Move DOCK_SHRINK_WEIGHT to the TUI constant directory.
Keep this value in the corresponding constant directory and import it here. This file is TUI logic code.
As per coding guidelines, apps/kimi-code/src/**/!(*.test).ts: “Constants must live in the corresponding constant directory and must not be scattered through component or logic code.”

Select the final JSON object before older fenced objects.
Lines 41-55 add fenced candidates before reverse-scanned objects. A valid object in an earlier code fence is selected before a newer final object. A nested object can also win when it has the same fields as the outer result.
Track candidate positions. Parse candidates by latest closing position, and prefer the outer object when positions are equal. Add coverage for an earlier fenced object followed by a final object.

Validate integer values as integers.
Line 132 accepts 1.5 for a property with type: "integer". This marks a non-conforming result as structured output.
Split the number and integer cases. Use Number.isInteger(value) for integer. Add a fractional-value test.

A subagent's result is prose, so a parent fanning out over many children gets back paragraphs it has to re-read, and no child can build on another's findings. Agent and AgentSwarm now accept result_schema, a flat JSON Schema the child must satisfy by ending its final message with a matching JSON object. Extraction is forgiving — bare object, code fence, or embedded in prose — but validation is not: a value that does not match is reported as missing rather than passed off as structured. The Agent tool surfaces the parsed object in a [structured_result] section, and AgentSwarm replaces each compliant child's prose with its object so a large swarm report is mergeable, keeping the prose plus a marker for children that failed to comply. Fullscreen mode stranded a short transcript at the top of the screen with a dead void between it and the dock, so a fresh session read as a gap with text floating above it. A growable spacer above the ScrollView bottom-anchors the transcript; once it outgrows the viewport the spacer collapses and the ScrollView absorbs the height deficit. The dock's shrink weight is dwarfed by the transcript's, so shrink pressure can never crush the activity and todo rows the way an evenly weighted stack would. Covered by frame-level tests driving a virtual terminal, verified to fail against the previous layout.
