docs(plans)+test: rebaseline #497 OCR plans to #498 + gating probes (5-specialist framing)

Five specialists (cascade / family-codec / palette / dto-soa / truth-architect)
framed the merged #497 OCR-transcode plans against the post-#498 substrate. Two
showstoppers + 6-way drift; all 7 plans corrected:

- HelixResidue 48 B → 6 B everywhere (a stored Signed360 index, not a 48-byte field);
  budgets/carve rebaselined (Full 112, [32,144)); headers #496 → #498.
- "Morton-tile stacked-pyramid perturbation-shader" purged (does not exist; Morton
  rejected for Hilbert) → real primitives (mipmap pyramid / HHTL depth-cascade / CAKES).
- "reversible without a hash" reframed: no residue→rank inverse exists; node =
  identity → content-store lookup, codebook = repair signal (I-VSA-IDENTITIES).
- §0 tripwires: no ValueSchema::Ocr variant (ride Full/Compressed); Meta de-overloaded
  (confidence→Energy, provenance→Plasticity, OOV→content-store); TurbovecResidue is the
  edge codec, glyph→word uses DeepNSM CamCodes.
- master critical path 42→53 becomes 42→{50,51}→53 (resolves the open #497 CodeRabbit Major).

New ocr-probes-v1.md specs the 4 gating probes (OCR-RT/DET/POST/SCHEMA) for the
unmeasured claims (int8-exact LSTM, bit-reproducible diff, 200k-LOC 1:1 layout).
OCR-SCHEMA shipped as a contract test proving OCR rides an existing preset.

+## 2026-06-16 — 5-specialist framing of #497 OCR-transcode plans → plans rebaselined to #498 + probes spec'd
+
+**Main thread (Opus 4.8 1M) + 5 Opus specialists in parallel** (cascade-architect / family-codec-smith / palette-engineer / dto-soa-savant / truth-architect), each read the 7 merged #497 plans + post-#498 source in full (Rule 7 — read, don't grep-judge). Operator: *"review the plans against your awareness of the new architecture incl. the last 15 PR arc (Morton Cascade + Helix 48 + turbovec residue) — send 5 specialist framing it."* See `EPIPHANIES.md` E-OCR-PLAN-DRIFT-1 for the consolidated framing.
+
+**Two showstoppers:** (1) the "reversible without a hash" migration rationale is FALSE in code (no `residue→rank` inverse; `vocabulary.rs` is a stored string-table keyed by rank) — truth-architect; (2) the "Morton-tile stacked-pyramid perturbation-shader cascade" does NOT exist (0 hits; Morton rejected for Hilbert) — cascade-architect. **Convergent drift (≥4 lenses):** dead 48 B HelixResidue (now 6 B), D-OCR-50 already shipped (#498), `ValueSchema::Ocr`/`Meta`-5-jobs/`TurbovecResidue`-wrong-carrier §0 tripwires, HHTL = coherent address-trie not a blur.
+
+**Outcome:** all 7 plans corrected on `claude/wonderful-hawking-lodtql` (rebaselined #496→#498, Morton purged, reversibility reframed, §0 tripwires fixed, master critical-path fixed = the open CodeRabbit Major on #497). New `ocr-probes-v1.md` (4 gating probes OCR-RT/DET/POST/SCHEMA + 3 cascade perf probes). **OCR-SCHEMA shipped as a contract test** (`ocr::tests::ocr_schema_fit_rides_existing_preset_no_new_variant`). contract 620 lib green; fmt clean. Both #497 + #498 review threads resolved/dispositioned.
+
+**Next:** open the follow-up PR; run OCR-DET (deepnsm example) + OCR-RT (needs deepnsm+helix wiring) before any transcode code is funded.

