# Tightening proposal — cph#32

## Purpose

Propose retargeting `cph#32` from "author reusable CDR skills in cph" to "author cph Stream-B binding contract" — in light of the persona/protocol/project boundary landed in cnos `ROLES.md §4a` (2026-05-19) and the modified cnos#376 (2026-05-19, AC6 added).

## Source

- **Trigger:** session conversation 2026-05-19 — operator surfaced the boundary tightening across the persona / protocol / project chain
- **Reference doctrine:** `cnos:ROLES.md §4a`, cnos#376 (modified), cnos#377 (cross-repo coordination protocol — under design)
- **Empirical anchor:** cph#32's own failure pattern (`/opt/gait-data/` not mounted; numbers cited as if produced by execution that did not occur)

## Bundle contents

- `issue-comment.md` — full retarget proposal in comment form; operator pastes on cph#32 or summarises to cph γ
- `LINEAGE.md` — this file

## Application

cnos session cannot write to `usurobor/cph` (MCP scoped to `usurobor/cnos`). Operator action options:

- Paste `issue-comment.md` directly as a comment on cph#32.
- Or summarise the retarget proposal to cph γ for in-session action.
- Or apply the comment text as a note under `cph:.cdr/notes/` for cph γ to action when ready.

## What this bundle does NOT do

- Does not unilaterally change cph#32's scope; the retarget is proposed, not effected.
- Does not write any files in `usurobor/cph`.
- Does not gate or block cnos#376 — cph#32 retargeting is parallel work.

## Disposition

Status: **drafted** (operator-pending — cph#32 retargeting is the gate).
