Queue authority and operator baseline

This Draft remains TEPP's delivery/queue-authority vehicle. Protected product authority is main@a243f18da4a4ca8a8d068c39922537f1f8ed6ad0; PR=0 is valid only after protected merge or a verified successor has inherited every valid delta/test/fixture/contract/evidence item. Simple Close is not queue reduction.

Current exact head of this Draft is a9b9ceeb6ac61f66091e08a38b3bee94939df39f. Its central-scheduler repair preserves manual workflow_dispatch, requires # cwl-org-commercial-entrypoint: v1, and rejects repository-local schedule:/cron reintroduction. No provider credential, required-check, security threshold, or merge permission is weakened.

docs/product-technical-gap-baseline.md and docs/TRACEABILITY.md are this lane's canonical checked-in authorities. Historical snapshots may remain as history, but current-state sections must not describe predecessor PR heads, raw LCOV populations, predecessor artifact digests, or review-rate-limit responses as live authority.

Live foundation chain

Rust 1.98.1 prerequisite #494

#494 is Draft/open/mergeable at exact 97e10a646ca43babcf06c6e36d5bd8f6b1c3b16a on protected main@a243f18.... A narrow ARCHITECTURE.md edit at 54ed1dcc... was rejected by exact diff inspection because it unintentionally omitted three existing architecture-table rows. Ordinary forward repair 97e10a... restored those rows; comparison from predecessor ea2e5ec... to 97e10a... has no file delta. No force update or destructive rebase was used.

The intended code-current finding therefore remains unresolved: ARCHITECTURE.md still says Stable Rust 1.98.0 is the compile/lint/test/line-coverage reference although the root build-reference/CI/verifier pin is 1.98.1. Repair that sentence only. Cargo.toml rust-version = "1.98.0" remains the MSRV; the immutable Docker build image remains 1.98.0 until a verified 1.98.1 Bookworm digest exists.

Fresh exact-head workflows for 97e10a... are terminal: Documentation Quality 34564877786, Rust Foundation 34564877774, Security Scan 34564877776, and SAST Semgrep 34564877798 are GREEN; CodeQL PR 34564877779 is RED in delegated compatibility receipt settlement. Language detection 103154836880 and current-head dispatch 103157070548 are GREEN. Python 103155462817 and actions 103155462854 both successfully read the current-head verdict and fail only at Release runner or enforce current-head CodeQL verdict. The canonical .github#2040@6706c231... owner path is also terminal GREEN in Security/Semgrep/Python Security/Agent Review Runtime and RED in CodeQL 34251822255, where attempt 7 fails in the central verdict/dispatch path. TEPP must not fabricate a receipt, rerun-loop no-op leaf commits, or fork the control-plane fix locally.

After #494 lands normally, descendants based on the current protected main must be integrated/restacked non-force and exact-head evidence reacquired rather than transferred.

Central hourly admission #492

#492 remains intentionally Draft, not Ready for Review, at exact 794ba9e6dda9f043aa499920fdf609b81b075d7e, open/mergeable on current protected main. Its local-schedule/parser repairs remain valid, but the leaf commercial-development workflow still embeds provider credentials and mutable contextual-orchestrator bootstrap/routing.

.github#2038 owns the central reusable-worker/thin-caller policy. contextual-orchestrator #1023 owns the released Actions-facing gateway/auth/provenance and consumer-safe authentication contract; #1083 owns publication of the immutable orchestrator/free release. Until those contracts are immutable, TEPP must not copy provider routing/credentials/model selection or consume mutable contextual-orchestrator source as production authority. The stale AGENTS.md provider-key guidance belongs to the same eventual consumer migration.

Validation Evidence #488 / issue #491

#488 remains the owner-correct Validation Evidence landing vehicle stacked on #492@794ba9e6..., Draft/open/mergeable at exact 520df488fd86ba48008af8ee5a2e112b4587fc22.

The public route attempts the checked O(n) neutral-zero exact proof for every n >= 3 with exactly represented finite residuals. O(n²) pairwise reference is used only after O(n) refusal at n <= 16; above sixteen, refusal delegates directly to the established bias implementation without quadratic pair scratch. n=2 keeps its direct identity.

Repository-owned numerical evidence now separates exact-real positivity from floating implementation proof. docs/research/validation-bias-dispersion-positivity-bound.md proves for every admitted general translated path n >= 3 that canonical translation supplies exact zero and a maximum normalized magnitude x with 1 <= |x| < 2, so D = n Σy² - (Σy)² = Σ_{i<j}(y_i-y_j)² >= n x²/2 >= n/2. That theorem does not authorize removing dispersion_numerator <= 0.0: the implemented path rounds each square, sorted compensated first and second moments, usize -> f64, n*Q, and the final FMA. Source removal still requires an implementation-matched absolute forward-error bound strictly below n/2 over the admitted metric domain or a compact caller-valid represented-input counterexample.

