Bash worktree cwd workflow record

Status

Status: waiting
Current phase: 3. Design and obtain plan approval
Next safe action: present the revised local-override plan and obtain explicit approval before further product mutation.

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; add a repository-owned, publishable @jbcode/pi-bash-cwd extension that delegates to Pi's built-in Bash implementation using each call's ctx.cwd; test workspace-root, nested-package, and missing-directory execution in a disposable hidden worktree; update package inventory and documentation; remove the resolved TODO.
Out of scope: upgrading Pi, changing Bash's public per-call arguments, installing or publishing the new package, deploying, pushing, or modifying live/production data.

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.

@jbcode/pi-bash-cwd overrides the built-in bash tool without changing its public arguments, output, truncation, cancellation, timeout, session-environment, or renderer contracts.
The override constructs the delegated built-in tool with the current execution ctx.cwd, rather than the extension factory's 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.
Package inventory, README guidance, and the upstream Pi 0.85.0 packaging blocker TODO are synchronized.
Existing repository typecheck and test suites pass.
The resolved Bash cwd TODO and temporary workaround language are removed or updated without changing unrelated historical evidence.

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 revised approval. Proposed: (1) create extensions/bash-cwd as a publishable @jbcode/pi-bash-cwd package; (2) override bash by preserving the host's built-in schema, metadata, rendering, and execution behavior while constructing the delegated built-in tool from the live ctx.cwd; (3) move the red regression into the package and cover hidden-worktree root, nested package, and fail-before-sentinel cases; (4) add the package to workspace/package checks and root test execution; (5) document installation and compatibility, remove the resolved Bash cwd TODO, annotate historical workaround text, and add a separate TODO for removing the local override after a usable upstream release; (6) run focused package tests, packaging checks, typecheck, and the full repository suite.
Plan approval: pending after the Pi 0.85.0 blocker forced replanning. The user selected local_override and then publishable_package through ask_user on 04SEP2026.
UI classification and direction approval: non-UI; no prototype gate applies.
Risk decisions and scope: the approved Pi dependency upgrade was abandoned and fully restored after Pi 0.85.0 failed to load. No new dependency will be added. The new package remains repository-only and will not be installed, published, or added to the active global Pi environment in this task.

Findings and remediation cycles: Pi 0.85.0 includes the upstream ctx.cwd correction but its public package imports undeclared @earendil-works/pi-server, causing ERR_MODULE_NOT_FOUND. The user rejected adding that dependency and selected a repository-owned override. The attempted catalog/lock upgrade was restored; a focused red test remains as inspected uncommitted work pending replan approval.
Before/after reviewer Git evidence: pending

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.

Last committed valid checkpoint: initial record commit 5f853dc
Blockers: revised exact-plan approval.
Exact next safe action: present this revised record and ask the user to approve or reject the local-override implementation plan.
