Bound the post-deadline settle wait.
host_probe_pack must wait for normal completion so the hook can finish logging before the caller forgets the probe turn. Bound that follow-up wait. If the hook returns an error or the settle window expires, keep the empty-pack timeout result instead of aborting the sweep. Abort an expired task before cleanup.

There was a problem hiding this comment.
On direct CortexDB runs with asynchronous extraction, pre_turn has only accepted the probe event when this forget runs, so a queued extraction can finish after the event is removed and leave derived probe data available to later probes or the synthesis phase. This is the same immediate-forget ordering for which docs/evals/openhuman-host.md:157-163 records a derived residual; drain/cancel enrichment or isolate probe writes before treating the question as removed.

There was a problem hiding this comment.
On scale runs against CortexDB, bulk writes use WriteOptions::accepted(), and list/rank readiness does not imply that extraction and enrichment have drained. This early-return path skips the inspector queue-drain below, forgets the source corpus, and snapshots usage immediately, so queued work can complete later, recreate derived data after cleanup, and make both per-scenario and run cost totals materially low; wait for or cancel the queue before cleanup/accounting.

If a recall implementation leaks a sibling or deleted item in RecallAnswer::citations but the answer model paraphrases it or declines to answer, this helper returns false even though the citation snippet exposes the sentinel. The pack and context checks use separate fetch paths, so they do not cover a recall-specific scoping bug; inspect both answer and every citation snippet.

There was a problem hiding this comment.
If tenant scoping is broken only in the export/list path, all sibling checks here still pass because the audit tests only pack, context, answer, and derived data before deletion; export_contains is invoked later only with the Acme filter. This lets the new safety report claim sibling isolation without testing one of the public channels it explicitly audits, so add a Globex export check before the forget.

There was a problem hiding this comment.
For users selecting the OpenHuman profile from this example's rustdoc, the new --date-hint flag is the only way to choose a dated hook, but the top-level flag list still says --host openhuman itself runs the dated pre-turn hook. That sends parity experiments down a different path than documented; update the module docs to say plain recall is the default and dated recall is opt-in.

Handle BulkDocuments in the scenario runner
Adding an enum variant requires every exhaustive match over Step to handle it. The diff adds this variant but does not show the corresponding runner update; an exhaustive match in the unchanged evaluation runner will fail to compile, while a wildcard arm would silently skip the scale fixture. Update the runner to generate and write count documents using scale_document before running the probes, and add an end-to-end test for that path.

Preserve the flush return type for existing callers
flush previously returned Result<usize, Error>, but this change returns Result<FlushReport, Error>. The existing main.rs caller still consumes the result as the old count, so the example no longer compiles (or otherwise cannot use the returned value as before). Update the caller together with this API change, or retain the old return type and expose the timing data through a separate API.

Reserve budget atomically before starting the run
Two concurrent MODELS=openrouter processes can both read the same usage and pass this check before either run incurs its cost. For example, with a $1 cap, $0.50 already spent, and a $0.50 reserve, both processes pass and can spend another $1.00 in total, exceeding the cap. The live-budget-start file only stores a baseline and does not provide locking or a shared reservation. Lock the check-and-reservation operation, or use an atomic reservation record that each run updates before proceeding.

Verify sibling data survives each destructive operation
The audit checks Globex only before mutating Acme. A backend that applies the Acme filter too broadly, or whose subtree erase removes sibling namespaces, can delete Globex and still pass every assertion because all post-operation checks query only Acme. Add sibling-channel checks after forget and after erase (and preferably verify sibling export/recall remains available) so the stated sibling-isolation guarantee is actually tested.

Handle logger installation failure
log::set_logger can fail when another global logger has already been installed, such as by an earlier initialization path in the evaluation process. In that case this function silently does nothing, and drain later produces an empty report with no indication that timing collection was disabled. Propagate or otherwise explicitly handle the installation error so callers cannot treat missing timings as a successful run.

Provide the configured date hint to dated recall
Selecting date_hint() always invokes the dated lifecycle hook with a future that resolves to None, so the hook never receives a date hint and cannot prioritize hits from the hinted day. Pass the scripted turn's actual date-resolution future/value into pre_turn_dated instead of an unconditional None.

Do not coalesce builds across pending ingestion jobs
This removes every duplicate BuildBeliefs request regardless of what jobs occur between the duplicates. For a sequence such as BuildBeliefs(scope), IngestBrain(document), BuildBeliefs(scope), the retained build runs before the document is ingested, so it cannot include that document's beliefs; the removed build was the one that would have observed it. Coalesce only adjacent duplicate builds, or otherwise retain a build after any intervening write to the same scope.

Coalesce duplicate build requests before returning
coalesce_builds still pushes every job into ready, even when the duplicate build was detected and skipped from builds, so this test receives two jobs and fails at the following length assertion. Fix the coalescing implementation so duplicate BuildBeliefs requests are omitted from the returned queue; changing the assertion would only hide the regression this test is intended to catch.

Lock the shared budget reservation across concurrent runs
Multiple processes can simultaneously read the same usage and start value, pass the check below, and launch live evaluations whose combined cost exceeds BUDGET_USD. The file initialization is also non-atomic, so concurrent first runs can race while creating the shared baseline. Serialize baseline creation and the usage check/reservation with an inter-process lock, and hold it until the run's budget has been reserved.

Preserve the final belief build after ingestion jobs
This drops every duplicate BuildBeliefs job after the first one while preserving the original queue order. When ingestion and build jobs are interleaved, the first build runs before later IngestBrain jobs, and the later build that would include those documents is discarded. The resulting synthesis can omit beliefs for documents written later in the scenario. Coalesce by retaining or moving the last build for each scope after all corresponding ingestion jobs, rather than dropping later jobs in place.

Summary
Continue #251 with a corrected OpenHuman eval mirror and broader benchmarks. The default host path now uses plain
pre_turn, resumed probes use the resumed hook, and dated recall is opt-in. Probe questions are removed after scoring, pending identical belief builds are coalesced, and timed-out work records its eventual completion time. The suite adds coding, task-drift, opt-in 200-turn compaction, seeded 100/1,000/10,000-document retrieval, and a synthetic sibling-tenant/deletion audit. Stage timings distinguish scope discovery from CortexDB recall-pack time.The reference engine now batches fingerprint checks for
store_many, avoiding quadratic setup cost in the 10,000-document sweep. The runner also has an optional $5 OpenRouter budget guard.Measured results
tool_heavy, three fresh databases: initial pack 3/6, 1/6, 4/6; synthesis pack 6/6 in each; synthesis model answer 5/6, 6/6, 6/6. Host timeout counts were 7/19, 10/19, 6/19. CortexDB model costs were $0.031, $0.025, $0.017. The formerjmillermiss appeared in all three synthesis packs.The full commands, limits, and historical comparison are in
