1. Client-side SHA-256 in drop box: browser computes and displays
file fingerprints via SubtleCrypto before upload. Receipt codes
are HMAC-derived from file hash so source can verify
correspondence. Source sees hash before submitting.
2. Drop box token persistence: replaced in-memory dict with SQLite
(dropbox.db). Tokens and receipts survive server restarts.
Receipt verification now returns filename, SHA-256, and timestamp.
3. RFC 3161 trusted timestamps + manual anchors: new
federation/anchors.py with get_chain_head_anchor(),
submit_rfc3161(), save_anchor(), and manual export format.
CLI: `soosef chain anchor [--tsa URL]`. A single anchor
implicitly timestamps every preceding chain record.
4. Derived work lineage: attestation metadata supports
derived_from (parent record ID) and derivation_type
(crop, redact, brightness, etc.) for tracking edits
through the chain of custody.
5. Self-contained evidence package: new soosef.evidence module
with export_evidence_package() producing a ZIP with images,
attestation records, chain data, public key, standalone
verify.py script, and README.
6. Cold archive export: new soosef.archive module with
export_cold_archive() bundling chain.bin, verisoo log,
LMDB index, keys, anchors, trusted keys, ALGORITHMS.txt
documenting all crypto, and verification instructions.
Designed for OAIS (ISO 14721) alignment.

Resolves the tension between steganography (strip everything to
protect sources) and attestation (preserve evidence of provenance):
- New soosef.metadata module with extract_and_classify() and
extract_strip_pipeline() — classifies EXIF fields as evidentiary
(GPS, timestamp — valuable for proving provenance) vs dangerous
(device serial, firmware — could identify the source)
- Drop box now uses extract-then-strip: attests ORIGINAL bytes (hash
matches what source submitted), extracts evidentiary EXIF into
attestation metadata, strips dangerous fields, stores clean copy
- Attest route gains strip_device option: when enabled, includes
GPS/timestamp in attestation but excludes device serial/firmware
- Stego encode unchanged: still strips all metadata from carriers
(correct for steganography threat model)
The key insight: for stego, the carrier is a vessel (strip everything).
For attestation, EXIF is the evidence (extract, classify, preserve
selectively). Both hashes (original + stripped) are recorded so the
relationship between raw submission and stored copy is provable.

1. Source drop box: token-gated anonymous upload with auto-attestation,
EXIF stripping, receipt codes, and self-destructing URLs. New
/dropbox blueprint with admin panel for token management. CSRF
exempted for source-facing upload routes.
2. Investigation namespaces: attestation records tagged with
investigation label via metadata. Log view filters by investigation
with dropdown. Supports long-running multi-story workflows.
3. Scale fixes: replaced O(n) full-scan perceptual hash search with
LMDB find_similar_images() index lookup. Added incremental chain
verification (verify_incremental) with last_verified_index
checkpoint in ChainState.
4. Deep forensic purge: killswitch now scrubs __pycache__, pip
dist-info, pip cache, and shell history entries containing 'soosef'.
Runs before package uninstall for maximum trace removal.
5. Cross-org federation: new federation/exchange.py with
export_attestation_bundle() and import_attestation_bundle().
Bundles are self-authenticating JSON with investigation filter.
Import validates against trust store fingerprints.
6. Wrong-key diagnostics: enhanced decrypt error messages include
current channel key fingerprint hint. New carrier_tracker.py
tracks carrier SHA-256 hashes and warns on reuse (statistical
analysis risk).
7. Selective disclosure: ChainStore.selective_disclosure() produces
proof bundles with full selected records + hash-only redacted
records + complete hash chain for linkage verification. New
`soosef chain disclose -i 0,5,10 -o proof.json` CLI command
for court-ordered evidence production.

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.

The stego examples used nonexistent -i flags. Replace with actual
CLI syntax: positional CARRIER argument, -r/--reference for shared
photo, -m/--message for text, -f/--file for file payload. Add
comprehensive examples covering encode, decode, dry-run, DCT mode,
audio stego, credential generation, and channel key management.
Also fix attest examples to match actual CLI commands.

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).

The audit.jsonl file (containing usernames, actions, timestamps) was
not included in the PurgeScope.ALL destruction steps. An adversary
with filesystem access after a failed or partial purge could recover
operational evidence. Added destroy_audit_log step after temp files,
before config deletion.

- 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

The healthcheck tried HTTPS first (curl -fsk https://...) when HTTPS
was disabled. The TLS ClientHello to a plain HTTP listener hung the
sync worker indefinitely. With 2 workers, both got stuck, blocking
all real HTTP requests.
Fix: try HTTP first, add --max-time 3 to release quickly on failure.
Compose override uses HTTP-only to match HTTPS_ENABLED=false default.
