# ReleaseKit staged implementation plan

Status: Proposed. All stages are pending; this document introduces no implemented
features or published contracts.

Date: 2026-10-05

## Purpose and baseline

This plan gives a Luna coding agent bounded implementation assignments, in
execution order, for the target state in the [feature roadmap](releasekit.md).
The roadmap owns product intent and selected release conventions. This document
owns implementation steps, dependencies, acceptance evidence, and progress.

The baseline is ReleaseKit commit `43c20b0`. It contains documentation, adopted
policies, licensing notices, and [ADR 0001](../adr/0001-public-facade.md). It has
no Go module, packages, executable, tests, or publication automation. The
worktree was clean when this plan was prepared. The available tools were Go
1.26.8 on linux/amd64 and Git 2.53.0; these observations are not minimum support
requirements.

The six sibling checkouts are consumer evidence and future migration targets.
They are independent repositories. Their source and instructions must be
rechecked before each migration; the earlier line counts are historical review
measurements. Consult their code through the knowledge graph, indexing a
repository when necessary. Documents, scripts, and CI configuration may be read
directly under the discovery instructions.

## Execution instructions

- Implement stages in integer order. Each stage is one assignment; finish its
  acceptance checks and local commit before starting the next stage. Record
  completed work and evidence here. Read the stage's dependencies and relevant
  decisions before editing.
- Start with the [developer guide](../development.md) and applicable policies.
  Architecture, testing, documentation, and release policies apply to the core
  implementation. Read the OSS policy when incorporating third-party material.
- Follow the [architecture policy](../policy/architecture.md) and ADR 0001.
  Add exported declarations as their behavior is implemented, with GoDoc.
  Implement the selected contract with proportionate internal collaborators.
- The design choices below specify this draft's recommended implementation.
  They become implementation instructions when the plan is approved. Later
  agent-authored code or tests provide evidence of implementation, rather than
  independent authority to strengthen the contract.
- For each stage, run focused behavioral checks for its changed risks and the
  established offline default suite. Reuse unchanged evidence where appropriate.
  Stage acceptance checks are development checks; they add no publication gates
  beyond the release policy and a repository's selected candidate checks.
- Use temporary repositories, local bare remotes, test programs, and local HTTP
  servers. Keep fixtures independent of the six consumer checkouts and real
  services. Temporary fixture module replacements may connect test programs to
  this checkout; keep them outside committed production module configuration.
- Update canonical documentation with each implemented responsibility. Create
  consumer, CLI, configuration, integration, and internal documents when they
  have substantive content. Keep future behavior and stage progress here.
- Consumer migration stages change the named sibling repository as well as any
  corresponding ReleaseKit examples. Follow that repository's policies, preserve
  unrelated work, and commit each repository separately. When adding a runtime
  dependency, update its module metadata and OSS attribution/companion license
  texts in the same change using the actual selected source pin. A migration
  needs a reachable immutable ReleaseKit pin, as described under Open Questions.
- Local implementation commits and tests against temporary remotes complete
  stages. Real release publication, remote pushes, CI activation, and credential
  provisioning require the maintainer's corresponding authorization. Do not
  equate prepared integration with verified live delivery.

## Implementation decisions

### Module, runtime access, and public ownership

Use one module, `gitea.maximumdirect.net/eric/ReleaseKit`, preserving the case
advertised by the forge's Go import metadata. Set the initial Go language
baseline to `go 1.25.0`, matching the oldest consumer module line. Use APIs
available on that baseline. Actual execution uses a prepared local toolchain
capable of building the consumer; Narratio already needs Go 1.26. There is no
mandatory multi-toolchain release matrix.

The supported packages are the root `releasekit` facade and `buildinfo`. Put
the executable at `cmd/releasekit`. Start with standard-library implementations
and the installed Git and Go executables. Introduce internal packages as their
responsibilities land: runtime information, process execution, release engine,
Git operations, builds, Gitea transport, and CLI adaptation. Put command-owned
parsing and file-format helpers under `cmd/releasekit/internal/cli`; keep facade
calls in the `cmd/releasekit` controller. Those helpers return their own settings
for explicit conversion by the controller and import neither public facade.
The executable therefore consumes the supported APIs while library internal
packages retain inward dependencies. There are no public transport clients or
assembly APIs.

The initial runtime API is `buildinfo.Version() string`. It returns an injected
release identifier when supplied; otherwise it uses the running executable's
main-module version when present and different from `(devel)`, then `dev` when
that metadata is unavailable. This supports source installs as well as explicit
release builds. It describes the application version, not the ReleaseKit
dependency version. [Go build information](https://pkg.go.dev/runtime/debug#ReadBuildInfo)
documents the main-module metadata available to implement this fallback.

Keep the injected string private in the internal runtime implementation. Keep
the linker symbol identifier in a small internal contract used by the builder.
The builder and runtime implementation change together. Consumers call the
accessor; their configuration supplies no linker symbol. The runtime import
graph uses the standard library and small runtime implementation, independent
of orchestration. A tool/runtime version mismatch must be exposed by the native
version smoke check; do not introduce an exact dependency-version equality gate.

### Orchestration API

Implement these root operations as the corresponding stages land:

| Operation | Request and result responsibilities |
| --- | --- |
| `Check(ctx, ReleaseRequest)` | Capture and validate a local committed candidate; return its commit and version. This diagnostic operation does not query publication services, create a tag, or claim remote readiness. |
| `Publish(ctx, ReleaseRequest)` | Validate once, check authoritative state, create and publish the selected annotated tag, and return publication state and retained recovery facts. |
| `Build(ctx, BuildRequest)` | Build the selected targets with the requested version, verify a native version invocation, and return source identity and generated artifacts. |
| `Deliver(ctx, DeliveryRequest)` | Verify tagged source and supplied artifact identity, create or find a hosted release, compare content, and add missing assets with explicit partial or uncertain outcomes. |

Each operation returns a facade-owned result and an error. Requests carry the
repository directory explicitly. `ReleaseRequest` also carries the display
product name, version, selected remote, optional validation callback, optional
build specification, and optional output writer. The remote defaults to
`origin`; publication uses `main`. The callback receives a facade-owned
`Candidate` containing directory, captured commit, and selected version. A nil
callback selects the default Go test invocation. A supplied callback replaces
that invocation with the repository's complete selected validation; it is
called once. The CLI adapts configured commands into this callback.

