* fix(state_machine): reject public transactions that silently drop a declared account
ValidatedStateDiff::from_public_transaction never checked that the accounts
touched in a program's output matched the caller-declared message.account_ids
— it just folded whatever pairs the program returned into the diff. A program
(or a macro-generated dispatcher wrapping one) that silently drops an account
from both sides of its own output together stays internally consistent
(pre_states.len() == post_states.len()) and passes validate_execution's
existing checks, so the dropped account simply vanishes with no error.
Add a check after the chained-call loop: every account_id in
message.account_ids must appear in the final state_diff, or the transaction is
rejected with the new DeclaredAccountMissingFromOutput error.
Add a dropped_account test-guest program that reproduces the exact shape of
the bug (two pre_states in, one consistent (pre, post) pair out) and a
regression test proving the transaction is now rejected. Verified the test
fails with Ok(()) when the check is removed, and passes once it's restored.
* style: tighten comments and apply nightly rustfmt
Condense the explanatory comments on the new account-accounting check and the
dropped_account test guest, and fix imprecise wording (the account is dropped
from both pre_state and post_states together, not just pre_state). Also
applies cargo +nightly fmt's wrapping of the new error message.
* chore: regenerate test fixture after rebase onto dev
BREAKING CHANGE:
- Crate `nssa` renamed to `lee`; update `Cargo.toml` dependencies from `nssa = { workspace = true }` to `lee = { workspace = true }`.
- Crate `nssa_core` renamed to `lee_core`; update similarly.
- Crate `key_protocol` moved under `lee`; update `Cargo.toml` dependencies from `key_protocol = { workspace = true }` to `lee_key_protocol = { workspace = true }`.
- Type `NSSATransaction` (in `common`) renamed to `LeeTransaction`.
- Error type `nssa::error::NssaError` renamed to `lee::error::LeeError`.
- Error type `nssa_core::error::NssaCoreError` renamed to `lee_core::error::LeeCoreError`.
- All `use nssa::` and `use nssa_core::` import paths must be updated to `use lee::` and `use lee_core::` respectively.
- Guest programs must replace `write_nssa_outputs` with `write_lee_outputs`.
- The sequencer RocksDB column family for the chain state was renamed. Existing databases are incompatible and must be wiped before running the new version.
- Domain separators updated: `"NSSA_seed"` → `"LEE_seed"` (key derivation), `"NSSA/v0.2/KDF-SHA256/"` → `"LEE/v0.2/KDF-SHA256/"` (encryption KDF), `"/NSSA/v0.2/AccountId/PDA/"` →
`"/LEE/v0.2/AccountId/PDA/"` (public PDA address derivation). All previously derived keys, encrypted outputs, and public PDA addresses are invalidated.
