 - Added display-cell width template filters for terminal layouts: `cell_width`, `cell_fit`, `cell_pad`, `cell_rpad`, and `cell_truncate`. ([#terminal-cell-width](https://github.com/lbliii/milo-cli/issues/terminal-cell-width))
 - Added display-cell exact topology filters for terminal templates: `rule_line`, `divider_line`, `bottom_rule`, `frame_line`, `rail_line`, `cell_fill`, `cell_meter`, `open_rule`, `open_rule_divider`, and `open_rule_end`. ([#terminal-open-rules](https://github.com/lbliii/milo-cli/issues/terminal-open-rules))
 - Add silent-exception lint gate and `# silent: <reason>` annotations to prevent unlogged exception swallowing
-- Adopt Kida 0.7 capabilities: `inline_components=True` and `validate_calls=True` defaults in `get_env()`; `enable_capture` opt-in kwarg on `get_env()` for static-site / capture flows; new `milo components` subcommand listing bundled and user-defined template defs (with `--json` for tooling, `--path` to scan extra dirs); `milo.live` re-exports for `LiveRenderer`, `Spinner`, `stream_to_terminal`, `terminal_env`; `kida.get_optimal_workers` now sizes the gateway, registry, and saga executor pools by workload type (IO_BOUND for I/O fan-out, RENDER for saga effects); `{% flush %}` boundaries added to `pipeline_progress` and `pipeline_detail` defs to encode streaming contract; CI gains a template compile-check via `scripts/check_templates.py`; new `examples/liverender` shows `LiveRenderer` outside the App harness; new docs page `usage/live.md`.

 - Agent-first improvements: structured MCP validation errors with argument/constraint context, `form_schema()` introspection helper, `llms.txt` required/optional/default markers, `docs/agent-quickstart.md`, `docs/testing.md`, and `examples/greet/` test template.
 - Agent-native affordances: `milo new <name>` scaffold (app.py, tests, conftest, README), `milo verify <path>` six-check self-diagnosis (imports, CLI located, commands registered, schemas generate, in-process MCP list, subprocess MCP transport), `function_to_schema(..., warn_missing_docs=True)` surfacing undocumented typed params, README examples index with drift lint, and a Python 3.14+ preflight on `milo` with an actionable install hint instead of ImportError.

 - Tightened steward guidance with contract checklists, evidence-backed finding format, collateral update rules, synthesis requirements, and parity-matrix expectations for cross-surface work. ([#steward-contract-checklists](https://github.com/lbliii/milo-cli/issues/steward-contract-checklists))
 - Added scoped AGENTS.md steward guidance for core Milo domains so future agent work has explicit ownership, consultation, and safety routing.
 - Adopt Python 3.14+ patterns: PEP 695 type aliases in middleware, match/case in form key handlers, frozen+slotted dataclasses in tests
-- Bumped to `kida-templates>=0.7.0,<0.8.0`. Kida 0.7 makes `strict_undefined=True` the default — milo's bundled templates already conformed, so no behaviour changes for callers using stock templates. User templates that relied on silent-undefined fallbacks now raise `UndefinedError` at render; opt back into the loose mode by passing `get_env(strict_undefined=False)`.
