 ### Fixed
 
+- Aligned every `github/codeql-action` `init`/`analyze`/`upload-sarif` pin to one immutable SHA (`5595ccaf912efad79be6eef63a5619ff05969be3`, v4.37.6) after the upload-sarif-only Dependabot bump left analyzers on 4.37.0/4.37.5 (CWE-829).
+- Materialized base Python locks only when every package line is an exact SHA-256 pin or a bounded relative `-r`/`--requirement` include. A lone `--require-hashes` directive, a dotted include such as `./lock.txt`, or `-r other-hashes.txt` no longer enters the trusted build context.
 - Parsed `opencode.jsonc` as JSONC (stripping `//` and `/* */` comments outside string literals) in the reasoning-effort guard and its contract tests, instead of raw `json.loads`, which rejected the file the moment it carried its first explanatory comment (added for the `contextual-orchestrator` provider block) with `Expecting property name enclosed in double quotes`. Comment markers inside string values, such as the `$schema` URL, are left untouched.
 - Download the pinned `uv` 0.12.1 exporter from the official GitHub Releases URL instead of `releases.astral.sh`, which now returns HTTP 403 and blocks org-wide OpenCode `coverage-evidence`. The SHA-256 pin is unchanged. The opener may follow one hop onto `release-assets.githubusercontent.com` or `objects.githubusercontent.com` and still rejects every other host, userinfo, non-HTTPS scheme, and nondefault port (ContextualWisdomLab/.github#1109).
 - Compared the trusted `uv` executable's post-install `--version` output against the real GitHub Releases build's full string, `uv 0.12.1 (x86_64-unknown-linux-gnu)`, instead of the bare `uv 0.12.1` the prior check required; the genuine release binary always prints the target triple, so every installation was failing the pin check immediately after the archive download itself was fixed (ContextualWisdomLab/.github#1109).

+## Incident and buyer impact
+
+Dependabot opened an `upload-sarif` 4.37.6 bump while `codeql-pr.yml`
+still ran `init`/`analyze` at 4.37.0 and `scheduled-security-scan.yml`
+ran them at 4.37.5. A green upload does not prove the analyzer executed
+the reviewed action.
+
+## Decision
+
+Pin every `github/codeql-action/{init,analyze,upload-sarif}` use to
+`5595ccaf912efad79be6eef63a5619ff05969be3` (v4.37.6). Contract tests
+reject per-file and org-wide splits.
+
+CWE-829 forbids including functionality from an untrusted or unreviewed
+control sphere (MITRE, 2026). A second SHA is a second control sphere.
