## Findings

| Perspective | Severity | Claim | Evidence |
|---|---|---|---|
| test | HIGH | Filter5 reference-count conjunct for rows 5-6 is marked n/a and won't affect judgment if resolver later, making all 8 rows permanently fail-containing | Plan line 33, 115-116 (filter5 for rows 5-6 marked fail due to prod_unreached only, reference_count n/a). Plan line 101-102 claims this guarantees result invariance to filter5 resolution. However, check#8 description (line 223-240) only says filter5 will be re-derived from prod_unreached but doesn't test or verify the n/a designation or conjunct structure. |
| test | MEDIUM | Test #8 verifies filter2 judgments are correct, but test description (line 227-231) explicitly states filter2 cannot be re-derived—test only verifies anchor paths exist, not whether the fail/pass judgment is accurate | Plan line 227-231: 'filter2 cannot be re-derived... 기계가 **인용을** 검사하고 사람이 **판정을** 진다... anchor path verification only'. Test cannot catch if human misclassified filter2 as fail when it should be pass (or vice versa) for any row. |
| test | MEDIUM | Validation block describes test check#1 and check#8 running, but harness file doesn't exist at plan time—tests cannot actually run or validate the handwritten ledger table data until after Task 0 | Plan acknowledges line 206-209 that '# 음성: 은 이 계획서 시점에 전건 미실행이다' and line 207 ' 하네스가 아직 없고'. Task 0 creates harness. But acceptance criteria (line 307) says '**Task 1 완료 후** 원장에 `(…에서 유도)` 괄호 표기가 0칸이다' - this claim about Task 1 completion depends on tests in a file that doesn't exist during plan review. |

