It +is written in EBNF; `{ x }` means repetition, `[ x ]` means optional. + +[source,ebnf] +---- +expr ::= literal + | var + | expr binop expr + | unop expr + | "if" expr "do" expr "else" expr "end" + | "case" expr "do" clause { clause } "end" + | "{" [ expr { "," expr } ] "}" + | "[" [ expr { "," expr } ] "]" + | "%{" [ map_pair { "," map_pair } ] "}" + | "%" alias "{" [ field_pair { "," field_pair } ] "}" + | callee "(" [ expr { "," expr } ] ")" + | var "=" expr + +clause ::= pattern [ "when" guard ] "->" expr +pattern ::= "_" | var | literal + | "{" [ pattern { "," pattern } ] "}" + | "[" [ pattern { "," pattern } ] "]" + | "%{" [ map_pattern { "," map_pattern } ] "}" + | "%" alias "{" [ field_pattern { "," field_pattern } ] "}" + | pattern "=" pattern + | "^" var + +guard ::= gexpr + | guard "and" guard + | guard "or" guard + | "not" guard + +gexpr ::= "is_integer" "(" var ")" | "is_binary" "(" var ")" + | "is_atom" "(" var ")" | "is_list" "(" var ")" + | "is_map" "(" var ")" | "is_boolean" "(" var ")" + | "byte_size" "(" var ")" | "length" "(" var ")" + | var cmp var | var cmp literal + | var "in" "[" literal { "," literal } "]" + | var arith var + +binop ::= "+" | "-" | "*" | "div" | "rem" + | "==" | "!=" | "<" | "<=" | ">" | ">=" + | "and" | "or" | "<>" +unop ::= "-" | "not" +callee ::= var | alias "." var +alias ::= "Elixir."? UpperIdent {"." UpperIdent} +---- + +The elaborator works on the *expanded* AST, so `if`, `unless`, `with`, `for`, +and the pipe operator are already reduced to `case`/function calls (or rejected, +for `for`). The grammar above is the post-expansion surface, not the source +surface; the Face attributes are attached to source definitions before expansion. + +== Base types and refinements + +[cols="2,3",options="header"] +|=== +| Type | Representation / invariant +| `integer` | Mathematical integer. Elixir bignums are exact; no overflow. +| `nat` | `{n : integer \| 0 <= n}` +| `boolean` | `true` or `false` +| `atom` | A finite atom type, inferred from literals and specs +| `binary` | Byte string with `byte_size` and `binary_part` +| `bitstring` | Bit string; byte-aligned in the MVP +| `list(a)` | Finite cons list +| `map(k, v)` | Finite functional map +| `tuple(a, b, ...)` | Fixed arity, positional +| `struct(M)` | A map with `__struct__ = M` and declared fields +| `option(a)` | `:none` or `{:some, a}` +| `result(a, e)` | `{:ok, a}` or `{:error, e}` +|=== + +Refinements are predicates over a distinguished value variable: + +[source,text] +---- +{ v : integer | 0 <= v and v <= 1048576 } +{ s : binary | byte_size(s) <= 1048576 } +{ xs : list(integer) | length(xs) <= 1024 } +---- + +The elaborator keeps refinements in a normal form: conjunctions of linear +arithmetic atoms, equalities over uninterpreted functions, finite-map operations, +and length/byte-size atoms. Anything outside the fragment is rejected rather than +sent to SMT as an opaque predicate. This is what makes the Dedukti +reconstruction tractable. + +== Typing rules + +The judgment is + +[source,text] +---- +Gamma ; Sigma |- e : { v : T | phi } @ ell +---- + +where `Gamma` maps variables to refined types, `Sigma` is the capability +footprint, `ell` is the confidentiality label, and `phi` may mention `v` and the +variables in `Gamma`. + +Selected rules: + +[source,text] +---- +(x : {v:T | phi}) in Gamma +-------------------------------- T-Var +Gamma ; Sigma |- x : {v:T | phi[x/v]} @ ell(x) + +---------------------------- T-Int +Gamma ; Sigma |- n : {v:integer | v = n} @ public + +Gamma ; Sigma |- e1 : {v:T1 | phi1} @ l1 +Gamma ; Sigma |- e2 : {v:T2 | phi2} @ l2 +l = l1 join l2 +-------------------------------- T-Pair +Gamma ; Sigma |- {e1, e2} : {v:T1*T2 | phi1[fst v/v] and phi2[snd v/v]} @ l + +Gamma ; Sigma |- e : {v:T | phi} @ l +for each i: Gamma, pat_i : T, guard_i |- branch_i : {v:U | psi_i} @ l +exhaustive(pat_1 ... pat_n) +-------------------------------- T-Case +Gamma ; Sigma |- case e of pat_i when guard_i -> branch_i end + : {v:U | psi} @ l + where psi = forall i.

Each branch receives +the scrutinee's refinement plus the branch guard; the result's refinement is the +conjunction of the branch refinements under their guards. If a branch is +unreachable, its implication is vacuous; that is checked, not assumed. If the +match is non-exhaustive, the rule does not apply (`Q-202`). + +Function application: + +[source,text] +---- +f : (x_1 : T_1) -> ... -> (x_n : T_n) -> {v:U | psi} in Gamma +Gamma ; Sigma |- a_i : {v:T_i | phi_i} @ l_i +-------------------------------- T-App +Gamma ; Sigma |- f(a_1, ..., a_n) + : {v:U | psi[a_i/x_i]} @ join(l_1, ..., l_n) + with side condition: pre_f[a_i/x_i] is entailed by phi_1 ... phi_n +---- + +The side condition is the proof obligation that the caller meets the callee's +precondition. It is generated as a VC; it is not a runtime check. + +== Guards and pattern refinement + +A guard is a conjunction of decidable atoms. The elaborator translates each atom +into a refinement: + +[cols="2,3",options="header"] +|=== +| Guard | Refinement +| `is_integer(x)` | `x : integer` +| `is_binary(x)` | `x : binary` +| `byte_size(x) <= n` | `byte_size(x) <= n` +| `x > n` | `x > n` +| `x in [a, b, c]` | `x = a or x = b or x = c` +| `is_atom(x)` | `x : atom` +| `length(xs) <= n` | `length(xs) <= n` +|=== + +Guards that cannot be expressed in the refinement fragment are rejected +(`Q-201`), not treated as opaque booleans. This prevents the classic +"guard says `valid?(x)` but the solver knows nothing" hole. + +Pattern matching refines map and struct fields structurally. For a map pattern +`%{id: id, digest: d}`, the branch receives `id in keys(m)`, `d = m[id]`, and the +map's remaining keys are unconstrained. For a struct pattern, the field types and +invariants are projected from the struct declaration. A missing field is a type +error, not a runtime `KeyError`. + +== Totality and measures + +A recursive definition is accepted only with a measure in one of these forms: + +[source,text] +---- +measure ::= size(x) -- list/map/binary/tuple size + | n - k -- affine variant of a nat parameter + | lex(m1, m2, ...) -- lexicographic product + | f(args) -- user function, must be nat-valued and total +---- + +For each recursive call, the elaborator emits: + +[source,text] +---- +0 <= measure(args') and measure(args') < measure(current args) +---- + +Why3 discharges these with the same SMT portfolio. If a decrease obligation is +`unknown`, the function is rejected; there is no "trust the termination checker" +mode. For `Enum.reduce`, the measure is the length of the input list and the +reducer must be total; a reducer that calls back into a non-total function is +`Q-206`. + +Mutual recursion is accepted only with a lexicographic measure over the tuple of +arguments, and only when the call graph is a finite DAG of strongly connected +components. The MVP does not support mutual recursion; it is Phase 4. + +== Why3 projection + +The projection is a total function `to_why : Term -> WhyML`.

