+# V18 Post-Merge Release Handoff
+
+## Hill
+
+Record the state after the release-prep PR merged and make the remaining
+`v18.0.0` release work explicit: tag and publish from `main`, with no new
+runtime promise added on a follow-up branch.
+
+## Context
+
+PR #107 merged the `18.0.0` metadata, release notes, release-prep evidence,
+and technical teardown to `main`. The package line is release-ready in source,
+but the public release is not complete until the tag and publish artifacts are
+cut from merged `main`.
+
+The follow-up branch exists to cleanly bookkeep that handoff and set the next
+engineering goalpost. It must not blur three different states:
+
+- `18.0.0` metadata merged to `main`;
+- `v18.0.0` tag created from `main`;
+- npm and JSR artifacts published from that release path.
+
+## User Stories
+
+- As a release manager, I can tell whether the source tree, the Git tag, and
+  the package registries all agree on `18.0.0`.
+- As a maintainer, I can see that the release-prep PR has merged without
+  accidentally treating that as a completed public release.
+- As a downstream operator, I can inspect release notes that describe actual
+  `v18` guarantees without inheriting hidden branch-state assumptions.
+
+## Acceptance Criteria
+
+- `docs/BEARING.md` names PR #107 as merged and `origin/main` as the source
+  of truth for the current branch.
+- The v18 blocker ledger treats PR review, CI, and merge as complete.
+- Tag and publish remain explicitly open until registry evidence exists.
+- No follow-up doc claims that end-to-end graph streaming is part of v18.
+

+- `git rev-parse --short origin/main`

+# V18 Tag And Publish Gate
+
+## Hill
+
+Define the final public-release gate for `v18.0.0` without performing it on a
+feature branch.
+
+## Context
+
+`package.json`, `jsr.json`, workspace package manifests, lockfile metadata,
+and the changelog now agree on `18.0.0`. The release-prep branch passed local
+preflight before merge, and GitHub CI passed before PR #107 merged.
+
+That is necessary but not sufficient. The public release must still be cut
+from merged `main`, and publish evidence must agree with the tag target.
+
+## User Stories
+
+- As a release manager, I can run a short gate before tagging and know which
+  evidence must be attached to the release record.
+- As a package consumer, I can trust that the npm artifact, JSR artifact, and
+  Git tag describe the same source tree.
+- As a maintainer, I do not have to infer whether a feature branch is allowed
+  to publish.
+
+## Acceptance Criteria
+
+- The release gate requires `main` to match `origin/main`.
+- The gate requires `npm run release:preflight` on `main` before tagging.
+- The gate requires the tag target, npm dry-run, JSR dry-run, and published
+  artifacts to agree on `18.0.0`.
+- The gate does not create a tag from a feature branch.
+- The gate preserves the v18 non-claim around full graph streaming reads and
+  writes.
+
+## Test Plan
+
+- `git checkout main`
+- `git pull --ff-only origin main`
+- `npm run release:preflight`
+- `git tag --list v18.0.0`
+- `npm view @git-stunts/git-warp version`
+- JSR package version inspection after publish

+# V18 Release Evidence Archive
+
+## Hill
+
+Name the evidence that should survive after the public `v18.0.0` release,
+instead of leaving it scattered across PR comments, CI logs, and local command
+output.
+
+## Context
+
+The v18 path accumulated several classes of release evidence:
+
+- migration wet-run reports;
+- generated Continuum contract conformance;
+- `warp-ttd` generated-family smoke evidence;
+- closeout audit evidence for raw content/property compatibility boundaries;
+- release preflight output;
+- GitHub CI checks;
+- npm and JSR publish output.
+
+PR comments and CI logs are useful, but they are not a durable release ledger
+by themselves. A release evidence archive should summarize the final public
+facts and point back to inspectable sources.
+
+## User Stories
+
+- As a maintainer, I can answer "what exactly shipped in v18?" without
+  replaying the whole PR history.
+- As a downstream integrator, I can find the migration proof and generated
+  contract evidence that justify the release claim.
+- As a future release agent, I can compare v19 or v20 release evidence against
+  a stable v18 pattern.
+
+## Acceptance Criteria
+
+- A future release archive names the tag, commit, package versions, publish
+  timestamps, and registry artifacts.
+- The archive links to the release-prep PR, CI run, release notes, and local
+  gate evidence.
+- The archive records residual raw content/property compatibility risk as an
+  accepted v18 risk, not an omitted blocker.
+- The archive records that full graph streaming is a later-major goal.
+
+## Test Plan
+
+- Markdown lint the archive.
+- Link-check repository-local release evidence links.
+- Compare archived package versions against `package.json` and `jsr.json`.
+- Verify the archived tag SHA matches the release commit.

+# Post-V18 Storage Retirement Decision
+
+## Hill
+
+Decide whether the next engineering goalpost should continue raw
+content/property storage retirement before starting v19 runtime doctrine work.
+
+## Context
+
+V18 deliberately accepts residual raw content/property compatibility
+boundaries. That is honest, but it is still debt. The closeout audit now
+guards drift, yet the repo still carries legacy compatibility spelling in
+named boundaries.
+
+The competing pressure is v19: observation, admission, and doctrine
+convergence. Starting v19 while storage-plane debt remains visible may be
+reasonable, but only if the debt is boxed and ratcheted tightly enough.
+
+## User Stories
+
+- As a maintainer, I can decide whether storage debt is a release-line risk or
+  a manageable ratcheted backlog item.
+- As a migration operator, I can trust that remaining legacy compatibility
+  boundaries are named and tested.
+- As a v19 planner, I can start observer/admission work without inheriting
+  ambiguous v18 substrate claims.
+
+## Acceptance Criteria
+
+- The decision distinguishes total storage retirement from bounded residual
+  compatibility.
+- The decision identifies the next single raw boundary to retire if retirement
+  continues first.
+- The decision explains why v19 can or cannot start before full storage
+  retirement.
+- The closeout audit remains the executable guard for any deferred boundary.
+
+## Test Plan
+
+- Run the content/property closeout audit.
+- Inspect each allowlisted boundary for ownership and reason.
+- Verify release docs do not claim total raw storage retirement.
+- Update the relevant backlog lane after the decision.