A build specification carries main package, binary name, and targets. Each
facade-owned `Target` contains Go OS and architecture strings. A build request
adds version and output directory. A delivery request identifies version,
product, repository directory, Gitea destination, and optional build result.
The Gitea destination carries base URL, owner, repository name, and caller-supplied
token. Library code obtains no credentials from ambient configuration. Before
the first remote write, an inspection failure reports that this invocation has
not attempted mutation. Reserve uncertain-mutation classification and exit 3
for writes whose authoritative outcome remains unresolved.

Publication results identify version, candidate commit, captured endpoint,
phase, and tag object when created. Use distinct states for `not_attempted`,
`not_published`, `published`, `conflict`, and `unknown`. These describe this
invocation; a pre-existing remote release is not described as unpublished.
Delivery results identify release URL and the matching, uploaded, pending, and
uncertain assets, with `not_attempted`, `complete`, `partial`, `conflict`, or
`unknown` state. Ordinary errors preserve useful causes through wrapping.
Document exactly when nonzero results accompany errors. Add only the named
types needed to represent these responsibilities; field spelling and internal
package layout can follow idiomatic Go without changing the decisions here.

### CLI and configuration

Use standard-library flag parsing and JSON configuration. The default profile
is `<repository>/releasekit.json`; `--config` selects another file. Configuration
paths are resolved from the selected repository, whose default is the current
directory. A profile supplies product identity, remote, candidate commands,
optional build specification, and optional Gitea delivery declaration. The
command supplies the version rather than persisting it in the profile.

Use this eventual profile shape; add each optional responsibility only when its
stage implements it:

```json
{
  "product": "Scriptorium",
  "remote": "origin",
  "checks": [{"args": ["sh", "scripts/check-release-candidate.sh"]}],
  "build": {
    "main_package": "./cmd/scriptorium",
    "binary_name": "scriptorium",
    "targets": ["linux/amd64", "linux/arm64"]
  },
  "delivery": {
    "base_url": "https://gitea.maximumdirect.net",
    "owner": "eric",
    "repository": "scriptorium",
    "token_env": "GITEA_RELEASE_TOKEN"
  }
}
```

This is a planned example, not an existing file or working invocation. Command
entries also accept an `env` map. Run argument vectors directly, without
implicit shell parsing. A repository that needs shell syntax selects `sh` or
`bash` explicitly. Run commands in the captured repository directory and supply
`RELEASEKIT_VERSION` and `RELEASEKIT_CANDIDATE` for candidate-specific checks.
Those captured values take precedence over conflicting command environment
entries. Inherit the remaining environment and overlay explicitly owned values
without mutating the caller process.

An absent or empty check list selects `go test -count=1 ./...`; a nonempty list
is the repository's complete validation sequence. Decode profile fields
strictly so unsupported build or delivery settings cannot silently disappear
from the selected checks. Validate required values for the operation being run;
a source-only profile needs neither a main package nor credentials.
The CLI loads the token named by `delivery.token_env`, defaulting to
`RELEASEKIT_GITEA_TOKEN`, only for delivery. Build receipt identity covers resolved
build inputs; delivery credentials, destination, and unrelated check settings
are excluded from that identity.

The eventual command forms are:

```text
releasekit version
releasekit check [--repo DIR] [--config FILE] VERSION
releasekit publish [--repo DIR] [--config FILE] VERSION
releasekit build [--repo DIR] [--config FILE] [--output DIR] VERSION
releasekit deliver [--repo DIR] [--config FILE] [--assets DIR] VERSION
```

Flags precede the positional version. `version` prints `releasekit <version>`.
Use exit 0 for completed success, 1 for a known failure or conflict, 2 for usage
or invalid configuration, and 3 for an uncertain remote mutation. Library
outcomes retain more detail. Send validation progress and diagnostics to stderr;
stdout presents the command's final result. Signals cancel the operation through
its context. There is no interactive confirmation loop.

### Candidate checks and Git publication

Parse stable versions using the roadmap's exact syntax. Validate decimal
components as strings without introducing a machine-integer size limit. Read
the release note from the captured commit at `docs/releases/<version>.md`. Its
first line must be a Markdown H1 containing the configured product name and
exact version as complete title elements. Preserve the note content for the annotated tag.
The shared tool imposes no additional note section inventory.

`Check` checks a clean worktree and index on `main`, captures HEAD, checks the
committed note and unused local version, runs validation and selected builds,
and rechecks local mutable state. `Publish` adds authoritative endpoint and
remote branch/tag checks before validation and immediately before publication.
Cleanliness includes untracked files; ordinary Git ignore rules still apply.
Snapshot resolved request values and CLI profile content for the invocation so
configuration is not reloaded into different checks midway through the run.
Source changes remain subject to the ordinary candidate rechecks. The Go API
accepts caller-supplied values without requiring a particular profile file.

Resolve the selected remote's effective push destination using Git's own remote
configuration semantics. A missing destination or more than one distinct
effective publication destination is an actionable configuration error because
this operation needs one authoritative endpoint. A separate fetch URL is
supported. Inspect the publication endpoint,
rather than assuming the selected remote's normal fetch URL is authoritative.

Use a transient, command-scoped named remote with explicit read and push URLs
and mirror mode disabled. Verify that both effective URLs equal the captured
publication destination after Git URL rewriting. Reuse that scoped remote for
queries and push; persist no new remote configuration. Retain normal Git
credential and transport settings, carrying remote-specific transport settings
into the scoped remote as needed. If rewriting prevents establishing this
equality, report the unresolved destination before mutation.
Recheck the original remote resolution before pushing. Test ordinary
`insteadOf`, `pushInsteadOf`, and explicit push-URL cases using local remotes.
[Git's remote documentation](https://git-scm.com/docs/git-remote) describes the
effective URL lookup on which this relies.