The Elixir `old` in `@post` maps to `old` in WhyML. + +== VC generation and the Dedukti witness + +Why3 splits each function's verification condition at match branches, assertions, +and `let` boundaries. The output is a set of named goals: + +[source,text] +---- +Verisim_Spec.checked_digest'vc +Verisim_Spec.checked_digest'vc.0 -- empty branch +Verisim_Spec.checked_digest'vc.1 -- non-empty branch +---- + +Each goal is sent to the SMT portfolio (`z3`, `cvc5`, `alt-ergo`) with a +timeout. An `unsat` answer is necessary but not sufficient for a Receipt. The +`why3-dk` pass reconstructs a Dedukti proof for goals in the *reconstructible +fragment*: + +* quantifier-free linear integer arithmetic; +* equality and congruence; +* uninterpreted functions; +* algebraic data types with constructor disjointness and injectivity; +* finite maps with `get`/`set` axioms; +* byte strings with length and substring axioms. + +The reconstruction is not a transcript of the SMT solver's internal proof. It is +a proof term built from the goal's clausification and the fragment's rules. That +makes it independent of the solver, and it makes the translator a TCB component: +the `.dk` term must be checked by `dkcheck`, and the translator must be reviewed +(and, in Phase 5, proved). + +A schematic `.dk` file: + +[source,text] +---- +# why3-dk output, fragment: QF-LIA + UF + bytes +bytes : Type. +length : bytes -> int. +digest_of : bytes -> bytes. +checked_digest : bytes -> result. + +ax_length_nonneg : Pi (b : bytes). 0 <= length b. + +thm_checked_digest_post : + Pi (payload : bytes). + length payload <= 1048576 -> + Pi (r : result). + r = checked_digest payload -> + (Sigma (d : bytes). r = Ok d /\ d = digest_of payload) \/ + (Sigma (e : string). r = Error e). +---- + +The real output is a full λΠ term, not a statement. The point of the sketch is +the shape: the theorem is about the same `checked_digest` and `digest_of` that +Why3 used. If the translator cannot produce a term, the goal is `UNCHECKED` and +cannot enter a Receipt. + +== Information flow: `@secret`, `@declassify`, and MPR R5 + +The label lattice for the MVP is two-point: + +[source,text] +---- +public <= internal <= confidential <= secret +---- + +The typing judgment carries a label; the rules are standard TINI: + +[source,text] +---- +Gamma |- e : T @ l +l <= l' +---------------- T-SubLabel +Gamma |- e : T @ l' + +Gamma, x : T @ l |- e : U @ l' +l' <= l +---------------- T-Fun +Gamma |- (x) -> e : (x : T @ l) -> U @ l' + +Gamma |- e : T @ secret +Gamma |- declassify(e, reason) : T @ public + with obligation: reason is a declared declassification policy +---------------- T-Declass +---- + +Implicit flows are controlled by the PC label: a branch on a secret raises the +label of everything computed inside it. A secret-dependent `if` that returns a +public value is rejected unless the whole expression is declassified. + +The MPR R5 composition rule is a separate check over the process footprint. A +process's footprint is a set of `(capability, resource, label)` triples. The +corridor relation is + +[source,text] +---- +read in Sigma, write in Sigma, label(read) !<= label(write) +------------------------------------------------------------ R5-VIOLATION +Sigma is an exfiltration corridor +---- + +For example, a process that reads a `:confidential` entity field and writes to a +`:public` network socket is a corridor. The checker rejects it unless there is a +`@declassify` on the value and a policy that permits the release. The rule is +*compositional*: checking each function in isolation would miss the pair, so the +elaborator computes the footprint product for every process and for every +module that can be composed into a process. + +The canonical `fs.read || net.send` example is rejected for two reasons: the +ambient `File` and `:gen_tcp` capabilities are absent from the default `Sigma`, +and the label flow is a corridor. A future verified `read_file`/`send_socket` +pair would still need the label proof. + +The MPR adapter maps `@cap` atoms to MPR capability names: + +[cols="2,2",options="header"] +|=== +| Face | MPR `Sigma` +| `read: [:entity]` | `read(entity)` +| `write: [:entity]` | `write(entity)` +| `call: [{Verisim.Nif, [hash: 2]}]` | `call(Verisim.Nif, hash, 2)` +| `clock` | `clock` +| `rand` | `rand` +| `log` | `log` +| `fs`, `system`, `port`, `eval` | absent by default; require an explicit grant +|=== + +If the pinned MPR revision uses different names, only the adapter changes. The +R5 rule and the obligation are quintessence's; the capability algebra is MPR's. + +== The macro-expansion firewall + +The firewall has three gates.

A macro that reads a *stable* environment +variable is still rejected unless the variable is on the allowlist, because the +expansion is part of the proof identity. + +If `bubblewrap`/`nsjail` is unavailable, G0b fails closed (`Q-111`). There is no +"run unsandboxed" mode in `--strict`; a developer may pass +`--allow-unsafe-expansion` locally, but the resulting `.qir` is stamped +`expansion: unsafe` and cannot enter a Receipt. + +=== G0c: bytecode import audit + +After compilation, the `.beam` file is read with `:beam_lib.chunks/2`: + +[source,elixir] +---- +{:ok, {_, [imports: imports, atoms: atoms]}} = + :beam_lib.chunks(beam_path, [:imports, :atoms]) + +# imports :: [{module, [{fun, arity}]}] +Enum.each(imports, fn {mod, funs} -> + Enum.each(funs, fn {fun, arity} -> + unless Quintessence.Imports.allowed?(mod, fun, arity) do + raise Quintessence.Error, code: "Q-112", message: "#{mod}.#{fun}/#{arity}" + end + end) +end) + +# Banned atoms catch dynamically constructed calls that the AST scan missed. +unless Enum.all?(atoms, &Quintessence.Atoms.allowed?/1) do + raise Quintessence.Error, code: "Q-113" +end +---- + +The import table catches static remote calls. It does not catch `apply/3` with a +computed module; G0a rejects the literal `apply` and `Module.concat`, and the +atom audit catches the constructed atom. The combination is not a proof of +non-interference, but it closes the obvious holes. + +=== What the firewall does not do + +* It does not sandbox *runtime*. A verified module can still call a banned + function through a `@trusted` boundary; the boundary is named in the receipt. +* It does not prove that an allowed macro is semantically correct. The allowlist + is a reviewed TCB. +* It does not prevent a macro from emitting a *valid but wrong* AST. That is + caught by the subset checker and the VCs, not by the firewall. +* It does not protect against a compromised Elixir compiler. The compiler is in + the trust ledger. + +== Validation strategy + +Layer A is validated at four levels: + +. *Golden corpus.* A set of small modules with hand-written `.qir` and expected + VCs. Any change to the elaborator that changes a hash or a VC is reviewed. +. *Differential testing.* For every function in the corpus, generate random + inputs and compare the Elixir result with the Why3 model's result (via Why3's + extraction or a reference interpreter). A mismatch is a bug in the model or + the code. +. *Mutation testing.* ECHIDNA mutates the specification and the implementation; + a surviving mutant is a missing postcondition or a weak VC. +. *Proof replay.* `why3 replay` re-runs the saved proof sessions; a proof that no + longer checks is a regression. + +The corpus is deliberately adversarial: empty lists, zero-length binaries, +maximum sizes, maps with missing keys, and branches that are unreachable under +the precondition. A specification that only passes on the happy path is a +vacuous specification with good marketing. + +== Open issues + +* *Floats.* The MVP rejects them. `drift` is modeled in basis points, not as a + float, because SMT floating-point reasoning is a different theory and the + BEAM's float semantics are not the IEEE754 model we would want to prove + against. +* *Bignums.* Elixir integers are arbitrary precision; Why3 `int` is mathematical. + This is a good match for pure code, but a NIF that takes a `u64` needs a range + refinement at the boundary. Layer C carries that obligation. +* *Bitstrings.* Byte-aligned binaries are modeled; arbitrary bit-level matching + is Phase 4. +* *Closures.* First-class functions are rejected in the MVP. `Enum.map` with a + literal lambda is inlined; a closure that escapes is `Q-201`. +* *`Enum.reduce` measures.* Inferring a decreasing measure for an arbitrary + reducer is hard. The MVP requires an explicit `@measure`; Phase 3 adds + inference for the common `acc`-size patterns. +* *Map ordering.* Why3 maps are functional; Elixir maps have no observable order + in the subset. The canonical form sorts keys for hashing, not for semantics. +* *Struct updates.* `%{s | f: v}` is pure and modeled; a struct with a field + that is a function or a PID is rejected. +* *Exceptions.* `raise` is rejected in the pure subset. A function that can fail + returns `result`; this is a source-level discipline, not an automatic + translation. diff --git a/docs/architecture/QUINTESSENCE-LAYER-B.adoc b/docs/architecture/QUINTESSENCE-LAYER-B.adoc new file mode 100644 index 0000000..a342f29 --- /dev/null +++ b/docs/architecture/QUINTESSENCE-LAYER-B.adoc @@ -0,0 +1,651 @@ +// SPDX-License-Identifier: CC-BY-SA-4.0 +// Copyright (c) 2026 Jonathan D.A.

