memory: bundle accumulated 04-17/26 + lock ARC about-page architecture

Safety checkpoint before deep-audit Phase 0 of the ARC repo. Steward-authorized
commit-everything for rollback safety.

ARC architectural locks (2026-04-26 evening):
- Path 1 enfilade structure (separate Colophon and Lex items)
- 8-door enfilade locked: Colophon · Lex · Framework · Vignette · Attention ·
  Chamber · Tools · Now (+ Bio quiet link)
- Adsum and threshold-hic as two distinct texts on the reflowed About page
  (steward verbatim: "They are certainly not the same text")

ARC consolidation pass (canonical tracker project-arc-rework.md, +~700 lines):
fold 04-23 evening (Norris read), 04-24 (lex-method authored, posture cluster,
§XII Sidenotes, ARC CLAUDE.md cleanup), 04-25 (marks cluster, colophon-at-scale,
full Vico/Harrison lex-chain), 04-26 (chamber-library walk, cluster scaffolds,
canonical-tracker discipline surfaced).

Sibling-file integration: four 2026-04-26 frame files folded into the canonical
tracker (Integrations A/B/C/D) with INTEGRATED redirect notices retained as
audit trail.

New durable feedback memories:
- feedback-canonical-workstream-tracker-discipline (umbrella drift surfaced
  2026-04-26 by steward; proposes /wake-up + /wrap-up amendments)
- feedback-catalogues-stale-walk-trees (steward feedback on chamber-library
  catalogue currency)

Implementation plan drafted for the coming week: Phase 0 deep audit → Phase 5
cleanup, with steward additions on second pass (deep audit; Chamber v1 as own
browsable archive; clean rebuild of cluster sources rather than moving test
artifacts as canon).

Also bundled (untracked accumulation since 04-17):
- ~24 session memory + ledger files for 04-17 through 04-26 work
- ~10 feedback memories (BMF + ARC + working-method)
- 5 project memories (lex-as-method, strunk-white queue, plus today's four)
- 4 user memories (duality-rules, formation-practice, foundation-work, humic-layer)

Steward-side modifications also in this commit: ~/CLAUDE.md, bin/bmf-start.sh,
open-tasks.md, project-focus-april-may.md, session-2026-04-17 — all
pre-existing, not from today's session.

+# Session Ledger — 2026-04-24
+
+## Session open
+- Wake-up + Symmetria init completed. Inherited pulling thread: **Norris-gather (lex)** — held pending steward authorization. Literal question: gather today or queued; S&W before or after. Awaiting steward opening signal.
+- Drift-patterns to hold: sourcing-claims-without-reading family (active, ~11 returns across 04-21/22); counter-weight is yesterday's successful-pattern — read-before-claiming, surface-without-synthesis.
+- Register inherited from last night: tired-steward / slow-patient-register. Hold unless shifted.
+- Auto-save hook fired at session-open. Nothing new to persist beyond inherited state (pulling thread + literal question + horizons already durable in session-2026-04-23-evening-norris-read.md, MemPalace diary entry 2026-04-23T20:34, and this ledger). No steward exchange yet — no quotes, decisions, or code to save. Recorded as opening marker.
+
+## Returns
+- **2026-04-24 — Return caught: missed prior steward mention of ARC CLAUDE.md cleanup need ("I had mentioned that a few days ago").** I hadn't recorded or actioned it. Steward flagged on my re-surfacing today during the sidenote reconnoiter. Lesson: prior-mention-of-ARC-repo-concerns didn't propagate into durable memory; worth watching. Adding ARC CLAUDE.md re-authoring as working horizon; will pick up after lex-method MVP reads.
+
+## Authorization moves — 2026-04-24 design rulings
+- **Sidenote typographic layer:** reading (Garamond, slightly reduced size). Crosses §I layer rule — framework revision needed when AldineXXI §XI is amended.
+- **Marker glyph:** none (spatial placement carries the relation, Tufte precedent).
