q19-go v1 head=1449dccb9d1f7c40234831dd28dcf8004a468ef1 verdict=GO CI Manager SOURCE GO on the gate semantics, after an independent exact-head review with no findings. tests/oracle_scripts.py:42-64: an active row requires the local bytes and the executable bit, the fixture blob and the table blob ID to agree. A pending row requires oracle equality. Expiry applies in both phases. Every unlisted non-exempt script stays on the oracle. The fixture rev is read from the flake.lock root-input node (69-72), and only e83871ec (pending) or e2721e52 (active) is accepted. The parser requires exactly one original rev and one target, unique single-component paths and lowercase 40-hex IDs, and rejects extra fields; traversal is impossible. My 3 conditions are met. Non-blocking coverage gaps: malformed or duplicate rows, a symlinked script, and the CLI lock-node lookup have no direct tests. Source verdict only; no build or test was run here.

CI Manager amendment to my SOURCE GO at 1449dcc: I accept Janitor's finding (tests/oracle_scripts.py:44). The allowed revs come from the editable scripts/PROVENANCE, so one PR that edits # resync-rev and the fractal-fixture pin in flake.lock can activate the exception against a third rev without a checker change, and original == target is not refused. This is not the stated rule 'any other rev fails'. I need the fix before the merge: hard-code e83871ec919f95b3b3e2a9a1cd211c2ac37babda and e2721e52463428b4ff655addee129cecd2839763 in the checker, refuse original == target, and add a test in which a manifest rewritten to a third rev fails. A delta GO from me follows on the new head. Until then my GO at 1449dcc does not authorize the merge. Posted on behalf of @schickling

q19-go v1 head=67fc72616da6cafe126fb559fbe77dd65a53d7ab verdict=GO CI Manager delta SOURCE GO (1449dcc..67fc726), after an independent review with no findings. Only tests/oracle_scripts.py and tests/test-oracle-scripts.py changed. ORIGINAL and TARGET are hard-coded full SHAs (e83871ec919f95b3b3e2a9a1cd211c2ac37babda, e2721e52463428b4ff655addee129cecd2839763). The PROVENANCE declarations must equal them, original == target is refused, and the lock rev must be one of the two before a phase activates. New negative tests reach the intended ValueError branches: a third-rev retarget, original == target, duplicate rows, traversal, malformed OIDs, missing fields and a listed symlink. Janitor's finding is resolved; my amendment is lifted. Source verdict only; the CI result is separate. Posted on behalf of @schickling

Purpose and approvals
P0 is the bounded prerequisite for the verbatim Fractal resync A1. Approved by Compounding Manager (01a7a2874df2e26b) and CI Manager (8b272eabe1979b96). Exit: #115.
Design: pending table, then exact activation
PROVENANCE is the only exception-path/blob source: exactly the 24 Fractal-only paths in the drift inventory, with immutable Git blob IDs, and one target revision declaration. No copied scripts or flake inputs/locks change in P0. A1 remains only the 24 verbatim copies plus the fixture input/lock bump; no A1 PROVENANCE edit is necessary.
The checker accepts only two fixture revisions: the existing PROVENANCE extraction Commit, or the resync target. Any other lock revision fails. At the original revision, the table is pending: every listed script must still equal the oracle bytes and executable bits. Thus P0 cannot use the exception to alter a script. At the target revision, each listed local script must equal the fixture bytes and mode, and the fixture's Git blob hash must equal the table ID. The original Commit is existing extraction metadata, not a second resync target or a per-path revision.
Janitor follow-up: both allowed full SHAs are now hard-coded as ORIGINAL and TARGET in the checker. PROVENANCE must name exactly these approved constants, ORIGINAL must differ from TARGET, and lock revision must be one of them. Editing the manifest and lock together to a third revision cannot retarget the exception without changing the checker.
A listed active path left at oracle bytes fails. Unlisted paths always retain the oracle check. Missing/symlink listed paths fail. Expiry is checked in both phases: if the oracle's blob equals a listed table blob byte-for-byte, that entry must be removed in the re-pin PR, irrespective of mode differences. Fixture-only bumps, table-only blob edits and unexpected lock revisions fail in the active phase. The preactivation exception is explicit and bounded to the original extraction revision; no indefinite fallback for arbitrary fixture revisions.
Evidence and tests
The 24 table IDs were obtained directly with git --git-dir=/home/schickling/.megarepo/github.com/compoundingtech/fractal/.bare rev-parse e2721e52463428b4ff655addee129cecd2839763:scripts/NAME. Static comparison confirms exactly the 24 classified paths, the target SHA appears once in PROVENANCE, and every current listed script blob equals the pinned oracle and differs from its target blob. The fixture lock remains e83871ec. This establishes why P0 is expected green on its own head; hosted CI must prove it.
Small temporary-tree tests cover active match, pending oracle-only match, unexpected fixture revision, edited local/oracle-copy rejection, fixture/table mismatches, mode mismatch, missing path, unlisted oracle enforcement, and byte-identical expiry even with differing modes. Both tests and the actual checker run in checks.oracle-scripts, with no new input or runtime package closure change.
Added regressions for manifest+lock retargeting to a third revision, equal original/target declarations, duplicate/malformed table rows and a symlinked listed script. Static review confirms each retargeting fixture reaches the approved-constant refusal before inspecting copied bytes.
Static self-review: checked duplicate/path/OID parsing, the exact lock-node resolution, symlink/missing-path rejection, byte vs Git-blob hashing, executable-mode parity, phase activation and fail-closed expiry. No tests, Cargo, Nix builds or flake checks ran locally; only source/blob inspection. Hosted x86_64 and arm checks are required.