It assumes link:QUINTESSENCE.adoc[the main specification] and +the pinned `choreographic-types` fragment recorded there. + +[IMPORTANT] +==== +Reference design. The K-CUT theorems cited here are machine-checked in +`choreographic-types` at the pinned revision, *for the fragment stated in that +repository*. This document may not extend that fragment by assertion. Where a +claim is outside it, the text says `OPEN` or `ASSUMED`. +==== + +== Scope and the proved fragment + +`choreographic-types` proves K-CUT for: + +* finite graded global types; +* messages and *binary* choice; +* endpoint projection with *plain merge* (a non-participant's two branches project + identically); +* cuts as frontiers, with `Consistent` and `Projectable` side conditions; +* a parametric resource algebra, with `Loss`, `MaxPlus`, and `HWM` instances; +* an asynchronous layer where messages and selections may be in flight, with + causal cuts. + +It does **not** cover: recursion (mu-types), full merge, delegation, n-ary choice +(a fold of binary is future work), queues-as-data, data-dependent warrants, or the +general reply chain beyond the two-message protocol. Quintessence's MVP stays +inside the fragment. A protocol outside it is `Q-402`, not silently approximated. + +The practical consequence for OTP: the MVP supports *linear request/reply +protocols with a bounded number of roles*, optionally with binary choice, and +without recursive protocols. That is enough for a commit/attest entity; it is not +enough for a general session-typed server. Phase 4 extends the fragment in +co-development with `choreographic-types`, not in quintessence alone. + +== Protocol syntax + +=== Global and local types + +[source,ebnf] +---- +G ::= "end" + | p "->" q ":" l "{" G "}" -- message + | G "." G -- sequence + | G "+" G -- binary choice + | "mu" X "." G | X -- recursion (OPEN, rejected in MVP) + +L ::= "end" + | "!" l "." L -- send + | "?" l "." L -- receive + | L "+" L -- choice + | "mu" X "." L | X -- recursion (OPEN) +---- + +A global type is a partial causal order. Projection `G ↾ p` gives the local type +for role `p`. A *cut* is a downward-closed set of events; it is *consistent* for +`p` when every event before the frontier that `p` can observe is included, and +*projectable* when the truncated global type still projects. Both side conditions +are load-bearing in the keystone: without `Projectable` the equality fails (1 vs +2), and without `Consistent` it fails (1 vs 2) in the `choreographic-types` +rejection tests. + +=== The Face form + +The Face's `@choreography` is a literal keyword list. It elaborates to a linear +global type; binary choice is a future `choices:` key. Example: + +[source,elixir] +---- +@choreography [ + roles: [:client, :entity, :auditor], + messages: [ + {:client, :entity, :commit, [:payload]}, + {:entity, :client, :committed, [:version, :digest]}, + {:entity, :auditor, :attest, [:version, :digest]} + ], + knowledge: [ + {:client, :entity, :committed, [:version, :digest], {:call, :commit}}, + {:auditor, :entity, :attest, [:version, :digest], {:cast, :attest}} + ], + forbid: [ + {:entity, :knows, {:auditor, :received, :attest}, :cast} + ] +] +---- + +The global type is: + +[source,text] +---- +client -> entity : commit(payload) . +entity -> client : committed(version, digest) . +entity -> auditor : attest(version, digest) +---- + +The `client -> entity` message is a `call`; `entity -> client` is its reply. The +`entity -> auditor` message is a `cast`. The protocol is linear, three roles, no +choice, no recursion: inside the MVP fragment. + +== From GenServer callbacks to local types + +The mapping is static where possible and monitored where static checking is not +sound. + +[cols="2,2,3",options="header"] +|=== +| Callback | Local type | Static check + +| `handle_call({:commit, p}, from, s)` | `?commit . !committed . end` at `entity` +| The clause pattern must match the declared message shape; the reply must be + `{:reply, {:ok, v, d}, s'}` or an error shape declared in the Face. + +| `handle_cast({:attest, v, d}, s)` | `?attest . end` at `auditor` +| The clause must not reply; the `@post` must not mention a remote claim. + +| `handle_info(msg, s)` | any +| A catch-all clause is required and must be proved to preserve `@invariant`; + an unhandled message is `Q-403`. + +| `init/1` | `end` +| Establishes `@invariant`; no message may be sent before the state is valid. + +| `terminate/2` | `end` +| Must not send a message that a knowledge claim depends on; termination is not + a commit. +|=== + +The static check is not enough on its own: a `handle_info` can receive a message +that is not in the protocol, and a `GenServer.call` can time out. Two mechanisms +close the gap: + +. *Callback coverage.* The protocol's labels are matched against the callback + clauses. Every declared message has exactly one handler; every handler's label + is declared. A missing handler is `Q-403`; an extra handler is allowed only if + it is a catch-all that logs/rejects and preserves the invariant. +. *Runtime conformance monitor.* In test and staging, a `:sys`/`:erlang.trace` + based monitor records `send`, `receive`, `call`, and `cast` events and checks + them against the projected local type. A deviation is a test failure. This is + validation, not verification; it catches a Face that lies about the code. + +The monitor is important because the Face is an annotation. A developer can +declare a `call` while the code uses `cast`; the static checker sees the +annotation, not the call. The bytecode import audit and the runtime monitor are +the two independent checks that the annotation matches the code. The import +audit can see `GenServer.call/3` and `GenServer.cast/2`; the monitor sees the +actual events. + +== Cuts, views, and knowledge + +=== Events and causality + +An event is one of: + +[source,text] +---- +send(i, j, l, v) -- i sends message l with payload v to j +recv(i, j, l, v) -- i receives it +commit(i, s) -- i's local state becomes s +crash(i) -- i stops +restart(i, e) -- i starts a new incarnation with epoch e +---- + +The causal order `->` is the transitive closure of: + +* program order at each process; +* `send(i,j,l,v) -> recv(i,j,l,v)` for the same message instance; +* `commit(i,s) -> send(i,j,l,v)` if the send is causally after the commit. + +A *cut* `k` is a downward-closed set of events. A cut is *consistent for i* when +it does not include a receive whose send is outside the cut. The *view* of `i` at +`k` is the sequence of `i`'s events in `k` plus the messages delivered to `i` in +`k`: + +[source,text] +---- +view_i(k) = ++ +---- + +Two worlds `w` and `w'` are *i-indistinguishable*, written `w ~_i w'`, when +`view_i(w) = view_i(w')`. Knowledge is truth at every indistinguishable world: + +[source,text] +---- +K_i(phi) at w iff forall w'. w ~_i w' => phi(w') +---- + +Knowledge is factive because `~_i` is reflexive. Belief would drop reflexivity; +quintessence does not model belief in the MVP. + +=== K-CUT-LOSS + +Let `gamma` be an element of a resource algebra. `choreographic-types` proves, +for every party `p` and consistent cut `c`: + +[source,text] +---- +grade (G restricted to c) restricted to p + = lgrade (proj p G restricted to cutproj p c) +---- + +This is an equality, parametric in the algebra, using only `1 (x) x = x` and +`x (+) x = x`. It holds synchronously and asynchronously (the receiver still +waiting contributes the unit). The instances are `Loss`, `MaxPlus`, and `HWM`. + +Quintessence uses it three ways: + +. *Loss*: a party's view loses exactly the information the grade says it loses. + This justifies the knowledge bound: if the global loss grade is `l`, the + party's local grade is `l` restricted to its view. +. *HWM*: the global occupancy grade restricted to a party is the party's local + mailbox high-water mark. This is the bridge from protocol occupancy to a + per-process mailbox bound. It is not a cost bound. +. *MaxPlus*: the global cost grade restricted to a party is the party's local + cost. This is used for protocol-level timing, not for NIF WCET; see the + warning below. + +[WARNING] +==== +`choreographic-types`' `MaxPlus` is an Agda instance. `tropical-types`' `MaxPlus` +is a Lean formalization. They have the same laws and the same name, but the +Lean-to-Agda bridge is explicitly open in `choreographic-types`' proof status. +Quintessence MUST report them as two separate discharges. A Layer C NIF bound +does not justify a Layer B grade without the bridge. +==== + +=== K-CUT-WARRANT + +The warrant component is a *bound*, not an equality. In the Kripke frame whose +worlds are `p`-consistent cuts and whose accessibility is sameness of `p`'s view, +`choreographic-types` proves: + +* `p` knows its own restricted grade at every world (`knows-own-grade`); +* if every grade in `G` is above the unit, `grade restricted to p <= grade G`; +* if every grade is below the unit, `grade G <= grade restricted to p`; +* knowledge is monotone along the party-access preorder (`knows-mono`); +* the local frontier is known (`knows-local-cut`). + +The direction of the bound depends on where the unit sits in the algebra's order. +For `HWM` and `MaxPlus`, `p`'s view is a lower bound on the global grade; for +`Loss`, it is an upper bound in the loss order. Any quintessence claim must say +which direction it is using. A claim of the form "the global grade is exactly +`p`'s grade" is false in general; it is the `GlobalGradeKnown` rejection test in +`choreographic-types`. + +== The reply rule and the falsifier + +The pre-registered falsifier is the centre of Layer B. After an asynchronous +send, the sender's view is consistent with two worlds: one where the message was +delivered and one where it is still in flight (or lost). Therefore: + +[source,text] +---- +send(i, j, m) => not K_i(received_j(m)) +---- + +`AsyncKnowledge.sender-cannot-know-receipt` proves this for the asynchronous +frame; the synchronous frame has the dual `sync-sender-knows-receipt`. The +receiver, by contrast, knows it was sent once it receives: +`AsyncKnowledge.receiver-knows-sent`. + +A reply restores the sender's knowledge, but only for the two-message protocol +`0 -> 1 : a . 1 -> 0 : b`: + +[source,text] +---- +j committed s at v +j sent reply(s, v, h) after the commit +i received reply(s, v, h) +h = H(s, v) +epoch(reply) = epoch(j) +-------------------------------------------------- K-REPLY +K_i(committed_j(s, v)) +---- + +The side conditions are load-bearing: + +* *After the commit*: a reply sent before the state transition is not a warrant. +* *Authenticated*: an unauthenticated message can be forged; the frame assumes + an authenticated channel. +* *Epoch match*: a reply from a previous incarnation is not a warrant for the + current one. +* *No rollback*: the version is monotonic; a later reply with a lower version is + stale and rejected. + +The general reply chain (i sends to j, j sends to k, k replies to j, j replies to +i) is **OPEN** in `choreographic-types`. Quintessence may not claim it. A +three-message protocol is either decomposed into the two-message fragment (if the +knowledge claim is local to a pair) or marked `assumed` with a visible receipt. + +=== Typing rules + +[source,text] +---- +Gamma |- e : unit +-------------------------------- K-SEND +Gamma |- send(i,j,l,v) : K_i(sent(i,j,l,v)) ; not K_i(received_j(l,v)) + +Gamma |- e : unit +-------------------------------- K-CAST +Gamma |- cast(i,j,l,v) : K_i(sent(i,j,l,v)) ; not K_i(received_j(l,v)) + +Gamma |- e : T +-------------------------------- K-RECV +Gamma |- recv(i,j,l,x) : K_i(received(i,j,l,x)) ; x : T + +Gamma |- call(i,j,l,v) : reply r +-------------------------------- K-CALL +Gamma |- call(i,j,l,v) : K_i(received(r)) ; + (warrant(r) => K_i(committed_j(s, v))) + +Gamma |- monitor(i,j) : unit +-------------------------------- K-MON +Gamma |- monitor(i,j) : K_i(terminated(j, reason)) ; not K_i(state_j(s)) + +Gamma |- restart(j, e+1) : unit +-------------------------------- K-RESTART +Gamma |- restart(j, e+1) : K_i(terminated(j, _)) ; + (durable_receipt(s, e) => K_i(state_j(s))) +---- + +`K-CALL` is the only rule that can introduce a remote commitment, and only when +the reply carries a warrant. `K-SEND` and `K-CAST` are deliberately identical in +their knowledge effect: send is not receipt, and cast is not a commit. + +== Enforcing the falsifier + +The Face's `@choreography` elaborator builds a derivation for each `knowledge` +entry. The algorithm is a bounded proof search over the rules above: + +[source,text] +---- +for each claim (knower, agent, fact, vars, channel): + if channel = {:call, label}: + require a reply message from agent to knower with the same label + require the reply payload vars to include the fact's vars + require the call to precede the reply in the global type + emit K-REPLY obligation + if channel = {:cast, label} or {:send, label}: + require knower = receiver(agent -> knower : label) + emit K-RECV obligation (receiver knows sent) + do NOT emit K-REPLY + if knower = sender and fact concerns the receiver's state: + reject Q-401 + if the protocol is outside the fragment: + reject Q-402 +---- + +The search is sound but incomplete: it may reject a valid claim it cannot derive +(a false positive), but it never accepts a claim that the fragment does not +warrant. That is the right direction for a verifier. A developer who believes a +rejected claim is valid must either extend the protocol to a proved fragment +(usually: add a reply) or mark the claim `assumed` with a receipt. + +`forbid` clauses are negative obligations. The checker attempts to derive the +forbidden claim; if it succeeds, the module is rejected and the derivation is +printed with the falsifier name. In the worked example, the forbidden claim +`entity knows auditor received attest` is not derivable, so the module passes; +if a future edit adds a knowledge entry with `{:cast, :attest}` from the entity's +perspective, the derivation succeeds and the module fails. + +== Occupancy: the HWM calculus + +A mailbox is a queue with a high-water mark. The HWM grade is an occupancy grade, +not a cost grade. The model has three layers: + +. *Protocol occupancy.* The global protocol's HWM grade at a cut; K-CUT-LOSS + projects it to each role. This gives a per-role bound in terms of the + protocol, independent of the implementation. +. *Queue discipline.* The mailbox is a FIFO with selective receive. The checker + computes the arrival curve and the service curve for each pattern class. +. *Operational reading.* `occupancy-types`' Session IR provides the linear + buffer/endpoint model and the HWM reading. Its HWM grade algebra is planned + (R2-R3); the Agda HWM instance in `choreographic-types` is the algebra used for + K-CUT. + +=== Arrival and service bounds + +For a mailbox with burst `b`, arrival rate `lambda`, and worst-case handler +service `W`, the backlog bound is: + +[source,text] +---- +if lambda < 1 / W: + HWM <= b + lambda * W / (1 - lambda * W) +else: + HWM is unbounded; reject (Q-404) +---- + +The simpler bound `HWM <= b + lambda * W` is used in the MVP; it is conservative +and easy to check in linear arithmetic. `W` comes from Layer C's `MaxPlus` bound +for the handler's NIFs plus the pure handler cost; `lambda` and `b` come from the +Face's `@arrival` annotation or from a measured trace. A measured trace is not a +proof for all executions; the receipt records `arrival: measured` and the bound is +labelled `BOUNDED`. + +=== Selective receive + +`receive` scans the mailbox from the front and removes the first message that +matches any clause. Messages that do not match stay. The cost is O(n) per scan, +and a class that is never matched can starve. The checker models each pattern +class as a separate queue: + +[source,text] +---- +class P1: arrival lambda1, service mu1 +class P2: arrival lambda2, service mu2 +... +starvation(Pi) iff lambda_i >= mu_i +---- + +A `receive` with an `after` timeout is not a fix: the timeout branch is a +protocol event, and the spec must say what happens to the unmatched message. A +catch-all clause that drops messages is allowed only if the protocol's loss grade +says the drop is permitted; otherwise it is `Q-404`. + +=== Backpressure + +If the bound cannot be proved, the module MUST declare backpressure: + +* a bounded internal queue with `handle_continue` and a `{:noreply, ...}` that + refuses new work when full; +* a synchronous `GenServer.call` handshake that blocks the producer; +* a supervisor-level rate limit with a proved arrival curve. + +`GenServer.cast` alone is unbounded by construction. `:max_heap_size` bounds the +process heap, not the mailbox. A `:busy_port` or `:fullsweep_after` setting is not +a backpressure proof. + +== Crashes, links, and supervision + +A crash truncates the cut. The state is gone; in-flight messages to the crashed +process are lost; messages it sent remain. A restart creates a new incarnation +with a new epoch. + +[cols="2,3,3",options="header"] +|=== +| Event | Knowledge | Invariant obligation + +| `monitor` / `:DOWN` | `K_i(terminated(j, reason))`; not `K_i(state_j(s))` +| The monitor's post-state must not depend on the target's state. + +| `link` / exit signal | If trapping, `K_i(exit(j, reason))`; if not, `i` may die +| The supervisor's strategy must be modeled; an unhandled exit is a crash. + +| `one_for_one` restart | New epoch; old knowledge is stale +| `init/1` re-establishes `@invariant`; a claim about the old state requires a + durable receipt. + +| `rest_for_one` / `one_for_all` | Global cut; all children restart +| The invariant must be inductive over the restart, not just over normal + transitions. + +| `max_restarts` escalation | Subtree termination +| The spec must state whether termination is permitted; it is not silently + ignored. +|=== + +`ProofTransport` is the certificate that carries a proof across a restart. It +has two parts: a *durable state receipt* (the new incarnation's state hash and +epoch) and a *re-establishment proof* (the invariant holds for `init/1` and the +new state). Without both, a claim that mentions the old process's state is +`Q-401` after a restart. + +== Apalache encoding + +The TLA+ model is an abstraction of the protocol, not of the Elixir code.

