Plan tracker: 8p-a parallel li-tests + Vision-LLM agent manifest slice

Status: Ready for review
Repo: li-langverse/lic
PH / REQ: Phase 8p-a, Vision-LLM (master plan tracker)

Summary

Ships parallel li-tests orchestration with isolated LI_BUILD_DIR per worker (8p-a) and a compact JSON export of the test manifest for agents (Vision-LLM partial).

Agent continuation

  1. Read: docs/superpowers/plans/2026-05-22-parallel-compile-ci.md § 8p-b–d; docs/superpowers/plans/2026-05-14-li-master-plan.md tracker.
  2. Run: ./scripts/build.sh && ./li-tests/tooling/run_all_parallel_smoke.sh && LI_TEST_JOBS=2 ./li-tests/run_all.sh math_linalg && ./li-tests/tooling/agent_manifest_smoke.sh
  3. Then: 8p-b parallel workspace (lic-workspace-build.sh); wire lic build --jobs to MIR passes (8p-c).
  4. Blocked on: full 8p wall-time SLO measurement on 8-core Linux (log to docs/ecosystem/lic-ecosystem-baseline.md).

Changed

Area What Evidence
8p-a LI_TEST_JOBS, -j N, isolated LI_BUILD_DIR li-tests/run_all.sh, scripts/lib/li-jobs.sh

Not changed

  • Phase 2i, 7d, 7e implementation — tracker text only elsewhere.
  • provability-gaps.md body — no edits.
  • Phase sub-plan checkboxes — not bulk-edited.
  • lic build --jobs frontend parallelism (8p-c) — flag still reserved.
  • Workspace parallel builds (8p-b).

Breaking changes

None.

Security

N/A — test orchestration only; no trusted surface change.

Performance

Parallel run_all.sh reduces wall time when LI_TEST_JOBS>1; default remains 1 locally, host cores when CI=true. No bench ratio claims in this PR.

CHANGELOG entry

### Added
- **8p-a (partial):** parallel `li-tests/run_all.sh` with `LI_TEST_JOBS` / `-j` and per-worker `LI_BUILD_DIR` — `docs/release-notes/2026-05-25-plan-tracker-8p-vision-llm.md`.
- **Vision-LLM (partial):** `li-tests/agent-manifest.json` export for agents — `scripts/export-li-tests-agent-slice.sh`.
