  patterns:
    - tools.go with //go:build tools tag to pin dependencies not yet imported by production code
    - Minimal package stubs (package-level doc comments only) as placeholders for future plans
    - Test stubs using t.Skip() with explanation comments referencing implementing plan

key-decisions:
  - "Used tools.go with //go:build tools tag to retain Phase 1 dependencies in go.mod before production code imports them"
  - "CGO_ENABLED=0 enforced via modernc.org/sqlite v1.48.1 (pure Go) — no CGo compiler dependency"
  - "Package stubs created for providers/storage/engine so test files compile and go build ./... succeeds"

patterns-established:
  - "tools.go pattern: pin indirect dependencies used in later plans without importing in production code yet"
  - "t.Skip() stub pattern: test files with descriptive skip messages referencing which plan implements them"
  - "Minimal package stub pattern: package declaration + doc comment only, replaced by implementing plan"

# Phase 01 Plan 01: Go Module Bootstrap Summary

**Go module github.com/salvacybersec/keyhunter initialized with 10 Phase 1 dependencies at pinned versions, compiling binary entry point, and test scaffold with testdata fixtures for scanner integration tests**

## Performance

- **Duration:** 3 min
- **Started:** 2026-04-04T21:01:53Z
- **Completed:** 2026-04-04T21:04:54Z
- **Tasks:** 2
- **Files modified:** 15

## Accomplishments

- Go module initialized with all 10 Phase 1 dependencies pinned (cobra v1.10.2, viper v1.21.0, ants v2.12.0, modernc.org/sqlite v1.48.1, etc.)
- main.go entry point (7 lines) and cmd/root.go stub compile successfully via go build ./...
- Test scaffolding with t.Skip() stubs for pkg/providers, pkg/storage, pkg/engine — go test ./... -short exits 0
- Four testdata fixtures with synthetic key patterns (OpenAI sk-proj-, Anthropic sk-ant-api03-) and negative test case

## Task Commits

Each task was committed atomically:

1. **Task 1: Initialize Go module and install Phase 1 dependencies** - `7994220` (chore)
2. **Task 2: Create main.go entry point and test scaffolding** - `58259cb` (feat)

## Files Created/Modified

- `go.mod` - Module declaration with all Phase 1 dependencies at pinned versions
- `go.sum` - Checksums for all direct and indirect dependencies
- `tools.go` - build-tag-gated imports to retain Phase 1 deps in go.mod before production code exists
- `main.go` - 7-line binary entry point delegating to cmd.Execute()
- `cmd/root.go` - Stub package satisfying main.go import; replaced by Plan 05
- `pkg/providers/providers.go` - Package stub with doc comment; implemented by Plan 02
- `pkg/providers/registry_test.go` - Test stubs for registry loading, schema validation, AC build
- `pkg/storage/storage.go` - Package stub with doc comment; implemented by Plan 03
- `pkg/storage/db_test.go` - Test stubs for DB open, AES-256 roundtrip, Argon2 derivation
- `pkg/engine/engine.go` - Package stub with doc comment; implemented by Plan 04
- `pkg/engine/scanner_test.go` - Test stubs for entropy, keyword pre-filter, scanner pipeline
- `testdata/samples/openai_key.txt` - Synthetic OpenAI sk-proj- key for scanner tests
- `testdata/samples/anthropic_key.txt` - Synthetic Anthropic sk-ant-api03- key for scanner tests
- `testdata/samples/multiple_keys.txt` - Both key types in one file for multi-provider test
- `testdata/samples/no_keys.txt` - Clean file for false-positive verification

## Decisions Made

- Used `tools.go` with `//go:build tools` tag: standard Go pattern to track direct dependencies not yet imported by production code. Without this, `go mod tidy` strips them from go.mod when no source imports exist.
- Created minimal package stub files (providers.go, storage.go, engine.go) with only a package declaration. This allows `_test` packages to compile against them and makes `go build ./...` succeed.
- modernc.org/sqlite v1.48.1 selected (CGO-free, pure Go). This is newer than the v1.35.x referenced in RESEARCH.md but is the current stable release — CGO=0 constraint satisfied.

## Deviations from Plan

None - plan executed exactly as written. One minor deviation to note: the plan referenced `modernc.org/sqlite v1.35.x` but `@latest` resolved to v1.48.1 (current stable). This is a version advancement, not a constraint violation — the CGO-free requirement is still satisfied.

## Issues Encountered

- Initial `go mod tidy` with no source files stripped all installed dependencies from go.mod (expected Go behavior). Resolved by creating source files first (main.go, package stubs) and using tools.go pattern to anchor dependencies.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Module compiles and all tests pass — Plans 02-05 can now add production code and make tests green
- Aho-Corasick dependency confirmed available (petar-dambovaliev/aho-corasick)
- SQLite pure-Go driver confirmed available (modernc.org/sqlite v1.48.1)
- testdata/samples/ fixtures ready for Plan 04 scanner integration tests
