derived-memory boundary needed by the durable +agent loop. It adds three orchestration-layer crates: + +- `peritus-role`, a verified projection from B1 security roles into context visibility, + contribution, freshness, and presentation policy; +- `peritus-context`, a verified provenance graph, deterministic selector, token-budget planner, + compaction validator, and provider-neutral render-plan builder; and +- `peritus-memory`, a verified scoped-memory lifecycle, evidence/confidence model, deterministic + retrieval planner, quarantine/forgetting behavior, tombstones, and rebuildable index model. + +These crates are control-plane libraries. They do not invoke models, execute tools, mutate +workspaces, persist records, or issue capabilities. D0 will combine their immutable plans with C4 +tools, C5 provider profiles, and C0 durable records. + +The preferred architecture keeps the three crates separate. `peritus-role` is frozen first. +`peritus-context` and `peritus-memory` then build independently against that contract, with their +integration expressed through immutable, provenance-preserving candidate data. This is preferred +over a single context/memory crate because selection, compaction, retention, and retrieval evolve +at different rates and need independent tests and ownership. + +The design verdict is **ready for implementation**. The architecture, authority boundary, +dependency direction, failure behavior, and acceptance evidence are fully specified below. + +## User-visible behavior + +C6 has no direct CLI surface, but it defines behavior that future CLI, daemon, and agent-loop +surfaces must expose consistently: + +1. Every piece of model-visible context has explicit provenance, authority class, trust class, + digest, token estimate, recency, role visibility, and dependency edges. +2. Selection is deterministic for identical inputs. Required content is either included with all + required dependencies or rejected with a typed reason; it is never silently omitted. +3. Application/system policy and immutable specification material outrank derived memory, tool + output, repository content, and external material. Lower-authority text remains inert content + even when it contains instruction-like language. +4. Context planning honors an explicit input-token budget and reserves output/headroom tokens. + Budget failure identifies required items responsible for the failure. +5. Compaction is a validated derivation, not an in-place rewrite. A compacted node cites its + source ranges and policy revision; protected policy/specification nodes cannot be summarized. +6. A render plan preserves boundaries and provenance. It contains ordered, typed segments rather + than a single concatenated prompt and remains provider-neutral. +7. Memory records are scoped, evidence-backed derived claims. Retrieval is deterministic and + explainable through component scores and exclusion reasons. +8. Expired, quarantined, forgotten, unsupported, or out-of-scope memories are not injected. +9. Forgetting emits a tombstone that suppresses the record during replay and index rebuild. +10. A reviewer receives a fresh, read-only context view that excludes producer-hidden reasoning. + A writer, fixer, evaluator, and evolution agent receive different context views without + changing the B1 role's operation permissions. + +## Requirements + +### Role policy + +- **C6-R001:** `peritus-role` shall use `peritus_policy::ActorRole` as the canonical role identity + and shall not define a competing security-role enum. +- **C6-R002:** Each supported harness role shall have a deterministic context policy covering + visible provenance classes, allowed contribution classes, required context classes, freshness, + hidden-reasoning visibility, memory visibility, and presentation profile. +- **C6-R003:** Capability views shall contain only operation classes permitted by + `ActorRole::permits_operation`; the crate shall not issue, consume, widen, or persist B1 + capabilities. +- **C6-R004:** Reviewer policy shall require fresh context, prohibit producer-hidden reasoning and + memory-derived producer rationale, and expose B2 independence requirements without weakening + them. +- **C6-R005:** Writer and fixer roles shall not receive acceptance, waiver, policy-amendment, or + harness-promotion capability views. Reviewer and evaluator roles shall not receive workspace + mutation capability views. +- **C6-R006:** Unsupported B1 service/worker/plugin roles shall receive explicit restricted + profiles rather than being silently mapped to a privileged harness role. + +### Context graph and selection + +- **C6-R010:** Every `ContextNode` shall have a stable node identifier, content digest, + provenance, authority, trust, content kind, token estimate, recency sequence, requirement mode, + role-visibility set, and canonically ordered dependency identifiers. +- **C6-R011:** Constructors shall reject zero token estimates, duplicate dependencies, + self-dependencies, noncanonical dependency/visibility order, and inconsistent + provenance/authority/trust