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.

Environment Layer 🌍
This directory contains the shared environment bootstrap layer for Infinito.Nexus scripts. ✨
Its purpose is to keep runtime configuration centralized, deterministic, and easy to reuse across local runs, CI, and container-based execution. 🧭
The design follows simple composition principles so environment state can be loaded safely and consistently without duplicating logic in many places. 🧱
Use the directory-level entrypoint for sourcing this environment context in scripts and automation. ✅
Modules 📦
The directory has two kinds of env modules:
-
Always-on modules are composed by
all.shand SHOULD be sourced by anything that needs the standard project environment (Python interpreter, distro defaults, runtime context, inventory paths, GitHub markers):python.sh,runtime.sh,defaults.sh,inventory.sh,github.sh. -
On-demand modules MUST NOT be composed into
all.shbecause they encode an intent that only makes sense in a specific call path. The deploy-only marker is the canonical example:ci.shexportsINFINITO_MAKE_DEPLOY=1soMODE_CI(defined ingroup_vars/all/01_modes.yml) flips totruefor the duration of a make-driven deploy. It is sourced by every deploy entry-point underscripts/tests/deploy/local/deploy/. Sourcing it fromall.shwould set the marker for unrelatedmake test*ormake build*recipes too, which is exactly what requirement 006 forbids.
