# Faza 1 closed — quarantined tests
**Quarantine date:** 2026-04-29 (Phase 5 §0 preflight)
**Authority:** PM ratification — Phase 5 deployment §0 preflight 3-ask response, Ask #1 Option 1
**Branch:** `phase-5-deployment-v2`
**Quarantine commit:** see git log this directory
**Vitest exclude:** `**/__faza1-closed/**` added to `vitest.config.ts` exclude list — these files are skipped from collection (no longer load-bearing for current verification).
---
## Quarantined files
| File | Reason |
|---|---|
| `mutation-validator.test.ts` | Pins baseline shape SHAs at Faza 1 substrate freeze `c9bda3d`; `phase-5-deployment-v2` Opcija C inheritance chain doesn't reach `c9bda3d`. PM Ask #1 Option 1 ratified 2026-04-29. |
| `registry-injection.test.ts` | Asserts Amendment 8 H1 failure mode (deep-relative-path REGISTRY ≠ package REGISTRY) reproduces under Node 22.19.0; current Node ESM resolver deduplicates the paths so the assertion fails. CC extended quarantine 2026-04-29 same session — flagged in §0 preflight evidence + commit message; PM advised. |
## Why these tests live here
Tests in this directory pin substrate SHAs against the Faza 1 substrate freeze head `c9bda3d` (Phase 4.7 HEAD on `feature/c3-v3-wrapper`, per `benchmarks/preregistration/manifest-v7-gepa-faza1.yaml` `substrate_freeze_head`). They were load-bearing during Faza 1 GEPA evolution runs (executed inside isolated worktree `D:/Projects/waggle-os-faza1-wt` rooted at `c9bda3d`) to enforce the cell-semantic boundary invariant — the mutation oracle must not modify baseline shape file content during Gen 1+ candidate generation.
`registry-injection.test.ts` documents a SECOND class of Faza 1 closed-work artifact: tests that intentionally assert a buggy state reproduces (so the bug stays detectable if someone "fixes" the canonical path back). Once Amendment 8 fixed H1 via the canonical `registerShape` API + Node ESM resolver dedup behavior changed in subsequent versions, these documentation tests can no longer pass — but their failure carries no Phase 5 substrate signal. The H1 fix is verified independently via `selectShape` + `registerShape` integration tests in the agent suite.
After Faza 1 closure (`6bc2089` — Checkpoint C closure decision `decisions/2026-04-29-gepa-faza1-results.md`), the branch architecture decision **Opcija C** (`decisions/2026-04-30-branch-architecture-opcija-c.md`) determined that:
- `phase-5-deployment-v2` inherits `gepa-faza-1` baseline (= `6bc2089`)
- `gepa-faza-1` parent chain reaches `origin/main` (`5ec069e`), NOT `c9bda3d`
- `c9bda3d` is on the divergent `feature/c3-v3-wrapper` branch (CC-1 Phase 4 work)
- Therefore the SHAs of baseline shape files on `phase-5-deployment-v2` reflect `origin/main` content, not the `c9bda3d` content these tests pin
Running these tests on `phase-5-deployment-v2` produces 14 failures with no Phase 5 substrate signal — the failures are a scope-leakage artifact of post-closure test continuation under Opcija C inheritance, not a bug in either Phase 5 substrate or Faza 1 evolution invariants.
Faza 1 closure verdict §F.4 already documents `105/105 anchor invariance checks PASS` during in-worktree execution + `15/15 held-out anchor checks PASS` during Checkpoint C — the cell-semantic boundary discipline was verified and binding throughout Faza 1.
## What this quarantine does and does NOT mean
- **Does NOT mean** Faza 1 substrate discipline was wrong or the test was buggy.
- **Does NOT mean** baseline shape files have been modified.
- **Does mean** the SHAs the test pins to (`c9bda3d` substrate snapshot) are not reachable from `phase-5-deployment-v2` HEAD without integration sprint work.
- **Does mean** the test is no longer load-bearing for Phase 5 deployment substrate verification (REGISTRY API + registerShape canonical path + gen1-v1 shape definitions are verified independently via Phase 5 §0.1 substrate readiness grep).
## Reactivation conditions
These tests should be re-activated (moved back out of `__faza1-closed/`) when ANY of the following holds:
1. **Post-Phase-5 production-stable integration sprint** (per Opcija C §5) merges `feature/c3-v3-wrapper` into the deployment lineage. Re-pin the test SHAs to the integrated substrate snapshot before re-activating.
2. **Future Faza N evolution sprints** that re-establish substrate freeze inside an isolated worktree. Re-activate the tests inside that worktree's branch context, not on the deployment branch.
3. **Substrate boundary regression suspected** — re-pin SHAs to the current deployment branch HEAD content and re-activate as a drift detector for that specific branch.
Forbidden: simply blanking the SHA pins to silence the test. Replacement pins must be anchored to a documented substrate snapshot with audit-traceable origin.

/**
* GEPA Faza 1 — REGISTRY-injection cross-module-boundary regression test.
*
* Per manifest v7 Amendment 8 §registry_invariant_test.

* Documents the H1 failure mode discovered via Gen 1 partial run b5avslp51 +
* diagnostic probe (benchmarks/gepa/scripts/faza-1/probe-registry-injection.ts):
*
* Under tsx + Node ESM with workspace path resolution, importing REGISTRY
* via a deep relative path produces a SEPARATE module instance from
* importing via the package path '@waggle/agent'. Mutations to one
* instance do NOT propagate to the other.
*
* This test asserts BOTH:
* (a) the failure mode (direct deep-path mutation does NOT propagate
* to package-import REGISTRY), so the bug class stays detectable
* if someone "fixes" the canonical path back to a deep import; AND
* (b) registerShape() via '@waggle/agent' DOES propagate to the
* agent-loop's view of REGISTRY (selectShape sees the new shape).
*
* If this test ever fails on (a) it means the underlying ESM resolver
* dedup-logic changed; if it ever fails on (b) it means registerShape
* was broken or its export path was changed.