Increasing the bounds increases the state space; the MVP's CI +runs the small instance on every PR and a larger one nightly. + +=== What Apalache proves, and what it does not + +* It proves that no execution of the *model* up to length 12 reaches a state + violating the invariants. That is `BOUNDED`. +* It does not prove the model refines the Elixir code. The refinement is the + Face's static mapping plus the runtime monitor; the formal refinement + obligation is Phase 5. +* It does not prove the model refines the Agda K-CUT semantics. The encoding is + validated by trace tests and reviewed; a mechanized refinement is a research + item. +* It does not prove liveness. The MVP uses safety invariants; fairness is an + assumption for eventual delivery, not a checked property. + +The honest label in the receipt is `apalache: bounded(12, MaxMailbox=2, +MaxEpochs=1)`, not "protocol proved". + +== Composition theorem + +[source,text] +---- +Theorem (Layer composition, target statement). +Assume: + (A) every Layer A handler satisfies its pre/post/invariant contract; + (B) the protocol is well-typed in the proved K-CUT fragment, every knowledge + claim has a K-REPLY/K-RECV warrant, and every forbidden claim is underivable; + (C) the mailbox HWM bound is proved from the protocol grade and the service + bound, or backpressure is present; + (D) every NIF receipt is valid and its MaxPlus bound is within budget; + (E) channels are authenticated, the system is crash-stop (no Byzantine faults), + and the scheduler is fair. +Then: + (1) no reachable state violates the module invariant; + (2) no actor makes an unwarranted remote claim. +---- + +Proof sketch. Induct over cuts. At the empty cut, `init/1` establishes the +invariant (A). For a normal transition, Layer A gives the local state change and +preserves the invariant; K-CUT gives projection and the knowledge bound; the +occupancy bound gives the mailbox invariant; Layer C gives the native refinement +for any NIF call. For a crash, the cut is truncated; the invariant is +re-established by `init/1` on restart, or the subtree terminates and the +invariant is vacuous for that subtree. For a knowledge claim, the only +introduction rule for a remote commitment is K-REPLY; K-SEND and K-CAST cannot +introduce it, so the falsifier is respected. The composition of the layer +theorems is the induction step. + +The proof is **not** machine-checked as a whole in the MVP. The K-CUT metatheory +is; the Layer A VCs are; the Layer C receipts are. The composition is a paper +argument with a named obligation. Phase 5 formalizes it in Agda, with the +composition as a theorem over the layer interfaces. + +== Validation strategy + +. *Trace conformance.* Run the app under the runtime monitor; every event must + match the projected local type. A deviation is a test failure. +. *Apalache counterexamples.* A counterexample is replayed in the Elixir app; if + it cannot be reproduced, the abstraction is wrong and must be fixed before the + model is trusted. +. *Concuerror cross-check.* The same protocol is run under Concuerror with a + small message bound; its schedules should be a subset of the TLA+ model's + traces. A schedule the model does not allow is a modeling bug. +. *Mutation.* ECHIDNA mutates `call` to `cast`, drops replies, reorders messages, + and restarts processes. A surviving protocol mutant is a missing K-CUT + obligation or an unreachable `forbid`. +. *Mailbox measurement.* The HWM bound is compared with a production measurement + over a representative workload. A measurement above the bound is a + stop-and-ledger event: either the arrival curve is wrong or the bound is not a + bound. + +== Open issues + +* *General reply chain.* The two-message theorem is the only receipt-grade reply + claim. A three-message chain needs the `choreographic-types` extension. +* *Recursion.* `mu`-types are outside the fragment. Stateful protocols with + loops are modeled as bounded unrollings, labelled `BOUNDED`. +* *Full merge.* Only plain merge. A protocol where a non-participant + distinguishes branches is outside the fragment. +* *Delegation.* Not modeled; a process cannot hand its endpoint to another. +* *Data-dependent warrants.* The frame carries what the type determines; a + digest-dependent claim is Layer A/C, not K-CUT. +* *Distribution.* Node partitions, `noconnection`, and message loss across nodes + are Phase 4. The async cut model is there; the OTP mapping is not. +* *Timers.* `GenServer` timeouts and `Process.send_after` are protocol events; + the MVP models them as uninterpreted events with a fairness assumption. +* *Dynamic supervisors.* `DynamicSupervisor`/`simple_one_for_one` create roles at + runtime, outside the finite-role model. +* *Runtime conformance.* The monitor is a test oracle, not a proof. A production + monitor could enforce the protocol at runtime, but that is a different + product. diff --git a/docs/architecture/QUINTESSENCE-LAYER-C.adoc b/docs/architecture/QUINTESSENCE-LAYER-C.adoc new file mode 100644 index 0000000..439f425 --- /dev/null +++ b/docs/architecture/QUINTESSENCE-LAYER-C.adoc @@ -0,0 +1,595 @@ +// SPDX-License-Identifier: CC-BY-SA-4.0 +// Copyright (c) 2026 Jonathan D.A.

