Investigate Evidence Kit over-budget rows

Objective: Investigate the active Evidence Kit over-budget rows, trace their artifact and registered command, refresh the owning Slate v2 benchmark, fix the control-plane rerun command if needed, regenerate Evidence Kit outputs, and verify the over-budget next action is either still actionable with an owner or removed with evidence.

Goal plan: docs/plans/2026-05-28-investigate-evidence-kit-over-budget-rows.md

Template: docs/plans/templates/task.md

Primary template: docs/plans/templates/task.md

Applied packs:

• none

Task source:

• type: user request
• id / link: current Codex thread
• title: Investigate Evidence Kit over-budget rows
• acceptance criteria: exact over-budget rows identified, source artifact and threshold traced, current benchmark rerun performed from .tmp/slate-v2, control-plane registry corrected when needed, Evidence Kit health/docs refreshed, and goal plan check passes.

Completion threshold:

• benchmark-health-latest.json no longer contains an unexplained investigate-over-budget next action.
• The clipboard artifact has current issue-target thresholds recorded.
• research/benchmark-registry.json contains the reproducible issue-shaped clipboard command.
• benchmarks/editor/iterations/004-clipboard-over-budget-investigation.md records the finding and commands.
• npm run evidence:refresh, npm run docs:perf:check, registry JSON parse, served index.html smoke, and node .agents/rules/autogoal/scripts/check-complete.mjs docs/plans/2026-05-28-investigate-evidence-kit-over-budget-rows.md passes.

Verification surface:

• SLATE_CLIPBOARD_BENCH_HUGE_CUT_BLOCKS=50000 SLATE_CLIPBOARD_BENCH_ISSUE_TARGETS=1 bun run bench:core:clipboard-large-payload:local from /Users/zbeyens/git/plate-2/.tmp/slate-v2
• npm run evidence:refresh from /Users/zbeyens/git/plate-2/benchmarks/editor
• npm run docs:perf:check from /Users/zbeyens/git/plate-2/benchmarks/editor
• node -e "JSON.parse(...benchmark-registry.json...)"
• pnpm exec biome check benchmarks/editor/research/benchmark-registry.json --fix
• served http://127.0.0.1:8765/index.html smoke via Node fetch

Constraints:

• Preserve existing user-facing behavior outside the task scope.
• Prefer the durable ownership boundary over caller-by-caller patches.
• Do not create PRs, comments, commits, or pushes unless the task/user/skill requires them.
• Do not add broad ceremony when the task is trivial or docs-only.

Boundaries:

• Source of truth: active benchmark registry, latest health/result JSON, and the Slate v2 clipboard benchmark artifact.
• Allowed edit scope: benchmarks/editor/research/benchmark-registry.json, benchmarks/editor/iterations/**, generated benchmark/docs outputs, Slate v2 benchmark artifact under .tmp/slate-v2/tmp, and this plan.
• Browser surface: generated static perf index only.
• Tracker sync: N/A, no issue tracker target.
• Non-goals: no Slate v2 runtime optimization, no non-Slate adapter work, no PR.

Blocked condition: Blocked only if the Slate v2 clipboard benchmark command cannot run or the health report still reports over-budget rows after a fresh issue-shaped rerun without enough source data to assign an owner.

Task state:

• task_type: benchmark control-plane investigation
• task_complexity: normal
• current_phase: closeout
• current_phase_status: complete
• next_phase: final response
• goal_status: active

Current verdict:

• verdict: complete
• confidence: high
• next owner: adapter coverage
• reason: fresh issue-shaped clipboard artifact passes thresholds and health now has zero over-budget rows.

Completion rule:

• Do not call update_goal(status: complete) while any required checklist item remains unchecked. If an item does not apply, check it and add N/A: <reason>.
• Do not call update_goal(status: complete) until every completion threshold above is satisfied, final handoff evidence is recorded, and node .agents/rules/autogoal/scripts/check-complete.mjs docs/plans/2026-05-28-investigate-evidence-kit-over-budget-rows.md passes.
• Do not create hook state for this goal. This file plus the active goal are the durable state.

Findings:

• Over-budget rows were cutTwoBlocksEditMsP50 and cutTwoBlocksMsP50 from slate-clipboard-large-payload-threshold.
• They came from .tmp/slate-v2/tmp/slate-clipboard-large-payload-benchmark.json and the registered clipboard-large-payload artifact.
• The registry command used default mode, which does not reproduce the issue-shaped 50,000-block threshold artifact.
• Fresh issue-shaped run passed: 145.74ms against 150ms, 147.1ms against 250ms, operationCount=1.

Decisions and tradeoffs:

• Treat this as stale artifact plus weak registry command, not as current Slate runtime debt.
• Keep the strict thresholds. The right fix is reproducible refresh command, not loosening budgets.

Implementation notes:

• Updated benchmark-registry.json command for clipboard-large-payload.
• Added iterations/004-clipboard-over-budget-investigation.md.
• Regenerated Evidence Kit result/docs outputs.

Review fixes:

• No review findings. The main self-review point was avoiding a false green by preserving the issue-shaped env in the registry command.

Verification evidence:

• .tmp/slate-v2: SLATE_CLIPBOARD_BENCH_HUGE_CUT_BLOCKS=50000 SLATE_CLIPBOARD_BENCH_ISSUE_TARGETS=1 bun run bench:core:clipboard-large-payload:local passed.
• Fresh thresholds: cutTwoBlocksEditMsP50=145.74ms < 150ms, cutTwoBlocksMsP50=147.1ms < 250ms, operationCount=1.
• benchmarks/editor: npm run evidence:refresh passed and reported nextActions=9.
• benchmarks/editor: npm run docs:perf:check passed.
• Registry JSON parse passed.
• pnpm exec biome check benchmarks/editor/research/benchmark-registry.json --fix passed with no fixes.
• Served http://127.0.0.1:8765/index.html returned 200, no over-budget action, adapter action present, health present.

Final handoff contract:

• PR line: N/A, no PR requested.
• Issue / tracker line: N/A, no tracker target.
• Confidence line: high.
• Flow table:
  • Reproduced: over-budget health rows traced to clipboard artifact.
  • Verified: fresh issue-shaped rerun and Evidence Kit refresh removed over-budget rows.
• Browser check: served static index smoke passed.
• Outcome: over-budget action is gone; next action is adapter coverage.
• Caveat: no Slate runtime optimization was done because current issue-shaped rerun passes.
• Design:
  • Chosen boundary: registry command and iteration note.
  • Why not quick patch: simply rerunning default command would erase thresholds and create a fake green.
  • Why not broader change: current benchmark passes, so runtime work would be speculative.
• Verified: benchmark rerun, Evidence Kit refresh, docs check, served index smoke.

Final handoff / sync:

• PR: N/A
• Issue / tracker: N/A
• Browser proof: served index smoke only
• Caveats: no interactive Browser tool was available after tool discovery; Node fetch verified the already-served local page content.
