The +two projects are _siblings_, not a fork — they share design principles +but diverge in dialect scope and proof strategy. -[IMPORTANT] -==== -**`README.md` is the canonical README for this repository.** +For a gentler entry point see EXPLAINME.adoc. -This AsciiDoc file is retained because estate tooling references it.

The dialects are **nested subsets, not four co-equal languages**: `solo` (affine, single-agent) ⊂ `duet` (session-typed, two-party) ⊂ `ensemble` (multi-agent) — the full language. `me` (visual/pedagogic) is **not** a fourth dialect but an on-the-fly *projector* that cuts the hierarchy at a chosen point; its Rust scaffolding is sidelined in `_exploratory/me-scaffolding/`.

Product/elimination decision settled (additive `&` + multiplicative `⊗` both coherent). Idris twin pending (Phase F5 parity). | -| **Usage-walk checker** (`check`) | *machine-checked (Coq)* — Phase **F1.4 tail / R5 done**: `check : tctx → tm → option (ty × uvec)` synthesises type **and** usage in one bottom-up pass, with `check_correct : has_type G D t a ↔ check G t = Some (a, D)` a real `Qed.` (axiom-free, CI-guarded). This is the decidability/adequacy of QTT typing — the executable spec the Rust `dialects/solo` checker (still `TODO(#typeck)`) must meet, and it **overtakes AffineScript** (whose solo-core leaves the same equivalence as prose "future work"). **R5b** further decides the affine budget judgement (`aff_type_dec`). | -| **me → solo elaboration** (`elab`, `elab_data_check`, `me_wt_sound`) | *machine-checked (Coq)* — **M1.0 / M1.1 / M1.1b done**: the visual `me` surface ([`proofs/me/`](proofs/me/)) elaborates into the solo core. `elab : me_tm → tm` is a core-landing analogue of the paper `translate`. **M1.1** `elab_data_check` is the axiom-free Visual-Soundness theorem for the no-linear-use data fragment; **M1.1b** adds a me typing judgement `me_wt` with `me_wt_sound : me_wt G D e a → has_type G D (elab e) a` covering the linear-use constructs (token-consume / `MeLet` / pair-split / the faithful `MeIf → Case` conditional) **universally** — spanning the whole `me_tm` (incl. `MeSeq`, closed via the F1.4 `ht_shift0` weakening lemma). The first mechanised surface→core elaboration-correctness result in either sibling — AffineScript, as surveyed (`proofs/ALIGNMENT-PLAN.md` §1, AS@main 2026-06-02), is solo-only with no `me`-like dialect. | -| **Ensemble session-π core** (`SessionPi.v`: `proc`, `sty`/`dual`, `wt`, `step`) | *machine-checked (Coq), definitions + witnesses* — **S1.0 done (axis-2 STRUCTURE)**: a standalone Coq development for the ensemble session-typed π-calculus (binary, synchronous) after [`proofs/duet/session-types/`](proofs/duet/session-types/) + [`proofs/ensemble/agent-calculus/`](proofs/ensemble/agent-calculus/). Session types with a computed duality + `dual_involutive`, polarised endpoints, a *linear* channel-typing judgement with context splitting, and small-step reduction for the communication redex; executable witnesses (a well-typed ping-pong that reduces) are real `Qed`, **axiom-free** and CI-guarded. **S1.1a/S1.1b done**: the first-order value-substitution lemma (`wt_subst`) and **subject reduction for the communication redex** (`sr_comm`) are real axiom-free `Qed`; and **full closed-system subject reduction** (`config_subject_reduction : wf_config c → cstep c c' → wf_config c'`) is proved axiom-free via the fused two-party `(νc)(P∣Q)` form (the duet T-Session primitive), where the shared protocol advances locally so well-formedness (both endpoints dual) is preserved across communication. **S1.2 done**: **session fidelity** (`session_fidelity` — a communication advances the protocol by exactly one `sty_step`) and **progress / deadlock-freedom** (`config_progress` — a well-formed config is fully ended or can step), the duet paper's safety+liveness theorems for the binary fragment, both axiom-free. **S2.0/S2.1 done — duet by projection**: a multiparty-*shaped* global-type layer `gty` + the three-case projection `proj G r` (sender `!` / receiver `?` / uninvolved passthrough) + the two-party restriction `two_party`, with **`projection_duality`** (a two-party choreography projects to DUAL local types — `p≠q` load-bearing) and **`projected_config_wf`** + corollaries that *transport the whole S1.1b/S1.2 guarantee across projection* (subject reduction, fidelity, progress) — so a config obtained by projecting a choreography is deadlock-free BY CONSTRUCTION, all axiom-free. Honest fence: message-passing + end only; it *instantiates* the thesis on two-party choreographies (not a general n-party result); choice/μ landed at **S2.2** (below) and n≥3 coherence (S3) is OUT. **S1.3 done — choice / congruence / μ type-layer**: **S1.3a** extends the three fused theorems with **n-ary labelled choice** (`SSelect`/`SBranch`/`QSel`/`QBra` over dedicated mutual inductives, label-mismatch safety expressible); **S1.3c** proves structural congruence preserves typing on the open `proc` (`wt_congr`, par laws); **S1.3b-core** adds the equi-recursive **μ type-layer** (`SMu`/`SVar`, `unfold_mu`, `dual_unfold`, `guarded`) — the S2.2 projection target — all axiom-free. (μ typing/SR up-to-unfolding = S1.3b-meta, honestly deferred.) **S2.2 done — choice + recursion by projection**: global types gain labelled choice `GBra p→q:{lᵢ:Gᵢ}` + equi-recursive `GMu`/`GVar`; projection becomes **partial** (`proj : gty → role → option sty`, three-way mutual) with a plain **`merge`** (keystone `merge_idem`) combining the branches for an uninvolved role, and **`projection_duality`** is reproved in **option-map form** over choice + μ (mutual `two_party_mut` scheme), the whole bridge rethreaded through `proj … = Some _`. Design-panel-validated (caught a real None-erasure soundness bug pre-implementation). Honest fences: **plain** (not label-union) merge, **unpruned** μ projection, **no global-level metatheory**; full-union merge + n-party safety = **S3c**. **S3a done — n-party projection totality**: the **first theorem quantifying over a genuine n≥3 role space**, **`projection_total : projectable_wf G → ∀ r:role, ∃ s, proj G r = Some s`** (every role of a well-branched global type projects), via the mutual `projectable_wf_mut` scheme; non-vacuity pinned at n=3 by a 3-party ring (projects on all roles, not `two_party`) and an agreeing 3-party choice (uninvolved role projected via a non-trivial `merge`), with the plain-merge boundary witnessed (a same-direction different-payload choice is a SAFE protocol that plain merge rejects). Honestly named `projectable_wf` (projection EXISTENCE, **not** safety); the general `two_party → projectable_wf` is **not** proved (it is false — `two_party` is strictly more permissive), so the n=2 collapse is witnessed by example. **S3b done — static n-party configuration**: the first n-party *configuration* form — `role_assignment := list (role*party)` + the In-based **`wf_assignment`** (every listed endpoint typed at its role's projection), with the binary `Conf`/`wf_config` recovered as the **n=2 slice** (`conf_is_role_assignment2`, reusing `projected_config_wf`) + converse embed, an n=3 non-`Conf` static witness over `g_ring` (`wf_ra_ring`), and honesty witnesses (duplicate-key tolerance → no functionality theorem; `projectable_but_uncoverable` → no general "projectable ⇒ coverable") — static only, `wf_assignment` = typed-at-projection NOT n-party safety, no operational n-party metatheory. **S3c.0 done — full label-union merge**: the Honda-Yoshida-Carbone `umerge` (keystone `umerge_idem`) added *alongside* the plain merge, unlocking different-**label** external (`&`) choices the plain merge rejects (witnessed `umerge_widens_strictly`); type-algebra only, and it does **not** unlock the different-**payload** `g_excluded` class (unions labels, not payloads). **S3c.1 done — union-projection**: a SEPARATE `proj_u` (plain `proj` with the uninvolved fold's `merge` replaced by `umerge`) added *alongside* `proj` (canonical `proj`/`merge`/`projectable_wf` byte-identical, NOT re-pointed), with the union projectability predicate `projectable_u_wf`, the keystone existence theorem **`projection_total_u`** (every role of a `projectable_u_wf` global type union-projects), and the one-directional monotonicity bridge **`projectable_wf_implies_u`** (every plain-projectable `G` is union-projectable, projections coinciding) riding on the keystone **`merge_forces_eq`** (plain merge is the identity-meet); non-vacuity `g_union3` (uninvolved role sees `&{3:end}` vs `&{4:end}` — different **labels**) is genuinely in *union-projectable minus plain-projectable*; projection-EXISTENCE only (no n-party safety), the bridge is DOMAIN-INCLUSION (converse FALSE). **S3c.2 done — n-ary located operational semantics**: the first operational metatheory over an n-party config — a located reduction `nstep` (the located mirror of the fused binary `cstep`: one communication `ra_set`-updates exactly the two communicating roles) + `ra_set` + a global-type reduction `gstep` + closures `nstar`/`gstar` + the functional `wf_assignment_f` (`wf_assignment_to_f` keeps S3b green); the 3-party ring run `0→1→2→0` to all-`QEnd` is witnessed on both sides (`ring_runs_to_end`, `g_ring_gsteps`). Adequacy ONLY: the load-bearing `nstep_breaks_wf_at_fixed_G` *proves* `nstep` does not preserve `wf_assignment_f` at a fixed `G` (so n-party SR must be stated against a *stepping* `G`), no progress. **S3c.3-msg done — head-coupled message subject reduction**: the first EARNED n-party safety half — `nstep_sr_msg_head` proves the **head** communication carries wf from `GMsg p q t G'` to its continuation `G'` (3-way located role split; the SAME `v:t` the sender ships is what the receiver substitutes), coupled corollary `nstep_gstep_sr_msg_head`. The SAME `ra_ring1` S3c.2 refuted at the fixed `g_ring` IS wf at the *stepped* `g_ring` (`ra_ring1_wf_at_stepped_g`, sealed by `sr_earns_safety_across_step`); the run-ahead fence is self-witnessed (`runahead_breaks_head_coupling`). Design-panel-validated + adversary-verified (*sound-and-honest*); HEAD message fragment, preservation only. Deferred: run-ahead/permutation SR (**S3c.3-perm**), select SR (**S3c.3-choice**), n-party progress (**S3c.4** — research-hard, fence).