Shape B reuses the receipt schema +but adds term-lifetime obligations (C9) that Rustler currently discharges. + +== The Idris2 QTT ABI + +The ABI module is the contract.

The `1` multiplicity on the +resource means the function consumes it exactly once and returns it; the caller +cannot duplicate or drop it. The `0` on the bounds and non-null proofs means they +are erased at runtime. The `Either String` return models every native error as +data; no exception crosses the ABI. + +=== The linearity gap + +`ResourceArc` is reference-counted and shared. Two Elixir processes can hold the +same `ResourceArc`; the BEAM does not enforce the Idris2 `1`. Rustler prevents +use-after-free because the refcount keeps the resource alive, but it does not +prevent two owners. Quintessence closes the gap at the stub: + +* the stub stores an ownership token `{owner_pid, ref, generation}` in the + resource; +* every NIF call checks `self() == owner_pid`, `ref` is live, and `generation` + matches; +* a transfer requires an explicit `transfer/2` that changes the owner under a + lock and increments the generation; +* a call from a non-owner returns `{:error, :not_owner}`. + +This is *stub-enforced linearity*, not kernel-proved linearity.

The receipt's `schedule` matches the Rustler `#[nif(schedule = ...)]` + annotation in the generated `nif_manifest.json`. +. The `MaxPlus` bound is consistent with the schedule (`normal` requires + `<= threshold`, `dirty_cpu` requires `> threshold` or an explicit override). +. The `budget_us` is <= the declared `@budget`. + +A mismatch is `Q-305`. There is no runtime "auto-dirty" switch; a NIF that is +too slow cannot be rescued by the stub. `schedule: :auto` in `@nif` is therefore +an assertion, not a choice: it says the stub accepts whatever schedule the build +compiled, provided the receipt agrees with it. + +== Load-time verification + +`use Quintessence.Nif` generates: + +[source,elixir] +---- +@on_load :__quintessence_load__ + +def __quintessence_load__ do + with {:ok, receipt} <- Quintessence.Receipt.read(@receipt), + :ok <- Quintessence.Receipt.validate_schema(receipt), + :ok <- Quintessence.Receipt.check_target(receipt), + :ok <- Quintessence.Receipt.check_binary(receipt, @library_path), + :ok <- Quintessence.Receipt.check_obligations(receipt), + :ok <- Quintessence.Receipt.check_schedule(receipt, @schedule), + :ok <- :erlang.load_nif(@library_path, 0) do + :ok + else + {:error, reason} -> {:error, reason} + end +end +---- + +Failure modes: + +[cols="1,2,2",options="header"] +|=== +| Code | Cause | Behaviour + +| `Q-301` | Receipt missing or unreadable | Module does not load. +| `Q-302` | `MaxPlus` bound exceeds budget or is `Unknown` | Module does not load. +| `Q-303` | Binary SHA-256 mismatch | Module does not load. +| `Q-304` | An obligation is not `proved` | Module does not load. +| `Q-305` | Schedule mismatch | Module does not load. +| `Q-306` | Target triple mismatch | Module does not load. +| `Q-307` | ABI module hash mismatch | Module does not load. +|=== + +The load check is not a proof; it is a supply-chain and build-consistency check. +It prevents a stale or substituted `.so` from being used with a receipt that +describes a different build. + +== Reproducible builds + +The receipt's `binary_sha256` is only meaningful if the build is reproducible. + +* Zig: `zig build-lib -static -Dtarget=x86_64-linux-gnu -Doptimize=ReleaseSafe`. + `ReleaseSafe` keeps bounds and overflow checks; `ReleaseFast` disables them, + so a `ReleaseFast` build requires a different receipt and a different + obligation set (or is rejected). +* Rust: `cargo build --release --locked`; `Cargo.lock` committed; Rustler version + pinned. +* Environment: `SOURCE_DATE_EPOCH`, `TZ=UTC`, `LC_ALL=C`, fixed paths via + `--remap-path-prefix`. +* The `.so` is hashed after stripping; the hash is written into the receipt and + into the release artifact manifest. + +A build that is not reproducible can still be verified, but the receipt is +labelled `reproducibility: unverified` and the NIF gate requires a manual +review. + +== Validation strategy + +. *Zig unit tests* for the core: empty payload, 1 MiB payload, 1 MiB + 1, + all-zero digest, all-ones digest, drift 0 and 10000. +. *Elixir integration tests* through the stub: successful call, error path, + stale receipt, tampered binary, wrong schedule. +. *Differential tests*: a pure Elixir reference implementation of BLAKE3 and + drift; random payloads; compare. +. *Fuzzing*: AFL++ or `zig build test` with a fuzz target; the fuzz corpus is + part of the repo. +. *Sanitizers*: ASan/UBSan for the C ABI; `valgrind` for the Rust glue; `miri` + for the Rust code where possible. +. *Receipt mutation*: ECHIDNA mutates the receipt (drop an obligation, widen the + bound, flip the schedule) and checks that the load fails. + +Validation does not replace the receipt. It catches integration bugs that the +proofs do not model, such as a Rustler version change that alters term encoding. + +== Open issues + +* *ZigProve interface.* The obligation names and proof format are an external + contract.

The IR's type checker is a total function. +* *Content-addressed.* Canonical serialization (I-JSON/JCS for the interchange + form, CBOR for the binary form), SHA-256 over the canonical bytes. Names are + resolved to fully qualified atoms before hashing; source locations are + excluded from the hash and carried as provenance. +* *Layer-neutral.* A `Term` has no Elixir syntax. `Send`, `Recv`, `Call`, and + `Cast` are protocol primitives; `NifCall` and `Budget` are native primitives; + `Secret` and `Declassify` are information-flow primitives. +* *QTT-aware.* Proofs are erased (`0`); linear handles are `1`; ordinary data is + unrestricted.

Sort checking (a term has exactly one sort; `SProtocol` only in Layer B, + `SCost` only in Layer C). +. Contract well-formedness (`pre`, `post`, `inv` are `SProp`; `measure` is + `SCost` or `SData`; `caps` is a subset of the module's declared footprint; + secret labels form a lattice element). +. Provenance attachment (every node gets `Origin`, including the macro path + recorded by G0). +. Canonicalization (alpha-renaming, literal normalization, map key ordering, + binary literal encoding). + +The elaborator is part of the TCB. The mitigation is not "trust us": it is a +small IR, a golden test corpus with hand-checked `.qir`, and a Phase 5 +proof-producing translation for the core fragment. Until then, the specification +says `elaborator: assumed` in the receipt. + +=== Why Idris2 + +* Dependent types let the IR's typing rules and the evidence objects live in the + same language as the proofs about them. +* QTT gives linearity for the ABI layer without a separate linear-logic + implementation. +* `%default total` matches the estate's proof discipline; the same gate rejects + `believe_me` and `postulate`. +* The checker can be compiled to a native binary and run offline; it does not + need to run on the BEAM. +* It is already the estate's ABI language (`src/interface/Abi` in this template), + so the boundary has one fewer translation. + +The alternative — a Rust IR with hand-written checkers — would be faster to +build but would put the IR's metatheory outside a proof assistant.

A function +outside the subset is not silently skipped: the elaborator emits `Q-201` with the +source location and the first unsupported construct. The author either rewrites +the function, moves it to a `@trusted` boundary with a receipt, or excludes the +module from `mix verify`. + +=== Types and refinements + +The base sorts are `integer`, `nat`, `boolean`, `atom`, `binary`, `bitstring`, +`list(a)`, `map(k, v)`, `tuple(a, b, ...)`, `struct(Module)`, `option(a)`, and +`result(a, e)`. Refinements are written `{x : T | phi}` and are generated from +`@pre`, `@post`, guards, and pattern matches. + +A pattern match refines the scrutinee in each branch.

The elaborator generates the +decrease obligations; Why3 discharges them with the same SMT portfolio. The +accepted measures are: + +* structural size of a list, map, binary, or tuple; +* a lexicographic combination of measures; +* a user-supplied `nat`-valued function whose decrease is proved. + +General recursion, mutual recursion without a lexicographic measure, and +`Enum.reduce` without a decreasing measure are rejected.

A NIF call is *not* projected into Layer A at all: a NIF is outside +the subset, and its stub is checked by Layer C against the same model. This is the +key discipline: Layer A proves the functional contract relative to the logical +model; Layer C proves the native implementation refines the model. Neither layer +assumes the other. + +=== Secrets and capabilities + +`@secret` labels every verified value with an element of the two-point (MVP) or +generic (Phase 4) lattice. The typing judgment is + +[source,text] +---- +Gamma |- e : {v : T | phi} @ ell ; Sigma +---- + +where `ell` is the confidentiality label and `Sigma` is the capability +footprint.

It is not enough to check each function in +isolation: the *product* of capabilities must not form an exfiltration corridor. +In Elixir terms, a process that holds both `:fs` and `:net` must not pass a value +derived from a file into a network send without a declassification. The +elaborator builds the footprint product for each process and checks the +corridor obligations.

The point of R5 is that a +future verified `read_file` and `send_socket` pair would still be rejected as a +composition unless the label flow is proved safe. + +The `@cap` footprint is an MPR `Sigma`: a finite map from capability names to +the resources they may touch. `File`, `System`, `Port`, and `Code.eval_*` are +ambient authorities and are absent from the default `Sigma`; a module that needs +them must say so and carry a receipt.