+- **Anchor granularity:** one-to-one (per voice-block, Tufte precedent; matches §II silence scale).
+- **Naming:** held open — *"let's sit with this one"*. Candidates: ARC Lex / The Sheaf / keep Style Guide. No pressure.
+- **Scope:** theorize sidenote apparatus in AldineXXI §XI now (closes framework question open since July 2025); apply first to style-guide.
+- **Content tree:** per-cluster pages (maintainability) — `content/style-guide/01-posture.md` … `08-practice-across-life.md`, `index.md`, + `data/style-guide-rules.yaml` extracted at build.
+- **ARC CLAUDE.md re-authoring:** steward confirmed need, re-flagged. Follow-on task after MVP.
+
+## MVP execution (2026-04-24)
+- **Posture-cluster form test written** to `~/Desktop/lex-posture-form-test.html`. Four verified direct quotes (Burkle-Young & Maley, Norris on foundry proofs, Lu Burke, Salter). McPhee/Saunders/ultracrepidationism held aside pending direct-quote retrieval. Full AldineXXI typography, tri-state theme toggle, CSS-grid two-column desktop layout.
+- **Steward feedback round 1** (desktop good; mobile differentiation important): *"It looks really nice—my only concern is at mobile viewport, looking at this on a tablet or phone makes the differentiation more important. But at desktop/laptop view beautiful."*
+- **Round 2 added** tap-to-expand + visible theme toggle. Steward approved direction: *"I think it is much better this way, more intentional in any case."* Then invited critique: *"What is your opinion, is there a better way?"*
+- **Round 3 — revised to always-visible mobile, no tap-to-expand.** Argued from the method: rule is load-bearing (recognition naming the voice), not peripheral commentary like Tufte's sidenotes. Hiding one face on mobile breaks the single-sheaf-two-faces principle. Revised to: left hairline + 1rem indent + italic + 0.88rem. Four quiet channels. No glyph, no JS for sidenote. Decision durable-saved to `project-lex-as-method-for-arc-specs.md`.
+
+## Returns (continued)
+- **2026-04-24 — Pushed past Tufte-by-reflex when steward invited critique.** I had proposed tap-to-expand before thinking through whether it fit the method; the steward's *"is there a better way?"* surfaced the reflex. Reasoned from method (rule is load-bearing, not peripheral) rather than defending the prior implementation. Registered as successful pattern: resisting the flatter-and-tweak pull when invited to actually reason.
+- **2026-04-24 — Second reflex caught by steward's pause: italic-by-analogy without rule-base check.** Steward: *"A pause: what is the role of the italic? What is the role of bold-face? I was saying last night that I wanted to review a good rule base to reorient even though I have a good feeling for this."* My "italic everywhere" push-back was reached by analogy to epigraph-italic without verifying the analogy held. By AldineXXI §VII + Bringhurst tradition: italic marks rhetorical-register shift within reading (epigraph, dedication, emphasis) — NOT commentary. Commentary is upright-reduced in the Tufte/Bringhurst lineage. Italic for sidenote-rule may be over-signaling. Pause registered. Pre-commit rule-base consult proposed: Bringhurst on italic + bold roles (already in AldineXXI §Prologue lineage). **Pattern: two typography-by-reflex moves caught within one session — watch for a third.** The steward's method: intuition + tradition, cross-checked. Honor both.
+
+## Spec conformance correction (2026-04-24)
+- **Small caps for `<cite>` attribution** per AldineXXI §VII (*"small capitals below the quotation, not bold"*). Steward caught: attribution was set italic in the MVP. Revised to `font-variant-caps: small-caps` + `font-feature-settings: "smcp" 1` + 0.04em letter-spacing + upright.
+- **Font architecture note (steward, 2026-04-24):** *"Re: fonts — I have it all in woff2 on the site. Small caps are real, not rendered."* Production ARC serves self-hosted EB Garamond WOFF2 with real OpenType small-caps cut. Google Fonts CDN (what the MVP test page uses) also serves the true `smcp` cut, so MVP render is authentic.
