Changes

• Preserve opaque JSON and argument bytes in canonical payloads using explicit byte framing, including Extra keys, tool parameters, metadata and strategy settings.
• Record concrete effective prompt and tool visibility, keeping hook consequences presence-sensitive and canonical history separate from request-only additions.
• Dispatch the Engine-accepted request without rebuilding it after intent publication. Preserve independent retry inputs, maintenance ordering, recovery and resource disposal.
• Advance the exact store schema to 14 without migration. HTTP contracts are unchanged.

Tests

• Byte-preservation and actual source-to-physical-dispatch regressions failed before the correction and pass afterward.
• Coverage includes invalid framing, typed text versus opaque bytes, complete request/evidence equality, nested retry mutation, hook restoration and empty visibility, maintenance cancellation ordering, owned/copied history, metadata limits and incompatible stores.
• Full Go and race suites, vet, frontend tests, protocol/Wails freshness, installer checks, security/lint checks and Wails build passed.
