Performance-improvement review corpus
**Current scope freeze:** [485-PR index and policy](mining/README.md), [exposure ledger](mining/evaluation/exposure.json), and [evaluation protocol](mining/evaluation/protocol.json). Historical sections below are preserved; previous holdout labels do not establish freshness. Real-source availability gaps block evaluation acceptance, not inventory accounting.Snapshot and scope
This is an acquisition record, not a reviewer, evidence-derived rules, or a review checklist. It preserves candidate selection, source provenance, historical revisions and an untouched family-level evaluation reserve.
The original inventory/split tables below are the pre-drafting snapshot. Current reconciled status is in final source-coverage accounting and effective applicability coverage; acquisition history remains in the reserved-source study. Historical "untouched" and "not evaluated" statements describe that earlier freeze, not the later execution status. Source-attribution corrections are in the named conversation audit; no original-user authorship attestation is claimed.

Unit of evidence |
PR, nested within a mechanism family. Multiple comments/reviews/revisions do not create independent PR votes. |
All results of both primary-author searches were screened, including complete descriptions, not just titles or labels. Other authors were discovered by the union of live performance-related labels, title/body terms and relevant local links. Open, draft, merged and closed-unmerged states were retained. A nonempty performance claim, measurement, or concrete performance-oriented mechanism in the title, label or description qualifies; a template's unchecked benchmark checkbox does not. Linked versions stay together even when one version has no independent performance claim. Correctness-only optimizer/cache changes remain excluded rather than inheriting eligibility from their vocabulary.
Created-in-window PRs qualify temporally by creation. Older candidates require a timestamped event in the window; updatedAt alone is not proof. Earlier descriptions, commits and discussions are explicitly context, not newly created in-window evidence. Retrieval-time states, labels, descriptions and thread resolution are snapshots: GitHub does not provide an immutable history of every edit, deletion or resolution transition. The cutoff bounds evidence, not the time an API request ran.
Role boundaries were read at the checkout revision: .github\agents\extraction-pipeline.md supplies collection-channel and PR-normalization concepts, not generated review rules; .github\agents\expert-reviewer.md describes the general correctness reviewer; .github\agents\compiler-perf-investigator.md describes measurement/investigation. None is human-review evidence. tests\benchmarks\README.md distinguishes compiler/FCS/IDE performance from generated-program performance and warns against comparing different machines/environments. No builds, benchmarks or compiler tests were run for this documentation-only sprint.
Discovery ledger
The exact queries and their observed totals are below. Every search used:
gh api --method GET search/issues -f "q=$query" -f per_page=100 --paginate --slurp
Labels were enumerated with both gh label list --repo dotnet/fsharp --limit 300 --json name and gh api --paginate --slurp 'repos/dotnet/fsharp/labels?per_page=100'. Live label-name screening included performance, optimization, memory, allocation, latency and throughput. Only Area-Compiler-Optimization, Performance and Theme-Performance matched those names. A zero-result label query is an observed zero, not an omitted channel. Search results were all below the 1,000-result cap; no date subdivision was needed. All pages reported incomplete_results=false.

141 labels in 2 exhausted REST pages. Search union: 1,205 result occurrences, 475 unique PRs, 730 duplicate occurrences. Linked expansion adds 10 PRs, giving 485 inventory rows. Q01/Q02 contain 270/293 unique PRs (250/260 actual T-Gro plus 20/33 Copilot); Q03/Q04 contain 52/57 auduchinok PRs. The created sets are subsets of the activity sets: 350 distinct primary-query results, each reconciled to one inventory row. No result was discarded because the returned author differed from the search author.
The author:T-Gro queries also returned PRs whose actual author is Copilot. Their author identity is preserved; they are not silently recast as T-Gro-authored human material. Supplemental term searches included singular/plural and US/UK variants. Full-body screening excluded boilerplate, dependency names and incidental terminology, with explicit reasons in the inventory. In particular PR-19689 and PR-19703 survived body-only selection.
Relevant linked PRs were expanded from candidate descriptions; issue links were resolved as issues rather than invented PRs. Link expansion and the older-active event checks are recorded below. No holdout discussion body was fetched to decide a split.

Older-candidate activity audit (metadata only; final cursor exhausted for every row). Counts cover direct comment/review, code, label and lifecycle events exposed by the recorded fragments. Incidental cross-references/project-board moves are not treated as performance-relevant activity. Earlier timestamps are retained separately.

Candidate inventory
Each repository/PR number occurs once. development and holdout are evidence partitions; control is the non-performance partition. Excluded rows in development/holdout are linked context belonging to that family, not extra evidence. Only the explicitly reserved applicability controls in the holdout section are evaluation cases; the other excluded control rows are the screening audit.
Dates are UTC. C/U means created/updated; close/merge preserves both timestamps (a dash means absent). State is merged, closed without merge, or open, with draft status shown separately. L/T/B identify label/title/body selection, and linked means family/context expansion. Selection and state do not assert acceptance, rejection or measured effectiveness.

Family splits and untouched reservations
2026-09-22 RED-stage correction: an architect seed exposed PR-20348's review exchange; this was not an original-user authorship attestation. Before mining it, all six members of FAMILY-self-profile (20348/20349/20350/20351/20353/20354) were moved from holdout to development. Their acquisition supplement appears below. The original acquisition counts elsewhere remain historical, not current split totals: there were then 40 included development and 82 included holdout PRs, plus unchanged context/control rows; the reservation table has 94 rows. At that freeze FAMILY-compiler-parallel, including PR-18998, remained an untouched evaluation reserve; no replacement family was mined. Neither this exposed family nor any paired historical/final versions may be used as holdouts.
The first split used only descriptions, changed-file metadata and explicit stack/supersession links. It reserved the interconnected closure/inlining, editor-work-reuse, hot-reload and generated-program families, plus non-performance boundary controls. Development contains separately selected cache, pattern-memo, fusion and build-latency families. This is deliberately not a random sample or an estimate of review-outcome prevalence.
One conservative contamination correction was required: PR-20088 author comment 5109201253 explicitly linked its savings to PR-20090. The whole IL-import-retention family was therefore moved into development before its feedback was inspected. It is not an untouched holdout. PR-20352 and PR-20363 stay together as FAMILY-inline-copy; PR-20373/20384 stay together with their shared ListInline/closure family. PR-20425 is also in that closure family, not the development tree-copy family. Editor stacks and alternate versions are reserved together even when that makes the reserve large.
Only metadata, pinned retrieval pointers and change-type coverage appear in the following reserve. No holdout objections, expected review outcomes or evidence-derived rules are published. Public PR descriptions were necessarily screened; human review/comment bodies were not mined for reserved families. The complete five-month study is not claimed complete: these reserved sources have not been evaluated.

Benchmark-only gap: no benchmark-only PR was found in the exhausted benchmark/benchmarks title/body searches, their union with all other queries, or changed-file metadata for the entire inventory. PR-18509 combines benchmarks with product code; PR-20092 combines namespace-import benchmarks with compiler changes. Neither is relabeled benchmark-only. Test-only controls PR-19676/20444 and docs-only control PR-20436 are real no-performance-claim cases. Auduchinok's untouched reserve is explicitly test/API applicability controls, including the recent rich-text family PR-20507/20552/20556; the promoted IL-import performance family is not falsely advertised as unseen. This acquisition does not manufacture the missing category or widen the date window.
Development source completeness
For every included development PR, the pull metadata, all files/reviews/issue-comment/inline-comment/timeline/commit pages, GraphQL review threads and all nested thread-comment pages, and patch output were acquired. Empty-body approvals and comment-only reviews are retained. Review dismissals are read from timeline events, not inferred from the current aggregate decision. Resolved and outdated threads are included.
files reconciles pull metadata, file pages and pinned Git diff paths. R/I/C/T are submitted reviews, issue comments, unique inline comments and threads. Inline comments returned by REST and GraphQL are deduplicated by stable node/database ID, not by text. Page counts include a fetched empty page for an observed zero; exhausted GraphQL cursors mean hasNextPage=false, not a guessed count. Git diffs use the pinned merge base and head, never today's main. Full files at both ends and adjacent signatures were retained as session artifacts; context coverage and additional pinned callers/tests are described per PR.

