Compile pure source functions into authenticated Core - #228
Conversation
Implementation checkpoint for #226. Observed guarded RED covered declaration parsing, Boolean composition, byte comparison budgets, and require-only semantic closure. Final closure GREEN, generated contract publication, public application compatibility, documentation, formatting and full gate remain pending. No downstream runtime support is claimed.
Preserve the frozen function-free publication and add the explicitly selected source-function contract pack. Keep executable source authority disjoint from imported facts, make cost caches independent of diagnostic spans, and account for synthetic Boolean operands. Add adversarial source/Core/Target cases, documented compiler and consumer boundaries, and a guarded public Jim old-provider witness. Evidence: prior exact 23bc539 focused 27 syntax plus 1 CLI checks and the broader 699-test syntax suite passed. Subsequent span, Boolean-allocation and unused-effect authority REDs were observed; span/yield regressions passed in later focused runs. Docker formatting and contract generation completed. Corrected Boolean/effect tests, the supplemental unused-pure-fact case, full cargo xtask verify, and the public old-provider harness remain pending at this candidate. No Echo runtime acceptance is claimed.
…prefixes Compare imported effects by canonical export coordinate, not source alias. Classify source-call graph edges by exact table membership, preserving independently authenticated imports with disjoint names in the same package. Retain missing-fact, unknown-export, recursion and arity refusals. Resolve strict Clippy diagnostics with explicit imports, typed map initialization and cohesive compiler helper extraction. Guarded focused validation passed all 63 lawpack and 31 source-function tests with all 466 source hashes unchanged. The package-prefix regression first reproduced InvalidDefinition after its separate-package control passed. Prior 6eb11ab public Jim controls produced a verified function-free package and explicitly refused source functions under the pinned old provider; no runtime source-function acceptance is claimed. Docker formatting completed. The final exact-head cargo xtask verify and public witness remain pending.
Use std::fmt::Write for the call-chain, repeated-diamond and branch-yield fixture builders. Preserve fixture bytes, order, newlines, assertions and budgets. This mechanical cleanup addresses the three test-only strict Clippy failures from the exact 7d29b9a gate; Docker formatting completed. Final full verification and public compatibility witness remain pending.

| Severity | Finding | Correction/evidence | State |
|---|---|---|---|
| P1 | Diagnostic-span collisions could change static budget acceptance. | Immutable borrowed AST identity keys and original branch-yield traversal; real span-mutation RED followed by the committed regression passing. | Fixed in 6eb11ab, current full gate passes. |
| P1 | Boolean predicate lowering omitted synthetic constant storage. | Charge the generated true value; the sixteen-operand allocation regression has an actual pre-fix RED and current GREEN. | Fixed in 6eb11ab. |
| P1 | An unused source function could claim an imported effect coordinate; the first correction compared an alias. | Compare canonical imported coordinates; authenticated old-program positive control and unused effect/pure collision negatives pass. | Canonical correction in 7d29b9a. |
| P2 | Package-prefix classification rejected disjoint imported helpers in the source package. | Source graph membership comes from declared Core functions; exact imported authority remains required. Real separate-package control/shared-package RED, followed by both positives and missing/unknown-authority negatives. | Fixed in 7d29b9a. |
| P3 | Strict Clippy rejected production and fixture constructs. | Explicit imports/small helpers and direct string writes; no lint suppression or hook bypass. | Fixed in 7d29b9a and 83b9324; strict Clippy passes. |
| P4 | External Python evidence was listed as a Rust test, one oracle exceeded its assertions, and two IDs collided with merged cases. | Separate external witness documentation, precise projection oracle, unique new CSPINE-TP-054/TIR-TP-083. Existing cases and checker preserved. | Fixed in b4dac6b, d92bd7a, fc38cad, acd71fc; focused contract check and full gate pass. |
Setup failures are retained separately and are not counted as behavioral REDs. The initial source-function parser/compiler tests preceded the implementation. The public imported-pure collision control supplements coverage without an invented pre-fix RED.

