The production compose still carried `build:` keys and no `image:` keys, so a
`git clone` onto the CX22 followed by `docker compose up -d` would have started a
fat-LTO release build of 427 crates on a 2-vCPU/4 GB box — the outcome the whole
build-on-the-Mac decision exists to avoid, reached silently because `pull` skips a
service it is told to build rather than failing.
Both services now pull `registry.mc02.dev/eventsnap/*:${EVENTSNAP_VERSION}` with the
`:?` form, so a missing tag fails the command instead of resolving to an empty one.
`docker-compose.build.yml` restores the `build:` keys for the workstation that
produces the images, from the same context paths.
Also here:
- `DOMAIN` gets the same `:?` guard. Blank did not fail — it produced `https://` for
the frontend's ORIGIN and collapsed the Caddyfile's site block into a malformed
global block, so the stack came up with no TLS and no site.
- `stop_grace_period: 20s` on the app. Docker's default stop timeout is 10s, exactly
the app's own drain budget, so a redeploy could SIGKILL the process at the moment it
was finishing — truncating the in-flight upload the graceful shutdown protects.
- `COMMENTS_ENABLED` is pinned "false" alongside MEDIA_PATH. It is a product decision
for this event, and `.env.example` ships the generic `true`; pinning it means an
operator who copies the example and edits only the secrets cannot ship comments on.
- The frontend runtime stage now copies the lockfile and uses `npm ci`. Without it the
three `^`-ranged deps re-resolved at build time, so an image rebuilt days later could
differ from the one that was tested. Image also drops 120 MB -> 65 MB.
- `docker-compose.dev.yml` told the operator that production had the same `$`-eating
bug and to escape the hash as `$$` in `.env`. That is wrong and it breaks a working
deployment: Compose uses single-quoted env_file values literally, and doubling
produces a 74-character string `looks_bcrypt` rejects. Verified with `printenv`.
The runbook's rollback pointed at `v0.12.0`, which has 6 migrations against HEAD's 22
and was never built or pushed — running the emergency card's rollback line would have
crash-looped the app with `VersionMissing` during the event. §9 now has you tag one
build twice so the rollback target is bit-identical, and says plainly what that can and
cannot fix. Every `$DOMAIN` command gained the `set -a; . ./.env` it needs, the
down-migration psql commands are wrapped in `sh -c` so the container expands the
credentials rather than sending `-U ""`, and the advice to lower `max_video_size_mb`
is withdrawn: the client guard it was premised on does exist, but is pinned to a
compile-time constant, so lowering the DB value only moves failures later.

Running in a container picked up host-oriented values from .env via env_file:
- MEDIA_PATH pointed at a host path that doesn't exist in the container, so every
upload 500'd with EACCES; point it at the /media volume mount.
- ADMIN_PASSWORD_HASH lost its $-delimited bcrypt segments to Compose interpolation
(admin login 401'd); re-supply it with $$ escaping.
- COMMENTS_ENABLED=false to smoke-test the comment kill-switch.
NOTE: production compose + .env carry the same MEDIA_PATH / admin-hash pitfalls.

Address the seven findings from the security & deployment review.
High:
- upload: make infer authoritative — reject files it can't identify
(SVG/HTML/JS) and require the detected MIME to be on an ALLOWED_MEDIA
allowlist; derive the stored MIME and on-disk extension from the
detected type, ignoring client filename/Content-Type. Closes the
stored-XSS vector via media served on-origin.
- deploy: rename docker-compose.override.yml -> docker-compose.dev.yml
so the default `docker compose up -d` no longer publishes Postgres
5432 to the host; the port map is now opt-in via -f. README updated.
Medium:
- upload: DefaultBodyLimit::disable() -> max(576 MiB) as an HTTP-level
OOM backstop; handler still enforces precise per-class size limits.
- docker: run backend and frontend as non-root users.
Low:
- social/upload: event-scope toggle_like, list_comments, add_comment,
delete_comment, edit_upload, delete_upload via find_by_id_and_event /
soft_delete_in_event — cross-event IDs now resolve to 404.
- Caddy: site-wide HSTS / nosniff / X-Frame-Options / Referrer-Policy,
plus Content-Disposition: attachment on /media/originals/*.
- .env.example: replace default Postgres password with a CHANGE_ME hint.
Out of scope: localStorage JWT (root cause fixed; httpOnly cookies are a
larger change tracked separately).
Verified: cargo build (no new warnings), cargo test (3 passed),
caddy validate, docker compose config (no 5432 published by default).
