N1 (medium-low). Moves the epiphany-pipeline pin to the leaf's new commit
(9d3a3efd), which opens Slug::validate_slug. Huginn's own cultcache-rs pin
is untouched; cargo tree -d still carries exactly one cultcache-rs.
Mind::require_instance now validates the declared name's grammar before
comparing identity, so admission's A1 and every read refuse a bad name
identically, through one door. Mind::open and open_with validate the
declared instance before path_for ever runs, so a Slug carrying `..` and a
path separator (Soul's outer/inner probe) is refused before any store is
created, not after it has already escaped the state root.
require_grammatical_instance and its daemon-side branch in daemon.rs are
deleted: the throwaway PipelineInstance wrapper it built is no longer the
only door onto the leaf's grammar. The refusal now names the field a
caller actually held the declared name under (declared, or instance) and
the whole declared name, not the old wrapper's instance.instance field or
a single failing label.
Adds a leaf-escape regression test pinning Soul's probe and asserting no
store is created, and a fullwidth-instance test showing Admit and Query
refuse identically. Updates the cut10 grammar-fold mutant (S3wide) to the
new function shape and the affected daemon test to the new field name.
N5 and N6, prose only. The cut10 entries gain a note by S1 and S1d: neither
mutant "dies on all three" faults its shared fixture carries, contrary to
an earlier claim; S1d exempts the orphan fault by construction and is
killed by the undecodable-document block instead, the next one the test
body reaches. The cut9 header's self-contradiction at lines 18-25 is
resolved (nothing in the suite exercises the door, not "nothing reaches
it"), its self-reference now points at store.rs:18-19, and its line-1
range is corrected to V1-V24L.
All three suites rerun clean after the pin move: cut8 67/67, cut9 38/38,
cut10 65/65, every M0 green, restores hash-verified. cargo test --workspace:
huginn-mind 61/61 (was 60), huginn-daemon 18/18 (was 17).