For that fragment it is the first mechanised surface→core elaboration correctness in either sibling, as surveyed against AS@main 2026-06-02 (axis-4 SURFACE rung M1). **S1 + S2 done (2026-06-14)**: the *structure climb* (axis-2) is mechanised in the standalone Coq development `SessionPi.v` — a synchronous binary session-typed π-calculus core (session types + computed duality, polarised endpoints, a linear channel-typing judgement, small-step reduction) with **subject reduction** (`sr_comm`, `config_subject_reduction`), **session fidelity** (`session_fidelity`) and **progress / deadlock-freedom** (`config_progress`) for the binary fragment (**S1.0–S1.2**), and the **duet-by-projection** layer (**S2.0/S2.1**) — multiparty-shaped global types, the three-case projection, `projection_duality`, and corollaries that transport the whole S1 guarantee across projection so a projected choreography is deadlock-free by construction — all axiom-free and CI-guarded. **S1.3 done (2026-06-14)**: n-ary labelled **choice** (S1.3a, the three fused theorems extended), structural **congruence** preserves typing (S1.3c, `wt_congr`), and the equi-recursive **μ type-layer** (S1.3b-core: `unfold_mu`/`dual_unfold`/`guarded`). **S2.2 done (2026-06-14)**: global-type labelled **choice** (`GBra`) + equi-recursive (`GMu`/`GVar`) projection — projection is now **partial** (`option sty`) with a plain **`merge`** (keystone `merge_idem`) for uninvolved roles and `projection_duality` reproved in option-map form over choice + μ; fenced as plain (not union) merge, unpruned μ, no global-level metatheory. **S3a done (2026-06-14)**: the first n≥3 theorem — `projection_total` (every role of a `projectable_wf` global type projects), breaking the "no theorem quantifies over a genuine n-party system" fence. **S3b done (2026-06-14)**: the first n-party *configuration* form — `role_assignment` + the In-based `wf_assignment`, the binary `Conf` recovered as the **n=2 slice** (`conf_is_role_assignment2`, reusing `projected_config_wf`), an n=3 non-`Conf` witness over `g_ring`, and honesty witnesses (duplicate keys; projectable-but-uncoverable); static only — `wf_assignment` = typed-at-projection NOT n-party safety. **S3c.0 done (2026-06-14)**: the full label-union merge `umerge` (keystone `umerge_idem`) added alongside the plain merge — type-algebra only, unlocks different-label `&` choices (not the different-payload class). **S3c.1 done (2026-06-14)**: a SEPARATE union-projection `proj_u` (the only token changed from `proj` is `merge`→`umerge` in the uninvolved fold) + `projectable_u_wf` + the keystone existence theorem `projection_total_u` + the one-directional monotonicity bridge `projectable_wf_implies_u` (on the keystone `merge_forces_eq`: plain merge is the identity-meet); canonical `proj` byte-identical, projection-EXISTENCE only, non-vacuity `g_union3` genuinely in *union-projectable minus plain-projectable*. **S3c.2 done (2026-06-14)**: the first operational metatheory over an n-party config — a located reduction `nstep` (located mirror of the fused `cstep`) + `ra_set` + a global `gstep` + `nstar`/`gstar` + the functional `wf_assignment_f` (`wf_assignment_to_f` keeps S3b green); the 3-party ring run witnessed both sides (`ring_runs_to_end`, `g_ring_gsteps`); adequacy ONLY — `nstep_breaks_wf_at_fixed_G` proves no fixed-`G` subject reduction. **S3c.3-msg done (2026-06-14)**: the first EARNED n-party safety half — `nstep_sr_msg_head` (head-coupled message subject reduction, 3-way located role split), coupled corollary `nstep_gstep_sr_msg_head`, the earned-safety headline `sr_earns_safety_across_step` (the same `ra_ring1` S3c.2 refuted at the fixed g is wf at the stepped g), and the self-witnessed run-ahead fence `runahead_breaks_head_coupling`; adversary-verified sound-and-honest.

Top-level `+let+` → zero-arg `+fn+` + +AffineScript’s grammar (`+top_level+` in `+parser.mly+`) allows only +`+fn+`, `+type+`, `+effect+`, `+trait+`, `+impl+`, `+const+`, and +`+extern+` at module top level — *there is no top-level `+let+`*. +`+const+` exists but every example in the reference uses it for +_scalars_ only (`+const PI: Float = ...+`); no `+.affine+` file uses a +`+const+` initialised to a record/array/enum value. + +So each ReScript top-level binding of a record/array value +(`+let names+`, `+let personality+`, `+let teaches+`, `+let lessons+`, +`+let agent+`) became a *zero-argument public function* returning that +value: + +.... +pub fn names() -> AgentNames { #{ ... } } +.... + +and every reference was updated to a call: `+names.cuttle+` → +`+names().cuttle+`, `+personality.encouragement+` → +`+personality().encouragement+`. This is the idiom the whole stdlib uses +(functions returning records/arrays) and is definitely supported. +Trade-off: the value is rebuilt on each call rather than shared — +semantically identical for this pure, immutable data. + +==== 2. RNG (`+Js.Math.random_int+`) — INFERRED + +`+stdlib/Deno.affine+` declares +`+pub extern fn random_in_range(lo, hi) -> Int+` ("`uniform integer draw +in `+[lo, hi)+``", lowered to `+Math.floor(Math.random()*(hi-lo))+lo+` +on the `+--deno-esm+` backend). That is an exact match for ReScript +`+Js.Math.random_int(0, len)+`, so `+random_element+` in +`+Types.affine+` uses it via `+use Deno;+` + +`+Deno::random_in_range(0, n)+`. + +I deliberately did *not* hand-roll +`+floor(math_random() * to_float(n))+` (the suggestion in the task) +because: * `+floor+`’s signature is `+Float -> Int+` (a builtin), and +there is *no `+*.+` float-multiply operator* — `+math.affine+` +multiplies floats with plain `+*+` (`+degrees * PI / 180.0+`). So the +hand-rolled form would be `+floor(math_random() * float(n))+`, which +works, but * `+random_in_range+` is the purpose-built primitive and is +clearer/safer. + +*Caveat / coupling:* importing `+Deno+` ties `+Types.affine+` (hence +every agent) to a host providing `+Deno::*+` (the `+--deno-esm+` backend +or the `+affine-deno+` runtime shim). This is acceptable because the +original targeted JS/Deno (`+Js.Math+`), but a non-Deno backend would +need the RNG call swapped. *Unverified:* that `+Deno::random_in_range+` +resolves cleanly for a non-`+main+` library module under `+check+`. + +==== 3. Array-index "`random element or fallback`" + +ReScript `+arr[idx]->Option.getOr(fallback)+` relies on indexing +returning `+option+`. In AffineScript `+arr[i]+` returns the *element +directly* (verified: `+collections.affine+` `+list[0]+`, +`+option.affine+` `+list[index]+`), and `+len+` gives the length. So the +idiom became the `+random_element(arr, fallback)+` helper in +`+Types.affine+`: + +.... +pub fn random_element(arr: [String], fallback: String) -> String { + let n = len(arr); + if n > 0 { arr[Deno::random_in_range(0, n)] } else { fallback } +} +.... + +Behaviour preserved: a uniformly-random element, or the fallback when +empty. (The original could never actually hit the fallback for the +non-empty personality arrays; the helper keeps the same safety net.) + +==== 4. Module aliasing AND a forced rename — the important one + +ReScript `+module Red = RedAgent+` + `+Red.getName(stage)+` namespaces +each agent. AffineScript supports `+use RedAgent as Red;+` and qualified +value paths `+Red::red_get_name(x)+` (verified in `+parser.mly+`: +`+upper_ident COLONCOLON lower_ident+` → `+ExprField+`, lowered by +`+Resolve.lower_qualified_value_paths+`). + +*However* — and this is the subtle part — +`+lower_qualified_value_paths+` *erases the qualifier*: +`+Red::red_get_name+` is rewritten to the bare `+red_get_name+`, and the +module loader _flat-imports_ every imported module’s public functions +*by name into one namespace*, deduplicating on collision +(`+module_loader.ml+` `+already_in+`). If all seven agents each exported +a function literally named `+get_name+`, the seven `+get_name+`s would +collide and only the first would survive — the per-module qualifier +cannot disambiguate them because it is gone before resolution. + +*Decision:* each agent’s _stage-dispatched_ public functions are +uniquely prefixed with the colour: `+red_get_name+`, +`+orange_get_name+`, …, `+red_get_hidden_concept+`, …, +`+red_reveal_text+`, …, +`+red_encourage+`/`+red_correct+`/`+red_celebrate+`. The data accessors +(`+names+`, `+personality+`, `+teaches+`, `+lessons+`, `+agent+`) keep +their plain names because they are *only called within their own +module*, never cross-module, so they never collide in `+RevealSystem+`’s +import set. + +This changes the public API names of the per-agent functions but +preserves all behaviour and is the faithful way to compile. +`+RevealSystem+` still reads naturally: `+Red::red_get_name(stage)+`. + +*Unverified:* whether the resolver is happy with `+use X as Y;+` where +the flattened public set is large; and whether `+agent()+`/`+names()+` +etc. (same name across modules) cause a problem _in RevealSystem_ — they +should not, because `+RevealSystem+` never imports those names (it only +imports `+Types::{...}+`, `+prelude::{...}+`, and the seven agents _as +aliases_; the aliased ImportSimple still flat-imports the modules’ +public fns by name, so the seven +`+names+`/`+personality+`/`+agent+`/etc. *do* collide in RevealSystem’s +flattened set). RevealSystem never _calls_ those collided names, so it +is harmless for type-checking RevealSystem’s own bodies — but if the +loader rejects duplicate flat imports outright (rather than deduping), +RevealSystem would fail to load. The observed loader behaviour +(`+already_in+` dedup, no error) suggests dedup, not rejection. *This is +the single most likely place to need a fix once a compiler is available* +— the robust fallback is to also prefix +`+names+`/`+personality+`/`+teaches+`/`+lessons+`/ `+agent+` per colour +(e.g. `+red_agent()+`), at the cost of more churn. + +==== 5. `+filterMap+` + `+Option.map+` + +`+RevealSystem.generateStageReveal+` used +`+colors->Array.filterMap(c => getRevealText(...)->Option.map(t => (c, t)))+`. +The stdlib _does_ provide `+option::map_filter+` and `+option::map+`, +but they are *not `+pub+`* (only `+option::unwrap_or+` is `+pub+`), so +they cannot be cross-module imported.

