# Host support and process-safety registry

Generated from `support/external-tools.toml` and `support/process-safety.toml`; do not edit this file directly.

## Pidfs host support

- Contract: `pidfs-process-identity-v1`
- Platform floor: `linux-x86_64` kernel `6.9` or newer
- Runtime refusal: `fail-before-generation`
- Unavailable verifier behavior: `skip`
- Smoke claim: `current-boot-smoke-only` cached only by `boot_id`
- Smoke bounds: one attempt per step, `5000` ms per step, `60000` ms total, `5000` ms cleanup
- Positive support: unavailable until IP-03 implements an exact running-build matcher and the smoke runner

The smoke steps are bounded observations and never qualify source or build provenance:

1. `linux-x86_64-kernel-floor`
1. `pidfd-operations`
1. `pidfs-magic`
1. `concurrent-same-process-identity`
1. `last-close-live-reopen-identity`
1. `simultaneous-process-distinct-inode`
1. `stale-handle-cannot-affect-live-peer`
1. `exit-reap-drop-all-later-process-non-reuse`

## Qualified kernel builds

| ID | Kind | Release | Source commit | Build image SHA-256 |
| --- | --- | --- | --- | --- |
| `upstream-linux-6.9.0-x86_64` | upstream | `6.9.0` | `a38297e3fb012ddfa7ce0321a7e5a8daeb1872b6` | `e85edb5da3dc18295f05baeb38ff019a6621c1cac2e6ac81b99e14450c72d7fc` |

## Process-safety audit

Policy `causal-child-acquisition-v1` pins 13 dependency source/version/feature/API-review records, generates compiler-resolved disallowed type/method lints, and registers `process-safety-baseline-exercised-paths` as V2 exercised-path tracing.

The dedicated `lazaret-process-broker` boundary is `unimplemented` and no lint exemption is authorized. Dynamic coverage is `registered-exercised-paths-only`; it does not claim unexercised-path coverage.

## Complete registered data

Every authoritative host-qualification and process-safety field is reproduced below so generated-view drift remains complete.