The target-width and square-root correction-exhaustion obligations remain closed. validation_core admits 64-bit production pointer-width targets; the former denominator-width branch was removed only after the successful u128 perfect-square proof made it impossible. docs/research/validation-bias-standard-error-seed-distance-bound.md owns the strict <3 adjacent-binary64 seed-distance theorem, and production source applies exactly three exact corrections.

docs/research/validation-bias-production-resource-admission.md now owns the resource/cardinality boundary. analysis_engine::MAX_EVIDENCE_UNITS = 100_000 bounds Analysis Run evidence admission, but analysis_engine has no current validation_core dependency and AnalysisEvidenceUnit is evidence identity/time/membership metadata rather than a truth/recovered metric pair. There is no typed/versioned proof that every supported product bias-SE call comes through AnalysisCorpus, or that one evidence unit equals one bias-SE sample. Therefore 100_000 is not a validation_core sample cutoff and must not be used to delete numerical refusals. The next buyer-path repair is an explicit evidence-to-metric cardinality contract.

The helper false-zero branch remains scientifically/source-domain reachable through the n=2^54 minimum-subnormal construction. The normalized SE is 2^-54; exact restoration is 2^-1075, which ties to represented zero. Materializing only the two public f64 input slices requires 2^58 bytes = 256 PiB before working storage, so a giant allocation is not realistic product acceptance. Preserve the guard and close product acceptance through bounded representation/resource/cardinality evidence, not source rewriting or an arbitrary public-library cutoff.

Exact-head 520df488... workflows are terminal. Documentation Quality 34573224170 and Bias SE Exact-Proof Budget 34573224257 are GREEN. Rust Foundation 34573224268 is RED only in Production line and branch coverage job 103179819615; Live PostgreSQL 103179819441, Rust format/lint/test/rustdoc/dependency policy 103179819679, and repository/Python contracts + SBOM/provenance 103179819783 are GREEN.

Current immutable coverage authority is 12,344/12,346 authored production lines from artifact 10188730908, archive digest sha256:f6c560819690274ad205baf77ec46089835d5563e7bbcb3d2f941fb532e63ff0, with only bias.rs:69 and bias.rs:592 zero-count; and 4,450/4,452 unique source branch arms from artifact 10188776666, archive digest sha256:34006fb155957e34a86385cd9975340fa24bdb1950874c07e9d001e0070a1088, missing bias.rs (68,8)-(68,29) TRUE with folded counts (0,12) and (591,8)-(591,35) TRUE with (0,32). The exact-head delta from 3b5d07b... is documentation-only, and the current LCOV has the same 42,005 source/line DA keys and same two zero-count records; raw LLVM/instrumented totals are not the product authored-source denominator.

The earlier CodeRabbit rate limit is no longer current authority. The retried exact-head review completed on 520df488... with no findings in the requested resource/cardinality scope. It independently confirmed that the repair is documentation-only, keeps MAX_EVIDENCE_UNITS distinct from bias-SE sample cardinality, preserves the n=2^54 source-domain witness as resource-extreme rather than a realistic fixture, and leaves translated-dispersion floating positivity unresolved. This is review evidence only, not numerical/scientific acceptance. Formal submitted reviews remain historical COMMENTED; unresolved inline review threads are zero; there is no qualifying current-head approval.

#491 remains open with the same current authority. The isolated n=2,047 candidate/fallback measurements remain characterization only: candidate p95 23,306 ns, max RSS 2,176 kB, zero pair-record scratch; fallback p95 15,385,815 ns, max RSS 100,152 kB, 2,094,081 pair records / 100,515,888 bytes explicit scratch. These are not buyer HTTP p95 guarantees.

This Draft's own merge bar

On a9b9ceeb6ac61f66091e08a38b3bee94939df39f, Rust Foundation 34180704494, Documentation Quality 34180704456, Security Scan 34180704429, and SAST Semgrep 34180704485 are terminal GREEN. CodeQL PR 34180704464 is terminal RED and remains delegated control-plane evidence, not permission to fabricate a receipt or weaken the gate.

Historical review submissions are COMMENTED; there is no qualifying current-head approval. Ready/merge is not claimed.

Release / ownership boundary

Reusable static/generalized psychometric arithmetic remains fast-mlsirm-owned through an immutable released/versioned Published Language/ACL. Semantic LLM routing remains contextual-orchestrator-owned through an immutable released orchestrator/free API/client/schema contract. contextual-orchestrator #1023 and #1083 remain open owner gaps and its GitHub Releases remain empty, so mutable CO source is not TEPP production authority.

