fix(scrape): skip SIGTERM/SIGINT export aborts like OOM

Stopping validation with kill/Ctrl+C returned exit 143/130 and failed
the whole target instead of SKIPPED + preserve partial. Added smoke for
exit 143; gitignore .dce-scrape.lock.

+type: fix
+status: complete

+origin: /lfg — yes_general died with fatal ERROR instead of SKIPPED when validation was stopped

+
+# fix: Treat SIGTERM/SIGINT export aborts as skippable
+
+## Problem
+
+Killing overlapping validation (`kill` / Ctrl+C) sends SIGTERM/SIGINT to the export CLI. Bash exit codes **143** (128+15) and **130** (128+2) were not in the abort-skip list, so `scrape_target` called `die` and failed the whole target — losing partial temp progress instead of SKIPPED + preserve.
+
+Observed: `ERROR: Channel 221726893064454144 failed` at 7% progress in `logs/kotor-validation-20260604.log`.
+
+## Requirements
+
+| ID | Requirement |
+|----|-------------|
+| R1 | `export_channel_incremental` returns skip (2) on exit 130 and 143, same as 134/137/139 |
+| R2 | Partial temp preserved on those skips when `temp_export` non-empty |
+| R3 | Offline smoke covers exit 143 skip path |
+| R4 | `.gitignore` includes `.dce-scrape.lock` |
+| R5 | `run-all-smokes.sh` passes; docs updated |
+
+## Verification
+
+```bash
+./scripts/tests/run-discord-scrape-smoke.sh
+DCE_MIN_FREE_MB=0 ./scripts/run-all-smokes.sh
+```
+
+## Out of scope
+
+- Completing yes_general catch-up inside LFG
+- Container memory tuning

 \* Audit failed before plan 045 because truncated partial exports under `.dce-temp/` were scanned as archives. After fix, audit passes while partial temps exist.
 
+**Plan 047 (2026-06-04):** Treat SIGTERM (143) and SIGINT (130) export exits as skippable aborts — stopping validation no longer fails the whole target with `ERROR: Channel failed`. `.dce-scrape.lock` gitignored.

 **Plan 046 (2026-06-04):** `run-discord-scrape-host.sh scrape` holds non-blocking `flock` on `.dce-scrape.lock` so overlapping manual/cron validation cannot spawn twin yes_general exports. Stop duplicate runs before restarting KotOR validation.
 
 **Plan 045 (2026-06-04):** `audit-archive-json.sh` and `verify-documents-archives.sh` skip `*/.dce-temp/*` (in-progress partial exports). Salvage run 2026-06-03: 7 merged, 17 unchanged, 3 skipped (+5404 messages); yes_general OOM-skipped with partial temps preserved for next salvage.
