v0.7.5 - 2026-05-10 - P0-P6 omnibus close-every-gap

Replaces v0.7.4 at _canon.yaml::contract_version. Issued via the
myco molt --contract v0.7.5 agent-callable verb.
synced_contract_version updated in lockstep.

What changed

Schema v2 → v3 (additive). New optional field
metrics.lint_dim_count: int | null. Substrates at v2 transparently
upgrade on next load_canon call. See
docs/migration/v0_7_4_to_v0_7_5.md
for operator notes (no operator action required).

Seven items shipped together (per
docs/primordia/v0_7_5_p0_to_p6_omnibus_craft_2026-05-10.md):

• P0 Owner's claude_desktop_config.json migrated myco.mcp →
  myco.boundary.mcp. MB8 shim sunset gate begins counting (≥7 cycles
  • ≥7 days zero-hit; earliest src/myco/mcp/ deletion = 2026-05-15).
• P1 Living Bets v0.7-MAJOR re-audit
  (docs/primordia/v0_7_5_living_bets_audit_2026-05-10.md)
  honors L0 cadence ("every MAJOR re-audits"; v0.7.0 missed; v0.7.5
  backfills). Bet stands; 3 ratification options (A/B/C) for owner.
  Status: DRAFT — AWAITING_OWNER_RATIFICATION.
• P2 First real schema migration since v0.6.0. anamorph subagent
  authored partial + composer + 11 tests + schema delta + 1100-word
  migration guide. _apply_upgraders now walks to the latest
  registered version. scripts/bump_version.py auto-refreshes
  metrics.test_count + metrics.lint_dim_count from live
  measurements every molt — closes the README/canon drift loop
  structurally. Cycle-detection regression caught and fixed.
• P3 First real federation E2E test in propagate's 7-minor history.
  tests/integration/fixtures/peer_substrate/ ships as a real second
  substrate; 5 tests exercise propagate() filesystem-to-filesystem.
• P4 Self-eat: ingested 5 v0.7.x crafts via the actual
  eat → assimilate → sporulate verb chain. Distilled synthesis at
  notes/distilled/d_v0-7-x-release-cycle-retrospective.md
  crystallizes 5 doctrinal observations (Two-hour blast-radius rule;
  Ratchet dims as eternal pruning; External-bug workaround discipline;
  Hotfix cadence honesty; L2 codification as the seal). Notes counts
  on Myco-self: integrated 2 → 7, distilled 1 → 2.
• P5 Chat-log ingestion adapter (7th adapter). Markdown
  (## user: / ## assistant: / ## system: headers, bold variants)
  • JSONL ({role, content} per line). Extension fast-path +
    content-sniff fallback. 16 tests. Credential deny-list extended
    (.aws_credentials.*).
• P6 Operational debt: README × 3 (en/zh/ja) "46 lint dimensions"
  → "50 lint dimensions". docs/contract_changelog.md v0.7.3 stub
  backfilled with retrospective entry. metrics.test_count /
  metrics.lint_dim_count now self-refreshing forever.

Test count delta

1568 → 1601 (+33: 11 schema upgrader + 5 federation + 16 chat-log + 1
parametrize-expansion).

Lint state

immune exit_code 0. Findings: 1 MEDIUM MB8 (shim hits 28 — sunset gate
counting from this release). Zero HIGH. Zero LOW (the 5 transient SE2
LOW findings on freshly-eaten notes cleared once their distilled-doc
back-references registered in the graph).

Cloud delta

• PyPI: myco-0.7.5-py3-none-any.whl + myco-0.7.5.tar.gz via
  trusted-publisher OIDC.
• MCP Registry: io.github.Battam1111/[email protected] server card via
  github-oidc, isLatest=true.
• GitHub Release: v0.7.5 with myco-0.7.5.zip attached.

Break from v0.7.4

Internal contract drift only: myco.core.canon._apply_upgraders's
recursion shape changed — it now walks to the latest registered
schema version instead of early-exiting at the first
KNOWN_SCHEMA_VERSIONS hit. Downstream code that asserted
intermediate v2 shape after load_canon must update assertions
(canon now lifts v1 → v2 → v3 in one call). Surface API: no breaks.
