# Required CI runtime evidence
|
||
|
||
This record is populated from the consolidated `CI / required` Gitea job. A
|
||
qualifying sample consists of one deliberate cold native/dependency cache run
|
||
and four normal warm-cache runs on `aarch64-unknown-linux-gnu`. Each uploaded
|
||
`required-gate.json` contains per-stage elapsed time, Rust host/target, separate
|
||
compiled-Cargo, dependency-download, native, and tool cache hit state,
|
||
available peak-memory evidence, and the Skia binary outcome.
|
||
|
||
The compiled target key includes Rust 1.97.1, the ARM64 GNU target, every Cargo
|
||
manifest, `Cargo.lock`, required feature/policy configuration, and native
|
||
installer inputs. CI-driver-only changes reuse the newest generation through a
|
||
same-filesystem hard-link migration; Cargo still validates every fingerprint.
|
||
To invalidate compiled artifacts, change a keyed build input. A deliberate
|
||
`cold_cache` dispatch removes registry archives/index data, Git database data,
|
||
pinned audit tools, OpenJPEG, and Skia. It retains immutable extracted registry
|
||
sources and the compiled target so the cold dependency/native measurement does
|
||
not manufacture source-mtime rebuilds unrelated to cache correctness.
|
||
|
||
The pre-consolidation Gitea baseline was 13 automatic workflows and 333 runs.
|
||
Successful maxima included 22.9 minutes for the native workspace, 32.0 minutes
|
||
for Skia, 66.6 minutes for artifact audit, and 86.0 minutes for the release
|
||
matrix. Native code generation had a 13.2-minute median and 18.5-minute maximum;
|
||
even this one concern could exceed the new complete-gate budget.

The uploaded evidence reports the following internal gate timings. Warm values
|
||
are the observed minimum and maximum across the four warm runs.

All five consecutive runs used commit `05af8d5edf566fb79770990153d8561a98718ec4`
|
||
on the ARM64 `ubuntu-latest` runner. The 4:24 maximum leaves 10:36 of headroom
|
||
under the 15-minute job timeout. Branch protection for `main` enables status
|
||
checks with `CI / required (push)` as its only required context; direct-push
|
||
behavior is unchanged. Every evidence record reports `aarch64` with Rust
|
||
host/target `aarch64-unknown-linux-gnu`; observed peak cgroup memory is
|
||
264,696–264,712 KiB. Every Skia proof installed the pinned archive with SHA-256
|
||
`dd127f458a5e67a79f3936a8aa19f822fe90a1d6a11b50b5f84df2b0519d909c`
|
||
and records that no source build started.
