fix(contracts): storage key collisions, NEP-141 compliance, access control ... d306236921

C-07, C-08: Credit LineIndex/ApprovalIndex vectors now use parameterized
StorageKey variants (owner: AccountId, line_id: u64) so each user's
collections get unique trie prefixes — fixes data corruption across users.

H-05: Sporex and Groups replace raw b"x" byte literal prefixes with
BorshStorageKey enum variants — eliminates silent collision risk.

H-07: Credit ft_on_transfer return type changed from String to
PromiseOrValue<U128> per NEP-141 — bad input now gracefully refunds
instead of panicking; fixes M-04 too.

H-08: Hosting and Sporex ft_on_transfer changed from bare U128 to
PromiseOrValue<U128> — NEP-141 standard compliance.

H-09: DNS claim_refund and withdraw_fees now chain .then() callbacks
(on_refund_complete, on_fee_withdraw_complete) to restore state on
failed token transfers — prevents silent fund loss.

H-10: Hosting sla_settle_period restricted to admin only — prevents
SLA forgery by arbitrary callers.

H-11: assert_one_yocto() added to withdraw/spend (credit),
withdraw_usdh/gld/spore (sporex), claim_refund (dns),
sla_stake_withdraw (hosting) — guards against function-call access key
attacks.

H-12: Faucet fund_account now requires caller to be owner or an
authorized relayer — prevents faucet drain by arbitrary callers.
add_relayer/remove_relayer admin methods added.

M-05: Sporex withdrawal callbacks replace .expect() panics with safe
match — prevents permanent state inconsistency on parse failure.

M-06: Marketplace per-slice price uses ceiling division — prevents
rounding to zero causing zero-payment reservations.

M-08: DNS set_records bounded to max 50 records, 255-char keys,
1024-char values — prevents storage exhaustion attacks.

M-09: Groups create_group refunds excess deposit to caller.

L-03: assert!(!env::state_exists()) guard added to #[init] in hosting,
zinit_registry, groups, identity, kvs contracts.

L-04: Marketplace validate_country enforces 2-3 char length.

L-05: Faucet set_drip_amount and set_cooldown reject zero values.

L-06: Faucet withdraw chains an observability callback.

L-07: Faucet total_dispensed counter only incremented in success
callback — prevents stat drift on failed transfers.

L-08: DNS cancel_auction stores refund_amount before cancel() mutates
the auction struct.

fix(sdk/cli/rhai): credential exposure, ABI mismatches, and RCE vectors ... ccbc06a1bc

Security fixes C-01 through C-04, H-02 through H-04, M-01 through M-03,
M-20, L-09, L-11, L-12 from SECURITY_AUDIT_V3 (issue #38):

- C-01: Remove run_command/run_command_output/env_var from Rhai engine (RCE)
- C-02: Redact private_key in Account and ContractBuilder Debug impls
- C-03: Remove private key println statements from CLI cmd.rs
- C-04: Warn when --secret-key/--mnemonic passed as argv (process list visibility)
- H-02: Replace (deposit_near * 1e24) as u128 with near_to_yocto() using
  integer arithmetic to prevent precision loss on large NEAR amounts
- H-03: parse_near returns String (decimal yocto) instead of i64
- H-04: deploy() returns informative message instead of fake tx hash
- M-01: Rename gld_token to spore_token in credit vault
- M-02: spend() adds payee param; args use 'payee'/'memo' keys per contract ABI
- M-03: get_balance uses list_lines + sum instead of non-existent get_balance view
- M-20: Remove unsafe set_var wrapper in Rhai (was UB in multi-threaded context)
- L-09: Redact ValidatorKey secret_key in Debug impl
- L-11: Remove f64 fallback in parse_json_to_u128 (precision loss for u128)
- L-12: Rename bucket_id to line_id in CLI for contract consistency

fix(gateway): CORS, XSS, rate limiting, auth hardening, and input validation ... ae4c31bac0

Security fixes C-09, C-10, H-17, H-19, H-20, M-13 through M-17, M-19,
M-22, M-23, L-16 through L-18 from SECURITY_AUDIT_V3 (issue #38):

