- Switch frontend Dockerfiles to pnpm via corepack (project uses pnpm-lock.yaml)
- Pin SurrealDB to v3.0.5 and switch datastore URL from `file:` to `rocksdb:`
- Add idempotent SurrealDB schema bootstrap on connect to prevent NotFoundError on first SELECT against schemaless tables in 3.x
Crystal's compiler warns when an overriding method's parameter name
differs from the parent's, since named-argument callers would pass
the wrong slot. Underscore-prefix was meant as 'unused' but it changed
the parameter name, which Crystal correctly flagged.
Match the parent signature (s : Domain::NewSecret) and use the explicit
'_ = s' idiom inside the body to mark it intentionally unused. Now
'shards build cre' compiles with zero warnings.
Two changes that go together:
1. RotationWorker (src/cre/engine/rotation_worker.cr) is the missing
subscriber that turns RotationScheduled events into actual 4-step
rotations. Without it, the daemon ticked, evaluated, fired
RotationScheduled, and... nothing happened. Now it dispatches via
the orchestrator using a kind -> Rotator dispatch table populated
at boot.
2. cre run now wires:
- All 4 rotators based on env vars (AWS_ACCESS_KEY_ID, VAULT_ADDR/TOKEN,
GITHUB_TOKEN). EnvFile is always available.
- Telegram subscriber + bot if TELEGRAM_TOKEN + chat-id env vars set.
Boot output reports which rotators wired and whether telegram is on.
3. CONFIGURATION.md: full operator setup guide. 13 sections covering
required env vars, Postgres setup with role hardening, key generation,
policy authoring, inventory seeding (per-rotator tag schemas), AWS IAM
policy, Vault token policy.hcl, GitHub admin PAT acquisition, Telegram
bot creation + chat ID discovery, systemd unit with hardening
directives, audit chain verification, KEK rotation procedure, and a
13-item production security checklist.
Walks through the full flow — passkey registration, passkey login,
new conversation lookup, empty thread, first message, end-to-end
chat, and mobile view — matching the format used by the bug-bounty
and SIEM project demos.
cre tui-demo (8 seconds default) renders the live TUI with synthetic
events: 4 fake credentials going through rotation states, a policy
violation, drift detection, an apply-step failure, and a critical alert.
Lets you see what watch mode looks like without seeding any real data.
demo-full: dropped the bogus --config=... flag (cre run never
implemented config-file loading; uses env vars + --db). Now exports
the four service URLs (DATABASE_URL, AWS_ENDPOINT, VAULT_ADDR,
GITHUB_API_BASE) at the user's manually-set ports (6022/45666/18201/7115)
and runs the daemon against the real Postgres. Added demo-full-status
to peek at container health.
Justfile mirrors the haskell-reverse-proxy pattern (grouped recipes:
build, run, demo, test, quality, db, util). 33 recipes covering full
lifecycle - including parameterized recipes (cre rotate ID, cre policy
show NAME) that read more naturally as 'just rotate ...' than as
make targets.
User-edited docker-compose.yml port mappings preserved
(postgres:18 on 6022, localstack on 45666, vault on 18201,
fake-github on 7115).
Nim package names cannot contain hyphens, so `nimble install -y nph`
in the lint workflow aborted on `validatePackageName` before nph could
be installed, causing the Nim lint job to fail with `nph: command not
found`. Renaming the manifest to match the binary name resolves it
and lets contributors run nimble inside the project.
Tier 1 demo was creating an AuditLog instance but never subscribing it
to the bus, so the verification step always reported '0 events'.
Now we explicitly start the AuditSubscriber and the verifier reports
the actual chain length (4 step events + RotationCompleted = 5).
Tier 1 (cre demo): in-memory SQLite + tempfile .env rotator. Walks
through inventory -> before -> 4-step rotation -> after -> audit chain
verify. Narrates every step event live with green/red glyphs. Runs in
under 1 second on commodity hardware, no external deps.
