Bone Flow #002 Bone Joint Rebuild Package 1.0.19
Runtime: BoneJoint 1.1.37
Status: Development Candidate - user localhost confirmation required

Scope of this patch:
- Align destination direction-triangle tip to the actual Target endpoint.
- Remove the black outline from the destination direction triangle.
- Restore/add semantic HTML Functional Class modifiers: bf-joint-in / bf-joint-out on the existing bf-joint adapter.
- Preserve existing bf-joint Runtime delegation, WAIT/FIFO/BLOCKED, routes, diagnostics, cumulative regression links, and test UI.
- No #021 Bone Shape files are included or modified.

Validation performed in build environment:
- JavaScript syntax: PASS (all source JS + rebuilt boneflow.js + inline test scripts).
- Runtime browser harness (headless Chromium, in-memory page): PASS.
  - bf-joint-in -> host/path role = in.
  - bf-joint-out -> host/path role = out.
  - direction triangle first point = resolved Target endpoint.
  - direction triangle stroke = none / stroke-width = 0.
- Full #002 test page executed in headless Chromium with package JS/CSS inlined:
  - Smoke + Validation: ALL PASS, 173 / 173, FAIL 0.
  - Page errors: 0.
  - Console warning/error: 0.
- Regression structure:
  - package file count unchanged: 57 before / 57 after prior to final manifest regeneration.
  - bone-joint.html id count unchanged: 106 total / 100 unique.
  - existing duplicate IDs unchanged: type-error, type-warning.
  - Smoke registrations: 71 -> 73 (2 targeted checks added).
  - Validation registrations: 102 -> 103 (1 targeted check added).
  - bone-development-order.html structure unchanged: ids 7, sections 4, links 2.

Important:
- Direct navigation to a localhost/file URL from the build-environment Chromium is administratively blocked, so user localhost visual confirmation is NOT claimed.
- User confirmation at the formal localhost URL is still required before Completed / Specification Frozen.
