First match wins, in order:
1. **`BLOCKED_INPUT`** — `missing`/`unreadable`/`stale`/`changing`/`contradictory`/invalid provenance in any group.
2. **`GUARD_AND_REPAIR`** — Sufficient groups+authoritative acceptance/product-behavior add/remove/meaning change.
3. **`FOLD`** — Sufficient groups+unchanged acceptance/product behavior + complete equivalent coverage.
<!-- END RESLICE ROUTES -->
No fourth route/severity ladder. Slice count, file count, complexity, effort, and AFK budget never select the Reslice route; AFK execution limits remain independent.
`BLOCKED_INPUT`:no planning writes;fields/order.Malformed proposal provenance or controlling-root reacquired-binding mismatch:
