r2 M-r2-1: AC6 now mirrors AC5's structure with two explicit cases — a
candidate-side TypeError is an honest WS error, a previous-side TypeError
falls back to "no baseline" and the unrelated write passes. An
implementation with swapped or missing asymmetry turns at least one of the
two units red. L2: the risk wording follows §2.3's component-sum phrasing.

r1-H1: node keys quantise with the repository's canonicalisation formula
(sign·floor(|v|·1e7+0.5)/1e7) — native Math.round and Python round() part
ways on .5 ticks, the exact parity lesson coordinate-canonicalization
already encodes. r1-M1: the incidence threshold becomes 2e-7 over raw
coordinates, which the spec's own example (1.02e-7) actually satisfies; the
known valence undercount on neighbouring quanta is stated in §3. r1-M2: the
narrow except applies to the candidate side only — a previous-side migration
bug stays a "no baseline" fallback, symmetric with §2.5. r1-M3: the branch
walk is an O(E) edge traversal of the collinear component, not a
combinatorial DFS; AC3 gains a 100-fork case. r1-M4: the USER-GUIDE limits
section documents the new refusal toast. L1: §1 opens with the user
sentence.

Quantised node keys with -0 normalisation and node incidence at the quantum,
zero-degree wedges become visible, an iterative maximal-branch wall run, arc
collinearity measured against the chain base, fail-closed candidate checks,
and a narrow except in the python mirror. Every reproduction in §1 was
verified by execution on current dev after #330.
