ESL lifecycle hop — when the cortex routes a non-trivial change to SPECTRA in an ESL-enabled project (tonberry MCP available), SPECTRA owns the proposed→specify hop: right-size, propose the change folder, emit the spec into it. Absent tonberry → produce the spec normally (ESL opt-in).

Decision-ready specifications via the SPECTRA cycle. Use for complex features (complexity ≥7/12), multi-component/service changes, ambiguous requirements needing structured decomposition, or any task where 'just start coding' would require significant rework. Produces a dual-format spec (Markdown + YAML/JSON), never code.

Load when reading any upstream artefact handed off to SPECTRA that carries a sibling .envelope.json. BLOCKING per ECL §6.2.2: the orchestrator MUST have verified the envelope's SHA-256 (eidolons verify-envelope --block / eidolons run --verify) and recorded a verify_pass before dispatch. If no verify_pass exists for the message_id, or a verify_fail is present, REFUSE to process the payload and hand back to the orchestrator. Symmetric receiver gate — every Eidolon enforces it identically.
