1. Transport-aware stego encoding: --transport flag (whatsapp/signal/
telegram/discord/email/direct) auto-selects DCT mode, pre-resizes
carrier to platform max dimension, prevents payload destruction
by messaging app recompression.
2. Standalone verification bundle: chain export ZIP now includes
verify_chain.py (zero-dep verification script) and README.txt
with instructions for courts and fact-checkers.
3. Channel-key-only export/import: export_channel_key() and
import_channel_key() with Argon2id encryption (64MB, lighter
than full bundle). channel_key_to_qr_data() for in-person
QR code exchange between collaborators.
4. Duress/cover mode: configurable SSL cert CN via cover_name
config (defaults to "localhost" instead of "SooSeF Local").
SOOSEF_DATA_DIR already supports directory renaming. Killswitch
PurgeScope.ALL now self-uninstalls the pip package.
5. Identity recovery from chain: find_signer_pubkey() searches chain
by fingerprint prefix. append_key_recovery() creates a recovery
record signed by new key with old fingerprint + cosigner list.
verify_chain() accepts recovery records.
6. Batch verification: /verify/batch web endpoint accepts multiple
files, returns per-file status (verified/unverified/error) with
exact vs perceptual match breakdown.
7. Chain position proof in receipt: verification receipts (now
schema v3) include chain_proof with chain_id, chain_index,
prev_hash, and record_hash for court admissibility.

Unauthenticated endpoint that reports what's installed, what's
missing, and what's degraded — without exposing secrets or key
material. Reports:
- Module status (stegasoo, verisoo) with versions
- Optional capabilities: DCT, audio, video stego, LMDB, imagehash,
USB monitoring, GPIO — each with actionable install hints
- Key existence (identity, channel, trusted count, backup status)
- Fieldkit status (killswitch, deadman, chain enabled)
- System info (Python version, platform, available memory)
Overall status is "ok" when core modules + keys are present,
"degraded" otherwise. Memory reporting helps diagnose Argon2
OOM issues on constrained hardware (RPi).

- Fix 3 missing CSRF tokens on admin user delete/reset and account
key delete forms (were broken — CSRFProtect rejected submissions)
- Fix trust store path traversal: untrust_key() now validates
fingerprint format ([0-9a-f]{32}) and checks resolved path
- Fix chain key rotation: old key is now revoked after rotation
record, preventing compromised old keys from appending records
- Fix SSRF in deadman webhook: block private/internal IP targets
- Fix logout CSRF: /logout is now POST-only with CSRF token,
preventing cross-site forced logout via img tags

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
3.13 AST parsing issues with Python 3.12 container.

Templates referenced 'admin_user_new' (stegasoo convention) but the
soosef route is named 'admin_new_user'. Caused 500 error when clicking
"Add User" from admin panel.

New file stego_routes.py:
- register_stego_routes() mounts all encode/decode routes on the Flask app
- Async encode with ThreadPoolExecutor + progress polling
- Subprocess isolation for crash-safe stegasoo operations
- Image + audio encode/decode with full validation
- Encode result display with download
- Tools API routes (capacity, EXIF, rotate, compress, convert)
- About page with crypto documentation
Real templates (replacing stubs):
- encode.html (889 lines): full form with carrier upload, passphrase,
PIN, RSA key, embed mode selection, async progress bar
- decode.html (681 lines): decode form with credential inputs
- encode_result.html (242 lines): result display with download
- about.html (602 lines): security documentation
All routes verified working with auth flow.

- Copy Bootstrap 5, Bootstrap Icons, and html5-qrcode from stegasoo
- Fix stegasoo CLI import (cli group, not main wrapper)
- Add .gitignore and README.md
- Verified: soosef init, soosef serve, all routes, key export/import all work
