-`packages/ui/acp/src/index.ts` is a *namespace plugin*: it exports `name`, `inject`, `Config`, and `apply` as separate named exports — the same shape as every other plugin in the repo (`invariants`, `llm-deepseek`, `tool-bash`, `stdio-chat`, …).

 ## Executive summary
 
-The ACP example attempted to enable filesystem plugins conditionally with `disabled: !!js ...`, but Cordis evaluates JavaScript expressions only inside plugin `config`. The raw expression object was truthy, so the filesystem stack was always disabled. Snapshot refresh then accepted `UNKNOWN_TOOL` results as new goldens. The fix uses an explicit filesystem overlay and adds static-config and snapshot-result guards.

 Incident write-ups: a bug reached a place it shouldn't have (a real user, a merged PR, a release), and the interesting part is *why our process let it through*, not just the one-line fix.
 
-A post-mortem is NOT an [RFC](../rfc/README.md) (which records a deliberate design decision and its rejected alternatives, or proposes future work). It is a backward-looking record of a failure: what broke, the mechanism, why every safety net missed it, and the concrete guardrails added so the same class of bug fails loudly next time.

 Write one when a bug is **subtle** (the mechanism is non-obvious and a careful engineer would re-derive it the hard way), **systemic** (the reason it escaped is a gap in tests/tooling/conventions, not a one-off typo), and **costly to rediscover** (it cost real debugging time, and would cost it again). Link the guardrails (tests, AGENTS.md rules, ADRs) the post-mortem motivated.
