POC: BPE × R2IL microcode macros — def-use chain carrier, corrected twice - #1018
Conversation
… drops, with a measured design fork
PROBE-STAMP-MORTON-CASCADE-1 (7/7) is the sequel to PROBE-STAMP-CAPACITY-1's
K5: instead of a wider flat register (which the node canon forbids —
"capacity through hierarchy, never field-widening"), read the shipped 64-bit
Stamp word as the FIRST TIER of a Morton 2bit x 2bit 4x4 cascade and let a
colliding leaf lazily materialize a child word.
Measured on the real corpus: 143 distinct evidence sources, cascade pooled
143 / dropped 0, against the shipped Stamp's pooled 64 / dropped 79 —
reproducing K3's finding on the flat side with zero loss on the cascade side.
Conservatism is preserved BY CONSTRUCTION: an absent child means a shared
root leaf is treated as OVERLAP, exactly as Stamp::disjoint would, so
never-false-disjointness holds.
The Pythagorean-comma arm is falsified two-sided (M3): a same-map adversary
[5,69,133,197] collapses 4 distinct ids onto 1 address (level-2 discrimination
gain exactly 0), the comma-rotated map recovers all 4 — and on an unaligned
sub-64 spread both maps agree exactly, so the comma's win is specific to the
adversary, not universal. That paired silence is what keeps it evidence.
MEASURED DESIGN FORK, recorded in the source, NOT decided here: the tier
order is an open question and neither side dominates.
FINE-first (implemented): 1 word at N<=64 — tier 0 is the shipped Stamp
BIT-IDENTICAL, so adopting the cascade would reinterpret no existing
stamp (the "reserve, don't reclaim" posture) — but 65 words at N=143.
COARSE-first (orchestrator-measured, not implemented): 2 words at N<=64,
4 at N=143 (16x cheaper when dense) — but tier 0 stops being the
shipped Stamp.
FINE-first is kept because the backward-compatibility property is
architectural, not a micro-optimisation. Trading it away is the operator's
call. The orchestrator briefly changed the mapping mid-gate and reverted:
the "fix" traded one regime for another, which is a ruling, not a repair.
Also measured: SpoHead is 8 bytes and its temporal field aliases 0 times
across 143 real episodes (folding begins at 256); band-separated pooling
keeps a falsification ledger alive under arbitrary further support, and
empty when never fed one.
Fences: no shipped type modified (Stamp/TruthValue/SpoHead/CausalEdge64
read-only); CascadeStamp is probe-local; the tiers are an INDEX over the
SpoHead receipt stream, never a second ABI; no mint; this is INPUT to the
pending Step-2 stamp ruling, never the ruling.

…ured tension recorded
Operator ruling: Genauigkeit — the cascade serves PRECISION, not memory
concentration. False overlap is the expensive error and the shipped Stamp's
conservatism is built on exactly that, so a coprime stride (never gcd>1) is
the right family and 65 words at N=143 is the honest price.
Constants now phi-Weyl: LEVEL0 = 39 (round(64/phi) = 40 is NOT coprime,
gcd(40,64) = 8, so the nearest coprime value is used), LEVEL1 = 17
(the D-QUANTGATE stride-4-over-17 modulus), WEYL_OFFSET = 21.
MEASURED HONESTY about all three, recorded in source rather than implied:
- For a bijective id->leaf map, EVERY coprime stride is a permutation of
the same leaf set. 39 / 17 / 11 / 41 give IDENTICAL discrimination AND
identical word counts — verified across six candidate pairs and five id
families before adoption. phi-Weyl is a CANONICAL choice
([FORMAL-SCAFFOLD]'s phi-Weyl pillar), NOT a measured performance win.
- The additive offset is a relabeling of the leaf set; it cannot change
occupancy or discrimination. Recorded as convention.
- The probe's earlier "a DIFFERENT multiplier as defense in depth" framing
was UNFOUNDED: M3's comma win comes from reading a DIFFERENT DIGIT, not
a different constant. Corrected at the constant and at child_leaf.
THE TENSION, measured and named (it is why a single constant cannot be
tuned for both): a coprime stride maximizes spread, so all 64 root leaves
fill and every child materializes -> 65 words, maximum discrimination. A
stride with gcd>1 visits only 64/gcd leaves -> stride 4 gives 17 words,
stride 40 (raw phi-Weyl) gives 9 — minimum words, coarser resolution
within a leaf. Anti-moire wants discrimination; amortization wants
concentration. Precision was ruled, so spread was chosen.
LOAD-BEARING CONSTRAINT made explicit at root_leaf: a stamp address must be
a pure function of the SOURCE ID, never arrival order. An arrival-indexed
Weyl walk (offset + k*stride over the k-th arriving source) would make two
stamps carrying the same source compare disjoint or not depending on
insertion order, destroying the meaning of disjoint(). Precision-first
forces the affine-on-id form.
7/7 gates green, unchanged numbers vs the previous constants — which is the
confirmation of the inertness claim above, not a null result.