Use exact ref names in remote queries. Require authoritative `main` to equal
the captured candidate and the selected tag to be absent. Create the annotated
tag from the committed note with signing disabled for this invocation, inspect
its object type and peeled commit, then freeze its object ID. Push
`<tag-object-id>:refs/tags/<version>` with automatic following of tags and mirror
defaults disabled. Publish no branch updates, unrelated tags, or force updates.

A successful push returns immediately as published. After a failed or ambiguous
push, make one authoritative tag query: an exact object match confirms success;
absence confirms not published at observation; a different object is conflict;
an unavailable or uninterpretable answer is unknown. Retain the local tag in
all failed or uncertain cases. Caller cancellation after push starts also needs
this bounded reconciliation attempt using a separate finite recovery context.
Use a 30-second recovery deadline as an operational default, not a guarantee
that the endpoint will respond. Cancellation before push does not initiate it.

The last remote branch check is an observation before the tag push. This design
provides no transaction locking remote `main` against concurrent writers. Do not
add branch pushes or assert stronger concurrency guarantees in tests.

### Go execution, builds, and assets

For ReleaseKit-owned candidate Go commands and builds, use prepared dependencies
and a local toolchain. Set child environment values `GOWORK=off`, `GOPROXY=off`,
`GONOPROXY=none`, `GOSUMDB=off`, and `GOTOOLCHAIN=local`. Set module mode to
readonly, preserving a repository's deliberately selected testing flags.
ReleaseKit-owned builds replace ambient `GOFLAGS` with `-mod=readonly` and use
their explicit build arguments; custom validation commands retain their
deliberately configured flags.
Preparation of caches and tools occurs separately. These settings do not
sandbox arbitrary repository callbacks or establish a general network firewall.

Build with `CGO_ENABLED=0`, `-mod=readonly`, `-trimpath`, `-buildvcs=false`, and
linker flags `-s -w` plus the shared version injection. This selects the pure-Go
build convention already used by the current asset builders. Additional cgo
toolchains remain outside this implementation. The injected string must use a
linker-supported initializer. [Go's linker documentation](https://pkg.go.dev/cmd/link)
defines the `-X` mechanism.

Initially verify linux/amd64, linux/arm64, and darwin/arm64. Represent targets
as values rather than a closed enum; other explicit Go OS/architecture pairs
can be passed to the prepared compiler and may fail according to its support.
This establishes no native-execution promise for other platforms.

Asset names are `<binary-name>-<version>-<goos>-<goarch>`, with `.exe` when the
requested Go OS needs it. Binary names and target components must be nonempty
filename components without path separators, backslashes, CR, or LF, so names
stay in the output directory and have unambiguous manifest entries. Normalize
repeated target pairs to one target, retaining their first position. Distinguish
the display product name used by notes from this binary name. Preserve selected
target order for progress; generate manifests in filename order.

For nonempty targets, invoke the built application with `version` and require
`<binary-name> <version>` plus a final newline. Reuse a target artifact when it
matches `GOHOSTOS/GOHOSTARCH`; otherwise build a temporary native executable
with the same flags and injection. Determine the host independently of ambient
`GOOS/GOARCH`. Native smoke binaries are temporary and are not extra assets.
An empty target set performs no Go build or version invocation. Source-only
projects may retain an explicitly selected application check; no binary check
is silently imposed on them.

Candidate build checks use a temporary output directory outside the worktree
and discard it. Artifact builds record the commit, version, main package,
targets, compiler identity, and generated filename/hash pairs. Return these
facts in `BuildResult`. The CLI persists them in an internal local receipt,
`.releasekit-build.json`, alongside the generated files after a successful
complete build and smoke check. A partial build returns progress without a
receipt authorizing delivery. This receipt is for tool coordination, with no
public format or attestation promise. It contains no credentials and is not a
hosted asset. Build output defaults to `dist`; create
the directory as needed, regenerate owned local filenames, and preserve
unrelated files. Report generated files on partial local failure and clean up
only tool-owned temporary paths.

Delivery uses a clean checkout whose HEAD equals the selected local tag's peeled
commit; detached HEAD is valid. Read the note from that commit and snapshot the
selected settings. Repository-local tracked profiles come from that source;
explicit caller-supplied settings are identified in the build result. Verify
the hosted repository already has the same tag targeting that commit before
creating a release. Existing lightweight historical tags may be inspected and
delivered; new publication follows the annotated-tag standard. Do not require
current remote `main` to remain at an old release commit during delivery retries.

The CLI's `deliver --assets DIR` consumes a verified build receipt and checks
file hashes, selected filenames, and source/build-input identity before remote
mutation. When no directory is supplied, build into a temporary directory from
the tagged checkout and then deliver. With zero targets, optional hosted delivery
creates a note page without a binary manifest. Neither mode reruns the candidate
test suite or changes source-publication status.

### Hosted delivery and Woodpecker

Use a small internal standard-library Gitea REST client. On 2026-10-05 the host's
[version endpoint](https://gitea.maximumdirect.net/api/v1/version) reported Gitea
1.25.4; its [served API schema](https://gitea.maximumdirect.net/swagger.v1.json)
confirmed release-by-tag lookup, JSON release creation, asset listing, and
multipart attachment upload. Consult the host's schema during implementation;
record used operations in the integration guide. This observation is not an
all-version Gitea compatibility promise.

Read the tag through `/api/v1/repos/{owner}/{repo}/tags/{tag}` and verify its
`commit.sha`. Use the repository API prefix for each following operation. Find
the release through `/releases/tags/{tag}`. Create it through
`POST /releases` with the existing tag, captured commit, title from the note's
H1, complete committed note as body, and stable, non-draft settings. A found
release must match the note body and tag and be stable/non-draft; retain its
existing title, including a historical title chosen by other tooling. A content
conflict is reported; its body, title, assets, and tag are not edited. Existing
historical pages remain intact.

