chore: establish contributor and release workflows 🏗️

[kp2pml30]

Delivery Context

Executor mirror for genlayerlabs/genvm-manager#30

Executor head: ee7b55133b637acd22118ed06ff52f233b21366a

Problem And Outcome

Retained executor outputs needed uniform RAM accounting, and leader-proposed nondeterministic output needed fee and RAM enforcement before validation or publication

This change adds permanent-allocation accounting, applies nondeterministic caps consistently across consensus paths, and retains only capped output

Implementation

• Metered retained storage, messages, events, deploy code, and nondeterministic output against RAM
• Added fee and RAM preflights for nondeterministic output with contract-visible fallback errors
• Validated leader-proposed output before publication and preserved validator mismatch handling
• Added integration and unit coverage for output caps and permanent memory accounting
• Added real-handler regression coverage for external, internal, balance-funded, and deploy messages plus events on RAM and fee rejection

Validation

• Executor library: 115 passed
• Full !needs-fuzz & !bench suite: 1,897 passed, 0 failed
• Debug build passed
• Executor and cross-repository commit hooks passed
• Independent re-review of the new emission tests found no remaining issues

Non-Goals

No cross-repository E2E, merge, or release is requested by this update

Summary by CodeRabbit

• Documentation

  • Updated pre-mainnet vulnerability reporting guidance and private reporting destination.
  • Clarified trust boundaries and documented untrusted input sources.

• Bug Fixes

  • Improved memory and fee accounting for storage updates, messages, events, deployments, and nondeterministic execution results.
  • Prevented resource-limit bypasses when permanent allocations are created or combined.
  • Ensured resource charges are applied atomically and rejected operations do not consume budgets.

📝 Walkthrough

Walkthrough

The executor adds permanent memory accounting for storage pages, emitted messages and events, and nondeterministic outputs. Fee checks become atomic and support nondeterministic output preflight. The security policy updates vulnerability reporting guidance and documents trust boundaries and untrusted inputs.

Changes

Permanent memory accounting

Layer / File(s)	Summary
Allocation primitives and sizing executor/crates/common/src/internal_constants.rs, executor/src/rt/memlimiter.rs, executor/src/wasi/genlayer_sdk/mod.rs	The memory limiter adds permanent allocation reservation, folding, inspection, and RAII cleanup. Constants and helpers calculate allocation sizes and handle overflow.
Storage page accounting executor/src/rt/vm/storage.rs	New storage pages reserve permanent memory before fee consumption and commit after success. Child overrides transfer permanent usage during folding.
Atomic fee checks executor/src/rt/fees.rs	Fee consumption checks all bucket costs before deduction and exposes nondeterministic output preflight checks.
Emission accounting executor/src/wasi/genlayer_sdk/message.rs	Message, event, internal message, and deployment paths reserve memory from payload sizes and commit after publication.
Nondeterministic output charging executor/src/wasi/genlayer_sdk/run.rs, executor/src/wasi/genlayer_sdk/tests.rs	Nondeterministic outputs use RAM and fee preflight checks, capped fallback outputs, permanent charging, and leader-output validation before validator submission.

Security policy

Layer / File(s)	Summary
Reporting guidance and trust boundaries SECURITY.md	Before mainnet, the policy directs non-RCE reports to public issues and RCE reports to private vulnerability reporting through genvm-manager. It removes the email contact and adds trusted relationships and untrusted input categories.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to ee7b5

This change adds permanent RAM and fee accounting to nondeterministic outputs, but charges may remain committed after later validation or publication failures, and related accounting and policy-synchronization concerns remain open. These bounded merge-readiness risks require explicit owner acceptance or follow-up before merging.