Top-level `let` → zero-arg `fn` - -AffineScript's grammar (`top_level` in `parser.mly`) allows only `fn`, -`type`, `effect`, `trait`, `impl`, `const`, and `extern` at module top level — -**there is no top-level `let`**. `const` exists but every example in the -reference uses it for *scalars* only (`const PI: Float = ...`); no `.affine` -file uses a `const` initialised to a record/array/enum value. - -So each ReScript top-level binding of a record/array value -(`let names`, `let personality`, `let teaches`, `let lessons`, `let agent`) -became a **zero-argument public function** returning that value: - -``` -pub fn names() -> AgentNames { #{ ... } } -``` - -and every reference was updated to a call: `names.cuttle` → `names().cuttle`, -`personality.encouragement` → `personality().encouragement`. This is the -idiom the whole stdlib uses (functions returning records/arrays) and is -definitely supported. Trade-off: the value is rebuilt on each call rather -than shared — semantically identical for this pure, immutable data. - -### 2. RNG (`Js.Math.random_int`) — INFERRED - -`stdlib/Deno.affine` declares `pub extern fn random_in_range(lo, hi) -> Int` -("uniform integer draw in `[lo, hi)`", lowered to -`Math.floor(Math.random()*(hi-lo))+lo` on the `--deno-esm` backend). That is -an exact match for ReScript `Js.Math.random_int(0, len)`, so `random_element` -in `Types.affine` uses it via `use Deno;` + `Deno::random_in_range(0, n)`. - -I deliberately did **not** hand-roll `floor(math_random() * to_float(n))` -(the suggestion in the task) because: -* `floor`'s signature is `Float -> Int` (a builtin), and there is **no `*.` - float-multiply operator** — `math.affine` multiplies floats with plain `*` - (`degrees * PI / 180.0`). So the hand-rolled form would be - `floor(math_random() * float(n))`, which works, but -* `random_in_range` is the purpose-built primitive and is clearer/safer. - -**Caveat / coupling:** importing `Deno` ties `Types.affine` (hence every -agent) to a host providing `Deno::*` (the `--deno-esm` backend or the -`affine-deno` runtime shim). This is acceptable because the original targeted -JS/Deno (`Js.Math`), but a non-Deno backend would need the RNG call swapped. -**Unverified:** that `Deno::random_in_range` resolves cleanly for a -non-`main` library module under `check`. - -### 3. Array-index "random element or fallback" - -ReScript `arr[idx]->Option.getOr(fallback)` relies on indexing returning -`option`. In AffineScript `arr[i]` returns the **element directly** (verified: -`collections.affine` `list[0]`, `option.affine` `list[index]`), and `len` -gives the length. So the idiom became the `random_element(arr, fallback)` -helper in `Types.affine`: - -``` -pub fn random_element(arr: [String], fallback: String) -> String { - let n = len(arr); - if n > 0 { arr[Deno::random_in_range(0, n)] } else { fallback } -} -``` - -Behaviour preserved: a uniformly-random element, or the fallback when empty. -(The original could never actually hit the fallback for the non-empty -personality arrays; the helper keeps the same safety net.) - -### 4. Module aliasing AND a forced rename — the important one - -ReScript `module Red = RedAgent` + `Red.getName(stage)` namespaces each -agent. AffineScript supports `use RedAgent as Red;` and qualified value paths -`Red::red_get_name(x)` (verified in `parser.mly`: `upper_ident COLONCOLON -lower_ident` → `ExprField`, lowered by `Resolve.lower_qualified_value_paths`). - -**However** — and this is the subtle part — `lower_qualified_value_paths` -**erases the qualifier**: `Red::red_get_name` is rewritten to the bare -`red_get_name`, and the module loader *flat-imports* every imported module's -public functions **by name into one namespace**, deduplicating on collision -(`module_loader.ml` `already_in`). If all seven agents each exported a -function literally named `get_name`, the seven `get_name`s would collide and -only the first would survive — the per-module qualifier cannot disambiguate -them because it is gone before resolution. - -**Decision:** each agent's *stage-dispatched* public functions are uniquely -prefixed with the colour: -`red_get_name`, `orange_get_name`, …, `red_get_hidden_concept`, …, -`red_reveal_text`, …, `red_encourage`/`red_correct`/`red_celebrate`. The -data accessors (`names`, `personality`, `teaches`, `lessons`, `agent`) keep -their plain names because they are **only called within their own module**, -never cross-module, so they never collide in `RevealSystem`'s import set. - -This changes the public API names of the per-agent functions but preserves -all behaviour and is the faithful way to compile. `RevealSystem` still reads -naturally: `Red::red_get_name(stage)`. - -**Unverified:** whether the resolver is happy with `use X as Y;` where the -flattened public set is large; and whether `agent()`/`names()` etc. (same -name across modules) cause a problem *in RevealSystem* — they should not, -because `RevealSystem` never imports those names (it only imports -`Types::{...}`, `prelude::{...}`, and the seven agents *as aliases*; the -aliased ImportSimple still flat-imports the modules' public fns by name, so -the seven `names`/`personality`/`agent`/etc. **do** collide in -RevealSystem's flattened set). RevealSystem never *calls* those collided -names, so it is harmless for type-checking RevealSystem's own bodies — but if -the loader rejects duplicate flat imports outright (rather than deduping), -RevealSystem would fail to load. The observed loader behaviour -(`already_in` dedup, no error) suggests dedup, not rejection. **This is the -single most likely place to need a fix once a compiler is available** — the -robust fallback is to also prefix `names`/`personality`/`teaches`/`lessons`/ -`agent` per colour (e.g. `red_agent()`), at the cost of more churn. - -### 5. `filterMap` + `Option.map` - -`RevealSystem.generateStageReveal` used -`colors->Array.filterMap(c => getRevealText(...)->Option.map(t => (c, t)))`. -The stdlib *does* provide `option::map_filter` and `option::map`, but they -are **not `pub`** (only `option::unwrap_or` is `pub`), so they cannot be -cross-module imported. Rather than depend on that, I inlined the logic with a -`for` loop + `match` accumulating into a `mut` array — the exact idiom -`option.affine`'s own `cat_options`/`map_filter` use internally: - -``` -let mut agentReveals = []; -for color in colors { - match get_reveal_text(color, fromStage, toStage) { - Some(text) => { agentReveals = agentReveals ++ [(color, text)]; }, - None => {} - } -} -``` - -### 6. Float arithmetic & no string interpolation - -* `Int.toFloat(a) /. Int.toFloat(b) *. 100.0` → `float(a) / float(b) * 100.0`. - There is **no `*.`/`/.`** in AffineScript; `math.affine` uses plain `*`/`/` - on `Float`. `float(n)` is the Int→Float builtin (used by `to_float`, which - is itself not `pub`, so `float` is called directly). -* ReScript template literals `` `${x} ...` `` → `++` concatenation.

