+# Open items — session 2026-06-17 (handoff notice)
+
+Everything still open after this session. Done items are in
+`docs/audit/DATA-QUALITY-2026-06-15.md` (DQ-1..DQ-5 + roadmap R-A,R-B,R-C,R-D,R-F all
+DONE; R-E deferred). This file is only the **loose ends**.
+
+## 1. BLOCKER — Jetson is offline
+- The Jetson (`192.168.178.103`) went **unreachable** mid-session: `ping` 100 % loss,
+  `ssh:22` timeout. It hosts Postgres (the live corpus) **and** GROBID.
+- **Blocks every live-DB action below.** First step next session: confirm it's powered
+  + on the network, bring the SSH tunnel back up
+  (`ssh -f -N -L 5433:localhost:5432 alfred@192.168.178.103`).
+
+## 2. PENDING — R-F accent re-clean (cosmetic, code already merged into the branch)
+- R-F is functionally DONE (section signal 34/329 → **314/329 = 95 %**), but a few live
+  `chunks.section` labels still carry LaTeX accents/ties (e.g. `m\"obius`, `colin~de~…`).
+- The `_clean_title` polish that fixes these is committed on `feat/section-labels`; the
+  **in-place re-clean of existing rows didn't finish** (Jetson went offline, item #1).
+- **Action when Jetson is back (short UPDATE, no re-ingest):** apply
+  `codex.quality._clean_title` to every `chunks.section` containing `\` or `~` and write
+  it back. Quick + idempotent — exactly the kind of short op that survives a flaky link.
+
+## 3. Git — feature branches not merged to `main`
+This session's work is on 5 branches off `audit/loop-1` (itself **18 commits ahead of
+`main`**). No PRs opened. Merge decision + order pending:
+
+| Branch | Contents | Commits ahead of main |
+|---|---|---|
+| `audit/loop-1` | base: DQ-1..DQ-5, **R-A** (GROBID backfill + native arm64 GROBID) | 18 |
+| `feat/tex-ingest` | **R-C** (.tex section-aware ingest) + DQ-5 arXiv-id fix + gzip fallback | 22 |
+| `feat/section-labels` | **R-F** (richer section labels) — **branched off `feat/tex-ingest`** | 25 |
+| `feat/crossref-references` | **R-B** (Crossref refs) + a concurrent GROBID-on-demand tweak | 20 |
+| `feat/graph-coverage-warning` | **R-D** (citing-coverage warning) | 19 |
+| `chore/infra-ssh-stability` | infra TODO doc (#4) | 19 |
+
+- **Order matters:** `feat/section-labels` contains `feat/tex-ingest`, so merge
+  `feat/tex-ingest` first (or merge section-labels alone, which brings both).
+- All branches share the `audit/loop-1` base, so merging any one brings that whole line
+  to `main` — decide whether to land `audit/loop-1` → `main` as the trunk first.
+
+## 4. Infra TODO — tmux-on-Jetson for stable long ops (documented, not implemented)
+- `docs/infra/jetson-ssh-stability.md` (branch `chore/infra-ssh-stability`). The
+  Mac↔Jetson tunnel dropped repeatedly on multi-minute writes all session. Fix: run long
+  ops **on the Jetson in `tmux`** (DB is localhost there → no tunnel; survives SSH drops);
+  `autossh` for interactive tunnels. Open.
+
+## 5. Known limitations (documented, NOT action items)
+- `math/0306167` (old AMS-TeX, no `\section{}`) stays `section=body` — inherent.
+- The 2 edited-volume books yielded 0 GROBID-parsed DOI/arXiv refs in the R-A sweep —
+  inherent (per-chapter refs, no clean end-bibliography).
+- **DQ-6** (upstream PDF→`.txt` extraction fidelity, done outside codex-py) — flagged
+  earlier, largely **mooted** by R-A/R-C ingesting from PDF/`.tex` directly.
