Update the stale CI count comments.
The assertion now expects verified 25/25, but the comment at Lines 103-104 still says 10/10. The templates comment at Lines 114-116 still says 5/5 with 5 not applicable, while this workflow now asserts 12/12 with 16 not applicable. Update those comments so maintainers do not follow incorrect expectations.

Preserve spaces in the reported module path.
stdout.split() splits ctrlrun.__file__ on spaces. A valid --keep directory such as release checks causes seen[0] and seen[1] to contain partial path tokens, so the validation fails.
Split the two printed records by line.

Use the platform-specific virtual-environment executable.
Windows creates the interpreter under Scripts/python.exe, not bin/python. The script therefore fails before installing the first released wheel on Windows.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Exclude schemas newer than the current writer schema.
A reader-first rollout can add v8 to KNOWN_RECEIPT_SCHEMAS while RECEIPT_SCHEMA remains v7. This filter then treats v8 as an older schema. G31 fabricates a future-schema row and can report a false compatibility result.
Compare each schema number with the current schema number.

v0.11 item 4. Implements
SPEC-v0.11.md§6: one chain, five receipt schema versions, walked end to end. AddsG31and moves the guarantee catalogue toctrlrun.guarantees/v7, once, as the first of items 2 and 4 to land.No new field.
schemahas existed sinceSPEC-v0.3.md§12.2. What was never proved is thatverify_chainwalks a chain holding more than one of them, hash by hash, each row hashed by the rule its own version wrote. v0.10's release pass proved thev6/v7boundary against the released 0.9.0 and stopped there.The premise, proved against the released wheels
scripts/five_schema_chain.py, run on 2026-09-14 against this branch:Five
pip install ctrlrun==, five environments, one store. A fixture is this build's opinion of what 0.6 wrote; the wheel is what it wrote.0.10.0is on PyPI, uploaded 2026-09-14T12:42:03, so the chain is built from released artefacts end to end rather than stopping at 0.9.0.That run was wrong the first time, and the way it was wrong is the finding
Run as
PYTHONPATH=src python scripts/five_schema_chain.py, which is how anyone runs a script against an uninstalled checkout, the variable is inherited by every child. So each "released wheel" imported this build'ssrc/ctrlruninstead of the wheel just installed beside it. It printed:Ten receipts, a clean walk, and nothing under test. A run that checked nothing looked exactly like a pass, and only the schema count gave it away, which is the number the script exists to produce. The script now strips
PYTHONPATH,PYTHONHOMEandPYTHONSTARTUPfrom every child and asserts, per release, that the interpreter ran from that release's own environment and writes the schema this script claims it writes.G31, and why it can be graded without a network
SPEC-v0.7.md§6.11 madeto_dictrender under its own schema's label and key set, and made a stored receipt hash the document it was read from. So aReceiptcarryingctrlrun.receipt/v3serializes to v3's 26 keys and hashes to what 0.6 stored, through the same_document_hashevery version has used.It cannot go through
put_receipt, and that is correct. Every backend doesreplace(receipt, schema=RECEIPT_SCHEMA, ...): a writer writes under its own schema, so an older receipt cannot be forged through the public API. The first version of this scenario tried exactly that and G31's own control caught it, reportingit holds ['ctrlrun.receipt/v7']where it had asked for five. The chain is therefore presented as aChainSourceview, which is whatG11already does to alter a row.Two controls, neither decoration:
v7rows verify perfectly and prove nothing (SPEC-v0.4.md§2.2);seq, or "verified" is a count of the rows the walk bothered to read.--only G31and a full run agree; both reportPASS.The catalogue is not contiguous, deliberately
ctrlrun.guarantees/v6becomesv7.G28toG30andG32are not in it: §8 assigns ids in item order so that splitting the milestone renumbers nothing, and item 4 lands before items 2 and 3.test_the_guarantee_catalogue_is_contiguous_from_G1asserted contiguity and now cannot. It is narrowed rather than relaxed, because contiguity was never what the check was for: it was for a number nobody built. A hole is now allowed only if it is a number §8 names, each row saying which item owes it, and anything else is still red. The release item is where that list must be empty.What this moved that was not obvious
Adding one applicable guarantee moved every hardcoded count in the repository, including a shipped one:
.github/workflows/ci.yml, authority exampleverified 24/24verified 25/25.github/workflows/ci.yml, templates exampleverified 11/11verified 12/12T119's applicable countEach was pinned rather than derived, and each is left pinned: the claim under test is that the denominator moves with what was graded and not with the catalogue's size, and a derived number could not fail.
