/**
 * The daemon's half of workflow discovery (DES-walkthrough-proof §4.13; WT-W4): the project-level
 * view the two discovery entries count over, built from records the daemon already keeps and handed
 * to the watch registry as its `discovery` source (the registry reads it on a cadence, with a
 * deadline; the checks in `src/watch/checks/discovery.ts` stay pure over the view).
 *
 * Per run of the project:
 *   - `human_added` — the catalog ids a PERSON put in the plan, from the run's `wicked.team.plan.*`
 *     bus rows ({@link humanAddedOf}): `plan.proposed{by:"human"}` steps the PA's proposal did not
 *     carry, floor-added never, `plan.revised` (pa_added / member_request) never, less any step an
 *     accepted override removed;
 *   - `walkthrough` — the newest `walkthrough_review` recorder's `WALKTHROUGH-SEAL … overall`, read
 *     from the unit's engine-captured output (what the recorder reported; discovery counts, it does
 *     not accept evidence, so the seal is not re-verified here — acceptance does that);
 *   - `test` — the QE verdict the acceptance gate attributes to the run (the same ledger read
 *     `GET /runs/:id/acceptance` makes), only for a run with a `test` step and a registered repo;
 *   - `launched_at` — the session's `created_at`, else the run's first recorded frame.
 *
 * A run whose event log cannot be read is counted `unreadable`, never treated as "no". Terminal runs
 * are cached for the daemon's life (their facts cannot change); live ones are re-read.
