Extend the local cache stack with three independent capabilities:
1. Inner-`dockerd` build coverage for HTTP-only package mirrors.
`roles/sys-svc-compose/files/compose.py` (the runner's `compose`
wrapper) auto-generates a transient `compose.cache.override.yml`
per app when `INFINITO_PACKAGE_CACHE_FRONTEND_IP` is exported. The
override pins `build.extra_hosts` for `deb.debian.org`,
`archive.ubuntu.com`, and `security.ubuntu.com` to the frontend.
`pull.py` now delegates to the wrapper so build/pull operations see
the same `-f` set the wrapper auto-detects. nginx in the frontend
gains a port-80 listener with path rewrites for those hostnames,
and `package.sh` registers two new Nexus proxies
(`apt-debian-security`, `apt-ubuntu-security`) for the security
suites whose upstream URL prefix differs from the main archive.
Alpine is intentionally excluded from the inner-build extra_hosts:
3.18+ defaults to HTTPS, and inner-`dockerd` build containers do
not import the frontend CA. Routing apk through the frontend would
trip TLS verification.
2. General cache freshness env-var. `scripts/meta/env/cache/package.sh`
exports `INFINITO_PACKAGE_CACHE_MAX_AGE_MIN` (default `129600`,
i.e. 90 days). The bootstrap helper consumes it for every Nexus
proxy's `contentMaxAge`, `metadataMaxAge`, and
`negativeCache.timeToLive`, replacing the previous 1440-minute
literal. Lower the value when chasing fast-moving upstreams.
3. SPOT cache documentation at `docs/contributing/environment/cache.md`.
`compose.yml.md`, `variables.md`, the per-service READMEs, and
`requirements/012-...` now link to it instead of restating the
stack's behaviour. Net documentation lines drop substantially while
the cache page becomes the single user-facing reference.
Also: code-comment cleanup per `docs/contributing/documentation.md`
guidelines across all touched .py / .sh / .yml files. Multi-paragraph
docstrings, banner separators, and restate-the-obvious comments are
removed; one-line WHY comments remain where the rationale is not
already visible in the code.

Brings up the package-cache compose service alongside the existing
registry-cache, gated by the same `cache` profile. Bootstrap helper
(scripts/docker/cache/package.sh) auto-rotates the admin password from
the well-known default, accepts the Sonatype CE EULA (3.71+ blocks
artifact downloads with HTTP 403 until /v1/system/eula is POSTed —
disclaimer must be sent verbatim with its unicode quotes), enables
anonymous read, creates one default blobstore, and registers the MVP
proxy set: apt-debian, apt-ubuntu, pypi-proxy, npm-proxy, helm-bitnami,
raw-githubusercontent. The runner gets pip.conf / .npmrc /
sources.list snippets bind-mounted in (each defaulting to /dev/null
when the cache profile is inactive) so the deploy is byte-identical
with cache off.
Cache plumbing:
- scripts/meta/env/cache/{registry,package}.sh: per-cache env defaults,
hostname-derived admin password seed (uses `hostname` command, not
$HOSTNAME shell var, so the value is identical across interactive
shells, non-interactive subshells, and Python subprocesses).
- scripts/docker/cache/{registry-ca,package}.sh: container-side
bootstrap helpers, both moved under scripts/docker/cache/.
- scripts/system/cache/clean.sh + `make cache-clean`: wipes both
/var/cache/infinito/core/cache/{registry,package} dirs and stops
the cache containers.
- cli/deploy/development/compose.py: Profile gate exports the three
new INFINITO_PACKAGE_CACHE_* client-snippet paths and runs the
bootstrap helper after the package-cache reports healthy.
Compose service uses sonatype/nexus3:3.91.1-ubi pinned, runs as
root (UBI image refuses to chown a fresh bind-mount), and forces
NEXUS_SECURITY_RANDOMPASSWORD=false so the bootstrap can log in with
admin/admin123 before rotating; the random-password mode otherwise
auto-completes onboarding silently and leaves no readable secret on
disk for an automated bootstrap to pick up.
Tests: tests/unit/cli/deploy/development/test_compose.py grows two
new assertions (cache services listed in `up` args when local; build
tests pin CI=true to retain ci-only assertions).
Closes req-012.

Move the registry-cache pull-through proxy out of the always-on `ci`
profile into its own `cache` profile, and select it based on the runtime
environment instead of statically.
Why
The proxy only earns its keep when image pulls amortize across many
runs on the same host. That holds on developer machines (cross-run
image dedup, persistent host disk) but not on GitHub-hosted runners
(fresh disk per job), where the proxy startup overhead is net loss
without the corresponding payoff.
How
* Compose: split `registry-cache` into its own `cache` profile;
`infinito.depends_on.registry-cache` gets `required: false` so Compose
does not auto-start the proxy via the dependency when the profile is
inactive; the systemd drop-in bind-mount source is gated by the new
`INFINITO_REGISTRY_CACHE_PROXY_CONF` env var with `/dev/null` default,
so dockerd loads an empty drop-in (no `HTTP_PROXY`, no `ExecStartPre`)
when the proxy is not running and pulls images directly.
* New `cli/deploy/development/profile.py` `Profile` class is the SPOT
for which compose profiles activate. KISS + SRP: `is_ci()` reads the
three CI signals (`GITHUB_ACTIONS`, `RUNNING_ON_GITHUB`, `CI`),
`registry_cache_active()` is its strict inverse, and `args()` returns
the matching `--profile ...` flag list.
* `Compose` and `down.py` consume the same `Profile` so up/down cannot
drift on which services are part of the stack.
* Documentation under `compose/registry-cache/README.md`,
`docs/contributing/artefact/files/compose.yml.md` and
`docs/contributing/environment/variables.md` describes the new toggle
and the `INFINITO_REGISTRY_CACHE_PROXY_CONF` env var. Pre-existing
documentation.md violations in those files (one SPOT self-label, one
em dash, two path-as-link-text instances) corrected in the same pass
per the fix-nearby rule.
* Tests: 14 new `Profile` unit tests in `test_profile.py` plus two
scenario tests in `test_compose.py` that lock down the
`--profile ci` (CI runner) vs `--profile ci --profile cache` (local)
argument shape.

Introduces a `registry-cache` service (rpardini/docker-registry-proxy) in
the `ci` profile that MITM-caches every outbound docker registry pull
made by `infinito`'s inner dockerd, drastically cutting bandwidth on
re-deploys, parallel CI shards, and local fresh-purges.
Wiring (all bind-mounted via compose.yml, no Dockerfile or entry.sh
staging, so edits hot-reload on next container start):
- CA bundle at /opt/registry-cache-ca (read-only),
- systemd drop-in at /etc/systemd/system/docker.service.d/registry-cache-proxy.conf,
- registry-cache-ca.sh at /usr/local/bin/registry-cache-ca.sh.
The drop-in registers registry-cache-ca.sh as ExecStartPre. Compose
gates `infinito` on `registry-cache` `service_healthy` so the CA is on
disk before dockerd boots; the install script supports both Debian
(`update-ca-certificates`) and Arch/Fedora (`update-ca-trust extract`)
trust stores, detected by command availability.
Also reorganizes compose/ into per-service subdirectories
(compose/coredns/, compose/registry-cache/) with README.md per directory
following the documentation guidelines, adds scripts/docker/README.md,
and nests the registry-cache host paths under /tmp/infinito/core/
(mirror/ for blobs, ca/ for the MITM CA bundle).
