phase: 193_sync_remaining_count

**Phase 193 — final verification pass: all gates green.**

- **Verified (all 3 tasks already complete in `complete/193_sync_remaining_count/`):** `fmtSyncLabel`'s count part is `total > 0 && total - done > 0 ? \`${total - done} remaining\` : ""` (plain int, hidden at `N==0`, `total===0` → no part); docstrings updated; chunk/image/summaries parts + `counts_line` terminal + `app/` byte-untouched (`git diff --stat`: no `app/` files).
- **Completion criteria:** `N remaining` shape + marker pins ✅ · upload shares the builder (E2E upload arm) ✅ · chunk/image/summaries pins green ✅ · terminal `counts_line` green unedited + A4 title/`#sync-progress` pin ✅ · suite green, coverage 99% ✅ · lint/types clean ✅ · commit + `todo/→complete/` left to the harness (no git index/history commands run).
- `uv run pytest -q --cov=app --cov-report=term-missing` → **exit 0**, junit: **4792 tests, 0 failures/errors/skipped**, `TOTAL 7181 16 → 99%` (>90%)
- `uv run pytest tests/e2e/test_sync_remaining_count.py -v --no-cov` → **3 passed** (isolated, 53 s)
- Isolated `--no-cov` sweep of the 14 sync-lineage suites (label_mobile, upload_progress, chunk_progress, image_progress, progress_box, summary_visibility, archive_upload_sources, status_freshness, upload_no_scan, peak_memory_visible, session_reset, fast_path_deferred_content, git_freeze, smoke) → **14/14 exit 0**
- `uv run ruff check .` → All checks passed · `uv run pyright` → **0 errors**
- **Docs:** README.md reviewed in full (all 2408 lines) + AGENTS.md. Fixed 2 inconsistencies: the sync running-label clause claimed the upload label shows the count — now states it shares the ONE builder/shape but reports no counts since phase 90 (renders bare); phase-190's "the other ~72 rows" → "the other 83 rows of the panel's 86-row catalogue" (mechanically: 86 CATALOG rows, 84 overridable). `N remaining` already in the sync paragraph; task-01's `(n/m)` examples gone. AGENTS.md verified consistent (no clause names the running count part → unchanged per the phase's "do not add if absent"). Mechanically re-verified: all 86 `BOR_*` settings documented + defaults match, `.env.example` 88 vars covered, 0 broken README anchors, all cited file paths exist, 17 palette colors, migrations head `0030`, pages/shell routes, ports 8123/8901, E2E port allocations (new suite's 8211/8914 unique).
- **Notable:** task 02's documented deviation stands — `files_done` is the importer's 1-based *current* file, so the phase doc's `[1-4]` range is unreachable; count-bearing frames are `1 … N−1` (pinned). Pre-existing, untouched: `E2E_APP_PORT_TOOLBUDGET`/`SAVEDOC` both 8129 and `SYNCUP`/`SYCNCEL` both 8133 — harmless under the one-suite-at-a-time rule.
- **Next pending phase:** none — `193_sync_remaining_count` is the last entry in `.agents/phases/todo/`.

