Change-detectors, tautologies, source-reading tests, redundant duplicates,
mock-echo tests and dead/unrunnable tests. Per-test rationale in the lane
ledger (category + reason for every removal).
`_suppress_mouse_residue_early()` runs at import time, before
`_apply_profile_override()` sets HERMES_HOME, so the first read of
`display.interface` always saw the default home. The result was memoised
in a cache keyed on nothing, so every later caller — the Termux fast
paths and the TUI launch decision, which all run after the profile is
applied — was pinned to the default home's interface for the whole run.
`hermes -p coder` with `display.interface: tui` in that profile booted
the classic REPL, and the mirror case booted the TUI for a profile that
asked for cli.
Key the cache on the config path it read. The hot path still parses the
YAML once per home, and the first call after the process is re-homed
re-reads the file it should have read.
Fixes#116902
The earlier fix gated _resolve_use_tui, but the EARLY launcher
(_wants_tui_early) decides TUI from display.interface before cmd_chat
runs — so a `display.interface: tui` default still booted the Ink UI for
headless spawns (kanban workers), whose no-TTY bail-out exits 0 →
"protocol violation". Gate the early resolver on a real TTY: headless
stdio never boots the TUI regardless of config; explicit --tui still does.
An inherited HERMES_TUI=1 or a `display.interface: tui` config default sent
kanban workers into the Ink TUI, whose no-TTY bail-out exits 0 without doing
the task — every attempt ended in "protocol violation". Two layers:
- _default_spawn pins `--cli` (highest-precedence interface flag) and strips
HERMES_TUI from the child env (covers older builds on PATH).
- _resolve_use_tui gates ambient TUI prefs (env/config) behind a real TTY;
an explicit --tui still wins so the informative bail-out stays reachable.
Add `display.interface` config key so users can make the modern TUI the
default for bare `hermes` / `hermes chat` without exporting HERMES_TUI=1 in
every shell. Default stays "cli" to preserve current behavior.
Add a `--cli` flag (mirrors `--tui`) so an explicit invocation can force the
classic prompt_toolkit REPL even when `display.interface: tui` is configured.
Precedence (highest first): `--cli` > `--tui`/`HERMES_TUI=1` > config
`display.interface` > classic REPL. Two resolvers enforce it:
* `_resolve_use_tui(args)` — the args-aware resolver used by `cmd_chat`
and the Termux fast-TUI path (uses full load_config()).
* `_wants_tui_early(argv)` — a dependency-free early resolver used by
mouse-residue suppression and the Termux fast paths, which run before
argparse / hermes_cli.config are importable (minimal cached YAML read).
Both `--cli` and `--tui` are registered via `_inherited_flag`, so they are
carried across self-relaunch automatically.
- config: add display.interface ("cli" default), bump _config_version 25->26.
The generic missing-field migration + load_config() deep-merge seed the key
for existing configs; no bespoke migration block needed.
- docs: document --cli flag and display.interface in cli-commands.md and
the TUI user guide.
- tests: new test_default_interface_resolution.py covering resolver
precedence at every layer, early resolver edge cases (missing/garbage
config), parser flags, and relaunch inheritance.