List attachments through `/releases/{id}/assets`. Identify expected filenames
and stream their downloads to compare SHA-256 content; size and name alone do
not prove a match. Use multipart field `attachment` and the filename query
parameter for missing uploads. The client obtains no automatic tag-creation
responsibility. Keep authorization on the configured service origin when
following attachment URLs or redirects; never include token values in receipts
or diagnostics.

For nonempty binary sets, generate `SHA256SUMS` with lowercase hashes, two spaces,
filenames, and LF-terminated lines, sorted by filename. It describes the complete
declared binary set and excludes itself and the private receipt. An existing
manifest must match that expected content. Fill missing assets covered by that
manifest only with matching bytes. A manifest describing a different or smaller
set cannot be replaced to extend that version. Leave unrelated attachments
untouched.

Inspect all known declared asset and manifest conflicts before uploading.
Upload missing binaries in filename order, then a missing manifest. HTTP writes
are separate operations. After an ambiguous creation or upload, re-read the
affected resource once; classify matching content as completed, conflict as
conflict, and inaccessible or still-indeterminate content as unknown. Handle
concurrent creation by finding and verifying the created resource. Do not
blindly retry writes or delete attachments. Record partial progress so an
operator can rerun against the same tag and retained assets.

Woodpecker uses tag-triggered repository-local YAML with a pinned Go/tool image
and a pinned ReleaseKit source install. Provide an example using an official Go
image plus a separate provisioning step that installs ReleaseKit from its
immutable release pin and prepares consumer module caches. Build and deliver
then run with offline Go execution. This honors ReleaseKit's source-only initial
distribution; a dedicated ReleaseKit container image would require a separate
deliverable decision. Use the repository's selected Go toolchain image, which
must satisfy its own module requirements.

Use `CI_COMMIT_TAG` and `CI_COMMIT_SHA` to bind the workflow to tagged source,
with an explicit tag fetch when the checkout omits local tag refs. The build step
writes to ignored `dist`; the delivery step shares the workspace and supplies
the Gitea token from a Woodpecker secret. Pin actual image digests and source
versions when adopting the example. Pipeline preparation may access dependency
services; candidate validation and builds use the prepared caches. CI does not
call `publish`, push refs, or gate source completion. The supported retry is a
rerun from the same tagged source with content comparison; reproducible bytes
across arbitrary toolchains or elapsed time are not promised.

## Stage 1: Establish the Go module and development baseline

Status: Pending. Depends on the baseline only.

1. Add the module with the selected path and language baseline. Add root package
   documentation for the orchestration facade and establish ordinary Go layout.
2. Keep committed module state independent of sibling checkouts and workspaces.
   Start without external runtime dependencies or a generic plugin framework.
3. Add the working offline developer test command and initial implemented-package
   inventory. Update README to its actual implemented boundary.

Acceptance: module loading and `go test ./...` work with the prepared local
toolchain and network disabled. Review module identity and licensing notices.
Do not invent tests merely to assert that an empty package exists.

## Stage 2: Implement the runtime version facade

Status: Pending. Depends on Stage 1.

1. Implement `buildinfo.Version` and its internal injected-string and main-module
   fallback logic. Keep runtime state private and the public accessor small.
2. Add the internal injection-symbol contract without importing orchestration
   into the runtime path. Test injected precedence and missing/development
   metadata through stable internal seams and a small executable fixture.
3. Add `cmd/releasekit` with a working `version` command using this accessor.
   Record its implemented command contract and the runtime consumer guidance.

Acceptance: a source-built fixture reports `dev`; a fixture linked with a stable
version reports that version. Fallback metadata uses the executable main module.
CLI version output is correct and no runtime orchestration initialization occurs.

## Stage 3: Protect public contracts and dependency direction

Status: Pending. Depends on Stage 2.

1. Add a compiled-export boundary checker for both facades using `go list` export
   data and `go/types`. Inspect exported signatures, fields, callbacks, aliases,
   generic constraints, and pointer/value method sets recursively.
2. Assert facade ownership of public named types. Permit deliberately selected
   standard-library contracts. Protect the private-state forwarding approach
   against leaked internal types and promoted implementation methods.
3. Add import-direction checks: internal production packages use internal
   contracts; the runtime facade's dependency closure excludes orchestration,
   process, build, Gitea, and CLI implementation.
4. Use small negative fixtures proving that the checker catches a leaked type
   and promoted internal method, and accepts a private implementation field.

Acceptance: actual exports pass and meaningful negative fixtures fail. Tests
inspect contracts and imports, with no fixed inventory of future internal
package names. Extend these checks as subsequent exports land.

## Stage 4: Implement profile loading and command adaptation

Status: Pending. Depends on Stage 3.

1. Implement JSON product, remote, and command settings under an internal CLI
   adapter. Add strict field decoding, directory resolution, required-value
   diagnostics, direct argument execution, and per-child environment overlays.
2. Implement an internal cancellable process runner with directory, argument,
   environment, stdout, stderr, and exit-error support. Use `os/exec` directly;
   expose no public runner abstraction solely for test assembly.
3. Add CLI parsing infrastructure and selected usage/exit behavior. Advertise
   commands only when their following stages implement them.
4. Add small profile examples and `docs/config.md` for implemented fields.

Acceptance: paths and arguments containing spaces remain separate arguments;
selected environment values reach the child without changing process globals;
missing executables, invalid configuration, and cancellation report useful
errors. Tests use controlled local child commands and temporary directories.

## Stage 5: Capture and validate one local candidate

Status: Pending. Depends on Stage 4.

