Dependency-ordered future kernel, bridge, extraction and Intent implementation work.

Core-3 Dependency-Ordered Implementation Roadmap

Status: planned follow-ups; no implementation or tracking-system mutation is implied by this document. The specification can be delivered and reviewed before any of these implementation projects starts.

Order Work Depends on Completion evidence
1 Foundation audit and proof-term/parser/elaborator inspection Specification acceptance Closed typed terms, adversarial universe/positivity cases, explicit metatheoretic assumptions; no runtime claims
2 Small independent-checkable kernel and minimal logical library 1 Checked propositions, inductives/recursors, exact challenge matching, derived axiom footprints, bounded failures
3 Logical proof/environment transport and identity validation 1, 2 Canonical vectors, reference closure, tamper rejection, independent rechecking and version isolation
4 Algorithm semantic bridge 2, 3 Checked operational model, partial/total distinction, numeric/ownership/error behavior, disclosed encoder trust
5 Compute, State, Flow, Optimize, Hardware, Physics bridges 4 and each actual backend/model Per-paradigm obligations from verification; physical fidelity and bounded evidence remain distinct
6 Computational extraction 2, 3, 4 Erasure and representation preservation; noncomputability rejection; host resource/error behavior
7 Intent declarations, policy/authority and formalization records 1, 3 Complete coverage, authenticated delegated approval, pinned challenges, protected context and independent-approval cases
8 Code/plan resolution, validation and admission 4, 7 Both product kinds satisfy one approved contract; no weakened-evidence fallback; pre/postcheck distinction
9 Capability-gated Intent runtime and provider boundary 8 Bounded resource reservations, cancellation/failure, scoped provider/context/execution grants, no implicit compiler model access
10 Durable Intent activities, replay and recovery 9 and Flow/action journal No model rerun on replay, immutable revisions, crash-gap and indeterminate-effect recovery
11 Canonical runtime snapshot and Proof/Intent ZDE views Paired with 9 and 10 Typed snapshot and user-visible ownership/evidence/budget/uncertainty tests, no UI-only state store
12 Physical ZLM4 transport, independent checker agreement and broader release evidence 3, 6, 10, 11 Frozen encoding, property/mutation tests, compatibility, provenance and activation review

Each implementation step follows test-first ordering with public-interface assertions. Property tests cover serialization, canonical identities, alpha-renaming, exact dependency reuse, and replay invariants. Behavior-bearing mutants must be killed with new tests; equivalent mutants are documented.

Large theorem libraries, automatic Lean import, a tactics language, mutually recursive/nested inductives, higher-order extraction, implicit runtime model calls, and general natural-language equivalence are not promises of this preview. A future expansion needs explicit semantics and separately identified conformance, not permissive unknown-record handling.