Tier 2 (docker/docker-compose.yml): postgres:16, localstack
(secretsmanager), hashicorp/vault dev mode, plus a fake-GitHub Flask
app that mocks /user, POST/DELETE /user/personal-access-tokens.
config/demo-full.cr.example documents env vars for the full stack.
Also fixed env_file rotator newline preservation (lines(chomp: true)
+ explicit \n join) so the rotated file is properly delimited.
Stack:
- Ansi: stdlib-only escape helpers (move, colorize, strip)
- State: rolling view of active rotations + recent events; trims to N
- Renderer: paints header / status / active / recent panels; works against
any IO so tests assert against IO::Memory
- Tui: ties State + Renderer to event bus; coalesces repaints to a tick
interval (default 200ms) to avoid flicker under burst events
Active rotation rows show step progress as a filled-bar (▰▰▰▱). Recent
events list latest 8 with timestamp + severity glyph (✓ / ⚠ / !). The
renderer's pad/center helpers correctly account for ANSI escape widths
when computing visible column width.
9 specs cover ANSI helpers (color codes, cursor move, strip), State
event-to-row mapping with completion bookkeeping and ring-buffer trim,
and Renderer output assertions across empty + active + populated states.
LogNotifier subscribes (Drop overflow) and emits stdlib Log lines with
structured kwargs (credential_id, rotation_id, severity, etc.) suitable
for downstream ingestion by journald/vector/fluentd.
Telegram is a thin HTTP::Client wrapper for sendMessage and getUpdates.
TelegramSubscriber sends emoji-prefixed alerts on RotationFailed,
DriftDetected, PolicyViolation, AlertRaised; success notifications gated
by the notify_on_success flag. Errors are swallowed so a flaky bot never
blocks the engine.
TelegramBot does long-polling getUpdates and dispatches commands:
- viewer tier: /status /queue /history /alerts /help
- operator tier: viewer + /rotate + /snooze
ACL is by chat_id allowlist (bot token + chat IDs in env vars).
/rotate publishes RotationScheduled to the bus.
11 unit specs cover send_message + error handling + getUpdates parsing,
subscriber dispatch, success-suppression flag, and bot ACL enforcement
(unauthorized / viewer-blocked-from-mutations / operator-can-rotate).
Initial tick fires immediately on start so first policy evaluation
doesn't wait for the full interval on boot. The PolicyEvaluator
subscribes to SchedulerTick events and invokes evaluate_all -> overdue
discovery -> RotationScheduled fan-out. 3 specs verify boot-tick,
periodic cadence, and clean stop().
Github::Client wraps the bearer-auth REST API with required
'X-GitHub-Api-Version: 2022-11-28' header. Implements me, create_pat
(POST /user/personal-access-tokens), delete_pat (DELETE by id).
GithubPatRotator's 4-step contract:
- generate: create_pat returns new id + token value (fresh PAT alongside old)
- apply: no-op (create_pat already active)
- verify: probe-client uses the NEW PAT to GET /user; success means it works
- commit: delete OLD PAT by id (tracked via old_pat_id tag)
- rollback_apply: delete NEW PAT
7 unit specs verify create/delete/me round-trips, full rotation path,
verify-on-401, and rollback deletion.
- New Aenebris.ML.Middleware module: Wai middleware that wires the
Aenebris.ML.Engine into the per-request pipeline. Per request:
1. Run extractFeatures (FeatureContext + Request) -> FeatureVector
2. Convert via featureVectorToVector -> VU.Vector Double
3. runEngine eng fv -> DecisionDetails
4. Route by ddDecision:
DecisionHuman -> pass through to inner Application,
optionally attach X-Aenebris-ML-Decision
and X-Aenebris-ML-Score response headers
DecisionBot -> 403 + text/plain block body
DecisionChallenge -> 403 + text/html challenge page
All response builders are operator-overridable via the
MLMiddlewareConfig record. Optional logging callback fires once
per request for structured logs / metrics integration.
- defaultBotResponse, defaultChallengeResponse: sensible defaults
matching the existing WAF middleware pattern (403 + descriptive
body). decisionResponseHeader / scoreResponseHeader are exported
so operators can build custom responses that still surface the
signal headers.
