## Findings

| Perspective | Severity | Claim | Evidence |
|---|---|---|---|
| test | CRITICAL | Validation checks #1-#11 comprehensively validate that the plan was implemented correctly | Lines 232-379 of plan show Validation block that runs all checks. However, checks #2-#11 all call `node "$G" check<N>` where `$G` is `.claude/plans/insuniverse-docs-60-history-deprecated-m1.gates.mjs`, which is a file to be created in Task 0. The plan provides only a description of what the harness should do (lines 142-149), but shows NO IMPLEMENTATION CODE for the harness. Without seeing the harness code, it's impossible to verify whether checks #1-#11 actually test what they claim to test. |
| test | HIGH | The plan's Acceptance criteria state that findings file `60-history-deprecated.md` will contain exactly observations G16 and G17 (line 431: '`findings/60-history-deprecated.md` 에 G16 · G17 두 관측이') | Lines 407, 431, and 252-262 show Check #1 should verify findings file. However, the plan only requires verify.sh to check that: (a) findings directory exists, (b) file count is correct (c) heading count is 2 (d) 6-item structure is correct. According to `docs/_meta/verify/golden.txt` line 1187: `fixtask.findings_headings 60-history-deprecated=2` — verify.sh only counts headings, not validates content. A file with 2 observations about DIFFERENT topics would also pass. The test is not falsifiable for the specific requirement that G16 and G17 are the observations. |
| test | MEDIUM | Task 5 must update PRD §Success Metrics to add specific corrections to the '정본 3자 정합' and '유예 원소 해소' metrics (lines 209, 97-103) | Acceptance criteria lines 430-431 mark these PRD updates as `(미검증)` — 'not verified by test'. The plan explicitly admits there is no machine test to verify Task 5 actually made these PRD updates. While the plan documents what SHOULD be updated (lines 97-103), the validation doesn't actually check whether these specific updates occurred, only that the PRD §Success Metrics section exists. |
| test | MEDIUM | Check #3 baseline commit rule (line 280: `git log --diff-filter=A --format=%H -- $G` returns exactly 1 commit) is robustly defensible | The plan documents the rule and expected outcomes, BUT this rule depends on specific commit history that may not exist until Task 0 is completed. If developers must retry Task 0 or if there are corrections, subsequent --diff-filter=A queries could return different commits. The rule is sensitive to history edits. The plan notes in Risks section (lines 396, 399) that this is '우회 가능한 잔여' (bypassable residue) since there's no CI/protected refs, but doesn't test whether the baseline actually meets the 'one commit with harness only' requirement before tests run. |
| test | MEDIUM | The Validation section can run after Tasks complete and verify all requirements were met | Temporal dependency issue: Check #1 calls `bash docs/_meta/verify/verify.sh --check --bootstrap` (line 259) expecting certain strings in stderr. The plan claims (§GROUND G2 line 14) this passed on 2026-08-24. But the Validation block assumes verify.sh's output format is stable. If verify.sh is later modified (to add/remove output strings), the Validation would fail even if nothing changed in this plan's scope. The test is coupled to an external script's output format without documenting what format is required. |

## Refutation attempted

| Perspective | Verdict | What was attacked |
|---|---|---|
| architect | pass | Verified all plan citations (ownership.md schema 6-column structure, PRD Scope MVP fence defining 7 paths vs current 5-path tree). Traced abstraction integrity of 3-stage tree-editing path split across Task 2 and Task 5 — intermediate consistency verified before final freeze. Examined boundary enforcement: check4 avoids modifying archive fixtures, Task 1 delegation isolated to ownership.md. Analyzed baseline-commit anchor design for self-approval prevention — exact-match blob reading on --diff-filter=A prevents working-tree self-ratification; history-rewrite bypass acknowledged as unverified residual. Verified check#3/7 interdependencies use immutable baseline blobs, not current state. Checked for hidden reach-through coupling; found none — all cross-boundary claims have explicit ownership/gate tracking in NOT Building and Acceptance. Examined PRD Success Metrics redefinition in Task 5 — marked transparent, not hidden. All seams to M2/M6 explicitly documented in Open Questions and NOT Building with identified owners. |
| security | pass | Attacked on: (1) Self-referential harness verification (circular trust). Finding: Documented and explicitly marked (미검증) with residual risk noted in backlog. (2) Baseline commit anchor abuse — history rewrite. Finding: Same, acknowledged constraint due to lack of CI/protected refs. (3) Trust boundary violations through PRD path manipulation. Finding: PRD blob read from commit object, git-safe relative paths, no traversal patterns. (4) Temp file leakage (mktemp -d). Finding: Cleaned with trap, not leaked into artifacts. (5) Privilege escalation through findings file creation. Finding: Metadata only, not control-flow. (6) Path injection through file contents. Finding: All path handling through git/find commands, safe on Windows and Unix. (7) Secrets or absolute paths in durable artifacts. Finding: None found; only structural hashes and relative paths. (8) Golden file tampering. Finding: Compared against baseline commit blob, hash verification against expected set. Plan went through 4 rounds of Codex adversarial review absorbing 13 HIGH findings; all resolved. |
| test | fail | Examined all 11 checks in Validation section; traced acceptance criteria to test implementations; verified path existence for key files (verify.sh, golden.txt, PRD); searched for test content validation logic; analyzed whether Validation can actually execute given Task dependencies. |
| invariant | pass | Attacked: (1) baseline commit detection (diff-filter=A anchor, amendment resistance, history rewrite) — fail-closed with documented residual. (2) gate skip predicates (check #11 text-only verification) — acceptable cross-milestone delegation. (3) golden digest coverage (tracked keys vs ownership.md direct checks) — sound separation. (4) deferred ref terminus (check #6 bidirectional probe showing gate, not contract, is blocked) — user decision documented. (5) task ordering (consolidation of tree+golden edits, check-all after --update) — correct. (6) unknown input handling (no silent passes, exit 1 on absent) — fail-closed uniformly. No HIGH/CRITICAL invariant erosion found. |