The contract is machine-pinned: +*`+qle+`, `+qmul_comm+` and `+qmul_one_r+` are provably absent* — grade +_addition_ must be commutative (the separated-context payoff), but grade +_multiplication need not be_, and the order is inert until a subusage +rule exists. _Remaining (R2 proper):_ functorize `+Soundness+` over +`+SEMIRING+`. +* *The 10th law (`+qmul_zero_l+`) — functorisation audit, 2026-06-13.* +The first boundary draft listed nine laws and excluded `+qmul_zero_l+`. +An adversarial abstract-carrier probe of `+Soundness.v:1022-1028+` +(`+uadd_uscaleZero_r+`, on the live preservation path via +`+hv_subst+`/`+ht_subst+`) showed `+uscale Zero+` leaves +`+qmul zero qe+` *irreducible* without it: the concrete proof only +closed because `+simpl+` computes it on `+|Q|=3+`. So `+qmul_zero_l+` is +required _for the abstraction_ (it joins `+qadd_zero_l+`, already named +for the same simpl-reduction reason) and is now the 10th `+SEMIRING+` +law — discharged axiom-free by `+Quantity.qmul_zero_l+`. +`+qmul_comm+`/`+qmul_one_r+` stay out (reached by neither citation nor +reduction). +* *Diffusion finding (adversarial audit).* `+|Q|=3+` is *not* isolated +at `+q_reassoc+` — the `+Quantity.v+` laws are themselves carrier +enumerations reached independently. So carrier-abstraction requires the +Module-Type lift (each instance supplies its own laws); there is no +single-seam shortcut. +* *Functorisation strategy — Coq generativity, probe-verified +2026-06-13.* Coq module functors are *generative for inductives*: +re-applying `+SyntaxF M+` inside a downstream `+UsageF+` yields a +_different_ `+ty+` (verified — `+probe1+` fails). So the naïve "`each +file is `+Module F (M:SEMIRING)+`, chained by re-application`" is +broken. Two paths share inductives (both probe-verified): *consolidated* +(one functor spanning Syntax+Usage+Typing+Soundness, instantiated once) +or *signature-threaded* (each layer’s instance passed as a module +parameter via a per-layer `+Module Type+`). +* *R2 DONE — consolidated, executed 2026-06-13.* The four chain files +are merged into `+SoloCore.v+` as `+Module SoloCoreF (M : SEMIRING)+`; +`+Include SoloCoreF Linear3+` recovers +`+progress+`/`+preservation+`/`+affine_pres+` *axiom-free* +(`+Print Assumptions+` closed; clean rebuild + CI updated). What made it +near-mechanical: `+Import M+` resolves every operator/law name to +`+M+`’s fields, and `+Local Notation Zero/One+` re-aliases the two +literal tokens (single-token identifiers like `+uadd_uscaleZero_r+` +untouched). Only *five* sites needed real fixes, each where the abstract +carrier no longer computes `+qmul+`/`+qadd+` on literals: `+uscale_one+` +(qmul_one_l), `+uadd_zero_l+` (qadd_zero_l), `+uadd_ushift+` +(qadd_zero_r), the left-annihilation `+qmul zero qe+` in +`+uadd_uscaleZero_r+` (qmul_zero_l — the 10th law), and a +`+qadd_zero_r+`-before-`+congruence+` in `+subst2_lemma+`. +`+Context.v+`/`+ContextProps.v+` (dead branch, kept concrete on +`+Quantity+`) and `+EchoResidue.v+` were repointed to `+SoloCore+`; the +_transparent_ `+Linear3+` (never `+Linear3_Sealed+`) keeps the concrete +re-export compatible. `+SoloCoreF+` is now ready to instantiate at +tropical/affine algebras (R4). +* *R3 DONE — affine layer, executed 2026-06-13.* `+affine_pres+` is no +longer an alias of `+preservation+`. Realisation (the *budget-wrapper*, +chosen over the Affine4-instance and the in-judgement subusage-rule +options): the functor parameter widened to `+ORDERED_SEMIRING+` — the +linear proofs still cite only `+SEMIRING+`, so they are untouched and +stay axiom-free. `+ule+` = pointwise `+qle+`; +`+aff_type G D t a := ∃ D0, has_type G D0 t a ∧ ule D0 D+` ("`uses at +most budget `+D+``"). `+has_type_aff+` embeds linear ⊆ affine; +`+aff_weaken+` relaxes the budget upward (the affine _discard_ a +strictly-linear system forbids); `+AffinePreservation+` (budget-stable +preservation) is proved axiom-free by riding the linear `+preservation+` +at the realised usage. `+Quantity.qle_trans+` was added and +`+ORDERED_SEMIRING+` is now a live preorder +(`+qle_refl+`/`+qle_trans+`/`+qle_zero+`). The Affine4 4-point semiring +stays available through the same functor as a future R4 instance. +* *R5 DONE — verified usage-walk checker, executed 2026-06-13.* The +static context-splitting judgement `+has_type+` is proved equivalent to +an EXECUTABLE one-pass synthesiser +`+check : tctx → tm → option (ty × uvec)+`: `+check_sound+` (only +well-typed terms accepted), `+check_complete+` (every derivation +recovered with EXACTLY its usage — usage determinacy internalised, +corollary `+typing_unique+`), and +`+check_correct : has_type G D t a ↔ check G t = Some (a, D)+` — all +real `+Qed+`, axiom-free (`+Print Assumptions+` closed, CI-guarded). The +calculus is synthesis-directed (every former carries its annotations), +so a single bottom-up walk decides typing; it needs only `+Q_eq_dec+` +(added to `+ORDERED_SEMIRING+`, discharged by both instances), which the +soundness proofs do not. `+Module SoloTropical := SoloCoreF Tropical+` +inherits the verified checker at the INFINITE min-plus carrier for free +(R4-style acceptance test). This is the F1.4 tail and *overtakes +AffineScript*, whose solo-core states the same static-split≡usage-walk +equivalence only as prose ("`an explicit equivalence lemma is future +work`"). The checker decides the strictly-LINEAR `+has_type+`; the +affine _discard_ (`+aff_type+`/`+ule+`, R3) is a separate budget layer, +now also decided — *R5b DONE:* `+ule_dec+` (the budget order), +`+aff_type_iff+` (the `+check+`-characterisation +`+aff_type G D t a ↔ ∃ D0, check G t = Some (a, D0) ∧ ule D0 D+`) and +`+aff_type_dec+` (decidability of the affine judgement) are axiom-free +and inherited free at the tropical carrier too. Several +`+Compute+`-backed examples pin non-vacuity: a linear binder used once +is accepted; one dropped (usage `+Zero+`) or duplicated multiplicatively +(usage `+Omega+`) is rejected — the latter accepted under an `+Omega+` +binder, so the rejection is exactly the linearity check. The affine +_discard_ is the precise separator: the SAME `+UnitT+` at budget `+One+` +is `+aff_type+`-accepted (realises `+Zero ≤ One+`) yet +`+has_type+`-rejected. +* *M1 DONE (partial) — me→solo elaboration adequacy, axiom-free +2026-06-14.* The visual / block `+me+` surface (`+proofs/me/+`, no +settled AST in code — only the paper block grammar in +`+visual-semantics/formal-model.md+`) is pinned as a Coq `+me_tm+` (the +affine/token fragment) with `+elab : me_tm → tm+` landing in the de +Bruijn solo core — the mechanised analogue of the paper `+translate+` +(which targets Rust-ish surface syntax and is never mechanised). *M1.0:* +`+Example+`s execute `+elab+` + the R5 `+check+` on the concrete carrier +(linear token create-and-consume accepted; the dropped token rejected +linearly but accepted via sequencing and via the R3 `+aff_type+` layer; +the echo linear→affine bridge end-to-end). *M1.1:* the UNIVERSAL +adequacy theorem +`+elab_data_check : ∀ e G, me_data e = true → ∃ a, check G (elab e) = Some (a, uzero G)+` +(formal-model.md Theorem 1, Visual Soundness) for the no-linear-use +fragment (data + discard-sequencing + injections), with corollaries +`+elab_data_typed+` (`+has_type+` via `+check_correct+`) and +`+elab_data_aff_budget+` (fits any affine budget ≥ `+uzero G+`).

