v3.14.0

Minor. Step mode and governed parallelism. You can now supervise the orchestra iteration by iteration — and parallel HU execution, which previously ran unbounded, is capped, budgeted and opt-in.

Added

• Per-iteration gate — kj run --step (KJC-TSK-0628): the pipeline pauses after EVERY iteration with a compact report — iteration n/max, the reviewer's verdict with its must-fix list, what the next iteration will do, spend vs cap — and asks: Enter continues, stop stops (resumable with kj resume), and any other text becomes a directive injected into the feedback the coder reads next iteration, never clobbering the reviewer's own list. Also offered as a question in the kj init wizard; unattended autonomous runs pass through.
• Governed parallel HU execution — kj run --parallel <n> (KJC-TSK-0622..0626): plans can run HUs concurrently, each in its own git worktree under .karajan/worktrees/, scheduled over the blocked_by graph with conservative scope isolation (overlapping or scopeless HUs never run together), a shared semaphore, and a plan-level budget ceiling (n × max_budget_usd) that stops the batch loudly when exhausted. The SonarQube stage serializes across lanes.

Fixed

• Parallel execution is now bounded — default 1, fully sequential (KJC-TSK-0626, related to KJC-BUG-0107): the HU sub-pipeline used to launch dependency groups with an UNBOUNDED Promise.all — a plan with N independent HUs ran N full coder pipelines at once, with no cap and no shared budget. That path is now opt-in and governed; the safe sequential behaviour is the default.