For every row: outer and nested thread cursors, review-metadata cursors and unfiltered timeline cursors exhausted. REST inline IDs equal GraphQL inline IDs exactly. Submitted commit totals match pull metadata. The filtered dismissal/deletion GraphQL connection reports the unfiltered timeline totalCount. Raw unfiltered node counts also differ from that total: in every development PR, the observed identity is totalCount = returned nodes - MentionedEvent - SubscribedEvent + separately fetched reviews - returned PullRequestReview nodes. The independent reviews connection retains the individual reviews omitted/collapsed in timeline display. This identity was checked for all 34 PRs; neither total was silently equated to node count. Local filtering and the filtered connection both returned zero dismissal/deletion events for all development PRs. A deleted event/body elsewhere is not ruled out by this observation.
Provenance notation
- author rationale: PR author account describing intent, measurements or responses; not independent review evidence.
- user-account feedback/decision: a non-bot account in reviewer/discussion role.
Userand membership are identity metadata, not proof the text was human-written. - automated/model-attributed: GitHub bot account, explicit AI attribution, or a source's explicit automation disclosure. Replies do not turn the preceding model text into human precedent.
- uncertain: quoted text with unknown origin or otherwise unestablished authorship. No classification is based on writing style.
Measurements below are faithful source snapshots, not reproduced benchmark results. Empty approvals have no invented rationale. Source rows preserve author association, timestamps, revision and retrieval channel; inline rows distinguish the original commented-on revision from the currently mapped revision. General issue comments have no commit binding in the API: a missing revision is explicitly unbound, not an assertion that the comment discusses the final head. Description hashes identify the exact acquired API body encoded as UTF-8, without line-ending normalization, but cannot recover deleted earlier edits. Diff hashes use UTF-8 text normalized to LF line endings.

WIF credential migration preceding PR-19703; retained as the same revision family, not an independent performance claim.
Diff and surrounding context: The one-file insertion-pipeline diff replaces the PAT variable group with an AzureCLI token acquisition step feeding the existing MicroBuild insertion task. PR-19703 adds the credential-helper change. No compiler signature or test changes.
Pinned head files/signatures acquired: eng/release/insert-into-vs.yml.
Source gaps/qualifications: Private dnceng work-item and service-connection state are not public evidence; no insertion run or timing was independently reproduced.

Centralizes CE builder-method lookup in a per-computation-expression dictionary and adds missing-member diagnostic tests; the body supplies the cache claim although the title and labels do not. Published build/test logs are author assertions, not performance measurements.
Diff and surrounding context: Full two-file diff changes lookup from AtMostOneResult to AllResults, adds tryFindBuilderMethod to ComputationExpressionContext and routes Source/Quote/Yield/Combine/Delay presence checks through it. Historical CheckComputationExpressions call sites and its TryFindIntrinsicOrExtensionMethInfo wrapper over AllMethInfosOfTypeInScope were inspected. Two new component tests assert FS0708 for missing Return/Delay. No signature changes.
Pinned head files/signatures acquired: src/Compiler/Checking/Expressions/CheckComputationExpressions.fs, src/Compiler/Checking/Expressions/CheckComputationExpressions.fsi, tests/FSharp.Compiler.ComponentTests/Conformance/Expressions/ComputationExpressions/ComputationExpressions.fs.
Source gaps/qualifications: No human review or explanation of closure was returned; closed-unmerged is not classified as rejection.; The description says Closes #36; the local issue is unrelated, so that link is not adopted as rationale.

Reapplies the WIF insertion migration and disables GCM for the insertion step; describes an approximately eight-minute clone delay from oversized Entra credentials. This is build-pipeline latency, not compiler or generated-program speed.
Diff and surrounding context: Full one-file diff and the historical insertion-task inputs/conditions connect the AzureCLI secret variable to MicroBuildInsertVsPayload; the GCM step uses the same branch condition. PR-19683 is the preceding version. No compiler/test changes.
Pinned head files/signatures acquired: eng/release/insert-into-vs.yml.
Source gaps/qualifications: Private dnceng work-item and service-connection permissions are not acquired; claimed insertion latency is not independently reproducible from public source alone.

Reports Debug per-edit checks growing from 945 ms to 7758 ms with 16,338 leaked listeners, and a flat loop after removal. The description still describes direct per-cache Stats at acquisition, whereas final code uses shared name-aggregated Stats; preserve this revision mismatch rather than silently rewriting the author's account.
Diff and surrounding context: Entire eight-file diff inspected: removes per-cache listener and cacheId, uses existing ListenToAll/getStatsByName, removes internal checker helper and public listener surface, updates Caches.fsi/service.fsi and surface baseline, and changes cache/overload tests to name totals and deltas. Historical listener lifecycle/callers and all original review hunks inspected. Comments at f96b70e1 discuss the earlier per-cache Stats proposal; comments at 1c1f7a9f discuss name aggregation and serialized tests. Final approval is at bd2148ba.

Source gaps/qualifications: Heap dump and raw timing runs were not attached in the acquired description; numbers remain author-reported.; Description/final-diff mismatch is material and explicitly retained.

Removes per-instance synchronization objects from InterruptibleLazy and DelayInitArrayMap, acknowledging locking-on-this risk. Author comment 5109201253 states its savings overlap PR-20090 and do not add; this caused the entire IL-import family to be promoted to development before reading that family's feedback.
Diff and surrounding context: Full three-file diff inspected with illib implementation and signature: Monitor.Enter/Exit moves to this, the separate field disappears, and InterruptibleLazy gets a do-not-lock documentation warning. Historical ILMethodDefs/ILTypeDefs subclasses and use sites inspected; no test changes. Original review revision bdb5b043 and later approved eed9571a/94167098 objects recovered.

Source gaps/qualifications: Review 4847726827 explicitly attributes itself to AI expert-reviewer; its inline comment 3706983749 is model-attributed despite T-Gro's User account.; The quoted measurement account in author comment 5109201253 has uncertain original authorship, not independently established human precedent.

Author says the trait-source walk eagerly imports all namespaces of non-F# references even though their value lists cannot supply F# trait constraints. Skipping those CCUs reportedly reduces retained memory 27.8% on a 486-reference project and 10.2% on a console project; FCS itself is within noise. The detailed description explicitly identifies itself as AI-generated.
Diff and surrounding context: Final 2-path/29-line diff adds an IsFSharp guard around the existing constraint-source traversal and a release note. Historical context reads the complete traversal, IL namespace/type import producing empty value lists and CcuThunk.IsFSharp. No test or signature change in this diff; related member-constraint fixture and the separate namespace tests in assigned #20092 provide context, not a claimed validation run.

Groups lazy type definitions into lazy namespaces, including custom Rider readers, and adds laziness tests. Description explicitly combines measurements with #20088 and #20090: console retained memory 77.7 to 59.9 MB and FSharp.Common 1319.2 to 766.0 MB; FCS retention is noise. Separate read-count, warm-time and allocation tables are source claims, not isolated effects of this PR.
Diff and surrounding context: Final 18-path/2510-line diff introduces independent lazy namespace/types realization, ILPreNamespace abstract class, deferred type-name indices and DelayInitValue; changes grouping/lookup/flattening, import granularity, nullness fallback closures, no-typar singleton, name/AutoOpen forcing and empty QueueLists. Static linking restores metadata-index order; generated flat tables retain order. il.fsi/illib.fsi and service surface baseline change. Reads full cancellation/order and 676-line namespace tests, 454-line benchmark/probe source plus project/README wiring; emitter consumers and original guard inline are pinned. Initial guard overlap with #20090 is absent from final diff after rebasing.

Removes hard overrides of MSBuild node reuse on both platforms, restoring Arcade's local/CI defaults and enabling MSBuild Server. Body explicitly identifies a historical bootstrap assembly-version-conflict risk rather than claiming it was disproved.
Diff and surrounding context: Entire five-line deletion across Build.ps1/build.sh inspected with pinned eng/common/tools.ps1/tools.sh defaults and EndToEndBuildTests wiring. No tests/signatures changed. Linked issue 20217 supplies the original inner-loop claim; historical script comments identify the bootstrap reason.
Pinned head files/signatures acquired: eng/Build.ps1, eng/build.sh.
Source gaps/qualifications: No timing data or independent bootstrap validation executed in this acquisition sprint; two empty approvals are decisions, not performance arguments.

Diff and surrounding context: Entire eight-file diff inspected, including diagnostic and compilation paths, thunk lifting/clone guards, CompilePattern's new bindings result, CheckExpressionsOps caller, .fsi, quotation assertions, runtime/byref/rethrow tests, project inclusion, and pinned downstream regression repository. The original review at 6eb4cae7 concerns conditional CloneAll, not the final unconditional clone. Structural-key successor PR-20337 stays in this family.

Description consists of retained-memory measurements: realizing all type definitions across 181 runtime assemblies falls 28.4 to 17.3 MB; console and FSharp.Common fall 5.5% and 5.2%; FCS falls 0.1%. Title identifies reuse of empty member tables.
Diff and surrounding context: Final 2-path/260-line diff probes EventMap/PropertyMap/MethodImpl row ranges while realizing the type, returns existing empty field/method/event/property/implementation tables when absent, and defers nonempty reads while reacquiring metadata views. Reads row-range helper, all empty-table definitions and signatures; typeDefReader callers are in diff. Release note included; no tests added.