So - `qmul_zero_l` is required *for the abstraction* (it joins `qadd_zero_l`, already named for - the same simpl-reduction reason) and is now the 10th `SEMIRING` law — discharged - axiom-free by `Quantity.qmul_zero_l`. `qmul_comm`/`qmul_one_r` stay out (reached by - neither citation nor reduction). -- **Diffusion finding (adversarial audit).** `|Q|=3` is **not** isolated at `q_reassoc` — - the `Quantity.v` laws are themselves carrier enumerations reached independently. So - carrier-abstraction requires the Module-Type lift (each instance supplies its own laws); - there is no single-seam shortcut. -- **Functorisation strategy — Coq generativity, probe-verified 2026-06-13.** Coq module - functors are **generative for inductives**: re-applying `SyntaxF M` inside a downstream - `UsageF` yields a *different* `ty` (verified — `probe1` fails). So the naïve "each file is - `Module F (M:SEMIRING)`, chained by re-application" is broken. Two paths share inductives - (both probe-verified): **consolidated** (one functor spanning Syntax+Usage+Typing+Soundness, - instantiated once) or **signature-threaded** (each layer's instance passed as a module - parameter via a per-layer `Module Type`). -- **R2 DONE — consolidated, executed 2026-06-13.** The four chain files are merged into - `SoloCore.v` as `Module SoloCoreF (M : SEMIRING)`; `Include SoloCoreF Linear3` recovers - `progress`/`preservation`/`affine_pres` **axiom-free** (`Print Assumptions` closed; clean - rebuild + CI updated). What made it near-mechanical: `Import M` resolves every operator/law - name to `M`'s fields, and `Local Notation Zero/One` re-aliases the two literal tokens - (single-token identifiers like `uadd_uscaleZero_r` untouched). Only **five** sites needed - real fixes, each where the abstract carrier no longer computes `qmul`/`qadd` on literals: - `uscale_one` (qmul_one_l), `uadd_zero_l` (qadd_zero_l), `uadd_ushift` (qadd_zero_r), the - left-annihilation `qmul zero qe` in `uadd_uscaleZero_r` (qmul_zero_l — the 10th law), and a - `qadd_zero_r`-before-`congruence` in `subst2_lemma`. `Context.v`/`ContextProps.v` (dead - branch, kept concrete on `Quantity`) and `EchoResidue.v` were repointed to `SoloCore`; the - *transparent* `Linear3` (never `Linear3_Sealed`) keeps the concrete re-export compatible. - `SoloCoreF` is now ready to instantiate at tropical/affine algebras (R4). -- **R3 DONE — affine layer, executed 2026-06-13.** `affine_pres` is no longer an alias of - `preservation`. Realisation (the **budget-wrapper**, chosen over the Affine4-instance and the - in-judgement subusage-rule options): the functor parameter widened to `ORDERED_SEMIRING` — - the linear proofs still cite only `SEMIRING`, so they are untouched and stay axiom-free. - `ule` = pointwise `qle`; `aff_type G D t a := ∃ D0, has_type G D0 t a ∧ ule D0 D` ("uses at - most budget `D`"). `has_type_aff` embeds linear ⊆ affine; `aff_weaken` relaxes the budget - upward (the affine *discard* a strictly-linear system forbids); `AffinePreservation` - (budget-stable preservation) is proved axiom-free by riding the linear `preservation` at the - realised usage. `Quantity.qle_trans` was added and `ORDERED_SEMIRING` is now a live preorder - (`qle_refl`/`qle_trans`/`qle_zero`). The Affine4 4-point semiring stays available through the - same functor as a future R4 instance. -- **R5 DONE — verified usage-walk checker, executed 2026-06-13.** The static - context-splitting judgement `has_type` is proved equivalent to an EXECUTABLE - one-pass synthesiser `check : tctx → tm → option (ty × uvec)`: `check_sound` - (only well-typed terms accepted), `check_complete` (every derivation recovered - with EXACTLY its usage — usage determinacy internalised, corollary - `typing_unique`), and `check_correct : has_type G D t a ↔ check G t = Some (a, D)` - — all real `Qed`, axiom-free (`Print Assumptions` closed, CI-guarded). The - calculus is synthesis-directed (every former carries its annotations), so a single - bottom-up walk decides typing; it needs only `Q_eq_dec` (added to - `ORDERED_SEMIRING`, discharged by both instances), which the soundness proofs do - not. `Module SoloTropical := SoloCoreF Tropical` inherits the verified checker at - the INFINITE min-plus carrier for free (R4-style acceptance test). This is the F1.4 - tail and **overtakes AffineScript**, whose solo-core states the same - static-split≡usage-walk equivalence only as prose ("an explicit equivalence lemma - is future work"). The checker decides the strictly-LINEAR `has_type`; the affine - *discard* (`aff_type`/`ule`, R3) is a separate budget layer, now also decided — - **R5b DONE:** `ule_dec` (the budget order), `aff_type_iff` (the `check`-characterisation - `aff_type G D t a ↔ ∃ D0, check G t = Some (a, D0) ∧ ule D0 D`) and `aff_type_dec` - (decidability of the affine judgement) are axiom-free and inherited free at the - tropical carrier too. Several `Compute`-backed examples pin non-vacuity: a linear - binder used once is accepted; one dropped (usage `Zero`) or duplicated - multiplicatively (usage `Omega`) is rejected — the latter accepted under an `Omega` - binder, so the rejection is exactly the linearity check.