Data-level facts ("the digest +equals BLAKE3(payload)") belong in `@post`, where Layer A and Layer C prove them. +Mixing the two is the most common way to overclaim: the choreography library's +Kripke frame carries only what the type determines, and data-dependent warrants +are explicitly outside its proved fragment. + +=== Errors + +The Face fails at compile time with a source location, the attribute, and a +code. The important ones are: + +[cols="1,3",options="header"] +|=== +| Code | Meaning + +| `Q-201` | Construct outside the Layer A subset. +| `Q-202` | Non-exhaustive match or missing catch-all in a protocol handler. +| `Q-203` | Contract attribute is not a literal or a `spec(...)` expression. +| `Q-204` | Secret-to-public flow without `@declassify`. +| `Q-205` | `@cap` names a capability outside the module's declared footprint. +| `Q-206` | `@measure` is not `nat`-valued or does not decrease. +| `Q-207` | A construct has no projection into the target theory (Why3, TLA+, + or ZigProve), so no obligation can be stated for it. +| `Q-401` | Unwarranted remote claim: cast/send used as a causal reply. +| `Q-402` | Choreography is outside the proved K-CUT fragment (recursion, full + merge, n-ary choice, dynamic roles). +| `Q-403` | Protocol handler does not match the declared message shape. +| `Q-404` | Mailbox occupancy bound not proved and no backpressure declared. +|=== + +The Face is not a general-purpose specification language.

If a claim cannot be expressed in the IR, it cannot be expressed in +the Face. + +[[layer-b]] +== Layer B: OTP, mailboxes, crashes, and K-CUT + +A `GenServer` is a protocol endpoint. Its callbacks define a local type; its +messages define the interactions; its mailbox is a queue with a high-water mark; +its supervisor defines what happens when a cut is truncated by a crash. None of +this is visible to Dialyzer or the type system. + +Layer B maps the OTP fragment onto the graded choreographic types of +`choreographic-types`, checks the K-CUT obligations, and discharges the concrete +protocol with Apalache.

Each party +has a *view*: its local timeline up to the cut. Two worlds are indistinguishable +to a party when their views coincide. Knowledge is truth at every world the party +considers possible: + +[source,text] +---- +K_i(phi) at cut k iff phi holds at every world k' with view_i(k') = view_i(k) +---- + +`choreographic-types` proves two families for the finite, binary-choice, +plain-merge fragment, synchronous and asynchronous: + +* *K-CUT-LOSS* (`KCut.kcut-loss`, asynchronous `Async.akcut-loss`): grading + commutes with endpoint projection across a consistent cut. In English: the + global grade restricted to a party equals the grade the party can read from its + own view. This is an equality, parametric in the resource algebra, and is + discharged at the `Loss`, `MaxPlus`, and `HWM` instances. +* *K-CUT-WARRANT* (`Bound.knows-lower-bound`, `knows-upper-bound`, + `Transport.knows-local-cut`): a party knows its own restricted grade and a + one-sided bound on the global grade; knowledge is monotone along the party + access preorder. It is a *bound*, not an equality, and the direction depends on + where the algebra's unit sits in its order. + +The pre-registered falsifier is confirmed: +`AsyncKnowledge.sender-cannot-know-receipt` proves that, after an asynchronous +send, the sender does not know the receiver received it. The dual +`AsyncKnowledge.receiver-knows-sent` proves the receiver does know it was sent. +A reply restores the sender's knowledge, but only for the two-message protocol +`0 -> 1 : a . 1 -> 0 : b` (`Instances.reply-gives-knowledge`). The general reply +chain, position-indexed form, recursion, and full merge are *open*. + +This is the single most important boundary in the design. Quintessence MUST NOT +claim more than the library proves: + +[cols="3,3,2",options="header"] +|=== +| Claim | Status in `choreographic-types` | Quintessence may + +| After `call` and its reply, the caller knows the server received the request. +| Proved for the two-message protocol (`Y-8`). +| Emit a K-CUT-WARRANT obligation and accept a `call`-based claim. + +| After `cast`, the sender knows the receiver received it. +| Refuted (`Y-6`). +| Reject with `Q-401`; no escape hatch in `--strict`. + +| After a three-message chain, the first sender knows the third party received. +| Open (general reply chain). +| Not claim; require a direct reply or mark the claim `assumed`. + +| The caller knows the *payload digest* the server computed. +| Data-dependent warrants are outside the frame. +| Prove the digest functionally in Layer A/C; do not call it K-CUT knowledge. + +| A recursive protocol's knowledge invariant. +| Recursion is outside the fragment. +| Reject (`Q-402`) or model a bounded unrolling and label it `BOUNDED`. +|=== + +=== Mailbox occupancy + +A mailbox is not a channel in the session-type sense, but it has the same +resource shape: a bounded queue whose high-water mark is a grade. The design uses +two separate grades and refuses to identify them: + +* `HWM` is an occupancy grade: how many messages are live at a cut. Its monoid is + not max-plus; `occupancy-types` says so explicitly, and + `choreographic-types` proves K-CUT-LOSS at the `HWM` instance. +* `MaxPlus` is a cost grade: how long a handler or NIF takes. It is the + `tropical-types` algebra (Lean) and the `choreographic-types` `MaxPlus` + instance (Agda). They are the same algebra in name and laws, but the Lean-to-Agda + bridge is open; the two discharges are separate evidence, not one. + +The mailbox obligation is: + +[source,text] +---- +len(mailbox(pid)) <= HWM(pid) for every reachable state +HWM(pid) <= Cap(pid) for every declared capacity +---- + +`HWM` is derived from the protocol's occupancy grade at the cut, plus the +operational queue discipline. The elaborator emits: + +. A K-CUT-LOSS instance for the `HWM` algebra, so the global protocol's occupancy + bound projects to each role. +. A per-process queue model: arrival curve `alpha`, service curve `beta`, and the + backlog bound `sup_t (alpha(t) - beta(t))`. For a simple rate/burst model this + is `B + lambda * W`, where `W` is the worst-case handler latency from Layer C's + `MaxPlus` bound. +. A selective-receive check. `receive` scans the mailbox in order; unmatched + messages stay. For each pattern class, the checker computes the effective + service rate and proves no class starves. A handler with a catch-all `receive` + that never matches a class is a starvation bug, not a bound. +. A backpressure obligation. If the bound cannot be proved, the spec MUST use a + bounded internal queue with `handle_continue` or a `call`-based handshake; an + unbounded mailbox is `Q-404`. + +The MVP's mailbox model is single-node, crash-stop, and fair. Distributed +mailboxes, `noconnection`, and partitions are Phase 4; the K-CUT-LOSS layer +already models messages in flight, so the semantics are there, but the OTP +mapping is not. + +=== Crashes, links, and supervision + +A crash truncates the cut. Messages in flight to the crashed process are lost; +messages it had sent are still in other mailboxes; its state is gone. This is +exactly the loss/reorder model of the asynchronous K-CUT layer, with one +additional event: a new incarnation with a fresh epoch. + +* `monitor`/`:DOWN` gives the monitor knowledge of termination, not of state. +* `link` propagates exits; a trapping process receives `{:EXIT, pid, reason}`, + which is a signal, not a state commitment. +* `one_for_one` restarts one child; the rest of the system sees a new pid/epoch. + Any invariant that mentions the child's state must be re-established by + `init/1`, or carried by a durable receipt. +* `rest_for_one` and `one_for_all` restart a suffix/all of the tree; the cut is + global. The proof must show the invariant is inductive over the restart, not + just over normal transitions. +* `max_restarts`/`max_seconds` escalation terminates the subtree. The spec MUST + state whether that is a permitted outcome; it is not silently ignored. + +The Face's `@invariant` is checked at `init/1` (establishment) and at every +handler (preservation). A restart re-runs the establishment obligation. If the +invariant depends on state that is not rebuilt, the obligation fails; this is the +desired behaviour. + +=== Apalache + +The concrete protocol is emitted as a TLA+ module and checked by Apalache for a +bounded instance. The encoding is deliberately small: + +[source,tlaplus] +---- +VARIABLES state, mailbox, inflight, view, epoch, committed + +Init == + /\ state = [r \in Roles |-> InitState(r)] + /\ mailbox = [r \in Roles |-> <<>>] + /\ inflight = {} + /\ view = [r \in Roles |-> <<>>] + /\ epoch = [r \in Roles |-> 0] + /\ committed = [r \in Roles |-> {}] + +Send(i, j, msg) == + /\ i # j + /\ Len(mailbox[j]) < MaxMailbox + /\ mailbox' = [mailbox EXCEPT ![j] = Append(@, msg)] + /\ inflight' = inflight \cup {<>} + /\ UNCHANGED <> + +Deliver(j, msg) == + /\ msg \in inflight + /\ mailbox' = [mailbox EXCEPT ![j] = Tail(@)] + /\ view' = [view EXCEPT ![j] = Append(@, msg)] + /\ inflight' = inflight \ {msg} + /\ UNCHANGED <> + +Commit(j, v) == + /\ state' = [state EXCEPT ![j] = NextState(@, v)] + /\ committed' = [committed EXCEPT ![j] = @ \cup {v}] + /\ UNCHANGED <> + +NoUnwarrantedRemoteClaim == + \A r \in Roles, f \in committed[r] : + f \in committed[r] => HasWarrant(r, f) +---- + +Apalache checks `TypeOK`, `MailboxBound`, `NoUnwarrantedRemoteClaim`, and the +protocol's state invariant for a fixed `MaxMailbox`, `MaxEpochs`, and message +bound. The result is labelled `BOUNDED`. It is a bug finder and a consistency +check on the encoding, not a proof for all executions. The unbounded argument is +the K-CUT typing derivation plus the occupancy bound; Apalache checks that the +concrete protocol does not have a short counterexample the abstraction missed. + +=== What Layer B proves + +The composition theorem is the target, not a theorem of the current MVP: + +[source,text] +---- +If + (1) every Layer A handler satisfies its contract, + (2) the protocol is well-typed in the proved K-CUT fragment and every + knowledge claim has a warrant, + (3) the mailbox occupancy bound is proved (or backpressure is present), + (4) every NIF receipt is valid and its MaxPlus bound is within budget, +then + no reachable state violates the module invariant, and + no actor makes an unwarranted remote claim. +---- + +The proof is an induction over cuts: Layer A gives each local transition; K-CUT +gives projection and knowledge; the occupancy bound gives queue safety; Layer C +gives the native refinement. The induction is *not* machine-checked as a whole in +the MVP; the K-CUT metatheory is, and the concrete protocol is model-checked. +Closing the composition theorem in Agda is a Phase 5 work package. Until then, +the receipt records `composition: assumed` and `apalache: bounded`. + +[[layer-c]] +== Layer C: the verified Elixir-Idris2-Zig boundary + +A NIF is the one place where an Elixir program can corrupt the runtime.