A release-ready protected TEPP head still requires code-current PRD/TRD/architecture/ADR/TRACEABILITY/product-gap evidence, exact protected-head Rust/documentation/security/review gates, 100% owned-production authored line+branch coverage without tricks, scientific/recovery acceptance, immutable dependency contracts, version/CHANGELOG/tag/package/SBOM/provenance/reproducibility/rollback evidence, and no unresolved scientific/privacy/security/supply-chain blocker.

Preserve Draft/Proposed state while these conditions remain unresolved. Integrate forward non-force, do not self-approve or destructively rebase, and do not transfer predecessor checks/reviews after a head or base changes.

Validation/docs handoff for the canonical queue-authority lane: #488 is now exact 5ff6cddd3c18c4d2809c39b901c865d09d92f0b3, stacked on Draft #492 exact 794ba9e6dda9f043aa499920fdf609b81b075d7e. Documentation Quality 34461301178 is GREEN; Rust Foundation 34461301216 is RED only on authored production coverage. Current immutable branch artifact 10145786163 (sha256:d4c6650afee3c72c4024e3c09ae81157bd194f56867963a38be4d8f391196cff) folds to 4,453/4,460, 7 missing arms, all in validation_core/src/bias.rs; line artifact 10145728799 (sha256:c60d0ecf5f82aa44039e6fb3f23108fe8917543a58a67b77ad319c5aa32a5b4c) leaves six authored production lines (bias.rs:68,109,591; bias_se.rs:247,272,288). Please use this authority in the next docs/product-technical-gap-baseline.md / TRACEABILITY refresh rather than the stale #488 SHA and #492 Ready-for-Review snapshot currently in #435. Protected main remains a243f18da4a4ca8a8d068c39922537f1f8ed6ad0; TEPP and contextual-orchestrator still have no immutable GitHub release, so no mutable CO consumer authority is implied.

TEPP Validation Evidence owner handoff — current #488 authority advanced to e9447e4138f757aa903bf824ffc9ceefe03dcec1 on prerequisite #492@794ba9e6dda9f043aa499920fdf609b81b075d7e. Documentation Quality 34464259021 is GREEN; Rust Foundation 34464259047 is RED only on authored production line/branch completeness, with Rust fmt/Clippy/no-retry tests/doctest/rustdoc/dependency policy, repository/Python+SBOM/provenance, and Live PostgreSQL GREEN. Immutable branch artifact 10146942502 (sha256:e5bfdfb3ccb74475413d7bf9dd8e12b1128ab715ead6dc8005ab16ef353ab3e4) folds to 4,452/4,458, 6 missing arms; line artifact 10146898125 (sha256:fedf08df0224b92fa7b61e3c39e1791d586cd0bf626bc4d06e7220452a4e67a7) leaves bias.rs 69/109/595 and bias_se.rs 247/272/288. This head removed only the provably impossible translated-dispersion non-finite disjunct; no coverage exclusion/denominator/test payload change. Please use this exact authority when refreshing docs/product-technical-gap-baseline.md and TRACEABILITY. #492 is still Draft, not Ready, and TEPP/contextual-orchestrator still have no GitHub release; do not encode mutable CO/provider routing as current product authority.

Canonical docs refresh input from current Validation Evidence lane: #488 is still exact e9447e4138f757aa903bf824ffc9ceefe03dcec1, Draft/open, stacked on Draft #492 794ba9e6dda9f043aa499920fdf609b81b075d7e; protected main remains a243f18da4a4ca8a8d068c39922537f1f8ed6ad0. Current immutable branch authority is 10146942502 (sha256:e5bfdfb3ccb74475413d7bf9dd8e12b1128ab715ead6dc8005ab16ef353ab3e4) at 4,452/4,458 with 6 missing arms. Line artifact 10146898125 leaves bias.rs 69/109/595 and bias_se.rs 247/272/288.

Fresh source mapping further corrects the trace: bias_se.rs 247 and 272 are Option-propagation lines from the exact candidate-square and exact midpoint-square comparison helpers, while 288 is the independent four-pass correction-exhaustion return. #488 comment 5617778783 records the bounded-dyadic proof obligations; #491 comment 5617781461 keeps this separate from any n>16 activation. Please use this mapping in the next TRACEABILITY / product-technical-gap refresh rather than the older generic “three refusal exits” wording. No provider-routing or mutable contextual-orchestrator dependency is implied.

Remaining branch arms are bias.rs line 68 true, line 106 false, line 153 true, and line 594 true.

