No discovery nominations bundle found. Searched:\n{_searched

Error message

No discovery nominations bundle found. Searched:\n{_searched_lines(searched)}\n{_RESWEEP_REMEDY}

What it means

`load_nominations_bundle` raises HandoffContractError (exit 2) when no `discover-nominations.json` exists in any searched location. Search is strict: the save dir when `--save-dir` was supplied, else the config dir — never a cross-store fallback. The message lists the exact paths searched and appends the re-sweep remedy ('Run a fresh `--discover --nominate-only` re-sweep').

Solutions

1. Run leg 1 first: `--discover --nominate-only`, and use the SAME `--save-dir` (or same config dir) for every subsequent leg.
2. Verify the file exists at the path printed in 'Searched:' — it should be `discover-nominations.json` inside that dir.
3. If the bundle is genuinely absent (new machine, cleaned dir), re-run the nominate-only sweep to regenerate it, then re-author judgments against the new bundle_id.
4. Do not hand-copy the bundle to another store hoping for fallback — resolution is save-dir-else-config-dir by design.

Example fix

# before
python3 last30days.py "topic" --discover --judgments judgments.json   # no leg 1 ever ran
# after
python3 last30days.py "topic" --discover --nominate-only --save-dir /tmp/run
python3 last30days.py "topic" --discover --judgments judgments.json --save-dir /tmp/run

When it happens

Trigger: Invoking leg 2 (`--discover --judgments <file>`) before ever running leg 1; running leg 1 with `--save-dir A` and leg 2 with `--save-dir B` or no save dir; running leg 2 on a machine/container that never saw the bundle.

Common situations: Multi-step protocol split across sessions where leg 1 ran in a different directory or host; agents resuming a discovery run in a fresh sandbox; the user deleting/`clean`ing the save dir between legs.
