chore(lsp-pilot): retire the LSP pilot after Shell NO-GO (#839, #845)

[don-petry]

What & why

Repins the LSP pilot's frozen comparative corpus (evals/lsp-pilot/holdout/cases.jsonl) from synthetic seed PRs to 20 real merged PRs from this repo, pinned by their true headRefOid. This is the "swap in the real pilot PR set" step the corpus README always anticipated, and it unblocks the go/no-go decision on #845 — which cannot honestly be recorded against synthetic seed data.

Part of epic #839. This PR changes only the eval corpus + docs — no engine/workflow behavior changes.

The corpus (stratified by navigation intensity, not defect archetype)

The pilot's success metric is navigation-token reduction with no precision regression — driven by cross-file navigation during review. So the 20 are stratified by how much navigation a correct review demands:

Stratum	Count	PRs
High-nav cross-file (shared scripts/lib/*.sh helper → follow to callers in other files)	12	#528, #928, #453, #379, #468, #649, #720, #784, #592, #658, #609, #1012
Medium-nav (self-contained helper logic, bounded callers)	3	#460, #1011, #494
Diagnostics (genuine publishDiagnostics hit)	1	#196
No-navigation control (docs-only)	4	#1065, #953, #867, #847

Why the original archetypes were dropped

An exhaustive sweep of real history (300 merged + all closed-unmerged shell PRs, two independent agents) found the original synthetic slots cannot be filled from real history:

• Unused-symbol removal & cross-file rename — no organic example in-window (nearest matches are file-level removals or full rewrites, not the target shapes).
• Syntax-error / SC2154 diagnostics — a blocking shellcheck --severity=warning -x CI gate has run on every push since ~2026-05-16 (feat: Actions Fleet Monitor — pure telemetry, shim interface, docs, lint #197), so no such defect survives to any PR head, merged or closed.

The one diagnostics case that does survive is PR #196: 5× SC2086 word-splitting in pr_review_health.sh, which slipped the gate because SC2086 is info-level. bash-language-server surfaces it as a real diagnostic — the single legitimate defect-verification case in real history.

Baseline / runs retired

The synthetic baseline-lsp-off.jsonl and runs/*.jsonl were keyed to the now-removed #701–706, so they're emptied rather than left dangling. The real A/B runner (scripts/lsp_pilot_run.sh) captures the LSP-off and LSP-on legs live on the same real PRs in one run, so the comparison does not depend on a pre-committed frozen baseline. docs/lsp-pilot-report.md is banner-marked superseded.

Decision surfaced for reviewers

The original design (#841) kept an immutable frozen LSP-off baseline as an anti-reward-hacking anchor. The #844 live A/B runner supersedes that by generating both legs live. This PR retires the frozen synthetic baseline; if you want to retain the frozen-baseline discipline, the first real LSP-off capture over these 20 PRs should be committed once and thereafter treated as immutable. Flagging rather than deciding unilaterally.

Next step (not in this PR)

Run scripts/lsp_pilot_run.sh over the repinned corpus per candidate server (within the ≤120 deep-tier-run cost cap), render the real report, then record the human go/no-go on #845.

Validation

• validate-cases.py evals → green (43 cases across dev+holdout, no cross-split id overlap)
• 20 holdout + 2 dev cases JSONL-well-formed
• tests/lsp_pilot_compare.bats + tests/lsp_pilot_report.bats → pass (use fixtures, not committed data)
• holdout-guard: human/donpetry-bot author passes; github-actions[bot] proposer still blocked (guard intact)
• PR fix(dev-lead): rate-limit detection, separate status, and retry cron (#192) #196's SC2086 confirmed present at the pinned head SHA via shellcheck

📝 Walkthrough

Walkthrough

Documentation and evaluation datasets for the LSP pilot are updated to repin the holdout/dev corpus to real merged PRs stratified by navigation intensity, mark synthetic baseline/candidate runs as retired/emptied, add a Go/No-Go decision section (NO-GO for Shell), and flag the existing report as superseded.

Code Review

This pull request updates the LSP pilot evaluation setup by repinning the evaluation corpus from synthetic seed data to 20 real merged pull requests from the repository, stratified by navigation intensity. It updates the documentation in docs/lsp-pilot-report.md, docs/lsp-pilot.md, and evals/lsp-pilot/README.md to reflect this change, replaces synthetic smoke cases in evals/lsp-pilot/dev/cases.jsonl with real ones, and retires the synthetic baseline and candidate runs in baseline-lsp-off.jsonl, agent-lsp.jsonl, and serena.jsonl to empty. There are no review comments, so I have no feedback to provide.

[Copilot]

Pull request overview

Repins the LSP pilot’s held-out comparative corpus to real, merged PRs (pinned by head_sha/headRefOid) and retires the prior synthetic baseline and seed run captures, updating documentation to reflect the new corpus composition and the “empty pending real capture” status.

Changes:

• Replace evals/lsp-pilot/holdout/cases.jsonl with 20 real merged PR cases stratified by navigation intensity.
• Update evals/lsp-pilot/dev/cases.jsonl smoke cases to real PRs and retire synthetic seed artifacts by emptying the baseline and prior candidate run JSONLs.

Review mode: triage-approved (single reviewer)

Summary

Core LSP-corpus repin (commit 4f65d90) is sound and well-documented, but the head commit 9a2d096 (dev-lead 'review-changes' bot commit, [skip ci-relay]) bundled unrelated initiative-planner files from issue #706/epic #597, contradicting the PR description, conflicting with main, and leaving the lint CI gate unrun on the head SHA.

Linked issue analysis

No closing-issue references. The PR is part of epic #839 and unblocks the go/no-go on #845. The corpus repin substantively advances the epic: 20 real merged PRs pinned by true headRefOid, stratified by navigation intensity, with a documented rationale for dropping the original synthetic defect archetypes. The frozen-baseline retirement decision is explicitly surfaced for human reviewers rather than decided unilaterally — appropriate.

Findings

1. [BLOCKING] Cross-PR contamination in head commit. Commit 9a2d096 ("chore: dev-lead update (review-changes) [skip ci-relay]") added tests/test_plan_materialize.bats, tests/fixtures/initiative-planner/plan-581-accepted.json, and a .github/workflows/lint.yml hunk — all belonging to the plan-materialization work (issue [Phase 3] Materialize accepted critic findings as sub-issues + native blocked_by edges (not just gate) #706, epic Initiative: Adversarial plan-critic + structural gates for the initiative-planner (Bob) #597), not this LSP-corpus PR. This contradicts the PR body's claim of "only the eval corpus + docs — no engine/workflow behavior changes". The bats file is byte-identical to the copy now on main (blob 84d5fe2), and the lint.yml line already exists on main — but the fixture JSON differs from main's copy (e7835b3 vs ed48d3b), which is the source of the merge conflict.
2. [BLOCKING] Merge state CONFLICTING/DIRTY. The PR cannot merge as-is. Fix: rebase onto main and drop the contaminated files (they already landed on main via their own PR); do not hand-resolve the fixture divergence in this PR.
3. [BLOCKING] Lint CI did not run on the head SHA. Only CodeQL and dependabot-automerge ran on 9a2d096; the [skip ci-relay] bot push meant the shellcheck/bats lint workflow and gitleaks never validated the head commit. "All checks green" is not satisfied — the primary gate is absent, not passing.
4. [INFO] No security concerns in content. The corpus/docs changes are data + markdown; pinned SHAs are immutable identifiers from this repo's own history. No secrets in added content by inspection; the run_secret_scanning MCP tool was unavailable in this run.
5. [INFO] Prior bot reviews (gemini, Copilot) reviewed 4f65d90, not the head. Copilot generated 4 comments on the earlier commit; the dev-lead follow-up's only in-scope delta was +1 line in docs/lsp-pilot-report.md — resolution of those threads should be re-verified after the rebase.

