{"type":"assistant_message","payload":{"text":"I read this as a definitive architecture decision - I’ll provide the selected workflow, durable lifecycle, recovery rules, migration, and release gates now.\n\n# DualCoach decision memo\n\n## Decision\n\nChoose:\n\n1. **Automatic asynchronous drafting after each eligible finalized check-in**\n2. **Separate `Approve` and `Send to customer` actions**\n\nThere is no normal-path `Generate` button and no `Approve and send` composite action.\n\nAutomatic drafting never implies approval or delivery. Customer transport remains impossible until a distinct durable operator approval exists for the exact latest draft revision.\n\n## Architecture boundary\n\n```text\nCanonical check-in EventStore\n  -> durable generation request\n  -> asynchronous Coach/Polish worker\n  -> immutable operator draft revision\n  -> Telegram review card\n  -> durable Approve\n  -> separate durable Send intent\n  -> reservation-first Telegram transport\n  -> provider receipt\n  -> sent audit\n```\n\nTelegram is a command and projection surface, not authoritative state. Use the existing private ledgers, append-only events, locks, and startup draining; do not add a broker or general workflow engine.\n\n## Viable alternatives considered\n\n### A. Automatic draft + separate Approve/Send — recommended\n\n- **Coupling:** Provider latency is removed from the check-in and operator callback paths.\n- **Testability:** Generation, approval, and transport faults can be injected independently.\n- **Migration:** Reuses the existing `nc2` created/edited/approved delivery lifecycle; adaptive composite actions must be retired.\n- **Failure mode:** Automatic generation may become blocked or backlogged, but the customer check-in remains safely saved and nothing is delivered.\n\n### B. Click-to-generate + Approve-and-send\n\n- **Benefit:** Fewer unused provider calls and fewer final operator clicks.\n- **Coupling:** A Telegram callback initiates provider work, while the final composite chains approval, activation, delivery enablement, provider I/O, receipt persistence, and publication.\n- **Failure mode:** This recreates the observed callback-timeout ambiguity, orphaned generation claims, and partial composite transitions. A failed callback can conceal a committed approval or provider attempt.\n- **Migration:** Closer to the current adaptive UI, but preserves two competing lifecycle models and is harder to prove safe.\n\nThe observed failures decide against B.\n\n## Durable state machine\n\nEach transition is append-only and idempotent by immutable check-in, revision, approval, and delivery identifiers.\n\n```text\nCHECKIN_FINALIZED\n  -> GENERATION_QUEUED\n  -> GENERATING\n  -> DRAFT_READY(revision N)\n  -> APPROVED(revision N)\n  -> DELIVERY_RESERVED\n  -> PROVIDER_IN_FLIGHT\n  -> RECEIPT_RECORDED\n  -> SENT_AUDITED\n```\n\nAlternate transitions:\n\n```text\nGENERATION_QUEUED/GENERATING\n  -> GENERATION_BLOCKED_AUTH\n  -> GENERATION_QUEUED after credential repair\n\nGENERATING\n  -> GENERATION_FAILED\n  -> GENERATION_QUEUED by Retry generation\n\nDRAFT_READY\n  -> SUPERSEDED + DRAFT_READY(revision N+1)       # edit\n  -> SUPERSEDED + GENERATION_QUEUED(revision N+1) # regenerate\n  -> HELD\n\nAPPROVED\n  -> SUPERSEDED + unapproved revision             # later edit/regenerate\n\nDELIVERY_RESERVED\n  -> APPROVED                                     # proven no provider invocation\n\nPROVIDER_IN_FLIGHT\n  -> DELIVERY_UNKNOWN                             # no durable receipt; terminal, no resend\n\nRECEIPT_RECORDED\n  -> AUDIT_PENDING                                # audit failure; reconcile only\n  -> SENT_AUDITED\n```\n\n### Invariants\n\n- One initial generation request per canonical finalized check-in event.\n- Safety-held, disabled, stale-consent, or ineligible check-ins create a hold notice, not a customer draft.\n- Approval binds operator identity, approval event, draft revision, body digest, source check-in, and current authority.\n- Editing or regenerating invalidates all prior approval and send capabilities.\n- Send requires the latest matching approval event.
