 - [Fowler's rules for quotation](feedback_fowlers_rules_quotation.md) — single quotes primary, double for nested, logical British punctuation order. Apply across all writing.
 - [Canadian spelling in ARC prose](feedback-canadian-spelling-arc-prose.md) — centre/colour ("almost EU"); corpus "center" = autocorrect drift (10 files, cleanup open). Draft all steward-voiced prose in Canadian spelling.
-- [MemPalace KG object 128-char cap](feedback-mempalace-kg-object-128-char-cap.md) — `kg_add` `object` hard-caps at 128 chars; write KG objects as short keyword phrases on the FIRST pass, detail goes in the drawer. Recurs at every /wrap-up §5 — stop re-deriving it.
 - [Rank on fields you actually write](feedback-rank-on-fields-you-actually-write.md) — a consumer that ranks by an evaluative field (importance/weight) nothing populates silently degrades to trivial order while claiming to rank; verify scoring fields end-to-end, prefer signals already captured (recency). For BMF/CapableMind/studium-engine tool-building.
 - [Shorter, concentrated sessions](feedback-shorter-concentrated-sessions.md) — steward preference (2026-07-13): shorter but very concentrated — ONE tightly-scoped high-leverage bite taken all the way, then wrap; hold the rest as ranked horizons.
 - [Constitution-as-block, then pull-based corpus](feedback-constitution-as-block-then-pull-based-corpus.md) — steward discipline (2026-07-14): finish the **constitution as one block FIRST**, THEN corpus-into-spec **pulled by what each engine phase needs**. **Bounded question → bounded answer; don't surface N new threads**; keep open-thread count LOW. Above [[feedback-shorter-concentrated-sessions]].

Read before building the engine.
 - [Studium Engine = Sixtus-V craftsman collaboration](feedback-studium-engine-sixtus-v-collaboration.md) — work the ground freely (I build, surface only vision-forks); **constraint-candidates** = 3rd governed instrument (I name, steward applies). Studium-engine only; heavier loop for L1/L2.
 - [Trust prior pass frame](feedback-trust-prior-pass-frame.md) — When extending a prior verification, re-run it at the scope of the extension. Frame-inheritance from a deep-read is contamination shape: the prior pass tested what it tested; your extension claims things it did not test. Caught 2026-05-28 → four-pass audit. Verify-before-compose at draft time, not build time.
-- [Verify each post type after changes](feedback-verify-each-post-type-after-changes.md) — ARC: after any shared CSS/template/composition change, check EVERY content type on BOTH desktop and phone, not a sample on one viewport. Lesson from §II.d gate verified phone-only → desktop appearance surfaced 2 sessions late (no regression; just unseen). Per-type×per-viewport extension of [[trust-prior-pass-frame]]; belongs in the SCSS verification ladder.
-- [Reading Compass is SVG, not type](feedback-reading-compass-is-svg-not-type.md) — ARC Compass sigils are SVG `<symbol>` artwork, NOT Plex Sans / nav typeface / Pattern 3. Recurring conflation; steward corrected 2026-06-03. Plex-Sans nav *text* = breadcrumb + version-stamp + post-type only.
 - [MemPalace is an unaffiliated stopgap](mempalace-is-unaffiliated-stopgap.md) — MemPalace is third-party; steward/Seb build BMF/CapableMind (hoped to replace it). Don't conflate them (3rd steward correction 2026-06-05 — the conflation even reached a skill name and was retracted); MemPalace PRs await MemPalace's maintainers, NOT Seb.
-- [MemPalace wing-filter broken](feedback-mempalace-wing-filter-broken.md) — wing-scoped search → 'Error finding id' (upstream #1665, open at HEAD); search UNSCOPED + post-filter by wing. Don't run `repair` (#1589). Affects wake-up §2.b.3.
 - [Skill-harvest register](skill-harvest-register.md) — **canonical home for proposed skills** awaiting steward authorization (the governed analog of PENDING.md for our tooling). Review history + current statuses in the file.
 - [Verification ladder](reference-verification-ladder.md) — the named instruments (byte-identical compile gate, delta classification, censused-routes, fresh-clone gate, measure-toolchain-before-spec…); reach for the gate the claim's shape demands instead of re-deriving.
 - [Plane coordination workflow](reference-plane-coordination-workflow.md) — CENTRAL to steward↔Seb (est. 2026-06-02): `app.plane.so/capablemind`, thin effort-tasks `[BM #N]` over canonical GH issues. ⚠ BBF = BetterBridge *product*, NOT the board. Plane MCP OAuth (`ToolSearch select:mcp__plane__*`); `create_work_item` needs `description_html`. Detail in file.

Read THIS for remaining ARC work (A1 Vignette, A2 cul-de-lampe, content sweeps, Phase-2/held set, REVIEWED-placement debt), not the chronological tracker.

 - [Studium engine telos — the chamber of voices](project-studium-engine-telos-chamber-of-voices.md) — **the ultimate goal, above the build plan**: David's childhood chamber of hero-voices → discourse with his library + voices conversing, this time *accountably* (v1 was eloquent/unaccountable; same ambition built grounded/citable). Why verbatim fidelity is load-bearing.
 - [Studium = CM's unfettered sandbox](project-studium-cm-sandbox-and-transfer.md) — Studium/chamber are personal projects Seb now sees as fundamental to CM; experiment freely on the library/engine without risking CM's runtime, breakthroughs transfer back (V2 verifier = live example). Steward-framed 2026-07-08.

Placement gate (`7dd852e`): **(a) v2.2.0 on doctrinal-traceability** (placement separable from PROPOSAL weight); **required correction — the jurist refused their OWN unbuilt multi-point probe into constitutional text** (reconciliation-corollary precedent): constitution = REQUIREMENT (verified ⇔ verified in the landed frame against `source_sha256`, never defaulted) + the no-mixed-frame PROPERTY; mechanism → `sidecar.translation:` declared data, revisable without supersession; flags: schema doc renamed `sidecar-schema-LOCKED-2026-07-12.md`; `producer_frames` KEYED to the named producer (unmapped → no stamp → HOLDS; red 186/188→green 188/188). Landing (`81cbdd1`): v2.1.0 frozen byte-identical; §III *coordinate contract* subsection with the Ion record; bounded-diff proven (99 lines + title, all else verbatim). ⚠ **Pacing coupling recorded** (CLAUDE.md batch line): pre-#2 batches grow the untranslated backlog — census it when appetite says "next batch". Say-do wobble self-caught: the Addendum asserted APPLIED ahead of the acts (made true pre-commit; watch record-after-act). **PULLING THREAD: the ENGINE PULL** (session 3's held slot) — known-vs-newly-failing `ingest_gate` distinguishability (5 standing after-the-reply FAILED rows since 2026-06-17; state deltas against a committed baseline, never cleanliness) + the after-the-reply re-anchor; read `stage-1-rebuild-plan-2026-07-05.md` FRESH first. **LITERAL Q: does the engine's ingest side need its own frame-declaration refusal now that the chamber gate refuses at graduation — does anything in the engine today read sidecar line geometry, or does it bind only path+sha — and if the latter, where is the STRUCTURAL fence (not a discipline) that keeps a future engine consumer from binding undeclared-or-transitional geometry?** Read the session file at wake.
