…lar [CT-01]
Implements the previously stubbed submit_document handler in
contract/src/lib.rs and adds anchor_hash() to StellarClient in
contract/src/stellar.rs.
Changes:
- contract/src/stellar.rs:
- Added AnchorResult struct (tx_hash, ledger, anchored_at)
- Implemented StellarClient::anchor_hash() using stellar-base:
- Fetches account sequence number from Horizon
- Builds a ManageData operation with key 'doc_' + hash[:58]
(matches NestJS buildDataKey() exactly)
- Signs the transaction with the service's STELLAR_SECRET_KEY
- Submits to Horizon via application/x-www-form-urlencoded
- Returns AnchorResult on success; propagates Horizon error detail on failure
- Added build_data_key() and build_revocation_key() helpers
- Added stellar-base = "0.5" dependency for XDR/transaction building
- contract/src/lib.rs:
- submit_document() now takes State<AppState> and calls stellar.anchor_hash()
- Idempotency: checks Redis cache (stellar:verify:{hash}) before submitting;
returns existing result with 200 if already anchored
- On success: caches result with 1-year TTL, returns SubmitResponse
- On Horizon failure: returns 502 with error detail
- Returns 400 for missing/malformed hash (unchanged)
- Added Deserialize to SubmitResponse to support cache round-trip
Closes CodeGirlsInc#854

Contracts (Rust): - Run cargo fmt --all to fix formatting in contract/src/lib.rs and contract/src/stellar.rs; long lines in info!/warn! macros and method chains were not wrapped to rustfmt's column limit Frontend (Next.js): - Move misplaced pages from app/(protected)/ to app/[locale]/(protected)/ so they are covered by the root layout at app/[locale]/layout.tsx. Affected pages: admin/providers, profile, reports, settings/api-keys. Without a root layout Next.js 15 refuses to build the page.
…bility stellar-base 0.5.0 calls sodiumoxide::crypto::sign::Signature::from_slice() which does not exist in newer sodiumoxide versions. Pinning to =0.2.6 (the version stellar-base 0.5 was built against) resolves the compile error: error[E0599]: no associated function or constant named 'from_slice' found for struct 'sodiumoxide::crypto::sign::Signature'
