Implement the command registry (Task 1.3) - #42
Conversation
createCommandRegistry({log, sink}) with last-wins registration,
entry-identity-guarded Disposable, never-throwing async execute (unknown
IDs and handler exceptions surface as HostErrors via the status sink),
and unfiltered list(). Adds HostError/HostLog/StatusSink to core/host
per design.md §4.1/§5.

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk:🟡 Moderate · up to The command registry adds failure reporting and promises that command execution never throws, but reporting callbacks can still cause execution to reject, leading callers to observe unexpected failures instead of a resolved result. Logged error records can also be changed after recording. These bounded correctness and observability issues should be addressed or explicitly accepted before merging.

In `@packages/core/src/commands/registry.ts`:
- Around line 46-108: Preserve the non-throwing contract of
createCommandRegistry’s execute: add a safe notification helper that guards
HostLog.append, StatusSink.error, and error-message stringification, then use it
for unknown commands and handler failures so execute always resolves undefined
after errors. Ensure Error.message getter failures are handled, and add tests
covering throwing sink, log, and message getter implementations.
- Around line 65-76: Validate command IDs in register before checking or
updating commands, enforcing the required namespace.verb format through a shared
validator and rejecting invalid IDs before storing them in the Map; add tests
covering invalid registration.
In `@packages/core/src/host/errors.ts`:
- Around line 50-52: Update entries() so it returns a snapshot rather than the
internal records array, cloning each HostLogEntry and its HostError to prevent
callers from mutating accumulated logs while preserving the append-only
contract.

- guard sink.error and log.append behind safe helpers and move Error.message access inside describeError's try, so execute keeps its never-throwing contract even when injected reporters fail - validate command IDs at registration against the namespace.verb form (Req 3.2) via a shared exported isValidCommandId; invalid IDs throw TypeError before touching the map - HostLog.entries now returns a cloned snapshot to keep the log append-only - tests for throwing sink/log, throwing message getter, invalid IDs, and the entries snapshot (24 tests total) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WELSsojQQL1cTAR5iUUsTK
