# Bash worktree cwd workflow record
## Status
- Status: waiting
- Current phase: 2. Discover and decide requirements
- Next safe action: obtain approval for the Pi dependency upgrade scope and implementation plan before changing dependencies.
## Request and scope
- Request: address the first repository TODO so Bash execution honors the current Pi tool context inside hidden Git worktrees.
- In scope: reproduce the Pi 0.84.4 behavior, adopt the upstream Pi 0.85.0 cwd correction through the repository dependency set, test workspace-root and nested-package execution in a disposable hidden worktree, update affected documentation, and remove the resolved TODO.
- Out of scope: adding a custom Bash override, changing Bash's public per-call arguments, publishing packages, deploying, pushing, or modifying live/production data.
## Git identity
- Source branch: `main`
- Base commit: `7e7cfdb5cb0e1a1218b9a2c8250267d5099637fc`
- Feature branch: `feature/honor-bash-worktree-cwd`
- Worktree: `/srv/data/code/jb-pi/harness-tools/.worktrees/honor-bash-worktree-cwd`
- Omitted source changes: none; source checkout was clean and equal to `origin/main` after `git fetch origin main`.
## Acceptance criteria
- [ ] The repository resolves a Pi Coding Agent version whose built-in Bash tool uses the execution `ctx.cwd` instead of the tool factory's original process directory.
- [ ] A regression test executes `pwd` from both a disposable hidden worktree root and a nested workspace package directory and observes the requested directory.
- [ ] A missing requested working directory fails before the shell command can create a sentinel side effect.
- [ ] Existing repository typecheck and test suites pass.
- [ ] The resolved TODO and temporary workaround language are removed or updated without changing unrelated historical evidence.
## Approved implementation plan and gates
- Plan/specification source: user request, `docs/todos.md`, and upstream Pi 0.84.4/0.85.0 source under `/srv/data/opensrc/repos/github.com/earendil-works/pi/`.
- Exact plan: pending approval. Proposed: (1) add a focused repository regression harness for dynamic Bash `ctx.cwd` with hidden-worktree root, nested package, and missing-directory cases; (2) update the aligned `@earendil-works/pi-ai`, `@earendil-works/pi-coding-agent`, and `@earendil-works/pi-tui` catalog versions to 0.85.0 and regenerate `bun.lock`; (3) run focused tests, typecheck, and the full suite; (4) update README compatibility text and resolve the TODO/workaround references; (5) verify in a fresh Pi 0.85.0 process without changing the currently running global Pi installation.
- Plan approval: pending.
- UI classification and direction approval: non-UI; no prototype gate applies.
- Risk decisions and scope: dependency upgrade requires explicit approval. Global Pi installation changes are excluded unless separately authorized.
## Ownership
| Assignment | Owner identity | Deadline | Exclusive paths | Before/after Git evidence | Outcome |
| --- | --- | --- | --- | --- | --- |
| Workflow setup and research | parent Pi session `01a06e08-8d07-76a7-a116-d7e3baf55b87` | 15 minutes | workflow record only | Before: clean `main` at `7e7cfdb`; after: pending initial record commit | In progress |
## Verification matrix
| Surface | Command | Exit code | Outcome |
| --- | --- | --- | --- |
| Source/cache preflight | `git status --short --branch`; `opensrc path ...` | 0 | Clean source; Pi 0.84.4 and 0.85.0 source available locally. |
| Focused cwd regression | pending | pending | pending |
| Typecheck | `bun run typecheck` | pending | pending |
| Full tests | `bun run test` | pending | pending |
| Fresh-process integration | pending | pending | pending |
## Review
- Base and product HEAD: pending
- Clean status and tree hash: pending
- Commit list: pending
- Exact diff command: pending
- SHA-256: pending
- Mutator identities: parent Pi session `01a06e08-8d07-76a7-a116-d7e3baf55b87`
- Standards reviewer identity, digest confirmation, and verdict: pending
- Specification reviewer identity, digest confirmation, and verdict: pending
- Findings and remediation cycles: none yet
- Before/after reviewer Git evidence: pending
## Integration and rollback
- Synchronization and re-verification: fetch/rebase onto latest `origin/main`, then rerun affected and full verification if the effective tree changes.
- Fast-forward result: pending
- Product and closure commits: pending
- Reachability and cleanup: pending
- Rollback strategy: before integration, delete only the isolated feature branch/worktree after proof and approval if abandoned; after integration, revert the focused dependency/test/docs product commit.
## Checkpoints and blockers
- Last committed valid checkpoint: none yet
- Blockers: dependency-upgrade and exact-plan approval.
- Exact next safe action: commit this initial record, present it, and ask the user to approve or reject the proposed dependency scope and plan.
