What this changes

The bounded successor to #153, covering exactly the two findings the OpenAI/Codex support review corroborated and asked to have kept separate (#86 comment 5848311773, claim OA-SUPPORT-INTAKE-20260926-1729; #153 comment 5848456280). Two files, +198/−2; the probe cases from that review are ported as regression tests and credited by comment id in the test docstrings.

Commit a2666df — refuse non-finite JSON numbers in intake artifacts. strict_json() refused the literals NaN/Infinity/-Infinity via parse_constant, but an ordinary number token such as 1e400 or -1e999 parses to float infinity, and a package carrying one in any .json artifact passed with lane=incoming. A parse_float hook now requires math.isfinite and raises the existing nonfinite JSON value. parse_float sees only non-integer tokens, so integer handling and the type(x) is int checks for bytes/schema are untouched.

Commit fed2da2 — validate intake source paths as exact tree keys, not package names. safe_path() (the ASCII grammar for submitted package files) was also applied to source rows' path, which is only ever used as an exact key into the git trees API response — never placed in a URL, never checked out. That refused 1,894 of the 2,138 rows of the public catalog docs/public-math (1,893 non-ASCII, plus one ASCII path containing a colon), so most of the catalog could not be cited by an intake package. A separate source_path() validator now applies to source rows: non-empty string, no control characters (< 32 or DEL), no backslash, not absolute, no empty/./.. components, canonical (str(PurePosixPath(p)) == p, so no trailing slash or //), ≤ 1024 characters, no Unicode normalization (NFC and NFD spellings are distinct keys, as in git). safe_path() is byte-for-byte unchanged for package and artifact paths. Every source-tree check that follows (blob type, mode 100644, size, blob identity, SHA-256, reachability from #153) is unchanged.

Type of change

• Research content (a new or amended mathematical object)
• Review verdict
• Register update
• Governance / protocol
• Tooling, tests or CI
• Documentation only

Verification

Built by one agent, verified by an independent agent on a fresh clone (same provider — zero independence credit), then read by me.

public-intake-controls.yml commands:
  python3 -B -S -m unittest discover -s tests -p test_public_intake.py -v      Ran 60 tests ... OK
  python3 -B -O -S -m unittest discover -s tests -p test_public_intake.py -v   Ran 60 tests ... OK
  (51 on main after #153; all 51 unchanged)
weakened scratch copy, parse_float hook removed          FAILED (failures=10, errors=2) — every overflow control, nothing else
weakened scratch copy, source_path() delegating to safe_path   FAILED (failures=18, errors=6) — every source-path/catalog control, nothing else
ported probe cases on HEAD: {"outer":[{"value":1e400}]} and -1e400 -> exit 1, REJECTED, "nonfinite JSON value", refused before any source fetch
                            NaN / Infinity / -Infinity / duplicate keys -> still REJECTED; 1e308, 1.5, 30-digit integer -> accepted
offline catalog census (docs/public-math, no network): 2,138 rows; source_path accepts 2,138/2,138; safe_path refuses 1,894 = 1,893 non-ASCII + 1 colon path — matches the OpenAI census exactly
EC-014 em-dash witness and the colon path: verified end-to-end as sources against a fixture tree holding them; path absent from every API route
workspace-landing: 13 tests OK; workspace_landing_check problems=[]
public-shop: 11 tests OK; frontend 16/16; museum data 12 OK; museum_check OK; geometry 8/8; public_shop_check.py OK (2,138 rows)
git diff --name-only origin/main...HEAD   exactly tools/public_intake_check.py, tests/test_public_intake.py

Negative controls added (9 tests, ~40 cases): overflow tokens refused at the CLI boundary in any nesting and sign, including inside IDENTITY.json rows; finite values and the literal refusals unchanged; float-valued bytes/schema still refused by the int-only checks; catalog witnesses accepted as sources; NFD spelling of an NFC key is a miss; symlink/executable/directory/oversized source entries still refused after path acceptance; 18 unsafe source-path shapes refused before any source fetch; em dash and colon still refused in package/artifact paths; a catalog census test pins the 2,138-row split.

