local-only preservation cannot contain candidates or inserts

Error message

local-only preservation cannot contain candidates or inserts

What it means

Local-only mode is strictly a preservation bundle: it must contain zero candidates and zero inserts. If either collection is non-empty while local_only is True, the bundle would silently mix provider-derived edits into a 'preservation' artifact, so it is rejected.

Solutions

1. Set cfg['candidates'] = [] and cfg['inserts'] = [] before local-only bundling
2. Build the bundle with local_only=False if you actually want the candidates/inserts applied
3. Split the config: preservation-only config for local_only, full config for hosted mode

Example fix

// before
build_application_bundle({**cfg, "inserts": [ins]}, None, local_only=True)
// after
build_application_bundle({**cfg, "inserts": [], "candidates": []}, None, local_only=True)

if local_only and (cfg.get("candidates") or cfg.get("inserts")):
    raise ValueError("local-only mode requires empty candidates and inserts")

def is_preservation_only(cfg):
    return not cfg.get("candidates") and not cfg.get("inserts")

try:
    bundle = build_application_bundle(cfg, None, local_only=True)
except ValueError as e:
    if "cannot contain candidates or inserts" in str(e):
        cfg = {**cfg, "candidates": [], "inserts": []}
        bundle = build_application_bundle(cfg, None, local_only=True)
    else:
        raise

When it happens

Trigger: build_application_bundle(cfg, None, local_only=True) where cfg['candidates'] or cfg['inserts'] is a non-empty list (e.g. leftover insert entries from a previous hosted run).

Common situations: Re-running a previous hosted bundle build with local_only flipped on without clearing proposals; a generic template that always emits empty-ish but non-empty default candidate arrays.