Compiler acceptance is not Echo source-function execution. Combined source/imported depth, backend metering/type admission, public upgraded-provider packages and runtime witnesses belong to Echo #752; complete Jim decoder/rope behavior remains outside this PR. The source-only expression counter is not a global compiler resource cap, and portable allocation units are not physical allocator measurements.
The independently assigned Codex reviewer is reconciling the final source-bound receipts and current PR state. Hosted Codex automatic review reports a credit limit; it provides no approval. CodeRabbit is actively reviewing, so its approval and the required current-head CI remain merge gates.
Code Lawyer finding: stable-toolchain test diagnostics
@codex — this concrete CI finding is being corrected. The hosted credit-limit response is not an approving review; the independent local Codex review remains separately recorded and will receive the narrow delta. |

Independent adversarial review: Edict PR #228 stable-toolchain follow-upAPPROVE for the reviewed compiler/contract change at
Narrow follow-up and prior review continuityThis report preserves and extends the completed 54-file independent review at Four assertions in Hosted Rust 1.99 produced a real lint failure for the original four sites, then exposed the CLI stderr site after the first correction. I inspected both hosted failure logs, including the completed-job log obtained directly when the workflow as a whole was still running. These are strict-Clippy compatibility failures, not newly invented behavior REDs. The existing custom-message empty-node assertion was not flagged. The final corrections have exact-head pinned Rust 1.96 full/public GREEN; hosted stable acceptance is not inferred from that local result. The current-head source delta is substantively approved. The concrete stable-CI finding remains subject to its stated hosted GREEN acceptance before the merge owner can close that gate. Production-path reviewThe authored Signatures are collected before bodies. Each function gets a separate lexical environment and deterministic positional parameter/local identities. Duplicate declarations, invalid shadowing, captures, forward locals, incompatible argument/results and invalid unused definitions refuse. The accepted body is pure immutable bindings followed by a terminal return; effects, requests/reads, assertions, loops and unsupported statements do not silently disappear. Target validates every function body, including unused bodies, and checks partial-operation totality without borrowing caller input proofs. Calls retain ordered argument occurrences and their conditional, predicate and pre-body placement. The source-owned function table is distinct from validated lawpack facts. Every imported call still needs its exact authenticated signature/type/cost authority. Declaration-wide collision checks use canonical imported coordinates. Source-call graph edges are determined by exact declared membership, so a disjoint imported export can share a package coordinate without becoming an invented source definition. Missing facts and unknown exports still fail independent Target admission. The source graph uses active-path cycle detection and completed suffix heights. A leaf has height one; every caller includes its child's completed height, including reused suffixes. The 128/129 boundary and shared-suffix controls prevent traversal-order-dependent acceptance. Validated graph membership precedes indexed lookups, and bounded height arithmetic cannot overflow. Repeated call occurrences remain distinct for checked transitive cost composition even when graph edges are deduplicated for height analysis. Cost memoization uses original, immutably borrowed AST expression identity rather than diagnostic spans. Branch-yield traversal no longer clones statements and loses their identity. Callee syntax, predicate-only nodes, folded negative-literal children and an existing intent yield wrapper are not additional typed-value expressions. Boolean predicate reification now includes the synthetic Nonempty source-function tables force Target semantic closure to bind the complete Core digest, including unused functions and require-only programs. Parameter/local alpha-renaming preserves canonical identity; changed executable bodies change it. Empty tables are omitted, preserving function-free bytes. The new public Rust struct field requires Rust struct-literal callers to supply it; wire compatibility is not a promise of unchanged Rust construction syntax. Findings resolved during review
The previously considered huge-string overflow lead is withdrawn for function-bearing modules: checked operand storage bounds reject the proposed huge operands before concatenation reaches that addition. It is not listed as an unresolved finding. The source expression-occurrence limit is a narrower bound, not an advertised global parser/validator resource theorem. Inspected RED/GREEN and full-gate evidenceEvidence names below refer to retained raw logs/manifests/exports, not additional repository files. The reviewer inspected the execution scripts, raw streams, source bindings and terminal receipts rather than relying only on a summary.
Final evidence identities:
The final harness reads the preserved phase-manifest bytes directly; its hash equals the independently verified host input manifest. This final binding does not rely on the earlier Public old-provider boundaryThe final public harness uses the Jim application/vendor input at
The function-free package hash is The harness is executable repository code with documented parameters but needs caller-supplied Jim/provider inputs and the shared Docker guard. It is separate from Contract and compatibility checks
The new schema permits an optional nonempty source-function table with typed parameters, return type and pure body. The final schema test accepts function-free modules under both versions, accepts function-bearing modules only with explicit new-schema selection, and rejects incomplete signatures and explicit empty tables. The five contract resources, eleven contract roots and seven domain roots are unchanged; embedded resource digests match. The owner generator checks the new publication without rewriting the frozen pair. Existing canonical goldens pass. No provider or application pin was silently migrated. All added/changed topic rows were reviewed against their requirements, named test bodies, fixture paths and links. The final CLI wording distinguishes emitted table/digest observations from the compiler suite's argument-order proofs and from the external provider witness. Source-depth documentation explicitly says source-function paths, not a combined source-plus-imported limit. Resources and execution boundariesThe coordinating executor reused the established I inspected the final launch/result and admission/release receipts: Rust 1.96, incremental compilation disabled, 4 CPUs, 6 GiB memory, a 1,200-second deadline, bounded container logging and the existing fail-closed monitor over writable-layer/temp/shared-memory/cache/evidence/log storage. Final run measurements were 13,196,708,253 B build, 4,233,939,357 B data, 12,322,089 B logs, below the respective 20 GiB / 4 GiB / 128 MiB limits. Recorded host/VM free space was 711,105,449,984 B / 676,201,271,296 B, above the 50 GiB floor. The recorded data headroom was only 61,027,939 B, so subsequent heavy work still requires the ordinary fresh accounting/admission and owned-output cleanup policy. This report does not claim those measurements remain current indefinitely. The repository's Remaining limitations and merge conditions