1. Implement stable-version syntax, clean `main` and index/worktree inspection,
   captured HEAD, profile snapshot/note loading, title identity, and unused local
   tag checks. Preserve immutable candidate facts in internal values.
2. Implement default offline Go validation and callback adaptation. Bind the
   callback to the captured candidate; pass captured version/commit to CLI
   commands. Call the complete validation callback once, stopping on failure.
3. Recheck branch, HEAD, and cleanliness after validation. Retain the captured
   settings throughout the operation. Implement the public `Check` operation
   and local diagnostic `check` command.
4. Document that local check success provides local candidate evidence and makes
   no authoritative remote availability claim.

Acceptance: temporary repositories cover invalid versions, missing or mismatched
committed notes, dirty tracked/untracked state, existing local tags, detached
HEAD, callback failure, and a callback changing HEAD or the worktree. Count a
successful callback once. No test needs a publication service, and `Check`
creates no tag or remote ref.

## Stage 6: Resolve and inspect the authoritative endpoint

Status: Pending. Depends on Stage 5.

1. Implement effective push-URL capture, command-scoped remote configuration,
   matching read/write resolution, and endpoint rechecks described above.
2. Implement exact remote main/tag queries with distinct present, absent,
   conflicting, and unreadable results. Query failures never establish absence.
3. Compose the pre-validation and pre-publication remote guards around captured
   local state. Require main equality, rather than ancestor-only publication.

Acceptance: local remotes cover a separate fetch endpoint, explicit push URL,
ordinary URL rewrites, multiple push destinations, missing main, conflicting
tags, main ahead/behind the candidate, endpoint changes, and remote failure.
Queries leave local tags, persistent remote configuration, and remote refs intact.

## Stage 7: Create and push the exact annotated tag

Status: Pending. Depends on Stage 6.

1. Implement public publication request/result values and explicit conversion
   into the engine. Validate once between the complete preflight guards.
2. Create an annotated tag from captured note bytes, inspect type and peeled
   commit, capture its object ID, and push only that object to the selected ref.
3. Recheck mutable local state and endpoint before the push, including the local
   tag still identifying the captured object. A changed local tag prevents this
   invocation from proceeding; cleanup remains deliberate recovery.
4. On successful push, return published state without another remote read-back.
   On push error, retain the tag and return unknown until Stage 8 adds resolution.

Acceptance: a local bare remote receives the expected tag object and commit;
its main and unrelated refs do not change. Follow-tags and mirror configuration
cannot expand publication. Note content, tag identity, and one-validation
behavior are checked through the public facade. Restrict stage trials to test
remotes while failure handling is incomplete.

## Stage 8: Resolve rejected and ambiguous publication

Status: Pending. Depends on Stage 7.

1. Add the one-query reconciliation path and public error/result classification.
   Preserve the original push cause when resolution does not confirm success.
2. Give post-push cancellation a separate bounded recovery context. Retain local
   tag/object facts when the read fails or recovery is cancelled/times out.
3. Add real rejected-push tests using bare-remote hooks. Simulate lost
   acknowledgments at the subprocess boundary after a real successful push.
   Separate known absence, conflicting object, and unavailable-query cases.
4. Cover a remote branch change during validation and local tag mutation before
   push. Keep concurrency promises at the observed guard boundaries.

Acceptance: exact remote object match succeeds despite a reported push error;
missing, conflicting, and unavailable remote tags have distinct outcomes. Failed
pushes issue one reconciliation query, successful pushes issue none, and no
recovery force-update or automatic tag deletion occurs.

## Stage 9: Expose publication and document ReleaseKit bootstrap

Status: Pending. Depends on Stage 8.

1. Wire the complete public publisher into `releasekit publish`, with selected
   progress output, final result, exit classification, and signal cancellation.
2. Add ReleaseKit's source-only profile and one short maintainer entry script.
   The profile selects the offline default suite; no inherited race, lint,
   documentation, image, or platform gates are added.
3. Create `docs/release.md` now that publication works. Name authoritative
   `origin` at the ReleaseKit forge URL and `main`; document preparation,
   successful-push completion, exact-object recovery, local tag retention, and
   deliberate cleanup of proven unpublished tags.
4. Document first-release execution from the captured candidate source using
   the local Go toolchain, before a released ReleaseKit executable exists.
   Include immutable release-note licensing footer construction and dependency
   preparation separate from validation.
5. Update current development documentation and the policy-adoption roadmap's
   bootstrap status to the implemented boundary. Preserve pending deliverables.

Acceptance: an end-to-end CLI fixture publishes to a local remote through a
committed profile and returns the expected exit/output behavior. Runbook commands
are exercised using a temporary repository configured like ReleaseKit. This
stage prepares self-publication and does not publish a real ReleaseKit release.

## Stage 10: Build selected targets with shared version injection

Status: Pending. Depends on Stage 9.

1. Implement public build values and internal build execution using the fixed
   flags, version symbol, filename convention, and prepared Go environment.
2. Build explicit OS/architecture pairs and verify the application `version`
   invocation using a host artifact or temporary native build. Preserve
   caller-owned output files and report partial generated output on failure.
3. Return source identity, artifact paths, filenames, targets, hashes, and
   compiler identity. Keep byte reproducibility and cross-platform execution
   promises outside the result contract.
4. Add a temporary consumer module importing only `buildinfo` and exposing the
   canonical version command. Its local replacement is fixture-only.

Acceptance: the fixture compiles for the three initial targets and a native
execution reports the injected version. An ambient cross-target environment
does not select the smoke host. Empty targets perform no build or smoke test;
missing main packages, build failures, incorrect version output, unsafe binary
names, and cancellation fail with useful partial results.

## Stage 11: Integrate candidate builds and artifact command

Status: Pending. Depends on Stage 10.

1. Add build profile fields, CLI `build`, and the private artifact receipt.
   Bind receipts to source/build-input identity and generated hashes. Validate
   data on reload; leave the receipt outside the public API and hosted asset list.
2. Integrate selected builds into `Check` and `Publish` after the single candidate
   callback. Use disposable output outside the worktree for candidate builds.
   Recheck mutable state after the entire validation/build sequence.
3. Add ignored `dist` output and source-only and binary-producing examples.
   Document the API, profile target selection, version invocation, and build
   output ownership.
4. Refresh facade and runtime dependency checks with the new values.