- C-09: Restrict CORS to [POST, GET, OPTIONS] + explicit headers allowlist;
  add GATEWAY_CORS_ORIGIN env var for production lockdown; max_age(3600)
- C-10: submitTransaction checks FunctionCall method against write_methods
  whitelist before dispatching to the chain
- H-17: Rate limiter applied to gateway.submitTransaction path
- H-19: HTML-escape account_id/tx_hash/domain in confirmation page (XSS)
- H-20+M-16: reqwest::Client with 15s request / 5s connect timeout
- M-13: Domain validation — length, charset, consecutive hyphens, .hero TLD
- M-14: amount parsed as u128 before forwarding; rejects non-numeric values
- M-15: Pagination limit capped at 100 in all 5 marketplace list methods
- M-17: OsRng replaces thread_rng() for email verification tokens
- M-19: PendingStore GC runs on every insert (not just at capacity)
- M-22: RateLimiter evicts expired entries when HashMap reaches 100k entries
- M-23: SendGrid log sanitized — email masked, body removed from log
- L-16: Auth error messages normalized to generic "Authentication failed"
- L-17: Comment added about built-in methods bypassing middleware
- L-18: Hardcoded faucet drip amount removed from account activation response

fix(infra/ci/docker): key permissions, secrets management, and supply chain ... 75d59bb428

Security fixes C-05, C-06, H-01, H-13 through H-16, M-11, M-12, M-21,
L-13, L-15 from SECURITY_AUDIT_V3 (issue #38):

- C-05: chmod 0600 on all written key files (provision/config, cluster_manager)
- C-06: Gateway secrets written to /etc/hero/gateway.env (mode 0600) instead
  of inline service env vars exposed in process environment
- H-01: All git dependencies pinned to specific rev hashes (no more branch=)
- H-13: RPC node binds to 127.0.0.1 instead of 0.0.0.0 in dev mode
- H-14: Caddy install uses tempfile crate for secure temp dir (no predictable path)
- H-15: CI builder image pinned to @sha256 digest in both workflow files
- H-16: Dockerfile.builder TODO comment for SHA pinning
- M-11: Dockerfile.neard adds non-root 'hero' user, runs CMD as USER hero
- M-12: actions/checkout pinned to commit SHA in both CI workflows
- M-21: validator_key.json permissions checked before reading (warn if group/world readable)
- L-13: heroledger script runner fails fast on first error (no silent failures)
- L-15: heroledgerd default version changed from "master" to "2.4.0"

docs: add SECURITY_AUDIT_V3.md — 71 findings full-codebase audit ... 4a3ccf11ba

Documents all 71 security findings (10 Critical, 20 High, 23 Medium, 18 Low)
from the comprehensive audit of development HEAD 267be5f. Supersedes
SECURITY_AUDIT_V2.md. Referenced by issue #38 and addressed in the
four preceding commits on this branch.

fix(ci): correct builder image digest format to tag@sha256 ... 290632eadd

Use ':2@sha256:...' format instead of '@sha256:...' alone.
The Forgejo runner requires the tag to be present alongside
the digest to resolve the image manifest in the registry.

fix(ci): revert SHA pinning — Forgejo runner does not support digest refs ... 1282e0caf1

The Forgejo Act runner cannot resolve image references with @sha256 digest
or action SHAs (e.g. actions/checkout@<sha>). Both cause 'Set up job' to
fail immediately with no log output. Revert to the working forms while
preserving the digest value as a comment for manual verification.

H-15/M-12: deferred — runner must support OCI digest pinning first.

4a3ccf1	Docs	SECURITY_AUDIT_V3.md

Deferred items

Three items were attempted and reverted due to runner constraints or require separate migration work:

• H-15, M-12 (CI SHA pinning) — Forgejo Act runner does not support image@sha256:digest or action@sha refs; digest values are preserved as comments in the workflow files for manual verification
• H-18 nonce — implemented as optional X-Gateway-Nonce header only (backward-compatible)
• H-06, L-01, L-10, M-07 — architectural/migration work, documented in audit as deferred

Ready for review once WIP is removed.

fix(ci): use upstream zinit install script in bootstrap workflow ... 50bad5e6c7

The Forge-hosted install script downloads from the geomind_code generic
package registry which has no packages published (404). Switch to the
upstream threefoldtech/zinit GitHub install script which downloads from
GitHub Releases where the binaries actually exist.

fix(ci): restore zinit install script and fix zinit_server binary name ... 4872ccee22

The Forge install script downloads from geomind_code generic packages which
are now published (zinit, zinit_server, zinit_pid1 for linux-amd64).
The actual server binary (zinit_http) is published under the name
zinit_server per the install script convention.

Also fix: bootstrap.yaml was calling ~/hero/bin/zinit-server (hyphen) but
the install script places it as ~/hero/bin/zinit_server (underscore).
