 Both mirror-removal RFCs retained it while explicitly deferring the decision this RFC now makes. The [boundary-mirror removal](../../implemented/simplification/2026-06-20-remove-agent-boundary-mirror-events.md) kept it as "a live control signal, not a boundary"; the [stream-chunk removal](../../implemented/simplification/2026-07-02-remove-stream-chunk-mirror.md) kept it as "a live control signal with no durable twin, retained (its fate is a separate future decision)". The second rationale does not survive the code: the durable twin is `steering/message`, appended immediately before the emit with the same payload. The mirrored-vs-live-only line the taxonomy actually draws puts it on the mirror side: `agent/queued` is genuinely live-only (it fires at enqueue time, before any durable event exists, and already carries a `steering: boolean` flag — cancelled queued work never enters the log), while `agent/steering` fires at the exact moment its durable twin lands, carrying nothing the log does not.
 
-Steering itself is busier than ever — the hook bridges' turn-continuation decisions inject their reasons through `inbox.steer()`, landing as durable `steering/message` events that the hook-matrix goldens pin — and every one of those consumers observes the durable event. Nothing observes the mirror.

+Three pieces of the `dsh-hook-protocol` contract miss the discipline the [subagent-observe-enrich RFC](../../implemented/feature/2026-06-30-subagent-observe-enrich.md) records — it dropped an `agentType` lifecycle field for lacking a consumer, and these fail the same test:
 
 1. **`HookDialect`'s `'native'` variant** (`packages/hooks/hook-protocol/src/types.ts`) has zero producers — the bridges stamp `'claude'` and `'codex'`; the only `'native'` constructor anywhere is the lib's own unit test. The field's own JSDoc defines `dialect` as "the bridge that ran it", and native is not a bridge: the [interception-seams RFC](../../implemented/feature/2026-06-30-interception-seams.md) records that native hooks are not a package and that "a native plugin can already use the typed Decisions" without the durable hook log, and the flagship native-plugin worked example asserts exactly that (no `hook/*` events at all).
 2. **`HookOutput.suppressOutput`** (same file) is parsed by the codec and discarded on every path: no bridge branch, no merge fold, no warn, no deferred-list row — uniquely among its parsed-but-unhonored siblings, each of which carries a stated deferral (`updatedInput` → a logged warn plus the [pre-tool-input-rewrite proposal](../feature/2026-06-30-pre-tool-input-rewrite.md); `systemMessage` → a logged warn plus a README deferred row; `continue`/`stopReason` → a `TODO(hook-continue-false)` anchor plus the `'stop'` decision record). Structurally there is nothing to suppress: hook stdout never enters any transcript (context flows only via `additionalContext`; the log records only `decision`/`stderrSummary`), so a hook author setting `suppressOutput: true` gets silent nothing with no warn.

 ## Why not keep them?
 
-The hook-protocol-lib RFC deliberately records "parses the full CC superset", and `'native'`/`suppressOutput` are days old — the strongest counterargument is that this re-litigates fresh decisions. But parsing a field whose value can never influence anything is not protocol faithfulness, it is a reader trap; and a dialect variant that the design's own thesis says will never be stamped is vocabulary without an interpreter — the exact bar the stack's own review enforced when it dropped `agentType`. Both return trivially with their first real producer (a transcript surface that has hook stdout to suppress; a native-provenance feature that logs hook events). On item 3, the lib RFC chose per-bridge explicitness over a parameterized engine — but that choice governed payload construction and Decision mapping; the semantics of the SHARED durable event are precisely the "primitives where duplication would actually be dangerous" that the same RFC assigns to the lib.
