I2761 — A branch that renumbered its decision away claims nothing at the old number

Cíl

Count a ref as claiming an ADR identity only while its tip carries the document, so that renumbering one of two colliding decisions clears the collision for the other branch.

Proč

On 2026-10-16 two sessions took ADR 0168 within minutes: #947 (the d8 mesh segment) and #1293 (I1101). The landing seat decided that #947 keeps 0168, and #1293 renamed its decision to 0169 and pushed. #947's commit was still refused by the pre-commit hook with `identity 0168 is also claimed by .ai/repo/adrs/0168-what-an-adoption-leaves-behind-is-measured-not-remembered.md, on: docs/adoption-footprint-forensics`. mj_adr_collisions asks which refs contain the commit that once added the path, and #1293's branch still contains that commit in its history. No branch carried the document any more, and the only way past was --no-verify, which this repository forbids.

Aktuální stav

mj_adr_collisions reports a collision for every path that any ref's history ever added, for as long as any ref contains that add-commit, whether or not the document still exists at the ref's tip.

Cílový stav

A ref claims an identity while `git cat-file -e <ref>:<path>` holds. A path that no current tip carries is no collision, whereas one in an unreferenced commit is still reported as before. The allocator (`adr next`) is unchanged: a withdrawn identity stays spent there.