Makes `affine_pres` **DISTINCT** from `preservation` (no longer `:= Preservation`). The linear proofs use only `SEMIRING`. | -| Tropical (min-plus) instance | Coq `solo-core/Tropical.v` | **machine-checked** | **R4 (2026-06-13).** `Module Tropical <: ORDERED_SEMIRING` (carrier ℕ∪{∞}, ⊕=min, ⊗=+, 0=∞, 1=Fin 0); `Module SoloTropical := SoloCoreF Tropical` yields `progress`/`preservation`/`affine_pres` **axiom-free at an INFINITE carrier** with no new soundness proof — the R2 functor's acceptance test (it provably does not rely on the finite carrier). | -| Usage-walk checker (`check`) + adequacy | Coq `solo-core/SoloCore.v` | **machine-checked** | **R5 (2026-06-13).** Executable one-pass synthesiser `check : tctx → tm → option (ty × uvec)` proved equivalent to the declarative `has_type`: `check_sound` (only well-typed terms accepted), `check_complete` (every derivation recovered with **exactly** its usage), and `check_correct : has_type G D t a ↔ check G t = Some (a, D)` are real `Qed`, **axiom-free** (`Print Assumptions` closed, CI-guarded). Internalises usage/type determinacy (corollary `typing_unique`). `SoloTropical` inherits the verified checker at the **infinite** carrier for free. Needs `Q_eq_dec` (added to `ORDERED_SEMIRING`); the soundness proofs do not. The F1.4 tail; **overtakes AffineScript** (which states the same static-split≡usage-walk equivalence only as prose — "an explicit equivalence lemma is future work"). Several `Compute`-backed examples pin non-vacuity. | -| Affine judgement decidability (`aff_type_dec`) | Coq `solo-core/SoloCore.v` | **machine-checked** | **R5b (2026-06-13).** `check` decides the strictly-**linear** `has_type`; the **affine** judgement `aff_type` (R3, the affine *discard*) is decided by `aff_type_dec`, via `aff_type_iff : aff_type G D t a ↔ ∃ D0, check G t = Some (a, D0) ∧ ule D0 D` (the affine analogue of `check_correct`) and `ule_dec` (the budget order is decidable as `qle` is `bool`). All axiom-free, CI-guarded, inherited free at the tropical carrier. The discard is the exact separator: the same `UnitT` at budget `One` is `aff_type`-accepted but `has_type`-rejected. | -| `me → solo` elaboration (`elab`) + concrete adequacy | Coq `solo-core/SoloCore.v` | **machine-checked** | **M1.0 (2026-06-14).** The visual/block `me` surface (no settled AST in code — only the paper block grammar in `proofs/me/visual-semantics/formal-model.md`) is pinned as `me_tm` (the affine/token fragment) with `elab : me_tm → tm` landing in the de Bruijn solo core (the mechanised `translate`). `Example`s EXECUTE `elab` + the R5 `check` on the concrete carrier: a linear token create-and-consume is accepted; the dropped token is rejected linearly but accepted via sequencing and via the R3 `aff_type` layer; the echo linear→affine bridge end-to-end. Real `Qed`/`reflexivity`. | -| `me → solo` universal adequacy (`elab_data_check`) | Coq `solo-core/SoloCore.v` | **machine-checked** | **M1.1 (2026-06-14).** `elab_data_check : ∀ e G, me_data e = true → ∃ a, check G (elab e) = Some (a, uzero G)` — formal-model.md Theorem 1 (Visual Soundness) for the no-linear-use fragment (data + discard-sequencing + sum injections), real `Qed`, **axiom-free** (`Print Assumptions` closed, CI-guarded). Corollaries `elab_data_typed` (`has_type` via `check_correct` — the cleanest Visual-Soundness statement) and `elab_data_aff_budget` (fits any affine budget ≥ `uzero G`, the R3 discard). The first mechanised surface→core elaboration-correctness result in either sibling; **overtakes AffineScript** (solo-only, no `me`-like dialect). The linear-USE constructs are M1.0 `Example`s here; their UNIVERSAL adequacy is **M1.1b** (below). | -| `me → solo` universal linear-use adequacy (`me_wt` / `me_wt_sound`) | Coq `solo-core/SoloCore.v` | **machine-checked** | **M1.1b (2026-06-14).** A me-level typing/usage judgement `me_wt : tctx → uvec → me_tm → ty → Prop` (the visual linear token discipline, colours/ports abstracted) with `me_wt_sound : me_wt G D e a → has_type G D (elab e) a` — elaboration is type- AND usage-preserving — real `Qed`, **axiom-free** (`Print Assumptions` closed, CI-guarded). Covers the resource-INTERESTING constructs UNIVERSALLY: token consumption (`MeVar`), `MeLet` (consumed once), `MeUsePair`, and the new faithful conditional `MeIf → Case` (the paper IfBlock = sum ELIM; `MeInl`/`MeInr` are sum INTRO). Corollaries `me_wt_check` (accepted by the verified `check`) and `me_wt_aff` (any affine budget ≥ realised usage). It spans the WHOLE `me_tm`: `MeSeq` (sequencing/discard) is closed too via `MW_Seq`, reusing the existing F1.4 `ht_shift0` weakening lemma (e1 erased at multiplicity Zero, e2 weakened under the discarded binder) — so the elaboration is universally type- and usage-preserving over the entire pinned surface. **M1 (axis-4 SURFACE) is complete.** | -| Ensemble session-π core (`SessionPi.v`) | Coq `solo-core/SessionPi.v` | **definitions-only** (+ machine-checked witnesses) | **S1.0 (axis-2 STRUCTURE, 2026-06-14).** A NEW standalone Coq development (NOT an extension of `SoloCore.v` — processes are a different term language; nothing carrier-bearing imported) for the ensemble session-typed π-calculus, after `proofs/duet/session-types/` + `proofs/ensemble/agent-calculus/`. Defines: base-value payloads (`vty`/`val`/`vtype`), session types `sty` (send/recv/end) with a computed duality and `dual_involutive` (`Qed`), polarised endpoints (`Pos`/`Neg`, `co_involutive`), processes `proc` (nil/send/recv/par/νrestriction), capture-safe payload substitution, a **linear** channel-typing judgement `wt` with context splitting `csplit`, and small-step `step` for the communication redex under par/ν contexts. Executable witnesses are real `Qed`: a **well-typed ping-pong** (`wt_pingpong`) that **reduces** (`step_pingpong`/`step_sys`), plus duality `Compute` examples — all **axiom-free** (`Print Assumptions` closed), CI-built by `proofs.yml`. **Subject reduction is NOT claimed here** — it is the S1.1 obligation. Honest OUT (deferred): name-passing/mobility (payloads are base values ⇒ capture-safe, no scope extrusion), structural congruence (S1.2), choice select/branch (S1.2), replication, mismatch, μ-recursion, bisimulation, the AI primitives, and multiparty `G`/projection (the S2 hook). | -| Session-π **communication-redex** subject reduction (`sr_comm`) + value substitution (`wt_subst`) | Coq `solo-core/SessionPi.v` | **machine-checked (Coq)** | **S1.1a (2026-06-14).** The load-bearing core of subject reduction, isolated as two axiom-free `Qed` lemmas (`Print Assumptions` closed, CI-guarded). `wt_subst` (with corollary `wt_subst0`) is the **first-order value-substitution lemma** — strictly easier than the solo core's `ht_subst` because payloads are base values (no channel-context splitting inside the substitution). `sr_comm` is **subject reduction for R-Comm**: given a sender continuing at `k` and a receiver that — by DUALITY (exactly what a ν-bound channel guarantees) — expects the sent type `t` and continues at `dual k`, the reduct `P ∣ Q[v]` is well-typed at the session-**advanced** context. These are architecture-invariant (they act at the payload / `PPar` level, never touching the ν binder). | -| Session-π **full closed-system** subject reduction (`config_subject_reduction`) | Coq `solo-core/SessionPi.v` | **machine-checked (Coq)** | **S1.1b (2026-06-14).** `config_subject_reduction : wf_config c → cstep c c' → wf_config c'` — real `Qed`, **axiom-free** (`Print Assumptions` closed, CI-guarded). Done via the **fused two-party `(νc)(P∣Q)` form** (`config`/`party`/`cstep`, the duet T-Session primitive — owner-chosen): the shared protocol lives on the configuration and **advances locally** on each communication, so the free context never changes and ν re-typing is automatic (the protocol `s` is existential in `wf_config`). Reuses the S1.1a value-substitution machinery verbatim via the party analogue `pty_subst`/`pty_subst0`. Faithfulness fence: the TWO-PARTY, SINGLE-SESSION, straight-line fragment (each party sequential send/recv/end on its one endpoint; no intra-party parallelism, sub-session nesting, free channels, or choice — richer structure stays with the open `proc` calculus, whose R-Comm case is `sr_comm`). Witness `wf_preserved_pingpong` instantiates it end-to-end. | -| Session-π **session fidelity** + **progress / deadlock-freedom** (`session_fidelity`, `config_progress`) | Coq `solo-core/SessionPi.v` | **machine-checked (Coq)** | **S1.2 (2026-06-14).** The duet paper's headline SAFETY and LIVENESS theorems for the binary send/recv/end fragment, both real `Qed`, **axiom-free** (`Print Assumptions` closed, CI-guarded). `session_fidelity`: a communication advances the shared protocol by EXACTLY one `sty_step` (head action consumed) and the reduct is well-formed at that successor — the reduction follows the session type (refines subject reduction by pinning *which* protocol the reduct follows). `config_progress`: a well-formed config is either fully ended (`Conf QEnd QEnd`) or can step — no stuck/deadlocked state, since duality matches each party's pending action with the other's dual. Still OUT (S1.3+): internal/external choice (select/branch), μ-recursion, structural congruence over the open `proc` calculus, and multiparty `G`/projection (the S2 hook). | -| Session-π **choice** (select/branch ⊕/&) — `config_subject_reduction` / `session_fidelity` / `config_progress` extended | Coq `solo-core/SessionPi.v` | **machine-checked (Coq)** | **S1.3a (axis-2 STRUCTURE, 2026-06-14).** **n-ary, labelled** internal/external choice (the paper's `⊕/&{lᵢ:Sᵢ}`, formal-system.md:81-88/182), all real `Qed`, **axiom-free** (`Print Assumptions` closed, CI-gated). `sty`/`party` gain `SSelect`/`SBranch`/`QSel`/`QBra` over **dedicated mutual inductives** `sbranch`/`pbranch` (NOT `list (nat*_)`, so `dual` and `psubst_party` are well-guarded mutual fixpoints — Coq's guard checker rejects the `List.map` form). Duality dualises **pointwise over the label list preserving labels**; `pty` carries label-coverage premises (via the functional lookups `bget`/`pget`), so **label-mismatch safety is expressible** — a select on an unoffered label is ill-typed. The three S1.1b/S1.2 theorems are extended with the choice cases (`sty_step` gains `SS_Sel`+`SS_Bra` and is now non-deterministic — the chosen label is threaded through fidelity); `pty_subst` is reproved over the **mutual `party_mut` scheme** so its `QBra` case recurses structurally into branches. Witnesses: a 2-branch `{0:end,1:end}` choice that is well-formed, steps (`CSel`), and is deadlock-free. **Fence:** still TWO-PARTY fused form. **Faithfulness note:** the panel-flagged binary alternative was rejected — n-ary is required so S2.2's `merge` (over label sets) is statable. Echo-types audit: **NOT-RELEVANT** (axis-2 STRUCTURE). | -| Session-π **structural congruence preserves typing** (`wt_congr`) | Coq `solo-core/SessionPi.v` | **machine-checked (Coq)** | **S1.3c (axis-2 STRUCTURE, 2026-06-14).** On the OPEN `proc` calculus, `wt_congr : wt G D P → cong P Q → wt G D Q` — structural congruence preserves the linear channel-typing, real `Qed`, **axiom-free** (CI-gated). Proved as an iff (`wt_congr_iff`) so the symmetric closure goes through in one induction. `cong` = the three **par laws** `P\|0≡P`, `P\|Q≡Q\|P`, `(P\|Q)\|R≡P\|(Q\|R)` (full equivalence). New context-splitting algebra: `csplit_comm`, `csplit_assoc` (reassociation — load-bearing), `csplit_ended`, and **`wt_absorb_ended`** (the par-nil engine: ended endpoints thread through the typing derivation to the `PNil` leaves; by induction on `wt`). **Honest fence:** this is typing-PRESERVATION under ≡, **NOT** subject-reduction-up-to-≡ (no reduction in the statement — the open form lacks closed SR for the S1.1b ν reason). OUT (named, with reasons): **ν-extrusion** (needs a free-name function `fn` that does not exist → side-condition unstatable), **ν-swap** (needs an absent context-permutation lemma), **replication** `*P≡P\|*P` (no `!P` constructor → vacuous). Echo-types audit: **NOT-RELEVANT** (axis-2 STRUCTURE). | -| Session-π **μ-recursion — type layer** (`unfold_mu`, `dual_unfold`, `guarded`) | Coq `solo-core/SessionPi.v` | **machine-checked (Coq), PARTIAL** | **S1.3b-core (axis-2 STRUCTURE, 2026-06-14).** The equi-recursive **type-layer** infrastructure (the S2.2 projection target), all real `Qed`, **axiom-free** (CI-gated). `sty` gains `SMu`/`SVar` (de Bruijn); `tlift`/`tsubst` (mutual over `sty`/`sbranch`) and **`unfold_mu (μa.s) := s[μa.s/a]`** — a plain `Definition`, ONE structural `tsubst` pass, so it terminates with **no fuel/measure even on `μa.a`**. `dual` passes through `SMu`/`SVar` untouched (correct ONLY because recursion variables are **unpolarised** — fenced). **`dual_unfold : dual (unfold_mu s) = unfold_mu (dual s)`** — the projection-duality-of-recursion lemma S2.2 consumes (via `dual_tlift`/`dual_tsubst`). **`guarded`** — a depth-indexed contractiveness predicate (every `SVar` referring to an inner μ-binder occurs under a message/choice prefix; carried in WELL-FORMEDNESS, never in typing); witnessed: `μa.!Nat.a` is guarded, `μa.a` is not.

