Problem + +`SafetyMonitor` ([safety/monitoring.py](safety/monitoring.py)) records safety +events (e.g. `content_filtered`, `injection_attempt`) so the system can react +when a user trips safety limits repeatedly. In a multi-turn conversation a user +can bypass the per-message content filter by spreading a harmful request across +several turns — each message looks benign on its own, but the pattern across a +short window is not. + +Detecting that pattern requires asking *"how many safety events occurred in the +last N hours?"*. The current code cannot answer that question: + +1. **No per-event timestamps.** `log_event` stores a single cumulative counter + (`INCR safety:events:{type}`) with a key-level 24h expiry. There is no record + of *when* each event happened. +2. **`window_hours` is a no-op.** `get_event_count(event_type, window_hours=1)` + accepts the argument but ignores it (docstring: *"not enforced here"*) and + returns the lifetime total via a single `GET`. + +Result: a 1-hour window and a 1000-hour window return the same number, so a +multi-turn bypass is never reflected in a time-windowed metric. + +## 2. Reproduction + +Test: [tests/unit/test_monitoring.py](tests/unit/test_monitoring.py) :: +`test_window_hours_is_ignored_reproduces_66`. + +It records that 5 events exist all-time but only 2 within the last hour, then +calls `get_event_count("content_filtered", window_hours=1)` and asserts the +result is `2`. Against the current implementation it returns `5` and the test +fails — that failure is the reproduction. + +``` +AssertionError: window_hours ignored: got 5 (all-time total) instead of 2 ... +assert 5 == 2 +``` + +## 3. Proposed fix + +Adopt the same rolling-window pattern already used by +[safety/rate_limiter.py](safety/rate_limiter.py), which stores timestamped +entries in a Redis **sorted set** (`ZADD` / `ZREMRANGEBYSCORE` / `ZCARD`). + +### 3.1 `log_event` — store timestamped events +- Continue validating `event_type` against `VALID_EVENT_TYPES`. +- Instead of (or in addition to) `INCR`, add the event to a sorted set keyed by + event type, scored by the current UNIX timestamp: + `ZADD safety:events:{event_type} {now: now}`. +- Set a key expiry generous enough to cover the largest window we query + (e.g. 24h), so the set self-trims. +- Keep the existing structlog line and the broad `try/except` so logging failures + never break the request path. + +### 3.2 `get_event_count` — enforce the window +- Compute `window_start = now - window_hours * 3600`. +- Trim expired entries: `ZREMRANGEBYSCORE key 0 window_start`. +- Return the count inside the window: `ZCARD key`. +- Preserve the existing behaviour on error (log + return `0`). + +### 3.3 (Optional, if in scope) surface the metric +Grep shows `SafetyMonitor` currently has no callers. If wiring is in scope, call +`log_event(...)` where the content filter / prompt-defense layers flag input, and +expose `get_event_count(..., window_hours=1)` so the agent can react (e.g. warn or +block) when the windowed count crosses a threshold. If out of scope for #66, note +it as follow-up. + +## 4. Testing + +- The reproduction test flips from failing to passing once `get_event_count` + reads the windowed sorted-set count. +- Add coverage for: + - `log_event` calls `zadd` with a timestamp score and sets an expiry. + - `log_event` still rejects unknown event types (already covered). + - `get_event_count` calls `zremrangebyscore` with the correct `window_start` + and returns `zcard`. + - Error path returns `0`. +- Run: `make test-unit` (or `.venv/bin/pytest tests/unit/test_monitoring.py -v`). + +## 5. Risks / considerations + +- **Data-model change:** counts recorded under the old `INCR` key won't carry + over. Acceptable — safety metrics are ephemeral (24h expiry) and dev-only. +- **Memory:** a sorted set is larger than one integer, but bounded by the expiry + window and event volume; the rate limiter already accepts this trade-off. +- **Clock source:** use a single `now` per call, mirroring `rate_limiter.py`. + +## 6. Out of scope + +- Redesigning the content filter's detection patterns. +- Persisting safety events beyond the rolling window (no long-term audit store).

Pending review. + +--- + +### Reflection + +**What was harder than you expected?** +Two things I didn't see coming. First, the repo is seeded with dozens of intentional +bugs, so running `make test-unit` showed 56 failures — it looked like I'd broken +everything, and it took a moment to realize almost all of those belonged to other +issues, not mine. Learning to run just `tests/unit/test_monitoring.py` and judge my work +by *that* was the real skill. Second, Git hygiene tripped me up: a stray full copy of the +project had been cloned inside itself (`pathreview/pathreview/`) which blocked commits, +and at one point my fix and tests got bundled into a single commit mislabeled `test(...)` +instead of a proper `fix(...): Fixes #66`. Cleaning that up mattered more than I expected. + +**What did you learn about working in a large codebase?** +Scope discipline is everything. In my own project I can change anything; here the right +instinct is to touch only my module, match the conventions already in the code, and not +"fix" things outside my issue. The cleanest part of my fix was that I didn't invent a new +approach — I copied the rolling-window sorted-set pattern already used in +`rate_limiter.py`, so `monitoring.py` now reads like the code around it. I also learned to +separate *my* test failures from the pre-existing ones instead of panicking at a red suite. + +**How did AI tools help — and where did they fall short?** +AI was strongest at navigation and drafting: mapping where the bug lived, pointing me at +the `RateLimiter` pattern to mirror, and drafting the Conventional Commit messages, PR +body, and these journal entries. It fell short on anything outside the code — it couldn't +open the PR or run the Slack review (the `gh` CLI wasn't even installed), and the genuinely +judgment-based calls were mine: deciding that wiring `SafetyMonitor` into the content +filter (PLAN §3.3) should be a follow-up rather than scope-creep in this PR. + +**What would you do differently if you started over?** +Commit in small, correctly-labeled steps from the very beginning instead of having to +`reset --soft` and re-split later. I'd also clean up the environment (the nested duplicate +repo) before starting, and decide the scope boundary (§3.3 in or out) up front in PLAN.md +so it didn't stay an open question all the way to the PR. + +**What are you most proud of from this module?** +The reproduction-first workflow. I wrote a failing test that pinned the exact bug — +`window_hours` being ignored so a 1-hour and a 1000-hour window returned the same count — +before touching the implementation, then watched it flip from red to green once the fix +landed. Seeing that single assertion go from `5 == 2` failing to passing made the whole +fix feel provable rather than hopeful. \ No newline at end of file
