name	code-seal
description	Finalizes application code units—modules, pure functions, API handlers, boundary refactors—by verifying the win gate, freezing the diff, and marking handoff-ready. Triggers on /code-seal and briefs like “add a pure function + tests without touching HTTP” or “stabilize one export while swapping internals.” Differentiator: call-site audited minimal unit with typed evidence, not a sprawling finalize pass.

Core Mandate / Invariants

• Domain: application code, modules, refactors, APIs—not infra, docs-only, or mesh orchestration.
• Method finalize: prove the win gate, freeze outputs, mark handoff-ready.
• Evidence over assertion: every claim backed by command output or repo proof.
• Smallest reversible unit; match existing module style and public contracts.
• No invented types/symbols; no drive-by refactors outside the brief.
• Escalate multi-package or ambiguous ownership to review or /opgrok.

Procedural Workflow

Domain procedure

1. Resolve owning module and public surface: rg -n "export (function|class|const|type|interface)" <pkg> (or language equivalent); map importers with rg -n <symbol> --type-add 'src:*.{ts,py,rs,go}' -t src.
2. Implement the minimal unit that satisfies the brief; keep public signatures stable unless the brief renames them.
3. Scope verification to touched packages only—fix once, then escalate to debug/test.

Role method (seal)

1. Restate acceptance: tests green, public API stable, docs only if contract changed.
2. Run package-local typecheck + tests and paste evidence, e.g. tsc -p packages/foo --noEmit, mypy -p foo --no-error-summary, cargo check -p <crate> --lib, pytest -q path/to/test_*.py, go test ./pkg/foo -count=1.
3. Call-site audit before any rename/move: rg -n <old_symbol>; fix or gate every hit in-diff.
4. Freeze file list + emit WIN PASS|FAIL with paths and commands.

Eval dimensions

• Correctness of the unit under test
• API stability / blast radius
• Diff thrift (lines changed vs value)
• Test evidence quality

Close

1. Verify: win-gate evidence attached; build/typecheck/tests for touched packages. On failure, fix once or escalate to review.
2. Emit:

WIN: PASS|FAIL
SG: sg-0006 code-seal
EVIDENCE:
- ...

Constraints & Gotchas

• Public signature drift breaks silent consumers—audit call sites before rename/export change.
• Partial refactors leave dead imports and dual paths; delete or feature-gate the old path in the same diff.
• Any / untyped boundaries hide errors until production paths; tighten types at the sealed edge.
• Half-wired feature flags: both branches must typecheck and have at least one test.
• Barrel re-exports (index.ts, __init__.py) silently widen blast radius—check them on every move.
• Generated/lockfile noise in the same commit obscures the unit; keep seal diffs reviewable.
• Do not use outside software construction (route via /cat-code or /opgrok).

Anti-patterns

• Drive-by renames across unrelated packages
• New framework to fix a one-file bug
• Committing vendor/generated noise with the feature
• Repo-wide “cleanup” under a single-handler brief
• Dual-writing old and new APIs without a removal plan
• Exploits, malware, or undisclosed destructive automation

Definition of Done

• Deliverable matches the brief under seal for software construction.
• Touched packages typecheck/test green; call sites reconciled if surface moved.
• WIN: PASS with concrete commands and paths; WIN: FAIL states blocker and next owner.
• Downstream SuperGroks can consume outputs without clarification.

Optional Tool Surface

• rg / grep — symbol + call-site discovery (rg -n, --type-add)
• tsc -p <pkg> --noEmit, mypy -p <pkg>, cargo check -p <crate>, go test ./... -count=1
• pytest -q <path>, cargo test -p <crate> --lib, package-local runners only
• read_file, search_replace, run_terminal_command for minimal diffs
• Binary id: opgrok.sg.code-seal