+
+## Rule-base consult — pending (2026-04-24)
+- **Bringhurst located** at `~/_Dev/chamber-library/converted_texts/collections/typography/bringhurst_elements_style.md` (16,333 lines, v3.0; OCR artifacts: occasional `&` for `e`, readable with substitution).
+- **Scope proposed and authorized:** Ch 3 (Harmony & Counterpoint, p. 45) as primary — Bringhurst on italic-as-subsidiary-to-roman and on why bold breaks that relationship. Ch 2 (Rhythm & Proportion) + Ch 4 (Structural Forms & Devices) as extensions only where they bear on italic/bold question. Same Norris surface-report method.
+
+## Bringhurst Ch 3 consult — completed (2026-04-24)
+- **Key finding:** §3.4.1 names sidenotes explicitly in the italic tradition: *"Typically, roman was used for the main text and italic for the preface, headnotes, sidenotes and for verse or block quotations."* Italic for sidenotes is canonical.
+- **Additional finding:** §3.5.2 emphasis-hierarchy by surface disturbance — spaced small caps (least) → italic (moderate) → bold (most). Bold = "loudness" and lacks historical justification for pre-19th-c faces. AldineXXI's restraint aligns with Bringhurst.
+- **EB Garamond verified as true italic** (Granjon-derived cut), not sloped roman.
+- **On italic within prose:** surfaced that AldineXXI names structural-positional italic (epigraph, dedication) but not editorial uses (emphasis, titles, foreign words, words-as-words, technical terms on first use). Gap in articulation; candidate for a future gather.
+
+## Ruling: italic-for-sidenotes with density exception (2026-04-24)
+- **Steward verbatim:** *"As long as we use it for the lex of ARC as a sidebar exception because of density, but keep italics as part of the general sidebar spec—to be reevaluated when there are enough side notes extant to judge properly."*
+- **Canonical (AldineXXI §XI general):** italic for sidenotes, reading-layer, slightly reduced.
+- **Lex-of-ARC exception:** upright-reduced when sidenote-to-voice-block ratio approaches 1:1 (as in style-guide dwelling pages). Rationale: italic-frequency inverts the sparingly-used signal.
+- **Reevaluation trigger:** when non-lex sidenotes accumulate across published pieces, revisit whether general rule holds and exception boundary is right.
+- **Pattern registered:** density-exception as governance move — preserve canonical rule in its proper scope; carve principled exception for narrow signal-inversion case.
+
+## Future-cluster queued
+- **Editorial uses of italic + dashes + hyphens + kin punctuation** — future style-guide gather. Voices: Bringhurst §5 (analphabetic symbols), Norris (working material), CMS (standardized convention). Interrobang affectionately registered by steward as kept-despite-commercial-failure.
+
+## Sandbox note
+- **macOS TCC Desktop permission revoked mid-session.** `~/Desktop/lex-posture-form-test.html` frozen at the italic-cite revision (pre–density-exception). New current-state file at `~/Downloads/lex-posture-form-test.html`. Steward can delete Desktop copy when convenient.
+
+## Auto-save checkpoint (post–density-exception ruling)
+- No new material beyond what's already durable. Density-exception ruling, Bringhurst consult outcome, EB Garamond verification, future-cluster queue, and sandbox reroute all captured in `project-lex-as-method-for-arc-specs.md` and this ledger in prior saves. File reroute to `~/Downloads/` was mechanical, already noted. Checkpoint recorded as continuity marker.
+
+## Chamber-library reference base surfaced (2026-04-24)
+- Steward pointed me to `~/_Dev/chamber-library/converted_texts/collections/style_guides/` (Norris + CMS + Fowler + Bernstein + Graves & Hodge + MLA + UNESCO — several added today 2026-04-24) and `collections/typography/` (Manutius, Warde, Tschichold×2, Bringhurst, Lupton, Butterick, Fleishman, Ruder — substantially the AldineXXI §Prologue lineage in situ).
