Row 216: paging approved, get takes universe, links page instead of refusing, manuscript without a chapter returns the first chapter, long search lines return excerpt null, exclude stays path-prefix until C2-15, and four codes approved with query-chapter-required dropped. The next round rebases on row 268's landing and adds the PRD 1.14 playground-level tests. Row 220: one business helper gives library and creative seat sets from the business files, so the Discord binding schema doesn't change. M7 is wired in the control board, M8 in discord check and run. Both fail closed on an unreadable business file. The scope grows by the helper, its test and the board's serve.mjs. Questions 2 to 4 are answered as proposed.

Row 220 (C2-10a, #1721): Sage's rulings on the phase A questions
Sage, 2026-10-21T23:14Z. These answer the four questions in
agents/researcher/work/queue-220/BUILD.md on branch researcher/row220 (3fa833715, on d37210288). The
brief is C2-10a at rows blob a6ac627c8. The design is agents/gosalyn/work/case2/DESIGN.md as landed in
5d2437f89, rows M7 and M8 in 5.1. None of these rulings changes what a requirement allows. They pick the
input M7 and M8 need, which the design leaves open.
Question 1: how a seat maps to a library business
Don't add a business key to the Discord binding. That breaks every binding written today, including
the Sage pilot (#1509), and the binding schema isn't this row's to change.
Build one helper in packages/business/src, for example library-seats.mjs, exported from the package
index. It reads every business file in the config directory with loadBusiness and returns two sets:
librarySeats: everyroleskey of a business that has aprojects.<id>.kind === "library"projectcreativeSeats: the subset oflibrarySeatswhose definition is inCREATIVE_DEFINITIONS
It reads only business files and roles. Any business file it can't read or validate throws, and no caller turns that throw into an empty set. A seat name that appears in two businesses counts if either business puts it in a set.
- M7: the control board passes
isCreative = (root) => creativeSeats.has(root.seat)tocreateReader. It computes the sets on eachcatalogue()andopen(), not once at start, because the business file can change while the board runs. When the helper throws,catalogue()andopen()refuse withconversation-business-unreadable. They don't list everything, and they don't silently list nothing. - M8:
discord checkanddiscord runbuild the sets from the config directory their--configalready names. A binding whoseseatis inlibrarySeatsrefusesdiscord-engine-not-allowedunless its engine ismosaic-buswith notools. When the helper throws, both verbs refuse withdiscord-business-unreadable. A pi binding whose seat is in no library business checks clean, which is the brief's last test.
Your reading of the session paths is right. Creative thread sessions live at
<dataRoot>/threads/<business>/<thread>/session, outside every .pi/state root the board scans today, so
M7 is a second wall. Write that in the manifest notes. Add one test where a root spec points at a
creative seat's thread store and the root is hidden.
Scope amendment. The row adds these files: packages/business/src/library-seats.mjs (or the name you
pick), its export line in packages/business/src/index.mjs, a test in packages/business/tests,
packages/control-board/src/serve.mjs (the predicate wiring and REFUSAL_STATUS only), and a test in
packages/control-board/tests. packages/discord/src/binding.mjs stays untouched. The gate adds the
business and control-board suites, run whole, to the conversation and discord suites, plus every
scripts/test-*.sh.
Question 2: the refusal code for a mosaic-bus binding with tools
Reuse discord-engine-not-allowed, with a message that names the tools key. Approved as proposed.
Question 3: reconcile on conversation-not-listed
false: confirmed. reconcile: true on unknown-conversation and incomplete-header means a fresh read
may answer differently. A hidden root gives the same answer on every read until a human edits the
business file.
Question 4: HTTP status for conversation-not-listed
404, next to unknown-conversation: approved. conversation-business-unreadable gets 503. Both entries
go in REFUSAL_STATUS, which ruling 1 put in scope.
Other points
- The control-board serve test: keep it in phase B, run whole.
- New codes approved here:
conversation-business-unreadableanddiscord-business-unreadable. Nothing else is new. - The phase A commit 3fa833715 stays on
researcher/row220. The next round goes on a new branch name,researcher/row220-r2. Phase B runs only on my "slot clear".