- 12 tests via Network.Wai.Test.runSession covering: pass-through
on Human, 403 on Bot, 403 on Challenge with text/html body,
signal-header attachment toggle, custom response builder override,
logging callback invocation count.
- aenebris.cabal: expose Aenebris.ML.Middleware in the library stanza.
- test/Spec.hs: add modifyTVar' to the Control.Concurrent.STM import
list for the logging-callback test.
- 354 total examples passing, 0 GHC warnings on the new module.
This closes the core Phase 2.5 ML pipeline. The full sequence
(Features -> Model -> Loader -> Inference -> Calibration -> IForest
-> Engine -> Middleware) is now fully implemented and integration-
tested. A hosted Aenebris instance can now be configured with a
trained LightGBM model + optional calibrator + optional IForest
and will block bots, challenge ambiguous traffic, and pass humans
on every HTTP request.
Rotator base exposes the four lifecycle methods as abstract; subclasses
register at compile time via 'register_as :kind' macro. REGISTRY is
populated as soon as the rotator file is required - drop a new file in
src/cre/rotators/ and the orchestrator can dispatch to it.
EnvFileRotator implements the simplest rotation:
- generate: 32 random bytes -> base64-urlsafe (no padding)
- apply: write to PATH.pending atomically (in-place line replace, 0600)
- verify: parse pending file, confirm key=value present and non-empty
- commit: rename PATH.pending -> PATH (atomic on POSIX)
- rollback_apply: unlink PATH.pending
RotationOrchestrator runs the 4-step contract with full event publishing,
state machine transitions in DB (generating -> applying -> verifying ->
committing -> completed | failed), and rollback_apply on apply/verify
failure. 8 specs cover happy path + raised-during-apply + rollback verification.
- Policy struct: matcher Proc, max_age, warn_at, enforce_action, notify_channels, triggers
- Builder validates all required fields at .build, raises BuilderError with the policy name
- DSL exposes top-level 'policy' method via 'with builder yield' so all
builder methods (description, match, max_age, enforce, notify_via, etc.)
are receiver-less inside the block
- Symbol literals autocast to Action/Channel/Trigger enums on direct calls;
Symbol overload for splat parameters (notify_via :telegram, :email)
- Evaluator subscribes to bus, fires PolicyViolation + RotationScheduled
(rotate_immediately) or AlertRaised (notify_only/quarantine) when overdue
- 15 unit specs cover Policy.matches?/overdue?/in_warning_window?,
Builder validation, DSL syntax with closures, evaluator action dispatch
- New Aenebris.ML.Engine module: pure decision pipeline composing
the previously-built Loader, Inference, Calibration, and IForest
modules into a single per-request scoring path.
Engine record holds (Ensemble, Calibrator, Maybe IForest,
EngineConfig); runEngine takes a feature vector and produces
DecisionDetails (Decision, raw proba, calibrated proba, optional
IForest score). The Decision is one of DecisionHuman, DecisionBot,
or DecisionChallenge.
- Implements the escalation-gate semantics per the 2026 research
correction (over the deprecated 0.8/0.2 weighted blend):
calibrated <= humanThreshold -> DecisionHuman
calibrated >= botThreshold -> DecisionBot
otherwise (ambiguous band):
if IForest configured and ifScore >= escalation threshold
-> DecisionBot (escalation)
else if challenges enabled
-> DecisionChallenge
else
-> DecisionHuman (fallthrough)
Defaults: 0.3 / 0.7 thresholds, 0.6 IForest escalation, challenges
on by default.
- 17 tests covering: defaultEngineConfig values, decision boundaries
with NoCalibrator and no IForest (low/mid/high leaf ensembles),
ambiguous-band escalation via low-vs-high anomaly IForests,
ambiguous-band with challenges disabled (fallthrough to Human or
escalation to Bot), Platt calibrator pulling decisions across
thresholds, and DecisionDetails field correctness.