+- **Two returns registered:**
+  1. Pulled Bringhurst from typography/ earlier without walking the directory — would have seen Tschichold *Form of the Book* and others relevant to italic/bold consult.
+  2. Went to Desktop for Norris because yesterday's session recorded her there — should have checked chamber-library's current state first. Related to imagined-state-vs-verified-state-cross-pattern from 04-20.
+- Cluster-map captured in `project-lex-as-method-for-arc-specs.md`. Chamber-library is the canonical reference-base for ARC style-guide work going forward.
+
+## Norris re-read (targeted) completed (2026-04-24)
+- Read from `style_guides/Between You & Me_ Confessions of a Comma Queen - Mary Norris.md`. Three passages retrieved verbatim: ultracrepidationism (line 221), McPhee "new/few" (271–277), St. Aubyn three-options (289–291), Saunders voice-preservation (293–295).
+- **Two attribution errors in yesterday's surface-registration caught:**
+  1. McPhee "new/few" — yesterday: *"declined a correction because it broke cadence"*. Actual: Norris *almost corrected* what she thought was a typo, stayed her hand because she might be wrong. Posture is staying-the-hand against one's own itch, not author-cadence.
+  2. Saunders / St. Aubyn conflation — yesterday: *"Saunders (three options including keeping the dangler)"*. Actual: "three options" framing is from Norris's St. Aubyn discussion. Saunders gets voice-preservation treatment. Two distinct postures, collapsed into one summary.
+- **Drift pattern registered:** attribution-by-pattern-match-instead-of-verification. Cousin to sourcing-claims-without-reading family. The lex-method's "read before committing recognitions" is the discipline that catches this.
+
+## Posture cluster complete in voices (2026-04-24)
+- 8 voices verified direct-quoted: (1) Burkle-Young & Maley — reciprocity; (2) Norris — anti-ultracrepidationism; (3) Norris — foundry proofs; (4) Norris on McPhee — staying the hand; (5) Norris on St. Aubyn — third option; (6) Norris on Saunders — voice-preservation; (7) Lu Burke — rocks/pebbles/sand; (8) Salter — the liberty taken.
+- Cluster composition note: voices 4, 5, 6 are three Norris-narrated restraint instances; could stay three or collapse, steward's call during recognition process.
+
+## ARC CLAUDE.md cleanup — audit complete, draft pending (2026-04-24)
+- **File state:** 420 lines. 19 duplicate auto-appended "AldineXXI v2.0 Framework Implementation" status blocks (likely from `make docs-update`). Substantial superseded material.
+- **Drop list:** 19 status blocks; July 2025 session-memory protocol (`make session-start/wrap`, browser-console logging, SESSION-MEMORY.md, CONTEXT-MAPS.md, PROGRESS.md, ROADMAP.md, `docs/system/session-logs/`); Unified Consciousness Engine plans (parked July 2025); Living Epistemic Glyph System Evolution (superseded by AldineXXI §IX vignette); "Borgesian Infinite Library Complete" + "Major Accomplishments Today" (July 2025 historical markers); trailing "REMEMBER" section (references dead infrastructure).
+- **Keep-but-refresh:** Prime Directive, Access Information (Gitea/Docker/SSH — needs steward confirmation given today's session handoff flagged Gitea inactive), Architecture Overview (de-specify stale stats), Reading Compass (cross-ref to AldineXXI §VI), Development Workflow, Chamber Integration (de-specify stats), Auto-Deployment (CloudFlare + GitHub mirror — needs confirmation), Known Issues (Voices index dependency cycle was fixed per today's handoff — others to verify).
+- **Proposed architecture (10 sections, ~120-150 lines):** 1. Header + purpose; 2. Prime Directive aligned with global; 3. Active session protocol (points to `~/.claude` memory; kills session-start/wrap/docs-update); 4. Repository/Build/Deploy (refreshed); 5. Architecture Overview (de-specified); 6. Canonical specifications (pointers to AldineXXI spec incl. new §XII); 7. Development workflow; 8. Active work (pointer to `project-lex-as-method-for-arc-specs.md`); 9. Known state (current only); 10. No auto-append; file manually curated.