combinations. +- **C6-R012:** The graph constructor shall reject duplicate node identifiers, missing + dependencies, and dependency cycles. +- **C6-R013:** Selection shall be deterministic and stable. Required closure is selected first; + optional nodes are ranked by authority, requirement, explicit priority, recency, and stable + identifier tie-breaks. +- **C6-R014:** A selected node shall imply selection of its complete dependency closure. +- **C6-R015:** Nodes hidden from the selected role shall never appear in selection or rendering. +- **C6-R016:** A required node that is hidden, missing a visible dependency, or cannot fit shall + produce a typed planning error. Selection shall not return a partial success. +- **C6-R017:** Token arithmetic shall be checked. The plan shall separately report context-window + capacity, reserved output, reserved protocol overhead, usable input, used input, and remaining + input. +- **C6-R018:** Optional groups that cannot fit with their full dependency closure shall be omitted + atomically with an explainable reason. + +### Compaction and rendering + +- **C6-R020:** A compaction proposal shall name a new derived node, the compaction-policy digest, + and a canonically ordered list of nonempty source ranges. +- **C6-R021:** Compaction validation shall reject missing sources, range errors, overlapping or + noncanonical ranges, digest mismatches, source cycles, hidden sources, and output estimates that + are not smaller than the replaced selected material. +- **C6-R022:** System policy, application policy, immutable specifications, active user + instructions, capability facts, and unresolved blocking findings shall be protected from + summarization. +- **C6-R023:** A validated compacted node shall retain `DerivedCompaction` provenance, untrusted + trust unless every input is trusted and policy permits trust preservation, and dependency links + to every source node. +- **C6-R024:** Rendering shall preserve segment role, provenance, authority, trust, digest, and + content kind. It shall never promote repository, external, memory, tool, agent, or review text + to system/application authority. +- **C6-R025:** Render ordering shall be deterministic and respect precedence while keeping each + node as a separate segment. Provider-specific message encoding belongs to D0/C5 integration. + +### Memory lifecycle and retrieval + +- **C6-R030:** A `MemoryRecord` shall contain a stable identifier, scope, source event set, claim + type, content digest, confidence, supporting evidence, contradicting evidence, creation/review + observations, optional expiry, retrieval features, lifecycle state, and revision. +- **C6-R031:** Memory constructors shall reject empty source sets, empty scopes, invalid bounded + scores, noncanonical evidence/features, evidence present in both supporting and contradicting + sets, expiry before creation, and zero revisions. +- **C6-R032:** Memory shall always be derived, non-authoritative context. No memory API shall + return a B1 capability, authority transition, acceptance decision, waiver, specification + amendment, or harness promotion. +- **C6-R033:** Lifecycle transitions shall be explicit and checked: active memories may be + reviewed, quarantined, expired, superseded, or forgotten; forgotten memories are terminal and + produce a tombstone; quarantine release requires a later review observation and revision. +- **C6-R034:** A tombstone shall bind memory identifier, last known revision, deletion observation, + reason, and prior digest. Replay shall make deletion win over records at or below that revision. +- **C6-R035:** Retrieval shall filter by exact scope compatibility, role policy, lifecycle, + quarantine, expiry, minimum confidence, required features, and tombstones before ranking. +- **C6-R036:** Ranking shall be deterministic using bounded integer components for scope + specificity, relevance, confidence, evidence balance, recency, and feedback. Stable identifier + order shall break equal scores. +- **C6-R037:** Retrieval shall return an explanation for every candidate: selected with component + scores, or excluded with a typed reason. Selected total estimated tokens shall not exceed the + query budget. +- **C6-R038:** Negative feedback, contradiction, and stale review shall reduce ranking or trigger + quarantine under explicit policy; they shall not be discarded silently. +- **C6-R039:** Indexes shall be derived from canonical records and tombstones. Rebuild from the + same ordered input shall produce the same active index and digest. +- **C6-R040:** Memory text originating in repositories, tools, providers, or external sources + shall retain that provenance when materialized as context and shall be delimited as quoted + evidence, never executable instructions. + +### Engineering and verification + +- **C6-R050:** All deterministic validation, ranking, selection, lifecycle, and budget logic that + Verus can express shall live in Verus-verified code with executable postconditions or proof + obligations. +- **C6-R051:** Public structs shall keep fields private and expose checked constructors and + read-only accessors. Errors shall be typed, stable, actionable, and comparable in tests. +- **C6-R052:** Production source shall contain no `unsafe`, reachable placeholder success path, + `todo!