Two QEDs promote the + Warrant to a Receipt at Level 5. + +The honest consequence: an SMT `unsat` with no certificate is *not* verification +evidence in quintessence. It is a strong hint. The MVP may run in +`--allow-oracle` mode for ordinary Layer A, but that mode stamps every affected +goal `oracle: true` and cannot produce a Receipt. + +=== Vacuity and mutation + +A proof of a vacuous specification is worthless. Quintessence checks vacuity in +four independent ways. + +[cols="1,2,3",options="header"] +|=== +| Probe | Question | Failure + +| V1: antecedent satisfiability +| Is there any input that satisfies `@pre`? SMT is asked for a model of the + conjunction of preconditions. +| `Q-601 VACUOUS`: the precondition is unsatisfiable. + +| V2: postcondition non-triviality +| Is the postcondition true for every result, independently of the body? The + checker tries to prove `post` with the body replaced by an uninterpreted + function. +| `Q-602 TRIVIAL`: the postcondition does not constrain the implementation. + +| V3: mutation score +| Do weakened versions of the specification fail to verify? +| `Q-603 WEAK_SPEC`: the score is below the threshold (default 95%). + +| V4: protocol reachability +| Does the choreography have a reachable state satisfying its goal? Apalache is + asked for a witness. +| `Q-604 VACUOUS_PROTOCOL`: no reachable state; the protocol proves nothing. +|=== + +The mutation engine is ECHIDNA's `verification::mutation` module. Its public +surface is `MutationTester`, `MutationKind`, `MutationResult`, +`MutationTestSummary`, and `meets_target(threshold)`; the default target is 95%. +The six built-in kinds are `RemovePrecondition`, `WeakenPostcondition`, +`AddDisjunct`, `RemoveHypothesis`, `ReplaceConstant`, and `NegateSubterm`. +Quintessence maps its IR goals onto `echidna::core::Term` and adds a +layer-specific plan: + +[cols="2,3,3",options="header"] +|=== +| Layer | Additional mutants | Why + +| A +| Swap `and`/`or`; drop a match arm; off-by-one on a numeric literal; replace + `==` with `!=`; replace `:ok` with `:error`; drop a `@declassify`. +| These are the defects a functional postcondition should catch. + +| B +| Replace `call` with `cast`; drop a reply; reorder independent messages; delay a + reply past a timeout; restart a process at a cut. +| These are the protocol defects K-CUT and Apalache should catch. + +| C +| Widen a `MaxPlus` bound; change `dirty_cpu` to `normal`; drop a receipt + obligation; swap a `u32` for a `u64`; remove a bounds check. +| These are the boundary defects the receipt should catch. +|=== + +The score is computed over *proof-relevant* obligations only. A `@pre` that the +proof never uses is a runtime guard, not an assumption; removing it cannot make +the proof fail. Such a precondition is marked `guard: true` and is validated by +tests, not counted as a mutation survivor. Without this distinction, the metric +rewards adding irrelevant preconditions. + +A worked failure: the postcondition `result.digest != the empty binary` is +weaker than `result.digest == digest_of(payload)`. The mutant that replaces the +latter with the former survives, because every non-empty digest satisfies the +weak version. + +The score drops below 95%, the report names the surviving mutant and the +postcondition it weakened, and the author strengthens the postcondition. That is +the intended loop. + +[[worked-example]] +== Worked dual example: a VeriSimDB entity + +The example is in link:../../examples/quintessence/README.adoc[`examples/quintessence/`]. +It is a single GenServer, a single NIF, and a single three-role protocol, chosen +to exercise all three layers without hiding behind a framework. + +=== The entity + +[source,elixir] +---- +defmodule Verisim.Entity do + use GenServer + use Quintessence.Face, layer: :b + + @max_payload 1_048_576 + @max_drift_bp 2_500 + + @cap [read: [:entity], write: [:entity], + call: [{Verisim.Nif, [hash: 2, drift: 2]}]] + @secret [payload: :confidential, digest: :public, drift: :public] + @declassify digest: :public, reason: :commitment + @invariant spec(new_state.version >= old.version) + @budget hash: 180, drift: 240 + + @choreography [ + roles: [:client, :entity, :auditor], + messages: [ + {:client, :entity, :commit, [:payload]}, + {:entity, :client, :committed, [:version, :digest]}, + {:entity, :auditor, :attest, [:version, :digest]} + ], + knowledge: [ + {:client, :entity, :committed, [:version, :digest], {:call, :commit}}, + {:auditor, :entity, :attest, [:version, :digest], {:cast, :attest}} + ], + forbid: [ + {:entity, :knows, {:auditor, :received, :attest}, :cast} + ] + ] + + @impl true + @role :entity + @handles {:call, :commit} + @pre spec(byte_size(payload) <= @max_payload) + @pre spec(state.status == :active) + @post spec( + case result do + {:ok, _, _} -> + new_state.version == old.version + 1 and + new_state.digest == Verisim.Spec.digest_of(payload) and + new_state.drift <= @max_drift_bp + {:error, _} -> + new_state == old + end + ) + def handle_call({:commit, payload}, _from, state) do + case Verisim.Nif.hash(payload, state.version) do + {:ok, digest} -> + drift = Verisim.Nif.drift(state.digest, digest) + + if drift <= @max_drift_bp do + new_state = %{state | version: state.version + 1, digest: digest, drift: drift} + {:reply, {:ok, new_state.version, new_state.digest}, new_state} + else + {:reply, {:error, :drift}, state} + end + + {:error, reason} -> + {:reply, {:error, reason}, state} + end + end + + @impl true + @role :entity + @handles {:cast, :attest} + @post spec( + case result do + :ok -> new_state == old + _ -> new_state == old + end + ) + def handle_cast({:attest, _version, _digest}, state) do + # The entity sends an attestation to the auditor.

Three layers, one IR, one evidence ladder + +Date: 2026-10-22 + +=== Status + +Accepted. The decision is about the *shape* of the verification suite; it does +not assert that any layer is implemented. Implementation status is tracked in +link:../status/QUINTESSENCE-ROADMAP.adoc[the roadmap]. + +=== Context + +Elixir code mixes three kinds of claim that need three different logics: + +. A pure function's postcondition is a statement about *all* inputs of a + sequential program. SMT and Why3 are the mature route. +. A `GenServer`'s knowledge of a remote commit is a statement about *messages, + cuts, and causality*. A sequential logic cannot express it, and a type checker + cannot prove it. +. A NIF's safety is a statement about *memory, ABI layout, and time*. It needs a + linear type discipline for handles and a cost bound that the BEAM scheduler + understands. + +The estate already contains the theory for the second and third: an Agda +`choreographic-types` development with K-CUT results, a Lean `tropical-types` +development with a `MaxPlus` resource semiring, `occupancy-types` for step +bounds, and `secret-types`/`epistemic-types` for information flow and knowledge. +It also contains ECHIDNA, which already knows how to dispatch a goal to an SMT +portfolio, check a certificate, track axioms, and compute a trust level. + +The rejected alternative was a single tool for "all of Elixir". Every such tool +either (a) proves only the pure fragment and silently ignores the rest, or +(b) models the OTP layer as a state machine and loses the knowledge semantics +that make a `cast` claim false. Both failure modes are worse than a narrow tool +that states its boundary. + +=== Decision + +1. *Three layers, one IR.* The front end filters Elixir through a deterministic + macro firewall, checks a sequential subset, and elaborates the surviving + modules plus the Face attributes into one small, total, content-addressed + Idris2 Core Spec IR (`qir/v1`). All three layers consume the same IR; none + re-parses Elixir. +2. *Each layer has one theory and one checker.* Layer A: Why3/SMT, with a + strict Dedukti witness for the decidable fragment. Layer B: the pinned + `choreographic-types` K-CUT results plus Apalache for a bounded instance + check. Layer C: the Idris2 ABI/QTT specification, the ZigProve receipt, and + the `tropical-types` `MaxPlus` bound. +3. *Evidence has two forms.* A local, content-addressed *Warrant* is + `incomplete` until the batch stage rechecks it in Coq and Lean; a *Receipt* + is the batch-checked object and is the only thing a release gate accepts. +4. *The trust ledger is explicit.* Every imported library, checker, and + assumption is listed with what it is trusted for and what breaks if it is + wrong. Where a library is partial (for example, `occupancy-types` does not + grade high-water marks in v0), the document says so and the composition is + marked as an assumption rather than a theorem. +5. *The boundary is enforced, not documented.* `Code.eval_*`, dynamic + `apply/3`, unverified NIFs, and cross-process knowledge claims without a + causal reply are *compile-time errors*, not lint warnings. + +=== Consequences + +==== Positive + +- Each layer can be validated independently: the IR round-trips, the Layer A + VCs are SMT-sized, the Layer B instance is finite, and the Layer C receipt is + a JSON object with a binary hash. +- The pinned estate libraries are reused rather than re-derived. The K-CUT + metatheory stays in Agda; the `MaxPlus` algebra stays in Lean; quintessence + builds adapters, not parallel theories. +- A missing tool or a stale receipt fails closed at `mix quintessence.doctor` or + at NIF load time, so "not verified" cannot be mistaken for "verified". +- The same IR makes cross-layer claims checkable: a `@choreography` attribute and + a `@nif` budget refer to the same obligation graph. + +==== Negative + +- Three logics mean three failure vocabularies. The error-code ranges + (`Q-1xx` to `Q-9xx`) and the single `mix verify` report exist to hide that + complexity from the user, but the implementer pays for it. +- The Layer B fragment is deliberately small: finite global types, binary + choice, plain merge, and the two-message reply theorem. A three-party reply + chain is `assumed` until the library extension lands; the tool must say so. +- The Dedukti route for Layer A is a named TCB component until Phase 5 proves + the translation, so early receipts carry an explicit assumption. +- A Receipt is expensive: batch Coq and Lean checks dominate CI time. Caching + and `--replay` are required, not optional. + +==== Neutral + +- The worked example is a `VerisimDB`-style entity because that domain has a + natural digest, a natural drift metric, and a natural two-message protocol. + The choice is illustrative, not normative. +- `mix verify` is the only entry point. Editors and CI call it; no second + pipeline is permitted. + +=== Alternatives considered + +* *Dialyzer plus set-theoretic types.* Rejected as a proof: both are sound + approximations that warn, and neither expresses a postcondition or a + knowledge claim. They remain useful as a first filter and are cited as the + baseline in the contrast section of the architecture document. +* *Property-based testing only.* Rejected: PropEr and StreamData sample; they do + not quantify over all inputs, and a passing property is not a receipt. +* *Concuerror as the protocol checker.* Rejected as the primary route: it + explores schedules within a bound and cannot state "the caller does not know + the replica committed". It is retained as a validation tool for the Apalache + counterexamples. +* *Rust-only verification (Prusti/Creusot) for the NIF.* Rejected: the ABI and + the scheduler bound are Elixir/BEAM facts, and the estate's ZigProve receipts + already carry the memory obligations. Rustler glue is kept deliberately thin. +* *One monolithic Coq development.* Rejected: it would re-derive the estate + libraries and lose the ability to pin them independently. + +=== References + +* link:../architecture/QUINTESSENCE.adoc[Quintessence: architecture and MVP roadmap] +* link:../architecture/QUINTESSENCE-LAYER-A.adoc[Layer A] +* link:../architecture/QUINTESSENCE-LAYER-B.adoc[Layer B] +* link:../architecture/QUINTESSENCE-LAYER-C.adoc[Layer C] +* link:../architecture/QUINTESSENCE-EVIDENCE.adoc[Evidence] +* link:../status/QUINTESSENCE-ROADMAP.adoc[Roadmap] diff --git a/docs/decisions/README.adoc b/docs/decisions/README.adoc index cb9c6d8..4ce9a6d 100644 --- a/docs/decisions/README.adoc +++ b/docs/decisions/README.adoc @@ -1,3 +1,38 @@ // SPDX-License-Identifier: CC-BY-SA-4.0 -// Copyright (c) Jonathan D.A.

