fix(routing): W6 ronde — 6 findings closed (README bootstrap path, 2 census gaps, 3 stale refs)

Fresh-opus whole-chantier ronde (17fbe51..HEAD, EVAL-023 style): axes
severed-wires / gate-regressions / fail-open PROVEN CLEAN (all 7 new
handoffs traced end-to-end both sides). Fixed: init 5b now dispatches the
FULL-AUDIT path (auto-mode gated a missing README as SIGNIFICANT →
[CREATE-AUTO] unconditional restored, sole greenfield README path);
census locks added for /geo ERROR CONTRACT + never-re-derive (deleting
the fail-closed handler would have stayed green), doc-audit
model=opus override x5 flows, SYNTH REPORT grammar; doc-syncer ex-STEP-8
prose repointed to the dispatcher gate; plugin-advisor anim rows read
the PROBE REPORT ANIM field (no Bash anymore); client-handover 9.7
cleans the transient draft. Census caught one more line-wrapped lock
before it shipped vacuous. 133 pass / 0 fail, make test exit 0.