Acceptance: source-only publication invokes no builder; selected build failure
prevents tag creation; selected builds inject the exact candidate version;
callback validation runs once. CLI artifacts and receipts agree on filenames,
hashes, commit, and resolved build settings. Generated validation output does
not dirty the candidate. This completes the first source-publication/build
capability slice.

## Stage 12: Pilot publication in PromptKit

Status: Pending. Depends on Stage 11 and a reachable immutable tool pin.

1. Review PromptKit's current instructions, release policies, and entry scripts.
   Add a source-only profile using its actual note display name, currently
   `Promptkit`. Keep its application-specific consumer example checks and other
   deliberately adopted candidate gates in its validation command.
2. Replace repeated release guards and tag publication with a short ReleaseKit
   invocation. Move note identity validation to ReleaseKit; remove extra shared
   note-section requirements only through the corresponding local policy change.
3. Update installation prerequisites, local release wiring tests, and maintainer
   documentation. Retain no duplicate mandatory pre-check before publication.

Acceptance: isolated repository fixtures exercise the new wrapper and profile
against a local remote, preserve source-only behavior, and run the selected
candidate checker once. PromptKit's own suite passes. Record deleted shared
mechanics separately from retained product checks. No Go runtime dependency or
hosted page is introduced for this library.

## Stage 13: Pilot publication in Scriptorium

Status: Pending. Depends on Stage 12.

1. Adapt Scriptorium's publication entry point and release policy to the common
   profile/command. Preserve its selected candidate test flags and genuinely
   product-owned checks in a small local candidate command.
2. Retain its existing candidate build check temporarily: its application has
   no canonical runtime version command yet. Document that shared builds are
   deferred to Stage 19; the existing delivery pipeline continues meanwhile.
3. Transfer exact-object publication/failure tests into shared coverage and
   retain a small wrapper/configuration test locally. Update its runbook.

Acceptance: local-remote fixtures confirm common publication and bounded
recovery without changing the existing asynchronous deliverables. Scriptorium's
own suite passes. The two pilots substantiate the same public facade with
different product checks and endpoint configurations.

## Stage 14: Find and create Gitea release pages

Status: Pending. Depends on Stage 13.

1. Implement the small internal REST transport using the served API operations,
   explicit destination/token inputs, context cancellation, and structured
   failure mapping. Use standard HTTP and JSON packages.
2. Verify the hosted tag targets the captured source commit. Find a release by
   tag, create a missing stable release from the committed note, and verify
   existing note body/tag and stable, non-draft state before accepting it.
   Preserve the existing title.
3. Handle create conflicts and lost acknowledgments by one lookup and content
   comparison. Never edit the existing page to make it match.
4. Add `docs/integrations/gitea.md` describing implemented API interactions,
   credential supply, source binding, and failure semantics.

Acceptance: `httptest.Server` covers found, missing, created, conflicting,
unauthorized, malformed, cancelled, and ambiguous-create results. A missing or
wrong hosted tag prevents page creation. Existing historical titles are retained
when the body, tag, and release state match. Fixture assertions cover actual
request paths, payloads, and authentication without using real credentials.

## Stage 15: Inspect asset and manifest content

Status: Pending. Depends on Stage 14.

1. Generate the expected binary manifest from the declared build result. Add
   attachment discovery and streaming hash comparison of existing assets.
2. Compare existing `SHA256SUMS` with the complete declared manifest. Identify
   matching, missing, conflicting, and unverifiable content separately.
3. Inspect all declared conflicts before any upload and preserve unrelated
   attachments. Keep download authorization confined to the configured origin.

Acceptance: equal name/size with different bytes is conflict; matching content
is accepted; a full matching manifest can cover missing binaries; a subset or
different manifest is conflict; unreadable content is not treated as missing.
Source-only delivery generates no binary manifest. No write endpoint is used
by inspection tests.

## Stage 16: Upload missing assets and report partial delivery

Status: Pending. Depends on Stage 15.

1. Add multipart uploads for missing binaries in filename order, followed by a
   missing manifest. Record completed work and pending asset identities.
2. Resolve ambiguous uploads by one resource read and content comparison.
   Handle concurrent matching uploads without creating replacement content;
   detect duplicate/conflicting attachment names as conflicts.
3. Implement rerun behavior that accepts existing matching files, adds missing
   ones, and stops on conflicts. Preserve every existing page and attachment.
4. Add tests where the first binary succeeds, a later write fails, and a second
   invocation completes only the missing assets; also cover a lost manifest
   acknowledgment and failure of the reconciliation read.

Acceptance: partial and unknown outcomes retain exact completed/pending facts;
retries do not overwrite or delete content; no blind repeat POST is made after
an ambiguous acknowledgment. Published manifest constraints hold across reruns.

## Stage 17: Expose tagged-source delivery through the facade and CLI

Status: Pending. Depends on Stage 16.

1. Implement `Deliver`, its facade-owned request/result values, and conversions.
   Bind source note, resolved build settings, tag commit, and hosted repository
   as specified.
2. Add delivery profile fields, environment-name token loading in the CLI, and
   `deliver` with an optional verified assets directory. With no directory,
   build tagged-source artifacts in temporary storage before uploading.
3. Accept detached tagged checkouts and historical tags without requiring old
   remote main equality. Verify receipt identity/hashes before supplied assets
   are used. Keep the library credential input explicit.
4. Add current consumer/CLI guidance for source status, delivery status,
   retained assets, and retry commands. Extend public boundary checks.

Acceptance: a facade/CLI end-to-end fixture builds tagged source and delivers to
a local server; a rerun is content-aware. Wrong commit, stale build settings or
receipt, tampered assets, and missing credentials prevent relevant writes. Candidate
tests and Git publication are not run by delivery. A delivery failure leaves
the existing source tag intact and reports only delivery failure.

## Stage 18: Provide the common Woodpecker integration

Status: Pending. Depends on Stage 17 and the delivery-capable tool pin.

