TODO Tracking System

Spec TODOs live in docs/spec/todos/ as individual markdown files with YAML frontmatter.

Finding TODOs

• Index: docs/spec/todos/index.md — Single table sorted by ID with status, priority, and dates
• Individual files: docs/spec/todos/TODO-NNNN.md (zero-padded to 4 digits)
• Quick lookup: glob docs/spec/todos/TODO-*.md

Creating a New TODO

1. Derive next ID: Find the highest existing ID and add 1 (do NOT fill gaps — IDs are never reused)
2. Create file using this template:

---
id: <next_id>
title: <short title>
status: todo              # todo | in-progress | done
priority: high            # high | medium | low
created: <YYYY-MM-DD>
depends_on: []            # list of TODO IDs that must complete first
blocks: []                # list of TODO IDs this blocks
---

# TODO-NNNN: <Title>

## Summary
<1-3 sentences describing the goal>

## Details
<Full description: steps, design questions, files to create/update>

3. Update index.md: Add row to the table (sorted by ID)

Updating Status

Starting work (todo → in-progress)

• Update frontmatter: status: in-progress
• Update index.md if needed

Completing (in-progress → done)

1. Update frontmatter:
   yamlCopy

   status: done
   completed: <YYYY-MM-DD>
   files_created: [...]    # files created during resolution
   files_updated: [...]    # files modified during resolution
   

2. Replace ## Details with ## Resolution containing the resolution notes
3. Update index.md: change status, add completed date

Subsumption (absorbed by another TODO)

When a TODO is fully covered by another TODO's implementation:

1. On the subsumed TODO:
   yamlCopy

   status: done
   completed: <date of subsuming TODO's completion>
   subsumed_by: <subsuming TODO ID>
   

2. Rename ## Details to ## Original Scope, add:
   markdownCopy

   ## Resolution
   Subsumed by [TODO-NNNN](TODO-NNNN.md). <brief explanation>.
   

3. On the subsuming TODO, add:
   yamlCopy

   subsumed:
     - <absorbed TODO ID>
   

Dependency Conventions

• depends_on: [8] means "cannot start until #8 is done"
• blocks: [9] means "#9 cannot start until this is done"
• Keep both sides consistent (if A blocks B, then B depends_on A)

File Impact Conventions

Only populated on completion:

• files_created: New files created as part of the resolution
• files_updated: Existing files modified as part of the resolution
• Use spec-relative paths (e.g., commands/check.md, workflows/inference.md)

Relative Links

TODO files live at docs/spec/todos/. Adjust relative links accordingly:

• To spec files: ../terminology.md, ../storage.md, ../commands/check.md, ../workflows/inference.md
• To other TODOs: TODO-NNNN.md (same directory)
