feat(edict): execute authenticated source functions in pure and read operations - #753
Conversation
Implement fresh lexical frames, ordered argument evaluation, shared metering and independent complete-closure provider admission. Select the source-function contract publication explicitly while preserving legacy publications. Native behavior and package assets are verified; independent component reproduction and the public compiler/runtime witness remain required before merge.

Confirmed and repaired the duplicate import-inventory findings: both providers now audit imported helper bodies before any no-source-function early return. Present inventories retain the existing imported subset; absent empty inventories preserve prior provider compatibility. A component-backed helper without source declarations fails the new regression on the old implementation. Docker full provider suites passed after the fix; exact formatted checks are running. Nominal identity and publication-witness findings remain pending and threads will stay open until published fixes are verified. The current branch also contains ordinary merge fb1fde7 of current main 2d79ecc. No rebase or history rewrite. @codex |

Nominal identity repaired and published in 382bc73. Both independent bounded-read type judgments retain the resolved nominal contract key and representation; distinct nominal and nominal-versus-bare assignments, arguments and outputs refuse. Same-identity comparisons inspect representation only after identity equality, and basis/address shape checks remain explicit physical role checks. Docker RED demonstrated that A and B with the same U64 representation incorrectly converted without a source-function table. Full provider suites passed after the fix; final exact-source library regressions, formatting and strict all-target provider Clippy passed. Canonical host documentation updated. Imported-helper repair is 024e844. Runtime publication/component evidence and remaining witness findings are still pending; no merge readiness claimed. |

Publication-witness findings repaired and published:
All four deterministic Python witness tests pass in Docker. Final reports use exact projected replacement size, a bounded stable self-accounting calculation, and an actual-tree verification; oversized report replacement refuses before writing. These mocked compiler cases verify witness logic, not public compiler/runtime compatibility. Real component/publication gates remain pending. |

Addressed the helper-frame allocation nit in 91c5fba: pure and bounded-read evaluation scopes borrow identifiers from the immutable decoded Program instead of cloning String keys. Deterministic BTreeMap ordering and Value metering remain unchanged. Before/after source evidence shows removed input/binding/parameter ID clones; no timing or RSS improvement is claimed. Docker source-function and node-read runtime suites plus formatting passed. Component/publication validation remains pending. |

Rebuilt component publication is published in 0bcc95b. Two separate successful designated x86 CI build jobs checked out exact source 91c5fba and emitted byte-identical pairs: job 1, job 2. The comparison job's RED was the expected old-approved-digest mismatch. Both candidate pairs were downloaded, compared exactly and passed the portable promotion command's interface, identity and distinct-input gates in Docker.
All checked/package/carrier copies, manifest component bindings, configured promotion identities and current README figures are updated. Docker exact asset/resource checks, 17 package/publication/contract-pack tests and formatting passed. Actual public compiler/runtime crossing and final current-head review remain separate gates. A local ARM checked-build attempt refused its host before compilation; an x86 copy-setup attempt failed before building. Neither is counted as component RED/GREEN evidence. Those owned failed input copies were verified against the source manifest and reclaimed. Agy's current-head review service is quota-blocked. No merge approval or production adoption is inferred from these checks. |

The full independent exact-head adversarial approval is posted above. All eight inline threads are resolved; inherited same-prefix named-type lookup limitations remain documented. Frozen host compatibility: 51 passed, three existing ignored. These are private computation/read witnesses, not causal settlement or installation. Current hosted CI and a final live review/head check remain required before the already-authorized merge. |

