P2 Badge Mark TinyBox enforcement as still required

This present-tense claim implies that admitted sandbox plans are currently enforced at launch, but the module only produces and consumes plan artifacts: crates/tinysecurity-sandbox/README.md:26-30 and docs/specs/security-module.md:279-288 explicitly say that process launching and concrete confinement are not implemented and that a future launcher must perform the checks. An integrator relying on this summary could mistake successful planning for actual isolation, so this should say TinyBox must enforce the plan and the launcher integration should remain listed as open.

# TinySecurity roadmap

The current bootstrap PR implements conservative policy evaluation, ordered checks,
versioned wire contracts, SDK init/reinit and native loading. Publishing those
contracts/artifacts remains pending upstream review and release. It intentionally does
not close the security extraction tracker.

The [implementation plan](docs/plans/security-module.md) orders the remaining
work: full host policy/command parity, unified redaction, connection-pinned
egress, TinyBox sandbox planning, durable audit/approvals, optional Jev,
native conformance and release gates, reviewed policy expansion, crypto last.

Production OpenHuman callers move only after upstream capabilities are merged,
released and validated with published checksums and native latency budgets.
Tracked by [OpenHuman #7328](https://github.com/tinyhumansai/openhuman/issues/7328).

## Delivered

Policy evaluation and ordered checks, scoped and immutable path policies, redaction
(including the boot diagnostic floor, [ADR 0007](docs/adr/0007-boot-diagnostic-redaction-floor.md)),
scoped egress grants, durable exact approvals, optional judge scoring, sandbox
planning, audit, confidential device, secret, cipher, password, keyring and pairing
members, and a CI-enforced release latency budget ([performance](docs/performance.md)).
`max_cost_per_day_cents` was removed from the contract ([ADR 0006](docs/adr/0006-remove-max-cost-per-day.md)).

## Open

- Confidential delivery to an ordinary (non-native) admitted host callback, needed
for config-cipher plaintext delivery and pairing `Begin`/`Verify` (TinyBus gap).
- Native conformance on macOS and Windows runners for device and secret members.
- Fault-injection and timeout latching conformance in the SDK.
- Windows alias, ADS and device-path handling and rich shell grammar parity.
- Calls-per-turn measurement against a representative OpenHuman workload.

Host callers move to a member only after it is merged, released and validated with
published checksums and the native latency budget. See [MODULE.md](MODULE.md) for the
current surface.

The characterized host debug path over two checks was 35 us p50 / 63 us p99.
The native boundary is substantially slower in this debug workload. These
numbers do not establish release-build performance, or a product migration
budget. A provisional gate to measure before migration is <=1 ms p50 and
<=10 ms p99 per batched Check on the same supported native runner. That gate
must be agreed against a representative released-module workload and its
number of calls per turn before host callers move. Bootstrap remains
release-gated irrespective of this synthetic result.

Describe the release workload as interleaved calls.

The release table is labeled “same workload,” but docs/performance.md describes grouped calls: 500 Evaluate calls followed by 500 Check calls. benchmark instead interleaves one Evaluate call and one Check call in each iteration. This mismatch prevents exact reproduction of the documented measurements.

Suggested fix 
-The native verifier sends 500 sequential Evaluate calls (one pure diagnostic)
-and 500 Check calls (two checks, allow plus unconditional floor deny) through
-the real MemoryBus broker and dynamically loaded native module. Each sample
-uses exactly one bus call.

Review comment at @docs/performance.md around lines 28 - 34:
Update the release workload description in docs/performance.md to match
benchmark: describe 500 iterations, each calling Evaluate followed by Check,
rather than grouping all calls by method. Preserve the stated checks and
one-bus-call-per-sample detail.

Release is roughly 9x faster at p50 than the debug run above, so debug numbers
must not be used for budgeting.

The agreed budget per bus call on a supported native runner is p50 <= 1 ms and
p99 <= 10 ms for both Evaluate and Check, roughly 20x and 150x headroom over
