Copy the nested role lists in the seed loader.
The returned metadata shares each roles list with STATIC_FREE_SEED. For example, appending "review" to the returned Gemma role list changes all later default bootstraps. This can admit a model to a role that the static seed excludes.
Copy the nested lists, or use deepcopy, so each returned seed is independent.

Include the current sample in record confidence.
append() passes the number of prior samples to to_record(). This line then stores confidence for that prior count. The first aggregate reports n=1 with confidence 0.0. The third reports n=3 with confidence 0.2, although confidence(3) returns 0.5.
Calculate the stored confidence from n_prior + 1 so it matches the sample count reported by aggregate().

Commit the in-memory sample after persistence succeeds.
If directory creation or file writing fails, append() raises after adding the record to _samples. The live aggregate then counts evidence that the JSONL ledger does not contain. A retry can count the failed sample again, and reopening the ledger produces a different result.
For a file-backed ledger, add the record to _samples only after the write and file close succeed. Keep the immediate append for an in-memory ledger.

Give each bet a stable, distinct record ID.
Two bets from different actor_id values receive the same entry_id when their actor class, subject, and prediction match. Bets on different head_sha values also collide. place_bet() retains both records, so entry_id cannot identify one bet for settlement or deduplication.
Generate an ID once per BetEntry and retain it across serialization. If retries must share an ID, accept an explicit idempotency key. Do not derive record identity only from these shared attributes.

Preserve an explicitly empty candidate table.
When a caller passes weights={}, this expression replaces the empty table with the static seed. Series selection then returns a model instead of no candidate. Parallel and concurrent selection also populate candidates outside the supplied table.
Use the default seed only when weights is None.

Require explicit free-model eligibility.
A supplied table such as {"roles": {"triage": {"paid/model": {"weight": 2.0}}}} passes this filter. The returned candidate also receives "free": True from Line 39. All three modes can therefore select a model whose free eligibility was never established.
Require meta.get("free") is True and use the same rule for the returned metadata. The bootstrap already excludes models without affirmative free metadata.
The PR objectives require free-only selection.