Please use this exact authority when refreshing docs/product-technical-gap-baseline.md and docs/TRACEABILITY.md; the current #435 body still contains older #488 heads and describes #492 as Ready, while a fresh #492 read reports Draft. Protected main remains a243f18da4a4ca8a8d068c39922537f1f8ed6ad0. TEPP and contextual-orchestrator GitHub release inventories are both still empty, so docs must continue to describe semantic-LLM consumption as blocked on an immutable released owner contract rather than mutable source/provider credentials.

Its immutable current branch authority is artifact 10153649925 (sha256:622c8d2ead67c25894683509de6e509064f0b72c4e896f9670aa9251040e8e61), 4,449/4,452 covered, 3 missing arms; line artifact 10153584662 (sha256:e9c4c4925969b009da108c79f64c8ec1585ad4518a2f3277c1d7d15061b9fdd8) is 41,972/41,977, missing bias.rs:69,590 and bias_se.rs:247,272,288. Documentation Quality is GREEN; Rust Foundation is RED only on authored-production 100% line/branch enforcement.

#492 is Draft, not Ready for Review, and remains intentionally blocked on immutable .github/contextual-orchestrator orchestrator/free owner publication. Protected main remains a243f18da4a4ca8a8d068c39922537f1f8ed6ad0. TEPP and contextual-orchestrator releases remain absent; fast-mlsirm latest immutable release remains v0.9.1.

The #435 body still carries an old #488 head and describes #492 as Ready. Preserve historical text if useful, but docs/product-technical-gap-baseline.md / docs/TRACEABILITY.md must use the live Draft/head/artifact state above on the next canonical docs write. A focused current-head CodeRabbit review was requested on #488 for the three branch arms plus the bias_se exact-rounder zero-hit exits; no review result is being treated as evidence until it is actually returned.

Canonical docs handoff from the Validation Evidence lane: #488 has advanced to exact head f5c1d2ea2f666332562a5c48c49c494bf56e37bb. Its PR body is now current. #492 remains exact 794ba9e6dda9f043aa499920fdf609b81b075d7e, intentionally Draft/open; do not retain the older Ready for Review wording as current authority.

#488 now has a dedicated release-mode exact-proof resource-evidence workflow. The first mechanical success was rejected because it measured GitHub's synthetic PR merge SHA; f5c1d2ea... repairs the provenance contract by checking out and verifying the actual PR head. Exact-head run 34501459910 is GREEN with immutable artifact 10162024540 (sha256:61e64246ab1a9ab40a24b9228e790f207bdbed54a6097c56d6439ea50656a681). The candidate wide hybrid records zero pair-record scratch on every measured geometry and p95 11,652ns at compact n=2,047; at odd n=65 it records 812ns/0B versus narrow-pair fallback 6,532ns/99,840B. Whole-process max RSS 124,800kB is not candidate RSS because the same comparison process executes a buffered n=2,047 kernel with 100,515,888B scratch.

Do not convert this into n>16 activation language. It is characterization evidence only. The last completed source-head coverage authority remains 3 missing bias.rs branch outcomes and three authored line misses; current-head Rust Foundation is being reacquired after the CI-only commits. .github#2038 and contextual-orchestrator #1023/#1083 remain open owner prerequisites for the released orchestrator/free contract. Refresh docs/product-technical-gap-baseline.md and docs/TRACEABILITY.md from these live facts while preserving older snapshots strictly as history.

TEPP Validation Evidence authority handoff from current #488 exact head f5c1d2ea2f666332562a5c48c49c494bf56e37bb for the canonical docs lane.

Please refresh docs/product-technical-gap-baseline.md / docs/TRACEABILITY.md from this live evidence rather than the stale #488/#492 snapshot currently in this PR body:

It records Rust 1.98.0/LLVM 22.1.8, AMD EPYC 7763, release build, 25 timing samples, exact scratch shape and process /usr/bin/time -v evidence. Candidate hybrid_narrow_wide_pair p95 is 11,652 ns at compact n=2,047 with zero pair-record scratch; buffered quadratic is 26,278,488 ns with 100,515,888 scratch bytes. Whole comparison-process max RSS is 124,800 kB, so do not label that as isolated candidate RSS/allocator evidence.
  • CodeRabbit exact-head review found no provenance/security/reproducibility finding in the evidence workflow, while confirming that RSS limitation.
  • This does not activate n>16; validation: replace bias-SE sample-count staircase with measured exact-proof budget #491 is now current and still requires isolated candidate/fallback allocator/RSS, deterministic/refusal/permutation evidence, applicable buyer-path p95, full coverage/security/docs GREEN and qualifying review before any budget widening.
  • fix(actions): align central hourly admission contracts #492 is Draft/open, not Ready. The immutable released orchestrator/free owner path remains .github#2038 plus contextual-orchestrator #1023/#1083; TEPP must not consume mutable provider-routing source.

Preserve historical snapshots as history, but do not present them as current authority.

