## Findings

| Perspective | Severity | Claim | Evidence |
|---|---|---|---|
| security | LOW | A decrypted payload can still be a ZIP bomb that exceljs inflates fully in memory. Capping spinCount and checking stream bounds does not limit the decompressed size, so one crafted file from an allowlist admin can exhaust process memory. | Plan Task 2 only says 'spinCount 를 관측값(100000) 이하' and 'E0819 스트림 범위 이탈'. §NOT Building: '업로드 크기 상한 · 요청 동시성 제한 — 기존 4경로도 multer 기본값'. Only authenticated allowlist admins can reach this (class-level guards at samsung-intake-admin.controller.ts:12-13), and the unencrypted ZIP path is the same exposure the existing upload routes already have. |
| security | LOW | The redact covers exactly one path, request.body.filePassword. A direct caller that sends the password under a different key, or nested inside the JSON body, is still logged in plaintext. This is the same gap already in the logger, not a new one, and the frontend is held to the filePassword multipart field by #9. | insuniverse-server/apps/api/src/pino.ts:15 'req.body = req.raw.body' with customAttributeKeys req:'request' (pino.ts:37). forbidNonWhitelisted rejects unknown fields with a 400, but the log binding is written when the request starts, before the pipe runs (observation 9). |
| test | MEDIUM | The plan says the two log defences are tested separately, but they are not. The pino.ts redact covers any `request.body.filePassword`, so the multipart log test passes even if the multipart field does reach the log. If pino-http or multer timing changes, no test turns red. | plan.md:296 '#5 기대' says 'multipart 부재와 JSON redact 는 따로 본다 — 한 겹이 사라져도 다른 it 이 남는다'. Task 3 (plan.md:177-180) adds the redact to `pinoHttpOptions` and has the log spec use that same `pinoHttpOptions`. The multipart test is gates.mjs:79. The redact probe is 관측 20 (plan.md:82). Risk row plan.md:378 says '#5 가 … 두 겹을 따로 보고'. |
| test | MEDIUM | No test covers the spinCount cap (reject anything above 100000), which is the plan's accepted DoS mitigation (F5 ACCEPT_NOW). An implementation that accepts spinCount up to 10,000,000 would pass every gate. | Task 2 (plan.md:159-161) says '관측값(100000) 이하 spinCount 뿐이다 — 표준 상한 1천만을 받으면 한 요청이 이벤트 루프를 10초 넘게 막는다'. None of the 11 xlsx test names in gates.mjs:61-72 mention spinCount. Acceptance (plan.md:391-395) has no spinCount line. Risk rows plan.md:383 and F5 (plan.md:489) rely on the cap as the mitigation. |
| test | LOW | The DIFAT test runs on a relocation the plan builds itself from the 12KB fixture. It is not an independently produced file, so a CFB-reading bug that the relocation code shares would still pass. The independent 16MB check was a single run during planning (disclosed). | plan.md:113-114 (NOT Building) says 'DIFAT 경로는 매 실행 합성 재배치 spec 으로 보고'. Acceptance plan.md:393 marks 'FAT 목록이 DIFAT 섹터로 넘어간 파일을 연다 — 게이트 #4' as machine-verified, with no note of the ceiling. The test is gates.mjs:68. |
| test | LOW | No test checks that the response echoes the intent, although the plan relies on it to re-confirm the chosen direction. A server that returns a fixed or wrong `intent` would pass #5, and the front end shows that value first. | Task 3 (plan.md:175) returns '{ intent, encrypted, … }'. Task 4 (plan.md:195) says '서버가 돌려준 의도를 맨 앞에'. The parse test names (gates.mjs:75-78) cover only validation, the missing file and password absence. |
| invariant | MEDIUM | #8 does not fix how many originals it expects. The plan and Acceptance say '원본 2건', but the spec only requires at least one .xlsx and the checker only requires a non-empty result list. If one original is missing or renamed away from .xlsx, #8 still goes green on one file. | .claude/plans/samsung-account-intake-m3.gates.mjs:119-120 `xlsx = names.filter(n => n.endsWith('.xlsx')); expect(xlsx.length).toBeGreaterThan(0)` and :291 `if (!Array.isArray(rows) \|\| !rows.length)`. Compare plan Acceptance: '원본 2건의 행 수 · 로그인아이디 digest · 비밀번호 있음 계수가 사용자 변환 TSV 와 같다 — 게이트 #8'. |
| invariant | MEDIUM | The only exemption in #7's credential-attachment check is a bare path match. The plan says #4 proves the file is synthetic, but #4 only checks it names, pass status and assertion counts, and #10 never checks the fixture. A real encrypted original copied to FIXTURE, with the matching it's expectations edited, would pass both #4 and #7. What is taken as proof can exist without the work. | gates.mjs:57 `const FIXTURE = '...samsung-intake-synthetic-encrypted.xlsx'`, :267 `.filter(p => CRED_RE.test(p) && p !== FIXTURE)`, :56 comment '합성임은 #4 가 로그인아이디 전건 대조로 본다'. Plan §Validation #4 says '단정 내용은 #10 이 본다', but COUNTERFACTUAL (gates.mjs:94-97) contains no fixture axis. There is no size or digest pin on the fixture. |
| invariant | LOW | #7 lists untracked files for both submodules but not for the parent repo. An xlsx/tsv/csv left untracked under the parent `.claude/` tree is caught by neither the scope check nor the credential check, which the plan says blocks '표와 무관하게'. Nothing is exposed until a human stages it, and after that point no gate runs again. | plan §Validation lines 314-322: parent inputs are only `git diff --cached ... $BASE` and `git diff ... HEAD`. There is no `git ls-files -o` for the parent, while the submodules get `$T/sn` and `$T/an`. |
| invariant | LOW | The rollback claim ('한 커밋 revert 로 돌아간다') is only asserted; no test pins it. The revert also removes the pino.ts redact line, which was added as the second layer of password masking. | plan Risks row '되돌림 경로 부재 \| 낮음 \| … 한 커밋 revert 로 돌아간다'. No gate checks it. |

