+## what already shipped (checked against the code, 2026-08-02)
+
+One month old and already wrong in ten places. Everything below is marked
+built after reading the code, not the board. Read the tiers underneath with this list in
+hand.
+
+Infra 1 and 2, the two the ranking says block every feature, are both done. sqlcipher
+at-rest ships as `Store.enc` plus `OpenEncrypted`, a tmpfs working copy re-encrypted on
+`Close`, keyed from `db_key_env` in `deploy/mavend.json`. mavweb and mavcaldav are no
+longer at zero coverage: seven test files under `cmd/mavweb`, including
+`credentials_test.go` and `passkey_prf_test.go`, and two under `cmd/mavcaldav`. Infra 3
+is stale in the other direction. There are still no systemd units, but the deploy is
+`deploy/ecosystem/docker-compose.yml`, not scripts and tmux.
+
+Doable tier, built: rule trace and explanation as `/trace` plus `internal/loop/explain.go`.
+Recurring reminders as the cron column, `NextFireTs` and `RescheduleReminder`
+(`internal/store/reminders.go:206`), so "fires once right now" is wrong. Stale-reminder
+burst collapse as `collapseReminders` (`internal/loop/gather.go:209`). Revert as
+`VoidLatestFact` (`internal/store/facts.go:300`). Digest mode as `internal/store/digest.go`.
+Testing infra as the simulator and the eval lab (V-284, V-278). Passkey persistence as the
+JSON-backed `credentialStore` in `cmd/mavweb/credentials.go`. Most integrations shipped as
+their own QA tasks (V-246 mail, V-256 smarthome, V-258 rss, V-259 crawler).
+
+Doable tier, still open: correx, systemd units, memory decay and duplicate detection
+(nothing in `internal/memory` touches it), backup automation, import and export, barge-in.
+
+Epic tier, unbuilt as ranked. `event.Bus` exists (`cmd/mavend/intake.go:57`) but it is the
+intake journal from V-283, not the rewrite of facts into projections that this tier means.

 ## infra — blocks everything below, in order
 
 1. **sqlcipher at-rest** — auth chapter (cold-start = layer-3, key-in-core-only) is fiction without it. plain sqlite on disk right now, anyone with disk access reads everything.
