Bottleneck 1: ImageHashes generalization
- phash and dhash now default to "" (optional), enabling attestation
of CSV datasets, sensor logs, documents, and any non-image file
- Added ImageHashes.from_file() for arbitrary file attestation
(SHA-256 only, no perceptual hashes)
- Added ImageHashes.is_image property to check if perceptual matching
is meaningful
- Added content_type field to AttestationRecord ("image", "document",
"data", "audio", "video") — backward compatible, defaults to "image"
- from_dict() now tolerates missing phash/dhash fields
Bottleneck 2: Lazy path resolution
- Converted 5 modules from eager top-level path imports to lazy
access via `import soosef.paths as _paths`:
config.py, deadman.py, usb_monitor.py, tamper.py, anchors.py
- Paths now resolve at use-time, not import-time, so --data-dir
and SOOSEF_DATA_DIR overrides propagate correctly to all modules
- Enables portable mode (run entirely from USB stick)
- Updated deadman enforcement tests for new path access pattern
Bottleneck 3: Delivery acknowledgment chain records
- New CONTENT_TYPE_DELIVERY_ACK = "soosef/delivery-ack-v1"
- ChainStore.append_delivery_ack() records bundle receipt with
sender fingerprint and record count
- import_attestation_bundle() auto-generates ack when chain store
and private key are provided
- Enables two-way federation handshakes (art provenance, legal
chain of custody, multi-org evidence exchange)

Critical:
- FR-01: Chain verification now supports key rotation via signed rotation
records (soosef/key-rotation-v1 content type). Old single-signer
invariant replaced with authorized-signers set.
- FR-02: Carrier images stripped of EXIF metadata by default before
steganographic encoding (strip_metadata=True). Prevents source
location/device leakage.
High priority:
- FR-03: Session timeout (default 15min) + secure cookie flags
(HttpOnly, SameSite=Strict, Secure when HTTPS)
- FR-04: CSRF protection via Flask-WTF on all POST forms. Killswitch
now requires password re-authentication.
- FR-05: Collaborator trust store — trust_key(), get_trusted_keys(),
resolve_attestor_name(), untrust_key() in KeystoreManager.
- FR-06: Production WSGI server (Waitress) by default, Flask dev
server only with --debug flag.
- FR-07: Dead man's switch sends warning during grace period via
local file + optional webhook before auto-purge.
Medium:
- FR-08: Geofence get_current_location() via gpsd for --here support.
- FR-09: Batch attestation endpoint (/attest/batch) with SHA-256
dedup and per-file status reporting.
- FR-10: Key backup tracking with last_backup_info() and
is_backup_overdue() + backup_reminder_days config.
- FR-11: Verification receipts signed with instance Ed25519 key
(schema_version bumped to 2).
- FR-12: Login rate limiting with configurable lockout (5 attempts,
15 min default).
Nice-to-have:
- FR-13: Unified `soosef status` pre-flight command showing identity,
channel key, deadman, geofence, chain, and backup status.
- FR-14: `soosef chain export` produces ZIP with JSON manifest,
public key, and raw chain.bin for legal discovery.
Tests: 157 passed, 1 skipped, 1 pre-existing flaky test.

Merge stegasoo (v4.3.0, steganography) and verisoo (v0.1.0, attestation)
as subpackages under soosef.stegasoo and soosef.verisoo. This eliminates
cross-repo coordination and enables atomic changes across the full stack.
- Copy stegasoo (34 modules) and verisoo (15 modules) into src/soosef/
- Convert all verisoo absolute imports to relative imports
- Rewire ~50 import sites across soosef code (cli, web, keystore, tests)
- Replace stegasoo/verisoo pip deps with inlined code + pip extras
(stego-dct, stego-audio, attest, web, api, cli, fieldkit, all, dev)
- Add _availability.py for runtime feature detection
- Add unified FastAPI mount point at soosef.api
- Copy and adapt tests from both repos (155 pass, 1 skip)
- Drop standalone CLI/web frontends; keep FastAPI as optional modules
- Both source repos tagged pre-monorepo-consolidation on GitHub

Reformat 8 files and add --target-version py312 to avoid