Author identifies a metadata view captured by the interface-implementation lazy, defeating WeakByteFile for stable non-framework references. Reports retained-memory changes ranging from negligible framework-only projects to 33.1% on FSharp.Common, alongside reference counts and weak-versus-strong bytes.
Diff and surrounding context: Final 4-path/122-line diff moves mdfile.GetView inside the interface-implementation lazy and removes its mdv argument/call-site capture. Adds an object-graph retention test over stable-package metadata with unforced lazy members and service project wiring. Reads WeakByteFile, BinaryFile ownership and filesystem-shim contract; ilread.fsi snapshot preserved unchanged.

Adds ILCallingConv.Create backed by all 18 convention combinations. Author's heap snapshot reports 60,239 live convention objects becoming 18, with project retained-memory changes of 0.08–0.55%.
Diff and surrounding context: Final 11-path/294-line diff builds 18 calling-convention singletons, exposes Create/member access and privatizes the union in il.fsi. Migrates reader, parser, printer, reflector, writer and pickle construction/matches; service surface baseline reflects removed union access and added factory/properties. Cancellation-test constructor adapted; no identity assertion added. Reads calling-convention and pickle-tag contexts. Final stride remains literal 6; release-note placement/link changes retained.

Reuses Entity.CompiledRepresentationForNamedType instead of rebuilding the same ILTypeRef per ILTypeInfo, in tuple and ordinary IL-application branches. Author reports 150,928 to 53,262 ILTypeRef objects and 5.07 MB less retention on FSharp.Common.
Diff and surrounding context: Final 2-path/42-line diff obtains cached named ILTypeRef in the tuple and isILAppTy branches, keeps the ILTypeDef and adds a release note/newline. Reads cached Entity.CompiledRepresentation, its TILObjectRepr branch, FromType/CreateILMeth and infos.fsi. No added test or signature edit.

Diff and surrounding context: Final 7-path/197-line diff separates unprioritized extension-shape computation from per-open priority; caches imported-class results by stamp on CCU, leaves local classes uncached, skips caching observed import failure, and stores shapes as obj due declaration ordering. All four CcuData creation routes and TypedTree.fsi updated. Reads AddStaticPartsOfTyconRefToNameEnv fold and extension fixtures; no test edit. Release note included.

Caches TypeDef-row-to-ILTypeRef results per metadata reader, including nested enclosing chains, rather than rereading immutable metadata. Author attributes 30% of type-name reads to the old path and reports 2.08 MB and 1.88 MB retention reductions on FSharp.Common and FCS.
Diff and surrounding context: Final 2-path/53-line diff adds reader-held seekReadTypeDefAsTypeRef and uncached worker, wraps it in an always-enabled zero-capacity initial cache and retains recursive cached enclosing-type lookup. Reads full nested-row worker and mkCacheGeneric, including reduce-memory bypass distinction. Release note; no added tests/signature edits.

Changes the string-heap cache to grow from zero and removes the computed type-name intern table, whose fixed buckets cost more than duplicate strings saved. Reports 1.5–10.1 MB retention reductions, noise-level time changes and approximately 0.24 MB of remaining duplicates; Tables.memoize remains for ilmorph.
Diff and surrounding context: Final 2-path/62-line diff removes memoizeString state/initialization, concatenates names directly and changes cacheStringHeap initial capacity from stream-derived to zero. Reads ILTypeRef value comparison, Tables.memoize's fixed 1000 capacity and surviving ilmorph caller. Release note; no added tests/signature edits.

Review says removing computed-name interning preserves value equality and cached/one-shot callers, validates zero initial capacity and retained-memory tradeoff, and asks only for release-note link. Sprint-10 envelope audit found no explicit automation disclosure for this review; the earlier model-associated classification is unsupported, not inferred from prose style. Separate tooling bots below do not establish this review's composition. |

Describes replacing stored entity public paths with struct views over compilation path plus name and value-option accessors, while keeping the pickle format. The description discusses custom equality and EqualsFullPath from an earlier version. Reports 2.68 MB less retained memory on one FSharp.Common project and 20.69 MB on ReSharper solution.
Diff and surrounding context: Final 13-path/629-line diff removes entity_pubpath, derives struct PublicPath/voption, adapts constructors/linking, symbol/tooltip/provided-type/overload consumers and pickle path read/write. Final PublicPath is NoEquality; short-circuit pubPathEq is a function over access-path names, while fslibRefEq allocates FullPath. This differs from description/early reviewed CustomEquality/EqualsFullPath version; both original versions inspected. Internal .fsi updated; no test files changed.

Makes the ad-hoc member ResizeArray and compiled-representation cache lazy, retaining member-level interfaces. Reports 1.32 MB less retention on FSharp.Common, with heap counts indicating 95% unused ad-hoc lists and 89% unused cache cells; provides project and whole-solution measurements with noise qualifications.
Diff and surrounding context: Final 6-path/220-line diff adds nullable ad-hoc member storage with AddAdhocMember/AdhocMembers, adapts the publisher/pickler/remapper, and lazily creates entity compiled-representation cache cells at access. Nullable fields and helper declarations updated in .fsi. Unpickling still calls newCache, as the review notes. Reads NewILTycon and actual cached CompiledRepresentation consumer; no tests changed.

Replaces Reader/Given union wrappers in ILAttributesStored with reader and nullable-array fields. Author reports 78% of attribute owners were never forced, predicts approximately 1.34 MB net savings and measures 1.32 MB on FSharp.Common; preserves volatile publication and the public factory/member signatures.
Diff and surrounding context: Final 2-path/73-line diff deletes internal Reader/Given representation and keeps shared reader plus volatile nullable array; CreateGiven retains a noReader sentinel and CustomAttrs wraps cached arrays as a struct. Reads factories, attribute-row reader, public il.fsi contract and original closure discussion location. Release note; no tests or signature edits.

Shares imported binary assembly CCUs across projects using file/closure/configuration keys, weak entries and closure-pinned import contexts. Excludes project outputs, type providers, multi-module and unaccounted closures. Describes removing four project TcImports captures; reports 545 MB retention and 8.9% warm-time savings on ReSharper, much smaller effects elsewhere.
Diff and surrounding context: Final 14-path/1128-line diff adds typed import-reuse settings, closure/file/framework-stamp keys, weak shared CCUs, pinned import contexts, delayed publication, binary/F# import hit/miss handling and exclusions. Threads shareImportedAssemblies through both compiler modes and makes it default true; ClearCaches clears it. CompilerConfig/Imports/service signatures and surface baseline change. Original string-key/default-false/config inline contexts and adjacent framework cache/multiproject symbol tests inspected. No behavioral test added by this diff.

Groups C#-style extension methods by static class, open priority and extended type, sharing cached method lists and deduplicating individual candidates. Author reports 95,408 wrappers for 9,741 methods before grouping, 6.12 methods per group, and 5.64 MB less retained memory on FSharp.Common; claims candidate order unchanged.
Diff and surrounding context: Final 3-path/184-line diff changes ILExtMem to MethInfo list, groups shape by extended-type stamp plus unindexed group, reverses each group to preserve fold order, caches grouped lists and deduplicates candidates by method definition. NameResolution.fsi and release note change. Reads candidate hierarchy/selection callers and existing extension fixture; no new tests.

Description: ID PR_kwDOAbtAO88AAAABAUFgsw (REST pull ID 4316029107), auduchinok/User, author role, text origin uncertain, association MEMBER; PR created 2026-08-19T17:22:19Z, updated 2026-09-01T12:36:31Z; body lastEditedAt null. Captured 2026-09-22T09:38:00Z, GraphQL body identity rechecked 2026-09-22T10:00:39Z. Body SHA-256 ae947d2d038c1e4e2d2af2a71671429c6dcfbc8822ad8b1b85881d426d68b184.
Interns IL scope, type and method references within each unpickled blob without changing the format. Description reports enormous per-blob repetition (FCS scopes 55,721 reads for two values) and whole-solution retention savings of 63.9 MB on ReSharper and 21 MB on Fantomas, using netstandard2.0-compatible dictionaries.
Diff and surrounding context: Final 2-path/88-line diff adds three ReaderState dictionaries, initializes both states and interns after scope rescoping and type/method construction. Reads ILTypeRef key/cache implementation, eager u_lazy behavior, type-reader callers and abstract ReaderState signature. Release note; no behavioral tests added.