`, ambient I/O, global mutable state, wall-clock lookup, provider call, or effect handle. +- **C6-R053:** Each crate shall keep the root module below 80 lines, ordinary source files below + the 400-line soft limit where practical and below the 700-line hard limit without exception. +- **C6-R054:** The crates shall pass formatting, build, all-target/all-feature tests, strict + Clippy, rustdoc warnings, architecture, ordinary-API audit, focused no-cheating Verus + verification, and verified release build. + +## Acceptance criteria + +| Criterion | Required evidence | +|---|---| +| Role policies cannot widen B1 roles | exhaustive role/operation matrix tests and Verus proof that every projected operation is B1-permitted | +| Review context is fresh and independent | reviewer profile tests plus B2 independence projection tests | +| Graphs are valid and selections deterministic | construction failure matrix, permutation/property corpus, exact golden plans | +| Required context is never silently lost | hidden/missing/cyclic/over-budget tests proving typed failure | +| Token plans are bounded | boundary and overflow tests plus verified arithmetic postconditions | +| Compaction preserves provenance and protected content | full proposal rejection matrix, successful lineage fixture, poisoning corpus | +| Rendering preserves authority boundaries | exact render-segment fixtures and precedence tests | +| Memory cannot grant authority | public API audit, compile/runtime assertions, `INV-021` proof obligation | +| Lifecycle and deletion are replay-safe | transition table tests, tombstone dominance tests, rebuild equivalence fixtures | +| Retrieval is bounded, deterministic, and explainable | ranking permutation tests, score fixtures, budget/filter exclusion tests | +| Poisoned memory stays inert | repository/external/tool instruction-like payload corpus retaining quoted provenance | +| Crates are maintainable | architecture/source-layout/ordinary-API gates, docs, no forbidden placeholders | + +No criterion may be waived by returning an empty plan, ignoring a test, replacing a +production-path dependency with an in-memory test double, or relying on undocumented ordering. + +## Current architecture + +B1 already owns the stable `ActorRole`, nonconfigurable operation separation, capability scopes, +and authorization transitions. B2 owns immutable acceptance/review contracts and +`ReviewerIndependence`. B3 owns durable domain protocol and bounded codecs. C0 owns durable event, +artifact, and projection storage. C4 owns tool authorization. C5 owns provider-neutral request and +event protocols. + +C6 sits in the reserved `crates/orchestration` layer. The layer may depend on foundation, state, +runtime, tools, model, and orchestration, but this slice deliberately keeps its production +dependencies to A1/B1/B2 contracts. It does not need C5: render plans are neutral and D0 will map +them into `peritus-model-protocol::Message` values. It does not need C0: C6 defines canonical +records and replay/rebuild calculations while a future composition boundary persists events. + +The repository has no existing orchestration crate and therefore no compatibility migration is +required. The canonical architecture registry already assigns these exact crate names to C6. + +Reference implementations informed, but do not constrain, this design: + +- Codex CLI demonstrates separate context fragments, bounded compaction lifecycle, and child role + configuration that can reduce but not replace parent authority. +- LemonHarness demonstrates explicit workspace state, execution records, context budgets, memory, + and implementer/reviewer phases. +- NexAU-AHE demonstrates configurable compaction triggers/strategies and session memory, while C6 + replaces its string-oriented and in-memory behavior with typed provenance and verified plans. + +## Proposed design + +### Crate dependency graph + +```text +peritus-types ───────────────┐ + ├── peritus-role ───────┐ +peritus-policy ──────────────┤ ├── peritus-context +peritus-spec ────────────────┘ └── peritus-memory + +peritus-context and peritus-memory do not depend on each other. +D0 converts retrieved memory candidates into context nodes through public checked constructors. +``` + +`peritus-role` uses verification class `V`. `peritus-context` and `peritus-memory` use class `H` +because their ordinary-safe boundaries compute canonical SHA-256 content and index digests through +the existing H-class codec; their deterministic planning, validation, lifecycle, and ranking cores +remain Verus-verified and all three packages set `package.metadata.verus.verify = true`. Future I/O +or persistence adapters still belong in separate composition crates rather than these pure +contracts. + +### `peritus-role` + +Module layout: + +```text +src/ + lib.rs + capability_view.rs + context_policy.rs + context_class.rs + harness_role.rs + independence.rs + presentation.rs + verified.rs +tests/ + role_matrix.rs + reviewer_independence.rs +``` + +`HarnessRole` covers `Writer`, `Reviewer`, `Fixer`, `Evaluator`, and `Evolver` and has an exact +mapping to a B1 `ActorRole`. Restricted profiles for other B1 roles are produced through +`RoleProfile::for_actor_role`, so no role is implicitly privileged. + +`ContextClass` is a presentation/selection classification, not provenance. It includes immutable +policy, acceptance specification, active user request, repository instructions/source/diff, +workspace state, gate evidence, tool observation, memory evidence, prior findings/resolutions, +agent progress, and hidden reasoning. Context nodes retain the more fundamental provenance and +authority types owned by `peritus-context`. + +`ContextPolicy` uses canonical `ContextClassSet` values and explicit booleans/enums for fresh +context, memory use, producer ancestry, and presentation. `CapabilityView` is an ordered subset of +`OperationClass`; construction proves each operation is permitted by the underlying B1 role. +It never contains a `Capability` or `CapabilityScope`. + +`ReviewIndependenceView` copies the immutable required facts from B2 +`ReviewerIndependence` together with a required fresh-context flag. It is evidence requested from +D2, not a claim that independence has already been established. + +### `peritus-context` + +Module layout: + +```text +src/ + lib.rs + authority.rs + budget.rs + compaction.rs + compaction/range.rs + content.rs + error.rs + graph.rs + graph/validation.rs + identity.rs + node.rs + plan.rs + precedence.rs + provenance.rs + render.rs + selection.rs + selection/closure.rs + selection/ranking.rs + trust.rs + verified.rs +tests/ + compaction_matrix.rs + graph_matrix.rs + poisoning.rs + selection_matrix.rs + fixtures.rs +fixtures/v1/ + MANIFEST + SHA256SUMS + *.plan +``` + +Identity wrappers are fixed-size byte values so they are deterministic and cheap to verify: +`ContextNodeId([u8; 16])`, `CompactionPolicyId(Sha256Digest)`, and `ContextPlanId(Sha256Digest)`. +They own no random generator; callers inject identities. + +`Provenance` contains `System`, `Application`, `User`, `Repository`, `External`, `Memory`, `Tool`, +`Agent`, `Review`, and `DerivedCompaction`. `AuthorityClass` is ordered separately and contains +`SystemPolicy`, `ApplicationPolicy`, `AcceptanceSpecification`, `UserInstruction`, and +`NonAuthoritative`. A compatibility function rejects combinations such as external provenance +claiming application authority. `TrustClass` contains `Trusted`, `Constrained`, and `Untrusted`; +provenance establishes the maximum trust that a constructor may accept. + +`ContextNode` stores metadata and typed content bytes. Content is bounded by an explicit +`ContextLimits` policy. The digest is verified against content by the constructor; text is not +reparsed for authority. `RequirementMode` is `Required`, `DependencyRequired`, or `Optional`. +`ContextGraph::new` accepts nodes in canonical ID order and validates identity, edges, and DAG +shape. + +`TokenBudget` is constructed from context window, reserved output, and reserved overhead with +checked subtraction. `SelectionPolicy` carries role policy, allowed node/byte/token limits, and +optional ranking weights. The selector: + +1. filters nodes by the frozen role visibility contract; +2. forms complete dependency closures for required nodes; +3. rejects unsatisfied required closure or required budget overflow; +4. ranks optional roots with an integer tuple, never floating point; +5. admits an optional root only with its entire not-yet-selected closure; and +6. emits ordered selected entries and explicit omission records. + +`CompactionProposal` contains source ranges over selected nodes. `validate_compaction` produces a +`ValidatedCompaction` only after all protected-content, lineage, range, digest, visibility, and +budget checks pass. The function does not generate prose or claim summary fidelity; a provider may +propose content, but Peritus validates whether the derivation is admissible and retains the source +lineage. + +`RenderPlan` contains ordered `RenderSegment` values. Each segment contains its source identity, +context class, model-facing message role, provenance, authority, trust, digest, and bounded content. +No rendering method returns a capability or provider transport. Provider-specific conversion is a +D0 adapter with an exhaustive role map. + +### `peritus-memory` + +Module layout: + +```text +src/ + lib.rs + claim.rs + confidence.rs + error.rs + evidence.rs + feedback.rs + identity.rs + index.rs + lifecycle.rs + lifecycle/transition.rs + record.rs + retrieval.rs + retrieval/filter.rs + retrieval/ranking.rs + scope.rs + tombstone.rs + verified.rs +tests/ + index_rebuild.rs + lifecycle_matrix.rs + poisoning.rs + retrieval_matrix.rs + fixtures.rs +fixtures/v1/ + MANIFEST + SHA256SUMS + *.index +``` + +The crate uses caller-supplied `MemoryId([u8; 16])`, C0 `EventId`/`EvidenceId` foundation types, +and `Sha256Digest`. `Observation` is an explicit logical epoch/tick pair; no wall clock is read. +`MemoryScope` contains optional project/workspace/repository/actor/role dimensions plus a required +scope kind. At least one durable scope dimension is required, and query compatibility is exact or +explicitly broader according to `ScopePolicy`. + +`Confidence` and retrieval components are bounded integer basis points (`0..