+# Imaginary stack Step 1 — formalize 4D cube and imaginary intersection
+
+## Parent
+
+B-0543 (Remember-When + Pay-Attention → QG isomorphism proof path)
+
+## Why
+
+B-0543 Step 2 requires showing that the infinite-game extension produces a structure isomorphic (or homomorphic) to a HaPPY-like quantum error-correcting code. The "cube + imaginary intersection + Adinkra + Cayley-Dickson" framing is currently intuitive. This row decomposes the first concrete formalization step.
+
+## Goal
+
+Produce a small, hand-off-able formal object (category, algebra, or topos fragment) that captures:
+
+- The 4D real cube with axes Remember (R), When (W), Pay (P), Attention (A)
+- The imaginary directions generated at the intersections of these axes
+- The first Cayley-Dickson doubling(s) that produce the "imaginary stack"
+
+This object should be small enough that a category theorist or proof engineer can continue from it.
+
+## Acceptance criteria
+
+- [ ] A 4D real vector space or module with coordinates (R, W, P, A) is defined
+- [ ] Imaginary units \( i_{XY} \) for selected pairs of axes are introduced with \( i_{XY}^2 = -1 \)
+- [ ] At least one Cayley-Dickson doubling is performed explicitly
+- [ ] The resulting algebra is shown to have (or is conjectured to have) a natural error-correcting or reconstruction property
+- [ ] The definition is written in a form usable by Lean 4, Z3, or a category-theory paper (not just prose)
+
+## Non-goals
+
+- Proving the full HaPPY isomorphism (that's B-0543 Step 2)
+- Adding the Adinkra layer (that can be a follow-on row)
+- Predicting new physics (B-0543 Step 4)
+
+## Composes with
+
+- B-0543 (parent proof strategy)
+- `docs/research/2026-05-16-imaginary-stack-cube-axes-intersection-formalization.md` (the note that motivated this row)
+
+## Status
+
+Open. High-value decomposition of B-0543. Ready for a category-theory or algebra specialist (or a proof-engineer agent) to pick up.

+## Step 2 — Holding-discipline triage
+
+Per [`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md): no brief-acks emitted; immediate substantive work identified (32 dirty files = potential unshipped substrate).

+
+Applied [`backlog-item-start-gate.md`](../../../../../../.claude/rules/backlog-item-start-gate.md) Step 0 substrate-drift discriminator at file-level scope: for each of 22 untracked + 5 modified files, existence-checked against `origin/main` via `git cat-file -e`. Result:

+Selected the Imaginary Stack cluster — highest substrate value, atomic, composes with existing work without conflict.

+## Step 4 — Verify + commit
+
+Borrow-on-existing pattern executed in primary worktree:

+2. `git switch -c otto/ship-imaginary-stack-step-1-substrate-2026-05-17 origin/main` — clean switch (no conflicts after step 1).
+3. Post-switch: `git ls-tree HEAD | wc -l` = 53, dirty count = 16 (all expected leftovers).
+4. `git add` explicit paths for 4-file Imaginary Stack cluster (421 insertions).
+5. `git branch --show-current` verified pre-commit per [`zeta-expected-branch.md`](../../../../../../.claude/rules/zeta-expected-branch.md) primary defense.

+7. `git push -u origin <branch>` clean.
+8. `gh pr create --head <branch> --base main` per [`zeta-expected-branch.md`](../../../../../../.claude/rules/zeta-expected-branch.md) companion-defense — opened [PR #4059](https://github.com/Lucent-Financial-Group/Zeta/pull/4059).

+
+## Substrate-honest deferrals (future ticks)
+
+- `bun.lock` + `package.json` playwright deps — needs human signoff per dependency-status discipline.
+- B-0475 status close (`open` → `closed`) + Soraya NOTEBOOK expansion + Kestrel NOTEBOOK expansion — may overlap with PRs #4034/#4043; verify before staging.

+## Step 2 — Holding-discipline triage
+
+No brief-acks emitted. Substantive work selected immediately based on PR #4059 (shipped 1019Z) showing 3 CI failures.
+
+## Step 3 — Pick work
+
+Per [`blocked-green-ci-investigate-threads.md`](../../../../../../.claude/rules/blocked-green-ci-investigate-threads.md): PR #4059 surfaced 3 mechanical failures + 12 IN_PROGRESS at 10:25Z first-poll:
+
+1. `check docs/BACKLOG.md generated-index drift` — B-0584 row required `BACKLOG_WRITE_FORCE=1 bun tools/backlog/generate-index.ts` regen
+2. `lint (tick-shard relative-paths)` — 1019Z.md used 5 `../` for `.claude/rules/<x>.md`; correct depth is 6 (verified against reference 0418Z.md)
+3. `lint (markdownlint)` MD047 — B-0584 row missing trailing newline
+
+All three: mechanizable in this tick. Picked.
+
+## Step 4 — Verify + commit
+
+Operations performed:
+
+1. `BACKLOG_WRITE_FORCE=1 bun tools/backlog/generate-index.ts` → wrote docs/BACKLOG.md (B-0584 + composite-index updates)
+2. `bun tools/hygiene/audit-tick-shard-relative-paths.ts` → identified 10 broken links in 1019Z.md (5-vs-6 `../` depth bug)
+3. Edit tool with `replace_all=true`: replace 5-dot prefix with 6-dot prefix for all `.claude/rules/` links in 1019Z.md (depth fix; 5 `..` lands at `docs/`, 6 `..` lands at repo root).
+4. Post-fix audit: 10 broken links REMAINING are pre-existing baseline entries in older shards (2026-04-29, 2026-05-14/15) — not regressions; my contributions ZERO
+5. `bunx markdownlint-cli2` on 5 files (B-0584 + 2 research + 1019Z.md + regenerated BACKLOG.md) → only B-0584 missing MD047 trailing newline; fixed
+6. Verify branch via `git branch --show-current` before commit

+

+
+## Step 6 — Cron sentinel
+
+CronCreate `9e8944ea` armed at 1010Z session start (catch-43 compliance). Re-verify post-shard.
+
+## Step 7 — Visibility signal
+
+Concrete artifacts landed this tick:

+
+## Pure-git tier note
+

Per [`refresh-world-model-poll-pr-gate.md`](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md), pure-git tier permits: `git fetch` / `git push` / `git log` / `git show`, deferred PR-state queries to post-reset tick.
