Closes Plan 01-11 honestly per GSD spike-pivot pattern. Original
Approach A (Puppeteer sw.evaluate per RESEARCH §1+6) empirically
falsified across Wave 3 execution + feasibility research. Approach B
(extension-internal-page harness + offscreen synthetic stream) proven
via c647f61 prototype; full implementation moves to Plan 01-13.
What this commit does:
- ADDS 01-11-SUMMARY.md (spike-then-pivot framing per GSD artifact-
types.md PLAN→SUMMARY lifecycle; captures retained infrastructure,
falsified hypotheses, working prototype, bridge to 01-13)
- REVERTS frontmatter amendment block in 01-11-PLAN.md; replaces with
closed_as/pivoted_in/closure_note pointing at SUMMARY + 01-13
- DELETES 01-11-PLAN-AMENDMENT-A.md (improvised artifact type — not
recognized in GSD artifact-types.md; content folded into SUMMARY)
Lesson for orchestrator (captured in SUMMARY §Architectural Notes):
when a plan attempts an approach that proves infeasible, the right
move is honest SUMMARY + new plan, NOT in-place rewrite + AMENDMENT
artifact. The project's own pattern (01-08, 01-09, 01-10, 01-11
added mid-phase as new work surfaced) confirms add-new-plan-when-
scope-shifts is the established pattern.
Plan 01-09 closure via harness PASS NOT achieved by 01-11; still
requires operator UAT pending Plan 01-13 landing.