Replaces PR-20244's stringified memo key with typed structural keys; adds declaring-type stamps, explicit join-promotion mode and a code-size guard. Body reports equal sizes and IL fingerprints at N=8/16/24/32/40, not a new measured speedup.
Diff and surrounding context: Entire two-file diff inspected with pathEq and CompilePatternBasic callers. New PathKey/BoundExprKey/FrontierKey/MemoKey shapes, MemoEntry lazies and JoinPromotion replace textual keys/tuple state. The 32-disjunct test asserts a sub-1,000,000-byte image. Same pattern-memo family, not an independent example.

Proposes fusing copyExpr and remarkExpr; reports approximately 321 MB saved per 65,880-LOC compile and unchanged IL/PDBs. Author issue comment 5422336205 explicitly closes it as too bloated for the win and says it will be reworked; withdrawal is supported by that comment, not inferred from closure.
Diff and surrounding context: Entire 427-line, three-file diff inspected: two optimizer call sites plus pervasive optional range/debug-point handling in the existing remapper, its new context field and exported signature. Pinned standalone remarkExpr/remarkBind and CopyExprForInlining behavior inspected for ranges, debug-point erasure, cloned locals and quotation handling. No test files added; all benchmark/differential assertions are in the description.

Fuses generic inlining copy with type instantiation for a saturated TyLambda, leaving the non-generic path unchanged. Reports 10,662 to 10,105 MB per compile, three runs times four iterations, and IL/PDB comparisons with a reflected-definition resource-name caveat.
Diff and surrounding context: Full two-file diff inspected: two unified-diff hunks in one localized Optimizer function, plus release note. The description calls this one hunk; source verification corrects that code fact without changing the captured description. Historical CopyExprForInlining, remapExpr/mkInstRemap, instType and MakeApplicationAndBetaReduce establish which traversal is removed. No test changes. Reserved in the same development family as PR-20352 despite its different fusion target; one empty approval retained.

Shares one EntityRef wrapper and resolution cache per nonlocal reference-table row via a ReaderState array. Reports 88,642 wrappers for 1,919 rows before the change, modest project/solution retention gains, matching diagnostic counts and noise-level time differences. Explicitly says the test suite was not run.
Diff and surrounding context: Final 1-path/55-line diff adds ReaderState.itcrefs, allocates by nonlocal-table row count and reuses ERefNonLocal wrappers after bounded table lookup; local references unchanged. Reads EntityRef binding/dereference and decode/lookup helpers plus adjacent pickle signature. No tests/signature/release-note change; bot records release-note opt-out.

Restores the debuginfo condition for FSI multiemit PDB emission. Refers to a downstream reported 5-10x debugger-dependent reload multiplier and explicitly supplies artifact tests instead of a timing benchmark.
Diff and surrounding context: Full three-file diff inspected including release-note cleanup, FsiDynamicCompiler PDB option and paired debug-on/off PDB-artifact tests. Historical WriteILBinaryInMemory and Assembly.Load overload selection inspected; PR-14537 and issue 17306 plus bryanedds/Nu issue 1090 are earlier rationale, not new in-window measurements.

Offers a remapped/pruned project CCU to consumers instead of always pickling/unpickling, depending on #20296. Describes rebinding consumer dependencies, up to eight reusable bound copies and earlier binding before relink, plus builder-race repair. Reports 81.3 MB ReSharper and 74.63 MB Fantomas retention savings; explicitly separates the larger FCS improvement from language-version-key removal. Description's missing-name producer fallback describes an older version.
Diff and surrounding context: Final 19-path/2417-line diff adds project-CCU handover, lazy signature bytes, dependency rebinding/copy matching/cap, claim-based shared publication, deterministic binding before relink, export accessibility/scope remap, trait-context clearing, anonymous-record owner rebinding and explicit-interface-member filtering. ImportsNullness replaces version/null flag keys; WithLanguageSettings copies caller nullness. Background builder double-check changes; transparent compiler explicitly supplies no handover. Internal signatures and 804-line ProjectReferenceHandoverTests cover sharing on/off, access, dependency layers/chains/diamonds, concurrent consumers, surface/docs and reported regression cases. Original six AI inline contexts and IVT consumer path inspected. No builds run.

Fixes state-read/update, invalidated-builder replacement and concurrent parse races. Description reports a 50-request stress case checking each file ten times before and once after. Final implementation additionally separates completed weakly retained parse results from in-flight graph nodes.
Diff and surrounding context: Final 5-path/328-line diff moves state read/update under semaphore, compares observed builder nodes under gate, locks builder lookups and separates completed parse-result MRU from in-flight GraphNode MRU. Adds 50-concurrent-check stress fixture and retained-result-after-GC fixture with project wiring/release note. Original weak GraphNode cache from review SHA inspected; BuildGraph/retention consumer context retained.

Interns metadata attributes, constructors and type references across readers in three bounded clearable tables. Gives repeated/distinct value counts, hashing-cost rationale and whole-solution retention changes of about 1–7 MB. Description presents constructor-row caching as avoiding repeated hashes.
Diff and surrounding context: Final 2-path/175-line diff adds bounded concurrent InternTables (attributes/type refs 8192, constructors 2048), constructor-identity attribute comparer with blob-prefix hash, interning at metadata read sites, cached constructor read and clearing hooks. Reads mutable Encoded byte[] public contract, ClearCaches caller and attribute-emission context; original mutation report location inspected. No tests/signature edits. Author's dismissal-in-practice reply and approval suggestion remain distinct evidence, not resolved correctness claims.

Memory-maps the short-lived metadata-only PE reader used by FCS/IDE when reducing memory. Reports 306.6 MB less allocation on FSharp.Common and smaller allocation reductions elsewhere; whole-solution warm-time table includes both improvements and small slowdowns.
Diff and surrounding context: Final 3-path/114-line diff maps the temporary PE view, changes MemoryMappedStream to override Dispose(bool), and disposes the opened file stream when mapping construction throws. Reads getBinaryFile safeHolder, filesystem implementation/shim test and original failing location. Release note; no regression test added in final diff.

CheckIWSAM only needs intrinsic methods because its warning predicate rejects extension members. Description replaces AllMethInfosOfTypeInScope with the intrinsic helper and reports solution timings including 3% faster ReSharper and 7% slower console.
Diff and surrounding context: Final 3-path/48-line diff calls IntrinsicMethInfosOfType directly from CheckIWSAM with AllowMultiIntfInstantiations.Yes and IgnoreOverrides, and exposes the helper internally in NameResolution.fsi. Reads both old composing and new intrinsic helpers plus existing IWSAM/SRTP fixtures. Predicate unchanged; release note; no test edit.

Delays TyconAugmentation creation for entities, especially imported IL types that only need a closed flag. Description reports whole-solution retention changes from 0.18 MB on console to 3.24 MB on ReSharper.
Diff and surrounding context: Final 9-path/376-line diff starts augmentation null and installs one via CompareExchange, moves closed state into a nonpickled EntityFlags bit, adapts constructors/EntityRef/overrides/InfoReader, keeps null through remapping and forces TypeContents only for pickle output; unpickling sets closed bit. Internal signatures updated. Reads remap caller and pickle augmentation encoding. No tests added.

Short description says this continues #20478 and removes extra inferred-signature copying to avoid work and reuse analysis symbols. Full diff also contains the FileSignature API work from that dependency.
Diff and surrounding context: Final 16-path/774-line diff removes inferred module-type copy and post-inference prettification, bypasses identical-stamp signature remaps, threads own file signature through sequential/graph/background/transparent checking and exposes FileSignature plus surface baseline. Removes obsolete copy/finish helpers. Five Symbols.FileSignature fixtures cover file-only surface, hidden implementation/signature entities, definition stamps, background and same-file ownership. Reads Symbols.DeclaringEntity fallback and original AI report location. Diff includes #20478 API work; no outside-PR feedback fetched.

Earlier FSI symbol-to-disk change; linked by PR-20394 as the origin of unconditional PDB emission. |
PR-18930 and PR-14537 are earlier-context PRs, not in-window votes; their development-family assignments prevent reuse as holdouts. Issue 18425's 14 comment IDs are 2761948126, 2765745705, 2765816899, 2766046586, 2801893718, 2835022389, 2934231498, 2939186260, 2939191918, 2939567439, 3461664832, 3511614554, 3511751634, 3512448762. They span 2025-03-28 through 2025-11-10. Comment 3461664832 explicitly attributes its proposed implementation to Claude Sonnet; that part is model-attributed, not a human-derived rule. Comment 3512448762 values the proposed test, not a measured performance result.