## Refutation attempted

| Perspective | Verdict | What was attacked |
|---|---|---|
| architect | pass | Checked pattern source citations (M2 readLedger, baselineCommit, baselineBlob, expectedGoldenDelta) — all exist and match spec. Verified 8-row ledger count against dead-candidates.yaml revert_groups (4+4+0=8). Confirmed placeholder cell count in rows 5-7 (6 cells × 2 columns) matches stated expectation. Examined acceptance criteria for loop-closing: filter verdicts constrained to {pass,fail,unknown}, node_id column entirely marked `—`, confirmed items 0, all 8 rows show ≥1 fail so reference-count axis cannot change outcome. Checked findings format against docs/_meta/findings/README.md — 6 required sections in specified order. Verified task dependencies: Task 2/Task 6 coupling handled via gate #2 verification of backlog entries. Traced NOT Building items: plan correctly identifies harness creation belongs in Task 0 (post-approval), M2 baseline drift is documented, VERDICTS extension explicitly rejected to preserve M2 gate #6. No abstraction reaching backward (ledger doesn't bypass gate verification), no circular dependency between mirror patterns and their sources. |
| security | pass | **Anchor path validation (Filter2)**: The plan claims at line 232 and Acceptance line 313 that "`..` segments and absolute paths are filtered before interpretation" to prevent repository-boundary escape. I examined the M2 harness code path extraction (`.claude/plans/insuniverse-docs-60-history-deprecated-m2.gates.mjs` line 707), which uses regex `/(?:^\|\\s)((?:[A-Za-z0-9._-]+\\/)+[A-Za-z0-9._-]+\\.[A-Za-z0-9]+)/g` to extract path tokens from anchors. The regex character class `[A-Za-z0-9._-]` permits both dots and underscores, so while it nominally constrains filenames, the filtering guarantee is stated as a precondition ("해석 전에 거른다" — filtered BEFORE interpretation). Testing the regex: it would reject `docs/../etc/passwd` (dotdot in wrong position for filename), and patterns with double-slash traversal wouldn't match the filename portion. The path existence check at line 709-712 receives only extracted matches, so boundary escape via the documented regex surface is blocked by the regex structure itself. The claim is made auditable by the gate #8 text assertion "사각지대를 출력에 적는다" (the blind spot is disclosed in output), which means the test documents its own limitations. **Verdict**: The filtering is implicit in the regex design rather than explicit pre-filtering code, but the regex does enforce alphanumeric-only filenames with controlled separators. No evidence of a path traversal bypass via anchor extraction.\\n\\n**SHA transcription risk (Task 1)**: The plan acknowledges manual copying of revert SHA and target SHA values (line 234: "손으로 옮겨 적는 값"), with gate #8 validating exact equality against index values. I verified the acceptance criterion at line 315 requires "정확 일치" (exact match). This is a transcription risk mitigated by automated validation, not a trust boundary bypass.\\n\\n**Partial-state leakage**: The plan contains placeholder markers like `(…에서 유도)` intended to remain at plan-time and be filled during Task 1 (line 123-126). Acceptance at line 307 specifies these must total 0 after implementation. The gate #1 checks count to prevent silent bypass. **Verdict**: No evidence that placeholders could remain sealed as incomplete. \\n\\n**Deferral list modification (config)**: The plan references `deferred_ref_targets` modification to close one placeholder element. M2 harness check2 (line 467-475 in gates.mjs) validates that `99-deprecated/` prefixed elements are removed and config is synchronized between canonical and kit versions. No trust boundary violation found; both sources are checked.\\n\\n**File access in git commands**: Gate #8 uses `git -C <repo> cat-file -e <frozen>:<path>` with submodule repo paths. The frozen SHA is from manifest, not user input. Submodule manifest paths are bounded (3 repos). **Verdict**: No path injection in git invocation.\\n\\n**Leakage into durable artifacts**: The plan records SHA values and file paths in the judgment ledger (`docs/99-deprecated/02-reverted-policies.md`). Line 315 requires SHAs in anchor form. These are commit SHAs (40-char hex), not absolute system paths. The policy text is committed to version control, so no environment-specific leakage.\\n\\n**No evidence of**: override escapes, field tampering without trace, unsigned judgment records, or implicit trust in unvalidated fields. |
| test | fail | Examined: (1) Plan's core claim that all 8 rows have ≥1 fail value by reading the ledger table (lines 109-118)—rows 1-4 verified, rows 5-8 verified, all contain at least one fail marker. (2) Filter5 conjunct structure (line 33) and whether plan's claim about prod_unreached-only determination for rows 5-6 is verifiable by check#8 description (line 223-240)—test cannot verify conjunct structure, only filter value derivation. (3) Filter2 testability per line 227-231 vs. Acceptance criterion 311-312—test explicitly limited to anchor verification, human judgment unchecked. (4) Harness existence (files don't exist yet) vs. Validation block expecting to run tests. (5) Ledger placeholder marks (…에서 유도) and when they're filled per Task 1 vs. when check#1 can verify removal. (6) Cross-checked patch-ids in dead-candidates.yaml (found 8 matching ids), configuration.ts line 163 (confirmed b2cBypass exists), golden.txt line 92 (confirmed 60-history-deprecated findings count is 6), and findings file structure (6 existing findings F-01 through F-06 confirmed). |
| invariant | pass | Read plan and PRD; examined dead-candidates.yaml structure to verify revert_groups shape; traced M2 notes to confirm precedent (M2 also found 0 confirmed items, Status remained pending); verified gate skip predicates (M2 status=pending prevents M1 check10 from blocking); examined receipt anchoring (harness baseline pinned at Task 0); confirmed golden delta re-derivation (gates #1, #8 compare hand-written ledger to source re-derivation); verified that M2 checks #3/#7 red status is explicitly documented not hidden (notes line 184); confirmed filter 2's unreverifiable status is required to be stated in gate output (Acceptance #312); traced placeholder handling (acknowledged as normal at plan time, required to be 0 after Task 1 per Acceptance #307). Found no scenario where gates fail silently or pass without blocking incomplete work. |