…omain slot Two probes, one POC: PROBE-BPE-R2IL-LOCO-MICROCODE-1 (10/10) and the companion PROBE-STAMP-MORTON-CASCADE-1 (7/7, already landed in this branch's history, board entry now covers both together). Headline: BPE merges over 1,872 real def-use chain occurrences save 113.4 tokens/merge vs 50.1 for the same algorithm run over the linear opcode stream of the same episodes -- 2.3x denser compression per FnIndex domain slot. Confirms and quantifies #1014's "sequential adjacency is not composition" as a working compressor, not just a diagnostic. FnIndex domain ceiling corrected: DOMAIN_FLOOR=0x90 is const-asserted stored-byte ABI; ogar-ro already mints 22 of the 112-slot domain band, so real headroom for a BPE-learned macro is 0xA6..0xFF = 90 slots, not 255/248. B1 measures 7 R2IL atoms consumed; B2's 33 merges leave 50 free. B6 corrected mid-session, the most important fix in this POC: an earlier framing had this probe invent three self-built admission gates. The real architecture (verified in source) is MUL (contract::mul::GateDecision / Homeostasis / FlowState) as the real gate, and the autopoiesis triangle (ValueTenant::{FrozenStyle,LearnedStyle,ExploreStyle}) as RESONANCE-BASED THINKING, never an RL policy -- PROBE-METACOGNITIVE-TRIANGLE-1 (#998) already proved RungReceipt-only judging, FreeEnergyComparison:: minority_wins(), and Explore running in a counterfactual lane. B6 now ranks candidates via shipped TruthValue::revise + Stamp only, and is explicitly forbidden from freeze/admit/promote/gate vocabulary for its own action -- that belongs to MUL and the triangle, never this probe. Three exploratory cross-checks against shipped precedent, all measuring real effects on this corpus and all labelled exploratory, never architectural: INV1 (HighHeelBGZ's stride-as-role) 33 macros collapse into 21 role classes; INV2 (bgz17 LayeredScope's scent-prune-then-escalate) a cheap opcode-multiset check prunes 80.2% of candidates before the expensive exact walk; INV3 (BGZ-HHTL-D's shared-palette amortization) top macros carry 30-80 episodes-per-mint, confirming real cross-episode reuse. Process: the named next measurement (wider corpora) stayed blocked (r2sleigh absent). A container restart lost the first BPE-probe worker's entire write before it committed; re-dispatched from scratch. The re-dispatched worker introduced two real defects (an atom-count conflation printing chain-occurrence atom-slots, 5616, as if it were the 5340-atom corpus total; several raw Option/tuple Debug-format leaks in printed PASS lines) -- hand-fixed by the orchestrator after a worker fix-attempt only partially landed, reverified by recompiling to ground truth rather than trusting either self-report. Board hygiene same-commit: EPIPHANIES E-BPE-OVER-DEFUSE-CHAINS-BEATS-LINEAR-AND-FITS-LOCO-1 + INTEGRATION_PLANS entry (both assertion-verified writes). Meta-review pending -- three consecutive dispatches died to a transient server-side API 529 Overloaded error before any review content ran; this commit protects the verified, gate-passing work against a further container-restart loss while the review keeps retrying. Any finding it returns lands as a follow-up commit before the PR opens. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KCGhDYoQBXs3poaR7sFuqp
…l, unbuilt) Captures the Frozen=instinct/Learned+Explore=R2IL×BPE architecture the operator laid out during a same-day API outage that blocked meta-review dispatch (4/4 attempts failed to 529). Grounds the genotype claim against this session's own POC measurement (atoms fixed, def-use-chain composition varies, 2.3x denser than linear) and the existing 12-byte StyleLane payload (no new field needed). Proposes four typed recombination operators and a contract check over R2IL's typed operands, routed through the existing FreeEnergyComparison/counterfactual verdict path rather than a new gate. Explicitly labeled PROPOSAL with three unrun falsifiers named in §7 — nothing here is an EPIPHANIES-grade finding yet.

There was a problem hiding this comment.
The number of opcodes in a merge does not determine how many Call.values bytes the macro requires. For example, a three-opcode load/add/store chain can have multiple external live-ins or immediates, while n_atoms - 1 is always two regardless of those operands. Because the probe retains only the expanded opcode count here instead of calculating the macro's live-in/value contract from Episode::ins/outs, the reported 7 Pairs and 26 Triples—and therefore the headline claim that every learned macro fits the real loco geometry—are unsupported.

There was a problem hiding this comment.
The claimed bit-identical fallback to the shipped Stamp is not implemented: shipped Stamp::source(id) sets bit id % 64, whereas this function sets (21 + 39*id) % 64 (for example, source 0 moves from bit 0 to bit 21). Although this permutation preserves occupancy statistics inside the probe, an existing persisted Stamp cannot be used as this root without reinterpretation, invalidating the stated backward-compatibility rationale for selecting fine-first ordering.

These keys are final encoded chain occurrences, not the learned macros in chain_merges: a key may be an untouched atom triple, a merge plus an atom, or multiple merge symbols. Consequently B6 ranks original chain signatures/compositions, and INV3 later labels their episode counts as “episodes-per-mint,” even though no single mint necessarily represents such a key (the reported 27 groups also differ from the 33 learned merges). Track occurrences of each learned merge ID, or explicitly mint complete signatures, before drawing the ranking and amortization conclusions.

