refactor(slasher): rename ATTESTED_DESCENDANT_OF_INVALID -> PROPOSED_DESCENDANT_OF_CHECKPOINT_WITH_INVALID_ATTESTATIONS (#23468)

PhilWindle · web-flow · commit 819c328ec264 · 2026-05-22T11:07:36.000+01:00
## Summary Closes [A-1073](https://linear.app/aztec-labs/issue/A-1073). Rename the slashing offence (and its config knob, env var, helm value, terraform variable, deploy script, README, ops docs) so the name spells out the exact condition: a descendant of a checkpoint that had **invalid (or insufficient) attestations**. The behaviour change itself lives in A-1072 — this PR is rename-only. - `OffenseType.ATTESTED_DESCENDANT_OF_INVALID` → `PROPOSED_DESCENDANT_OF_CHECKPOINT_WITH_INVALID_ATTESTATIONS` - Config field `slashAttestDescendantOfInvalidPenalty` → `slashProposeDescendantOfCheckpointWithInvalidAttestationsPenalty` - Env var `SLASH_ATTEST_DESCENDANT_OF_INVALID_PENALTY` → `SLASH_PROPOSE_DESCENDANT_OF_CHECKPOINT_WITH_INVALID_ATTESTATIONS_PENALTY` - Helm value, terraform variable, network defaults, deploy script - README + ops docs ## Test plan - `yarn build` (yarn-project) - `yarn format`, `yarn lint slasher stdlib foundation aztec-node` - `yarn workspace @aztec/slasher test` - `yarn workspace @aztec/stdlib test src/slashing` - `yarn workspace @aztec/stdlib test src/interfaces/aztec-node-admin.test.ts`