1. Add a maintained example tag pipeline using a pinned Go image, explicit
   ReleaseKit source installation and cache preparation, artifact build, and
   delivery with the configured secret. Explain how consumers pin their image
   and tool source; create no new ReleaseKit image-distribution requirement.
2. Bind tag and commit variables to the checkout, fetch the selected tag when
   necessary, share generated assets between steps, and keep output ignored.
3. Document preparation versus offline execution, asynchronous status, and
   rerunning the same immutable tag. The workflow executes no publisher.
4. Exercise its shell command sequence locally against a fixture and local
   server. Verify YAML with an available supported Woodpecker validator when
   available; report that live runner behavior remains unverified otherwise.

Acceptance: the maintained commands reach common build/delivery operations with
the selected version and commit, and secrets enter only the delivery step.
Static/manual YAML review and local command evidence are recorded accurately.
CI success is not a source release gate. The
[Woodpecker environment reference](https://woodpecker-ci.org/docs/usage/environment)
owns the runner-provided tag and commit variables.

## Stage 19: Standardize Scriptorium runtime information and builds

Status: Pending. Depends on Stage 18 and a released runtime dependency pin.

1. Add the `buildinfo` dependency and canonical `scriptorium version` command
   before configuration/provider initialization. Use graph discovery to locate
   its CLI boundary; the earlier implementation has no release version command.
2. Set main package `./cmd/scriptorium`, binary name `scriptorium`, and its
   existing Linux amd64/arm64 asset targets in the profile.
3. Replace the temporary local candidate build loop from Stage 13 with shared
   candidate builds. Retain only product checks and a small version/wiring test.
4. Update current CLI contracts and compatibility impact documentation.

Acceptance: shared builds report the injected version without credentials or
service access. The unchanged two-asset selection is used for candidate checks.
Runtime dependency checks show the application needs only `buildinfo` for this
responsibility; its ordinary suite passes.

## Stage 20: Pilot common delivery in Scriptorium

Status: Pending. Depends on Stage 19.

1. Replace its duplicated Woodpecker build loop and release-plugin step with the
   common example adapted to its pinned Go/tool versions and Gitea destination.
2. Keep the committed note as the hosted body and maintain the existing two
   Linux assets and checksum deliverable. Add ignored local build output.
3. Remove its repeated asset builder code once local fixture evidence exercises
   common build and retry delivery. Update its delivery runbook and tests.

Acceptance: local fixture execution verifies first delivery, matching rerun,
partial delivery recovery, and conflicting bytes. The repository's source
publication path waits for no CI or attachments. Record live activation as a
separate maintainer action; preserve historical release workflows at old tags.

## Stage 21: Migrate ConfigKit publication

Status: Pending. Depends on Stage 20.

1. Add a source-only profile and wrapper using the common publisher. Its current
   sequential main/tag publication becomes main-first preparation and tag-only
   publication. Update the adopted policy and maintainer runbook together.
2. Preserve its existing selected baseline-toolchain, test, vet, and build
   checks in its candidate checker where its local policy justifies them.
   These remain ConfigKit checks, not ReleaseKit-wide requirements.
3. Remove duplicated ref checks, annotated-tag creation, and push recovery.
   Retain a small profile/wrapper test and run its suite.

Acceptance: a local fixture refuses publication until authoritative main equals
the candidate, then publishes only the tag with one candidate-check invocation.
ConfigKit gains no runtime import, hosted page, or distributed binary.

## Stage 22: Migrate Notarius publication

Status: Pending. Depends on Stage 21.

1. Add a source-only profile and common publication wrapper. Its existing
   branch push and lightweight tag become prepared main plus annotated tag.
   Update the adopted policy and procedure with that deliberate change.
2. Retain its existing explicit host version check temporarily in its local
   checker. Remove repeated common release guards and shared publication tests.
3. Preserve a small wrapper/check invocation test and verify ordinary behavior.

Acceptance: local remotes demonstrate the new publication approach and bounded
recovery. Source-only deliverables and the current version-check prerequisite
remain unchanged until the next stage.

## Stage 23: Standardize Notarius runtime version access

Status: Pending. Depends on Stage 22 and a released runtime dependency pin.

1. Replace its private override/resolution mechanism with `buildinfo`. Preserve
   its existing `--version` invocation and add the canonical `version` command
   for common smoke checks, with `notarius <version>` output.
2. Document the common metadata/`dev` fallback and its deliberate effect on any
   existing unversioned-build diagnostic behavior. Update owned tests/contracts
   rather than silently preserving obsolete private override assumptions.
3. Replace the explicit host check's private linker flags with a small local
   invocation of the shared Build API for the host target. This remains an
   explicitly selected local check, not a distributed target declaration.
   The API accepts explicit host Go targets as described above.

Acceptance: both version invocations report the same injected value without
configuration or credentials, and the deliberate source-build behavior is
covered. The source-only profile still has no automatic binary targets or Gitea
page; the separately selected host check runs once with its candidate checker.

## Stage 24: Migrate Audita publication

Status: Pending. Depends on Stage 23.

1. Replace atomic main/tag publication with main-first preparation and the
   common annotated-tag publisher. Retain its `--check` user entry by mapping it
   to common local `check`; map `--publish` to common publication.
2. Preserve current tests and its existing builder temporarily as selected
   candidate checks. Update the local release policy and completion wording.
3. Transfer shared atomic/lightweight publication tests to the common contract,
   retaining tests of the Audita command mapping and local checks.

Acceptance: diagnostic mode performs no remote publication; publication refuses
an unprepared main and uses an annotated tag. The configured candidate sequence
runs once and existing asynchronous Linux deliverables remain selected.

## Stage 25: Standardize Audita runtime information and builds

Status: Pending. Depends on Stage 24 and a released runtime dependency pin.

1. Add `audita version` using `buildinfo`, before application configuration and
   provider initialization. The earlier CLI has no release-version accessor.
2. Declare `./cmd/audita`, binary name `audita`, and linux/amd64 plus linux/arm64.
   Replace `scripts/build-release.sh` mechanics with shared candidate/build
   operations and retain product-owned tests.
3. Add a small application version-command test and update current contracts.

