+# PR 32 CI: restore bao-tree checkout on a legal path
+
+**Date:** 2026-08-13  
+**Workspace:** `/home/hunter/Projects/surmount/carbonado`  
+**HEAD (committed YAML still had the illegal sibling checkout):** `b8c070ae64da98a9a2743dfdb48e8f75322b4f93`
+
+## What changed
+
+The previous working-tree change deleted all six `actions/checkout` steps that fetch bao-tree. That is reversed.
+
+Every job that had **Checkout bao-tree keyed fork (sibling for path dep)** now has the step again. The path is inside `GITHUB_WORKSPACE`. Cargo is pointed at that tree before any cargo/just step.
+
+`git diff HEAD -- .github/workflows/rust.yaml` is a restore-and-rewire (repo/ref/path + a patch step), not a net deletion of the checkout feature.
+
+## In-workspace path
+
+| Field | Old (illegal) | New |
+|-------|---------------|-----|
+| `repository` | `SurmountSystems/bao-tree` | `n0-computer/bao-tree` |
+| `ref` | `76-keyed-bao` | `keyed-bao` |
+| `path` | `../bao-tree` | `bao-tree` |
+
+`path: bao-tree` is `${GITHUB_WORKSPACE}/bao-tree`, i.e. `/home/runner/work/carbonado/carbonado/bao-tree`. `actions/checkout@v4` accepts that.
+
+Product `Cargo.toml` already uses `git = "https://github.com/n0-computer/bao-tree.git"`, `branch = "keyed-bao"`. The checkout matches that source, not the SurmountSystems `76-keyed-bao` sibling used only by local `just setup-bao-tree`.
+
+Local optional path is unchanged: `just setup-bao-tree` / `.cargo/config.toml.example` still talk about `../bao-tree`.
+
+`/bao-tree` is gitignored so an in-workspace clone is not committed.
+
+## How cargo is patched (CI-only)
+
+Committed `.cargo/config.toml` still only has the bitcoinpqc `[patch.crates-io]` block. That file is not overwritten.
+
+Each job, after the bao-tree checkout, runs the composite
+`.github/actions/ci-patch-bao-tree`. That step:
+
+1. Fail-closes unless `${GITHUB_WORKSPACE}/bao-tree/Cargo.toml` exists.
+2. **Appends** (does not replace) this table to `.cargo/config.toml`:
+
+```toml
+[patch."https://github.com/n0-computer/bao-tree.git"]
+bao-tree = { path = "${GITHUB_WORKSPACE}/bao-tree" }
+```
+
+The path is absolute so it does not depend on whether cargo resolves patch paths relative to `.cargo/` or the workspace root. The git URL matches `Cargo.toml` exactly. The bitcoinpqc patch stays in place.
+
+This append is job-local. It is not committed. Developers without a sibling or in-workspace tree keep using the public git dep.
+
+## Jobs covered
+
+Same six jobs as `git show HEAD:.github/workflows/rust.yaml`:
+
+| Job | Checkout restored | Patch before cargo |
+|-----|-------------------|--------------------|
+| `lint` | yes | yes (before `just fmt` / `just lint`) |
+| `lint-wasm` | yes | yes (before `just lint-wasm`) |
+| `desktop` | yes | yes (before `cargo test` / just) |
+| `test-matrix` | yes | yes (before `cargo check`) |
+| `web-check` | yes | yes (before `cargo check`) |
+| `dual-backend-lean` | yes | yes (before nix + `just test-lean-ci`) |
+
+No `--all-features`. Tests were not weakened. No commit or push.
+
+## Process note
+
+This L2 session could not launch a workflow (host: workflows only from a top-level session). Inventory used `git show HEAD:.github/workflows/rust.yaml`, `Cargo.toml`, `.cargo/config.toml`, `.cargo/config.toml.example`, and `justfile`.

+# PR 32 CI diagnosis
+
+**PR:** https://github.com/bitmask-stack/carbonado/pull/32  
+**Branch:** `lean` → `main` (draft, title “proven”)  
+**HEAD:** `b8c070ae64da98a9a2743dfdb48e8f75322b4f93`  
+**Date observed:** 2026-08-13
+
+## What ran
+
+Workflows are not skipped, pending forever, or missing. One workflow exists (`Rust` / `.github/workflows/rust.yaml`). Both the `push` run ([101](https://github.com/bitmask-stack/carbonado/actions/runs/31745640857)) and the `pull_request` run ([102](https://github.com/bitmask-stack/carbonado/actions/runs/31745690786)) completed in about ten seconds as **failure**. Combined commit status is `pending` with **zero** commit statuses. That is normal: this repo uses Actions check runs, not the old status API.
+
+| Check name | Conclusion | Why |
+|------------|------------|-----|
+| `lint` | **failure** | Illegal sibling checkout (below) |
+| `lint-wasm` | **failure** | Same |
+| `desktop` | skipped | `needs: lint` |
+| `test-matrix` | skipped | `needs: lint` |
+| `dual-backend-lean` | skipped | `needs: lint` |
+| `web-check` | skipped | `needs: lint-wasm` |
+
+Job names match `docs/TEST_CONTRACT.md` (`desktop`, `dual-backend-lean`, plus lint/matrix). This is not a branch-protection name mismatch. There are no PR comments about CI. Rustc, clippy, and tests never started.
+
+## Root cause
+
+Every job checked out `SurmountSystems/bao-tree` at `76-keyed-bao` with `path: ../bao-tree`. `actions/checkout@v4` refuses any path outside `GITHUB_WORKSPACE`.
+
+Quoted from `lint` / `lint-wasm` on run 102:
+
+```
+Repository path '/home/runner/work/carbonado/bao-tree' is not under '/home/runner/work/carbonado/carbonado'
+```
+
+Failed step: **Checkout bao-tree keyed fork (sibling for path dep)**.
+
+That step is leftover from an optional local path patch (`just dev-local-bao` / `.cargo/config.toml.example`). CI does not copy that example. Product `Cargo.toml` already uses a public git dep:
+
+`git+https://github.com/n0-computer/bao-tree.git?branch=keyed-bao` (lock pin `e82e744…`; branch is public).
+
+Committed `.cargo/config.toml` only patches `bitcoinpqc` to a public git rev. It does **not** force `../bao-tree`. So CI does not need a sibling checkout.
+
+Local `just check` looks fine because it never runs `actions/checkout`. Same illegal step already fails `main` the same way (run 99, 2026-07-09).
+
+Not the cause: YAML syntax, path filters, permissions, n0-computer fetch (never reached), dual-backend `--all-features` (PR already avoids that).
+
+## Fix applied (not committed, not pushed)
+
+Removed all six sibling `actions/checkout` steps from [`.github/workflows/rust.yaml`](../../.github/workflows/rust.yaml) and left a short comment. Cargo on CI will fetch `n0-computer/bao-tree` `keyed-bao` as `Cargo.toml` already says.
+
+After this file is on `lean`, re-run the PR workflow. Later jobs may still fail on real compile/test; this change only unblocks the first step.
+
+## Residual (not this outage)
+
+- `keyed-bao` is a moving branch; `/Cargo.lock` is gitignored, so CI is not pinned to a lockfile.
+- `just setup-bao-tree` still clones `SurmountSystems` `76-keyed-bao`. Local optional path patch vs product git source can drift. Separate from this CI break.
