   - _Depends: 10.3, 10.4_
   - _Verified: 2026-08-06 — `cli.py` (design.md's exact target file) adds `@cli.group() scheduler`, `@scheduler.group("record") scheduler_record` (start/stop/status), and `@scheduler.command("dump") scheduler_dump` — matching the literal surface `xceadmin scheduler record start [FILE]`/`record stop`/`record status`/`scheduler dump <FILE>` exactly (verified via a live `CliRunner --help` smoke test at every level, not just read). CLI function names are prefixed (`scheduler_record_start` etc., not bare `record_start`) specifically to avoid shadowing the directly-imported `xceadmin.scheduler.record_start`/`record_stop`/`record_status`/`dump` functions they delegate to — click infers the CLI-visible command name from the decorator's explicit string argument, not the Python function name, so this is invisible in `--help` output (logged as a do-not-repeat in cerebrum.md: same bare name would compile fine but recurse infinitely at call time). Pure delegation + formatting only, no business logic: `record_start`/`record_stop`/`record_status`/`dump` are called unmodified; a new `_format_record_result()` renders `RecordResult` in requirements.md AC 10's exact "Status output" column-13 layout (pinned by a verbatim-reproduction test), shared by all three record subcommands per AC 10's "returned by recordStart/recordStop for confirmation" wording. Error handling: the existing `except XceAdminError as e: raise click.ClickException(e.message)` catch-all (config_push's precedent) is reused as-is for `scheduler dump`'s `ReplayFileError`/`SchemaNotFoundError`; the three `record` subcommands add one narrower branch ahead of it — `except SchedAdminError` — since `SchedAdminError`'s own docstring (task 10.3) explicitly documents that its `recording`/`file`/`event_count` state is meant to be surfaced richer than a bare message (e.g. "already recording" alone doesn't say which file); enriched only when `e.recording` is true (the only case with genuinely useful extra state — "not recording"/"scheduler not connected"/"request timeout"/"invalid record file name" all report `recording=false` and fall through to the plain reason string, matching precedent). `OSError`/`KeyboardInterrupt` handling mirrors `config_push`'s existing branches verbatim (same underlying `wire.connect` socket pattern). New tests in `test_cli.py` (19 added, all monkeypatching `xceadmin.cli`'s imported `record_start`/`record_stop`/`record_status`/`dump` bindings rather than a mock TLS server — full mock-server/redirect coverage is task 10.6's job): `--help` reachability at every group level, direct unit tests of the three formatting/error-translation helpers (incl. a verbatim requirements.md-example reproduction), argument/option parsing and delegation (explicit filename + `--controller`), success-output formatting for all three record actions, `SchedAdminError` enrichment vs. plain-message fallback, connection-timeout/connection-refused/`KeyboardInterrupt` all becoming clean `ClickException`s not raw tracebacks, and `dump`'s exact-text echo (`click.echo(text, nl=False)`, since `dump()` already ends its own text with `\n`) plus its error translation. Verified via the real `meson compile -C xce.build xceadmin` command (custom_target wrapping `meson-build.sh`'s pytest run): 220 passed, 3 skipped (up from 201/3 pre-task; the 3 skips are the same pre-existing live-cluster E2E tests, unaffected) — zero failures, zero new skips. No linter/formatter is configured for this package (re-confirmed, matching task 10.4's prior finding) so none was invented/run.
 
-- [ ] 10.6 xceadmin scheduler CLI tests
+- [x] 10.6 xceadmin scheduler CLI tests
   - Test record start/stop/status against a mock TLS server (including redirect-following) and dump against a fixture replay file
   - Observable: the test suite passes for all four commands, including at least one redirect-following case
   - _Requirements: 5.10_
   - _Depends: 10.5_
+  - _Verified: 2026-08-06 — new `test_cli_scheduler_mock.py` (377 lines) closes the exact gap task 10.5 left open: real `click.testing.CliRunner` invocations of the actual `cli` entrypoint against real local TLS mock servers, zero monkeypatching of `scheduler.py`/`cli.py` bindings — distinct from `test_scheduler.py`'s function-level mock-server tests (10.3/10.4) and `test_cli.py`'s monkeypatched CLI tests (10.5). Covers all three record actions plus a genuine two-server standby→primary redirect handoff (`test_cli_scheduler_record_start_follows_redirect_to_primary`), a real `SchedAdminError` raise-site error path, and `dump` against a real on-disk `.replay` fixture built via pycapnp's write-side API. No production code changed (`cli.py`/`scheduler.py` untouched, confirmed via `git diff`). 227/227 passed, 3 skipped (baseline 220/3, +7 new, 0 failed, 0 new skips) via `meson compile -C xce.build xceadmin`. Review APPROVED first pass, zero findings. Closes out Group 10 (Integration: Controller Admin Opcode and xceadmin CLI) entirely — tasks 10.1-10.6 all complete._

+"""Full-stack CLI + mock-TLS-server tests for the ``scheduler`` command
+group (design.md, ``XceAdminSchedulerCLI``; task 10.6, Requirement 5.10).
+
+Every ``scheduler``-related test in ``test_cli.py`` monkeypatches the
+imported ``record_start``/``record_stop``/``record_status``/``dump``
+bindings on ``xceadmin.cli`` directly (task 10.5's own coverage,
+deliberately left at the CLI-wiring layer only -- see that file's own
+comment and task 10.5's tasks.md ``Verified`` note: "full mock-server/
+redirect coverage is task 10.6's job"). This file closes that gap: it
+invokes the REAL ``click.testing.CliRunner`` entry points
+(``scheduler record start/stop/status``, ``scheduler dump``) with NO
+monkeypatching of ``xceadmin.scheduler``'s functions, backed by a real
+local TLS mock server (record commands) or a real fixture ``.replay``
+file on disk (dump). This proves CLI arg parsing -> ``scheduler.py`` ->
+``xceadmin.discovery.follow_redirects``/``decode_reply`` ->
+``xcecommon.wire`` actually compose end to end through the click entry
+points, including at least one real standby -> primary redirect handoff.
+
+Does not re-test ``scheduler.py``'s own request/reply/error-mapping logic
+in isolation (``test_scheduler.py``'s mock-server tests already cover
+that at the function level) or ``cli.py``'s argument-parsing/error-
+translation logic in isolation (``test_cli.py``'s monkeypatch section
+already covers that) -- only their real composition.
+
+Split into its own file (rather than appended to ``test_cli.py``) to keep
+both files under this project's 800-line file-size guideline -- mirrors
+this suite's existing precedent of ``test_config_push_mock.py`` being
+split out from ``test_cli.py``'s ``config`` tests, and each mock-server
+test file (``test_config_push_mock.py``, ``test_scheduler.py``, this
+file) being self-contained with its own local ``_MockController``/
+``mock_controller`` fixture rather than a shared one (``test_scheduler.py``
+module docstring: "not shared across test files since pytest fixtures/
+helpers are conventionally module-local in this test suite").