+## 2026-06-16 — E-OCR-PLAN-DRIFT-1 — the #497 OCR-transcode plans drifted from the substrate in 6 ways; 2 were showstoppers
+
+**Status:** FINDING (5-specialist framing — cascade-architect / family-codec-smith / palette-engineer / dto-soa-savant / truth-architect, each read the merged plans + source in full).
+**Confidence:** High — every claim cited plan file:line vs current source file:line; convergent across ≥4 lenses for the load-bearing ones.
+
+**Context.** #497 (Tesseract→tesseract-rs transcode plan family, 7 design docs) and #498 (helix `Signed360` + GUID keystone) merged within hours. The #497 plans were authored against the pre-#498 branch, so they reason against a substrate that shifted under them. Five specialists framed the merged plans against the post-#498 architecture.
+
+**The two showstoppers:**
+1. **The "reversible without a hash" rationale is false in code** (truth-architect). The migration's headline — "OCR text reconstructs from residue + codebook, no string column" — has no support: `deepnsm/vocabulary.rs` maps `rank→&str` via a stored table, every decode entry point takes a *known* rank as input, and there is no `residue→rank` inverse (helix encode is lossy). The "reversible residue" was a renamed stored string-table keyed by index — the very thing it claimed to avoid.
+2. **The "Morton-tile stacked-pyramid perturbation-shader cascade" does not exist** (cascade-architect). 0 hits in either repo; Morton is explicitly *rejected* for Hilbert (`linalg/hilbert.rs:50`). Three deliverables (D-OCR-52, the reconstruction round-trip, the whole soa-centroid synthesis plan) were built on a fabricated subsystem name.
+
+**Convergent drift (≥4 lenses):**
+- Plans argue "HelixResidue is 48 B, category-wrong, don't use it" — #498 made it **6 B** (a stored `Signed360` place index), which IS the keep-the-index design the plan wanted. Every byte budget was dead (Full 154→112, carve `[32,186)`→`[32,144)`).
+- D-OCR-50 (`LayoutBlock::to_node_row`) already SHIPPED in #498 — described as future work.
+- §0 tripwires: `ValueSchema::Ocr` (5th preset variant = anti-invention violation; ride Full/Compressed); `Meta` u64 overloaded 5 ways (split → Energy/Plasticity/residues/content-store); `TurbovecResidue` is the *edge* codec (rank-only fidelity) — wrong carrier for glyph→word (use DeepNSM CamCodes).
+- HHTL Doc→Page→Block→Line→Token onto HEEL/HIP/TWIG+family is a *coherent address-trie, NOT a Frankenstein* (family-codec + cascade) — but it spends the similarity-basin semantics on layout, so OCR nodes must be `classid`-marked as layout-addressed.
+
+**Disposition.** All 7 plans corrected (rebaselined to #498; Morton purged → real primitives `framebuffer::build_mipmap_pyramid` / `splat3d/depth_cascade` / CAKES; reversibility reframed to identity→content-store + codebook-as-repair-signal; §0 tripwires fixed; master critical-path fixed per the open CodeRabbit Major). Unmeasured claims (int8-exact LSTM, bit-reproducible diff, 200k-LOC 1:1 layout) gated behind 4 probes in `ocr-probes-v1.md` (OCR-RT/DET/POST/SCHEMA); **OCR-SCHEMA shipped as a contract test** proving OCR rides an existing preset (no new `ValueSchema` variant).
+
+**Lesson.** When two PRs touch the same substrate within hours, the later merge silently invalidates the earlier plan's premises. Plans citing sizes/budgets/file:line must be rebaselined the moment a substrate PR lands — and "reversible / never-stored" claims must be PROVEN against the actual decode path before becoming a migration's rationale.

+*repair / disambiguation*, never a reversible text payload.

+| Tenant (existing, post-#498 sizes) | OCR role |
 |---|---|
-| helix residue = **centroid attention field** (NOT a stored code) | The 24-bit golden index is the **query↔centroid alignment** (φ-spiral direction = how this point attends to its place-centroid); the Morton-tile stacked-pyramid perturbation-shader is **multi-scale attention** (coarse centroid → fine perturbation = HHTL cascade in residue space). The field is **evaluated from the φ-template, never stored** ("8K resolution at Super-8 cost" — only the index is kept). Place=HHTL centroid; residue=perturbation off it. The 48-byte `ValueTenant::HelixResidue` is category-wrong (stores a field that must be computed) — do NOT use it. |
-| `TurbovecResidue` (16 B, PQ) | PQ edge residue → CAKES nearest-valid-token search over the codebook |
-| `Meta` (u64) | codebook index/anchor + confidence + char-confusion/NSM-repair flags + recoder-code fallback for true-OOV |
+| `HelixResidue` (**6 B = 48 bit `Signed360`**, NOT 48 B) | A **stored** golden-spiral *place index* (rim 3 B + sign-partition polar 1 B + golden azimuth 2 B; `helix/src/residue.rs:63-116`). The 6 B IS the kept index; the multi-scale field is the *deterministic decode* of it (`RollingFloor::quantize` / `HemispherePoint::lift`, pure `&self`) — "8K resolution at Super-8 cost." It is a place code, **not** a confidence carrier. (The old "48-byte, category-wrong, do NOT use it" line was written pre-#498 against a bits→bytes slip; the tenant is **6 B** and is exactly the keep-the-index design — use it.) |
+| `TurbovecResidue` (16 B, `Pq32x4`) | The **edge-block** PQ residue (`EdgeCodecFlavor::Pq32x4`, rank-preserving / absolute-distance-lossy, ICC 0.11–0.29). NOT the glyph→word carrier — nearest-**valid**-token needs absolute distance, so the glyph→word search uses **DeepNSM's `Codebook` CamCodes** (6×256×16, 6 B; `deepnsm/src/codebook.rs`) + `vocabulary.rs` reverse, not this tenant. |
+| `Meta` (u64) | A SMALL codebook anchor only (a ≤12-bit vocab rank fits). It does NOT carry confidence (→ `Energy`, shipped `ocr.rs:112-114`), repair flags (→ `Plasticity`), or the OOV recoder-code (→ external content store). `Meta` is the cognitive `MetaWord`; overloading it 5 ways is an I-LEGACY-API-FEATURE-GATED hazard (one u64, different meaning per class). Prefer a future `ValueTenant::OcrEvidence` (OD-1) for OCR-specific evidence. |

