 Addendum (post-push, same pass): audit commit `4c66a83f7bafeb56…` pushed `97123a1..4c66a83` → `origin/main` (report + fresh off-LAN stamp; code untouched, the plan's mandated fix commit `08398267040a832bdec0910626423f0dbfeb0a7f` remains the code change under test, confirmed ancestor of `HEAD`). Post-push `git fetch` + full byte sweep re-run vs the new `origin/main`: origin blob == local == webroot md5, tracked **21/21 (3-way)** + gitignored `site/vision/*.jpeg` **13/13 (2-way)** = **34/34 match, 0 mismatch**; `HEAD` == `origin/main` (this addendum commit adds only report text — zero site-file delta, so the sweep carries over by construction).

+Determinism: `after18-couple-rows.json` **byte-identical** to the canonical `after-couple-rows.json` re-captured in the same session (md5 `129e2a45…` — same as passes 14/15/16/17); `after18-mixed-rows.json` byte-identical to `after15/16/17-mixed-rows.json` (md5 `96665bbf…`). Frame set: the `after18` couple run landed on the known chart-animation-phase frame `eec99021c08c…` 63,753 B (pass-11/13/14/15/16/17 variant) with DOM row JSON byte-identical to canonical, and the canonical `after` couple run **landed on the canonical frame on the first attempt** — 1280×900 50,314 B md5 `cbac51ed5089…`, byte-identical to the canonical renders of passes 1/8/9/10/11/12/13/14/15/16/17. Fresh PNGs IHDR-validated: `after18-couple-table.png` (1280×900 63,753 B, anim-phase frame) / `after18-mixed-table.png` (1280×900 64,537 B, md5 `222c81a1…` — byte-identical to `after14/17-mixed-table.png`) / `after-couple-table.png` (1280×900 50,314 B canonical) / `after-fire-step-390.png` 1170×2532 @3× 167,045 B (md5 `761e8055…`, stable). One new frame observation: the canonical `after-fire-table.png` this pass is 1280×900 **53,323 B** md5 `b4ed3a16…` (passes 12–17 recorded the 67,310 B `685fd711…` frame) — a chart-animation-phase snapshot variant of the same page; IHDR-valid, DOM row JSON canonical (`after-fire-rows.json` firstDraw 40 / firstGIS 65, `ROWSWEEP-OK`), so the evidence row set is unchanged. The `after18` tag by script design captures only the couple scenario (FIRE + mobile 390 run under the canonical `after` tag), hence no `after18-fire-*` files.
+
+Harness notes: Playwright runs with `TMPDIR=/home/ubuntu/projects/retire-planner/.pwtmp` (harness TMPDIR read-only; no site impact); ssh byte-check uses `-n`; this pass rebuilt the sweep + K-aware rowsweep + mixed probe under `.tmp/mathfix18/` (gitignored) — sweep file lists regenerated with `git ls-files` (21 tracked + 13 ignored, `diff`-proven byte-identical to the pass-17 lists); rowsweep copied from pass 17 with only the detail-block filename retargeted to `after17→after18`; all ran unmodified otherwise. `audit/math-fix/` is gitignored by design — artifacts are local evidence, referenced by path.
+
+No code change required — plan executed end-to-end; fix commit `0839826` at `origin/main` (ancestor of HEAD, confirmed via `git merge-base --is-ancestor`); all gates fresh this pass. Final: **MATH_FIX_DONE**.
