Symptom: microflow describe emitted explicit @anchor fragments for flows that used the MDL default connection sides, creating cosmetic drift in round-trip output. Root cause: anchor formatting printed every known from/to side even when the value matched the statement default: regular flows use right-to-left, true branches use right-to-left, and false branches use bottom-to-top. Fix: omit default anchor fragments and skip the annotation entirely when all sides are defaults, while preserving explicit non-default sides. Tests: added regression coverage for omitted regular and split defaults, and adjusted existing split-anchor tests to assert that non-default branch anchors are still emitted.

RecommendationApprove the PR. The fix is correct, well-tested, and maintains backward compatibility for non-default cases while improving roundtrip fidelity by omitting semantically redundant default values. No changes requested.

Adds an MDL script under mdl-examples/bug-tests/ verifying that linear flows produce zero @anchor lines (all defaults) while non-default sides like `to: top` survive a describe → exec → describe cycle. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
AI Code ReviewCritical IssuesNone found. Moderate IssuesNone found. Minor IssuesNone found. What Looks Good
RecommendationApprove. The PR correctly fixes issue #320 by suppressing redundant default anchor fragments in DESCRIBE MICROFLOW output while preserving non-default annotations. The changes are minimal, well-tested, and maintain backward compatibility for cases where non-default anchors exist. All checklist items are satisfied for this bug fix.

Part of #332.
Fixes #320.
Summary
DESCRIBE MICROFLOWnow omits anchor fragments when all emitted sides match the MDL defaults.Root cause
Anchor formatting printed every known
from/toside even when the side matched the statement default. These explicit defaults were semantically redundant and created cosmetic roundtrip drift.Fix
Suppress default fragments for regular flows and split branches. Non-default sides are still emitted.
This intentionally changes describe output for flows that only used default sides.
Tests
Added regression coverage for omitted defaults and non-default anchor preservation.