This fixes the earlier mixed-process RSS attribution gap but does not activate n>16 and is not HTTP buyer-path latency.

The checked-in gap/TRACEABILITY authority must also correct the old sample-count statement: public validation_core::bias_standard_error currently attempts the checked O(n) exact neutral-zero proof for every n >= 3; only the O(n²) pairwise reference/fallback is capped at n <= 16, and an O(n) proof refusal above sixteen delegates directly to the established bias implementation without quadratic scratch.

Docs-owner refresh after exact review/fix: CodeRabbit confirmed #488 production routing at bace14c6836014c37be67f0505d797ff28f0f643 and found four stale route descriptions. Those four #488-owned surfaces are now repaired in documentation-only commits ending at 86a951ef1a6e5125a53ee0e8776a182136ea3141: docs/OPERABILITY.md, CHANGELOG.d/validation-bias-exact-proof-budget-characterization.md, docs/research/bias-standard-error-wide-linear-admission-bound.md, and docs/research/validation-bias-standard-error-exact-proof-budget.md. Current wording matches source: O(n) neutral-zero proof eligible for every n>=3; O(n²) pairwise reference only after refusal at n<=16; refusal above sixteen delegates directly to the established bias implementation.

Please use 86a951e... as the Validation Evidence docs input when refreshing the canonical docs/product-technical-gap-baseline.md / TRACEABILITY lane. #492 remains Draft at 794ba9e6...; do not carry the older Ready-for-Review label or the old n=4..=16 production-cutoff statement forward. Current exact-head Documentation Quality 34525141769 and Bias SE Exact-Proof Budget 34525141856 are GREEN; Rust Foundation 34525141632 is still running, so predecessor coverage artifacts remain historical until the current-head artifact is emitted.

  • Validation Evidence head advanced normally to a063bd238ce838ea28e40e14151aeed8ea05cc2a on unchanged prerequisite #492@794ba9e6dda9f043aa499920fdf609b81b075d7e.
  • validation_core now has an explicit production 64-bit pointer-width contract (8949faf...) backed by compile-time refusal and usize::BITS == 64 / u128::MAX.isqrt() == usize::MAX as u128 test; ADR 0001 records the numerical/resource scope (ce9bddc...). This is not an x86-only or workspace-wide claim.
  • Independent exact-head review proved the former bias.rs:148 denominator > usize::MAX as u128 branch impossible after successful u128 perfect-square proof on the supported 64-bit domain. 8060c90... removed only that disjunct; a063bd... updates the changelog. Exact-head re-review found no cast-safety or fail-closed regression.
  • Do not carry the predecessor c1b31a... coverage artifacts forward as current. On a063bd..., Bias SE Exact-Proof Budget 34549643067 is GREEN, while Documentation Quality 34549643113 and Rust Foundation 34549643073 are still queued. Current immutable line/branch artifacts and totals are therefore pending.
  • Remaining numerical obligations are the resource-extreme but source-domain-reachable lower-level false-zero refusal, translated dispersion_numerator <= 0 pending proof/witness, and bounded correction exhaustion pending a small seed-distance proof. A proposed n=2^55 three-level dispersion witness was independently falsified because canonical translation/normalization changes it to [-1,0,+1,...]; the repository's actual Neumaier state yields positive fused dispersion 2^108, so the guard remains.
  • Please replace docs(ddd): restore queue authority and bounded-context ownership #435's stale bias.rs:148 target-ambiguity paragraph and predecessor fix(validation): preserve representable recovery metrics #488 head/artifact snapshot in docs/product-technical-gap-baseline.md / docs/TRACEABILITY.md current-state sections when this lane next writes. Preserve historical snapshots as history, not current authority.

No source write is being made on #435 from the Validation Evidence writer.

#488 / #491 current-authority handoff after terminal exact-head coverage on a063bd238ce838ea28e40e14151aeed8ea05cc2a:

  • Bias SE Exact-Proof Budget 34549643067: GREEN.
  • Documentation Quality 34549643113: GREEN.
  • Rust Foundation 34549643073: RED only at production line/branch coverage; repository/Python+SBOM/provenance, Rust format/Clippy/no-retry tests/doctests/rustdoc/dependency policy, and Live PostgreSQL are GREEN.
  • line artifact 10180477049, digest sha256:51bc95d76c23229297eaa0d454d7abb3dbf034c1b9f526a2e6904c859f3ae1b1: 41,991/41,994 authored lines; zero-count production lines are bias.rs:69, bias.rs:592, bias_se.rs:307.
  • branch artifact 10180508280, digest sha256:0693c2110bffb31c71258ab251474fec0e55435a306208b494f83a0a33239f60: checked-in unique-source/per-arm-max fold is 4,450/4,452; only bias.rs (68,8)-(68,29) TRUE and (591,8)-(591,35) TRUE remain uncovered.