- aenebris.cabal: expose Aenebris.ML.Engine in the library stanza.
- 342 total examples passing, 0 GHC warnings on the new module.
The Wai middleware wiring (extract features -> runEngine -> route by
Decision) is the next module (ML.Middleware); Engine intentionally
stays pure / independent of HTTP machinery so it can be unit-tested
without request fixtures.
Events form a Crystal class hierarchy so subscribers pattern-match
exhaustively. EventBus delivers to subscribers via Crystal channels with
per-subscriber overflow policy (Block for audit, Drop for best-effort).
AuditSubscriber listens for all rotation/policy/drift/alert events and
serializes them into the hash-chained audit log via AuditLog.append.
Engine wires Persistence + AuditLog + AuditSubscriber + EventBus together
so callers just .start/.stop. 7 unit specs verify boot, fanout to N
subscribers, drop-on-overflow semantics, and end-to-end event -> audit row.
Three layers of integrity:
- Hash chain (SHA-256 chained) catches silent edits
- HMAC ratchet rotates keys every N entries with HKDF-style derivation
and zeroizes old key bytes from memory
- Merkle batch sealing builds tree over content_hashes, signs root
with Ed25519 (FFI to libcrypto EVP_PKEY_ED25519 directly since stdlib
lacks the high-level OpenSSL::PKey wrapper)
AuditLog.append is mutex-guarded for serial writes; verify_chain detects
both single-row tampering and structural inconsistency. BatchSealer's
pack_message format (BE start_seq || BE end_seq || merkle_root) is shared
between signer and verifier so external auditors can validate offline.
- Random with constant-time-equal helper
- KEK loader from env (Tier 1) with InvalidKekError on bad/missing var
- AEAD via direct LibCrypto FFI bindings (Crystal 1.20 stdlib OpenSSL::Cipher
doesn't expose GCM auth_data/auth_tag, so we extend LibCrypto with
EVP_CIPHER_CTX_ctrl + EVP_aes_256_gcm and call them directly)
- Envelope: per-row DEK wrapped by KEK, AAD-bound, algorithm_id reserved
for crypto agility (0x01 = AES-256-GCM today, 0x02/0x03 reserved)
- 17 unit specs including a 100-iteration random property test
- Tag-tampered ciphertext / wrong-AAD / wrong-key all raise Aead::Error
- New Aenebris.ML.IForest module: pure Isolation Forest scorer
implementing the Liu et al. 2008 ICDM formula
anomaly_score = 2^(-E[h(x)] / c(n))
where E[h(x)] is the average path length across iTrees and
c(n) = 2*H(n-1) - 2(n-1)/n (expected unsuccessful BST search depth).
ITree ADT (ITreeLeaf size | ITreeSplit featIdx threshold left right)
with leaf-size c(n) correction added to traversal depth at every
leaf, matching the original paper. Score-only mode (accept pre-
trained forests from Python sklearn or similar); fitting is deferred
to a later phase. Default constants from Liu et al.: 100 trees,
256 subsample size, max depth ceil(log2(256)) = 8.
- 24 tests covering: harmonicNumber edge cases (H(0), H(1), H(2),
H(3), large-n asymptotic), normalizationConstant for n in {0, 1,
2, 256}, single-split and deep-tree path length traversal,
scoreIForest edge cases (empty forest, subsample 0, subsample 1),
shorter-path-equals-higher-score invariant, default constants,
Euler-Mascheroni precision.
- aenebris.cabal: expose Aenebris.ML.IForest in the library stanza.
- test/Spec.hs: import Expectation explicitly from Test.Hspec for the
shouldBeApprox helper.
- 325 total examples passing, 0 GHC warnings on the new module.
The escalation-gate composition with the calibrated GBDT score
(per docs/research/phase-2.5-ml-synthesis.md correction over the
0.8/0.2 folk-wisdom blend) is intentionally NOT in this module --
it belongs in the downstream ML.Engine module that wires Loader +
Inference + Calibration + IForest into a single decision pipeline.
