# DuckBrain development harness — Makefile
#
# This file (along with tests/, phpunit.xml, composer.*, .gitignore) lives
# ONLY on the develop branch. master is a publish-only vitrine that contains
# nothing but the readable artifact: nobody commits to master directly, and
# no file outside the WHITELIST below ever reaches it.
#
# Daily loop:
#   make test     run the unit suite (sqlite :memory:, no containers, no
#                 network; installs dev dependencies first if missing)
#   ...then develop on develop and commit there as usual.
#
# Multi-engine regression net (run it whenever Model/Database change):
#   make integration            full matrix: brings the test services up,
#                               runs the Integration suite on sqlite, mysql
#                               and pgsql, then takes the services down even
#                               if a leg fails or you interrupt it
#   make integration-engine ENGINE=mysql
#                               single leg (assumes services are already up);
#                               the fastest inner loop while iterating
#   make db-up / make db-down   manage the rootless podman test containers
#                               (mariadb:11, postgres:16-alpine); idempotent
#
#   Hard port constraint: the services must bind default ports 3306/5432 on
#   localhost because Database.php's DSN has no port field; stop any local
#   server on those ports first (db-up aborts naming the port).
#
#   Known red: ModelFilterTest::orderByRandReturnsEveryRow fails on the
#   sqlite and pgsql legs BY DESIGN until the core RAND translation is fixed
#   (finding F1 in openspec/changes/*/add-multi-engine-model-tests/findings.md);
#   the mysql leg passes it and everything else.
#
# Publishing ritual (human only — AI agents must never run it; it commits):
#   1. make publish MSG="feat: ..."   (MSG optional, defaults to "sync: <date>")
#   2. review the new master commit (git log -1 refs/heads/master); if the
#      generated message needs polish, rewrite it BEFORE pushing, e.g.
#      from Emacs
#   3. git push origin master         (manual on purpose: pushing is a
#                                      decision, never a side effect)
#
# How publish builds master — wipe-and-rebuild mirror, no merges, no
# cherry-picks (see design decisions behind establish-dev-publish-workflow):
#   - refuses to run off develop or with a dirty working tree
#   - checks master out into a disposable worktree under .publish/
#     (your current working tree is never touched)
#   - for each WHITELIST path: removes master's copy and checks out develop's,
#     so deleted/renamed artifact files never survive as ghosts in master
#   - BLACKLIST then subtracts noise found INSIDE whitelisted paths
#   - creates the commit only when the artifact actually changed; its body
#     lists the develop commits (after the last-sync tag) that touched
#     WHITELIST paths — pure-noise commits are filtered out automatically
#   - moves the last-sync tag to develop's tip, removes the worktree, and
#     prints any root entry left out of WHITELIST (add it if it belongs to
#     the artifact)