The former target-usize denominator arm is no longer a current gap: #488 first established the validation_core 64-bit production target contract (8949faf..., ADR update ce9bdd...), then removed only the proven-impossible denominator-width disjunct (8060c90...), with exact-head CodeRabbit re-review clean. The authored-line total stays unchanged because that deleted || continuation is excluded by the checked-in authored-line classifier and the added target-contract test is under #[cfg(test)]; branch coverage genuinely improves from the predecessor 4,451/4,454 to 4,450/4,452.

Please update the canonical current-state sections of docs/product-technical-gap-baseline.md and docs/TRACEABILITY.md on this docs/queue lane so they no longer list the resolved target-width arm or predecessor c1b31a... as current #488 authority. Preserve historical snapshots as history. #492 remains Draft at 794ba9e6...; do not describe it as Ready or copy unreleased contextual-orchestrator routing into TEPP.

Validation Evidence handoff — replace the stale #488 snapshot in the next canonical docs/queue-authority update; do not transfer predecessor checks as current.

Current #488 exact head is 71c42ddd2c4087b027f977192fe2d7f87b24d931, still Draft/open/mergeable on #492@794ba9e6dda9f043aa499920fdf609b81b075d7e.

Exact-current evidence:

  • Bias SE Exact-Proof Budget 34557236352: GREEN.
  • Documentation Quality 34557236234: GREEN.
  • Rust Foundation 34557236172: RED only at production line/branch coverage; repository/Python contracts + SBOM/provenance, rustfmt, Clippy, no-retry tests, doctests, rustdoc, dependency/license/source policy, and Live PostgreSQL are GREEN.

New repository-owned evidence: docs/research/validation-bias-standard-error-seed-distance-bound.md derives, under the current checked numerator/denominator/exact-power-of-two/finite-positive-seed contract, a strict <3 representable-step seed distance. That means at most two neighbor advances and a following exact square/midpoint decision; the current four-pass loop is conservative on the stated finite-result domain. This supersedes the old #435 wording that repository-owned derivation was still absent. It does not resolve the translated-dispersion or resource-extreme false-zero branches, and it is not a coverage waiver. Exact-current independent review was requested in #488 comments 5628978141/5628988551; source simplification is not yet claimed.

Please carry this state into docs/product-technical-gap-baseline.md and docs/TRACEABILITY.md on the #435 single-writer lane, preserving #492 as Draft and the existing owner/release boundaries.

Correction to my immediately preceding Validation Evidence handoff: the exact-current production authored-line authority for #488@71c42ddd2c4087b027f977192fe2d7f87b24d931 is 12,341/12,344, not 41,991/41,994. The three authored misses are unchanged: bias.rs:69, bias.rs:592, bias_se.rs:307.

The larger number came from the raw/instrumented LCOV population; canonical production authority is the checked-in authored-source classifier in scripts/check_coverage.py. Branch authority is unchanged at 4,450/4,452, missing only bias.rs (68,8)-(68,29) TRUE and (591,8)-(591,35) TRUE.

Exact-current independent review of docs/research/validation-bias-standard-error-seed-distance-bound.md found no numerical issue, confirmed its current source preconditions, and agrees bias_se.rs:307 is unreachable for current admitted inputs. It also recommends retaining the terminal fail-closed None as a future-contract defense. Therefore do not copy 41,991/41,994 into docs/product-technical-gap-baseline.md or docs/TRACEABILITY.md, and do not describe line 307 as lacking a mathematical bound; the remaining line-307 gap is policy/coverage reconciliation without weakening the fail-closed contract.

Validation Evidence provenance correction for the next canonical docs refresh: I re-read the exact #488@71c42ddd2c4087b027f977192fe2d7f87b24d931 GitHub Actions artifact metadata instead of carrying a locally reported digest label forward.

The canonical GitHub Actions artifact archive digests are:

  • line artifact 10183119528: sha256:8c45a8133b7f414cb702d07ef52d4258a4df7c3313c0fcfdac3055ccc6c59ed1;
  • branch artifact 10183153145: sha256:6ba11a2841019e2515deaea5fe87a874f781ff5587e2ea738da16ca166426ad1.

#488 and #491 authority have been corrected to name these specifically as GitHub Actions artifact archive digests. Coverage authority remains 12,341/12,344 authored production lines and 4,450/4,452 branch arms; this is provenance repair only, not a coverage change. Please use these archive digests if docs/product-technical-gap-baseline.md or docs/TRACEABILITY.md records the immutable artifact identity, and keep any extracted payload checksum explicitly labeled as a payload/file digest rather than the artifact digest.

