Phase 0: Fix Broken SDK (CRIT-01, CRIT-02, CRIT-03)

These are blocking bugs — the SDK literally cannot work correctly without these fixes.

  • CRIT-01 — CreditClient wrong token wiring: The credit() factory method was passing gld_token instead of spore_token. The Credit Vault contract works with SPORE, not GLD. Fixed in src/sdk/mod.rs and src/sdk/credit/vault.rs.
  • CRIT-02 — spend() ABI mismatch: The SDK spend() method was missing the payee parameter and used description instead of memo, not matching the contract's actual signature. Fixed in src/sdk/credit/vault.rs, src/cli/cli/credit.rs, src/cli/cli/execute.rs, src/cli/cmd.rs.
  • CRIT-03 — get_balance() calls non-existent method: Called get_balance which doesn't exist on the contract. Changed to use list_lines and sum balances across all lines. Fixed in src/sdk/credit/vault.rs.

Phase 1: Contract Data Integrity & Fund Safety

  • CRIT-04 — StorageKey collision in Credit contract: All nested Vector::new() and LookupMap::new() calls used the same static prefix, causing data corruption across different users' lines. Added parameterized StorageKey variants: LineIndexByOwner(AccountId), ApprovalIndexByKey(AccountId, u64). Fixed in contracts/credit/src/lib.rs.
  • CRIT-05 — ft_on_transfer panics on bad input: Changed signature to use U128 and PromiseOrValue<U128> per NEP-141 standard. Bad payloads now refund tokens instead of panicking. Fixed in contracts/credit/src/lib.rs.
  • HIGH-01/02 — DNS missing cross-contract callbacks: claim_refund and withdraw_fees had no callbacks, so failed token transfers silently lost funds. Added on_refund_complete and on_fee_withdraw_complete with proper rollback. Fixed in contracts/dns/src/lib.rs.
  • HIGH-03 — Faucet no access control: Anyone could call fund_account. Added authorized_relayers: UnorderedSet<AccountId> with add_relayer/remove_relayer admin methods. Fixed in contracts/faucet/src/lib.rs.
  • HIGH-04 — Hosting SLA forgery: sla_settle_period had no caller verification. Added admin field and admin-only check. Fixed in contracts/hosting/src/lib.rs.
  • HIGH-06 — Validator key file permissions: Key files written as world-readable. Added chmod 0600 after writes. Fixed in src/provision/config.rs, src/cluster_manager/cluster.rs.
  • MED-09 — SPOREX callback panics: amount.parse().expect() in withdrawal callbacks. Replaced with safe match handling. Fixed in contracts/sporex/src/lib.rs.

Phase 2: Supply Chain & Network Security

  • CRIT-06 — Unpinned git dependencies: All 5 git deps used branch = \"development\", allowing supply chain attacks. Pinned to specific commit hashes. Fixed in Cargo.toml.
  • HIGH-07 — Vault secret in service config: Secret exposed as env var in systemd config. Now written to a file with 0600 perms and referenced via EnvironmentFile. Fixed in src/provision/relayer_service.rs.
  • HIGH-08 — HTTP URLs for non-localhost networks: Dev/test network URLs used plain HTTP. Changed to HTTPS. Fixed in src/sdk/network.rs.
  • HIGH-09 — f64 arithmetic for NEAR amounts: (deposit_near * 1e24) as u128 loses precision. Replaced with integer-based whole/fractional split. Fixed in src/sdk/client.rs.
  • HIGH-11 — CLI secrets in shell history: --secret-key and --mnemonic visible in process list. Added stdin prompting when not provided as args. Fixed in src/bin/heroledger.rs.
  • MED-10 — Fake transaction hash: format!(\"deployed:{}\") returned as tx hash. Changed to clearly indicate no real hash. Fixed in src/sdk/contract_builder.rs.
  • MED-15 — Account Debug exposes private key: Custom Debug impl now redacts private_key. Fixed in src/sdk/mod.rs.
  • MED-16 — Docker image pinning: Added TODO comment for SHA pinning. Fixed in docker/Dockerfile.builder.

