Isolation-safe way to move an already-populated submodule to HEAD's recorded gitlink after a pin bump. Refuses dirty or ahead-of-pin checkouts; never uses git submodule update. Documented and hermetic- tested. Fixes #2233 Co-authored-by: Nikolai Emil Damm <devantler@users.noreply.github.com>
Keep AGENTS.md in sync with the new --advance mode so agents do not reach for plain git submodule update after a pin bump. Part of #2233 Co-authored-by: Nikolai Emil Damm <devantler@users.noreply.github.com>
Co-authored-by: ned <ned@devantler.tech>
Keep --advance plus its tests, while adopting main's scoped probe cleanup, same_dir identity checks, and source-guard for unit tests. Co-authored-by: ned <ned@devantler.tech>
Keep main's #2492 empty-init fail-closed coverage as case 11 and renumber --advance cases to 12–14. Co-authored-by: ned <ned@devantler.tech>
Incomplete $cN renumber left mk_super on the previous case's path, so cases 13–14 rebuilt the wrong fixture and aborted under set -e. Co-authored-by: ned <ned@devantler.tech>

- Around line 301-344: Move repair "$path" and its probe "$path" validation
immediately after the is_populated check in the advance flow, before any git -C
"$path" status, rev-parse, fetch, or checkout operations. Preserve the existing

first assert that `$new_sha` is absent from the submodule’s object database,

During code review, treat `.claude/**/*.md` as needing the same markdownlint-clean style as the docs—e.g., avoid MD022 issues like missing/incorrect blank lines around headings—and flag markdownlint violations even though CI won’t catch them.

Learning: For prose “subagent definition” documents under `.claude/agents/**` (e.g., `portfolio-surveyor.md`) that are interpreted by an LLM rather than executed deterministically: in CI, use focused textual contract assertions (e.g., checking required sections, prompts, and structural constraints). Do not attempt behavioral validation by simulating it via non-deterministic model invocations; behavioral validation should require live Surveyor runs.
For executable components under `.claude/scripts/**` (e.g., `release-bot-exemption.sh`): use fixture-driven, deterministic tests that exercise the script logic with controlled inputs/outputs (rather than model calls).

Learning: In `.claude/scripts` test fixture scripts, when running Git setup commands (e.g., `git worktree add`, `git submodule add`), do not suppress failures (e.g., by ignoring exit codes or redirecting errors to `/dev/null`) without explicitly checking command status. A setup failure can otherwise cause contract tests to falsely pass (for example, due to empty/incorrect Git porcelain output). Preserve stderr for diagnostics and fail the fixture immediately if setup steps return a non-zero exit code (use `set -e`/`set -o pipefail` and/or explicit `if ! command; then ...; exit 1; fi`).

Learning: In shell test harness/ablation scripts, capture the exit status of the command being tested immediately into `rc=$?` on the very next line. Avoid using `$?` as an argument to another command (e.g., `printf ... "$?"` or similar) when the same line also includes `$(...)` command substitution, because shell evaluation/expansion order can replace the tested command’s exit status with the exit status of the command substitution, producing incorrect measurements.

Repair isolation before Git uses the populated checkout.
Lines 304-341 run git -C "$path" before repair "$path". If a stale shared core.worktree already redirects this submodule, git checkout --detach "$target" can update another session’s worktree before this command repairs the configuration.
Run repair and probe immediately after the populated-checkout check. Do this before status, rev-parse, or checkout. Add a fixture with a pre-existing stale core.worktree and verify that --advance does not modify the redirected worktree.

Exercise the script-side target fetch.
Lines 396-397 make $new_sha available before --advance runs. This makes cat-file succeed and bypasses the target-fetch path in submodule-init.sh.
Remove the fixture-side fetch. Assert that the target object is initially absent, then verify that --advance fetches and checks out the recorded pin. The PR objective requires this workflow to be empirically verified. Based on learnings, executable components under .claude/scripts/** must use fixture-driven, deterministic tests that exercise script logic with controlled inputs and outputs.

Why
Once a submodule is already populated, advancing it to a new committed pin had no verified one-command path — agents either skipped the bump or risked breaking worktree isolation.
What
Adds a tested
--advancemode to the submodule init helper so a populated checkout can move to the recorded pin safely, and documents that as the supported path.Fixes #2233