#488 Validation Evidence current-authority handoff for the canonical docs lane:

  • fix(validation): preserve representable recovery metrics #488 is now exact 5d801fdb8245fb8b7a109f23553f882b1a277d75 on #492@794ba9e6dda9f043aa499920fdf609b81b075d7e, still Draft/open/mergeable.
  • The old bias_se.rs:307 four-pass correction-exhaustion state is no longer a current gap. Commit cea2d9e39b87644263bba29be2c524caea3e943d factors exact square/midpoint correction; current head binds the repository-owned <3 adjacent binary64 seed-distance theorem to exactly three fixed idempotent corrections. The old terminal None is removed causally, not suppressed/excluded/made unbounded.
  • Documentation Quality 34561110973 and Bias SE Exact-Proof Budget 34561110902 are GREEN. Rust Foundation 34561110942 is RED only at Production line and branch coverage job 103143853300; format/Clippy/no-retry tests/doctests/rustdoc/dependency policy, repository/Python+SBOM/provenance, and Live PostgreSQL are GREEN.
  • Current line artifact 10184390817, GitHub Actions archive digest sha256:88f9810169e7f23c9698f43d427928297f2e3a83f8bee3b3fe8224e976781b6e: checked-in authored-line classification is 12,344/12,346. Only crates/validation_core/src/bias.rs:69 and :592 are zero-count authored production lines. Do not retain predecessor 12,341/12,344 or bias_se.rs:307 as current debt.
  • Current branch artifact 10184423165, archive digest sha256:393ecb5e2dd69fd669d5cb52152a94ae323cc1d87d88c23b70ef839975adc50f: checked-in unique-source/per-arm-max fold is 4,450/4,452. Missing outcomes remain only bias.rs (68,8)-(68,29) TRUE and bias.rs (591,8)-(591,35) TRUE.
  • bias.rs:68-69 remains source-domain reachable through the resource-extreme n=2^54 subnormal construction, so preserve it and treat the acceptance gap as bounded representation/resource admission rather than an unreachable-branch cleanup.
  • bias.rs:591-592 remains a genuine proof/counterexample obligation: no valid compressed counterexample and no complete supported-domain unreachability proof yet. Preserve the fail-closed guard.

Please update docs/product-technical-gap-baseline.md and docs/TRACEABILITY.md on this canonical single-writer lane to replace the predecessor #488 head/artifacts/three-line state. Historical predecessor evidence can remain explicitly historical.

#488 authority handoff: Validation Evidence advanced by ordinary documentation-only commit 252831bfaad2c7dc5abf207461ffcdc4c35e3cc5, adding docs/research/validation-bias-production-resource-admission.md.

Canonical docs should distinguish the existing Analysis Run product cap from the public numerical library domain: analysis_engine::MAX_EVIDENCE_UNITS = 100_000, with AnalysisCorpus::new refusing larger in-memory corpora, is owner-correct application resource policy. There is not yet a typed/versioned trace proving every supported product bias_standard_error call passes that admission, so do not copy 100_000 into validation_core or call either remaining branch unreachable.

The known bias.rs:68-69 source-domain witness remains real at n=2^54; two public f64 slices alone require 2^58 bytes = 256 PiB, so giant materialization is not realistic buyer acceptance. bias.rs:591-592 still needs an implementation-matched floating forward-error proof or compact caller-valid counterexample; exact-real D >= n/2 is unchanged.

#488/#491 bodies now point to 252831b.... Fresh exact-head workflows are running; predecessor 12,344/12,346 authored-line and 4,450/4,452 branch artifacts remain lineage/expected production-equivalent frontier only until new immutable artifacts are terminal. Please update docs/product-technical-gap-baseline.md / docs/TRACEABILITY.md through this #435 single-writer lane rather than treating predecessor head 3b5d07b... as current authority.

Exact-head correction to the preceding #488 handoff: 252831b... added the resource-admission note, and ordinary child ef48e1c9314b1e6978e7cea16011e8515d12af6f only adds the missing terminal newline. #488 and #491 current authority now point to ef48e1c...; use that head for docs/TRACEABILITY.

#488 current-authority handoff: exact head advanced by ordinary documentation-only commit 520df488fd86ba48008af8ee5a2e112b4587fc22.

New finding is semantic/cardinality, not arithmetic. analysis_engine::MAX_EVIDENCE_UNITS = 100_000 bounds AnalysisCorpus, but analysis_engine currently has no validation_core dependency and AnalysisEvidenceUnit carries evidence identity/time/membership metadata rather than a truth/recovered numerical pair. Therefore evidence-unit count is not presently a proven bound on the n consumed by validation_core::bias_standard_error.