@crates/edict-provider-schema/tests/provider_contract_pack.rs:
- Around line 1205-1212: Update the PROVIDERS-TP-049 test around
`assemble_provider_contract_pack` to assert that the reassembled legacy pack’s
raw SHA-256 matches the published v1 CDDL bytes, rather than only asserting that
its hash differs from the current pack. This binds the frozen legacy fixture to
the published v1 artifact.
Review comments at @crates/edict-syntax/src/compiler.rs:
- Around line 3535-3552: In the predicate-checking arm, passing the Bool
expectation to every expression lets calls and conditionals emit TypeMismatch
before the predicate check. Pass the expectation to check_expr_with_expected
only for Expr::If, and let the existing compatible check consistently emit
ExpectedPredicate for non-Bool operands.
Review comments at @crates/edict-syntax/src/compiler/source_functions.rs:
- Line 127: Update the statement-level rejection paths in the function handling
logic, including the “statement after function return” and “statement in a pure
function” cases, to report the offending Stmt’s span rather than
definition.span. Add a small stmt_span helper or extract the span from each Stmt
variant, and use it for both diagnostics.
- Around line 84-90: Update the failure-to-span lookup in the source-function
validation flow: the raw failure path is not always a function identifier, and
the work-budget sentinel must not match a function named work. Have
validate_function_graph provide the relevant function name, or extract the
leading function-name segment while explicitly excluding the work sentinel, then
use that name to find the definition span.
- Line 496: Update the source-function bound checks that call value_bound to
distinguish shapes containing ExternalActionRequest from genuine arithmetic
overflow. Report UnsupportedSourceShape for request-containing input, output, or
expression shapes, including nested occurrences; retain InvalidBound for actual
overflows.
Review comments at @docs/REQUIREMENTS.md:
- Line 86: Update the EDICT-ABI-PROVIDER-CONTRACT-PACK-001 row to describe the
current generator-owned publication and state that the prior v1 publication is
retained as exact frozen bytes; cite both the current fixture and the executable
check that proves v1 remains unchanged, using the relevant symbols in
provider_contract_pack.rs.
Review comments at @docs/topics/target-ir/test-plan.md:
- Line 261: Update TIR-REQ-022 and TIR-REQ-025 to require lawpack facts and
pure-helper authority only for imported helper calls, keeping their requirements
consistent with TIR-REQ-054’s treatment of source calls.
Review comments at @scripts/consumer-witnesses/jedit-source-functions.py:
- Around line 72-77: After `child.communicate` returns normally, call
`stop_group(child)` before assigning `result = child` so any surviving
descendants are terminated before output files are hashed; preserve the existing

Learning: When reviewing Edict result projection CDDL fixtures (e.g., provider-contracts/*/edict-provider-contracts.cddl generated from docs/abi/edict-result-projection.cddl), ensure the CDDL enforces only the CDDL-expressible *local* bounds: `maxOutputBytes` must be positive, records must have at most 255 fields, source-paths must have at most 32 segments, and text length limits must be present. Do not rely on (or duplicate) global limits for recursive expression nodes and total canonical-artifact bytes in CDDL; those *global* limits are intentionally enforced during authoritative decode/verification by `crates/edict-syntax/src/result_projection.rs`, which is invoked by `crates/edict-cli/src/application_build.rs` before provider binding.