=10_000`) rather than +floating point. `EvidenceSet` stores canonical unique IDs. `ClaimType` distinguishes fact, +preference, procedure, outcome, warning, constraint, and hypothesis without conferring authority. +`RetrievalFeatures` are canonical key/digest/weight triples; they do not embed a provider-specific +vector index. + +`MemoryRecord` is immutable. Lifecycle methods return a revised record or tombstone and require a +monotonically increasing revision and observation. `MemoryState` contains `Active`, `Quarantined`, +`Expired`, and `Superseded`; `Forgotten` is represented only by a tombstone so deleted content is +not retained in the active model. + +`RetrievalPolicy` defines token/result limits, minimum confidence, accepted claim types, required +review freshness, ranking weights, and quarantine behavior. `RetrievalQuery` contains exact scope, +role profile, observation, query features, and a caller-supplied token budget. Filtering precedes +ranking. The result includes selected `MemoryCandidate` metadata and an `ExcludedMemory` for every +unselected input. Candidate materialization exposes provenance of the underlying source and an +explicit `quoted_evidence` flag. D0 copies this data into a checked context node. + +`MemoryIndex::rebuild` consumes canonically sorted records and tombstones, applies tombstone +dominance, excludes inactive records, and constructs deterministic scope/claim/feature posting +lists plus an index digest. The index is an optimization; retrieval against its canonical active +record view is defined to match a full scan. + +### Parallel implementation ownership + +After the role contract is committed in the working branch: + +- context track owns only `crates/orchestration/peritus-context/**`; +- memory track owns only `crates/orchestration/peritus-memory/**`; and +- integration owner retains root `Cargo.toml`, `Cargo.lock`, `architecture.toml`, verification + manifests, `peritus-role`, shared documentation, conformance wiring, and final fixtures. + +The two tracks may read but not edit one another's crate. They communicate through the frozen role +API and the field-level candidate contract in this design, avoiding shared-file collisions. + +### Credible alternative and rejection + +A credible alternative is a single `peritus-context-memory` crate with one graph containing live +context nodes, compacted nodes, and memory records. This reduces initial type conversion and might +make global token selection shorter. + +It is rejected because it couples ephemeral prompt assembly to durable retention policy, makes +forgetting/index rebuild affect the context selector, encourages one large stateful service, and +prevents independent ownership. It would also tempt memory entries to inherit authority directly +from context nodes. The separate-crate design preserves one-way immutable data flow and keeps +authority compatibility checks at both boundaries. + +## Data and compatibility + +C6 introduces no persisted wire format and therefore requires no C0 migration. Fixture encodings +are test-only canonical textual records with versioned manifests and SHA-256 inventories. Public +enum order is not treated as a wire tag unless explicitly documented. + +All identifiers and digests are caller-supplied fixed-width values. All ordered collections require +canonical ascending order and uniqueness. All numeric scores use bounded integers. These choices +make equality, replay, cross-platform behavior, and future B3 serialization deterministic. + +Future persistence shall use new B3 commands/events and C0 projections. Compatibility rules will +be additive: unknown enum tags fail closed, new optional metadata receives explicit defaults, and +tombstones remain valid across index schema generations. C6 types shall not derive a general +deserializer that bypasses checked constructors. + +## Failure handling + +Each crate defines a stable error kind and structured error carrying the affected collection, +field, and identifier where appropriate. Expected failures include invalid bounds, canonical-order +violations, incompatible authority/trust, missing graph dependencies, cycles, hidden required +content, budget exhaustion, protected compaction sources, illegal lifecycle transitions, stale +observations/revisions, scope mismatch, and tombstone conflicts. + +Planning is transactional in memory: constructors and planners return either a complete valid +value or an error and do not mutate inputs. Retrieval returns a complete explanation including +normal exclusions; malformed canonical state remains an error. Arithmetic uses checked operations +and reports overflow rather than wrapping. + +There are no retries, clocks, network operations, file