Recommended remediation: rebase onto main; drop tests/test_plan_materialize.bats, tests/fixtures/initiative-planner/plan-581-accepted.json, and the lint.yml hunk from this branch (all superseded by main); push normally so the full lint workflow runs on the new head.

CI status

CodeQL Analyze (actions) ✓, Analyze (python) ✓, CodeQL ✓, CodeRabbit status ✓ (review itself rate-limited, not performed), dependabot-automerge skipped. Lint (shellcheck + bats) and gitleaks absent on head SHA 9a2d096 — the bot push used [skip ci-relay], so no lint validation of the final commit exists.

Update — pilot run complete, NO-GO decision folded in (commit d0ae64f)

Ran the real comparison over the repinned 20-PR corpus (live A/B, agent-lsp v0.15.0 + bash-language-server 5.6.0), then recorded the scoped go/no-go in docs/lsp-pilot.md §7:

Run	Model	Agg nav-token ratio	High-nav	Cold-start
28718240665	sonnet-4-6	1.26×	1.01×	2.9s
28940391169	opus-4-8 (prod)	1.05×	1.04×	4.1s

NO-GO for Shell/bash-language-server — the ≥2× token clause fails decisively on both the exploratory and production-tier runs; high-nav is a wash at ~1.0×. Cold-start passes. Decision is scoped to this one language/server; the door is explicitly left open for TypeScript/Python/Go, and the measurement harness stays in-repo (dormant) for a per-language re-pilot. Production wiring is inert (no mcp__lsp__ in REVIEW_MCP_ALLOWED_TOOLS; LSP_PILOT_ENABLED unset), so pr-review is byte-for-byte unchanged.

This PR now covers the full closeout: repin corpus → run → record decision. Merging it satisfies #845.

Summary

Re-review after prior fix-request (cycle 1 reviewed 9a2d096). The only new commit is a well-written, docs-only NO-GO decision record in docs/lsp-pilot.md (+59/-1) — it introduces no new issues, but NONE of the three blocking findings from the prior review were addressed: the branch still carries the unrelated initiative-planner files, is still CONFLICTING with main, and the lint/gitleaks CI gate still never ran on the head SHA.

Linked issue analysis

No closing-issue references. Part of epic #839; the new commit records the scoped go/no-go decision for #845 (NO-GO for Shell/bash-language-server, evidenced by two live A/B runs, wiring left inert). The decision record substantively advances the epic and its scoping is careful and explicit. This does not change the mergeability blockers.

Findings

Status of prior findings (prior review at 9a2d096):

1. [BLOCKING — UNRESOLVED] Cross-PR contamination. tests/test_plan_materialize.bats (+179), tests/fixtures/initiative-planner/plan-581-accepted.json (+115), and the .github/workflows/lint.yml hunk are still on this branch. The fixture JSON still differs from main (blob e7835b3 on head vs ed48d3b on main) — this remains the source of the merge conflict. Remediation from the prior review (rebase onto main, drop these files — they already landed via their own PR) was not applied.
2. [BLOCKING — UNRESOLVED] Merge state CONFLICTING/DIRTY. The PR still cannot merge.
3. [BLOCKING — UNRESOLVED] Lint CI absent on head SHA. On d0ae64f only CodeQL (actions+python) and dependabot-automerge (skipped) ran; the shellcheck/bats lint workflow and gitleaks never validated this head either. The primary gate is absent, not passing.
4. [RESOLVED-N/A] New commit content is clean. The single new commit (docs/lsp-pilot.md NO-GO record) is markdown-only, internally consistent with the run evidence it links, and introduces no engine/workflow behavior changes. No new issues.
5. [CARRIED FORWARD — INFO] Copilot review threads from commit 4f65d90 should be re-verified after the rebase.
6. [INFO] Secret scan: the run_secret_scanning MCP tool is unavailable in this run; a pattern-level inspection of the diff found no secrets (content is eval-corpus JSONL with immutable in-repo SHAs, markdown docs, and bats tests).

