K3-23 measured the whole decomposition and landed on one recommendation:
the cost is the PATH, not the link. 39 of 39 newcomers that won a question
token from the door's `Enclosing section:` line won it through the
bundle-absolute path and 0 of 39 through the link's title, and every token
the path ever contributed is a segment of the document's own directory --
the saturation `shared_id_prefix` took OUT of the id signal, back in through
the body.
Ten cases, each red for its own reason on `7faa380`, and each one measuring
BEHAVIOUR rather than a signature: the three entry points are called with no
parameter at all and what came back is read.
- `searchable_text`, `concept_scores` and `build_payload` with no parameter
read a body without the door's line (3 cases).
- The declared default IS the behaviour: the constant is imported from the
module that owns it, INSIDE the test so the red falls on the rule and not
on collection, and then spent on a payload comparison.
- Y = Z in miniature: the flagged bundle read by default delivers the same
list, the same ORDER and the same `spent` as the unflagged build.
- `link_in_signal=True` is still reachable and still does the old thing --
both halves, because either alone would pass on a no-op.
- The two known-negatives restated against the DEFAULT path: a human line
opening with the same two words, and the door's exact form anywhere but
last, keep every byte.
- Rank, never form: the two readings differ in the delivered set while every
concept delivered by both carries identical excerpt bytes.
Two stay green on both sides on purpose. The known-positive -- a bundle where
no body ends in the door's form is byte-identical under both readings -- is
section 4A's exposure gate in miniature and would go red only if the stripper
became eager. The characterisation of what the line does today is HEAD's
behaviour and keeps stating it.

`inbox._link_enclosing` appends one line to a heading-only body; `consume._body`
returns everything after the frontmatter, so the line is scored by the body
signal and counted by the lexical gate. Nothing in the code ever decided that:
SPEC SS 6.1's argument for the bundle-absolute form is about the FILE.
One characterisation, green on HEAD, holds the mechanism: a shell whose own
text answers nothing in the question still scores, on the door's line alone.
The eight red ones ask for the instrument K3-23 needs -- one bundle, two
readings, in one process -- and for its two obligatory known-negatives: a human
line opening with the same two words, and the door's exact form anywhere but
last, both keep every character they have.