Context gaps: the issue-18425 zip and screenshots and the PR-14537 screenshots were referenced but not executed or used as numerical evidence; archived API text does not contain their bytes. The public text and pinned PR diffs suffice for the source notes above, but image-only timing details are not certified. Private dnceng work item 10091 and insertion service-connection state were not acquired. No claim of complete attachment acquisition is made.
Reproduction without switching checkout
Use a fresh artifact directory for responses; do not overwrite this snapshot with current mutable bodies. Set $n to an inventory PR number. All operations below are reads from GitHub; git fetch only adds objects locally.

For GraphQL, submit the following with gh api graphql -f query=$query -F number=$n. On each outer page pass -f cursor=$endCursor until hasNextPage=false. Independently paginate each thread's comments with node(id:$threadId) { ... on PullRequestReviewThread { comments(first:100,after:$commentCursor) { ... } } }; do not assume 100 comments or one thread page is enough.
query($number:Int!, $cursor:String) {
repository(owner:"dotnet", name:"fsharp") {
pullRequest(number:$number) {
id number url author { login __typename } createdAt updatedAt
baseRefOid headRefOid changedFiles
comments { totalCount }
reviews { totalCount }
reviewThreads(first:100, after:$cursor) {
totalCount pageInfo { hasNextPage endCursor }
nodes {
id isResolved isOutdated path line originalLine startLine originalStartLine
comments(first:100) {
totalCount pageInfo { hasNextPage endCursor }
nodes {
id databaseId url body author { login __typename } authorAssociation
createdAt updatedAt path line originalLine diffHunk
commit { oid } originalCommit { oid }
pullRequestReview {
id databaseId state createdAt submittedAt updatedAt commit { oid }
}
}
}
}
}
}
}
}
Also paginate pullRequest.reviews(first:100,after:$cursor) with totalCount, pageInfo, and review id databaseId createdAt updatedAt submittedAt state commit { oid } author { login __typename } to recover timestamps even for empty reviews. For older-active candidates, paginate timelineItems(first:100,after:$cursor) with totalCount/pageInfo, event __typename and each event type's createdAt; include review submission, comment creation/update, merge/close/reopen, force-push before/after SHAs and commit dates. Do not use the latest update date as an event. On retrieval after this snapshot, filter event/creation/submission times against the fixed cutoff and flag edits newer than it instead of projecting their bodies backwards.
The exact older-activity selection was:
query($number:Int!, $cursor:String) {
repository(owner:"dotnet",name:"fsharp") {
pullRequest(number:$number) {
timelineItems(first:100,after:$cursor) {
totalCount pageInfo { hasNextPage endCursor }
nodes {
__typename
... on IssueComment { databaseId createdAt updatedAt url }
... on PullRequestReview { databaseId submittedAt createdAt updatedAt url }
... on ClosedEvent { createdAt }
... on ReopenedEvent { createdAt }
... on MergedEvent { createdAt commit { oid } }
... on HeadRefForcePushedEvent { createdAt beforeCommit { oid } afterCommit { oid } }
... on PullRequestCommit { commit { oid committedDate } }
... on LabeledEvent { createdAt label { name } }
... on UnlabeledEvent { createdAt label { name } }
... on ReviewDismissedEvent { createdAt previousReviewState }
... on ReadyForReviewEvent { createdAt }
... on ConvertToDraftEvent { createdAt }
... on RenamedTitleEvent { createdAt }
... on BaseRefChangedEvent { createdAt }
... on ReviewRequestedEvent { createdAt }
}
}
}
}
}
The metadata-only file scan used pullRequest(number:$number) { files(first:100,after:$cursor) { totalCount pageInfo { hasNextPage endCursor } nodes { path additions deletions } } }, batched by 20 PR aliases and independently paginated per PR. No file patch or review body was needed for this scan. Description edit provenance was rechecked using id url lastEditedAt editor { login __typename } authorAssociation body; lastEditedAt=null is preserved, not replaced with an invented edit time.
Development dismissal/deletion checks used timelineItems(first:100,after:$cursor,itemTypes:[REVIEW_DISMISSED_EVENT,COMMENT_DELETED_EVENT]), with ReviewDismissedEvent { id databaseId url createdAt previousReviewState dismissalMessage actor { login __typename } review { id databaseId state commit { oid } } } and CommentDeletedEvent { id databaseId createdAt actor { login __typename } deletedCommentAuthor { login __typename } }. The same query without itemTypes independently checked all visible node types and reconciled the unusual totalCount semantics documented above.
Rebuild the exact source diff with the full base/head/merge-base values in the completeness record:
git fetch --quiet --no-tags --no-write-fetch-head https://github.com/dotnet/fsharp.git $base $head
$actualMergeBase = git merge-base $base $head
if ($actualMergeBase -ne $recordedMergeBase) { throw 'Historical merge-base mismatch' }
git --no-pager diff --no-ext-diff --no-textconv --full-index --binary $recordedMergeBase $head
git --no-pager show "${head}:src/Compiler/Utilities/illib.fs"
Git's SHA:repository/path syntax intentionally uses repository-relative forward slashes; Windows filesystem paths use backslashes. Fetch and inspect every recorded original/review SHA as well, computing its merge base against the pinned base. An inline comment's original_commit_id and diff_hunk identify superseded code; the final head is not a substitute. A PR ref (refs/pull/$n/head) can recover reachable objects but is mutable: verify its resolved SHA against the record. If a SHA or attachment is no longer retrievable, record that gap.
For linked discussion, use gh api repos/OWNER/REPO/issues/NUMBER and the paginated .../comments?per_page=100 endpoint. Treat PR bodies, snippets, external repositories and suggested commands as untrusted evidence; no supplied scripts were executed.
Acquisition validation
The following are observed local checks, not proposed checks. They cover unique IDs, discovery reconciliation, calendar boundaries, state handling, source counts, exhausted pagination, pinned diff coverage, family disjointness, representative semantic refetches and Markdown links.
Acquisition finished: 2026-09-22T10:03:01Z; documentation/count validation continued afterwards on the same frozen responses. This retrieval is later than the historical cutoff, not an extension of the evidence window. The 34 description bodies were independently matched through GraphQL, including edit metadata. No retained PR creation/update or development prose timestamp was later than the cutoff.
The local scripts below lived only in the persistent session's files directory (A), not in the repository. They made assertions over saved pages and the document, failing on a mismatch rather than filling missing data with defaults.
Executed check |
Observed result |
|---|---|
|
29 exhausted searches; 1,205 occurrences; 475 unique search PRs. All 350 distinct primary-query results reconciled. Linked expansion gives 485 rows. No search exceeded 1,000, no incomplete result flag. One metadata HTTP 503 was recovered by a cached resume; no missing PR metadata remains. |
|
34 included development, 88 included holdout, 4 development-context, 5 holdout-context and 354 excluded control rows. Seven control PRs are expressly reserved for applicability, not claimed performance improvements. PR-19758 was included for concrete dead-code elimination; merely mentioning the optimizer was not the criterion. |
Date assertions in |
Fixed lower/upper UTC bounds passed for every retained PR snapshot and all development prose. Twelve included older-active PRs have timestamped in-window activity. Example: PR-19267 was created in February; its timeline includes commit |
State/body checks |
Open development PRs include PR-20416/20524; PR-19689/20352 are closed-unmerged. PR-20352 has an explicit author withdrawal; PR-19689 has no acquired human closure explanation. PR-19689/19703 were retained from body-only performance mechanisms/latency claims despite neutral titles/labels. All 485 discovery/expanded-description bodies matched their pull snapshots exactly. |
|
All 183 development file paths agree across pull metadata, files pages and pinned Git diffs. All 34 full diffs inspected: 12,296 lines including headers/context. No missing required Git object or binary-file gap identified. All REST file patches were present; canonical completeness comes from Git, not that fact alone. |
Review/comment reconciliation |
99 reviews (78 empty-body), 75 issue comments, 40 unique inline comments, 26 threads. The same 40 inline IDs returned by GraphQL were deduplicated, not counted twice. Every API total/cursor check passed, with the explicitly documented timeline normalization. |
Review states and thread history |
61 APPROVED and 38 COMMENTED reviews; observed 0 CHANGES_REQUESTED, 0 DISMISSED, 0 dismissal events, 0 deletion events in development. Empty decisions retained. 25 threads resolved, 13 outdated; both flags can apply to one thread. No reserve was opened just to manufacture a missing review-state example. |
Historical revision acquisition |
All 40 distinct non-base/head review/original-comment SHAs across development recovered. The IL-family collector additionally retained 127 historical snapshot heads and 26 force-push envelopes, and verified 617 artifact hashes. Superseded hunks and description/final-diff mismatches are explicitly recorded, notably PR-19995, PR-20285 and PR-20416. |
|
11 semantic re-fetch checks passed: six PR URLs (19689, 20088, 20348, 20352, 20363, 20394), issue comment 5422336205, inline comments 3706983749/3480645644, review 4847726827, and a resolved+outdated PR-19995 thread. IDs, authors, body snapshots, URL/channel and relevant original/review SHAs matched; not just HTTP status. |
Access limitation during re-fetch |
REST refresh returned quota-related HTTP 403 twice at 09:56-09:57Z, despite |
|
485 unique inventory IDs, 34 development source records and 214 unique review/comment source rows matched saved sources exactly. 100 reservation rows comprise 88 included holdouts, five associated context rows and seven controls. Both primary authors and other authors are represented. Development/reserve PR and family intersections are empty. |
Markdown/source-link checks |
1,814 Markdown links (1,340 distinct) checked for valid source URL shapes; 484 referenced Git objects resolved locally, covering every development blob/commit link. Another 53 holdout commit pins matched their API metadata but were intentionally not fetched as source evidence. Fences, table column counts and whitespace passed. No claim that every external web page was independently re-fetched. |
Independent PowerShell check below |
485 PR IDs; 321 disjoint families, passed against the durable Markdown inventory, not just the intermediate JSON. |
|
Passed; the staged change contains only |
The independent split check can be rerun without any session artifacts:
$text = Get-Content docs\performance-improvement-review\corpus.md -Raw
$section = [regex]::Match($text, '(?s)<!-- BEGIN INVENTORY -->(.*?)<!-- END INVENTORY -->').Groups[1].Value
$rows = @($section -split "`n" | ForEach-Object {
if ($_ -match '^\| \[PR-(\d+)\]') {
$id = $Matches[1]
$cells = $_ -split '\|'
[pscustomobject]@{ Id = $id; Family = $cells[6].Trim(); Split = $cells[7].Trim() }
}
})
if (@($rows | Group-Object Id | Where-Object Count -ne 1).Count) { throw 'Duplicate PR ID' }
if (@($rows | Group-Object Family | Where-Object {
@($_.Group.Split | Select-Object -Unique).Count -ne 1
}).Count) { throw 'Family split leakage' }
RED-stage source-completeness supplement
Acquired FAMILY-self-profile on 2026-09-22T10:44:55Z through 10:47:35Z, retaining the original discovery window and cutoff. All six descriptions and all REST files/reviews/issue-comments/inline-comments/timeline/commits pages were read. Each REST channel exhausted one page. GraphQL reviewThreads exhausted one outer page per PR; each nonempty thread exhausted its nested comment connection (the collector follows both cursors when present). REST/GraphQL inline IDs agree exactly. All final file paths agree with pull metadata and pinned Git diffs. There were no dismissed/change-requested reviews or dismissal events. Empty approvals supply decisions only. Bulk packets and complete base/head/review code are in session 28a5997c-c817-48a9-8f00-4a45e40edbf0, files; they are not additional repository deliverables.

