The author path's per-surface description slot (July 25, 2026) ----- +# rlms reserves one description line per `custom_tools` entry and fills an +# undescribed one with "A custom value". The research path composed +# that slot from each surface's registered descriptor; this path did not, +# so an author run's one surface reached its model as +# "A custom TrellisWorkspace value" — a type name in the highest-primacy +# text the run sees about what it has, while the coverage diagnostic +# reported the research seam and read as though it meant both. +# +# WHY THE SAME BYTES AS THE RESEARCH LINE, in a regime that is not the +# research one. The line is WORKSPACE_DESCRIPTOR's own `purpose`, and +# WORKSPACE_ADDENDUM — spliced into this very prompt by +# build_author_system_prompt — already opens by calling the surface the +# model's working memory for plan, self-notes, and captured external +# results. The slot therefore states nothing this prompt does not already +# state, and a second characterization composed for this path would put +# two readings of one surface into one prompt +# (SELF_DESCRIBING_SURFACES.md §9.1).

The derivation reads WHAT THE COMPOSING CALL +DRAWS FROM, so it distinguishes a call that iterates the seam itself +(every injected surface is wired, by construction) from one naming +surfaces literally (only those are wired, and a surface added to the +seam stays unwired until it is named there too). + +AND WIRED IS STILL NOT DELIVERED. The three rungs are per-surface and +they stop at the composing call.

Delivery is a chain inside ONE +function, so there are as many delivery answers as there are functions +composing — and a read returning one of them names a property of one run +mode while reading like a property of the file. This module derived +exactly that for a while: it took the LAST composing function and called +its answer the answer, which was harmless only because the second mode +composed nothing at all. `_composing_scopes` returns them all, +`derive_delivery` answers per seam and reports `delivered` as the +conjunction, and `format_coverage` names each seam, so a mode that stops +delivering cannot hide behind a sibling that still does. + +A RUN MODE THAT RENDERS WITHOUT COMPOSING is the shape that state was in +before anyone noticed, and it is invisible to every read above: its +surfaces are not in the injected roster (they arrive through a factory, +named under `dynamic_sources`), it owns no composing call for the wired +rung to read, and its delivery answer does not exist to be false. +Everything reads closed and its model reads type names. +`derive_delivery` therefore also reports `rendering_without_composing` — +functions handing the renderer a `custom_tools=` with no composing call +of their own — which is derived from the same parse and is the one +condition that names a whole run mode rather than a surface. + +The seam keeps one hand-kept roster below the derived one: `_expects`, +which supplies the guard-owned phrases an ('expects', key) slot resolves +through.
