The README generator read its author URL out of the ## Credits sections it
writes itself. .mailmap now folds every address a person commits under into
their @infinito.nexus one, whose local part names their social profile, and
that profile becomes the single point of truth for an author.
utils/meta/identity.py parses .mailmap rather than shelling out to
git check-mailmap, which refuses the worktree the test container mounts.
Cross-checked against git over all 14 identities in the history: no
disagreement.
A new env handler carries the committing identity into the container, which
mounts the checkout but not the contributor's git configuration. Without it
both new tests would skip exactly where they are meant to fire:
* tests/integration/meta/test_commit_identity.py fails when the configured
address does not fold, and prints the .mailmap line to add.
* tests/external/repository/test_author_profile.py probes that profile
live, behind a canary so an unreachable instance is not reported as a
missing profile.
Both look at the current address only. Probing every declared author would be
red for people who have not created a profile yet, and a suite that is red for
someone else's omission stops being read.
Marko Pjevac is declared as a role author but has no address here, so his
Credits line stays unlinked.

utils/env 📐
This directory hosts the Python implementation behind make dotenv.
For the general rules that govern READMEs in code directories see documentation.md.
For the per-variable defaults that this code consumes see default.env.
Purpose 🎯
The package converts the committed default.env plus a small runtime context into the gitignored .env at the repo root.
Every module here belongs to one of four roles: parse, resolve, orchestrate, write.
Structure 🗂️
| File | Role |
|---|---|
parser.py |
Read default.env into (values, comments) tuples. |
runtime.py |
Resolve host-context lookups (disk, RAM, hostname, GHA/Act flags, /proc/version, helper-script invocation). |
builder.py |
Thin orchestrator that defines EnvBuilder, BuildContext, and build_env(). Walks the handler registry. |
writer.py |
Serialise an EnvBuilder into a docker-compose-compatible .env on disk. |
handlers/ |
One module per dynamically-computed variable. See handlers README. |
The CLI entry point lives at __main__.py under cli/meta/env/.
Shell consumers source load.sh under scripts/meta/env/.
File Naming 🏷️
- Module names MUST stay lowercase snake_case.
- Pure passthrough or simple parser/writer helpers MUST live directly under
utils/env/. - Per-variable computation MUST live under
handlers/(see handlers README for the naming convention used there). - Test files live in
tests/unit/python/utils/env/and mirror the module name with atest_prefix.
Machine Facts vs Run Facts 🧭
The writer a handler picks decides how long a value lives. Both kinds are registered in default.env and both are visible to the lints; they differ only in whether the generated .env remembers what the environment said.
| Writer | Meaning | On the next make dotenv |
|---|---|---|
eb.setdefault |
machine fact | a non-empty value in the process env is adopted and written back |
eb.set |
run fact | recomputed from BuildContext; whatever the process env said is discarded |
setdefault is the operator-override contract: exporting a key changes it and the change persists. That persistence is why it MUST NOT carry a value an environment declares for a single run. Makefile exports BASH_ENV, so every make recipe sources .env — a value adopted once is re-exported into every later recipe and into every container that mounts the repo, and a per-run decision has silently become a property of the machine.
A key that some environment declares per run therefore MUST be written by a dedicated handler through eb.set. The exporting shell still wins for its own run, because load.sh preserves non-empty caller values when it sources .env; the file keeps the derived default. INFINITO_RUNNING_ON_GITHUB and INFINITO_CACHE_STACK are written this way. Note the consequence: for those keys .env and the running shell can legitimately disagree, and .env is not the authority.
Import Rules 🔗
parser.py,runtime.py, andwriter.pyMUST NOT import frombuilder.pyorhandlers/.builder.pyMUST NOT import individual handler modules; it MUST go through theORDERED_HANDLERSlist exposed byhandlers/__init__.py.- Handler modules MUST NOT import each other (see handlers README).
