• lsp/discovery.py — LanguageDiscovery with 4-layer detection (extension, shebang, UKO, project config)
• features/lsp_functional_runtime.feature — 27 Behave BDD scenarios
• robot/lsp_functional_runtime.robot — 6 Robot integration tests

Modified files

• lsp/runtime.py — Replaced stubs with real LSP calls via lifecycle manager
• lsp/tool_adapter.py — Runtime-delegating handlers with local-mode fallback
• lsp/__init__.py — Updated exports
• features/consolidated_misc.feature — Updated runtime test assertions

Code Review — PR #1044 feat(lsp): implement functional LSP runtime

The largest of the three hamza.khyari PRs at +2,336 lines, but the architecture justifies the scope. Clean separation: StdioTransport (process I/O) → LspClient (protocol) → LspLifecycleManager (reference counting + health) → LspRuntime (orchestration). The LanguageDiscovery module with 4-layer detection (extension map, shebang, UKO, project config) and 70+ language mappings is thorough.

27 Behave BDD scenarios + 6 Robot integration tests provide strong coverage. The replacement of LspNotAvailableError stubs with real LSP calls is a significant capability upgrade.

Approved. No issues found.

Day 43 Review — Rebase Required

This PR has merge conflicts with master and cannot be merged in its current state. This is one of 9 Hamza PRs in the resource/LSP domain (v3.5.0-v3.6.0) that all have conflicts. These PRs likely share a common dependency chain and should be rebased sequentially.

@hamza.khyari: Please rebase onto current master. If multiple PRs depend on each other, start with the base PR in the chain and work upward.

Rebase priority: HIGH — these PRs represent significant feature work that is blocked by merge conflicts. Every day they remain conflicted is a day they cannot be reviewed or merged.

Clear labels   

auto/needs-reevaluation

Controller deferred this PR; awaiting Phase 6+ scope-evaluator or operator re-enablement.

  

controller-managed

Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.

  

auto/blocked-by-deps

PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.

  

auto/ci-timeout

Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.

  

auto/claimed-implementer

Currently being processed by an implementer worker.

  

auto/claimed-merge

Currently being processed by the merge driver.

  

auto/claimed-reviewer

Currently being processed by a reviewer worker.

  

auto/driver-down

Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.

  

auto/invariant-violation

Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.

  

auto/last-attempt-tier-0

In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.

  

auto/last-attempt-tier-1

In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.

  

auto/last-attempt-tier-2

In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.

  

auto/last-attempt-tier-min

In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

  

Automation Tracking

Tracking issues used by the AI Automation system for agents to communicate and report.

  

auto/needs-conflict-resolution

Rebase conflict needs LLM conflict-resolver.

  

auto/needs-implementer

Failing CI needs implementer attention.

  

auto/postmortem

Documenting a driver incident or rollback.

  

auto/ready-to-merge

Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.

  

auto/restart-throttled

Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.

  

auto/revert

Revert PR backing out an invariant violation. Fast-tracked through the merge driver.

  

auto/sentinel

Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.

  

auto/stale-inactivity

No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.

  

auto/unstable

Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.

  

Blocked

A ticket in a blocked state and unable to complete until some other task is completed first.
