# Task24 isolated operator-review preflight

**Verdict: PASS (disposable synthetic preflight only).** Overall release remains **NO-GO**.

A symlink-preserving, byte-identical copy of `dualcoachtest` was bind-mounted only
inside `bwrap --unshare-net`. Telegram used a PTB HTTP-boundary mock and the provider
used an OpenAI SDK `httpx.MockTransport`; no live Telegram or provider network request
was possible.

The real `TelegramAdapter` callback/text handlers exercised regenerate, edit, approve,
wrong-role, restart-before-send, explicit send, stale, duplicate, and restart-after-send.
The accepted edit creates an immutable child revision, so the run correctly produced two
child revisions and two review cards, with one terminal child card and exactly one
synthetic customer delivery receipt (`sent_audited`).

A confirmed owner-DM edit defect was fixed: text handling previously derived a missing
`message_thread_id` and failed strict topic delivery. It now uses the canonical operator
address (DM topic `0`) and publishes the accepted child through the durable card path.

- Customer sends: **1**
- Durable delivery receipts: **1** (`sent_audited`)
- Provider requests: **1** (mocked)
- Pre-send, wrong-role, stale, duplicate, and both restart duplicate sends: **0**
- Live profile tree: **2,711** entries, identical before/after digest
  `9f8ac5fac4b867b4a67b647eabfcd064f364f6838af693f1b70c75f8257aa129`

Focused pytest, Ruff, new-file Ty, scoped diff check, and reproducible wheel checks
passed. Source-wide Ty remains blocked by 246 existing diagnostics outside the changed
region; none was suppressed.

Run the sealed no-live preflight from one terminal with:

```bash
/home/cube/projects/richard/traning\ coach/.omo/evidence/dualcoach-task-24-operator-preflight.sh
```

See `dualcoach-task-24-evidence.json` for redacted counts, candidate hashes, durable-copy
hashes, and command results.

## Synthetic-only live terminal acceptance

**Verdict: PASS (Task24 synthetic rehearsal only).** The Owner explicitly sent approved
review card `156` (`c8eab7b6685c3c65`) once. It produced exactly one durable accepted
callback ingress and one `sent_audited` synthetic customer-DM receipt (provider message
`157`). The two earlier provider receipts are generation receipts; the explicit send added
no generation-provider call.

The sealed observer performed the one authorized post-send restart and found no duplicate
provider call, card, delivery record, or customer DM. A second bubblewrap, real-handler
terminal matrix replayed stale, repeated, and wrong-role callbacks against a copied sent
profile: zero provider requests, customer sends, and durable mutations. The live profile
was unchanged by that matrix.

The complete private terminal record is
`dualcoach-task-24-live-terminal-evidence.json`; its canonical no-op matrix is
`task24-terminal-noop-matrix.json`. Overall release remains **NO-GO** pending Task25
rollback/cleanup.
