Problem

validate_report originally searched one JSON serialization of the whole report. Wildcard copy-safety patterns could therefore combine words from different fields and reject responsible text that never made the prohibited claim.

The first repair bounded the wildcard with JSON quote/backslash delimiters. Fresh current-head review found the inverse defect: a newline or quoted phrase inside one legitimate report field is JSON-escaped, so the delimiter also let prohibited certainty or false-authority copy bypass the gate.

RED → causal repair

  • ac4feef03bb4dcf97f128a2a557131e644e88fa2 is the test-first semantic RED. It adds three contracts: a newline inside one certainty sentence must still be rejected; quoted text inside one false-authority sentence must still be rejected; separate fields must never combine into one claim. The production repair followed before hosted execution, so this is not claimed as hosted RED.
  • 6298e6b47958da5b5bcb273771bc2674671da87b removes JSON serialization from the safety-pattern boundary. ReportDocument.model_dump(..., exclude={"quality_notes"}) is traversed into reader-visible string values, and certainty/medical/false-authority patterns are evaluated per string. Sentence punctuation (.!?。!?) still terminates a wildcard; newlines and quotes inside the same field do not. Exact phrase and pillar checks use the same field inventory joined with a separator, so field boundaries remain explicit.

This preserves the original repair goal while closing the escaped-text bypass. quality_notes remains excluded because it is audit metadata that can quote rejected copy.

Current acceptance

Current exact head: 6298e6b47958da5b5bcb273771bc2674671da87b on protected-base snapshot main@8c6a2fa76af1cb7f6bb7f56ceb4e7ce92d2f7897.

Fresh exact-head CI 34872668297, Security Scan 34872668457, SAST Semgrep 34872668357, and CodeQL PR 34872668381 are queued. Predecessor test/check results do not transfer. The PR is therefore Draft and must remain unmerged until one unchanged exact head has terminal applicable checks, current review, and no valid unresolved finding.

No gate weakening, self-approval, force update, destructive rebase, no-op retrigger, or predecessor GREEN transfer is authorized.

`validate_report` searches one JSON serialization of the entire report, and
three of the safety patterns were written with `.*`. A wildcard against that
haystack reaches from a word in one section to a word in a different section
thousands of characters away, so the patterns reported claims nobody wrote.

Reproduced on the existing valid-report fixture:

- `반드시 그렇게 되는 것은 아니므로 실제 자료를 먼저 확인하십시오.` raises
  `event_certainty`. The wildcard walks forward to a `합니다` in another
  section. The gate rejects the most responsible sentence a fortune report
  can carry, which is the opposite of what it exists to do.
- `이 결과는 만세력 앱으로도 확인할 수 있습니다.` raises `false_authority`,
  because `근거` appears in a later section summary.

The cost is not cosmetic. `generate_report` answers a quality failure with one
editorial repair generation, then asserts again; a model that hedges a second
time, as a good one will, fails the customer's job outright.

The three wildcards become `[^"\\.!?]*`. Excluding the quote and the backslash
stops a match at the end of a JSON string value or at an escape such as `\n`,
so it can no longer cross fields. Excluding sentence terminators keeps the
claim and its object in one statement. Nothing else in the gate changes, and
the adjacent-alternation medical patterns were never affected.

Coverage of what the gate must still catch is explicit: single-sentence
`반드시 …발생합니다`, `…된다`, `만세력 앱…근거`, `AI가…보장`, and
`계산기…확정` all still raise, and those five cases passed before the fix as
well as after it.

@coderabbitai review

Please re-review exact current head 6298e6b47958da5b5bcb273771bc2674671da87b. Focus on the escaped-text bypass that motivated the descendant repair: claim patterns must never combine separate report fields, while quotes/newlines inside one field must not suppress a real certainty or false-authority match. Also verify quality_notes stays outside reader-visible safety scanning and that field traversal does not introduce new cross-field matches.

@seonghobae The returned inspection confirms the re-review result for commit 6298e6b47958da5b5bcb273771bc2674671da87b.

I found no issues in the requested areas.

  • _reader_texts excludes quality_notes before traversal.
  • _reader_texts returns each string leaf as a separate value.
  • validate_report searches each certainty, medical, and false-authority pattern against each value separately.
  • A claim pattern cannot combine text from different fields, list entries, or nested string values.
  • _WITHIN_ONE_SENTENCE permits quotes and newline characters within a value.
  • _WITHIN_ONE_SENTENCE stops at ., !, ?, 。, !, and ?.
  • tests/test_quality_pattern_scope.py verifies newline and quote cases, cross-field separation, and genuine single-string violations.
⚠️ Action not completed

Review rate limited.

Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.

The per-field evaluation added in ac4feef and 6298e6b is the better fix and is
kept as written. Two gates it broke are repaired forward rather than reverted.

`ruff check` failed with two RUF001 findings on the fullwidth `!` and `?` in
`_WITHIN_ONE_SENTENCE`. Those marks are deliberate: they are the sentence
terminators Korean and CJK copy actually uses, and dropping them would let a
claim match across a sentence boundary in exactly the text this product writes.
They stay, with a `noqa` that records why.

Branch coverage fell to 99.94% on `quality.py 72->66`, the false arc of
`elif isinstance(value, list)`. It was unreachable: `model_dump(mode="json")`
on `ReportDocument` yields only `str`, `dict`, and `list`, so nothing ever fell
past the third test. Making the walk total with an `else` removes the dead arc
and is also safer, because a field that later dumps as a non-string is now
scanned instead of silently skipped by the safety patterns.

Gates on this head: 262 passed, 1 deselected, 100% statement and branch
coverage, ruff, compileall, check_docs, and product_gap_audit all pass.

Two commits arrived on this branch from another session, and they broke both gates

ac4feef and 6298e6b replace my regex bounding with per-field evaluation: _reader_texts walks the model dump and each safety pattern is applied to one reader-visible string at a time. That is the better fix and I have kept it exactly as written. It is the approach I considered and set aside as too large for one change, and it removes the cross-field problem at the root rather than narrowing a window.

Verified on that head standalone, not only in combination:

gate result
ruff check . 2 errors
statement and branch coverage 99.94%

Both would have failed quality (3.11) and quality (3.12) once those jobs ran.

What was wrong and how it is repaired

RUF001, twice. The fullwidth ! and ? inside _WITHIN_ONE_SENTENCE are flagged as ambiguous unicode. They are deliberate. Korean and CJK copy uses those marks as sentence terminators, so removing them would let a claim match across a sentence boundary in precisely the text this product writes. They stay, with a noqa recording the reason.

Branch coverage, quality.py 72->66. That is the false arc of elif isinstance(value, list). It was unreachable: model_dump(mode="json") on ReportDocument produces only str, dict, and list, confirmed by walking a real report, so nothing ever fell past the third test. Making the walk total with an else removes the dead arc, and is also safer: a field that later dumps as a non-string is now scanned instead of being silently skipped by every safety pattern.

Nothing was reverted and nothing was force-pushed. b77c439 only adds what makes the existing delta pass.

Gates on the new head: 262 passed, 1 deselected, 100% statement and branch coverage, ruff check, compileall, check_docs over 19 documents, and product_gap_audit with zero gaps.

Coordination

If you are the session that pushed those two commits, this branch is yours to continue; I am not claiming it back. Please pull b77c439 before your next commit so the repair is not lost. If you would rather shape either fix differently, say so and I will leave it to you.

I found this while test-merging my eight open branches against each other, which is also how I found and corrected an unrelated formatting reflow I had left in #52.