+**Task 01 complete — `fmtSyncLabel` count part is now `N remaining` (D1).**
+
+**Implemented**
+- `frontend/assets/sources.js` — `fmtSyncLabel` count: `total > 0 && total - done > 0 ? `${total - done} remaining` : ""` (pre-walk `total > 0` guard kept, hidden at `N == 0`, plain integer, upload shares via the one builder); `fmtSyncLabel` + `fmtSyncPhaseLabel` docstrings updated to the count-down shape (lineage kept; summaries `(n/m)`, `· chunk n/m`, `· image n/m`, terminal `counts_line`, `setSyncLabel`/`#sync-progress` and the server/payload untouched).
+- `tests/unit/test_frontend_sync_upload.py` — new marker pins `test_fmt_sync_label_count_part_is_the_n_remaining_part` (exact expression, both guards, no-separator, docstring clauses incl. the hidden-at-final-file edge + upload sharing) and `test_remaining_part_leaves_the_other_parts_byte_identical` (chunk/image/summaries builders + `fmtSyncResult` unchanged); retargeted the `(2/3)` contract/harness pins to `1 remaining`; node harness gained the `import-final` row (count part behaviorally hidden at N == 0) wired into the chunk/image/box/Cancel loops; module docstring + `_doc_above` helper added.
+- `README.md` — sync running-label description: "Syncing… <file> (n/m)" → "Syncing… <file> N remaining" with the N = total − done / hidden-at-final-file / upload-sharing clause. `AGENTS.md`: verified no clause names the count part — no change (per phase doc note).
+
+**Gates (all green)**
+- `uv run pytest tests/unit/test_frontend_sync_upload.py` → pass (incl. node harness)
+- `uv run pytest --cov=app --cov-report=term-missing` → **4792 passed**, `app/` coverage **99%** (>90%)
+- `uv run ruff check .` → clean; `uv run pyright` → clean
+
+**Decisions / deviations**
+- E2E running-label count pins (`test_sync_label_mobile.py`, `test_sync_upload_progress.py`, `test_sync_chunk_progress.py`, `test_sync_image_progress.py`, `test_sync_progress_box.py`) are deliberately left for **task 02** ("the pinned suites move"), per phase 193 D2 — the project's default suite (`testpaths`: unit+integration) is 100% green.
+
+**Next pending task:** `193_sync_remaining_count/02_update_pinned_e2e.md`

+**Task 02 complete — every running-label count pin now asserts `N remaining`.**
+
+**Implemented (test-only + doc hygiene)**
+- `tests/e2e/test_sync_label_mobile.py`: `IMPORT_COUNT_RE`/`IMPORT_FULL_RE` + both in-browser JS regexes → `[1-3] remaining` (4-file fixture; `files_done` is the importer's **1-based current file**, so N = 4−done ∈ {3,2,1} and the last file renders no part — the phase doc's "`done = i − 1`" arithmetic was wrong); `IMPORT_MAIN_RE` untouched.
+- `tests/e2e/test_sync_upload_progress.py`: the 4 box/title count regexes → `(?: [0-9]+ remaining)?` (optional — see deviations).
+- `tests/e2e/test_sync_chunk_progress.py`: JS `count.textContent`, `countText`, the composed A4 string → `1 remaining` (big.md = file 1 of 2).
+- `tests/e2e/test_sync_progress_box.py`: the 3 JS waits + 2 Python asserts → `2 remaining` (long file = file 1 of 3).
+- `tests/e2e/test_sync_image_progress.py`: the single-file fixture's `(1/1)` pin became the **hidden-at-final-file** arm (`no running label carries " remaining"` + the live-file label still pinned).
+- Phase-193 lineage sentence added to each retargeted module docstring; stale `(n/m)` prose fixed in `test_archive_upload_sources.py`, `test_sync_status_freshness.py`, `test_upload_no_scan.py`, `tests/unit/test_sync_button.py`, `tests/unit/test_frontend_sync_upload.py`.
+- **Untouched and green**: the `· chunk n/m` / `· image n/m` parts, the summaries `(n/3)` folder position, and every `counts_line` terminal pin (`git_freeze`, `session_reset`, `fast_path_deferred_content`).
+- Pin list closed: the remaining hits of the phase's grep are bare `"Syncing…"` asserts and the owner's quoted reports.
+
+**Gates**
+- `uv run pytest` → **4792 passed**; `uv run pytest --cov=app --cov-report=term-missing` → **99%** (>90%).
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors.
+- E2E (`--no-cov`, isolated): `test_sync_label_mobile.py + test_sync_upload_progress.py` 8 passed (the task's combined command); `test_sync_progress_box.py` 8; `test_sync_chunk_progress.py + test_sync_image_progress.py` 4; `+ test_sync_summary_visibility.py` 7; `test_sync_git_freeze.py` 2; `test_archive_upload_sources.py + test_sync_session_reset.py` 9; `test_fast_path_deferred_content.py + test_sync_button.py + test_sync_peak_memory_visible.py` 11; `test_sync_status_freshness.py + test_upload_no_scan.py` in the summary batch.
+
+**Docs**: README's sync running-label paragraph — removed the stray `— and —` the task-01 edit left and re-flowed the wrap; AGENTS.md has no count-part clause (no doc impact for it; task 03 re-verifies).
+
+**Deviations**: (1) the phase's D2 range `[1-4] remaining` is impossible — `files_done` includes the in-flight file, so the count-bearing frames are `[1-3]` (kept **mandatory** where the pin's whole point is "the count is in the text"); (2) the upload suite's 25-file box/title pins make the part **optional**, because its 2 s poll can land exactly on the final file where A1 hides the part — the pattern still rejects a pre-phase `(n/m)` tail.
+
+**Next pending task**: `.agents/phases/todo/193_sync_remaining_count/03_e2e.md`.