operations, or process operations in these +crates. D0/C0 callers decide persistence and retry policy based on typed failures. + +## Security considerations + +The principal security property is provenance separation, not content inspection. Instruction-like +text from repositories, external pages, tools, agents, reviews, or memory remains typed data at its +original authority/trust ceiling. Rendering retains boundaries and never changes that ceiling. + +Role projections can only narrow B1 permissions. `peritus-role` has no capability issuance API, +and context/memory contain no capability type. Reviewer profiles exclude mutation and producer +hidden reasoning. Memory cannot amend policy/specification, accept work, waive findings, grant +tools, or rewrite harness components. + +Bounds limit graph size, dependency fan-out, content bytes, token estimates, evidence counts, +retrieval features, selected results, and score arithmetic. This prevents unbounded allocations at +the control boundary without inventing speculative adversaries. Poisoning tests focus on likely +inputs: repository instructions, copied web text, tool output, model summaries, and stale memories. + +Digests provide identity and replay binding, not proof that prose is true. Confidence and evidence +are explicit inputs, not automatic trust escalation. Compaction validation proves lineage and +policy compliance but does not prove semantic faithfulness; reviewers and later evaluation remain +responsible for that evidence. + +## Verification + +### Verus obligations + +The slice registers semantic obligations covering: + +- `INV-021 MemoryNonAuthority`; +- role capability views are subsets of B1 `permits_operation`; +- selected nodes are visible and their dependency closure is complete; +- selected and reserved token totals never exceed the declared context window; +- required-node failures cannot produce a plan; +- compaction sources remain linked and protected classes are never compacted; +- memory lifecycle revisions/observations advance monotonically; +- forgotten/tombstoned records are absent after rebuild; and +- retrieval results satisfy lifecycle, scope, role, confidence, expiry, and budget filters. + +Every executable pure validator exposes postconditions used by focused proof roots. No proof root +may assume the property it claims or use `external_body`, `admit`, `assume`, `axiom`, or an approved +TCB exception. + +### Test matrix + +Tests cover ordinary constructor and accessor behavior, exhaustive role matrices, graph cycles and +dependency closure, token boundaries and overflow, deterministic selection across permutations, +compaction rejection reasons, render ordering, memory lifecycle transitions, evidence conflicts, +scope filtering, ranking ties, expiry/quarantine/tombstone dominance, index rebuild equivalence, +and poisoned instruction-like content from every non-authoritative provenance. + +Focused commands use system-memory-aware parallelism: + +```text +cargo fmt --all -- --check +CARGO_BUILD_JOBS=2 cargo test -p peritus-role -p peritus-context -p peritus-memory \ + --all-targets --all-features --locked +CARGO_BUILD_JOBS=2 cargo clippy -p peritus-role -p peritus-context -p peritus-memory \ + --all-targets --all-features --locked -- -D warnings +CARGO_BUILD_JOBS=2 RUSTDOCFLAGS='-D warnings' cargo doc \ + -p peritus-role -p peritus-context -p peritus-memory --all-features --no-deps --locked +just source-layout +just architecture +just ordinary-api +CARGO_BUILD_JOBS=1 cargo verus verify --package peritus-role --package peritus-context \ + --package peritus-memory --all-features --locked --check-toolchain \ + --fwd-verus-args-to roots -- --no-cheating --rlimit 20 +CARGO_BUILD_JOBS=1 cargo verus build --package peritus-role --package peritus-context \ + --package peritus-memory --all-features --release --locked --check-toolchain \ + --fwd-verus-args-to roots -- --no-cheating --rlimit 20 +``` + +Before merge, full Gate A and Foundation matrices must pass locally where applicable and on hosted +Ubuntu, macOS, and Windows runners.

No data rollback or compatibility shim is required. Once D0 persists C6 +records, later changes must follow B3/C0 migration policy; that is outside this slice. + +Operationally these crates allocate only bounded in-process data and perform no I/O. D0 will record +plan/retrieval digests and typed failures in the journal and C7 trace. Performance baselines for +graph selection, retrieval, and rebuild are recorded now; production SLO qualification remains H3 +without weakening correctness. + +## Open questions + +There are no implementation-blocking open questions. + +Future slices must decide: + +- the B3 wire tags for persisted context/memory commands and events; +- which C5 tokenizer estimator supplies provider-specific estimates to D0; +- the storage/index backend used by C0 projections at production scale; +- the exact model/provider diversity rule used by D2 review quorum; and +- user-facing retention defaults and CLI wording in G1. + +Those decisions do not change C6's pure contracts: callers inject