Phase 3: Hardening & Mainnet Readiness

  • CRIT-07/08 — Rhai RCE vectors: Removed run_command, run_command_output, and env_var functions from Rhai engine. Fixed in src/rhai/mod.rs.
  • HIGH-05 — SPOREX admin withdrawal: Added admin_withdraw_usdh and admin_withdraw_gld methods. Fixed in contracts/sporex/src/lib.rs.
  • MED-01 — Credit rate limit rollback: On spend failure, usage window counters are now decremented. Fixed in contracts/credit/src/lib.rs.
  • MED-03 — CORS restriction: Changed relayer from allow_methods(Any).allow_headers(Any) to specific [GET, POST] and [CONTENT_TYPE]. Fixed in src/cli/relayer.rs.
  • MED-05 — Groups HashSet: Added WARNING comments about full deserialization cost (migration concern, see future work). In contracts/groups/src/lib.rs.
  • MED-06 — Marketplace integer rounding: Changed to ceiling division to prevent rounding down to zero. Fixed in contracts/marketplace/src/lib.rs.
  • MED-07 — SPOREX reserve accounting: Exchange functions now decrement reserves properly. Fixed in contracts/sporex/src/lib.rs.
  • MED-17 — DNS auction griefing penalty: 10% penalty on unclaimed auction bids. Fixed in contracts/dns/src/lib.rs.

Build & Test Verification

  • cargo check — passes (main crate + all features)
  • cargo check --target wasm32-unknown-unknown — passes for all 7 modified contracts
  • cargo test95 passed, 0 failed, 21 ignored

Left for Future Work

ID Issue Reason Deferred
MED-02 Credit assert_one_yocto → storage deposit calculation Requires careful storage cost analysis per operation; low exploit risk since 1 yocto still prevents cross-contract calls
MED-05 Groups HashSet → NEAR UnorderedSet Requires contract state migration strategy
MED-16 Docker SHA pinning Requires looking up exact digest for the base image; added TODO
Redis authentication for relayer cache External infrastructure change
Sliding window rate limiting (credit) Current fixed-window approach works; sliding window is an optimization
vault_wipe removal from Rhai Function lives in external herolib_vault crate
Integration tests for callback rollback paths Requires NEAR sandbox test harness setup

Test plan

  • cargo check passes
  • All 7 modified contracts compile for wasm32
  • cargo test — 95 passed, 0 failed
  • Manual testing of credit deposit/withdraw/spend flow on devnet
  • Manual testing of DNS claim_refund callback rollback
  • Manual testing of faucet relayer access control
  • Review by team for contract migration implications (faucet state, hosting state)

CI status: 2/3 passing

  • Test / build-and-test (push): pass
  • Test / build-and-test (pull_request): pass
  • Bootstrap Test (pull_request): fail — pre-existing issue, not caused by this PR

The bootstrap failure is because the zinit download URL on development's workflow returns 404 (forge.ourworld.tf/api/packages/geomind_code/generic/zinit/dev/zinit-linux-amd64). This PR includes a fix (commit e8538dd) that switches to a working install source, but Forgejo uses the base branch's workflow file for pull_request events — so the fix only takes effect after merge.

Also fixed in this PR: removed broken geomind_dev_docs gitlink (registered as submodule with no .gitmodules entry) and scoped bootstrap triggers to development/main only (was branches: ["*"]).

Bootstrap has never passed on any branch (checked full history).
The zinit binary package at forge.ourworld.tf/api/packages/geomind_code/generic/zinit/dev
does not exist. Disabling until the package is published.

Re-enable by renaming bootstrap.yaml.disabled back to bootstrap.yaml.

Bootstrap workflow note

The bootstrap workflow is disabled in this PR because zinit binaries were never published to the Forge package registry. The build-linux CI on zinit has a bug (missing musl target).

Fix is in zinit PR #20. Once that's merged, the zinit packages will be published automatically, and the bootstrap workflow here can be re-enabled.

@thabeta yes of course. One thing, Scott did a lot of changes since then, so it seems this PR is outdated. Checking to go against the current development so we have the latest state.

Closing this PR.

Why: The development branch diverged significantly after this PR was opened — ~50 commits landed the same day, including an architectural shift (relayer → gateway). By the time the conflict was flagged, roughly half the original 28 fixes had been independently resolved on development, and the CORS fix (MED-03) needed to be retargeted from the deleted relayer.rs to the new src/gateway/mod.rs.

Rather than resolving conflicts against a codebase that has moved this far, we ran a fresh security audit against the current development HEAD. The new audit (SECURITY_AUDIT_V3.md) covers 71 findings (10 Critical, 20 High, 23 Medium, 18 Low) across all areas — contracts, gateway, SDK/CLI, Rhai engine, and infrastructure — including new attack surface in the gateway, email verification, and identity systems that did not exist at the time of the V2 audit.

A new issue and PR will be opened based on the V3 audit. All V2 findings that are still open are carried forward with updated IDs in V3.
