0.11.1 — 2026-06-11 — Embedded-First Schema Validation

Release Notes

Patch release fixing a v0.11.0 regression where MCP tools/call rejected the
documented until/timeout_ms args on loom.web.navigate with a misattributed
schema_violation (field 'params' expected field_unknown got object) while
web.wait_for accepted the same params. Root cause: the daemon validated against
per-method schema files on disk that loom postinstall never content-refreshes, so a
pre-settle-capture web.navigate.json survived upgrades; #152's fail-closed validation
then enforced the stale schema. (#176, fixes #175)

Fixed

• Embedded-first schema validation (#176). The daemon now validates builtin action
  methods against the schemas compiled into the binary (BUILTIN_SCHEMAS moved to
  loom-shared) — binary version == schema version, always. Disk schema files act only
  as an overlay for methods unknown to the binary (compiled fail-closed); a stale
  builtin mirror is logged with remediation and ignored. The exact regression
  (web.navigate + until/timeout_ms over MCP) is pinned by a class-level test that
  validates EVERY builtin action method against its full documented arg set.
• schema_violation errors name the real field, the method, and the allowed
  properties — e.g. schema violation: web.navigate: unknown field 'bogus' (schema allows: session, timeout_ms, until, url) — instead of blaming the envelope word
  params. The error data block gains additive method and allowed fields.
• loom postinstall refreshes stale schema mirrors (atomic write); the receipt
  reports a refreshed count alongside the existing populated/skipped shapes.

Changed

• Builtin action methods are validated from first boot — the pre-postinstall
  empty-registry validation bypass is gone (fail-closed, consistent with #152).
  Hand-edits to builtin schema mirror files are no longer honored (loud warning;
  overlay extras for unknown methods remain supported). rpc.schemas'
  source_wit_sha256 is now machine-independent for stock installs.