estimates, observations, +features, policies, and durable identifiers. + +## Out of scope + +The following belong to later canonical slices and are not smuggled into C6: + +- model invocation, streaming, tokenizer network calls, and provider-specific message encoding + (C5/D0); +- durable command/event encoding and persistence (B3/C0/D0); +- tool execution or capability issuance/consumption (B1/C4/D0); +- the edit/run/test turn state machine and pause/cancel recovery (D0); +- gate DAG execution and freshness evaluation (D1); +- finding lifecycle, review quorum adjudication, and waiver/acceptance (D2); +- scheduling, collaboration, tracing, telemetry, debugger reports, evaluation campaigns, harness + mutation, daemon/CLI/TUI, and final performance/release qualification (D3 onward). + +These are dependency boundaries, not descoping of the production project. C6 implements its full +production contract and leaves later slices to consume it without placeholder behavior. diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index

It is implemented in three orchestration-layer crates: + +- `peritus-role` projects canonical B1 roles into context and presentation policy; +- `peritus-context` validates provenance graphs and produces bounded context/render plans; and +- `peritus-memory` validates derived-memory records and produces bounded retrieval/index plans. + +The crates perform no I/O and hold no ambient authority. D0 will persist their inputs and outputs +through C0/B3, map render segments into C5 model requests, and mediate tools through C4. + +## Authority boundary + +`peritus-policy::ActorRole` remains the only security-role identity. C6 does not issue or consume +capabilities, change policy, accept work, waive findings, amend an acceptance specification, or +promote a harness. + +`peritus-role` defines the writer, reviewer, fixer, evaluator, and evolution-agent context profiles +and restricted profiles for every other B1 role. Its capability view is only a read-only ordered +set of operation classes. Construction rejects any operation B1 does not permit, and the verified +subset predicate connects the executable result to B1's formal permission specification. + +Reviewer context is always fresh and excludes producer ancestry, producer-hidden reasoning, and +memory-derived producer rationale. It contains the immutable specification, exact candidate, +relevant source, gate evidence, and prior finding/resolution evidence needed for an independent +read-only review. `ReviewIndependenceView` copies every B2 contract requirement and adds the C6 +fresh-context requirement; it requests evidence rather than claiming that independence exists. + +## Provenance-aware context + +Context is a directed acyclic graph of bounded nodes, not a concatenated prompt. A node binds its +identity and content digest to: + +- provenance such as system, application, user, repository, external, memory, tool, agent, review, + or derived compaction; +- an independently checked authority and trust ceiling; +- a semantic context class used by role policy; +- required/optional selection mode, explicit priority, token estimate, and recency; +- exact role visibility; and +- a canonical dependency list. + +Constructors reject inconsistent provenance/authority/trust combinations, empty or oversized +content, zero estimates, self-dependencies, duplicates, and noncanonical collections. Graph +construction rejects duplicate identities, missing dependencies, and cycles before selection. + +Repository instructions, fetched text, tool results, model output, reviews, and memory can contain +instruction-like prose, but parsing prose never raises its authority. The metadata supplied by a +checked constructor determines its ceiling, and rendering keeps every source boundary explicit. + +## Selection and token planning + +The context selector operates deterministically: + +1. apply the selected role's visibility policy; +2. calculate the complete dependency closure for required nodes; +3. fail with a typed error if any required node is hidden, incomplete, or over budget; +4. rank optional roots by the documented integer precedence tuple; +5. admit an optional root only when its entire not-yet-selected dependency closure fits; and +6. retain an explanation for every selected or omitted node. + +The token budget records context-window capacity, reserved model output, reserved protocol +overhead, usable input, selected input, and remaining input. All arithmetic is checked. A plan is +returned only when required closure and accounting are complete; there is no partial-success path +that silently drops policy or specification material. + +The planner accepts caller-supplied token estimates. D0 will obtain estimates from the selected C5 +provider/tokenizer profile, but C6 remains deterministic and provider-neutral. + +## Compaction and rendering + +Compaction is an explicit derivation. A proposal identifies a new node, a compaction-policy digest, +the proposed bounded content, and canonical nonempty ranges from selected source nodes. Validation +rejects