Recurse through nominal, list, and record shapes, including zero-length lists. Retain InvalidBound for checked arithmetic overflow and preserve existing function-free request acceptance. Regression: request_value_shapes_are_unsupported_in_source_accounting_not_overflow (test-first in 36e3fb9) covers unused signatures, request-bearing values, valid function-free controls, and genuine overflow.

Activity SummaryPublished candidate:
Final exact committed validation: The actual public Jim witness preserves the existing function-free package/report bytes and refuses called source functions at the old schema boundary with no outputs. Binary Validation boundaries: the original default Rust test-thread nested-expression stack abort is retained, not credited as an attribution RED; the attribution unit uses 8 MiB and the actual normal CLI process is covered separately. Cleanup stops launched process-group members and does not prove cleanup of escaped sessions. New Echo provider/runtime execution remains downstream. All product validation used the existing bounded Docker worker and canonical shared lease; worker shutdown and lease release succeeded. @coderabbitai review — please re-review the published fixes and current candidate, including the resolved thread evidence. The previous changes-requested review is not being treated as approval. |
Independent adversarial review: Edict PR #228 final review follow-upAPPROVE for the compiler/contract change at
Review continuity and scopeThis review carries forward the complete original production-path audit and the five mechanical hosted-Clippy assertion corrections at The current PR body contains Production-path reviewThe authored Signatures are collected before bodies. Each function gets a separate lexical environment and deterministic positional parameter/local identities. Duplicate declarations, invalid shadowing, captures, forward locals, incompatible argument/results and invalid unused definitions refuse. The accepted body is pure immutable bindings followed by a terminal return; effects, requests/reads, assertions, loops and unsupported statements do not silently disappear. Target validates every function body, including unused bodies, and checks partial-operation totality without borrowing caller input proofs. Calls retain ordered argument occurrences and their conditional, predicate and pre-body placement. The source-owned function table is distinct from validated lawpack facts. Every imported call still needs its exact authenticated signature/type/cost authority. Declaration-wide collision checks use canonical imported coordinates. Source-call graph edges are determined by exact declared membership, so a disjoint imported export can share a package coordinate without becoming an invented source definition. Missing facts and unknown exports still fail independent Target admission. The source graph uses active-path cycle detection and completed suffix heights. A leaf has height one; every caller includes its child's completed height, including reused suffixes. The 128/129 boundary and shared-suffix controls prevent traversal-order-dependent acceptance. Validated graph membership precedes indexed lookups, and bounded height arithmetic cannot overflow. Repeated call occurrences remain distinct for checked transitive cost composition even when graph edges are deduplicated for height analysis. Cost memoization uses original, immutably borrowed AST expression identity rather than diagnostic spans. Branch-yield traversal no longer clones statements and loses their identity. Callee syntax, predicate-only nodes, folded negative-literal children and an existing intent yield wrapper are not additional typed-value expressions. Boolean predicate reification now includes the synthetic Nonempty source-function tables force Target semantic closure to bind the complete Core digest, including unused functions and require-only programs. Parameter/local alpha-renaming preserves canonical identity; changed executable bodies change it. Empty tables are omitted, preserving function-free bytes. The new public Rust struct field requires Rust struct-literal callers to supply it; wire compatibility is not a promise of unchanged Rust construction syntax. Findings resolved during review
The previously considered huge-string overflow lead is withdrawn for function-bearing modules: checked operand storage bounds reject the proposed huge operands before concatenation reaches that addition. It is not listed as an unresolved finding. The source expression-occurrence limit is a narrower bound, not an advertised global parser/validator resource theorem. Eight reviewed findings and final remediation
