FI-FILBERT-5 — independent pattern/profile addendum verdict

Reviewer: filbert. Author/follow-up owner: darkwing. Date: 2026-09-06.

Admission and exact verdict

APPROVED for the written addendum only. The proposed separation preserves strict CLI admission while requiring genuine Node/Python schema agreement. It is not a whitelist or permission to waive the red differential gate.

No competing current personal owner-authorized assignment appeared. I did not author/co-author this proposal. This narrow review does not start or replace the later frozen implementation review.

Numbered findings and dispositions

1. Confirmed / no blocking defect — the mismatch premise is reproducible. For the pinned id, runtimeId and digest definitions, Python/jsonschema accepts a valid value followed by exactly one final LF, whereas the measured Node ECMAScript patterns reject it. Two final LF, CRLF, CR, interior LF, U+2028 and U+2029 did not share that acceptance. The proposal correctly requires independent outcomes instead of treating every line separator alike. No correction required.

2. Confirmed / no blocking defect — no weaker admitted identity grammar. Normative points 2–4 require strict whole-string matching for every occurrence of the affected types, including unselected records and declared wrapper inputs, before indexing or admission. Original strings are preserved; no trimming or newline-stripped identity can enter the graph. Thus reproducing the oracle's schema-only acceptance does not enlarge the CLI's accepted identifier language: the additional profile still rejects the final-LF cases with exit 2, invalid-request/profile-pattern-mismatch and safe pre-admission output. This fits the charter's existing schema/profile separation. No correction required.

3. Confirmed / no blocking defect — the proposed gate is not an oracle whitelist. Points 1,5,6 require an actual independent Node shape verdict, zero schema-column disagreements, independently asserted profile verdicts and real CLI refusals. They prohibit named exceptions, deleted witnesses, copied oracle answers, harness-only answer adjustment and test-only rejection wrappers. Green must mean schema agreement AND production profile enforcement, not relabelling an ongoing discrepancy. No correction required; code review must verify these obligations.

4. Confirmed / bounded scope — targeted profile, not blanket newline rejection. The proposal leaves legitimate free-form multiline text and existing path/time formats separate. I independently confirmed an escaped-newline mission objective remains valid under the pinned record schema. This supports the required negative control: an implementation that bans every decoded newline would violate this addendum. Pinned schemas/checker, dependencies, output fields and allowed source paths remain unchanged. No new runtime capability or grant is introduced.

5. Informational / unverified implementation gate — written approval does not turn the build green. I did not inspect the moving implementation, independently validate the reported 239-file manifest, identify/re-execute its four particular witnesses, or run its differential bridge/CLI. Those remain reported context, not my receipts. The new frozen code candidate must preserve those witnesses, pass every mandatory check, and receive full independent code review. No correction to the written proposal is required; no functional acceptance is issued here.

Independent measurements in this review cycle

1. sha256sum verified the exact addendum and unchanged charter hashes above.

2. Read records.schema.json using git show at d4696d09 and independently checked SHA-256 05774aaf6943cb69c113e39ff1c29676a2a230ca7bf665c50dbcaa8049672af6.

3. Inline Python using Python 3.12.8/jsonschema 4.26.0 validated three pinned type definitions over eight variants each. An inline Node v26.8.1 subprocess evaluated their actual ECMAScript patterns and a strict-end helper on the same original values. All 24 expected matrix rows asserted successfully; exit 0.

   Value variant, for each of id/runtimeId/digest	Python schema	Node pattern	Strict-end helper
   Valid value	true	true	true
   One final LF	true	false	false
   Two final LF	false	false	false
   CRLF	false	false	false
   CR	false	false	false
   U+2028	false	false	false
   U+2029	false	false	false
   Interior LF	false	false	false

   The helper is only a regex measurement, not the proposed schema compatibility implementation, profile traversal, differential bridge or CLI.

4. A separate in-memory mutation of the committed valid mission fixture inserted an escaped newline into its free-form objective. Pinned record-schema verdict true, assertion passed, exit 0. Custom path/calendar formats were not exercised by that unchanged-field shape probe.

No dependency installation, implementation edit, helper implementation file, staging, commit, push, native/sync/live runtime, credential read or ~/.mosaic work occurred. Calculations used synthetic strings and committed schemas in memory. Only this offered verdict path was written in the repository.

Return boundary

Approval permits treating this exact proposal as the reviewed written addendum, not treating Rocko's current red build as accepted. Coordinator instruction and deliberate binding of updated test identities remain necessary before code resumes. A green frozen implementation, independent CODE review and Jason's demo remain separate subsequent gates. Follow-up stays with darkwing; no automatic advancement.
