# Independent evidence audit — final amendment

Verdict: **SUFFICIENT for delivered S1 and P1 rows only**, including the supplementary plan-source pair. No correction or recapture required within this scope.

This standalone amendment concerns PR [#24611](https://git.cafe/pingdotgg/t3code/pulls/24611), head [43cb23920c](https://git.cafe/pingdotgg/t3code/commit/43cb23920cf601caaf146c75477abc5dfee95cb2), and supplements the [original independent pass-2 audit](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/4f5774c66c29ad40/audit-pass2.md). Reviewed the [final evidence index](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/cd15ff1ffb81a895/caller-evidence-index.md) from its local artifact. This round was evidence-only: no source or PR edits, live userdata access, browser interaction, app launch/stop, or delegation. Only this amendment was written and uploaded.

## Supplementary source-pair verification

Opened all four full-viewport images individually: plan-source-before.png, plan-source-after.png, plan-source-Diff0.png and plan-source-DiffT.png. Independently recomputed the image arithmetic from the original RGB arrays using Pillow/NumPy, without invoking the supplied diff.py:

- Both originals are 1440 × 1000.
- 1,947 viewport pixels have a nonzero channel difference; 1,609 have a channel difference greater than 16.
- Published Diff0 exactly equals absolute per-channel difference ×8, clipped to 255.
- Published DiffT exactly equals per-channel absolute difference >16 mapped to 255, otherwise zero.

These results exactly match the supplied metrics. The plan text and intact source emoji match visually. Differences are confined to the sidebar titles/rasterization (including the earlier S1 title), the earlier thread's relative age badge (1m → 2m), and the implementation dropdown focus outline. No source-plan caret difference is claimed or observed. The supporting source-pair verdict is **SUFFICIENT**.

## Final index accuracy and retained verdict

The final “What else changed” list is truthful within the inspected evidence and retained pass-2 findings. The source-pair metrics and focus-outline disclosure are accurate. The observed hostname fs-15 is visible in both originals. The index retains real base/head app provenance, discloses the deliberately unavailable text-generation model fixture, and distinguishes persisted client-produced titles from execution of the shared helper on the server. It does not claim fixes for separate server truncators. Successful ordinary automatic title generation is not established; an effect marked succeeded alone does not prove a model error. The fallback-label runtime branch remains distinct from retaining a seed after automatic title-generation failure.

Pass 2 already opened the ten prior captures, independently verified S1/P1 differences, and independently reproduced a real head-app UI send with an OK response and the correct persisted clean title. This amendment relies on that reproduction and does not repeat it. Its title-generation effect was still running at extraction: **do not describe that independent reproduction as all-effects-complete**.

Final S1/P1 verdict remains **SUFFICIENT only for the delivered local web composer seed/persistence and proposed-plan implementation-title rows**, for actual merge-base versus actual head as documented in pass 2. No unresolved row objection remains within that scope.

Unverified: native mobile (no tooling), native desktop (no native Electron session), multi-model send, attachment and fallback-label branches, other provider adapters, and remote/relay/tunnel. No broader surface coverage, grapheme-cluster preservation, or separate server-truncator fix is implied.
