Expose run-discord-scrape.sh salvage and run-documents-scrape.sh --salvage-only so operators can merge quiescent .dce-temp partials without re-downloading from Discord after stopping a long or OOM-aborted run.

origin: /lfg — yes_general has 154MB+ active partial temp while full-target validation runs; operator needs to merge stale temps without re-downloading years of history after stopping a run

# feat: Salvage-only mode for stale temp exports
|
||
|
||
## Summary
|
||
|
||
Add a `salvage` subcommand that merges quiescent `.dce-temp` exports into archives without calling Discord, wired through the host runner and `run-documents-scrape.sh --salvage-only`.
|
||
|
||
## Problem Frame
|
||
|
||
After stopping a long-running or OOM-aborted export, operators must advance the archive cursor from preserved partial temps. Today salvage only runs at the start of a full `scrape`, which re-fetches from the archive `--after` cursor and can repeat multi-year catch-up on `yes_general`.
|
||
|
||
## Requirements
|
||
|
||
| ID | Requirement |
|
||
|----|-------------|
|
||
| R1 | `run-discord-scrape.sh salvage` merges stale temps per resolved channel; no Discord CLI export calls |
|
||
| R2 | Salvage mode does not require `DISCORD_TOKEN` |
|
||
| R3 | Existing `DCE_SALVAGE_ACTIVE_TEMPS=1` and `DCE_STALE_TEMP_MIN_AGE_SECONDS` env behavior applies |
|
||
| R4 | `run-discord-scrape-host.sh salvage` acquires archive-root lock and runs salvage locally (no compose/token) |
|
||
| R5 | `run-documents-scrape.sh --salvage-only` skips preflight/scrape and invokes host salvage |
|
||
| R6 | Smoke covers salvage subcommand; `run-all-smokes.sh` passes |
|
||
|
||
## Key Technical Decisions
|
||
|
||
- **Local host execution for salvage**: Avoids compose/token requirements; salvage is filesystem-only.
|
||
- **Reuse `salvage_stale_temp_exports`**: Same merge path as scrape preamble; no duplicate logic.
|
||
|
||
## Implementation Units
|
||
|
||
### U1. Core salvage subcommand
|
||
|
||
**Goal:** `salvage_only_target` + `run_target_mode salvage` without token gate.
|
||
|
||
**Requirements:** R1–R3
|
||
|
||
**Files:** `scripts/run-discord-scrape.sh`, `scripts/tests/run-discord-scrape-smoke.sh`
|
||
|
||
### U2. Host and documents wiring
|
||
|
||
**Goal:** Operator entry points for salvage-only.
|
||
|
||
**Requirements:** R4–R5
|
||
|
||
**Files:** `scripts/run-discord-scrape-host.sh`, `scripts/run-documents-scrape.sh`, `scripts/tests/documents-scrape-smoke.sh`
|
||
|
||
### U3. Smoke gate
|
||
|
||
**Requirements:** R6
|
||
|
||
**Verification:** `DCE_MIN_FREE_MB=0 ./scripts/run-all-smokes.sh`
|
||
|
||
## Scope Boundaries
|
||
|
||
### Deferred
|
||
|
||
- Killing stale validation on host
|
||
- Live yes_general catch-up inside LFG
|
||
- Container memory tuning
