In `@crates/cardano/src/pallas_extras.rs`:
- Around line 459-462: Update the RedeemerTag::Mint branch to index into
tx.mints_sorted_set() instead of tx.mints(), preserving the existing policy
extraction and optional return behavior.
- Around line 396-407: The vote_redeemer index ordering in vote_script_hash must
match ledger CBOR ordering, with key credentials ordered before script
credentials rather than relying on minicbor byte sorting. Update the voters
sorting logic to reproduce that ordering while preserving deterministic ordering
within each credential type, and add a regression test covering mixed key and
script voters to verify the correct script hash is selected.
In `@crates/minibf/src/mapping.rs`:
- Around line 1438-1442: Update build_redeemer_inner to return None for
unsupported Vote and Propose redeemer purposes instead of converting them to an
internal-server error, while preserving existing errors for other failures. In
into_model, filter out successful None results and retain supported redeemers
and propagated errors so unsupported governance redeemers do not fail the entire
response.
- Around line 1376-1384: In the parameter-conversion flow around the mem_price
and step_price BigRational constructions, validate both RationalNumber
denominators before calling BigRational::new; when either is zero, return
StatusCode::INTERNAL_SERVER_ERROR, otherwise preserve the existing conversions.
In `@crates/redb3/src/archive/indexes.rs`:
- Around line 362-373: Update compute_key to accept a byte slice (&[u8]) and
hash it directly with xxh3_64(script_hash). In iter_by_script_redeemers, pass
script_hash directly instead of allocating a Vec.
In `@docs/content/apis/minibf.mdx`:
- Line 154: Update the `/scripts/{script_hash}/redeemers` API documentation
entry to state that existing stores return redeemer rows only from the upgrade
point, and that full history requires a from-scratch sync or compatible
snapshot.

Scan the union of the archive dimensions a script can leave traces in
(script bytes, payment credential, policy, stake credential), then match
each redeemer to its script per tx. This finds executions through
reference scripts, which carry no script bytes in the tx.
The redeemer-to-script matching now also covers cert and reward
purposes, so /txs/{tx_hash}/redeemers reports script_hash for those
too.
… scan - blocks_by_tag_stream now delegates to blocks_by_tags_stream: one copy of the chunked cursor logic remains - the scripts handler reuses log_and_500 instead of hand-rolled tracing + 500 closures - the RedeemerTag-to-purpose policy (including the vote/propose gap) lives in mapping.rs, once per generated enum - by_hash_redeemers keeps HTTP concerns; scan_script_redeemers owns the scan loop, with prices_for_epoch as the memoized pparams lookup No behavior change: route tests and the official Blockfrost fixtures pass unchanged.
The scripts redeemers scan derives candidates from side-effect dimensions, and governance redeemers leave no side effect any dimension tags. Resolve the redeemer-to-script matching once, at index time, and tag each executed script under a new script_redeemers dimension. - the matcher moves to pallas_extras with a generic error type and gains vote and propose arms (voter credential, proposal policy script); the endpoints keep their Blockfrost-parity output, so the new purposes surface only as tags for now - index_block tags every resolvable execution, phase-2-failed txs included: tags are candidates, the Blockfrost rule stays a query-time filter - the scripts redeemers union gains the new dimension as its first key; stores synced before this commit lack the tags, and the union keeps those complete - redb3 (deprecated backend) gets the table and arms so the dimension works there too - the stele goldens re-pin: the canonical indexes layer carries one record per dimension, so its diffId, record count and inscription digest change deliberately
The union of side-effect dimensions existed to keep old stores complete while the script_redeemers dimension was new. Precedent says the transition story is a resync (#974, #976 shipped their dimensions the same way), so drop the union: the endpoint scans the exact dimension and nothing else. This removes the noise cases entirely — deposits into a script address and transfers of a policy's assets no longer produce candidate blocks. With the union gone, nothing needs a multi-tag scan anymore. Remove blocks_by_tags_stream and restore blocks_by_tag_stream to its original single-tag form. A store synced before the dimension serves only post-upgrade history on this endpoint; full history needs a store synced from scratch or a snapshot cut from one. Also rewraps a goldens doc comment that failed the nightly fmt gate.
The ledger indexes voters by its Map Voter order: script credentials sort before key credentials inside each group. The cbor tag order is the opposite. Pallas declares the Voter variants in ledger order, so the decoded BTreeMap already iterates correctly; drop the re-sort by encoding that inverted mixed-credential voter groups. Also index mint redeemers through mints_sorted_set to state the sorted-policy-set requirement explicitly.
One governance redeemer made /txs/{tx_hash}/redeemers return 500 and
hid every other row of the tx. Filter unsupported purposes out, the
same policy the scripts redeemers endpoint applies. Also guard the
fee computation against zero denominators, which panic BigRational.
Emission of vote and propose rows still waits on blockfrost/openapi#464.
Three query-path fixes for /scripts/{script_hash}/redeemers:
- Cap consumed candidate blocks at max_scan_items. The dimension is a
superset, so a script whose executions all filter out scanned its
whole tagged history on every request.
- Treat dimension activity as proof the script exists. On a pruned
node the block that carried the script bytes can age out while
tagged executions stay inside the window; the archive existence
lookup now runs only when the dimension shows nothing.
- Read the previous-epoch pparams from the next epoch log's mark slot
when the history cutoff pruned the oldest retained epoch's own log.
The happy path asserted an empty page because the synthetic chain executed no scripts. Add an opt-in mint_redeemer config to the synthetic blocks: the first tx of every block mints under the redeemer policy and carries one Mint redeemer; an optional phase-2 invalid tx carries a redeemer for the same policy. Default-config vectors stay byte-identical, guarded by a regression test. New route tests assert exact rows (tx hash, purpose, data hash, ex-units, hand-derived fee), desc as the exact reverse of asc, per-page pagination, and that the invalid tx contributes no row.
blockfrost-openapi 0.1.92 adds the two conway purposes to the generated enums. Map them, drop the skip filters, and make both purpose functions total — every RedeemerTag now has a purpose. Deliberate divergence from deployed Blockfrost, documented in code: db-sync leaves governance redeemers unattributed (script_hash ""), dolos resolves the voter credential and the guardrails script from the ledger. The script_redeemers dimension already tags these executions, so no store rebuild is needed.