## Refutation attempted

| Perspective | Verdict | What was attacked |
|---|---|---|
| architect | pass | I checked the citations that hold up the plan's structure. 1) fc-agency.service.ts:1718 is extractDataFromExcel and :1889 is isValidRow, so the "copy the row rules but not the throw" claim points at the right code. 2) agency-fc-admin.controller.ts:261 is FileInterceptor('file') and agencyFcApi.ts:331 is new FormData, so both mirrored patterns really exist. 3) samsung-intake-access.spec.ts:27 hard-codes the handler list as ['getSession'] (observation 11). Deriving the list from the prototype does close the gap where a new handler escapes the check. 4) pino.ts:9-40 sets customAttributeKeys req='request' and copies req.raw.body onto req.body, so redact path 'request.body.filePassword' hits the logged key. The completion log reuses the child logger bound at request start, so no second unredacted copy shows up. 5) Boundaries: the new xlsx module only takes a buffer and has no I/O. It throws BadRequestException itself, which follows the existing service habit, and the plan lists this under NOT Building. The DTO/controller/front split does not create new coupling or reach across layers. Row judgment (M4) and applying changes (M5) are clearly left out, and the rows[] return shape gives M4 a place to attach. I found no defect in abstraction, layering or seams that I could back with evidence. |
| security | pass | 1. Checked the redact path against pino.ts. customAttributeKeys maps req to 'request' and the serializer sets body, so 'request.body.filePassword' is the right path. 2. Searched for other code that logs the request body (filters, interceptors, main). Nothing found; the only other body reader is certify-rate-limit.guard.ts, which reads usrPhone. 3. Looked for ways the password leaks through validation errors. Default class-validator messages do not echo the value. The new error codes E0816-E0819 use static messages. 4. Checked the password gate #8 uses. It is kept in the shell only, and the gate leaves the originals spec, the copy files and $T behind neither in the repo nor on disk (trap cleanup). 5. Checked whether real originals could reach git history. #7 blocks xlsx files even when they are listed in the change table, and the one exemption is a fixed synthetic path whose content #4 compares against the full synthetic login IDs. 6. Checked auth bypass on the new handler. Guards are class-level, and the handler list is now derived from the prototype and proven by the #10 counterfactual. 7. Checked the KDF slowdown attack. spinCount is capped at 100000 and only one cipher/hash combination is accepted. 8. Checked crafted CFB input. Plan covers chain cycles, out-of-range sectors and a truncated buffer. Missing HMAC verification lets someone tamper with their own upload, which has no consequence beyond that upload. 9. Checked what the response exposes. It returns counts only. Could not build a path from a hostile input to a HIGH consequence. |
| test | pass | I read the whole plan and the gates.mjs sections for SPEC_GROUPS, spec-names and the counterfactual. Checks and results: 1) Counts. xlsx 11 = 11 test names. parse 7 + access 2 = 9 = the '#5 9건' in the plan. Both match. 2) Empty tests. The oracle requires numPassingAsserts >= 1 (gates.mjs:253-255). 3) Verifier counterfactual. The copy sets passwordOk=true. Stubbing the flag, leaving it unused, or mapping a ZIP failure to E0817 all leave the wrong-password test green, and #10 then fails (gates.mjs:345). So this check does tell a working verifier from a broken one. 4) moduleNameMapper escaping in the heredoc. It resolves to the intended regexes. 5) Gate order. #7 runs before the temporary spec and copy files from #8 and #10 are created, and trap cleans them up. 6) Log tests. The multipart test cannot tell the two defences apart because the redact masks it (finding 1). 7) Over-permissive direction. The spinCount cap and the echoed intent have no tests (findings 2 and 4). 8) DIFAT relocation. The fixture is hand-built (finding 3). I did not open the target submodule sources beyond the plan's citations. No HIGH or CRITICAL defect found. |
| invariant | pass | Read the full plan and gates.mjs, the access spec's imports, and the server jest.config. I tried to open each gate: - #1: the `[ ! -f $B ]` skip. baseline-report re-checks srv_base/adm_base, and tampering with baseline.json is disclosed in NOT Building. - #2, #3, #6: machine-not-run inputs (no summary line, rc≠0 with zero diagnostics, admin program never loaded) all FAIL. - #4, #5: missing spec file, suite dies before running, it with zero assertions. All FAIL. - #7: stale temp spec/counterfactual copies left by a SIGKILL are caught as out-of-table or dirty-tree changes, so that path fails closed. Also traced the index and working-tree diffs and the FIXTURE exemption. - #8: missing directory, unset password, it never runs, empty output. All FAIL except the unpinned count. - #10: anchor count ≠ 1 FAILs. The moduleNameMapper regexes survive heredoc escaping, the access spec imports './samsung-intake-admin.controller' so the mapping applies, and the copies do not match testMatch. - #11: NOT Building is matched by name. - Traced the everything-fails path (tool missing, report absent, process killed) and found no branch that ends green. No HIGH or CRITICAL found. |
