+# graphql-core 3.2.12 Strix lock regeneration
+
+Date: 2026-09-01
+Repository: `ContextualWisdomLab/.github`
+Pull request: #1570
+Protected base: `5686de41660d51a7a7f22b8840dfa6ccfe5ff3f1`
+
+## Root cause
+
+The first #1570 head reused the reviewed `requirements-strix-ci-hashes.txt` blob from stale Dependabot PR #1515. The dependency version and hashes were valid, but copying the blob did not prove that the current protected-main inputs still reproduce the lock through this repository's declared `uv pip compile` contract.
+
+## Exact regeneration
+
+A temporary read-only pull-request workflow checked out exact head `a64a59a6c5aa37d615d17eecbea68bc186f03a24`, downloaded the repository-pinned `uv` archive, verified its SHA-256 digest, verified the exact executable version, and ran the command declared in `CLAUDE.md` and in the generated lock header:
+
+```text
+uv 0.12.1 (x86_64-unknown-linux-gnu)
+uv pip compile --generate-hashes --python-version 3.13 --python-platform x86_64-manylinux_2_28 --override requirements-strix-ci-overrides.txt --output-file requirements-strix-ci-hashes.txt requirements-strix-ci.txt
+```
+
+Tool archive SHA-256:
+
+```text
+90b2f223fb69d19db49e117da601f64978593417988530aa733d456141b4bcbb
+```
+
+Combined `requirements-strix-ci.txt` + `requirements-strix-ci-overrides.txt` input SHA-256:
+
+```text
+bac58f2e5a276b3f14834aef311f5579e8977809357306f86d2e037d53ee403a
+```
+
+Regenerated output SHA-256:
+
+```text
+e33fd915f346e4c14fe3f59d1faa848e73fcb38399bf69f86e30f88d7cde9020
+```
+
+The regenerated file was byte-identical to the pre-existing #1570 lock. Relative to the protected base, the complete lock delta is exactly:
