FN-5928: enforce surface enumeration for bug-fix invariants
Require bug-fix specs and reviews to enumerate affected surfaces and reject repro-only regression coverage. - add a required `## Surface Enumeration` section to triage prompt templates and bug-fix planning guidance - tighten reviewer guidance to block missing surface enumeration and repro-only regression tests - document the canonical surface checklist in `docs/testing.md` and cover the new wording with prompt/reviewer tests Files changed: AGENTS.md | 6 ++-- docs/testing.md | 9 +++++ packages/core/src/__tests__/agent-prompts.test.ts | 22 ++++++++++++ packages/core/src/agent-prompts.ts | 16 +++++++++ packages/engine/src/__tests__/reviewer.test.ts | 17 ++++++++++ packages/engine/src/__tests__/triage.test.ts | 41 ++++++++++++++++++++--- packages/engine/src/reviewer.ts | 3 ++ packages/engine/src/triage.ts | 24 +++++++++++++ 8 files changed, 131 insertions(+), 7 deletions(-) Fusion-Task-Id: FN-5928 Fusion-Task-Lineage: 717ddcbe-f3a6-4589-ad90-4e640f7a9ff2

Flag REVISE when key edge cases or failure modes for changed behavior are untested.

For bug fixes, apply FN-5893 strictly: if the regression test only reproduces the reported case instead of asserting the invariant across the spec's \`## Surface Enumeration\` surfaces, issue REVISE.
