Where the model routing rationale actually lives
Branch fix/doctor-model-routing-link, 2026-09-03. One section of the doctor skill's agents-validation reference pointed at a file deleted in #1302. Docs only, no gate or hook changes.
1. Before and after
Why repoint, not restore. The deleted file was a 114-line prose table that rotted once per model launch. Since #3872 the assignment is machine-readable in each agent's frontmatter and the rationale is a Lab page with the before/after per agent. A second prose copy would only drift again.
2. The live per-agent assignment (as of this branch)
| model: | agents | meaning |
|---|---|---|
sonnet | 23 | discovery and synthesis |
opus | 6 | judges and reviewers |
inherit | 4 | follows the session model, gated by fable-spend-consent |
haiku | 3 | mechanical fan-out |
Reproduce: grep -h '^model:' src/agents/*.md | sort | uniq -c. The counts above were read on 2026-09-03 and will move; the command is the source, this table is a snapshot.