The **head** select/branch sanctioned by a head `GBra p q {lᵢ:Gᵢ}` carries wf from `G` to its **selected** branch continuation `Gl = gbget l bs`: **`nstep_sr_choice_head : p≠q → gbget l bs = Some Gl → wf_assignment_f (GBra p q bs) ra → ra_get ra p = Some (QSel l P) → ra_get ra q = Some (QBra bsP) → pget l bsP = Some Q → wf_assignment_f Gl (ra_set (ra_set ra p P) q Q)`**.

The label `l` drives BOTH the new global step (**`GStep_Bra`** on the new functional gbranch lookup **`gbget`** — no such lookup pre-existed; only `proj_br`/`proj_uninv` consumed `gbranch`) and the located **`NStep_Sel`** onto the **SAME** `Gl`. **The genuinely-new part vs the message head:** the uninvolved arm is no longer **definitional** — it rides `proj_uninv` (the plain-merge fold over all branches) and is discharged by the new **`proj_uninv_selected`** via **`merge_forces_eq`** (plain merge is the IDENTITY-MEET, so every branch projects an uninvolved `r` to the SAME type, hence so does the selected `Gl`; the ≥2-branch case uses an explicit one-level unfold to avoid `cbn [proj_uninv]` over-unfolding). The coupled corollary **`nstep_gstep_sr_choice_head`** packages `gstep`+`nstep`+`wf'` for the head step. **Non-vacuity:** `choice3_head_fires_end_to_end` fires the rung end-to-end on the agreeing 3-party choice `g_choice3` (+ `wf_ra_choice3`). **Honest fences:** (1) **HEAD choice only** — run-ahead/non-head selection = S3c.3-perm (a non-head has no matching head `GStep_Bra`); (2) **PLAIN `proj`** (not `proj_u`) — the uninvolved arm leans on `merge_forces_eq`=identity-meet; the label-UNION merge is S3 (**regression pin**: widening `merge` breaks `proj_uninv_selected` and this theorem becomes false-as-stated — that IS the S3 fence); (3) coupled corollary is a head **wrapper** for ONE step, NOT general SR/bisimulation; (4) `p≠q`-as-hypothesis + **functional** `wf_assignment_f` inherited; (5) **PRESERVATION only** — NO progress (S3c.4).

Strictly **ADDITIVE** (bytes 1-2868 SHA-identical to baseline; sole prior-region edit = the `gbget` fixpoint + the `GStep_Bra` constructor on the `gstep` Inductive). **Remaining S3c (solo):** S3c.3-perm (run-ahead), S3c.4 n-party progress (research-hard — fence).

Mirrors the Coq twin `preservation`: the β/projection/elimination cases consume the QTT substitution lemmas from `Substitution.idr` — `substLemma0` (App/Case/Let single-variable) and `subst2Lemma` (LetPair two-variable) — realigning the residual usage with `d` via `uadd` commutativity/associativity (`uaddAssoc`) and `uscale One`; congruence cases recurse structurally. Stated over the CORRECT design (separated context + genuine products) that made the same-usage statement sound (issue #93). The reduct term `t` is taken explicitly (relevant), exactly as `progress` does, because Idris erases the derivation's term/type indices while the substitution lemmas compute on the bound body + substituted value. `affinePreservation` follows as the Solo-kernel corollary (`:total` too).

The `b`-index-erasure obstruction (ADR-003) is resolved by carrying `b` erased. `idris2 --build solo-core.ipkg` exits 0; **the solo core is now HOLE-FREE**.

The former PENDING prose sketch in `ResourceAlgebra.v` is now the real **`Module Type RESIDUE_MEASURE (S : SEMIRING)`** — `measure : Residue → S.Q` with `measure_empty`/`measure_combine` (a monoid homomorphism `(Residue,combine,empty) → (S.Q,qmul,one)`, needing only the DONE R2 SEMIRING) — a faithful mirror of the upstream `tropical-resource-typing` `Resource/EchoBridge.lean` `structure ResidueMeasure`. `EchoMeasure.v` **inhabits** it at the DONE R4 Tropical cost carrier (`EchoTraceTropical`: a residue is an echo reindexing trace, `measure` = accumulated `Affine`-collapse cost = tropical `Fin`), and witnesses measure-**independence** on the Coq side via **`echo_measure_not_injective`** (`[Affine]` and `[Linear;Affine]` both cost `Fin 1` → the measure cannot reconstruct the residue). **Echo-types audit: RELEVANT (axis-3 ECHO)** — the audit confirmed the seam is already mechanised upstream on both foundations (echo-types `Echo/Measure/Interface.agda` `ResidueMeasure` + `Separation/NotResourceInstance.agda` `equal-measure-does-not-imply-equal-echo`, `--safe --without-K`); per the audit directive the Coq side **reuses** rather than re-derives. **Honest fences:** (1) the Coq mirror carries the measure HOMOMORPHISM + residue-level non-injectivity; the full measure-independence over the degrade-compose modality (the `ECHO_MODALITY` `act` transport, sketch (b)) is upstream-**CITED**, not re-derived — hence the ladder marks E4 `◑` (Coq mirror ✓, full seam upstream); (2) **hard IS-NOT invariant kept** — Echo is NOT a resource/SEMIRING instance, `measure` is a one-directional `E→R` lossy decoration, and `EchoMode.v`/`EchoResidue.v` stay `Quantity`-independent; (3) the trace carrier is the **free** residue monoid (the minimal composition skeleton), not a claim to BE the full echo residue object. | - -## Paper proofs (`proofs/**.md`) - -| Area | Status | Location | -|------|--------|----------| -| Type-system soundness | proved-on-paper | `proofs/shared/type-system/soundness.md` | -| Type-system metatheory / inference / subtyping | proved-on-paper | `proofs/shared/type-system/` | -| Effect-system soundness | proved-on-paper | `proofs/shared/effect-system/soundness.md` | -| Memory model / ownership | proved-on-paper | `proofs/shared/memory-model/ownership.md` | -| Operational & denotational semantics | proved-on-paper | `proofs/shared/{operational,denotational}-semantics/` | -| Solo affine types | proved-on-paper | `proofs/solo/affine-types/formal-system.md` | -| Duet session types | proved-on-paper | `proofs/duet/session-types/formal-system.md` | -| Ensemble agent calculus | proved-on-paper | `proofs/ensemble/agent-calculus/` | -| AI semantics | proved-on-paper | `proofs/shared/ai-semantics/` | - -## Gaps vs AffineScript (see ALIGNMENT-PLAN.md §3) - -| Topic AS has | my-lang status | Plan phase | -|--------------|----------------|-----------| -| Mechanised QTT solo-core | **commenced** (this PR) | F1 | -| Mechanised progress/preservation | Coq **machine-checked** (axiom-free `Qed`, CI-guarded); Idris twin **locally-checked** (both total + hole-free; `preservation` #108 discharged 2026-06-21) | F1.3 / F1.4 | -| Algorithmic typing / decidable typecheck (static-split ≡ usage-walk) | Coq **machine-checked** (`check_correct`, axiom-free) — **overtakes AS** (states it as prose "future work" only) | F1.4 | -| Surface→core elaboration correctness (`me` → `solo`) | Coq **machine-checked** (`me_wt_sound` over the WHOLE `me_tm` + `elab_data_check`, axiom-free, M1.1/M1.1b — M1 complete) — **overtakes AS** (solo-only; no `me`-like dialect, nothing analogous as surveyed (AS@main 2026-06-02)) | M1 | -| Quantitative-types (dedicated doc) | folded into solo affine doc | F4 | -| Row-polymorphism proof | absent | F4 | -| Dependent/refinement types proof | absent | F4 | -| Axiomatic (Hoare) semantics | absent | F4 | -| Categorical semantics | absent | F4 | -| Complexity analysis | absent | F4 | -| Proof CI leg | **present** — `proofs.yml` machine-checks both tracks (`coqc` + `idris2 --build`); overtakes AS | F5 | - -## Implementation ⇄ spec coupling (status: #1–#4 **closed**, #5 **by-design**, 2026-06-21) - -The mechanised cores above are the **spec**; the Rust toolchain -(`crates/my-lang`) is a separate, conventional AI-first implementation.

