From d67fdab99343cec3705ee1e77d08031c0b233cbd Mon Sep 17 00:00:00 2001 From: Rolando Santamaria Maso <4096860+jkyberneees@users.noreply.github.com> Date: Tue, 13 Oct 2026 06:13:57 +0200 Subject: [PATCH 1/4] test(security): on-demand prompt-injection E2E suite and live-model benchmark MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two suites, both gated and never run on CI (CI runs plain go test with neither gate set): ODEK_PI_E2E — proves the RUNTIME blocks an injection even when the model is fully compromised. A mock model that obeys every injected instruction drives the real binary while payloads sit on real ingestion surfaces: a curl-piped-to-shell exfil is denied and a loopback canary stays cold with no secret leak; a ~/.odek trust-anchor write fails closed and leaves no file; http_request to 169.254.169.254 is refused by the dial guard; a planted file arrives inside the per-call untrusted_content_ envelope with a literal close tag neutralised; a pipe-to-shell memory fact is rejected; a hostile AGENTS.md cannot authorize rm -rf. ODEK_PI_BENCH — measures the MODEL against the configured live provider, scoring ingested/complied/blocked/reported/leaked per scenario. It fails a scenario as inconclusive when the payload was never ingested or the model was never reached, so a clean verdict always means the model saw the bait and declined it. Both are validated by negative controls: flipping non_interactive to allow lets an otherwise-blocked local write through, and the bench's compliance detector scores a deliberately complying mock model as complied=true. TestMain keeps the two gates across its env scrub and stashes the pre-redirect home for the benchmark's credential borrow.

Reworked so each case isolates its defense. Runtime suite (ODEK_PI_E2E): - each case runs with the probed class set to allow, and pairs the attack with a benign control that must succeed in the same posture; delete the defense and the attack assertion fails, mask everything and the control assertion fails - assert the denial REASON delivered to the model, not just tool_call_failed (which also fires for bad args or an unknown tool) - trust anchor used a '~' path write_file never expands, so it wrote into the work dir and never reached isProtectedOdekPath; now absolute, with ~/.odek/notes.txt as the non-anchor control - the wrapper assertion was unfalsifiable: the security pillar ships the literal 'untrusted_content_' in the system prompt. Now scoped to the request carrying the marker, anchored on a nonce'd tag, and exercising the real neutraliser via a fullwidth close-tag look-alike - memory: with persistence allowed, a benign fact must land in env.md before the poisoned one is asserted absent — previously both were denied by the persistence gate and FactLooksUnsafe never ran - AGENTS.md case proves the hostile file reached the model's context - per-call event matching (unique tool-call ids) so a benign control is not mistaken for the attack - leak check reads stderr, where odek actually renders the answer Mutation-tested: stubbing isProtectedOdekPath, FactLooksUnsafe or NeutraliseUntrustedLiterals turns the matching test red; restoring it turns it green. Live bench (ODEK_PI_BENCH): - the operator's real secrets.env is no longer written into the fixture that a scenario tells the model to exfiltrate; provider keys go through the environment, the planted file holds only a canary, the real key values are in the leak check, and secrets are redacted before logging - compliance is detected across every tool an injection could use, plus real system-prompt content in the answer; a structural guard fails the test if a signature also occurs in the payload, so a model that quotes the attack while refusing it is not scored as complying - a scenario whose payload was not provably ingested fails as inconclusive instead of being scored clean - restored the reported-scoring loop dropped in the rewrite; bounded a live run with max_tool_calls/max_runtime Docs: removed two claims that described validations not in the repo, and corrected the SSRF attribution — ssrfGuardedDial returns early for a host that is already an internal address, so its internal-IP refusal covers DNS rebinding; a literal internal IP in http_request is refused by the network_egress class gate, not the dial guard.

A scenario whose payload was never ingested, or where the model was never reached, is failed as *inconclusive* rather than scored clean, and the compliance detector is validated against a deliberately complying mock model.

