 Release qualification requires an owner-selected `LICENSE`, its explicit SPDX expression and `license-files = ["LICENSE"]` in `pyproject.toml`, and removal of the unresolved `LICENSE_STATUS.md` (its history remains in Git). Adding license text alongside a status that still prohibits publication does not pass the gate. The replay shell bootstraps the hash-pinned Python 3.10 TOML parser from `requirements-replay.txt`, then validates all source-derived core metadata and every optional release-manifest field before archived code runs. To call `tools/verify_replay_inputs.py` directly on Python 3.10, first install that requirements file with `uv pip install --python /path/to/python --no-deps --require-hashes -r requirements-replay.txt`.

@@ -87,3 +87,13 @@ The private replay input gate permits only the declared pure-Python wheel metada
 Full core metadata is derived from the bound `pyproject.toml`, including dependency and extra declarations, Python requirements and description. Complete release manifests are checked against source, commit time, the pinned builder runtime/compressor/toolchain, license and UCNS lock bytes, artifact hashes and fixed candidate/non-transfer dispositions. The builder and replay gate execute the Git-bound release-contract helper bytes directly, avoiding cached helper bytecode. Final license qualification also removes the unresolved status and records an explicit SPDX expression and sole LICENSE file. Ten formerly proxied argument-dependent operation effects are now unknown; only the three actually called structural readouts contribute measured omitted-operation effects.
 
 Release manifests reject duplicate JSON keys at every object depth. Licensed replay requires exactly the wheel, sdist, manifest and canonical SHA256SUMS bytes; private replay accepts exactly the wheel and sdist. The checksum file is recomputed during both input and final checks. Known structural observers remain boundary-relevant omissions even when their individual quotient effects have no measured mapping. The minimal-refinement search uses only the three actually invoked readouts and finds two singleton refinements; full declared-surface coverage remains hmmm.

+The owner instructed “epac is weak copyleft”. This is resolved as MPL-2.0 using
+the organization’s existing skill-lib/metapat/edcm convention, with the
+interpretation disclosed before execution. `docs/license-selection.json` binds
+the unmodified official license text. EPAC grants no upstream license rights
+and no scientific standing through this selection. Licensed CI uses managed
+CPython 3.11.15 and the pinned release builder for all matrix jobs; each runtime
+replays the resulting normalized wheel/sdist and preserves all four release
+assets. Independent acceptance compares every matrix asset to the same locally
+reproduced candidate before publication.
