-# Step 5 Implementation Record
-
-## Status
-
-Complete as of 2026-07-28.
-
-This record summarizes the completed implementation of
-[Migration Step 5: Promptkit Repository Foundation](step5.md). The
-[main migration roadmap](migration.md) owns the continuing cross-repository
-sequence.
-
-## Completed Work
-
-### Validation And Release Decision
-
-- Added accepted
-  [ADR 0003](../adr/0003-use-maintainer-run-validation-and-tag-only-releases-for-promptkit.md)
-  for maintainer-run Promptkit validation and source-and-tag releases.
-- Preserved accepted
-  [ADR 0002](../adr/0002-split-promptkit-from-scriptorium.md) and its repository
-  split, ownership, independent versioning, and release-order decisions.
-- Reconciled the migration roadmap so Promptkit validation no longer depends on
-  hosted CI or binary packaging.
-
-### Promptkit Module And License
-
-- Created module `gitea.maximumdirect.net/eric/promptkit` at Go `1.25.5`.
-- Added the root `promptkit` package as the only implemented Go package.
-- Kept the module dependency-free and added no placeholder implementation.
-- Preserved GPLv3 wording and attribution while changing the two template
-  example-notice project names to `Promptkit`.
-- Confirmed the existing ignore rules cover Go output, editor and operating
-  system artifacts, `.env`, `go.work`, and `go.work.sum`.
-
-### Policies And Architecture
-
-- Replaced template documentation and architecture material with durable
-  library-specific policies.
-- Assigned canonical documentation ownership, including conditional ownership
-  for public contracts, integrations, internal subsystems, ADRs, roadmaps, and
-  examples that may exist later.
-- Defined the root facade, internal-package direction, consumer boundary,
-  exported-API discipline, error boundary, dependency injection, and repository
-  independence constraints for future extraction.
-- Updated testing policy for deterministic, offline, parallel-safe,
-  behavior-focused, maintainer-run validation.
-- Recorded the root package as the sole implemented component.
-
-### Orientation, Development, And Releases
-
-- Rewrote the Promptkit README without claiming unimplemented APIs.
-- Replaced the contributor guide with task routing, complete local validation,
-  focused checks, and safe sibling-repository workflows.
-- Added the canonical release procedure for annotated semantic Go module tags,
-  validation evidence, publication verification, and consumer release ordering.
-- Added no hosted CI, binary packaging, executable command, or release tag.
-
-### Cross-Repository Acceptance
-
-Promptkit passed, without an active workspace or local replacement:
-
-```sh
-go test ./...
-go vet ./...
-go build ./...
-gofmt -l $(git ls-files '*.go')
-git diff --check
-```
-
-Acceptance also verified exact module and package metadata, all maintained
-Markdown links, clean repository hygiene, the Promptkit origin and tracked
-default branch, the absence of dependencies and prohibited artifacts, and the
-retained GPLv3 license.
-
-Scriptorium acceptance confirmed that ADR 0003 and the migration roadmap
-distinguish Scriptorium's executable CI policy from Promptkit's maintainer-run
-checks, preserve the first-tag release gate, and introduce no production code,
-module dependency, workspace, or replacement change.
-
-## Repository Boundaries
-
-Promptkit foundation changes remain in Promptkit's Git history. Scriptorium
-contains only the durable cross-project ADR and migration-roadmap records. No
-tag was created and neither repository was pushed as part of this work.
-
-## Next Work
-
-Migration Step 6 may now extract and stabilize the application-neutral
-framework. It must not update Scriptorium to consume Promptkit until Promptkit
-passes its documented validation and publishes its first versioned tag.
