 ### Added
 
+- **`capabilities.enumerate` — list the calling capsule's own held capability names.** Mirrors the Rust SDK's `capabilities::enumerate`. The list dual of `capabilities.check`: returns the capability categories declared in this capsule's `[capabilities]` manifest block (`host_process`, `net_connect`, `fs_read`, …) — the names, not the scoped arguments within them (allowlists, `host:port`, paths). Argument-free (the kernel already knows the caller) and infallible — an empty array is the valid "no capabilities" answer — so a reusable capsule can ground its behaviour in what it can actually do instead of hard-coding it, avoiding code-vs-manifest drift. Backed by unicity-astrid/wit#13's `astrid:sys/host.enumerate-capabilities`; contracts submodule bumped accordingly (the `astrid:contracts` events bundle is unchanged).
 - **`process` persistent-process tier — `spawnPersistent`, `PersistentProcess`, and `process.{attach, listProcesses, statusMany}`.** Mirrors the Rust SDK and the host `astrid:process@1.0.0` persistent tier: a background child that **outlives the pooled, stateless instance** that started it (unlike `BackgroundProcessHandle`, whose kernel resource is reaped on instance reset). `spawnPersistent(cmd, args, options)` takes the persistent knobs (`label`, `keepStdinOpen`, `overflow`, `logRingBytes`, `maxLifetimeMs`, `idleTimeoutMs`, `exitRetentionMs`, `limits`) and returns a `PersistentProcess` keyed by an opaque id. `PersistentProcess` exposes `status` / `readLogs` (drain) / `readSince` (non-draining cursor → byte-faithful `LogChunkResult`; start with `logCursorStart()`) / `writeStdin` / `closeStdin` / `signal` / `wait` (bounded) / `stop` (SIGTERM→grace→SIGKILL, frees the slot) / `release`. Persist `proc.id` (e.g. in KV) and `process.attach(id)` from a later invocation to reattach — `attach` is a thin id-wrapper, so it works without the host's deferred `attach` resource fn; the first id-keyed call validates ownership. `process.listProcesses` / `statusMany` enumerate the capsule+principal's persistent processes. New types: `PersistentProcessInfo`, `SpawnPersistentOptions`, `LogChunkResult`, `ResourceLimits`, `ProcessPhase`, `LogStream`, `LogCursor`, `OverflowPolicy`; `ProcessSignal` gains `"stop"` / `"cont"`. The host's `watch` / `unwatch` lifecycle-event channel and resource-limit enforcement are not yet wired (poll via `status` + bounded `wait`). Backed by unicity-astrid/wit#12; contracts submodule bumped to the merged `astrid:process@1.0.0` persistent tier (the `astrid:contracts` events bundle is unchanged).

+ * a secret (enforce-don't-conceal), so both are ungated.
  *
- * Fail-closed: returns `false` for unknown UUIDs, unknown capabilities, or
- * registry-unavailable conditions (the host returns `registry-unavailable`,
- * which `callHost` raises as a SysError — capsule code that wants to swallow