+**Task 03 complete — phase 193's own E2E suite is green in isolation; all gates green.**
+
+**Implemented**
+- `tests/e2e/test_sync_remaining_count.py` (NEW): a real `file://` git fixture (5 docs, first + last multi-chunk) + the slow-LLM proxy, with a MutationObserver that records EVERY value the one label writer lands (`#sync-progress-text`, button `title`/`aria-label`, `.sync-label-count` visibility). Arms: **(a)** the count-down — grammar `^Syncing… <file> [1-4] remaining(?: · chunk n/m)?$`, rendered `N`s strictly decreasing 4→3→2→1, never 0/≥total, chunk part coexisting (its `m` = the file's real `chunk_document` count), NO count part once the final file is named and never returning, the overview + summaries `(n/m)` phases intact, the terminal `counts_line("5 added")` byte-identical, plus the cross-layer invariant that every rendered `N` equals `files_total − files_done` of the untouched payload; **(c)** the pre-walk `phase:null`/`files_total:0` → bare `Syncing…` and the hidden-at-final edge, pinned on served bodies of the endpoint's unchanged key set; **(b)** the upload arm through the same builder (`Importing <file> N remaining`, hidden at its final file).
+- Docs pass: the stale `(n/m)` running-label examples became `N remaining` in `frontend/assets/sources.js` (5 header/comment sites), `frontend/assets/styles.css`, `frontend/index.html`, `frontend/assets/git-sources.js`. `README.md` already carried the phase-193 label (task 01); `AGENTS.md` has no clause naming the running count part — unchanged.

+**Gates (final state)** `uv run pytest --cov=app --cov-report=term-missing` → exit 0, `app/` **99%**; `tests/e2e/test_sync_remaining_count.py -v --no-cov` → 3 passed in isolation (twice); regression `test_sync_label_mobile + test_sync_upload_progress + test_sync_chunk_progress + test_sync_summary_visibility` → 13 passed; `ruff check .` clean; `pyright` 0 errors.
+
+**Decisions / deviations**
+1. A2's upload arm is not observable live: since phase 90 the upload status answers `null/0/0` for the whole run (asserted against the live endpoint inside that test), so the shared *shape* is pinned through a served status body (the house `page.route` pattern) — the client's `total > 0` / `total − done > 0` guards are what is under test, the server stays untouched.
+2. The upload frame can never carry `· chunk n/m` (that branch receives no status object — phase 129/152), so the coexistence pin sits in the sync arms and the upload test asserts the frame stays chunk-free.
+3. Count-bearing frames are `1 … N−1` (`files_done` is the 1-based in-flight file) — task 02's finding, kept here.
+4. No git commands run and the phase directory was not moved, per the harness instruction — commit + `todo/ → complete/` left to the harness.
+
+**Next task:** none pending in `193_sync_remaining_count` (03 is its last).
