Conversation
Add synthetic (snapshot-free) coverage for the extracted compute_initial_pledge_for_power and the StateMinerCreationDeposit handler: - before network version 27, the handler returns a zero deposit without reading the state tree - at version 27 and later, the deposit is computed from hand-built power and reward actor states, covering both the active pledge-ramp branch (ramp_start_epoch > 0) and the no-ramp branch The tests build a state tree containing the power, reward, burnt-funds and reserve actors that the calculation and circulating-supply read, using the real v18 actor code CIDs from the embedded bundle metadata. compute_initial_pledge_for_power now takes &StateManager instead of &Ctx so the calculation can be exercised without a full RPC context; the handler call sites pass &ctx.state_manager. Closes ChainSafe#7503

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR adds synthetic coverage without changing production behavior, so it is mergeable with owner awareness. The bounded risk is that weak expected-value and activation-boundary assertions could miss calculation or network-schedule regressions, while state-read failures would provide limited diagnostic context.

Full details: Linked Issues checkExplanation The changes cover deterministic pre-V27 and V27 calculation tests, pledge-ramp branches, and the StateManager refactor. The provided summary does not show coverage for calibnet configuration, post-V27 behavior, or an explicit one-tenth minimum-consensus-power assertion required by issue Resolution Add or document tests for mainnet and calibnet activation paths, include a post-V27 case, and assert that the deposit derives from one-tenth of minimum consensus power. Confirm that existing API parity and snapshot tests remain in the suite. [

Add context to initial-pledge state reads.
The state-tree, actor-state, and circulating-supply failures do not identify the initial-pledge operation. Add .context(...) at these boundaries before conversion to ServerError.
As per coding guidelines, “Use anyhow::Result<T> for most operations and add context with .context() when errors occur.”

Assert deterministic pledge values.
These tests only require a positive result. A change that ignores ramp parameters or uses a value other than one-tenth of minimum consensus power still passes.

Test configured V27 activation boundaries.
The tests do not use the configured mainnet and calibnet upgrade schedules. Forcing genesis_network to V27 bypasses the calibnet activation path. A wrong V27 activation epoch can still pass.

Summary of changes
Adds synthetic (snapshot-free) test coverage for
Filecoin.StateMinerCreationDepositand the extractedcompute_initial_pledge_for_power, as requested in #7503. Tests are deterministic and network-free, per the guidance to keep them synthetic rather than snapshot-based.Changes introduced in this pull request:
creation_deposit_testsmodule insrc/rpc/methods/state.rs:creation_deposit_is_zero_before_v27— the handler returns a zero deposit before network version 27 without reading state.creation_deposit_positive_at_v27— the handler computes a positive deposit at v27 from hand-built actor state.compute_initial_pledge_with_active_ramp/compute_initial_pledge_without_ramp— cover both branches of the pledge-ramp selection (ramp_start_epoch > 0and== 0).ACTOR_BUNDLES_METADATA).compute_initial_pledge_for_powernow takes&StateManagerinstead of&Ctx, so the calculation can be exercised without constructing a full RPC context. The two call sites pass&ctx.state_manager; no behaviour change.Between the four tests,
compute_initial_pledge_for_powerand theStateMinerCreationDeposithandler (both the pre-v27 gate and the v27 path) are fully exercised.Reference issue to close (if applicable)
Closes #7503