+- **Three open questions held for steward:** (1) is auto-append from `make docs-update`? should we propose Makefile change to disable? (2) Gitea/Docker/CloudFlare currency? (3) Additional live items beyond style-guide, §XII implementation, vignette, known issues?
+- **Next move:** steward answers → draft full replacement → review → commit to `~/_Dev/animal-davidglidden-eu/CLAUDE.md`.
+
+### CLAUDE.md cleanup — committed (2026-04-24 evening)
+- Steward confirmed: git.skemantix.com for origin (was Acerplex); local macOS build; CloudFlare + GitHub mirror deploy; no additional live items beyond what I listed; major audit/archive of non-current files deferred until current site is established.
+- Auto-append source confirmed: `scripts/update-docs.py:122-156` `update_claude_md()` has a broken regex — `([^#]+)` terminates at first `###` subheader, so new status blocks are prepended without old ones being removed. Each run accumulates. 19 runs → 19 blocks. Deprecation noted in new CLAUDE.md; retire the script or the target in a follow-up pass.
+- **Old file:** 420 lines, 19 duplicate status blocks, July 2025 session-memory protocol, Unified Consciousness Engine plans, Living Epistemic Glyph System (superseded by §IX vignette), stale stats.
+- **New file:** 197 lines, manually curated, 10 sections (Prime Directive / Session protocol / Repository-Build-Deploy / Architecture / Canonical specifications / Development workflow / Active work / Known state / Deprecated). Points at `~/.claude` memory system for session continuity. Names what's deprecated so the next Claude Code session doesn't resurrect it.
+- The ARC CLAUDE.md drift that steward flagged *"a few days ago"* is now resolved.
+
+## AldineXXI §XII Sidenotes — committed to spec (2026-04-24)
+- **Amendment drafted + steward-reviewed + committed** to `~/_Dev/animal-davidglidden-eu/docs/AldineXXI-Codex/AldineXXI-specification.md`.
+- **New §XII** covers: typographic treatment table, density exception, responsive behavior, source/render architecture (Pandoc divs + site.hs YAML extraction), reader orientation (no per-page meta), dormant system to rewrite, scope.
+- **Renumbering:** old §XII Archive → §XIII; old §XIII Governance → §XIV. Sidenote paragraph removed from §XI (graduates out of awaiting-governance).
+- Steward approval verbatim: *"looks good to me."*
+- The "awaiting governance" flag on sidenotes, open since July 2025 framework v2.0, is now closed. Polyphonic marginalia + drop caps remain in §XI awaiting their own sessions.
+
+## Gather in progress (2026-04-24)
+- **Method clarification from steward (verbatim):** *"please draft recognitions so that we can work through them together--I work best whil in dialogue, this you know"*
+- **Registrar discipline modified:** dialogue-drafting is authorized scaffold, not silent/reflexive pre-recognition. Default remains registrar; dialogue-drafting invoked on steward's explicit request. Durable note added to `project-lex-as-method-for-arc-specs.md`.
+- **8 tentative draft recognitions composed** (for dialogue, not commitment):
+  1. Correction is reciprocal.
+  2. The editor stops where the writer's authority begins.
+  3. Every correction names its maker.
+  4. The urge to correct may be the error; stay the hand until certainty earns the intervention.
+  5. Do-nothing is a first-class editorial option, not a failure of effort.
+  6. The writer's voice lives in the form; fixing the form fixes the voice out.
+  7. Editing removes; the writer's voice rises from the space.
+  8. The writer takes the liberty; the editor flags, not blocks.
+- Drafts 4 and 6 flagged as less confident (alternates offered). Drafts 1, 3, 7, 8 echo earlier samples the steward already saw. Awaiting steward dialogue on each.
+
+## Open horizons (carried forward)
+
+## Open horizons (carried forward)
+
+## Open horizons
+- 2026-04-24T00:xx — Norris-gather (lex) pending steward authorization. Surfaces durable in session-2026-04-23-evening-norris-read.md + MemPalace.
