Introduces per-role `meta/variants.yml` for declaring multi-variant
deploys (e.g. WordPress Single-Site vs. Multisite) and reshapes the
development deploy CLI to materialise one inventory folder per variant
and iterate them with co-located sync+async passes.
Why:
- The previous single-inventory + Pass-1-then-Pass-2 split deployed each
variant twice and ran the async pass against a host left in a
different variant's state, masking real bugs.
- Inventory and runtime concerns were tangled: variant selection lived
as a runtime extra-var and required cross-stage coordination.
How:
- `roles/<role>/meta/variants.yml` (file format docs at
docs/contributing/artefact/files/role/variants.md): YAML list of
deep-merge overrides on top of `config/main.yml`. Empty entry `{}` is
variant 0 (= legacy payload). 6 roles get their dev overrides moved
here from inventories/dev.yml; WordPress declares 2 variants.
- `utils/runtime_data.py` gains `_build_variants` / `get_variants` and
drops the retired `_active_variants` runtime selector. Loader always
returns variant 0 as the default; non-zero variants reach
`get_merged_applications` as inventory-level `applications.<app>`
overrides baked at init time.
- New `cli/deploy/development/inventory.py`: `DevInventorySpec`,
`plan_dev_inventory_matrix` (pure planner shared between init and
deploy), `build_dev_inventory_matrix` (materialises one folder per
round at `<dir>-<R>`, or `<dir>` when single-variant). Single-folder
paths preserve full backward compat.
- `cli/deploy/development/deploy.py`: matrix loop with per-round
cleanup (only apps whose variant changed AND that are about to
re-deploy), `--variant <idx>` (or `VARIANT=` env) to pin a single
round, and `--full-cycle` (or `FULL_CYCLE=true`) which interleaves
sync + async per round so the async re-deploy targets exactly the
host state the matching sync deploy just produced.
- `cli/deploy/development/exec.py` gains repeatable `--env KEY=VAL` so
bash callers can inject per-run context into in-container helpers
without inlining heredocs.
- `scripts/meta/env/inventory.sh` exports `INVENTORY_VARS_FILE`
(Python mirror in `cli.deploy.development.common.DEV_INVENTORY_VARS_FILE`;
test_inventory_vars_file_spot.py locks them against drift).
- `make deploy-fresh-purged-apps` and `scripts/tests/deploy/ci/dedicated.sh`
switch to a single init + single deploy `--full-cycle`. The
`make deploy-reuse-*` bash scripts honour `VARIANT=` by suffixing
`INVENTORY_DIR`/`INVENTORY_FILE`.
- The 5 `scripts/tests/deploy/local/deploy/*.sh` scripts now delegate
their in-container heredocs to dedicated helpers in
`scripts/tests/deploy/local/utils/`, removing the bash-in-bash
quoting hell.
Tests:
- `tests/unit/utils/test_variants.py` (renamed from
`test_application_variants.py`): loader edge cases, variant-zero
default, retired-`_active_variants` guard.
- `tests/unit/cli/deploy/development/test_inventory.py` (new): planner,
variant baking, builder, `filter_plan_to_variant`, `DevInventorySpec`.
- `tests/unit/cli/deploy/development/test_matrix_deploy.py` (new):
per-round deploy filter, cleanup decisions, `--variant` pinning,
`--full-cycle` per-round interleave.
- `tests/unit/cli/deploy/development/test_inventory_vars_file_spot.py`
(new): drift guard for the bash <-> Python literal pair.
- `tests/unit/cli/deploy/development/test_exec.py` extended for `--env`.
Docs:
- `docs/contributing/artefact/files/role/variants.md` (new): file format.
- `docs/contributing/design/matrix-deploy.md` (new): runtime mechanism
(folder layout, --variant, --full-cycle, cleanup logic).
- `docs/contributing/actions/deploy.md` (new): contributor dev-deploy
flow (make targets, --variant pinning).
- `docs/administration/deploy.md` slimmed to admin-only (was mixed
admin+dev), cross-links to the new contributor doc.
- `docs/agents/action/iteration/role.md` keeps only agent-iteration
recipes; mechanism explanation moved out and linked.
- `docs/contributing/documentation.md` adds the "no self-SPOT
declaration" rule; `applications.md` renamed its SoT header for
consistency.