The original graph-expression unit invocation aborted on Cargo's default test-thread stack before its intended assertion. That failed setup remains explicit. The attribution witness uses an 8 MiB test thread; the equivalent real CLI subprocess on its normal stack does not abort. Neither observation proves a global parser/validator resource cap or safety on every caller's stack. The RED/GREEN evidence and exact final gateEvidence names identify retained raw logs/manifests/exports; they are not invented repository fixtures. The reviewer independently inspected their contents and source binding.
The public harness directly hashes the preserved phase manifest; its hash equals the independently verified host manifest. The final binding does not depend on the explicitly documented applied-manifest reconstruction used during the much earlier 6eb control run. The final execution script verifies all compiler and Jim inputs before and after the command, disables incremental compilation, and invalidates the affected workspace output before rebuilding. Real public old-provider boundaryThe harness uses Jim application/vendor input
Function-free package SHA-256 remains Contract and compatibility checks
The new schema permits an optional nonempty source-function table with typed parameters, return type and pure body. The final schema test accepts function-free modules under both versions, accepts function-bearing modules only with explicit new-schema selection, and rejects incomplete signatures and explicit empty tables. The five contract resources, eleven contract roots and seven domain roots are unchanged; embedded resource digests match. The owner generator checks the new publication without rewriting the frozen pair. Existing canonical goldens pass. No provider or application pin was silently migrated. All added/changed topic rows were reviewed against their requirements, named test bodies, fixture paths and links. The final CLI wording distinguishes emitted table/digest observations from the compiler suite's argument-order proofs and from the external provider witness. Source-depth documentation explicitly says source-function paths, not a combined source-plus-imported limit. The final legacy regression additionally compares both assembled CDDL and manifest bytes directly with the frozen pair, making the previously manual exact preservation check durable. All newly added CLI/compiler topic IDs are unique, named test evidence exists, affected relative links resolve, and their oracles match the asserted behavior. Documentation records request-containing-value refusal even when the source function is unused. Resources and reviewer boundariesThe executor reused the established The run used Rust 1.96 with incremental compilation disabled, 4 CPUs, 6 GiB memory, a 1,200-second deadline, bounded container logging, and the existing fail-closed monitor over writable layers, temporary/shared-memory storage, caches, host scratch and logs. Monitoring failure or limit/timeout stops the owned worker and host process group. Final recorded usage was 12,385,617,820 B build, 4,251,711,388 B data, 12,624,458 B logs, below 20 GiB / 4 GiB / 128 MiB. Host/VM free space was 717,598,674,944 B / 682,105,180,160 B, above 50 GiB. Data headroom was only 43,255,908 B at that measurement; these are phase-specific measurements, not permission to skip fresh accounting for later work. The repository's codex-think helper is unavailable on this host. Current source/history and concrete evidence were used instead. This external review report is outside the repository; no repository commit or publication by this reviewer is implied. Hosted review cutoff and remaining limitationsComplete paginated comments, submitted reviews, review threads and nested comments were independently refreshed at approximately 2026-10-05 09:43–09:44 UTC and compared with the prior immutable c585 export. The collection contains 12 comments, 9 submitted reviews and 8 threads; all eight threads are resolved with published commits and inspected evidence replies. The original eight findings remain part of the reviewed history. The eight later submitted reviews are the author's COMMENTED replies, not independent approvals. The live metadata binds the exact head/base above. All five hosted CI jobs are SUCCESS: Rust MSRV 1.96, Rust stable, release-date reconciliation, Windows containment and supply-chain. CodeRabbit is actively processing c585→c1fc; its status is PENDING and the PR review decision remains the prior CHANGES_REQUESTED. Seven original finding comments already append addressed acknowledgments, but neither those acknowledgments nor thread resolution substitutes for its required approval. Hosted Codex again reports a usage limit, which is unavailability rather than approval. The final Code Lawyer reconciliation and active bot gate remain with the merge owner. Refresh all time-sensitive states before merging; new feedback or commits require reconciliation. Remaining scope limits:

- Around line 1170-1183: Add a span assertion to the request-shape loop in
request_value_shapes_are_unsupported_in_source_accounting_not_overflow,
verifying that the UnsupportedSourceShape error points to the hidden declaration
(or the parameter span if that is the intended diagnostic location). Use the
existing source/span helpers and keep the assertion valid for each test input.
Review comments at @scripts/consumer-witnesses/test_jedit_source_functions.py:
- Around line 44-65: Remove the redundant `compiler.pgid` cleanup block from the
test around `witness.build`; `build` already calls `stop_group(child)` in its
`finally` path to terminate the compiler process group. Keep the
descendant-survival assertion, and do not replace the cleanup with error
suppression or another marker-based kill.

The review must check the diagnostic changes, exact legacy bytes, request classification, process-group cleanup, CLI regression, and return-check extraction. Your reported validation supports the review but does not replace independent checks. The previous changes-requested review is not approval. Echo provider/runtime execution remains outside this PR. If you found this review helpful, would you consider giving us a shout-out on X? Thank you for using CodeRabbit!

Its retained local report has SHA-256 The complete production audit remains applicable: parsing/signature collection reaches typed executable source-owned Core definitions and independent Target admission; imported facts remain provenance-authenticated and separate; lexical frames prevent captures and invalid forward references; ordered arguments and bindings retain their occurrence identities; body restrictions/totality are checked even for unused functions; exact source membership owns call edges; shared suffix heights and checked repeated-call costs preserve depth and cost bounds; AST identity rather than spans keys the cost cache; synthetic Boolean storage is charged; canonical closures bind changed bodies; and empty tables preserve function-free artifact shape.

Plain-English Walkthrough
TL;DR
Edict now compiles typed, nongeneric, nonrecursive pure
fndeclarations, including Jim's authored byte-assembly helper. Functions retain ordered immutable bindings, a terminal return, and explicit calls through Core and Target lowering. [claim:source-functions, confidence:0.99]Walkthrough
Previously, the public compiler refused
fndeclarations. A function such as this can now be called from authored Edict:The compiler resolves signatures before bodies, checks every definition including unused ones, and gives each function a fresh lexical frame. Calls retain one occurrence of each argument in source order, including unused arguments; conditionals and predicates retain their placement and laziness. This PR establishes emitted structure and language semantics. Runtime evaluation remains a consumer obligation. [claim:frames-and-calls, confidence:0.99]
Executable source definitions live in
CoreModule.functions, separately from authenticated lawpack facts. Independent Target validation checks complete function bodies for types, authority and totality. Source and imported definitions cannot claim the same canonical coordinate; disjoint exports may share a package coordinate. [claim:function-authority, confidence:0.99]The flow keeps these two authorities explicit:
flowchart LR S[Authored function declarations] --> C[Compiler checking] L[Authenticated lawpack facts] --> C C --> K[Core with source function table] K --> T[Independent Target validation] L --> T T --> A[Target artifact bound to Core digest]Caption: Source definitions and imported authority
Changing a function body, signature or unused definition changes Core identity. Renaming local binders preserves identity. Empty function tables are omitted, and function-bearing modules always bind the complete Core digest in Target's semantic closure. [claim:function-identity, confidence:0.99]
Checked transitive cost summaries count repeated calls and unused arguments. They include bounded value storage, validation, byte comparisons and generated Boolean operands; diagnostic spans cannot change budget acceptance. The 128-frame check concerns source-function paths. Imported-body height and backend metering still require independent consumer admission. [claim:bounded-compilation, confidence:0.99]
Well-typed non-Boolean predicates report
ExpectedPredicate. Rejected function statements retain their exact spans, and graph failures carry structured ownership instead of inferring a function from diagnostic text. Request-bearing values are currently unsupported by accounting in modules containing source functions, including unused functions; their diagnostic isUnsupportedSourceShape, while true numeric overflow remainsInvalidBound. Function-free request behavior is preserved. [claim:diagnostics, confidence:1.00]The generator now writes the explicitly selected
fixtures/provider-contracts/source-functions-v1/pair. The priorv1CDDL and manifest remain byte-for-byte unchanged; function-free Core encoding remains unchanged. Selecting a new schema does not automatically upgrade an existing provider. [claim:explicit-publication, confidence:0.99]This compiler change is independently mergeable: a real Jim function-free build still produces a package and verification report with the pinned old provider; function-bearing source receives
InvalidProviderInvocation/ArtifactSchemaMismatchforcore.artifact, with no outputs. [claim:old-provider-boundary, confidence:1.00]Scope and dependencies
Compiler acceptance is not Echo runtime support. Echo #752 owns provider admission, independent verification, combined source/imported call-depth checks, and generic execution in both pure and bounded-read programs. This PR adds no Jim-specific Echo primitives. Recursion, generics, higher-order functions, effectful bodies, function-body assertions, variant/match expansion, new byte escapes, and completion of Jim's decoder or rope remain outside this change. Existing Target eligibility and result-projection restrictions remain documented in the source-function reference. [claim:consumer-boundary, confidence:0.99]
Documentation updates cover syntax, scope, Core identity, compiler bounds, Target authority, public CLI behavior and explicit contract selection. No dependency was added.

This is not a guarantee for arbitrary caller stacks. The Python regression proves cleanup of surviving members of the launched process group, including successful parent exit; it does not establish cleanup of processes that escape that group.The first validation attempt at this same candidate was stopped by the 4 GiB data guard and is incomplete; the results above come from a fresh, fully completed retry after lossless compression of completed snapshots and byte-verified duplicate removal. The guard and budgets were unchanged.
All executed builds, tests and formatting used the existing guarded Docker worker and shared resource lease. No host product checks ran. [claim:validation-evidence, confidence:1.00]