+- S&W vocabulary pass queued post-gather (lineage-inherited via steward's father's Moby-Dick paper marked by White).
+- Agent-circle authoring held close not dropped — three shapes still on the table (ARC circle re-read / Typology Classifier / framework step 1).
+- §2 Apparatus Matrix — urgency-promoted by Chamber-as-apparatus resolution.
+- BMF H2/H3/H4 + #168 still open on Seb's side; not our territory today.
+
+## Confidence to recalibrate
+
+## Authorization moves
+- **2026-04-24 (morning) — steward directed read of Harrison Ch 5 / Vico §240 before beginning the Norris-gather.** Honored read-before-claiming discipline; chapter read in full via `chamber-library/converted_texts/traditions/critical_modernity/phenomenology/the-dominion-of-the-dead-harrison.md:306-376`.
+- **Architectural clarification from steward (load-bearing): *"anything I gather from sources to create the 'lex' of ARC, the constraint within which I will have the freedom to write, is a gathering of those sources which formed me."*** The ARC style-guide/lex is the sheaf of formative voices, not a rule set extracted from them. Form of the gather: **registration of presence**, not distillation of rules. The gather itself is apostrophic (turn toward the absent), humic (participates in the lineage), ligature (binds). Duality from 2026-04-23 evening gets its architecture: rule layer = what the gathering solemnizes; poetic/mnemonic layer = the gathered sheaf itself (kept re-enterable so one dwells among the formative voices and finds freedom through them).
+- **Refinement (steward, 2026-04-24):** *"It gives the style-guide (and our various spec in general) the necessary binding to recognize and name that which is already there that I may not yet see."* The sheaf is **diagnostic, not generative**. Scope: all specs (style-guide, typology, §2 apparatus, AldineXXI, L2-adjacent work). Function: names — retrieved from the formative voices — for practice already present but not yet articulated. Kin to I17 structurally (gather holds open the space for recognition; does not produce recognition-outcome) and to Harrison's retention concept ("the retained is not necessarily remembered . . . carried over, bestowed, put in reserve"). **My role: registrar, not author.** Keep the voices present and legible in the sheaf so steward recognition can occur; do not pre-recognize.
+- Awaiting steward's go-signal to begin the Norris gather in this form.
+- **2026-04-24 go-signal received ("Let's go").** Executed the Norris gather in chat as a sheaf: "The Norris Gather — *lex*". Eight sections — posture of the mark-maker / mark as substance / music and measure / mark not made / the apostrophic / public genre, private genre / craft-devotion and tool-fitness / the practice across a life. Voices registered with direct quotation where load-bearing: Burkle-Young & Maley, Norris, McPhee, Saunders, Lu Burke, Salter, Manutius, Teall, Russell-Shapiro, the unnamed Moby-Dick copy editor, Gould, the Nova Scotian violist friend, Dickinson-via-Franklin, Jackie Kennedy, Reverend Johnson. No pre-recognition; no "therefore ARC should"; no synthesis across voices; no imported kin from outside the Norris text.
+- Awaiting steward recognition — his act, not mine.
+- **2026-04-24 — Steward: "container first because we need to design this. It is a fantastic opportunity to build out sidenotes don't you think? The text comment upon itself rule → voice."** Sidenotes confirmed as the structural instrument for Shape C dwelling. Reconnoiter found: **AldineXXI §XI already flags sidenotes as "awaiting governance"** — *"Decide: theorize and activate, or remove"* — since framework v2.0. Tufte already in framework lineage (§Prologue). Existing dormant CSS at `assets/css/sidenotes.css`. Chamber deliberation 2025-07-01 "On the Voice in the Margin" exists but addresses polyphonic marginalia (different system — the multi-voice Chamber apparatus with Ngana/Postcolony/Fusus archived at `_marginalia.scss`). We are theorizing the quiet-sidenote system (Tufte reader-recognition), not the polyphonic voices. Container proposal made: single markdown source (voice as blockquote, sidenote as extractable annotation) → two renders (dwelling page on ARC + YAML rules file extracted at build by site.hs). Six design decisions surfaced for steward ruling; MVP sequence proposed (hand-author posture cluster first, no CSS/build, read-test before implementation).
