Write each reuse verdict where something actually reads it

[forrestlinfeng]

The problem, in one number

On this machine:

~/.evomap/evolution/root_events.jsonl      21822 lines

value.inject          1873    ← the injection half has recorded all along
value.reuse_hit          0
value.reuse_outcome      0    ← the return half never existed

Every verdict this plugin has produced went nowhere:

• the Proxy forwards /asset/reuse-result to the Hub, and the Hub has no such route — its OpenAPI describes 1353 paths, 407 under /a2a/, none of them this one. A live probe returns {"recorded": false, "reason": "hub 404"}.
• proxyDaemon has no ingestor, so nothing was written locally either. The value.reuse_hit write lives on the MCP tools path, which this plugin does not use.

The consumers were never missing

// evolver-core/src/algo/orchestrator.ts:114
const reuseCounts = opts.reuseOutcomes ? reuseCountsFromSummary(opts.reuseOutcomes) : new Map();
// → candidateAssembly's reuseSentiment: a soft re-order of future candidates

summarizeReuseOutcomes and pruneCandidates are written and correct, the actuator is wired, and EVOLVER_REUSE_SIGNAL defaults on. All of it reads local root events, not the Hub. It was simply starved.

What changes

Each verdict is written to both ledgers:

outcome	root event
success	value.reuse_hit — the $ rail
failed / mismatched / stale / unsafe	value.reuse_outcome — the keep/prune rail

That split is what the accounting expects; summarizeReuseOutcomes reads success from one and the negatives from the other.

A report counts as delivered when either ledger took it, so a Hub without the route no longer leaves an asset pending forever.

The first runtime dependency, and why it is not optional

@evomap/evolver-core pinned at 2.0.38.

Ingestor is the repository's single write entrypoint for root events, and EventStore — single-writer, file-locked, monotonic seq, fsync, schema-validated, 4096-byte lines — is deliberately not exported. Hand-rolling the append would forge the one thing that file guarantees.

Mitigations:

• imported lazily inside a catch, so an install that cannot resolve it degrades to the old behaviour instead of breaking a turn
• the ingestor is cached by path, not as a singleton, so it follows the home directory rather than pinning the first one it saw
• the koffi native dependency it lists is loaded lazily from benchmark/referenceNativeRuntime.ts, which this path never touches. events/ and ops/ never reference it, and the global install here does not have koffi at all and works — which matters, since the dsh profile sets allowBuilds: { koffi: false }

cycleId is dsh:<sessionId>. deriveReuseEntries drops any entry missing either audit anchor (assetId + cycleId), and a task id is neither.

Verification

Before wiring anything, end to end against the real environment:

Ingestor wrote value.reuse_outcome + value.reuse_hit
readEvents → summarizeReuseOutcomes → pruneCandidates: ["sha256:probe"]

Three tests. Neutering recordReuseLocally fails the one that matters. 92/92.
