test(office): align Python support contract with PR matrix

[seonghobae]

Problem

Protected main@a40b9489665bed7d95af619a6079b9c51cab299a already contains the #401 queue-fan-out change: the Office job runs only Python 3.14 for pull_request, while protected pushes retain the advertised 3.11–3.14 matrix. The retained repository contract still parses only a literal static list and therefore no longer describes the live workflow it is supposed to police.

This is a test-contract repair for already-integrated workflow truth. It does not change .github/workflows/ci.yml, the supported Python range, package metadata, dependencies, Office runtime behavior, or release policy.

RED → GREEN

RED on protected main: office/tests/test_python_support_contract.py requires python-version: [..] and exact equality to all four supported minors, but the protected workflow now uses the event-dependent expression ${{ github.event_name == 'pull_request' && fromJSON('["3.14"]') || fromJSON('["3.11", "3.12", "3.13", "3.14"]') }}. The structural contract cannot parse that current authority.

Candidate GREEN 378e03078a90f18c48317673344e4f1adb11ec8f changes only the contract test. It requires the exact event-sensitive shape, pins pull-request admission to the newest supported minor, and independently pins protected-push coverage to the complete advertised 3.11–3.14 set. The runner-image and release-workflow contracts remain unchanged.

This delta was discovered while reviewing #403 and is split into this repository-contract owner lane so the collaboration PR can be evaluated relative to a narrow prerequisite rather than permanently owning unrelated Office CI semantics.

Ready status admits this complete candidate to independent review and exact-head Checks. Terminal applicable CI/security evidence and a qualifying independent current-head review remain merge gates, not prerequisites to review admission. No predecessor result, no-op retrigger, self-approval, force update, destructive rebase, or workflow-gate weakening is accepted.

Noema LLM review

The PR is test-only and closes the previously identified gap: the Python support contract now parses each complete fromJSON array with json.loads and compares exact tuples for both the pull_request and push branches of the CI matrix. The tightened regex at the changed lines is precisely scoped to the expected GitHub Actions ternary expression and fails loudly on structural deviations rather than silently passing. The exact tuple comparisons reject any extra, missing, or reordered version, including unsupported values such as 'latest'. Two distinct probes (regex-match robustness and exact-comparison semantics) were falsified, confirming no regression or residual correctness, security, maintainability, or behavioral issue.

Reviewed changed lines

• office/tests/test_python_support_contract.py:57 (RIGHT): The new regex pattern is explicitly anchored to the pull_request/push ternary with fromJSON('...') on both branches, using a negated single-quote class inside the captured brackets. This matches the expected workflow YAML where JSON strings are double-quoted, and any structural deviation causes the subsequent assert to fail loudly rather than allowing a false pass.
• office/tests/test_python_support_contract.py:61 (RIGHT): The generator tuple(json.loads(versions)) preserves every element and its order. The subsequent equality assertions against the exact supported-version tuples are length- and order-sensitive, so any extra value (e.g., 'latest'), missing version, or reordering fails. This directly closes the previously identified gap where regex-based extraction silently discarded non-version entries.

Adversarial validation

• office/tests/test_python_support_contract.py:57 (RIGHT) falsified: The new regex could fail to match realistic ci.yml expressions (e.g., differing whitespace or escaped quotes), causing matrix_match to be None and the assertion to fail prematurely. — The regex at line 57 (right) is r"python-version:\s*\$\{\{\s*github\.event_name\s*==\s*'pull_request'\s*&&\s*fromJSON\('(\[[^']+\])'\)\s*\|\|\s*fromJSON\('(\[[^']+\])'\)\s*\}\}". The \s* tokens absorb whitespace around tokens, and the negated single-quote class [^']+ forbids single quotes inside the captured JSON. Standard JSON in workflows uses double-quoted strings, so the capture remains valid JSON. A different expression structure would fail the assert matrix_match is not None, not silently pass.
• office/tests/test_python_support_contract.py:61 (RIGHT) falsified: The exact tuple comparison could accept an unsupported extra value because json.loads might return a structure that compares equal to the expected tuple (e.g., via type coercion), or could ignore order or missing entries. — Lines 61-64 (right) show tuple(json.loads(versions)) applied to each captured group, followed by assert pull_request_versions == (SUPPORTED_PYTHON_VERSIONS[-1],) and assert push_versions == SUPPORTED_PYTHON_VERSIONS. Tuple equality is length- and order-sensitive; an extra element like 'latest' makes the tuple longer, so the equality fails. json.loads also raises on malformed JSON, making failures explicit. The prior review thread confirmed this is the intended fix to close the silent-discarding gap.
• Residual risk: No residual risk identified. The changes are confined to test code, and the two adversarial probes (regex robustness and exact tuple comparison behavior) were falsified. The only hypothetical risk would be a future change to the workflow expression that introduces single quotes inside the JSON strings, but that would break the workflow itself and would be caught CI-side; the current contract is internally consistent.

