meta description -> locked (A3) auto-save string (history.html L6).
page-sub -> locked (A3) string, the <strong>Save</strong> emphasis retired with the button (L106-109).
empty row -> locked (A3) string; colspan=6, hidden, and row id untouched (L163).
h1, the anonymous gate section, and history.js are byte-identical — state language verified accurate.

+All verification is green. Final state check complete — no code changes were needed; this pass was pure verification.
+
+**Phase 65 — final verification pass (all tasks 01–05 already complete in `complete/`; commit `8a1f99c` landed)**
+
+- Verified implementation in code: `.chat-bottom` is the last child of `.chat-shell` wrapping `.chat-actions` (New chat → Share, ids/aria-labels intact) + `#composer`; `.chat-bottom` is `position: sticky; bottom: env(safe-area-inset-bottom, 0)` with no z-index (A1); `justify-content: flex-end` right-edge alignment (A2); ≤640px full-width vertical stack; `#composer` sticky declaration retained
+- Dedicated suite: `uv run pytest tests/e2e/test_bottom_chat_actions.py -v --no-cov` → 4 passed (pin across sticky range, resting bottom, settled above footer, A2 + DOM order, mobile stack, 360px overflow, 44px targets, New chat/Share click-through)
+- Regression E2E, each in isolation: pinned_composer 4 ✓, save_share_ux 5 ✓, chat_persistence 4 ✓, share_chat 4 ✓, chat_history 5 ✓, smoke 3 ✓
+- Full gate: `.agent/validate.sh` exit 0 — `uv run pytest --cov=app` 1251 unit+integration tests passed, coverage TOTAL 99% (>90%); `uv run ruff check .` clean; `uv run pyright` 0 errors
+- Criteria 1–7: all met (see above). Criterion 8: single `--no-gpg-sign` commit `8a1f99c` exists staging exactly `.agent/ frontend/ tests/` (no gpgsig; `commit.gpgsign=false`); the `00_phase.md` move to `complete/` is the harness pipeline step — left in `todo/` per instructions
+
+**Deviations / notes:** No defects found, zero code edits. `.agent/PLAN.md` is absent from the repo (referenced by AGENTS.md; pre-existing — the phase overview/task files served as the binding spec). Worktree carries only uncommitted `.agent/` bookkeeping (task-05 file move + reports) managed by the harness. Next pending phase: `66_history_auto_save_copy`.

+
+**Implemented**
+- `frontend/history.html`: replaced the three Save-button strings with the locked A3 auto-save copy — meta description, `.page-sub`, and the `#history-empty-row` cell (element, indentation, `colspan="6"`, `hidden` all preserved; markup otherwise byte-identical).
+- `tests/unit/test_history_page.py`: updated the phase-50 pin that asserted the retired empty-row copy to the locked A3 string (required to keep the suite green).
+
+**Verification**
+- `grep -c "pressed <strong>Save</strong>\|press <strong>Save</strong>\|every conversation you saved" frontend/history.html` → 0; each of the three A3 strings present exactly once.
+- h1, gate section, table caption, `history.js` byte-identical (git diff shows only the 3 HTML strings + the test pin; history.js md5 unchanged).
+- `uv run pytest --cov=app --cov-report=term-missing` → 1251 passed, TOTAL 99% (>90% gate).
+- `uv run ruff check .` → all checks passed; `uv run pyright` → 0 errors/warnings.
+- Remaining case-sensitive "Save" hits are only state strings ("Saved chats" h1/title/meta/caption/aria-label, "Saved conversations are admin-only"); no other page names a Save button (no follow-up material for the commit body).
+
+**Notes**
+- `.agent/PLAN.md` does not exist in this repo; the phase's `00_phase.md` carries the binding A3 copy, which was followed exactly.
+- Working tree also contains harness-side phase-65 move/report artifacts (pre-existing, untouched).
+
+**Next pending task:** `.agent/phases/todo/66_history_auto_save_copy/02_tests_and_commit.md` (unit pins + E2E `tests/e2e/test_history_copy.py` + regression + commit).
