cargo run --example repro_script_corruption -p aldabra-dao --release
Reads a hex-encoded Plutus V2 script, builds a minimal Conway tx
with that script as inline reference, calls build_conway_raw, then
searches the tx body for the input bytes verbatim. Also tests the
known on-chain block-swap corruption fingerprint (bytes 2390-2398
swapped with bytes 2416-2424) to determine whether pallas
reproduces the corruption locally.
If verbatim found: pallas is byte-clean, bug is downstream
(transport / Koios / chain submit). If swapped variant found:
pallas itself produces the corruption.
No chain query, no MCP, no JSON-RPC — pure local serialization.
Companion to dump_governor (committed earlier this branch). Edit
owner_pkh_hex + staked_amount in the source, then `cargo run` to
print the inline datum CBOR for a wallet_plutus_mint_unsigned call
that mints StakeST + sends to stakes_addr.
No locks at bootstrap (locked_by = []) and no delegation
(delegated_to = None). For a stake that's been used in proposals,
locked_by would carry the ProposalLock entries; reuse this scaffold
when reseeding a stake from a snapshot.
Without language_view, pallas does not compute script_data_hash on
the tx body. Plutus txs without script_data_hash get rejected with
ConwayUtxowFailure (PPViewHashesDontMatch SNothing (SJust ...)).
Caught 2026-05-07 attempting governor bootstrap on preprod against
Agora's V2 GST policy. Previous code only set language_view when
the policy was V3 — every V2 mint hit the chain rejection.
Three changes:
1. crates/aldabra-core/src/plutus_cost_models.rs — append
PLUTUS_V2_COST_MODEL_PREPROD constant (175 i64 entries), pulled
live from preprod Koios epoch_params 2026-05-07. Same protocol-
version convention as the existing V3 constant: V2 cost model
is identical mainnet vs preprod (cost models are protocol-version
parameters, not network), so the _PREPROD suffix is naming
convention, not a separation point.
2. crates/aldabra-core/src/plutus_mint.rs — replace the V3-only
language_view block with a per-PlutusVersion match. V2 wires
the new constant; V3 keeps the existing
params.plutus_v3_cost_model path; V1 left as TODO with a note
(no V1 mint use case yet).
3. crates/aldabra-dao/examples/dump_governor.rs — small cargo
example that encodes a sample GovernorDatum to CBOR hex via
the existing aldabra_dao::agora::GovernorDatum::to_plutus_data
path. Used during preprod DAO bringup to construct the inline
datum for the governor bootstrap tx. Edit values + re-run for
any DAO bringup. Builds against the existing pallas-codec
dev-dependency.
