Follow-up to #435 (Baton half). straymark-core's source scanner and two
CLI walkers also read another checkout nested in the project — a linked
worktree (`.worktrees/<name>/`), a submodule, a nested clone — as the
project's own code: on an adopter repo, `architecture generate` invented
a `.worktrees` component holding a full copy of it.

- core: `walk::is_nested_checkout` (a sub-directory with its own `.git`)
  used by `architecture::collect_source_files` → architecture generate /
  sync / validate, status --where, Loom's architecture view + Intent
  plane, Baton's overlay.
- cli: tree_grep (followups verify --claims, analyze declared-vs-wired)
  and the analyze walker use the same rule.
- baton: reuses the core rule (behavior unchanged, no release).
- straymark-core bound moved to 0.10.1 in cli, loom AND baton together.

+# AILOG: core nested-checkout rule (#434 follow-up)
+
+## Summary
+
+#435 taught Baton's walkers to skip another checkout nested in the project. The same blind spot
+existed in `straymark-core`'s source scanner and in two CLI walkers. The rule now lives once, in
+`core::walk::is_nested_checkout`, and all of them use it. Released as core 0.10.1, CLI 3.49.2 and
+Loom 0.7.1.
+
+## Context
+
+Demonstrated on an adopter repository with one linked worktree under `.worktrees/`. `straymark
+architecture generate`, writing to a scratch `--out`, produced 15 components, one of them
+`.worktrees` (glob `.worktrees/**`): a full copy of the repo, 5606 source files against 5235 in the
+real tree. With this change the same command produces 14 components and no `.worktrees`. The
+repository was read-only in both runs (git status unchanged).
+
+## Actions Performed
+
+1. `core/src/walk.rs`: `pub fn is_nested_checkout(dir)`. A sub-directory with its own `.git` (a
+   file for a linked worktree or submodule, a directory for a nested clone) is another checkout.
+2. `core::architecture::collect_source_files_with` skips such directories. This covers
+   `architecture generate | sync | validate`, `status --where`, Loom's architecture view and
+   Intent plane, and Baton's overlay.
+3. CLI: `tree_grep::walk` (used by `followups verify --claims` and `analyze declared-vs-wired`) and
+   `analysis_engine::walk_recursive` (`analyze`) use the same rule.
+4. Baton: `scan::is_nested_checkout` is now a re-export of the `core` rule. Its behavior is
+   unchanged.
+5. Tests: `core::walk` itself, and one per walker. Each walker test uses a directory name that is
+   not already excluded (the first `analyze` fixture used `vendor/`, which `analyze` already
+   excludes, so it passed without the fix; it was moved to `third_party/`). All three walker tests
+   fail with the guard removed.
+6. Versions move atomically: core 0.10.0 → 0.10.1, and the `straymark-core` bound moves in the
+   CLI, Loom **and** Baton Cargo.toml, per the lesson from #282. CLI 3.49.2, Loom 0.7.1, CHANGELOG
+   and Loom CHANGELOG.
+
+## Decisions Made
+
+- **One rule, in `core`.** Walkers keep their own name lists, because those differ by purpose, but
+  the "another checkout" rule is shared so that no tool can disagree with another about what the
+  project contains.
+- **Patch versions.** The change adds an API to core and fixes behavior; no public API breaks.
+- Baton is not re-released: its behavior is identical, and the next Baton release will pick up the
+  new dependency bound.
+
+## Impact
+
+- **Functionality**: architecture models, `status --where`, Loom and `analyze` / `verify --claims`
+  no longer read another checkout as the project's code.
+- **Performance**: one `stat` per visited directory. Negligible.
+- **Security / Privacy / Environmental**: N/A.
+
+## Verification
+
+- [x] `cargo test --workspace`: 1041 passed
+- [x] Clippy: core and Baton clean with `-D warnings`; Loom clean; CLI unchanged from the baseline
+      (18/24)
+- [x] Before/after `architecture generate` on the adopter repository, read-only

+## CLI 3.49.2 / core 0.10.1 / Loom 0.7.1 — 2026-09-18
+
+Follow-up to #434, which fixed the Baton half. The shared source scanner in `straymark-core` and two CLI walkers also descended into **another checkout nested in the project**: a linked git worktree such as `.worktrees/<name>/`, a submodule or a nested clone. Each read that copy as the project's own code. On an adopter's repository with one worktree inside, `straymark architecture generate` invented a `.worktrees` component holding a full copy of the repo.
+
+### Fixed (CLI / core / Loom)
+
+- **`straymark-core` 0.10.1**: new `walk::is_nested_checkout`, the one rule every project-wide walker shares. A sub-directory with its own `.git` (file or directory) is another checkout and is never walked. It is structural, so no gitignore parsing and nothing to configure. `architecture::collect_source_files` uses it, which covers:
+  - `straymark architecture generate | sync | validate` and `status --where`;
+  - Loom's architecture view and Intent plane (**Loom 0.7.1**, rebuilt);
+  - Baton's overlay.
+- **CLI 3.49.2**: `tree_grep` (behind `followups verify --claims` and `analyze declared-vs-wired`) and the `analyze` complexity walker use the same rule. A worktree copy no longer counts as "callers" of a symbol, and its functions are no longer analyzed twice.
+- Baton now reuses the `core` rule instead of its own copy. Its behavior is unchanged.
+
+Until upgraded, the workaround is `architecture: { excluded_dirs: [".worktrees"] }` in `.straymark/config.yml`, which covers only the architecture scanner and only that directory name.
+
 ## Baton 0.3.0 — 2026-09-17
 
 First Baton release driven by an adopter's Track C work (Estoa, Discussion #426). Before it, the declared-verb router (#332) classified only units with their own slot: every SpecKit task and every batch was `undeclared`, and the inventory counted work that was not live. Experimental; distributed as `baton-*` GitHub releases (`--latest=false`).

 ## [Unreleased]
 
+## [0.7.1] — 2026-09-18 (nested checkouts)
+
+### Fixed
+- Rebuilt against `straymark-core` 0.10.1, whose source scanner no longer descends into another
+  checkout nested in the project: a linked git worktree (`.worktrees/<name>/`), a submodule or a
+  nested clone (#434). Before, the architecture view's on-disk inventory counted that copy as the
+  project's own code, which inflated `uncharted` files and duplicated whole modules. The Intent
+  plane's overlay uses the same inventory, so it is fixed too. No Loom code change.
+
 ## [0.6.2] — 2026-06-16 (scoped has-debt attribution)
