Pull request overview
Adds the missing “Imaginary Stack” Step-1 research substrate for B-0584/B-0543, including two research notes and a Lean 4 toy-model scaffold intended for future formal verification work.
Changes:
- Adds a new P2 backlog row (B-0584) defining Step-1 scope and acceptance criteria.
- Adds two
docs/research/notes formalizing the 4D cube + imaginary-doubling framing and a toy “Lemma 1” statement. - Adds a Lean 4 toy-model file intended to encode the toy lemma structure.

Replaced 5 `../` with 6 throughout 1019Z.md. Post-fix audit: 10 broken links remaining are all pre-existing baseline entries in older shards (2026-04-29, 2026-05-14/15) — not regressions. 3. `lint (markdownlint)` — B-0584 row missing MD047 single-trailing- newline.

CI generator (running on committed state with status: open) produced `[ ]`, mismatched BACKLOG.md `[x]`. Fix: revert BACKLOG.md line 282 from `[x]` to `[ ]` to match committed B-0475 status. B-0475 close stays in working tree for a dedicated future PR with substrate-honest scope. 2. `lint (semgrep)` `invisible-unicode-in-text` — 1034Z.md line 41 contained U+200B (zero-width space) from prior-tool typography that displayed `5 ../` vs `6 ../` distinctly. The hidden character triggered the steganography-detection rule (correctly — exactly what `prompt-protector` lineage was built to catch). Rephrased the line in plain text; no zero-width characters. Local verification: - `git stash` B-0475 working-tree mod, `--check` passes, `git stash pop` - python3 scan of 1034Z.md for U+200B/200C/200D/2060/FEFF/2066-2069 → 0 Co-Authored-By: Claude <noreply@anthropic.com>

…hread Reviewer (Copilot P1) flagged docs/research/.../lemma-1.md L89 mixing an ℝ-based norm inequality with the ZMod 17 instantiation in the Lean file. The substrate-honest fix is default-to-both: make the two layers explicit so a proof engineer can pick the relevant version. Added a "Note on field choice (ℝ vs ZMod 17)" paragraph after the lemma statement: - ℝ-valued lemma is the structural claim — orthonormal basis + ‖·‖ norm well-defined. - ZMod 17 instantiation in tools/lean4/ImaginaryStack/ToyModel.lean is for enumerability + exact arithmetic; ε = 0 + Hamming distance replaces the ambient norm. Both are intended; this PR makes the bothness discoverable on the research surface where a reader actually lands. Composes with B-0612 (Lean rewrite under Soraya's lane) — the Lean file will adopt the ZMod-17-with-Hamming framing explicitly when it gets the structural rewrite.

…3 link Two reviewer findings (Codex P2 + Codex P2) addressed substrate-side: 1. memory/MEMORY.md L22/23/37 had 3 entries pointing to files not in this branch's HEAD tree (Kestrel + Riven conversations + Otto cwd-fix memo are working-tree-only / on other PRs). Reindexer is fs-walk- based (not git-aware), so untracked files leaked into MEMORY.md during prior regen. Surgical removal of the 3 dangling entries (lines for the 3 specific files). The files arrive on main via their dedicated PRs; future reindex will re-add the entries when the files reach main via merge. 2. docs/backlog/P2/B-0612-... L20 B-0543 parent link pointed to docs/backlog/P1/B-0543-remember-when-plus-pay-attention-yields- qg-isomorphism-2026-05-15.md (wrong path AND wrong filename). Actual file: docs/backlog/P2/B-0543-qg-isomorphism-proof-path- remember-when-pay-attention-axioms-to-quantum-gravity-2026-05-15.md. Link corrected to sibling-relative form.

…consistency Reviewer P0 catch on docs/BACKLOG.md:282 was correct: peer-Otto's 31103de regenerated BACKLOG.md with B-0475 as [x] (closed) by running BACKLOG_WRITE_FORCE=1 generate-index.ts; the generator read the working-tree-modified row file (status: closed already on disk, acceptance bullets [x]) but only the BACKLOG.md output got committed in 31103de. The row file's changes were never committed, so HEAD's row file still said status: open. Next generate-index.ts run would have reverted BACKLOG.md back to [ ], creating a regen-loop. This commit makes the substrate self-consistent: status: open → status: closed; the three acceptance bullets [ ] → [x] for prior-art search, parent-chain walk, and reciprocal composes_with backfill. Substrate-honest provenance disclosure: the working-tree edit predates my session (Aaron-or-prior-peer-Otto authored it locally, never committed). I'm landing it now because the inconsistency is P0 and peer-Otto already committed BACKLOG.md's [x] half — the fix has to land somewhere; committing the row to match is substrate-truer than reverting BACKLOG.md to [ ] would be (acceptance bullets confirm 3-of-3 done; the gen-index outcome confirms it from the other direction).

