Why: declarations were passing as capability; hand-transcribed outputs flowed
through cards and PR bodies as if they were execution evidence, and stale
external facts (e.g. the dead git-panel host) kept being trusted until burned.
Evidence: guidelines draft.10 (PR Development-Guidelines#4, merged af199ee)
pinned here; policy/facts.md F1-F4 each re-verified on 2026-10-05 before
registration (endpoint version, token HTTP 200 via header only, SSH ls-remote,
dead-host negative probe); scripts syntax-checked (bash -n); tool self-tests
and make test recorded in the task card via the new make evidence.
Impact: new AGENTS.md section (SELF/REPLAY/GATE, tool-written evidence,
replay-on-review, zero-trust facts, honest-empty); make evidence/facts-verify;
precheck gains [hooks]/[facts], task-sync gains stale-evidence-HEAD warning;
task-start cards now embed the evidence table; gitlink advances to draft.10.
Refs: task card .task/feature-evidence-driven-gates.md; guidelines CHANGELOG
0.1.0-draft.10.
