CB-WP-0011-T01: the inspector shows everything, and a gate says so

The renderer moves out of the play loop into inspect.rs and grows from
24 to 42 of the 43 leaf paths a populated GroundView carries. What it
had been dropping was the whole DARVO state machine, the whole GROUND
practice, the scoring mode, Focus tokens, the discard pile, per-seat
protection, and every part of the outcome except the headline.

The load-bearing half is every_view_field_is_classified, which walks
the serialized view for leaf paths and requires each to be listed as
rendered (with a token the output must contain) or omitted (with a
reason). Paths rather than keys: 'problem' occurs under a DARVO target,
a GROUND choice and a Selection, and a key-set walk would let one of
the three vouch for the other two.

Four M-D1-MUT controls, each red for its stated reason. The
unclassified-field control fired for real on the first run --
players.*.hand, a field the gate's own author had missed.

//! The inspector: one seat's whole picture, rendered as text
//! (CB-WP-0011 T01).
//!
//! Moved out of `table.rs`, where it was born in stage 0 as a prompt
//! header. That is exactly what was wrong with it: written to show a
//! human their legal moves, it showed the six fields a chooser needs and
//! silently dropped the rest of the projection — the whole DARVO state
//! machine, the whole GROUND practice, the scoring mode, the Focus
//! tokens, the discard pile, and every part of the outcome except the
//! headline.
//!
//! **No test could have caught that**, which is the point worth writing
//! down. Every assertion a renderer test naturally makes — "the output
//! mentions round", "the output is non-empty", "P2's hand does not
//! appear" — is satisfied by a render that shows a third of the state.
//! The harness-does-nothing class, in its presentation form.
//!
//! So the renderer ships with [`tests::every_view_field_is_classified`],
//! which walks the *serialized shape* of `GroundView` and requires every
//! leaf path to be listed as either rendered or deliberately omitted. A
//! field added to the projection and forgotten here fails the build.
//!
//! **Stated non-goal, unchanged from stage 0:** no TUI, no colour, no
//! readline. This is the inspectable half of INTENT stage 1; the 2D half
//! needs a rendering port, which needs an ADR, which this pass does not
//! have (see the workplan's tier declaration).

test run against a state where the fields are absent is the same lie in a

**Done 2026-08-02.** The renderer moved to `tools/cb-play/src/inspect.rs`
and now covers **42 of the 43 leaf paths** in a populated `GroundView`,
up from 24. The one omission is `players.*.hand``null` for a
non-viewer seat, where the absence is what `hand N card(s)` renders.
`every_view_field_is_classified` walks the serialized view for leaf
*paths* (not keys — `problem` occurs under a DARVO target, a GROUND
choice and a Selection, and a key-set walk would let one vouch for the
other two). Four controls, each run and each red for its stated reason:
| control | result |
|---|---|
| a field deleted from `render` | `players.*.protection is claimed rendered, but the output has no "protect 2"` |
| a field present in neither list | fired **for real on the first run**`players.*.hand` |
| the walk returns no paths (EXPECT-VACUOUS) | `the walk found 0 leaf path(s) — it is not walking the view` |
| a classified path that no longer exists | `classified path(s) no longer exist in GroundView: ["outcome.nonexistent"]` |
The second is the one worth keeping: the gate caught a field I had missed
while writing the gate, before it had ever been committed.
