firecracker status(): open /dev/kvm O_RDWR; check kernel, dropbear, mke2fs

Two reviewer findings addressed:

1. _kvm_accessible() now opens /dev/kvm with O_RDWR|O_CLOEXEC instead
   of read-only. VM creation requires write access; a read-only
   descriptor can satisfy KVM_GET_API_VERSION but fails at boot time.

2. status() now checks every hard prerequisite that require_firecracker()
   checks at launch: guest kernel image, static dropbear binary, and
   mke2fs. Previously a host with a configured TAP pool but missing
   artifacts could pass status() and then fail during launch.

Regression coverage: TestFirecrackerKvmCheck gains test_kvm_open_rdwr_fails;
TestFirecrackerArtifactCheck covers each missing artifact; existing
TestFirecrackerStatus fixtures updated to stub the new checks.

+# PRD prd-new: Encrypted at-rest egress secrets (SecretProvider, interim slice)
+
+- **Status:** Draft
+- **Author:** didericis
+- **Created:** 2026-07-21
+- **Issue:** #355
+
+## Summary
+
+An interim step toward the generic `SecretProvider` (#355) that stops short
+of per-request minting. Today the orchestrator holds each bottle's egress
+auth tokens **in process memory only**, so any infra-container recreation
+silently strips every already-running bottle of its upstream credentials.
+This PRD makes those secrets survive a gateway restart by persisting them
+**encrypted**, under a key that is not itself sitting next to the
+ciphertext.
+
+The end state in #355 — short-lived, scoped credentials minted per request
+— removes the need to store anything durable at all. That is a larger
+change gated on per-upstream minting support. This slice buys back
+restart-survivability now without regressing to plaintext secrets at rest.
+
+## Problem
+
+`Orchestrator._tokens` (`bot_bottle/orchestrator/service.py:74-79`) is a
+plain in-memory dict, deliberately never written to the registry DB:
+
+> Held **in memory only** — never written to the registry DB — so the
+> gateway can inject each bottle's upstream credential without secrets at
+> rest. Lost on restart (re-launch re-registers them); the future
+> SecretProvider (#355) replaces this with per-request minting.
+
+The registry itself *is* durable (SQLite on a container-only volume), and
+so is the gateway CA since #450 / `2cd44cf7`. The tokens are now the only
+piece of gateway state that does not survive a restart, which makes the
+failure mode both silent and confusing.
+
+### Observed failure
+
+Checking out a branch that touches `bot_bottle/**/*.py` changes
+`source_hash()` (`bot_bottle/orchestrator/lifecycle.py:88-99`).
+`MacosInfraService._source_current()`
+(`bot_bottle/backend/macos_container/infra.py:159-169`) sees the mismatch
+and `ensure_running()` force-removes and recreates the infra container
+(`infra.py:198-208`). The registry rows survive on the DB volume; the CA
+survives on its host bind-mount; `_tokens` comes back empty.
+
+Every already-running bottle then fails closed, mid-session, on its next
+outbound request:
+
+- `/resolve` succeeds — the bottle is still `active` in
+  `orchestrator_bottles` and its policy blob is served intact, including
+  `- host: "api.anthropic.com"` with `auth_scheme: Bearer` /
+  `token_env: EGRESS_TOKEN_0`.
+- `tokens_for()` returns `{}`, so the resolved env overlay has no
+  `EGRESS_TOKEN_0`.
+- `decide()` (`bot_bottle/egress_addon_core.py:644-652`) blocks with
+  `egress: route for 'api.anthropic.com' declared auth but env var
+  'EGRESS_TOKEN_0' is unset` — an 89-byte `403` on every request.
+
+Confirmed live on the macOS backend on 2026-07-21: two bottles running
+since 20:29/20:30 were still registered `active` with valid policy after
+the 23:05 infra recreation, and both took 89-byte `403`s from then on,
+while a bottle launched *after* the recreation egressed normally. The
+recovery today is to relaunch every affected bottle.
+
+Note this is a re-attachment blocker distinct from #443/#445 and from #450
+— the CA and the gateway address were both fine. It is specifically the
+credential wipe.
+
+## Goals / Success criteria
+
+1. A bottle's egress auth tokens survive infra-container recreation: an
+   already-running bottle keeps egressing across a gateway restart with no
+   relaunch and no operator action.
+2. Secrets are **never** at rest in plaintext, and never at rest next to a
+   key that trivially decrypts them.
+3. Compromise of the registry DB file alone does not yield usable
+   upstream credentials.
+4. The stored form is revocable and rotatable without relaunching bottles
+   that are not affected.
+5. When the retained bottle record reaches the lifecycle status `removed`,
+   its stored secrets are destroyed. Status/event persistence and the removal
+   transition land separately; this interim slice intentionally retains the
+   ciphertext across today's teardown/reconcile calls until that lifecycle is
+   available.
+6. Migration is transparent: existing bottles keep working, no manifest
+   changes required.
+
+## Non-goals
+
+- **Per-request minting** of short-lived scoped credentials. That is the
+  #355 end state; this PRD is explicitly the interim slice and should not
+  foreclose it.
+- Generalizing `DeployKeyProvisioner` into the full `SecretProvider` ABC,
+  or the manifest-level `{ provider: <name> }` reference surface.
+- User-extensible provider discovery (`~/.bot-bottle/contrib/<name>/`).
+- Changing the `/resolve` contract's shape (it already carries `tokens`).
+- Fixing the *trigger* — `source_hash` churn on branch switch. Recreating
+  infra is legitimate; it just must not cost running bottles their
+  credentials. A separate guard that refuses recreation while bottles are
+  active is complementary and out of scope here.
+
+## Design
+
+> **TODO (didericis):** the encryption flow goes here — key custody, where
+> the key material lives relative to the ciphertext, the wrap/unwrap path
+> at register and at `/resolve`, and what an attacker who holds only the
+> DB (or only the host, or only the infra container) can recover.
+
+Constraints the design has to satisfy, for reference while drafting:
+
+- The gateway's `PolicyResolver` needs the cleartext at request time, on
+  the data-plane path, so unwrap has to be cheap enough to sit in a
+  per-flow `/resolve` (or be cached in memory after first unwrap).
+- The infra container is recreated routinely and unattended. Anything
+  requiring an interactive unlock on every recreation defeats the goal.
+- The DB lives on a container-only volume that the host does not mount, so
+  host-side and guest-side components see different filesystems — that
+  asymmetry is available as a place to split custody.
+- The agent must never be able to reach the key material. It is a separate
+  container with no control-plane token, which is the existing boundary.
+
+## Open questions
+
+- Where does the unwrap key live, and what recreates/re-derives it when the
+  infra container is rebuilt?
+- Is the cleartext cached in memory after first unwrap, or unwrapped per
+  request? (Latency vs. exposure window.)
+- What is the rotation story — re-wrap in place, or force re-registration?
+- Does this land behind a flag, or replace `_tokens` outright?
