 ## Status
 
-- Status: active
-- Current phase: 5. Implement owned slices
-- Next safe action: write the focused regression test against Pi 0.84.4, confirm it fails, then upgrade the aligned Pi packages to 0.85.0.
+- 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 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.
+- 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.

 ## 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.
+- [ ] `@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 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: (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: approved by the user through `ask_user` on 04SEP2026 (`approve_085`).
+- 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 user approved the aligned Pi 0.85.0 repository dependency upgrade. The user selected repository-only scope, so the active global Pi 0.84.4 installation remains unchanged.
+- 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.
