.env was seeded only when absent, so a re-run with a corrected value logged
".env exists; leaving it alone" and dropped it. That looked harmless because
compose reads the shell environment before .env: an exported BIND_ADDR did
narrow the bind for that run, `ss -ltn` confirmed it, and the deploy reported
success -- while .env still said 0.0.0.0.
The drift surfaces later. The documented update path is a plain
`docker compose up -d`, which has no such environment, falls back to .env, and
republishes an SSL-bumping intercepting proxy on every interface. Nothing
warned. TRUSTED_CIDR has the same shape: a tightened allow-list silently
reverts to whatever .env kept.
Record which runtime keys actually arrived in the environment BEFORE the ":="
defaults run -- PROXY_PORT especially, whose default is a non-empty 3128, so
afterwards an unset variable is indistinguishable from a supplied one. On a
re-run, write just those keys through with the existing set_env() (a targeted
per-key rewrite, not a file overwrite) and log each change. Keys not passed
that run are untouched, so hand-edits to .env survive.
Verified: narrowing BIND_ADDR updates .env and logs it; a re-run with nothing
exported leaves .env alone; re-passing identical values is a silent no-op; and
a hand-edited PROXY_PORT=8080 survives all three, which is what the
capture-before-defaults ordering exists for.
Found by an adversarial sweep for the openbao bug class (920edc5), then
confirmed by hand.

New deployments/squid/: an explicit forward proxy with SSL-bump TLS
interception (local CA, generated on first deploy) and hostname-targeted
static-content caching. Unlike the other stacks it is a forward proxy, not
a Caddy/Let's-Encrypt inbound site.
- Self-built minimal Alpine image (apk squid ships ssl-bump); entrypoint
renders squid.conf and generates the cache policy from the domain lists.
- Wildcard hostname caching (cache-domains.txt leading-dot + optional
cache-domains.regex); boost vs strict-allowlist toggle (CACHE_ONLY_LISTED).
- Storage gate never caches HTML or dynamic content; query strings exempt on
boosted domains so versioned static assets still cache.
- splice-domains.txt passthrough for pinned/banking domains.
- Deny-by-default http_access (TRUSTED_CIDR) + BIND_ADDR pinning; CA key 0600
on host, never embedded, git-ignored.
- Wired into automations.sh, README, .gitignore; cloud-init for fresh VMs.