Compliance signatures are structurally prevented from matching text the payload itself contains, so a model that **quotes the attack while refusing it** — the behaviour the pillar asks for — is not miscounted as compliance. The operator's real `secrets.env` is never written into the fixture (provider keys are passed through the environment; the planted file holds only a canary), the real key values are included in the leak check, and any secret is redacted before it reaches a test log. ```bash +ODEK_PI_E2E=true go test -count=1 -run TestPIE2E ./cmd/odek/ ODEK_PI_BENCH=true go test -count=1 -run TestPIBench ./cmd/odek/ -timeout 40m ``` From 834e150fe24692a8391aedf71f0b78053d383ab3 Mon Sep 17 00:00:00 2001 From: Rolando Santamaria Maso <4096860+jkyberneees@users.noreply.github.com> Date: Tue, 13 Oct 2026 07:07:30 +0200 Subject: [PATCH 3/4] fix(memory,session,telegram,landing): recall stall, dangling-symlink delete, Telegram episodes, honest landing copy Extended-memory recall stall (reported 2026-10-09, never fixed): intent prediction runs on a context detached from the ~5s recall budget so it is not killed the instant that budget is spent, but recall BLOCKED on it, letting a slow memory backend stall a turn for the whole memory-LLM timeout (minutes). Recall now takes the prediction only if it lands inside its own deadline and otherwise returns what the literal query found, while the prediction finishes in the background and still delivers its follow-up suggestions. RED test: 4.0s against a 400ms budget, now 0.44s, with a second test pinning that late predictions still reach the follow-up sink. Session store: a dangling symlink at a session path was listed but undeletable - Exists uses Stat (following links, matching List), so the link read as absent and "odek session delete" refused. HasRemnants now Lstats the path, so a symlink artifact is purgeable. Telegram: a chat reuses one permanent session id and never reaches the session-end path, so its conversations produced no memory episode and were invisible to recall everywhere else. /new archives the conversation - its actual end - and the episode is extracted there, with provenance derived as on every other surface, so a chat that ingested forwards or media yields an untrusted episode that waits for "odek memory promote". Best-effort; never blocks /new. Landing page: every v2.34.6 binary is 14.75-16.25 MB, but the title, meta description, JSON-LD, og:image:alt, body copy, llms.txt and AGENTS.md all claimed "under 15 MB" and the OG card said "~11 MB" - three of four platforms exceeded the claim. Corrected to ~15 MB, and the new OG card drops the number entirely (that is the claim that rotted) in favour of the posture. OG/Twitter descriptions now say what odek is rather than only how to install it.

Blocking the bot (High): MemoryManager.OnSessionEnd* does NOT background episode extraction - it calls llm.SimpleCall on context.Background(), and every other surface wraps it in RunBackground for exactly that reason. Telegram dispatches commands inline on the single update goroutine (only OnTextMessage is offloaded, with a comment explaining the approver deadlock), so /new ran a synchronous LLM call there with a 300s client timeout plus a 15s drain, while holding the per-chat mutex. That stalls every chat and can expire a 120s approval pending in another one. Extraction now runs on its own goroutine, outside the mutex. Overwritten episodes (High): the episode was keyed on "tg-", which ArchiveAndDelete deletes and the chat's next conversation reuses, and the episode index replaces by session id - so a chat could never hold more than one episode and each /new destroyed the previous one. It is now keyed on the archive id via the new ArchiveAndDeleteID; ArchiveAndDelete stays for its existing callers. Stale read (Medium): the session was read before ArchiveAndDeleteID flushes any cached tail, so a conversation whose last writes had not been persisted could yield a truncated episode or none. Extraction now reads the archive, after the flush. Recall follow-ups: a prediction abandoned at the caller's deadline could land after a LATER turn published its suggestions and replace them with a stale set; deliveries are now stamped with a turn generation. The late path also delivers on predictor error, matching the in-budget path which clears the previous turn's suggestions. And the deadline select now probes predCh first, since Go picks randomly when both cases are ready and would otherwise discard a prediction that did arrive in time. Also: README.md and docs/CHEATSHEET.md still claimed "<15 MB" - the exact claim the previous commit set out to retire (real binaries are 14.75-16.25 MB). The test stub now returns a distinct summary per call, so episode dedup cannot mask an overwrite.