Merged into main as
a8529d62after current-head independent review and hosted gates.Edict now emits source-owned pure functions, but Echo's existing execution path only handles the narrower imported-helper form. This change adds generic source-function admission and execution to both pure and bounded-read operations, allowing authored helpers to consume ordinary inputs or retained atom bytes.
Closes #752. The compiler prerequisite, Edict #226, landed through PR #228 at
01161c1745baad0d713234ba1a671b9a26923aa4.Behavior and authority
Core.functions, separate from imported lawpack facts. The lowerer and independently implemented verifier check signatures, lexical frames, the complete call graph including unused definitions, Core/Target agreement, totality, depth and costs.SourceFunctionscontract selection imports the complete Edict publication. Existing schema publications and the default pure-binding selector remain intact. Regenerated provider provenance and package identities may change with source identity.The supported target subset remains bounded unsigned words, bytes and records, including nominal types over supported representations. Combined runtime depth is 64; the compiler's 128-frame source limit is a different contract. Boolean/string/list and effectful helpers are outside this provider subset. This adds no Jim-specific dispatch, editing logic, native Buffer decoder or rope implementation.
The standalone provider-host suite retains its frozen
2e3f52f9compiler/host, exact fixture identities and broader refusal/replay contracts. The separately pinned current Edict CLI witness invokes both components through its actual host, then supplies the exact emitted package/report bytes to the runtime checks. Both crossings remain required against the final provider components.Current remediation evidence
The final Int-aware components were reproduced by two separate designated CI builders at source

def8543ce57840b2f8a60e5729a80dc74d195a0ccompiled all eight public witness variants through the selected provider. Successful package/report pairs repeat byte-for-byte; the old provider refuses source functions, and both old/new providers retain function-free compatibility. The runtime consumer at187c6663executes the unchanged pure, renamed and changed-body packages across 12 literal cases each, plus one immutable stored Atom read (five bytes). Completed compiler evidence SHA-256:afee6e6192ff162dd060bb52bb0d7f308ecd204c58763620e4235ffca904a3c2. Independently selected evidence and case hashes bind the exact byte vectors used by execution. A substituted-cases RED/GREEN witness proves refusal after the provenance repair.The frozen
2e3f52f9host suite against the final components passes 51 tests, with three existing ignored tests. These compiler/runtime and compatibility checks ran in the guarded Docker worker. They establish private computation and bounded reading, not installation, causal settlement or crash durability. Earlier evidence remains historical and is not relabeled as a current run.The late runtime named-Int parity finding is repaired at
b8a7c4fe: a called helper with named integer parameter/result fails withUnsupportedProgrambefore the fix and passes afterward. The shared parser resolvesIntthrough its declared width. Docker checks pass 14 source-function, seven retained pure and fourteen read tests, strict Clippy, formatting and the unchanged public runtime witness. The regression has test-owned pins and is not additional compiler provenance. Final review and hosted CI are refreshed for this candidate.Agy's quota is exhausted. The user explicitly authorized an independent Codex reviewer with the same adversarial checklist. Final exact-head review and hosted CI passed before merge.
Verification and remaining merge gates
The native regression suite covers ordered/once-only arguments and budget refusals, fresh frames, unused malformed functions, recursion and depth, diamond occurrence costs, input identity, optional pure basis, nominal compatibility, exact call authority, coherent artifact tampering, and real stored atom reads. Synthetic carrier tests are explicitly identified as such; they are not public compiler provenance.
Independent review exposed three native defects, each with observed failing tests before remediation: imported-effect/source-function collisions, same-package imported call ownership, and nominal identity erasure. Their individual validation and commits are recorded in the review follow-up. The final native remediation gate at
20e380e1passes 86 tests across six provider/runtime summaries, formatting, and strict provider Clippy; an independent reviewer bound all 981 source files to that committed candidate. This is focused native approval, with the publication gates below still outstanding.The designated component builders, public crossings, compatibility checks and final reviews are complete. The final merge gates were:
bc516761, source4d8dc13e, CI run 37733255394).The current same-prefix type lookup limitation remains explicit: named types resolve through module-relative
Core.typeskeys, so fully qualified imported keys under that same prefix can still refuse. The call-ownership regression isolates its own behavior and does not claim to repair that inherited compatibility gap.Documentation and scope
Current behavior and limits live in application contract hosting, provider publication, and the generator instructions. The changelog and feature-enabled test routes are updated. This closes generic helper execution only; Jim's decoder, persistent rope, and broader delivery work remain outside this PR.