-**Reconstruction (this is the round-trip, and it answers Codex P1):**
-`text  ⇄  codebook_index(Meta) + field-eval(helix 24-bit golden-index attention ⊕ TurbovecResidue PQ)`. Decode =
-the DeepNSM Morton-tile **stacked-pyramid perturbation-shader cascade** applied to
-the residue → CAKES nearest-valid-token over the codebook (DeepNSM `vocabulary` /
-coca `word_frequency`) → the word. No `Fingerprint` hash, no string column. The
-reversibility lives in residue + codebook, which is the architecture's whole point.
-
-**True-OOV (no codebook neighbor — a raw code like `69B8`):** falls back to the
-**recoder-code residue** — `recodebeam` already emits recoder codes, not pixels, so
-the codes themselves are the reversible payload in `Meta`, repaired by the
-char-confusion grammar (D-OCR-52). Still a residue, never a hash.
-
-**ValueSchema:** `Cognitive` does NOT include `HelixResidue`/`TurbovecResidue`, so
-OCR needs a dedicated **`ValueSchema::Ocr`** = `FieldMask` over
-{`HelixResidue`,`TurbovecResidue`,`Meta`,`EntityType`,`Plasticity`}. Selection only;
-moves no tenant (canon: tenants never move/reuse).
+**Recognition vs reconstruction — be precise (corrects the pre-#498 framing).**
+The recognized string is recovered by **identity → external content-store lookup**,
+not by inverting a residue. There is **no `residue → codebook-rank` inverse** in the
+code: `deepnsm/vocabulary.rs` maps `rank → &str` via a stored table, and every
+`nearest_words(rank,k)` / `word_neighbors(word,k)` entry point takes a *known*
+rank/word as input. So "reversible without a hash" is NOT a property of the substrate
+today — the codebook code is a **repair / disambiguation signal**, not a lossless
+text payload. The honest mapping:
+- **text** → external content store keyed by `identity` (I-VSA-IDENTITIES).
+- **`Meta` codebook anchor + `TurbovecResidue` / `HelixResidue`** → similarity
+  coordinates that feed *repair* (DeepNSM plausibility + char-confusion + CAKES
+  nearest-valid-token), NOT round-trip text recovery.
+- the multi-scale decode uses the **real** primitives — `framebuffer::build_mipmap_pyramid`
+  / the HHTL `splat3d/depth_cascade` / the helix φ-template / the CAKES ladder
+  (`high_heel.rs:16-24`) — there is **no** "Morton-tile stacked-pyramid perturbation-shader"
+  in either repo (Morton is explicitly rejected for Hilbert in `linalg/hilbert.rs:50`).
+- **Gate:** if a measured `residue → rank` round-trip is ever wanted, it must be
+  PROVEN first (probe **OCR-RT**, see `ocr-probes-v1.md`) — it is CONJECTURE today.
+
+**True-OOV (a raw code like `69B8`):** `recodebeam` emits recoder codes; the code +
+its char-confusion repair (D-OCR-52) live in the content store with the token text,
+keyed by `identity`. Not bundled into the node.
+
+**ValueSchema:** do **NOT** add a 5th `ValueSchema::Ocr` enum variant — that is a
+contract-surface addition against the #496 §0 anti-invention guardrail. Shipped
+`ocr.rs` already transcodes by riding the POC-`Full` default (`classid_read_mode →
+Full`) and writing only the tenants it populates. Post-POC, OCR rides the existing
+**`Compressed`** preset (already = Fingerprint + HelixResidue + TurbovecResidue +
+EntityType) — or, if a distinct tenant set is truly needed, **mint an OCR class** in
+OGAR whose `ClassView` selects existing tenants (the §0-sanctioned opt-in route).
+New capability = new column/class, never a new enum variant.