Acceptance: native smoke verifies the injected tag and needs no credentials;
both existing Linux assets retain their names/target selection. Audita's own
suite passes and duplicate candidate build work is removed.

## Stage 26: Migrate Audita delivery

Status: Pending. Depends on Stage 25.

1. Adapt the common tag workflow to Audita's pinned image/tool, Gitea repository,
   and secret name. Replace release-plugin skip-by-name behavior with shared
   content verification and additive delivery.
2. Update delivery/retry documentation and remove unused build wrapper code.

Acceptance: local first-run, rerun, conflicting-content, and partial-delivery
fixtures exercise the actual configured filenames and complete manifest. Source
completion and live activation remain separate from delivery verification.

## Stage 27: Migrate Narratio publication

Status: Pending. Depends on Stage 26.

1. Retain main-first preparation and replace lightweight tags with common
   annotated publication. Adapt its candidate checker and release entry point,
   keeping its selected product checks and build mechanics temporarily.
2. Update policy/runbook and retire common version/note/ref helpers where their
   behavior is now shared. Preserve remaining helper uses until Stage 28.

Acceptance: local publication fixtures cover exact candidate/tag identity and
common recovery; the checker runs once. Narratio retains its three declared
asset targets and existing delivery pipeline until subsequent stages.

## Stage 28: Standardize Narratio runtime information and builds

Status: Pending. Depends on Stage 27 and a released runtime dependency pin.

1. Replace its private buildinfo variable with the facade in its existing
   `narratio version` command. Preserve output shape and update tests to use
   supported behavior rather than mutating a private version variable.
2. Declare `./cmd/narratio`, binary name `narratio`, and linux/amd64,
   linux/arm64, darwin/arm64. Use the prepared toolchain required by its module.
3. Replace `build-release-assets.sh` flags, host smoke, and target loop with
   shared builds. Remove duplicate build invocation from its candidate checker.
   Preserve product checks and remove helpers that now have no remaining use.

Acceptance: the native version probe and all three cross-builds pass; foreign
platform compilation is reported without a native-execution claim. A nonempty
caller output directory can retain unrelated files, and no broad recursive
cleanup is inherited from the former builder.

## Stage 29: Migrate Narratio delivery

Status: Pending. Depends on Stage 28.

1. Replace its release plugin and repeated tag-pipeline candidate validation
   with the common prepared build/delivery workflow. Candidate validation belongs
   to source publication; tagged delivery does not repeat it as a gate.
2. Keep its three binary assets, committed note, Gitea destination, and complete
   checksum manifest. Adapt pinned images and tool versions to its Go baseline.
3. Update retry documentation and small repository-local integration checks.

Acceptance: fixture workflow evidence verifies all three filenames, full
manifest, matching rerun, and partial/ambiguous delivery. Existing historical
tags/pages/assets are untouched and source publication waits for no delivery.

## Stage 30: Audit the completed target state and documentation

Status: Pending. Depends on Stage 29.

1. Map each feature-roadmap responsibility to its implemented owner and tests.
   Verify both public facades, source-only behavior, candidate checks, exact
   publication, runtime injection, selected targets, hosted content verification,
   partial recovery, and Woodpecker integration against current source.
2. Review the six migrations against both architecture success criteria: shared
   infrastructure was removed and one coherent model was adopted. Count actual
   removed scripts/tests, retained product checks, and new ReleaseKit code
   separately; do not present the historical estimate as measured savings.
3. Check current documentation owners, links, examples, dependency attribution,
   license texts, and maintainer runbooks. Record live integration verification
   separately from local acceptance, including anything awaiting activation.
4. Update feature status and this plan from evidence. Retire completed execution
   details during release preparation while preserving target intent, deferred
   decisions, and useful navigation.

Acceptance: each roadmap responsibility has direct source and behavioral
evidence, each migrated repository retains only justified product checks and
small wiring coverage, and no unimplemented or unverified responsibility is
marked complete. Run affected suites according to their policies; add no new
permanent release matrix or synchronization gate.

## Open Questions

The core implementation choices above are complete for the recommended design.
These maintainer decisions affect adoption and live use; do not fill in unknown
release pins or silently broaden deliverables.

### Which immutable ReleaseKit versions should consumers pin?

Required before Stage 12, and refreshed before Stage 18 and runtime migrations.

**Recommended:** publish a first source release such as `v0.1.0` after Stage 11,
then a delivery-capable source release after Stage 17. Verify version availability
at preparation time and use the actual published pins in profiles' accompanying
installation instructions, CI provisioning, and application module dependencies.
This gives the publication pilots an early usable tool and lets later delivery
and runtime adopters depend on documented versioned contracts. Publication is a
separate maintainer-authorized action under the release policy.

**Viable alternative:** make immutable source-commit/pseudo-version pins available
for the pilots and publish the first numbered release after Stage 17. This
supports integration feedback before a numbered release, at the cost of more
operator bookkeeping and less friendly installation instructions. Neither
approach commits local checkout replacements or claims an unpublished version
exists. Record the selected pins here before dependent migration stages proceed.

### Should source-only projects also receive hosted Gitea release pages?

This decision is required only if adopting pages for PromptKit, ConfigKit,
Notarius, or ReleaseKit; their current plan stages preserve source-only delivery
without hosted-page requirements.

**Recommended:** retain their existing delivery scope initially. Support explicit
zero-asset hosted delivery in ReleaseKit, while using the three existing binary
publishers to establish its behavior. This meets the requested standardization
without adding credentials, CI operations, or a new deliverable to other projects.

**Viable alternative:** declare a hosted note page for every project, with zero
binary assets where appropriate. This gives uniform forge presentation and uses
the same delivery API, but needs deliberate local release-policy changes,
credentials, and responsibility for retries. If selected, add a small adoption
stage for each affected project before completing Stage 30.