If the fragment is + too small, the release gate has too many `UNCHECKED` goals. +* Elixir AST drift across 1.19/1.20; pin and test. +* The macro sandbox may break legitimate macros; the allowlist must be reviewed + with the application team. +* TINI for Elixir is not the same as TINI for a `while` language; the adapter + must model Elixir's evaluation order and implicit flows carefully. + +== Phase 2: Layer C (weeks 8-14) + +=== Deliverables + +* Idris2 ABI module for one NIF (`Verisim.Abi`): state-indexed handle, linear + resource, `Buffer`, `Digest`, `Drift`, `%foreign` signatures. +* Zig core (`verisim_hash`, `verisim_drift`), allocation-free, no globals, no + `@cImport`. +* Rustler wrapper: `ResourceArc`, term decoding, error mapping, schedule + annotation. +* ZigProve adapter: receipt schema, obligation mapping, binary hash, target, + `optimize` flag. +* `MaxPlus` binder: cost AST, straight-line and bounded-loop rules, Lean checker + importing `tropical-types`, threshold/margin decision. +* `@nif` stub and `@on_load` receipt checks;

callback coverage; bytecode call audit (`GenServer.call` vs + `cast`). +* K-CUT static checker: K-SEND, K-CAST, K-RECV, K-CALL, K-REPLY, K-MON, + K-RESTART; `Q-401` for unwarranted claims; `Q-402` outside the fragment. +* Agda instance emission for the two-message protocol; import + `choreographic-types` at the pinned SHA; check with `--safe --without-K`. +* Occupancy: HWM grade from the protocol; arrival/service bound; selective + receive check; backpressure obligation. +* Apalache: TLA+ model, `NoUnwarrantedRemoteClaim`, `MailboxBound`, + `EpochConsistent`; bounded run in CI. +* Runtime conformance monitor for tests; trace replay. +* Worked example end to end. + +=== Exit criteria + +* The worked example passes with a Level 4 Agda instance and a `BOUNDED` + Apalache run. +* A cast-based remote claim is rejected with `Q-401` and the falsifier name. +* A mailbox that exceeds its HWM in the model produces a counterexample; the + Elixir replay reproduces it. +* A protocol outside the fragment (recursion, full merge) is rejected with + `Q-402`, not approximated. +* The K-CUT instance is checked by Agda at the pinned library revision. + +=== Risks + +* The two-message fragment may be too narrow for the first real protocol; the + fallback is to add a direct reply, not to widen the claim. +* Apalache state explosion; bound the model and label it `BOUNDED`. +* The runtime monitor may be expensive; sample or test-only. +* The Face can lie about callbacks; the bytecode audit and monitor are the + independent checks. + +== Phase 4: Layer B1 and distribution (weeks 20-28) + +=== Deliverables + +* Co-develop the general reply-chain theorem with `choreographic-types` + (position-indexed Y-5/Y-6, general Y-8). +* Binary choice in the Face (`choices:`) if the library fragment supports it. +* Restart epochs and `ProofTransport` certificates; durable state receipts. +* Distributed loss: node partitions, `noconnection`, timeouts; async cut model. +* Occupancy-types integration: Session IR checker for the mailbox discipline; + HWM algebra alignment with `choreographic-types`. +* Dirty-pool concurrency bound; `MaxPlus` for allocating cores (Phase 2 + extension). + +=== Exit criteria + +* A three-message protocol is either proved by the extended library or + explicitly `assumed`; no claim exceeds the library. +* A restart during an in-flight reply invalidates the knowledge claim unless a + durable receipt matches the epoch. +* A partition is modeled as loss; the sender's ignorance is `Q-401`. +* A concurrent NIF pool has a proved concurrency bound. + +=== Risks + +* The library extension may not land; the MVP stays at two messages. +* Distributed testing is expensive; use a deterministic simulator first. +* `occupancy-types` is early-stage; the integration may require co-development. + +== Phase 5: evidence hardening (weeks 28-36) + +=== Deliverables + +* Prove the `why3-dk` translation for the decidable fragment, or keep + `translation: assumed` and restrict the release gate. +* `transport` batch mode: `.dk` to Coq/Lean, checked. +* Composition theorem in Agda: Layer A/B/C interfaces, induction over cuts. +* Coq/Lean instance cross-check for Layer B (finite protocol), Level 5. +* Full mutation plan (Layer A/B/C), V3/V4, guard/type-only classification. +* Signed receipts, revocation list, reproducible build manifest. +* `mix verify --strict --receipt` release gate; independent audit. + +=== Exit criteria + +* A Receipt is reproducible from the `.qir` and the tool pins alone. +* The composition theorem is machine-checked, or the receipt says + `composition: assumed` and the release gate refuses the claim. +* The independent audit reproduces the example receipt and finds no overclaim. +* No `UNCHECKED` obligation in the release path; `--allow-oracle` cannot produce + a Receipt. + +=== Risks + +* Proving the translation is a research project; if it slips, keep the TCB + label and narrow the release claim. +* Coq/Lean batch cost; cache and incremental checking. +* Audit capacity;

The auditor's claim is the receiver-side half of the third message; it +is allowed because the auditor is the receiver. The entity's claim about the +auditor is *not* allowed: there is no reply. The `forbid` entry in +`lib/verisim/entity.ex` makes that explicit, and the checker rejects the module +if a future edit adds the claim. + +This is the difference between "the message was sent" and "the message was +received". A `cast` is not a commit. A `call` reply is a warrant only when the +reply is causally after the commit and carries the version/epoch. + +=== Why the TLA+ module has a different name + +`QuintessenceKCut` is the *pattern*: cuts, views, warrants, and the two +invariants, parametric in `Roles`, `Values`, `MaxMailbox`, and `MaxEpochs`. +`VerisimEntity` is one *instance* of that pattern for the three-role protocol in +this example. Apalache checks the instance, because a finite model is what a +model checker can check; the pattern document (`QUINTESSENCE-LAYER-B.adoc`) states +which parts of the pattern are proved in Agda and which are assumptions. + +== The NIF, and the scheduler decision + +The stub declares `schedule: :auto`; the receipt says `normal` with a bound of +240 us. `use Quintessence.Nif` checks, at load time: + +. The receipt schema and target. +. The `.so` SHA-256 against `binary_sha256`. +. Every obligation is `proved` (12/12). +. The `MaxPlus` bound is within the budget and threshold. +. The schedule matches the Rustler annotation. + +A 1.4 ms NIF would produce `bound_us: 1400` and `schedule: dirty_cpu`; the stub +would load it only if the Rustler annotation was `DirtyCpu`. A 1.4 ms NIF with a +`normal` annotation is `Q-305`. A 1.4 ms NIF with a 1 ms budget is `Q-302`. + +The `MaxPlus` expression is `max(180, 240) = 240`: choice is `max`, sequence is +`+`.
