Contributor guidance contradicted itself in four places (found in the #8084 review):
- pull_request_template.md + CONTRIBUTING.md asked contributors to run the FULL
unit suite + coverage gate locally, while the maintainer's stated golden path
(#8273/#8329) is: focused tests for the change locally; full suite, coverage,
and build are CI's job. On 16GB hosts the full local chain has saturated
machines (#8084 incident report).
- GEMINI.md demanded coverage >= 75/75/75/70 while the official CI gate is
60/60/60/60 (quality-baseline ratchet on top).
- AGENTS.md fork workflow said to branch from upstream/main; the default branch
is the active release/vX.Y.Z line (main only receives release squash-merges).
Also makes the #8084 CI direction explicit in the public ROADMAP: lane
consolidation (3.8.51), one CI policy for release/** and main (3.8.52),
full-regression authority -> merge queue after TIA shadow evidence (3.8.54),
preview-artifact + build-once rehearsal inside the 3.8.58 dry-run.
