+# lint-spx.9 — RELEASE-NOTES-0.6.0.md: boundary fixes and graph schema 0.2.0
+
+Own stack rooted on `develop` (`gh stack link --base develop`). Docs only:
+`release/RELEASE-NOTES-0.6.0.md` and this record. `requirements` is empty
+because no requirement is implemented; say so in the closeout.
+
+## Source of facts
+
+Every sentence added must be traceable to one of: a merged PR listed below
+(`gh pr view <n> --json title,body`), a sprint doc under
+`docs/plans/release-0.6.0/`, or the code at `origin/develop`. No sentence
+about behaviour that you did not read in the diff or a sprint doc.
+
+Merged to `develop` on 2026-09-20 since the 2026-08-30 note:
+
+- boundary inventory stack: #115, #168, #171, #173, #175, #176, #177, #178
+- trait identity stack: #159, #160, #163, #164
+- installer test redesign: #180
+- CI on every PR target: #182
+- orchestration tooling (`.claude/**` only, not user-facing): #166, #167,
+  #170, #174, #179, #181 — one line under a "Repository tooling" heading at
+  most; do not describe skills.
+
+## Deliverables
+
+1. `## Release`: date refreshed to the day you commit; keep the other fields.
+2. `## Summary`: one added paragraph: boundary-model fixes and graph schema
+   `0.2.0`.
+3. `## Major Changes`, new bullets (one each, with PR numbers):
+   - reference impl owners without graph identity collisions (#159);
+   - trait methods distinguished from inherent methods and qualified forwarding
+     edges (#160, #164);
+   - boundary graph `schema_version` `0.1.0` → `0.2.0`
+     (`crates/sc-lint-boundary/src/lib.rs:42`, #163);
+   - structured boundary inventory: strict forbidden-edge deserialization,
+     required `planning.toml`, `owner_crate_path` check, preserved edge parse
+     causes, Python validator parity (#115, #168, #171, #173, #175–#178).
+4. `## Migration Notes`: the schema `0.2.0` rebaseline: what a consumer with a
+   committed `0.1.0` graph must do. Read #163's diff and the boundary docs for
+   the actual procedure; if none is documented, write the exact command
+   sequence you verified against the code and cite `file:line`.
+5. `## Validation`: replace the Phase G sentence with the CI facts of the
+   merges: `develop` head SHA, and `gh run list --branch develop --limit 1`
+   status.
+6. `## Follow-Up Items`: keep; add the installer ETXTBSY redesign (#180) as a
+   test-only change under a `## Test Infrastructure` or similar heading rather
+   than Major Changes.
+7. Do not edit the `## Included Crates` block (generated).
+
+## Acceptance criteria
+
+- `gh stack view --json` first and last; summary in the closeout.
+- PR ready for review (never draft), base `develop`, in its own stack.
+- `just lint`, `git diff --check` exit 0; `gh pr checks <pr>` counts + run id.
+- `git diff --name-only` lists only the two files.
+- Closeout: one line per deliverable with the fact source (PR number or
+  `file:line`). `status: complete`.
+- Completion message, then wait for the lead's reply before closing.
+
+## Closeout
+
+- Deliverable 1: `release/RELEASE-NOTES-0.6.0.md:5` refreshes the release date
+  to `2026-09-20`; source: task date and PR #189.
+- Deliverable 2: `release/RELEASE-NOTES-0.6.0.md:13-16` adds the boundary and
+  graph-schema summary; sources: PRs #159, #160, #163, #164 and boundary
+  sprint docs.
+- Deliverable 3: `release/RELEASE-NOTES-0.6.0.md:36-49` adds the four major
+  change bullets with PR/file sources; sources: PRs #115, #159, #160, #163,
+  #164, #168, #171, #173, #175–#178.
+- Deliverable 4: `release/RELEASE-NOTES-0.6.0.md:60-69` records the `0.1.0`
+  to `0.2.0` rebaseline sequence; source: `docs/sc-lint-boundary/graph-schema.md:18-43`,
+  PR #163.
+- Deliverable 5: `release/RELEASE-NOTES-0.6.0.md:73-76` records develop head
+  `e2477c38857537c8bcd34cf3873ee9726ef8d12a` and successful run
+  `35535212640`; source: `git rev-parse origin/develop` and `gh run list`.
+- Deliverable 6: `release/RELEASE-NOTES-0.6.0.md:95-99` records installer
+  fixture redesign PR #180; source: PR #180 and the accepted installer sprint
+  record.
+- Deliverable 7: `git diff --name-only origin/develop...HEAD` lists only
+  `release/RELEASE-NOTES-0.6.0.md` and this sprint doc; source: command output.
+- PR #189 is ready, based on `develop`, and `gh stack view --json` reports one
+  layer with `needsRebase=false`; `just lint`, `just test`, and
+  `git diff --check` exit 0. PR #189 CI run `35559945150` was observed as
+  `0 pass / 12 pending / 0 fail`.
