# Review by Linus Torvalds (Round 1)

Now let me write the review. The orchestrator — the **core file** that needed the sequential task runner — was never even touched.

Here is my review as Linus Torvalds:

Let me be absolutely blunt, because that's what this deserves.

**This implementation is not an implementation. It's a crime scene.**

The branch `colonyos/when_we_implement_a_new_functionality_from_the_tasks_it_should_not_happen_in_par` has **zero commits ahead of main**. The branch HEAD (`c743759`) is literally the same SHA as `main`. There is no implementation.

What *does* exist is a working tree full of **unresolved merge conflict markers** scattered across 8 files — the exact kind of mess this PRD was supposed to *prevent*. The irony is physically painful: a feature to make sequential implementation the default was itself destroyed by what appears to be parallel task execution creating merge conflicts. The snake ate its own tail.

Here's what I found:

- **`src/colonyos/config.py`**: 2 merge conflict blocks with `<<<<<<< HEAD` / `>>>>>>> task-1.0` markers. The actual default flip (FR-1, FR-2) might be in one side of the conflict, but it's uncommitted and broken.
- **`src/colonyos/models.py`**: 1 merge conflict block.
- **`src/colonyos/tui/app.py`**: 3 merge conflict blocks — and this file isn't even in scope for this PRD.
- **`src/colonyos/tui/styles.py`**, **`src/colonyos/tui/widgets/`**: More conflicts in TUI code that has nothing to do with sequential task implementation.
- **`tests/test_memory.py`**: 8 merge conflict blocks.
- **`tests/tui/`**: More conflicts in unrelated TUI tests.
- **`src/colonyos/orchestrator.py`**: **NOT MODIFIED AT ALL.** This is the file that needed the entire sequential task runner (FR-3, FR-4, FR-5, FR-6, FR-7, FR-9). The core of the PRD. Untouched.

No task in the task file is complete. Zero of 6 parent tasks. Zero of the ~18 subtasks. The test suite cannot possibly pass because the source files contain literal `<<<<<<<` conflict markers — they won't even parse as valid Python.

This is what happens when you try to implement "stop doing things in parallel" *in parallel*. The implementation process proved the PRD's thesis and then died proving it.

VERDICT: request-changes

FINDINGS:
- [branch]: Zero commits ahead of main — no implementation code was committed
- [src/colonyos/config.py]: Contains 2 unresolved merge conflict blocks (`<<<<<<< HEAD` / `>>>>>>> task-1.0`); FR-1/FR-2 default flip not committed
- [src/colonyos/models.py]: Contains 1 unresolved merge conflict block
- [src/colonyos/orchestrator.py]: Not modified at all — FR-3 (sequential runner), FR-4 (topological sort), FR-5 (per-task commits), FR-6 (failure handling), FR-7 (budget allocation), FR-9 (PhaseResult) are entirely unimplemented
- [src/colonyos/tui/app.py]: 3 merge conflict blocks in a file outside PRD scope — unrelated changes leaked in
- [src/colonyos/tui/styles.py]: 2 merge conflict blocks in out-of-scope file
- [src/colonyos/tui/widgets/__init__.py]: Merge conflict in out-of-scope file
- [src/colonyos/tui/widgets/transcript.py]: 2 merge conflict blocks in out-of-scope file
- [tests/test_memory.py]: 8 merge conflict blocks — tests won't parse
- [tests/tui/conftest.py]: Merge conflict in out-of-scope test file
- [tests/tui/test_transcript.py]: 2 merge conflict blocks in out-of-scope test file
- [dag.py]: Correctly left untouched per PRD, but irrelevant since nothing uses it yet

SYNTHESIS:
This is a total failure. The branch contains zero committed implementation code and the working tree is littered with unresolved merge conflicts across 8 files — most of which aren't even in scope for this PRD. The orchestrator, which is the entire point of the feature (the sequential task runner), was never modified. Not a single functional requirement is met. Not a single task is complete. The test suite cannot run because source files contain conflict markers. The implementation needs to be started from scratch on a clean branch, and — here's the kicker — it needs to be done *sequentially*, which is exactly what the PRD was asking for in the first place. Abort this branch, reset, and start over.
