- compute_run_id() for deterministic run identification
- /assets/by-run-id/{run_id} endpoint for L1 recovery
- Store run_id in provenance when recording runs

Provenance records are now stored on IPFS before the DB transaction.
The provenance CID is included in both:
- The provenance stored in the asset record
- The ActivityPub activity object
This enables:
- Immutable, content-addressed provenance
- Bitcoin timestamping of provenance for cross-L2 dispute resolution
- Verifiable chain of custody: inputs → recipe → output
Provenance structure on IPFS:
{
"inputs": [...],
"output": {"content_hash": "...", "ipfs_cid": "..."},
"recipe": {...},
"recipe_cid": "Qm...",
"provenance_cid": "Qm...", // self-reference for verification
...
}

- Handle 404 explicitly with clear "not found" message
- Log actual response body when JSON parsing fails
- Include status code and body preview in error messages
This helps diagnose issues like empty responses or HTML error pages from L1.

Added logging throughout record_run, publish_cache, and _register_asset_impl:
- Log start of each operation with key parameters
- Log L1 fetch operations and their results
- Log IPFS pin operations
- Log DB transaction start and completion
- Log errors with context
- Log successful completion
This makes it easier to diagnose timeout and other issues.

Wrap synchronous requests.get() and ipfs_client calls in
asyncio.to_thread() to prevent blocking the FastAPI event loop.
This fixes web UI slowness during publishing operations.
- record_run: L1 fetches and IPFS operations now async
- _register_asset_impl: IPFS pin now async
- publish_cache: IPFS pin now async
- get_anchor_tree: IPFS get_bytes now async
- verify_activity_anchor: IPFS get_bytes now async

Implements merkle tree anchoring for ActivityPub activities with
provable Bitcoin timestamps. Activities are batched into merkle trees,
submitted to OpenTimestamps (free), and proofs stored on IPFS.
Key features:
- Merkle tree construction with membership proofs
- OpenTimestamps integration for Bitcoin anchoring
- JSONL backup file on persistent volume (survives DB wipes)
- API endpoints for creating/verifying anchors

The db now returns datetime objects instead of strings in some cases.
Added format_date() helper function that handles both datetime and string
values, and replaced all [:10] date slicing with calls to this helper.

All publishing operations now use three-phase atomic approach:
1. Phase 1: Preparation - validate inputs, gather IPFS CIDs
2. Phase 2: IPFS operations - pin all content before any DB changes
3. Phase 3: DB transaction - all-or-nothing database commits
Changes:
ipfs_client.py:
- Add IPFSError exception class
- Add add_bytes() to store content on IPFS
- Add add_json() to store JSON documents on IPFS
- Add pin_or_raise() for synchronous pinning with error handling
db.py:
- Add transaction() context manager for atomic DB operations
- Add create_asset_tx() for transactional asset creation
- Add create_activity_tx() for transactional activity creation
- Add get_asset_by_hash_tx() for lookup within transactions
- Add asset_exists_by_name_tx() for existence check within transactions
server.py:
- Rewrite record_run:
- Check L2 first for inputs, fall back to L1
- Store recipe JSON on IPFS with CID in provenance
- Auto-register input assets if not already on L2
- All operations atomic
- Rewrite publish_cache:
- IPFS CID now required
- Synchronous pinning before DB commit
- Transaction for asset + activity
- Rewrite _register_asset_impl:
- IPFS CID now required
- Synchronous pinning before DB commit
- Transaction for asset + activity

IPFS pinning can take a long time if content needs to be fetched
from the network. Changed all pin operations to run in background
threads so they don't block the HTTP response.
This fixes the 30s timeout issue when publishing assets.

Fetch media_type and ipfs_cid from L1's cache endpoint instead of
hardcoding asset_type to "video". This fixes images being incorrectly
displayed as videos.

Use 'or {}' pattern to handle both missing keys and explicit None
values for origin, provenance, and metadata fields.

- Add IPFS container to docker-compose
- Add ipfshttpclient dependency
- Add ipfs_client.py module for IPFS operations
- Add ipfs_cid field to Asset model and database schema
- Pin content on L2 IPFS when assets are published/registered
L2 now stores content on its own IPFS node, enabling
federation - content remains available even if L1 goes down.

- Add COOKIE_DOMAIN env var (e.g., ".rose-ash.com")
- Auto-derive from ARTDAG_DOMAIN if not set (strips first subdomain)
- Set domain on auth cookies for sharing across L1/L2 subdomains
- Add secure=True for cross-subdomain cookies
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
L1 needs to know which L2 server issued the token so it can verify
the token with the correct server. Now tokens include:
- l2_server: The L2 server URL (e.g., https://artdag.rose-ash.com)
- username: Also include username for compatibility (in addition to sub)