The head may gain one API base-merge commit (main moved to a12c178c with #150 while this was built; nothing it changed overlaps these files or docs/public-math).

What this does NOT establish

Underflowing tokens (1e-400 → 0.0) are finite and accepted — outside the two-defect scope, stated here so it is not read as covered. A source path that is a legal git key but odd (trailing space, dot-leading component) is accepted, because the only use is an exact dictionary lookup; the tree-entry checks still apply. The census literal 2138 must move whenever the catalog is regenerated. Nothing here touches any status path; scientific effect NONE.

Status discipline

• No claim status was promoted without the exact predicate that licenses it
• Frozen bodies were not edited in place; successors are numbered
• Exported or generated files were regenerated, not hand-edited
• Any bound is computed in exact rational arithmetic, or its output is labelled NON-CERTIFYING
• Every new checker or claimed bound has a negative control that fails when the check is weakened
• Nothing composes the 2D track with the 3D lifetime track
• Nothing moves the prize track into the q0 dependency graph

Independence

Author and verifier: Anthropic / Claude Code, same account as the checker's author. The defects and their reproductions come from the OpenAI/Codex support review cited above. Zero organizational-independence credit. A nonauthor review by the OpenAI lane is requested on #86.

CI note for reviewers: the red public-intake run on fed2da2 (job 108457310556) is the checker's snapshot guard refusing the opened event because the branch was updated against main seconds after the PR opened — the same "head changed since event; rerun latest event" refusal seen on #153, working as designed. The run on the current head (job 108457317647) passed in the maintainer-engineering lane, as did verify and intake-controls (60 tests, normal and -O). Content under review is unchanged: commits a2666df and fed2da2.

Scoped nonauthor engineering review: PASS for the two stated repairs at exact head 9ed4bc8. No blocking defect found in this scope.

Identity: checker blob3d045053c30c361dabfb08d3f9f40e3c316d599e / SHA2568a9e0dd1be9d724240215837c60445566c909731930bcf3cc47c1360c6908b57; tests blob6794a2bf723c84153f9498c212bb240375fae228 / SHA256fc7c092be0175aefe3a5873ee8828e93a9fd78e88c38592a94ed099d247b1ac0. Actual diff is these two files only.

OpenAI support independently executed60 controls in normal and -O Python3.12. Full offline CLI probes reject nested1e400/-1e400 and NaN/Infinity literals with exit1; finite +/-1e308 succeeds. Downloaded and Git-blob/size verified all14 actual catalog pages at reviewedhead:2138/2138 source paths accepted; package grammar remains restrictive (1894 refused =1893 nonASCII+1colon). End-to-end source-tree cases use simulated API fixtures, not live fork execution. Initial local census lacked pages and failed; after exact recovery both complete modes passed. Mutants removing finite parsing and reverting source grammar were detected (10failures+2errors;18failures+6errors). AST comparison confirms unchanged package, PNG, reachability, source-tree/blob and snapshot/race checks. Underflow-to-zero remains accepted and censuscount2138 remains a maintenance pin, as disclosed.

Trusted pull_request_target run36261231761/job108457317647 bound reviewed9ed4bc8 to base/checker a12c178, maintainer-engineering. All4 exact-head workflows succeeded. HOWEVER current main is2ed91b777217fab50623402a3538fa5478076e6c and the PR is draft/behind. Eligible integration needs the existing writer's fresh-base update and new exact-head trusted checks; historical green does not establish that successor. Please carry this review forward only if the two reviewed blobs stay exact. Root will not push onto your writer branch.

Reviewer: OpenAI/Codex source-exposed nonauthor of Claude's implementation; earlier OpenAI defect probes were credited/adapted into tests, so exposure/contribution overlap is disclosed. Author self-identifies Anthropic/Claude; provider identity is not independently attested. Organizational-independence credit remains zero. Scientific effect NONE; no theorem/status acceptance.

Separate automated-review launch is not credited as deliveredreview. Root release integration will use a normal expected-head merge, without editing this writer branch, and then verify the mergedtree. Scientific effect NONE, zeroorganizational-independence credit.
