PR URL>
  Step 7 (canon):      last_winnowed_proposals[+1]
  Step 8 (state):      .myco_state/last_auto_evolve.txt updated

PR awaits owner review:
  URL: <PR URL>
  Branch: fruiting/<slug>-<date>
  Owner action: merge to ship, OR close-without-merge to veto (auto_revert.yml will reap).

Refusal vs halt

• Refusal (pre-flight gates 1-7) is silent on substrate state — nothing was written, nothing to roll back.
• Halt at steps 2-6 may have written docs/primordia/<craft-filename>.md (if step 2 LANDED then step 3+ failed). The craft stays as a record for human review; subsequent /myco-evolve invocations will catch it via step 5's distilled-hash cooldown gate.
• Halt at step 6 after gate quintet fails is the deepest point of failure. stipe should have refused; if it gets to the gate-quintet failure, the implementation it tried is in a state where some files may have been Edit'd but not committed. The user must inspect manually; do NOT auto-git restore.

Naming reminders

• Branch: fruiting/<distilled-slug>-<YYYY-MM-DD> (real fungal taxonomy; never auto-craft/).
• Critic role names in primordium spawns: mycoparasite / saprotroph / mycorrhiza (real fungal-ecology terms; satisfy L0:185-186).
• The orchestrator term is "Cycle 自起 fruit—winnow—molt 闭环" — NOT "autopoietic loop". The kernel words ("Cycle", "fruit", "winnow", "molt") are existing fungal vocabulary; "自起" (self-initiation) is descriptive.
