chore: adopt Corestack project standards

Adopt ADRs-only documentation policy, compact base and Go rules, comment lint and TODO checks.

Always validate records with the local docs checker. Skip implementation CI for root Markdown and docs-only changes while retaining coverage for embedded templates and future modules.

 # AGENTS.md
 
-Go module `go.auvem.com/corestack`. Reading map:
+## Commands
+- Check: `go build ./...`, `go vet ./...`, `go test -race ./...`, `go run github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.15.0 run ./...`; from the project root, run the TODO check below.
+- Generate: No code generation is configured; format with `gofmt -w .`.
+- Documentation: `go run ./cmd/docs check`; create records with `go run ./cmd/docs new adr|plan "Title"`. This checker repository uses its local implementation as the source of truth.
+
+## Scope and decisions
+- Before editing under a directory with its own AGENTS.md, read it. Scoped files: none; this root governs the single Go module.
+- Explicit user instructions win; nearer scoped rules override broader rules.
+- Distinguish confirmed requirements, proposed defaults and unresolved decisions; resolve material ambiguity before dependent work.
+- Proposed ADRs are context, not authority; read relevant accepted decisions before changing their scope.
+- Before final review and merge, reconcile affected records against the latest target branch plus the PR, following [/docs/adr/README.md](/docs/adr/README.md).
+- Documentation tier: ADRs only. Create a plan only when work needs durable execution context across areas, phases or sessions; then enable the plans tier.
+- In a sandbox, request required network/cache access before first codegen; on permission/cache errors retry once with that access. Never hand-edit generated output.
+- Shared databases and ports may belong to other worktrees/agents; read project rules before starting, stopping or resetting them.
+- Ask before lint/autofix changes that could alter runtime behavior.
+- Report commands actually run and their results; never claim an unrun check passed.
+- Name branches `<type>/<kebab>` without agent-name prefixes.
+
+## Comments
+- Document package/module purpose, ownership and boundaries, and every public/exported contract in native doc comments; document generated surfaces at their source.
+- Explain why at invariants, auth decisions, concurrency/ordering, destructive edges and deliberate deviations; no narration, changelog comments or commented-out code.
+- Use `invariant: <property>`, `authz: <who and enforcement>`, `shortcut: <limit>, <when to upgrade>` on relevant code; retain Go `Deprecated:` and Rust `// SAFETY:`.
+- Every TODO needs an issue URL; reviewers recheck tagged comments on touched code.
+
+## Project map
+
+Go module `go.auvem.com/corestack`.
 
-- Build and test: `go build ./...`, `go vet ./...`, `go test -race ./...`; format with `gofmt -w .`.
 - Docs format (the spec `docs check` implements): `docs/docs-format.md`.
-- Check records: `go run ./cmd/docs check`. Create one: `go run ./cmd/docs new adr|plan "Title"`.
 - Decisions live in `docs/adr/`, plans in `docs/plans/`. Records are permanent; never rename them.
 - Dependencies are limited to `go.yaml.in/yaml/v3` and `github.com/yuin/goldmark`.
+
+## Go
+- Default backend language is Go; follow existing package boundaries.
+- Define interfaces at the consumer only when a second implementation or a test seam needs one.
+- Wrap contextual errors with `%w`; inspect causes with `errors.Is`/`errors.As`.
+- Do not add package-level mutable state or `init` side effects.
+- Put `context.Context` first in parameters; never store it in a struct.
+- Give every goroutine an owner and a shutdown path.
+- Run `gofmt`, `go vet ./...`, tests and the project's configured linter from the owning module.
+- Use `.golangci.yml` (revive exported/package-comments); the pinned linter command is listed above.

+Baseline copied from corestack/standards at a36288e7cec933a32f4819a1308201027c9f57ec; this project owns and may adapt it.
+
+# Documentation policy
+
+The [corestack/go docs-format specification](https://gitea.auvem.com/corestack/go/src/branch/main/docs/docs-format.md) owns record format, templates, and validation. In scaffolded projects, generate records and run checks with the pinned documentation command in the root AGENTS.md; do not maintain local format templates.
+
+The copied policy is a project-owned baseline that the project may adapt; scaffold re-runs never refresh it unless the owner explicitly asks. The project owns its locked checker pin and upgrades: update the tag and ensure compliance; scaffold re-runs retain the existing pin unless the owner asks.
+
+## Choose the smallest useful tier
+
+| Tier | Use when | Scaffold output |
+| --- | --- | --- |
+| Neither | A single-purpose CLI, library, or script has no consequential architectural choice or durable execution context yet. | No record directories and no docs-check CI step; root instructions tell agents to ask the owner to run scaffold-project to enable records when a consequential choice arises. |
+| ADRs only | Consequential choices need durable rationale, but execution fits a short issue or PR. | Local policy in docs/adr/README.md, ADRs as warranted and docs-check CI. |
+| ADRs + plans | Work spans areas, phases, or sessions and needs durable execution context. | Local policy in docs/adr/README.md, a docs/plans/README.md pointer, ADRs as warranted, one file per plan, and docs-check CI. |
+
+Project size is a signal, not an exemption: a small security-sensitive library can warrant an ADR. Add the CI docs-check step exactly when the selected tier enables records. Change tiers when actual work warrants it; do not create empty record directories in anticipation.
+
+## Decisions and execution
+
+Write an ADR for a consequential choice among real alternatives: difficult to reverse, crossing areas, changing a boundary, data model or security posture, or establishing a convention. Routine details and choices already governed by an accepted ADR or practice guide do not need another record. Read relevant accepted decisions and verify their claims against code before dependent work. Proposed ADRs are context, not authority; only the owner accepts a decision.
+
+Write a plan when work spanning areas, phases or sessions needs durable execution context. Otherwise keep planning in a PR, issue or chat. Each plan has its own file; the directory is the index. Never create a central living plan or living PRD checklist that parallel worktrees continually edit. Closed plans are history, never standing instructions.
+
+Use `write-adr` and `review-adr` when available: they guide reasoning while deferring textual format to repository conventions. Seek independent review and owner acceptance before treating a proposal as binding. Neither a self-check nor an independent recommendation accepts an ADR. ADRs may share a PR with implementation; no separate ADR PR or extra sections are required by this policy.
+
+## Reconcile before final review and merge
+
+Compare the latest target branch plus the PR with the affected decisions and plans, not just the working branch's previous metadata. Update ADR implementation state and `implemented_by` with the real PR URL when delivery evidence supports it. Close finished plans with completion evidence and an Outcome; keep work active when scope remains. Never invent PR links, completed checks, owner acceptance, or delivery evidence. Run `docs check` using the pinned documentation command in the root AGENTS.md after reconciliation.