Two gates assert facts that their own expressions already guarantee. M4 and M5 both assert properties that follow from the arithmetic written directly above the assertion, so neither gate can fail for a real defect.

M5's temporal assertions restate i % 256.
temporals is built from (0..143).map(|i| i % 256), so 143 distinct values follow from the expression itself. The second assertion compares 256 % 256 with 0 % 256, which is a constant identity. Neither assertion touches SpoHead or the receipt stream. Assert the fold through the receipt field that carries it, for example by writing temporal into SpoHead values and checking distinctness of the stored bytes.
An assertion implied by the code it tests is not a test. As per coding guidelines for **/*.{rs,md}.

…on (architecture review) Three real defects caught by a live codex GitHub review on PR #1018, fixed and reverified by full recompile + rerun against the real corpus, not accepted on the reviewer's word alone: - B5's "immediates_needed" used n_atoms-1 (the BPE merge-tree's internal edge count, a structural constant) instead of the real external Call.values arity from Episode::ins at the opcode's actual operand sites. Re-measured: 7 fit Pairs, 13 fit Triples (was 26), 11 fit Quads (was 0), 2 fit NONE (was 0) - some real macros need more than the pass-1 chain-length-3 extractor's span can address. First fix attempt walked final chain_streams and undercounted (a merge id need not survive to an occurrence's final encoding if a later merge subsumes it); corrected to content-match against each occurrence's original atom sequence, which is order-independent. - B6/INV3 grouped by final-encoding signature (27 groups) and called it "episodes-per-mint," conflating a signature that can bundle several merge ids with a single candidate mint. INV3 now counts per learned merge id directly (33 macros, the correct unit) via the same content-match fix. - Two pre-existing clippy findings (type_complexity, ptr_arg) in untouched code, fixed while in the file. Separately, an architecture review caught a real over-claim: the "90 free FnIndex slots" number was framed as the autopoiesis vocabulary ceiling. It is not - it is the headroom of ONE encoding choice (one FnIndex minted per macro). StyleLane::{Learned,Explore} are 12 palette256-indexed slots, 256 entries each, a separate address space ogar-loco merely routes into. Corrected in the probe's doc comments, both EPIPHANIES/INTEGRATION_PLANS entries, and the companion proposal doc's §1 (which had made the same category error reading the 12-byte lane as one style's ordered macro genome instead of 12 StyleFamily-indexed palette addresses). Also splits PROBE-STAMP-MORTON-CASCADE-1 out to its own PR (orthogonal design decision, muddied this PR's receipt per review) and relabels B3's headline from "2.3x denser compression per domain slot" to "occurrence- stream savings per merge" - the chain-occurrence input overlaps/ double-counts source ops relative to the linear control, so normalizing by merge count alone doesn't establish unconditional compression superiority.

Summary
Autoattended POC answering: R2IL as the faithful/atomic compiler-grade
opcode vocabulary, BPE as an efficient recombination layer over it (never
a second truth), landing as candidate microcode macros, physically stored
in V4.
PROBE-BPE-R2IL-LOCO-MICROCODE-1— 10/10 gates, re-measured twiceafter two independent review passes (a live codex GitHub review + a
separate architecture review). The companion
PROBE-STAMP-MORTON-CASCADE-1was split out to its own PR (#1020) — an orthogonal design decision that
muddied this PR's receipt.
Headline findings (corrected)
for the same algorithm over the linear opcode stream — relabeled from
"2.3x denser compression per domain slot" to "occurrence-stream
savings per merge, not proven compression superiority": the
chain-occurrence input overlaps/double-counts source ops relative to
the linear control, so normalizing by merge count doesn't establish
unconditional compression superiority.
FnIndexslots" number is DEMOTED (the single mostimportant correction, architecture review): it is the headroom of ONE
encoding choice (one
FnIndexminted per macro), not theautopoiesis vocabulary ceiling.
StyleLane::{Learned,Explore}are 12palette256-indexed slots (one per
StyleFamilyordinal), eachaddressing 256 entries in that lane's own palette — a separate
address space
ogar-locomerely routes into, not owns.Episode::insarity, not the BPE merge-tree's internal edge count — 7fit
Pairs, 13 fitTriples(was 26), 11 fitQuads(was 0),2 fit
NONE(was 0, ids 18/38) — the earlier "0 fit NONE" framingwas too triumphant.
final-encoding signatures, not one-per-learned-macro (a group can
bundle several merge ids); INV3 now counts per learned merge id
directly — 33 macros, top-5 episodes-per-mint

Review history
two re-measurements above, plus the underlying final-encoding-vs-
merge-id conflation appearing in both B6 and INV3). All three fixed and
reverified by full recompile + rerun against the real corpus — not

over-claim before merge, and identified the same category error in the
companion proposal doc (

direction rather than holding indefinitely; the codex review above
filled that gap.