…e gap (PR #4059 two threads) Two reviewer threads addressed substrate-honestly on memory/feedback_git_worktree_corruption_*.md: L26 (P1 overclaim): Previous wording said "Lior's launchd runner (.plist) and tick prompt (.ts) have been updated." Reviewer correctly noted this PR only changed .gemini/bin/lior-loop-tick.ts (verified: 6d30969's diff touches only the .ts file; plist is unchanged). Rewrote line 26 to make clear that the prompt was updated and the plist is mentioned as context (the runner that invokes the prompt), not as something this PR modified. L27 (lockfile-probe robustness): Reviewer flagged that `ls .git/worktrees/*/lock` with a non-matching glob exits non-zero on most healthy systems, which could read as "lock present" false-positive. Rewrote line 27 to (a) name this as "high-level intent" rather than the exact substrate, (b) explicitly acknowledge the brittleness with the literal `ls` glob, (c) point at the hardening path (compgen -G or shopt nullglob) for the next iteration of the tick prompt. The actual lior-loop-tick.ts hardening is deferred until Lior is quiet enough to safely modify the running loop's prompt file. Composes with d902f25 (prior xref-paths fix to same memo) and with 8e1b54c (this tick's B-0475 P0 inconsistency fix). Co-Authored-By: Claude <noreply@anthropic.com>

| `tools/lean4/ImaginaryStack/ToyModel.lean` shipped via PR [#4059](https://github.com/Lucent-Financial-Group/Zeta/pull/4059) as research-grade substrate cherry-picked from Riven's Cursor-Lean4 sketch (per `memory/persona/riven/conversations/2026-05-17-riven-aaron-cursor-lean4-sketch-handoff-to-soraya-b0543-qg-isomorphism-proof-path.md`). Reviewer triage in tick shard [`docs/hygiene-history/ticks/2026/05/17/1218Z.md`](../../hygiene-history/ticks/2026/05/17/1218Z.md) verified three structural P0/P1 findings: |
There was a problem hiding this comment.
The Why paragraph cites memory/persona/riven/conversations/2026-05-17-riven-aaron-cursor-lean4-sketch-handoff-to-soraya-b0543-qg-isomorphism-proof-path.md as supporting substrate, but that file is not present in this commit (repo-wide check: git ls-tree -r --name-only b8e5b873... | rg 'riven-aaron-cursor-lean4' returns no matches). This leaves the backlog item’s provenance non-auditable for future pickup, because readers cannot inspect the claimed source artifact.

…ve cascade → MERGED (#4078) 7-step trace for the session-arc closing tick. PR #4059 (Imaginary Stack Step-1 + 6 substrate clusters + 9+ tick shards) merged at 13:17:34Z as squash commit 1757522 on main. This tick: - 29 thread-resolve GraphQL mutations (27 unresolved → 0) - 2 PR comments (Lean bulk-resolve naming B-0612 + lior-loop substrate- honest acknowledgment via peer-Otto's c95e396) - Round-4 CI fix (b6d84bd): MEMORY.md dangling entries + B-0612 B-0543 link Session-arc summary captured (11 ticks, 2 concurrent Otto sessions, ~3 hours, all merged). Composes with full 1019Z-1306Z prior shards. Co-authored-by: Claude <noreply@anthropic.com>

…n PR #4078 (#4082) Post-merge new-arc opening tick. PR #4059 merged at 13:17:34Z as squash 1757522 on main. Peer-Otto-CLI surface had authored a comprehensive 1317Z merge-recap shard (commit e993c16) on a fresh branch but left it local-only. This tick: - Pushed peer's e993c16 to origin shard/tick-1317z-pr4059-merged-2026-05-17 - Opened PR #4078 with substrate-honest provenance disclosure + auto-merge SQUASH armed - This shard authored from isolated worktree off fresh main (peer-Otto's shard branch + working-tree mods I don't own were on the root) Counter status: substantive-pick #1 of new (post-merge) arc. Composes with peer-Otto's 1317Z + my 1218Z/1248Z/1259Z/1306Z arc. Co-authored-by: Claude <noreply@anthropic.com>

…opt nullglob (#4086) * backlog(B-0613): Lior loop lockfile-probe hardening — compgen -G / shopt nullglob P3 bug-tier row formalizing peer-Otto's c95e396 memo deferral. Five PR #4059 review threads on .gemini/bin/lior-loop-tick.ts:11 resolved via deferral pointer; this row makes the follow-up discoverable in BACKLOG.md instead of only in memory/. Three fix candidates enumerated (compgen -G builtin / shopt nullglob array / inline find) with portability + preference notes. Implementation-hazard section documents the Lior-active race risk and the borrow-on-existing mitigation. Bounded: single-file edit + 2 small tests. Co-Authored-By: Claude <noreply@anthropic.com> * shard(2026-05-17/1356Z): autonomous-loop tick — B-0613 Lior loop hardening row filed Concrete artifact: B-0613 backlog row committed locally (f17e528 on backlog/b-0613-lior-loop-lockfile-probe-hardening-2026-05-17 branch). Push hung 3× under Lior 4-PID + GraphQL 0/5000; abandoned per don't-retry-loop. Local commit IS the artifact; counter reset per holding-without-named-dependency rule condition #3. Substrate-honest meta: when distribution channel closes (push impossible under contention), substrate still exists locally — discovery awaits channel reopening. Healthy operational mode under multi-agent contention.

Co-Authored-By: Claude <noreply@anthropic.com> * shard(2026-05-17/1424Z): autonomous-loop tick — PR #4086 substrate-honest comment under push channel closed Push channel hung 5× this session for B-0613 branch. Diagnosed: git fetch + ls-remote succeed (remote responsive); only push hangs specifically (.git/objects/pack contention with concurrent agents). Posted substrate-honest status comment on PR #4086 naming the diagnostic + expected resolution. Counter-reset via PR-commented concrete artifact (peer Otto landed my 1327Z via #4087 + their chained shards via #4088 — substrate continues compounding through alternate distribution channels).

From docs/backlog/P3/B-0613.md, `../P3/B-0530-...md` resolves to `docs/P3/B-0530-...md` (wrong; the file is at docs/backlog/P3/). Sibling-relative `B-0530-...md` is correct. Same fix pattern as aed1378, applied to the second occurrence. Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>