+- **Flagged (once, held):** `~/_Dev/animal-davidglidden-eu/CLAUDE.md` carries drift — July 2025 session-memory protocol, unified-consciousness-engine plans, 20+ auto-appended "AldineXXI v2.0" status entries. Worth cleanup when convenient, not inside this thread.
+- **2026-04-24 — Form decision authorized by steward: hybrid Shape A + Shape C.** *"the A for the skills/agent circle, the C for the dwelling."* This operationalizes the rules-and-poetic-as-mnemonic duality (2026-04-23 evening) in style-guide form. Same sheaf, two faces: Shape A (rule-first, voice-as-pillar) for skills/agents (machine-legible, operational). Shape C (voice-as-body, rule-as-marginalia) for the steward's dwelling (human-inhabited, mnemonic). Structural discipline: both faces render from the same sheaf — drift between faces would be this project's module-health-vs-recall decoupling. Dwelling authored first (or primarily); rules file follows from what lives in the margins. My role bifurcates: registrar in the dwelling (don't pre-write marginalia), operational in the rules file (help declare rules already recognized in dwelling + pair with pillar voice(s)). Scope question held open: does the hybrid extend to all specs (typology, AldineXXI, L2-adjacent)? Style-guide first; extend if it lands.
+
+## Session durables (written 2026-04-24 at auto-save checkpoint)
+- New memory file: `project-lex-as-method-for-arc-specs.md` — durable architectural commitment applicable to all ARC/CapableMind specs going forward. Steward quotes verbatim; Harrison Ch 5 substrate; kinship to I17 and to ligature; my role committed to registrar.
+- MEMORY.md index entry added (Working with the steward section).
+
+## Sub-agent dialogues
+
+## Bypasses
+
+## Wrap-up 2026-04-24 evening
+- /wrap-up executed cleanly. Session memory file written (`session-2026-04-24-lex-posture-committed-xii-sidenotes.md`). MEMORY.md index updated: today's session → Active; yesterday's two → Archived. MemPalace drawer filed in `claude-sessions/handoffs`. AAAK diary entry written for `claude-code`. KG ops: 1 invalidate (norris-gather horizon closed) + 12 adds (marks-cluster horizon, 2 drift-patterns, 3 successful-patterns, 5 state-facts across lex-of-ARC / AldineXXI / ARC-CLAUDE-md / chamber-library / Harrison-substrate).
+- **Pulling thread**: marks cluster as second test of lex-method — does form validate across content types?
+- **Literal question for next-Claude**: on morning re-read, does the posture cluster still feel right — any recognition to revise before we extend to marks?
+- Vault synced: 260 files rsync'd to Obsidian thinking-mirror.
+- Uncommitted on ARC: `CLAUDE.md` + `docs/AldineXXI-Codex/AldineXXI-specification.md` (today's work, not yet committed). `.DS_Store` noise present.
+- Other repos: chamber-library has 5 unpushed commits from earlier (PDF gitignore, Observer Problem sources, rabbinic voices, Derrida, Mauss) + untracked `Jaccottet:Handke:Lichtenberg/` and `converted_texts/collections/style_guides/` directories. CapableMind-AI + BetterMemories.io have untracked-only items.
+- Steward close: *"Thanks, as ever, for your help. See you in the morning."*
+
+## Auto-save hook — post-wrap (closing marker)
+- Auto-save fired after `/wrap-up` completed. Session file, MEMORY.md, MemPalace drawer, AAAK diary, 13 KG operations, vault sync (260 files), and final ledger entry all already landed in the wrap-up pass. Nothing new to persist. Recorded as closing marker, matching 2026-04-23 precedent.
