Recompute this MCP facade's hash-chained call receipts and report whether the chain verifies, the first diverging sequence when it does not, the receipt count checked, and the chain head. Use to audit whether recorded facade calls remain internally consistent; use cadence_renders_read when the target is a stored render record rather than the facade receipt chain. Behaviour: the verdict describes the chain before this call's own successful-call receipt is appended; the server has no network, authentication, or credential surface, and verification changes no record other than that normal receipt append. Returns an object with ok, diverging_seq, count, head, receipt_id, and receipt_head.

Create a local render proposal for one stored script, returning proposal_id, script_id, the stored voice, the optional note, applied: false, started: false, state: proposed, and the disposition text. Use when a render should be recorded for later human or production-pipeline review; do not use it to produce audio, because no render-start or render-apply tool exists on this server. An unknown script_id returns an error. Behaviour: each successful call writes one new proposal JSON file in the facade state area and appends a content-minimal hash receipt; it makes no network call, uses no credentials, invokes no synthesis engine, and is not idempotent because repeated calls create separate proposals. Returns the proposal plus receipt_id and receipt_head.

List Cadence's stored render and acceptance records with record_id, episode, take, voice, duration_s, state, and in_band_pct. Use this first to discover a valid record_id for cadence_renders_read. These are historical stored records, not live render status; this tool cannot start, retry, or inspect an in-progress synthesis. Behaviour: local file reads only, with no network, authentication, credentials, or audio playback; a successful call appends a content-minimal hash receipt. Returns an object with renders, receipt_id, and receipt_head, with null fields where a record does not carry a value.

Read one stored render or acceptance record in full by exact record_id, returning its episode, take, audio reference, voice, duration, basis, gate counts and percentage, state, source file, and stored receipt hash when the record is a sealed receipt. Use after cadence_renders_list when full evidence is needed; use cadence_receipts_verify for the facade's own call-receipt chain rather than a render record's stored receipt. An unknown record_id returns an error. Behaviour: local file read only; no synthesis, network, authentication, credentials, or external service; a successful call appends a content-minimal hash receipt. Returns the record plus receipt_id and receipt_head.

List the performance scripts stored in this Cadence checkout, with each script's identifier, repository-relative path, SHA-256 of its file bytes, and segment count. Use this first to discover a valid script_id for cadence_scripts_read or cadence_render_propose. This tool does not compile a score or start a render; use cadence_scripts_read when persona, segment text, and compiled-score evidence are needed. Behaviour: local stdio only, with no network, authentication, credentials, or external service; a successful call appends a content-minimal hash receipt (argument and result hashes only) to the facade receipt chain. Returns an object with scripts, receipt_id, and receipt_head.

Read one stored performance script and compile its performance score with Cadence's own compiler, returning the script identifier, path, file SHA-256, persona when present, segment texts, segment count, rule set, compiled span count, and canonical score SHA-256. Use when the actual script and compiler evidence are needed; use cadence_scripts_list for discovery only and cadence_render_propose only to record a non-executing render proposal. An unknown identifier returns an error and creates no proposal. Behaviour: local and deterministic for unchanged files; no synthesis, network, authentication, or credential use; a successful call appends a content-minimal hash receipt. Returns the script object plus receipt_id and receipt_head.

List the voice catalogue exactly as stored in this Cadence checkout's synthesis-adapter constants, returning voice_id, engine, adapter, timeout_secs, and an explanatory note for each entry. Use to identify the stored voice before reading scripts or proposing a render; use cadence_renders_list to find which voice a stored render record used. This tool cannot add, select, change, or certify a voice and it does not synthesize audio. Behaviour: local stdio only, with no network, authentication, credentials, or external service; a successful call appends a content-minimal hash receipt. Returns an object with voices, receipt_id, and receipt_head.