Follow-up head 740ffb4f4f7669525ebd6bbc28964e0b59cc8df1 replaces the previous assertion, which was still a surface-syntax pin.

Why the previous revision was not the repair. It required the matrix to be written as the exact conditional \${{ github.event_name == 'pull_request' && fromJSON(...) || fromJSON(...) }} and reported assert None is not None for anything else. That is the same defect class this branch exists to fix: the test names the absence of a pattern rather than the drift of a value, so any legitimate reformatting of the workflow expression turns the required Office job red on every candidate head simultaneously, with a message that identifies neither the real contract nor the real change.

What replaces it. _office_matrix_python_versions resolves the declared value instead of matching its spelling: it reads the job's python-version entry, decodes every fromJSON payload the expression selects between, and falls back to decoding a literal YAML/JSON sequence. Each assertion then states a resolved obligation and fails with the observed value.

• no matrix entry may name an unsupported minor;
• the exhaustive set must equal SUPPORTED_PYTHON_VERSIONS in order;
• the pull-request set must include the newest supported minor.

Resolver exercised directly. Accepted, with resolved values shown:

declared form	resolves to
protected main's conditional	('3.14',), ('3.11','3.12','3.13','3.14')
the same conditional, reformatted whitespace	('3.13','3.14'), ('3.11','3.12','3.13','3.14')
older plain inline list	('3.11','3.12','3.13','3.14')

Rejected, each naming the observed value:

injected drift	failure
fromJSON('["latest"]')	unsupported ('latest',) in ('latest',)
minor dropped from exhaustive set	exhaustive set wrong: ('3.11','3.12','3.14')
pull-request set missing newest minor	PR set wrong: ('3.11',)
job declares no matrix	the office job declares no python-version matrix entry

Review comment on the previous revision is closed by this. Decoding the complete payload rather than extracting only 3.x-shaped substrings is what makes a stray latest a named failure instead of a silently dropped entry.

Verification. tests/test_python_support_contract.py: 4 tests passed. scripts/check_docstrings.py: 100%. The remainder of the Office suite needs the hash-locked Linux wheels from requirements-ci.txt and is left to CI; this file imports none of them.

The rule behind this change is recorded as a durable maintenance obligation in #411 so the next configuration contract test does not repeat it. Merge here remains gated on the required current-head review and scan verdicts; no bypass is requested.

[seonghobae]

Current-head revalidation (740ffb4): build-and-test, Office/Python 3.14, admissions, Semgrep, Scorecard, Trivy report, and coverage completed successfully. The same current-head check set still has failures in CodeQL compatibility (actions, javascript-typescript, python), noema-review, trivy-fs, and opencode-review. Prior Noema approval referenced predecessor 7a769c... and is not transferable; no merge or rerun is claimed until these exact-head failures are independently resolved. Product source remains unchanged because no actionable source failure is evidenced.

[seonghobae]

Correction to the failure classification for head 740ffb4:

Trivy job 101745530483 is a real vulnerability gate failure. At 2026-09-07T13:26:44Z the log reports one MEDIUM finding, GHSA-cp6q-959q-f8rh, package @tiptap/core in pnpm-lock.yaml, and exits 1. The later SARIF upload and cleanup messages are not the cause of that failure.

The Office/parser tests pass on this head, but the dependency vulnerability remains. The existing TipTap migration lanes (#399/#402) must provide the fix through the governed integration chain; retrying this unchanged vulnerable dependency set cannot resolve Trivy. The other failed review/CodeQL gates remain independently unresolved.

[seonghobae]

Successor integration trace (2026-09-08): exact #405 head 740ffb4f4f7669525ebd6bbc28964e0b59cc8df1 is an ancestor of #412 head f44b5889ded28ed1a5b55da9985b0fa73025b0a3. #412 preserves the Python resolved-matrix repair, adds the matching TypeScript repair and event-predicate regression, and passed repository CI 34184813711. Canonical combined dependency/security owner #402 now integrates that exact #412 head as the second parent of ordinary merge commit 6352283aca654fb5587d3f607e02a57bf6fbd7d9. No force/rebase or delta disposal occurred. #405 remains open until the new #402 exact-head CI/security generation is terminal; queued successor evidence is not passing and this comment does not transfer predecessor status.

[seonghobae]

Final successor carryover verification (2026-09-08): #402 exact head 6352283aca654fb5587d3f607e02a57bf6fbd7d9 still contains #412 exact head f44b5889ded28ed1a5b55da9985b0fa73025b0a3 as an ordinary merge parent, and #412 contains this exact #405 head 740ffb4f4f7669525ebd6bbc28964e0b59cc8df1. The integrated Python contract blob is 8943928c4908bd0d64de1271a82507cce4cbc9ac. #402 exact-head CI 34193697466, Security 34193697556, and SAST 34193697561 are terminal success; CodeQL 34193697465 remains queued and continues to block #402 merge. Closing this predecessor only because the complete valid delta and history are verified in open successor #402—not because this PR's stale Security/CodeQL failures are being treated as success.
