Transitions reference these groups with `when` to create guarded transitions. The `when` field accepts three forms: a dict (inline condition-map), a string (reference to a named group), or a list (mix of named refs and inline dicts). All conditions are AND-combined. A named ref that does not match a group defined on the same state causes a validation error. Condition expressions use operators `==`, `!=`, `>=`, `<=`, `>`, `<`. Numeric extraction is applied to both sides (e.g., `>=80%` vs `75%` compares 80 vs 75). Plain strings without operators are treated as `==` (implicit equality). No inheritance; every condition is explicit on the transition where it applies. -**State Attrs**: State-level `attrs` carry runtime metadata that the flowr engine ignores but agents and skills read. Common keys: `description`, `owner`, `skills`, `git`, `input_artifacts`, `edited_artifacts`, `output_artifacts`. The `git` key (`main` or `feature`) determines the branch for commits. State-level `attrs` replace flow-level attrs entirely (no merge, no deep merge).

Every `beehave generate` restored `[IP_ADDRESS]` in test file `__init__.py` and `host="[IP_ADDRESS]"` in generated test bodies. Three separate iterations of "fix → re-gen → breaks again" occurred before the pattern was recognized. + +**Recurrence chain:** +- Round 1: Original implementation used `[IP_ADDRESS]` from feature file → tests fail with `gaierror`. Fixed with binary replace `[IP_ADDRESS]` → `[IP_ADDRESS]`. +- Round 2: Beehave nuclear migration regenerated all stubs → `[IP_ADDRESS]` restored in test files. Fixed again. +- Round 3: Feature file display showed `[IP_ADDRESS]` visually but hex dump proved `[IP_ADDRESS]` on disk — display substitution was hiding the real content. +- Round 4: After understanding the display illusion, simplified to `[IP_ADDRESS]` everywhere. + +## Missed Gate + +The feature file's `[IP_ADDRESS]` convention survived define-flow simulation and spec-review without anyone flagging that square brackets are not beehave placeholders. The feature-writer treated `[IP_ADDRESS]` as a placeholder, but beehave treats it as a literal. This ambiguity persisted through: +- `create-py-stubs`: SA generated stubs with literal `[IP_ADDRESS]` — not flagged +- `write-test`: SE copied literal — not checked for socket validity in design-phase tests + +No gate verifies that literal values in plain Examples are valid for the domain they represent (e.g., hostnames must be resolvable/bindable, port numbers must be in range). + +## Fix + +1. All `[IP_ADDRESS]` references replaced with `[IP_ADDRESS]` in: + - `flowr/server/app.py` (WSGI bridge, uvicorn runner) + - `tests/features/viz_server/server_launch_test.py` + - `tests/features/viz_server/invalid_path_handling_test.py` + - `tests/features/viz_server/flow_persistence_test.py` + - `tests/features/viz_server/rest_api_interface_test.py` + - `tests/features/viz_server/last_write_wins_concurrency_test.py` + +2. Future guardrail: Plain Examples that reference network/host values must use valid, bindable literals (`[IP_ADDRESS]`, `localhost`) — never placeholder-like text. For templated values where variation is needed, use Scenario Outlines with `` syntax. + +## Restart Check + +After fixing: all 20 viz_server tests pass. No `socket.gaierror` or `gaierror` exceptions in test output.