Canonical docs/product-technical-gap-baseline.md / docs/TRACEABILITY.md should record the missing typed/versioned buyer-path cardinality contract: before the Analysis Run cap can narrow bias-SE resource or forward-error evidence, the product path must prove how admitted evidence units map to validation truth/recovered pairs. Do not copy 100_000 into Validation Evidence or describe either remaining branch as unreachable on that basis.

The n=2^54 false-zero witness remains source-domain real. 2^54 / 100_000 is scale context only, not admission proof; independent materialization evidence remains two public f64 slices = 2^58 bytes = 256 PiB. The translated-dispersion exact-real D >= n/2 theorem is unchanged; floating positivity still needs implementation-matched proof or a compact counterexample.

#488/#491 current authority now points to 520df488.... Fresh exact-head CI/review must replace predecessor evidence before any landing claim.

#488 exact-current handoff for the canonical docs lane:

  • Validation Evidence head is now 520df488fd86ba48008af8ee5a2e112b4587fc22 on prerequisite #492@794ba9e6dda9f043aa499920fdf609b81b075d7e; this head is documentation-only relative to 3b5d07b2e438edef9c529317d9dd09bd53451a92 and changes only docs/research/validation-bias-production-resource-admission.md.
  • Exact-head Documentation Quality 34573224170 and Bias SE Exact-Proof Budget 34573224257 are GREEN. Rust Foundation 34573224268 is RED only in Production line/branch coverage job 103179819615; Live PostgreSQL 103179819441, Rust quality 103179819679, and repository/Python contracts + SBOM/provenance 103179819783 are GREEN.
  • Current line artifact 10188730908, GitHub Actions archive digest sha256:f6c560819690274ad205baf77ec46089835d5563e7bbcb3d2f941fb532e63ff0. Its LCOV has the same 42,005 source/line DA keys and same two zero-count records (bias.rs:69, bias.rs:592) as predecessor 3b5d07b...; authored production authority remains 12,344/12,346 because the delta is documentation-only and classifier inputs are unchanged.
  • Current branch artifact 10188776666, archive digest sha256:34006fb155957e34a86385cd9975340fa24bdb1950874c07e9d001e0070a1088. Checked-in unique-site/per-arm-max fold remains 4,450/4,452, missing only TRUE arms bias.rs (68,8)-(68,29) (0,12) and (591,8)-(591,35) (0,32). Unique source-site and covered/missing arm status match predecessor; only execution counts changed at already-covered sites.
  • The new resource-admission note explicitly rejects treating analysis_engine::MAX_EVIDENCE_UNITS = 100_000 as a bias-SE sample cap: analysis_engine currently has no validation_core dependency and AnalysisEvidenceUnit is evidence metadata, not a truth/recovered pair. Product acceptance needs a typed/versioned evidence-to-metric cardinality contract before an Analysis Run population limit can narrow the numerical proof domain.
  • Exact-head CodeRabbit review was requested, but the latest attempt hit a bot rate limit; do not record a clean review or approval. Formal reviews remain historical COMMENTED; unresolved inline review threads are zero.

Please update docs/product-technical-gap-baseline.md / docs/TRACEABILITY.md current-state sections from predecessor 3b5d07b... to this exact evidence when this lane next writes. Do not replace the public-library source domain with the application evidence cap.

Current queue authority was refreshed to #488 exact 520df488fd86ba48008af8ee5a2e112b4587fc22, its exact-head artifacts/digests, the completed CodeRabbit no-findings review, and the Analysis Run evidence-count vs Validation Evidence metric-cardinality boundary. This metadata repair does not claim the checked-in docs/product-technical-gap-baseline.md / docs/TRACEABILITY.md files are already current. The #435 canonical docs writer still needs to carry the same exact evidence into those files by ordinary forward commit, preserving this branch's single-writer boundary and reacquiring exact-head checks afterward.

Queue-authority handoff: #310 is currently Draft at exact f1d02508c7b92aaaedd7e6a08083707d4ed90094 with an intentional scientific RED in mixed_sign_mean_rounding_contract::half_ulp_tail_changes_the_final_mixed_sign_rounding. The compact finite n=3 case returns 0x4680000000000000 while correctly-rounded mean authority is 0x467fffffffffffff.

Reusable repair ownership is now explicit at ContextualWisdomLab/fast-mlsirm#1814. Fresh owner inventory also found private CPython-style partials/final half-even summation lineage on open fast-mlsirm #1536 (03d1e943..., commit 5b856206...), but it is mutable, domain-private, sum-only and not sufficient/released for TEPP consumption. Canonical docs should represent #310 as blocked on an immutable fast-mlsirm finite-sum/mean Published Language rather than suggesting a TEPP-local special-case repair. Do not transfer #1536 checks/source as dependency evidence.