- All 4 repos mirror the SQLite contracts using PG-native types
(UUID, BYTEA, JSONB, BIGSERIAL, TIMESTAMPTZ, SMALLINT)
- audit_no_modify() trigger refuses UPDATE/DELETE/TRUNCATE on audit_events
- pg_advisory_xact_lock for cross-process row locking
- Integration tests verify trigger fires correctly on tamper attempt
- Test cleanup helper temporarily disables trigger to reset between specs
- 4 integration specs all green against PostgreSQL 16
All four repos implement their abstract contracts. Migrations create
tables idempotently. Bytes round-trip through SQLite BLOB columns
correctly. RotatorKind and RotationState enums replace Symbol fields
in record types so they round-trip safely through DB string columns.
8 unit specs verify CRUD, find_by_external, in_flight filtering,
revocation, and audit append/range/latest_hash genesis behavior.
- New Aenebris.ML.Inference module: pure tree-walk over the unified Tree
SoA produced by Aenebris.ML.Loader. Mirrors LightGBM C++ NumericalDecision
exactly: NaN remapped to 0 unless MissingType=NaN; MissingType=Zero/NaN
routes via default-left flag; '<=' predicate (not '<'); categorical
bitmap test using cat_boundaries slice; average_output divisor for RF
mode; sigmoid link for binary logistic objective. kZeroThreshold = 1e-35
matches LightGBM's IsZero exactly. Defensive against NaN/Inf/negative
on categorical paths. 35 tests covering leaf-only, numerical splits,
missing-value semantics, categorical routing, multi-tree sums, sigmoid
saturation, average_output, regression vs binary objectives, and
end-to-end against the disk fixture.
- New Aenebris.ML.Calibration module: pure calibration of binary
classifier outputs. Calibrator ADT (NoCalibrator | PlattCalibrator a b
| IsotonicCalibrator bp). Platt scaling uses Newton's method with
damped line search on Platt-1999 smoothed targets (N+ + 1)/(N+ + 2)
and 1/(N- + 2); numerically stable softplus-based log-loss. Isotonic
regression uses Pool Adjacent Violators on a stack with tie pre-
grouping, sorted (raw, calibrated) breakpoints, linear interpolation,
out-of-range clamping. Sub-2-sample input returns NoCalibrator. 28
tests covering all three calibrator constructors, fit edge cases,
Platt convergence on logistic data, isotonic correction of non-
monotone data, tie handling, all-same-label degenerate cases, and
lookup behavior including clamping and interpolation.
- aenebris.cabal: expose both new modules in the library stanza.
- 301 total examples passing, 0 GHC warnings on either new module.
- shard.yml with db, pg, sqlite3, tourmaline (deps), webmock (dev)
- Makefile with build/test/format/lint/demo targets
- .gitignore, .editorconfig, LICENSE (MIT), README skeleton
- ameba lint deferred until libpcre3-dev is available on this env
- New Aenebris.ML.Loader module: pure ByteString -> Either ParseError Ensemble
parser for LightGBM v4 plain-text models. Header / tree-blocks / trailing-
section state machine; converts split-arrays + leaf-arrays into the unified
Tree SoA via unifyChild + complement; rejects non-v4, multi-class, and
is_linear=1; extracts embedded sigmoid scale and bare average_output flag;
runs validateEnsemble before returning.
- Frozen test fixtures under test/fixtures/ml/ (tiny_lgbm_v4.txt,
stump_lgbm_v4.txt) hand-crafted from the v4 spec annotated example. CI runs
against these with zero Python dependency.
- scripts/regen_lgbm_fixture.py: uv-runnable PEP 723 script that retrains a
tiny binary GBDT and writes to a separate
test/fixtures/ml/regen_sample_v4.txt so the frozen fixtures stay pristine.
- 30 new mlLoaderSpec tests covering happy path, header rejection, sigmoid
extraction, average_output, tree-level rejection, feature_names with '=',
and ParseError reporting. 238 total examples passing, 0 GHC warnings on
Loader.