missing or hidden sources, invalid or overlapping ranges, digest/lineage errors, cycles, +and proposals that do not reduce the replaced token estimate. + +Immutable policy, acceptance specifications, active user instructions, capability facts, and +unresolved blocking findings are protected from summarization. A successful derivation retains +links to every source and never raises the maximum authority or trust of its inputs. Validation +proves admissible lineage and bounds; it does not pretend that a prose summary is automatically +true. + +A render plan is an ordered list of typed segments carrying source identity, message role, +provenance, authority, trust, context class, digest, and bounded content. Provider-specific message +encoding is deliberately deferred to D0's adapter into `peritus-model-protocol`. + +## Derived memory + +Memory records are immutable derived claims. Each record binds: + +- a stable caller-supplied identifier and revision; +- exact project/workspace/repository/actor/role scope; +- canonical source events and supporting/contradicting evidence; +- claim type and original source provenance; +- bounded confidence, relevance features, token estimate, and feedback; +- explicit logical creation/review/expiry observations; and +- active, quarantined, expired, or superseded lifecycle state. + +Logical observations are supplied by the durable caller; the crate never reads the wall clock. +Confidence and ranking use bounded integer scores rather than platform-sensitive floating point. +Constructors reject empty scope/source data, evidence conflicts, noncanonical features, stale +observations, invalid expiry, zero revisions, and out-of-range scores. + +Lifecycle operations return a new checked revision. Quarantine release requires a later review; +expiry and supersession are explicit. Forgetting does not retain content in an inactive record: it +produces a tombstone binding the memory identity, prior digest/revision, deletion observation, and +reason. During replay or rebuild, a tombstone dominates records at or below its revision. + +## Retrieval and rebuildable indexes + +Retrieval filters before ranking. Scope compatibility, role visibility, lifecycle, quarantine, +expiry, minimum confidence, claim type, required features, and tombstones are all checked before a +candidate can receive a score. + +Ranking uses bounded integer components for scope specificity, relevance, confidence, evidence +balance, recency, and feedback. Stable identity order breaks ties. Result and token limits are +checked during admission. The retrieval plan includes an explanation for every input record: +selected with component scores, or excluded with a typed reason. + +Selected memories materialize as quoted, non-authoritative evidence carrying the original source +provenance. D0 may turn that metadata into a checked context node; it cannot turn it into policy or +a capability. + +The memory index is a rebuildable projection over canonical records and tombstones. Rebuilding the +same ordered inputs produces the same active record set, posting lists, and digest. Correctness is +defined by the canonical active-record view rather than by an index backend, allowing future C0 +storage changes without changing retrieval semantics. + +## Verification and maintenance + +`peritus-role` uses verification class `V`; `peritus-context` and `peritus-memory` use class `H` +because their ordinary-safe boundaries compute canonical SHA-256 content and index digests through +the existing H-class codec. Deterministic constructors, graph validation, token accounting, +selection, compaction admission, lifecycle transitions, tombstone dominance, scoring, retrieval, +and rebuild calculations remain ordinary safe Rust inside Verus boundaries. There are no trusted +constructs, exclusions, unsafe blocks, effect handles, provider calls, or placeholder success +paths. + +Focused development checks are: + +```text +CARGO_BUILD_JOBS=2 cargo test -p peritus-role -p peritus-context -p peritus-memory \ + --all-targets --all-features --locked +CARGO_BUILD_JOBS=2 cargo clippy -p peritus-role -p peritus-context -p peritus-memory \ + --all-targets --all-features --locked -- -D warnings +CARGO_BUILD_JOBS=2 RUSTDOCFLAGS='-D warnings' cargo doc \ + -p peritus-role -p peritus-context -p peritus-memory --all-features --no-deps --locked +CARGO_BUILD_JOBS=1 cargo verus verify \ + --package peritus-role --package peritus-context --package peritus-memory \ + --all-features --locked --check-toolchain --fwd-verus-args-to roots \ + -- --no-cheating --rlimit 20 +``` + +The complete merge authority remains `just gate-a` plus required hosted Ubuntu, macOS, and Windows +checks.

Once C6 is merged, D0 can build the durable model/tool loop by combining +B0 lifecycle transitions, B1 authority, B3/C0 durability, C4 tools, C5 providers, and C6 plans. +Review finding lifecycle and quorum adjudication remain D2; context merely supplies the fresh, +bounded evidence view they require. diff --git a/justfile b/justfile index 9e27e327b..38e633c97 100644 --- a/justfile +++ b/justfile