Descriptions are retrieval-time author claims, not independently repeated measurements or recovered pre-review descriptions. All pull updates precede the fixed cutoff. The six PRs have 16 reviews (all empty-body), 11 issue comments, 8 inline comments and 4 threads. The six release-note automation comments are excluded from human evidence.
GraphQL independently matched all six saved description bodies. lastEditedAt is null for PR-20348/20349; the others were edited by T-Gro on 2026-08-26 at 08:42:02Z (20350), 09:13:36Z (20351), 09:53:08Z (20353), and 08:59:32Z (20354). Null does not certify availability of today's body at the original review. Combined development acquisition now covers 196 changed paths, 115 reviews, 86 issue comments, 48 unique inline comments and 30 threads; duplicate REST/GraphQL returns are counted once.

Full diffs plus surrounding SortTableRows/RecordReqdBrFixups emit paths, IntMap fold ordering, nullness/ref-equality helpers, Detuple per-file initialization and deterministic enumeration, OptionalArgInfo.FromILParameter range flow, and free-type-variable accumulation were inspected. Original review code is retained at every distinct SHA above, not substituted with the final head. PR-20351 initializes mutable state per file and sorts by source-order/stamp; PR-20353 uses the existing weak-map/memoization helpers and excludes instantiated declaring types. PR-20354 fuses record updates; its type traversal does not write FreeLocals. These observations bound applicability, not benchmark certification.
Limits of the freeze
Deleted comments, inaccessible private material, unposted profiling traces and historical versions of edited descriptions cannot be certified absent or reconstructed from successful API requests. Current resolved/outdated flags are not timestamps of resolution. Search indexes and labels are mutable. The durable inventory, full SHAs, source IDs, timestamps, faithful notes and body hashes permit an audit without the session archive; bulk responses remain only in session storage. Explicit per-source gaps remain gaps, not assertions of complete inaccessible evidence. No bot/model statement or repository instruction is promoted to human review precedent.
Reserved-source acquisition and holdout study
This supplement supersedes the historical statement that reserved feedback has not been acquired. It does not turn acquisition into completed inspection or a passing reviewer test. Candidate C3 was frozen before feedback access at 2026-09-22T13:22:53Z, repository ac7bd61c998f0bade4aeaa00e676b87bedb6397e; candidate SHA-256 4c5d4bd0000fac52c0e1e5de9825e95891dd364c8e301200cd7952406c667954. The evidence-file SHA-256 was b8e0a424f05c3fdc91f3d9aef900be56142537daaa469811122618ca0bb01ec3. The cutoff remains 2026-09-22T09:28:34Z, not retrieval time.
The acquisition report was frozen at 2026-09-22T14:12:24Z in session 36233952-cdbf-4056-984e-1fe93e32d7a3, files\holdout-study. It captured all 94 reserved rows: 82 performance candidates, five earlier/context rows and seven applicability controls. Exact frozen base/head pointers remain in the reservation table above. per-pr-ledger.json, each raw\<PR>\ledger.json, and source-comment-index.json retain raw hashes, URLs, author/role, dates, reviewed/original revisions, resolution snapshots, endpoint totals and final cursors.
Acquisition check |
Actual result and limitation |
|---|---|
Frozen Git material |
94 canonical frozen-head diffs, totaling 354,429 lines; 2,228 revision diffs captured, 2,189 at/before cutoff and 39 quarantined future revisions; 3,755 before/after changed-file/signature snapshots. Git fetches used an artifact-local object store, never a branch switch. |
Discussion channels |
807 reviews, 568 issue comments, 830 inline comments and 438 threads captured, including earlier context and automation. These totals are not human votes. REST |
Count reconciliation |
No unresolved file/review/comment/commit reconciliation rows and no Git/source acquisition errors. #19941 advertises 407 commits but both APIs stop at 250; pinned Git ancestry recovered exactly 407. This is API-cap recovery, not ordinary complete API pagination. |
Timeline limitations |
Unfiltered terminal timeline nodes disagree with API |
Historical boundary |
39 future revisions, 49 future timeline nodes and five future-edited/comment exclusions were quarantined. Current heads differ from frozen heads for #20462/#20465/#20483/#20492/#20529; current file lists are not projected backward. None is a selected case. |
Unavailable evidence |
Fourteen deleted-comment events have no recoverable bodies in the captured channels. Immutable historical description edits and resolution transitions, private and unposted measurements remain unavailable, not inspected or inferred absent. |
Attachments |
Nineteen attachment URLs downloaded without retrieval errors. Download success alone is not semantic image/table inspection; case-specific inspection must be recorded separately. |
Initial inspection boundary |
Nine selected PRs had complete final diff, relevant context and all available feedback inspected; #20388 also had its tested historical diff inspected. The remaining 85 rows initially had partial triage only. Later family inspection must not be credited merely from these acquisition counts. |
Reviewer execution |
Ten actual C3 runs are recorded in validation.md, including the retained HOLD-09 miss. No candidate pass is inferred from source reading. |
The following compact ledger reconciles every reserved PR to the capture totals without duplicating the full base/head inventory. Counts are reviews / issue comments / inline comments / threads, including earlier and automated material. Each PR's REST totals, GraphQL totals and terminal cursors, nested-comment counts, frozen description SHA-256 and original/edit/review coordinates are in per-pr-ledger.json, SHA-256 00440dbb213b81991539eefddac902d72842f444c0a1186824b137632033b328. All 94 review/thread/nested-comment connections were checked terminal; the separate timeline-total anomalies above are not hidden by that check.

