v0.6.0 — 2026-04-28 — Unified evolution + thorough refactor (MAJOR-class per L0:223)

Full R-surface preserved; canon schema bump v1 → v2; subsystem count 5 → 7 (cycle + boundary promoted).
First MAJOR-class release per L0_VISION.md:223-228 cadence rule —
fires Living Bets re-audit (sibling craft v0_6_0_living_bets_audit_craft_2026-04-28.md).
SemVer label "0.6.0" reads MINOR by external naming convention; Myco
contract semantics treat it as MAJOR-class for review-cadence and
breaking-change-permission per craft v0.6.0 §F1.

Governing crafts

• docs/primordia/v0_6_0_unified_evolution_and_thorough_refactor_craft_2026-04-28.md (LANDED, owner-approved)
• docs/primordia/v0_6_0_living_bets_audit_craft_2026-04-28.md (LANDED; verb-surface wager survives un-falsified at 2026-Q2 model capability; v0.7 falsification experiment pre-registered)

What changed (major)

1. Cycle promoted to canonical 6th subsystem (canon.subsystems 5 → 6).
   Aligns L4 with L0_VISION.md:183 which named Cycle as 6th since v0.5.3.
   New L2 doctrine docs/architecture/L2_DOCTRINE/cycle.md.
   Withdrawn proposals: cycle→governance rename (violated L0:185-186 "No
   alternate vocabulary") and boundary subsystem creation (same).
2. Canon schema v1 → v2 via _v1_to_v2 upgrader composed of two
   named partials (per craft §F6/T30 narrowness):
   • _v1_to_v2_llm_policy_enum: system.no_llm_in_substrate: bool
     → system.llm_policy: "forbidden" | "opt-in" | "providers-declared"
     enum (default forbidden — preserves v0.5.6 P1 strict invariant).
   • _v1_to_v2_federation_peers_field: adds identity.federation_peers: []
     forward-compat infrastructure for L0 P5 federation planning.
     KNOWN_SCHEMA_VERSIONS = frozenset({"1", "2"}). v0.5.x substrates
     parse cleanly without warning; lint.dimensions sub-file extraction
     deferred to v2.1.
3. Lint dimension inventory 25 → 44 (+21 new dims). All ship at
   default-severity LOW with lint.severity_promotion ledger ramping
   to declared severity over 30 sessions of green observation:
   • Mechanical structural (9): PA2 (megafile LoC cap), PA3
     (surface pure-adapter), PA4 (core no-subsystem-deps), PA5
     (meta-subsystem layering), SC1 (canon JSON-Schema parity),
     DC5 (abstract-parent-allowlist canon-driven), MF3 (symbiont
     host-side artifact integrity), DI2 (hooks content R1+R2),
     AD1 (adapter silent-skip detection).
   • Semantic + metabolic (5): SE4 (reciprocal back-link), RL2
     (R3 sense-discipline signal), RL3 (R4 eat-discipline signal),
     MB4 (sporulated-reabsorbed integrity), MB6 (stale DRAFT/distilled).
   • Shipping + capability + plugin (3): SH2 (kernel-ahead-of-canon),
     CL1 (sampling capability gated on llm_policy), MP3 (plugin
     bytecode LLM-SDK audit).
   • R-revision additions (4): MB7 (resource_watch quota pressure),
     CL2 (OAuth token-residency policy), CL3 (sampling token clear),
     MF4 (overlay_verb subsystem validity).
4. Verb count 19 → 20: new intake verb (replaces unimplemented
   forage --digest-on-read); single-responsibility composer of
   forage + eat with strict-mode and adapter-failure-visibility.
5. Sporulate→reassimilate closed loop lands per L0 P4
   ("永恒迭代; integrated is not endpoint"). New
   digestion.reassimilate.reassimilate_integrated demotes integrated
   notes to stage: re_raw with audit trail; new
   digestion.promote_sporulated.promote_consumed_distilled lifts
   distilled notes consumed by crafts to stage: sporulated with
   propagated_doctrine: <docpath> reference. pipeline.NOTE_STAGES
   extends to include sporulated and re_raw.
6. MCP capability surface extended: new surface.mcp_resources
   (resources/list + resources/read with URI scheme myco://canon,
   myco://contract, myco://notes/integrated/{id},
   myco://docs/primordia/{slug}, myco://reflex/queue) + new
   surface.mcp_prompts (20 verb-guides + 2 workflow prompts).
   Resources honor system.resource_redaction default protected
   scope (federation_peers, identity.tags, system.governance hidden
   from non-OAuth-canon:full hosts). Resource-read injects R3-discipline
   ledger entry per craft §F8.
7. Symbionts populated at src/myco/symbionts/<host>.py (path
   preserved per extensibility.md:24-27 doctrine; boundary/host_integration/
   refactor withdrawn). v0.6.0 ships 5 of 11 host adapters with full
   discover/install_basic/install_deep/uninstall four-function
   protocol: claude-code, cursor, cowork, vscode, continue-dev. The
   remaining 6 (cline, jetbrains, zed, goose, windsurf, codex-cli /
   gemini-cli / openclaw / claude-desktop) ship as v0.6.x ecosystem-thawed
   patches per craft §F23 dual-layer versioning.
8. Activity cleanup: 9-day-stalled DRAFT craft dogfood_v0_5_3_smoke_craft_2026-04-18.md
   moved to docs/primordia/_excreted/; 2 distilled notes
   (d_legacy_alias_test.md, d_v0_5_3_dogfood_notes.md) moved to
   notes/distilled/_excreted/ (no doctrine payload, event-records
   only). MB6 dim guards future stale-DRAFT/distilled at 14d MEDIUM
   / 30d HIGH thresholds (canon-driven via lint.thresholds).

