kevinveenbirkenbachandClaude Opus 5 cb1ff29951 fix(ci): decide discovery's row selection on the set that actually deploys
clone and covered_by both name a stand-in row: another row carries this one's coverage, so the sweep may drop it. Both were decided over every row and then applied to a filtered set, so a run that selected a subset deferred to a stand-in the filter had already removed - the row was cut in favour of a deploy that never happens. --whitelist svc-db-mariadb yielded no row at all, and the swarm-zombie job passed green while drilling nothing.

The sort's last-resort tie-breaker was drawn per process, so discovery and the plan renderer could name different assignments for the same run. INFINITO_DISCOVERY_SEED derives it from the row's own identity instead; the workflow feeds github.run_id, so the rotation still happens, once per run rather than once per process.

Measured against the previous order: on the mode-only filter both cut sets are identical (swarm 220 rows, 44 cut; compose 243 rows, 54 cut), so the full sweep is unaffected.

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/utils/env/ and mirror the module name with a test_ prefix.

Import Rules 🔗

  • parser.py, runtime.py, and writer.py MUST NOT import from builder.py or handlers/.
  • builder.py MUST NOT import individual handler modules; it MUST go through the ORDERED_HANDLERS list exposed by handlers/__init__.py.
  • Handler modules MUST NOT import each other (see handlers README).