SCOPE/honesty: this is differential refinement-by-conformance against the *extracted verified algorithm*, NOT a full Rust-in-Coq refinement proof; and the *main* `crates/my-lang/src/checker.rs` (Hindley) now CALLS the verified core by default for `#[safe]` functions (`Checker::check_qtt_safe_fn` → `qtt_bridge` → `my_qtt::check`; a dropped/duplicated binder in the resource fragment is a `CheckError::ResourceViolation`, out-of-fragment bodies skip). So the resource axis is enforced-by-default where opted in via `#[safe]` (the `docs/STATUS.adoc` "make the resource axis the default" item — DONE); whole-program linear-by-default is intentionally NOT the design (my-lang is not a linear language). | -| Evaluator refines Coq `step` (solo core) | **conformance-checked** | **CLOSED 2026-06-21.** The reference semantics is the `step` RELATION (not extractable), so `Eval.v` adds a FUNCTIONAL `step1 : tm -> option tm` and proves it both ways vs the relation — `step1_sound : step1 t = Some t' -> step t t'` and `step1_complete : step t t' -> step1 t = Some t'` — real `Qed`, **axiom-free** (`Print Assumptions` closed), machine-checked in CI (`Eval.v` is in `_CoqProject`). `step1` is extracted alongside `check` (Extract.v) and the Rust port `my_qtt::step1` (faithful `shift`/`subst_at`/`subst0`/`subst2`/`is_value`/`step1`) is differentially conformance-tested against it: `conformance/run.sh` compares **one-step** results AND **iterated normal forms** (cap 64) over a random + closed-redex corpus. **45 000 results across 5 seeds agree** (3000 terms × {check, one-step, normal-form}); the normal-form pass cross-checks the Rust substitution against Coq's extracted `subst`. SCOPE/honesty: this couples an evaluator over the SHARED solo `tm` (the same approach as the checker), exactly mirroring `step`; the separate AI-surface `interpreter.rs` (richer term language, runtime no-ops for `Restrict`/`Ref`/`RefMut`) is NOT what is coupled here and remains an independent, unverified frontend. | -| Echo modality wired into surface + checker | **conformance-checked** (verified-core surface) | **2026-06-21.** Echo is wired end-to-end through the VERIFIED core: the `my_qtt::surface` fragment has echo intro (`SExpr::Echo` / `STy::Echo`) and the `weaken` elimination (`SExpr::Weaken`), `elaborate` lowers them to `Tm::MkEcho`/`Tm::Weaken`, and the machine-checked `check` consumes them — so the `linear ⊑ affine` discipline (`EchoLinear`) is enforced from a surface term by the proof. Pinned by `surface.rs` tests: intro types correctly, a LINEAR echo `weaken`s to AFFINE, weakening an AFFINE echo is REJECTED (the one-way *no-section* fact), and witness linearity is threaded (an echo whose witness drops a linear binder is rejected). Echo terms are also in the random differential-conformance corpus (#1/#2), so `my_qtt`'s echo handling matches the extracted Coq `check`/`step1`. SCOPE/honesty: this closes echo on the verified-core-facing surface; the *conventional compiler* (`crates/my-lang` `ast::Expr`/parser) still has no echo SYNTAX (so `qtt_bridge` cannot yet lower a compiler-AST echo — that needs a type-annotated echo grammar, a frontend follow-on like the `Param` quantity syntax). `types.rs` `EchoMode` is no longer inert at the verified boundary; it is in the conventional frontend. | -| Session runtime refining `cstep` / `nstep` / `gstep` (all three layers) | **conformance-checked** | **2026-06-21.** `SessionEval.v` adds a functional stepper for each layer of the session metatheory and proves it adequate vs the reference RELATION, all real `Qed`, **axiom-free**, in `_CoqProject` (CI-gated): (1) **binary** `cstep1 : config -> option config` — SOUND + COMPLETE vs `cstep`; (2) **global** `gstep1 : gty -> option gty` — SOUND + PROGRESS vs `gstep` (`gstep1_sound` + `gstep1_complete`, the progress form because `gstep` is nondeterministic at `GBra`); (3) **n-ary located** `nstep1 : role_assignment -> option role_assignment` — SOUND + PROGRESS vs `nstep` (`nstep1_sound` + `nstep1_complete`; `nstep1` scans for the first communicating pair via `find_recv`/`find_bra`, parties always re-fetched through `ra_get`). All three are extracted (Extract.v) and the Rust runtime `my_qtt::session` (faithful `val`/`party`/`config`/`gty`/`role_assignment` + the substitution/lookup chain + `cstep1`/`gstep1`/`nstep1`) is differentially conformance-tested against them (`conformance/run.sh`, `(cstep …)`/`(gstep …)`/`(nstep …)` queries) — **90 000 results across 5 seeds agree** (6 query classes × 3000 cases × 5 seeds). SCOPE/honesty: for the two NONDETERMINISTIC relations the functional stepper commits to a deterministic strategy (first branch / first pair), so adequacy is soundness + progress (`step1 = None` iff the relation is stuck), NOT functional determinism — the honest statement for a nondeterministic reduction. The AI-surface `interpreter.rs` (`Go`/`Await` collapse to sequential) is a separate unverified frontend. | -| Concrete `me` surface exercising the M1 elaboration | **by-design — not a gap** | **Affirmed 2026-06-21.** This is a deliberate architectural decision, NOT an omission: `Me` is an on-the-fly agent-generated *runtime projection* over the `Solo ⊂ Duet ⊂ Ensemble` dialect hierarchy, **not** a static fourth dialect — two attempts to build it as a static compiler were retired (`hyperpolymath/me-dialect` archived; in-tree `dialects/me/` sidelined to `_exploratory/me-scaffolding/SIDELINED.adoc`). The elaboration coupling that DOES matter is already machine-checked: M1 (`me_wt_sound`) proves `me -> solo` adequacy over the abstract Coq `me_tm`, axiom-free.

Effect union -is O(|Effects|) which is bounded by a constant. □ - -## Relationship to Other Type Systems - -### Hindley-Milner (System F₁) - -My Language's core is an extension of Hindley-Milner: - -| Feature | HM | My Language | -|---------|-----|-------------| -| Let-polymorphism | ✓ | ✓ | -| Type inference | ✓ | ✓ | -| Principal types | ✓ | ✓ | -| Higher-rank types | ✗ | Partial | -| Subtyping | ✗ | ✓ | -| Effects | ✗ | ✓ | -| AI types | ✗ | ✓ | - -### System F (Second-order λ-calculus) - -For explicit type annotations, we support System F features: - -- Universal quantification (∀α. τ) -- Type application (e[τ]) -- Impredicative instantiation (limited) - -### System Fω (Higher-kinded types) - -Planned extension for type-level computation: - -- Type constructors (F : * → *) -- Higher-kinded polymorphism (∀F: * → *. ...) - -### Linear/Affine Types - -The Solo dialect extends with affine types: - -- Affine type: τᵃ (use at most once) -- Linear type: τˡ (use exactly once) - -See [../../../solo/affine-types/](../../../solo/affine-types/). - -### Session Types - -The Duet dialect incorporates session types: - -- Session type: S ::= !τ.S | ?τ.S | S ⊕ S | S & S | end - -See [../../../duet/session-types/](../../../duet/session-types/). - -## Normalization - -### Strong Normalization (Simply-Typed Fragment) - -**Theorem 7**: All well-typed, pure, non-recursive terms are strongly normalizing. - -**Proof**: By logical relations. Define a family of predicates Rτ such that: -- Rᵢₙₜ(e) iff e ⟶* n for some n -- Rₛₜᵣᵢₙ(e) iff e ⟶* s for some s -- Rτ₁→τ₂(e) iff for all v ∈ Rτ₁, e v ∈ Rτ₂ - -Show by induction that Γ ⊢ e : τ implies e ∈ Rτ.

For overlapping redexes (critical pairs), we show -they can be joined. □ - -## Subject Expansion - -**Theorem 10 (Subject Expansion for Values)**: If e ⟶ v and Γ ⊢ v : τ, -then Γ ⊢ e : τ. - -**Proof**: By case analysis on the reduction rule. Each rule's conclusion -type equals or is a supertype of the input type. □ - -Note: Subject expansion does not hold in general due to effects—a stuck -effectful term may not have the same type as a value. - -## Parametricity - -**Theorem 11 (Parametricity)**: Polymorphic functions satisfy the abstraction theorem. - -For f : ∀α. τ[α] and any types A, B with relation R ⊆ A × B: -If (a, b) ∈ R, then (f[A](a), f[B](b)) ∈ τ[R] - -This enables "free theorems" derivation. - -**Example**: For f : ∀α.

ML features four -dialects—Me, Solo, Duet, and Ensemble—that progressively reveal language -complexity while maintaining semantic consistency. Key contributions include: -a unified type system spanning visual blocks to textual code, an effect system -that treats AI as a first-class computational effect, and the Newtonian spectrum -of seven specialized AI agents for orchestration. - -## 1. Introduction - -### 1.1 Motivation - -Contemporary programming languages face a tension between accessibility and -expressiveness. Educational languages (Scratch, Logo) sacrifice power for -simplicity. Professional languages (Rust, Haskell) sacrifice accessibility -for expressiveness. We propose a third way: progressive disclosure within -a single coherent language. - -Additionally, existing languages treat AI as an external service rather than -an integrated capability. We argue that modern languages should embrace AI -as a first-class citizen, with proper typing, effect tracking, and composition. - -### 1.2 Contributions - -1. **Progressive disclosure** via four dialects with consistent semantics -2. **Visual affine types** introducing resource management to young learners -3. **AI effect system** treating AI operations as tracked effects -4. **Session types** for human-AI collaboration protocols -5. **Agent calculus** for multi-agent AI orchestration -6. **Newtonian spectrum** partitioning AI concerns into seven agents - -### 1.3 Paper Organization - -Section 2 presents the four dialects. Section 3 covers the type system. -Section 4 describes the effect system. Section 5 details AI integration. -Section 6 discusses implementation.