Aliases (deferred per digestion.md:120-122)

v0.5.2 CLI aliases (genesis, reflect, distill, perfuse,
session-end, craft, bump, evolve, scaffold) continue to
resolve at v0.6.0 with one-shot DeprecationWarning. Removal
remains scheduled at v1.0.0. v0.6.0 only upgrades the deprecation
banner severity; full removal awaits v1.0.0 per LANDED L2 doctrine
schedule (rejected craft §D9 acceleration was a P0 violation per
ChatGPT-as-critic [1.5-F]).

Governance tiering (NEW)

• High-risk craft (L0 five principles, R1-R7 number/semantics, llm_policy
  default flip, subsystem deletion): owner approval required.
• Medium-risk craft (new dim, new verb alias, fixable-set extension):
  agent-self-winnow + 7-session-7-day public window (max of both floors).
• Low-risk craft (typo, JSON-Schema description, test fixtures):
  agent-self-winnow only.
• Owner-veto via canon.governance.last_winnowed_proposals[].vetoed_at
  always-on. Public window measured in senesce_count >= 7 AND
  wall_clock_days >= 7 (whichever later).

Schema additions (canon)

• system.llm_policy (enum replaces v0.5.6 bool).
• identity.federation_peers (list, default empty).
• system.resource_redaction (paths/scopes for MCP resources).
• system.resource_watch (quota + LRU eviction + ETag fallback).
• system.governance (public window thresholds + token-residency policy).
• lint.severity_promotion (per-dim ramp ledger).
• lint.thresholds (stale-draft + stale-distilled cutoffs).
• lint.abstract_parent_allowlist (replaces DC2:158 hardcode; DC5 dim).
• system.write_surface.allowed adds examples/** (8 framework demos
  scope) and dist/** (CHANGELOG hatch hook).

Doctrine alignments

• L1_CONTRACT/protocol.md: editorial clarification — "writes" =
  substrate writes; symbiont host-side writes are extensions of the
  host's own config discipline (not a R6 rule amendment, not adding
  R8 — see craft §F25).
• L1_CONTRACT/versioning.md: dual-layer versioning (contract-frozen
  vs ecosystem-thawed) introduced per craft §F23.
• L1_CONTRACT/canon_schema.md: v2 schema described.
• L2_DOCTRINE/cycle.md: NEW (6th subsystem doctrine).
• L2_DOCTRINE/extensibility.md: per-host axis enforcement dim
  promoted from "reserved" to MF3.
• L3_IMPLEMENTATION/package_map.md: 5 → 6 subsystems; cycle
  canonicalized; boundary withdrawn; examples/** + dist/** added
  to write_surface; severity-promotion ledger pattern documented.
• L3_IMPLEMENTATION/symbiont_protocol.md: 5/11 host adapters
  shipped; uninstall path implemented; remaining 6 → v0.6.x.

Lessons learned (NEW pattern: dual-LLM critique)

The v0.6.0 craft was authored with parallel ChatGPT-as-critic +
Gemini-as-critic agents injecting Round 1.5 and Round 2.5 tensions
that single-perspective review would have missed. Specifically:

• ChatGPT [1.5-D] caught that L0:183 already named Cycle as 6th
  subsystem; the proposed rename to governance would have violated
  L0 directly. Corrected to "promote, don't rename."
• ChatGPT [1.5-F] caught that digestion.md:120-122 doctrine
  scheduled alias removal at v1.0.0; v0.6.0 acceleration was a doctrine
  violation. Corrected to "warn at v0.6.0, remove at v1.0.0."
• Gemini [G1.5-3] caught that 11 host × 3 OS × 2 arch matrix was
  being tested as 1 cell; planned matrix CI for symbiont suite.
• Gemini [G1.5-6] caught that resources/list of myco://canon
  would leak federation_peers (potentially internal substrate URLs)
  to any MCP host. Corrected to default-redacted scope + OAuth-gated
  raw view.
• ChatGPT [2.5-α] caught that v0.6 MAJOR mandates Living Bets
  re-audit; sibling craft authored.

This dual-critique pattern is itself doctrine-worthy. v0.6.x or v0.7
may codify it as a craft_protocol_version: 2 enhancement.

Migration

A docs/migration/v0_5_24_to_v0_6_0.md (deferred to v0.6.x ecosystem-thawed
patch) details operator-visible deltas. Headline:

• Substrates auto-upgrade canon schema v1→v2 on first hunger; no
  operator action.
• All v0.5.x verb invocations continue working; deprecation banners
  louder.
• New myco intake verb available.
• New myco:// MCP resources visible in host UIs.

Acceptance

• myco hunger reports contract_version v0.6.0; substrate_pulse confirms.
• myco immune runs 25 dim baseline (kernel cache); on entry-points
  refresh expands to 44 dims, each at LOW per severity_promotion.
• myco brief shows 6 subsystems including cycle.
• DRAFT craft excretion verified by myco traverse orphan count
  reduction.
• Living Bets audit craft passes myco winnow.
