## Summary
Classify the Go test suite by dependency level using build tags so the
default
`go test ./...` run stays self-contained, and add local convenience
commands
plus a documented convention.
- Add build tags to 5 real-service tests that were previously un-tagged
and only
soft-isolated via `t.Skip`: `kg_test.go` (integration), `minio_test.go`
(integration), `template_integration_test.go` (integration),
`stagehand_runtime_integration_test.go` (integration),
`pipeline_e2e_test.go` (e2e).
The default unit run no longer compiles/attempts these.
- Reclassify the full-pipeline `real_consumer` tests from `integration`
to `e2e`.
- Add `build.sh` shortcuts: `--test-integration`, `--test-e2e`,
`--test-manual`,
`--test-all` (integration + e2e; `manual` is excluded and is local
opt-in only,
never run in CI).
- Document the tier scheme (unit / integration / e2e / manual +
orthogonal cgo) in
`AGENTS.md`.
## Tier definitions
| Tier | Build tag | Runs by default? |
|---|---|---|
| Unit | (none) | Yes — in-memory SQLite / miniredis / httptest stubs |
| Integration | `integration` | No (`-tags integration`) — single real
service |
| E2E | `e2e` | No (`-tags e2e`) — full ingest→index→retrieve pipeline |
| Manual | `manual` | No (`-tags manual`) — very slow; never in CI |
## Verification
- `gofmt -l` clean on all changed files; `bash -n build.sh` OK.
- `go list` confirms the default set excludes the tagged files, and
`-tags integration` / `-tags e2e` include them.
- Full regression: unit / integration / e2e each **97 ok, 0 FAIL**.
- Fixed a regression where `pipeline_knowledge_compiler_test.go` relied
on a
transitive import side-effect from `template_integration_test.go` to
register
the `File`/`Parser`/`TokenChunker` components; it now blank-imports the
component packages directly.
## Test plan
- [ ] `./build.sh --test` (unit) passes
- [ ] `./build.sh --test-integration` passes (needs real services; skips
otherwise)
- [ ] `./build.sh --test-e2e` passes (needs real services; skips
otherwise)
