This branch's uncommitted WIP, committed together (entangled at file level). Distinct pieces of work: Freestyle QA fixes (this session): - FileEditTool: pre-validate replace anchor in validateRequest — reject a missing/ambiguous target BEFORE the approval gate, mirroring read/write's file-not-found / read-before-write pre-checks. Shared not-found/ambiguous messages between validate and execute so they can't drift. - PlanGrounder: add `scanned` flag; when no RepoMapComputedEvent was recorded, repoMapPaths is "unknown" not "empty workspace" — skip scope grounding (which proves a path ABSENT) so real paths (apps/server/**) aren't falsely rejected. Build-manifest check still runs. - FreestyleDriver: wire scanned=(repoMap!=null); on plan rejection emit a session-terminal WorkflowFailedEvent so a rejected run reads FAILED, not the COMPLETED-lie (last verdict was the planning-phase WorkflowCompleted). - ServerModule: resolve project-memory workspace root from the session's bound workspace (sessionWorkspaceRoot) instead of boot-static pm.repoRoot(), fixing the workspace-binding divergence (correx vs empty scratch dir). Retire tracked in Vikunja #266. - LaunchRegistrationRaceTest: join registered jobs before asserting launchCount — computeIfAbsent returns the Job immediately but the fire-and-forget launch body lagged awaitAll (the 49-vs-50 flake). ACR concept-compiler experiment (pre-existing WIP on this branch): - ExecutionPlanCompiler/Model/PlanLinter, #264 needs-seam (sessionArtifacts), LSP diagnostics subsystem (LspDiagnosticEvents/Runner/Lsp4j), BootWorkspace, config surface, workflow prompts/schemas, orchestrator advance-don't-rerun.