Remediation (unchanged from prior review): rebase onto main; drop the three contaminated files/hunks (superseded by main); push normally (no [skip ci-relay]) so lint + gitleaks run on the new head.

CI status

On head d0ae64f: CodeQL Analyze (actions) ✓, Analyze (python) ✓, CodeQL ✓, CodeRabbit status ✓, dependabot-automerge skipped. Lint (shellcheck + bats) and gitleaks did not run on the head SHA — same gap as the prior cycle. Merge state: CONFLICTING/DIRTY.

Summary

Retires the LSP review pilot (epic #839) after the Shell NO-GO recorded on #845. Net -4,497 lines across 38 files: 27 pilot-dedicated files deleted (evals/lsp-pilot/, scripts/lsp_pilot_.sh, setup-lsp-pilot.sh, lib/lsp-verification.sh, .github/mcp/lsp.json, lsp-pilot-run.yml workflow, docs, all LSP tests) and 11 shared files surgically stripped of pilot hooks (engine.sh, review-one-pr.sh, token-metrics.sh, pr-review.yml, lint.yml, test-dev-lead.yml, both review prompts, two test files). All strips restore exact pre-pilot behavior.

Linked issue analysis

No closing keywords, by design — #839 is the epic and #845 is the go/no-go story. The NO-GO decision (bash-language-server / Shell, door left open for other languages) is recorded on #845 with metric evidence from two independent live A/B runs over the 20-PR real corpus (agg nav-token ratio 1.26x / 1.05x — no reduction, failing the pilot's success metric). This retirement is the owner-directed follow-through on that decision. Note: #845's decision record cites docs/lsp-pilot.md §7, which this PR deletes; the evidence tables are duplicated in the #845 comment itself, so the record survives in the issue as intended ("knowledge preserved in the issues, not the tree").

Findings

No blocking findings.

Verification performed:

• Grepped the full tree at head SHA for lsp_pilot|LSP_PILOT|lsp-pilot|lsp-verification|_lsp_pilot|lpe_variant|mcp/lsp.json — zero dangling references outside deleted files. token-metrics.sh correctly retains its non-pilot core (emit_token_record) with only emit_verification_record removed.
• engine.sh strip restores unconditional --output-format json and direct parse_engine_usage claude "$final_stdout" — byte-equivalent to pre-pilot behavior for all consumers.
• pr-review.yml removes the lsp_pilot_variant workflow_call input: verified no remaining in-repo caller passes it (the forwarding trigger stub lsp-pilot-run.yml is deleted in this same PR), and the pilot was opt-in with consumer repos never setting it.
• Workflow changes are pure removals of opt-in steps/env — no new actions, permissions, or triggers introduced.
• Test deletions are all pilot-scoped; the ack-test-deletion label is present. Remaining edits to test_holdout_guard.bats and test_mcp_connectivity_check.bats only drop/replace pilot fixtures; the guard mechanism tests remain intact.
• Delta since last reviewed SHA (dd3c6f3): only a merge of main bringing in the unrelated tests/test_push_protection.bats — PR content unchanged.

Non-blocking notes:

1. The PR body still describes the earlier repin phase; the 2026-07-09 repurpose comment documents the retire scope. Consider updating the body before merge for a clean squash-commit message.
2. Prior review cycles 1–3 posted fix-requested verdicts with empty findings sections (a template artifact, not real issues), which is why the cascade failed to converge — nothing substantive was outstanding.
3. Secret-scan MCP tool unavailable this run; gitleaks CI check is green and the diff is ~pure deletion (7 added lines, all restored pre-pilot code or fixture renames).

CI status

All required checks green at 5aa1845: shellcheck, ShellCheck, bats, unit-tests, unit, Lint, CodeQL (actions + python), SonarCloud Quality Gate passed (0 new issues), Secret scan (gitleaks), agent-shield, holdout-guard, validate-fixtures, gh-aw-compile, all guard/permission/stub-structure checks. CodeRabbit: APPROVED (2 earlier minor comments resolved). Skipped jobs are ecosystem-conditional (npm/pip/cargo audits) — expected.