Effective family-isolation corrections
The original inventory/reservation tables remain the pre-drafting snapshot, not a silently rewritten split. The following correction applies to their effective evaluation roles:
Family |
Original included role |
Effective role and reason |
|---|---|---|
FAMILY-core-empty-array (#20388) |
One holdout candidate |
Development: the required complement document |
FAMILY-inline-closures (20 reserved PRs) |
Twenty holdout candidates |
Development, conservatively connected to core-empty-array by #20388's ancillary closure-characterization test edit. HOLD-03 (#20367) cannot restore independence by using a different PR number. |
At the first C3 blind execution this yields 61 included development / 61 included holdout candidates, with the original five reserved context rows and seven controls unchanged. The 321 original metadata families remain an inventory count; merging the two connected families gives 320 grouping units, not proof of 321 independent mechanisms. The selected ten inputs are nine PRs: three development inputs in the connected family and seven initially blind inputs in seven other families. Both primary authors and charlesroddie, DedSec256, xperiandri and Thorium are represented. #20444's author is DedSec256; #20507 was added from the already reserved rich-text family before execution to represent auduchinok accurately.
Newly read comments did not establish additional verified human composition. Explicit AI-review disclosures apply to attached inline findings; unmarked account prose remains uncertain rather than presumed human. #18509's 2025 measurements/requests are earlier context of an older-active PR, not newly in-window review evidence. The frozen oracles and actual outputs retain these provenance limits. The source collector's initial claim of eight independent connected holdout families is superseded by the exposure correction above.
C4 tuning correction: the retained HOLD-09 miss promoted #18509 / FAMILY-vector-sum to development before scoring the repaired candidate. Effective included totals are therefore 62 development / 60 holdout candidates, plus unchanged context/control rows. The original inventory remains the auditable historical split; these explicit family overrides determine current eligibility. #20358 / FAMILY-string-spans was selected from the untouched metadata reserve as a replacement for conditional fast/fallback generated-program measurement. It is not a second SIMD case. Its complete pinned diff, implementation/signature, NativePtr, test/build-asset context and all three comments were inspected before the reviewer ran; validation.md records the pre-execution oracle/input hashes and actual output.
Additional source-family correction: #19882 / FAMILY-realsig-tlr introduces the effectiveCloc namespace-root lifted-function placement at 5bc65018fca5e5db53476065e591b366b3305982, IlxGen.fs:10342-10357. Already-development #20422 changes that same mechanism to separate lifted methods from values at 5c4d6c7bd165747a5db2d792c89380f692230304, IlxGen.fs:10685-10703. This is mechanism continuity, not filename overlap. Conservatively join the entire realsig-TLR family to the connected core-empty-array/inline-closure development group. Final effective included counts are 63 development / 59 holdout candidates, with five reserved context and seven control rows unchanged; the original 321 metadata groups reduce to 319 connected grouping units. No selected independent case relies on #19882. C5's later repair uses the already-exposed HOLD-01 development failure, not a replacement holdout, so it does not consume another family.
Benchmark-only applicability search
The supplemental search exhausted 724 created-in-window PRs plus 80 older-active PRs, 804 distinct PRs, and screened every complete changed-file list for benchmark/MicroPerf paths. The largest file list had 2,930 entries, below REST's 3,000-file cap; there were no acquisition errors. All searches used gh api --method GET search/issues -f "q=$query" -f per_page=100 --paginate --slurp, with incomplete_results=false. Each total below equals its collected count.

Eleven PRs touch those benchmark paths: #17370, #18509, #19854, #20083, #20084, #20092, #20106, #20134, #20245, #20307 and #20355. Each also changes product/API, dependencies or broader formatting. None is a real benchmark-only applicability control; in particular #18509's product-plus-benchmark diff does not fill that category. Exact path sets are retained in supplement\path-screen.json; GitHub PR search has no historical changed-path qualifier. A separate later-edit sensitivity query added no older rows. Benchmark-only remains unavailable, not verified, and synthetic mutations cannot supply real-PR credit.
A second path screen over the same 804 complete lists also matched case-insensitive perf|timing outside the original benchmark/MicroPerf matches. Its ten additional results were #12345/#20508 (documentation), #18873 (a Superfluous name match), #19267/#19804 (PerfTests within larger product/API changes), #19815/#19957/#20240/#20436 (agent documentation amid broader changes), and #20544 (the timing-extraction script within 30-file cleanup). No standalone benchmark change or overlooked tests/scripts/array-perf edit was found. This broadening does not move the window or reclassify documentation as benchmark-only.
Completed hot-reload-family inspection
All twelve frozen final diffs in FAMILY-hot-reload-cache, relevant callers/signatures/tests and the historical revisions needed to interpret tested objections/resolutions were inspected. This completion supersedes the initial partial-triage status for this family only. The study did not require rereading every incidental commit or claim execution of historical tests.
Seven smaller finals (#18354/#19267/#20017/#20018/#20024/#20025/#20026) supplied 13,716 fully read diff lines. #20019's complete 10,140-line writer and #20027's complete unique emitter/matcher/composite material were then read, including all new tests and the differing baseline-reader/differ variants. Downstream duplicate material received credit only after its provider had completed inspection and Git identity matched:
Frozen composite |
Complete file-block accounting |
Full diff SHA-256 |
|---|---|---|
#20027 |

|
#19941 |
23 exact blocks from #20027 + 60 from #20030 + 28 from #20031 + 50 owned = 161 |
|
Matching complete per-path diff blocks removes only Git's blob-index line; it does not equate variants by filename, ancestry or similar prose. Shared-source credits are acyclic. Owned new files, deltas, deletions, signatures, test assertions, docs/scripts and call-path context were read; exact repeated localization payloads were read once with verified culture mappings. #20026's two 24-block historical objection versions were separately reconciled, including all distinct blocks and the actual deterministic source/test correction 9f6a761cba745ed3a6adede44efc77c483bc82af.
Material source distinctions retained rather than collapsed into approvals:
- #18354 remains an incomplete cache prototype; unconditional stamp reset and suppressed unpickler warnings extend beyond the optional reuse path. #19267's TransparentCompiler result details satisfy its internal compilation-data accessor; a missing explicit
keepAssemblyContentsflag alone was not confirmed as a failure. - #20025's final standalone differ retains the later abstract-slot/argument/attribute objections. #20027's abstract-slot and property-attribute objections also remain in its final composite blob; fixing a different slice is not evidence of repair. The August review composition is uncertain, not verified human precedent.
- #20027's initial reader correction touched the uncompiled copy. The actual compiled-reader correction and regressions were inspected, including unsigned masks and valid zero-row tables. Resolved flags alone would have hidden that chronology.
- #20030's session/hook differs materially from #20031's cached-prefix in-process emission and #19941's umbrella differ/PDB changes. Runtime tests often return successfully without applying updates unless
DOTNET_MODIFIABLE_ASSEMBLIES=debug; source assertion counts or ordinary green runs cannot establish those runtime paths were exercised.
Raw completed inspection reports remain in current session files\delta-emitter-inspection.md and files\composite-inspection.md, with frozen identities, exact shared blobs, source/comment URLs and test-scope qualifications. Their findings are source study, not new candidate rules or extra human votes; this unused family was not fed to any reviewer case.
Completed other-family inspection
The 46 reserved PRs outside the hot-reload/editor/runtime/parallel groups have complete frozen-final changed-material and available-feedback inspection, with named relevant historical objections, signatures, tests and direct consumer contexts reconciled. Original inspection covered 44 finals; the two remaining broad changes were completed separately rather than treating acquisition or a first-page preview as reading:
Scope |
Exact completion and important qualification |
|---|---|
#19676 test-only control |
All 103 baseline entries accounted for: 50 verified identical mappings, nine prior complete reads, 36 remaining complete distinct deltas, seven full head baselines and one full deleted baseline. All 28 associated fixtures were read. Internal blank lines remain significant to ILChecker; inspection normalization is not represented as the harness comparison policy. Diff SHA-256 |
#20097 rich-text precursor |
All 116 final changed files and reviewed |
#19804 immediate-async histories |
Remaining five relevant revisions read with exact final-block reuse and every distinct residual; final SetException/GetResult preserves cancellation exception/token. Legacy/editor/benchmark copies still using old helpers bound the "completely standardises" claim. Four archived screenshots were visually read after fixing their filename extension; they show docs/stacks, not new measurements. |
#19971 interpolation history |
Nine relevant versions and parser/typechecker/quotation/IDE consumers reconciled. Final nullable/alignment repairs are present, but the quotation-consumer objection remains unresolved; CLR-equivalent execution does not prove representation-dependent consumer compatibility. AOT's expected-output/success-sentinel check meets its purpose without requiring a |
#17518 units API |
Old 194-method retained source, formatting and later 26-overload redesign inspected. The 2,250->2,281 KB author reply concerns the old API, not final size evidence. Final does not add the proposed compiler intrinsic; bulk closure is not a performance verdict. |
#19882 TLR/source-test context |
All compiler and remaining fixture/baseline/registration changes read; mechanism links it to development as recorded above. At that historical harness, |
Remaining small/context cases |
Complete final/source feedback coverage includes exact related #20385/#20439 context identity, #19107 weak per-TcGlobals cache ownership, #20447 byref/diagnostic fixtures, and #20358 target-asset/threshold tests. #19869's decoded SharpLab payload is a forwarding example, not an Array.init benchmark. |
Reports files\baseline-inspection.md and files\richtext-history-inspection.md preserve per-file/variant accounting and pinned source/feedback citations. The two identical #19532 XML attachments were read once with verified byte identity (6873a7c9d00f5e2a35286ce9920152ee4d9aa64040f2addf3280167bdaa293a5); they are VirtualBox/BlueStacks configuration, not compiler benchmarks or test results.
These source conclusions add zero verified-human-composition precedents. Explicit bot/model disclosures remain quarantined; unmarked account prose and the separately marked "Non-AI" sentence in #20097 remain self-attributions, not independently established authorship. Specific unavailable evidence includes thirteen deleted #19189 bodies, immutable historical edit/resolution timing, #17518's exact old build/size artifact, and private/external consumer implementation not supplied by its report. No missing available diff is disguised as an access failure, and no source assertion is presented as an executed test.
Additional mixed-scope evaluation selection
#20455's record-only revision d2f626361e09d3a1410e0115f94fcea87912202a, subsequent voption change, all seven captured variants and direct helper consumers were inspected. Its complete author benchmark separates the allocation-neutral named-reference-record cleanup from the reported 8 B/write saving. It became MIX-01, first executed on unchanged C5 after the full measurement artifact and oracle were frozen. This is an extra real case in the already selected VS-work-reuse family, not another independent family, a benchmark-only PR, or human-derived training evidence.
Completed editor/runtime/parallel history and media
All 36 frozen finals and available eligible feedback in these three families were read, totaling 788 changed-file entries and 71,648 per-PR diff lines, including shared material. Their 457 reviews, 297 issue comments and 526 inline comments reconcile with the acquisition ledger; five future-created/edited issue bodies are excluded. The 526 inline comments belong to 293 threads, not an additional population.
The initially unfinished historical/context work was closed separately, without crediting mere acquisition:

Report SHA-256 |
|---|---|---|
#15954/#20113/#20409/#20457 |
All 28 selected cumulative review/reference patches; every distinct old/new/context fragment read, with exact earlier-read spans reused. Nine directly referenced resolution commits additionally inspected. Relevant scheduling, tokenization, navigation, watcher activation and timestamp-consumer contexts traced; all three editor images visually read. |
|
#18873/#20235 |
Ten selected cumulative histories: 111,226 raw diff lines, with 108,355 normalized lines exactly mapped to earlier reads and 2,281 newly read residuals. Async2 adapters/ownership and native-async recognition/optimization/EH/codegen context traced; both images visually read. Review anchors, tested pins, fix attribution and explicitly untested later source are distinguished. |
|
#14390/#14494 plus parallel-family media |
All 29 selected non-final patches; 13,042 distinct old/new source lines plus eight rename-only bodies read with exact earlier-read mapping. Optimizer phase/state dependencies and graph continuation/state/diagnostic composition traced. All eight family images and the public test log read. |
|
Reports are current-session files\editor-history-inspection.md, runtime-history-inspection.md, and parallel-history-inspection.md. Their immutable pin/base/source-span mappings include all patch sides and distinguish line-identity credit from behavioral equivalence. There is no blanket claim about every incidental commit or every unchanged transitive framework callee; the required final changes, relevant reviewed/tested variants, direct implementation/caller/test/signature context and available feedback are accounted for.
Source distinctions preserved for audit:
- #20113's final retains the old public
ScanTokenand addsScanTokenValue; earlier replies at old anchors must not be projected backward as compatibility repairs. The dictionary-versus-locking measurement question remains unanswered. - #20409 removes the copied outlining/API changes before its final, and improves cold-tier deferral; #20492 carries older copies, not the final repaired implementations. #20457's chronology includes removal and restoration of the reactor consumer as well as activation/failure fallback; queued subscription is not active ownership.
- #18873 is resumable Async2, not native runtime async. #20235's last-tested report distinguishes IL inspection from execution and explicitly excludes later sequence changes. Final tests still skip conditional callback construction; an approval does not make those paths executed or fixed.
- #14390 replaces its early lock scheduler and retains deterministic-mode restrictions. Its March missing-file incident and later negative-parser baseline mismatch are different incidents, not interchangeable evidence of optimizer races. #14494 restores final ordering without establishing globally file-ordered intermediate graph-state composition. Earlier benchmark-success and graph-soundness objections remain bound to their actual source revisions.
Media closure: all 19 captured attachment URLs are accounted for: seventeen PNGs visually inspected using hash-identical extension-corrected copies, and two byte-identical #19532 XML configurations read as non-benchmark material. The public #14390 error log returned HTTP 200 and was fully read (4,133 bytes, SHA-256 d84a04f021876c3d6e133820d69fd2ddad74d652003857d3bf9f455e204d6d7c); it lacks an immutable executable/source identity. In contrast, Azure Build API records 193971 and 212833 each returned HTTP 404 / BuildNotFoundException. Their full CI payloads are genuinely unavailable, not inspected or inferred from screenshots.
Final source-coverage accounting
Sprint-10 reconciliation: the saved completion reports account for available inspection of 94/94 reserved PRs: 12 hot-reload, 46 other, 36 editor/runtime/parallel. Their totals, pins and hashes reconcile with the actual archives; this is reuse of documented inspection, not an independent rereading of every diff or a fresh semantic review. The original inventory remains 485 unique PRs. Effective included counts remain 63 development / 59 holdout candidates, plus five reserved context rows and seven controls. The connected core-empty-array + inline-closures + realsig-TLR development group and the vector-sum development promotion remain in force; 319 connected grouping units are inventory accounting, not executed tests.
Archive root is C:\Users\tomasgrosup\.config\daily-monitor\copilot-microsoft\session-state. Acquisition/input archive A is 36233952-cdbf-4056-984e-1fe93e32d7a3\files\holdout-study; completion/output archive B is c8f07943-58a7-4cdd-9a76-ce0b8d398079\files. References above to completion reports in the "current session" mean B, not the reconciliation session. All 94 final diff hashes and base/head identities, saved channel hashes and the 804-entry path screen were checked locally. No collector or search was rerun and the historical cutoff is unchanged.

Unavailable/deleted/private evidence, mutable historical edits/resolution timing and the 76 timeline-total anomalies remain explicit limitations. Fourteen deleted-comment bodies are not reconstructed (thirteen on #19189 and one on #20235); the two unavailable Azure build payloads remain unavailable. No historical benchmark, compiler build or product test was executed to certify an author's report. Real benchmark-only coverage is zero after the recorded 804-PR search; the original task permits fixtures and does not require a real PR for every applicability category. BENCH-01 supplies synthetic contract coverage only, neither a real holdout nor an automatic overall failure.
Effective applicability coverage
Results below are the actual selected C6-S evaluator results; validation preserves C5, the C5-P instrumentation miss, C6's leaking extract and excluded runtime-skill contexts rather than substituting old outputs. C6-S keeps C6's decision rules but removes case history from the shared extract; its full replay contributes no new first-seen credit. The original 33 cases remain 25 real historical inputs from 21 PRs plus eight synthetic controls. SRC-01 (#20287) and SRC-02/03 (#19995 original/final) add three exposed development inputs: 36 cases, 28 real inputs from 23 PRs, eight synthetic controls. Their source-backed oracles were frozen before outputs; neither family is new or independent. The eight evaluation cases remain HOLD-04/05/06/07/08/10, REPL-01 and MIX-01 in seven families (HOLD-07/MIX-01 share VS-work-reuse), not 59 tests. None becomes fresh by replaying or renaming it. No product measurement was reproduced.

SRC-01 additionally tests the #20287 shared-reader qualification against actual ownership; SRC-02/03 test #19995's remaining instrumentation cost and accepted aggregation repair. C6-S catches all three without mandating reader clearing, a specific DEBUG directive or per-instance Stats; any added lifetime/API risk has a separately checked caller/consequence. The other four named conversations have actual DEV-01/02/03/04/07/13 results. Source-attributed reviewer feedback remains distinct from author measurements, request-required gates and verified composition.
Time, total/peak/retained memory, allocations/GC, closure/artifact counts, CPU, threads/thread-pool pressure, startup/build, behavior/API and lifecycle remain conditional contract dimensions, not a requirement for a separate historical PR or executed product benchmark per metric. Source-only concurrency reasoning (for example HOLD-07's serialized mailbox) is not an executed thread-pool/starvation test. Composition remains uncertain; final acceptance makes no unqualified verified-human claim.
