+# Private retained-entry producer prerequisite
+
+Base `97a8703adc75467a7f8e75f5c6cb00ca542b707c`; implements the accepted
+`harness/analysis-entry-producer-contract-20260925.md` in the parent source tree.
+This is fixture-only phase/producer evidence, not emitted-output admission.
+
+The explicit entry route also enables text producers and derives C and exact
+policy from the existing carried guard. Budget adds only optional scalar C/M.
+Existing legacy, carried-phase and text-only entry paths retain their checkpoints.
+U keeps its original event sites and work-limit precedence; prospective aggregate
+checks latch without changing totals. F is installed before traversal. Private
+State helpers reserve unique value-end keys and lexical owner occurrences before
+mutation. Successful grammar events count projection slots with checked addition.
+The new route reserves token-end slots and projection together, without the old
+borrowed-work counting Vec. A scalar quota checks each projected envelope, field
+and actual value before growth. Synthetic bodies remain included in seven.
+Per-file actual map/owner lengths and final independent metadata reconcile M;
+resolver C then U+M transfer and text reconciliation are unchanged.
+
+Six tests in `mixed::carried::entry_producer` cover independent literal E and H
+syntax caps 13/12 and 25/24 separately from resolver 17/16 and 29/28, owner/value
+prefix refusals 4/7, and the 344-byte nested syntax-only fixture (U13, M89, P30,
+C1; 103/102). They check node/element envelopes, nested positions and owner order,
+quota underflow/leftover, direct unchanged collections on refusal and repeated
+map-key replacement. Labeled arithmetic controls exercise overflow, sticky-first
+failure, prospective U and work-limit precedence. Whole OA/SA Project, warnings,
+Usage, numeric work and retained totals are compared with text-only under actual
+and explicit zero guards. Old-route diagnostics and original bytes are checked.
+All byte policies are roomy 4096 so earlier text limits do not mask entry tests.
+
+Source review identified a possible internal overflow call overwriting an already
+latched error. The helper now returns the first failure; a direct fault control
+checks that behavior. Repeated map keys now perform a zero-delta reservation
+before replacement, preserving a latched refusal without modifying the map;
+a direct control checks that branch too. These were corrected before compilation,
+not a runtime bug
+observation. Test review also caught that the independent inventory walker adds
+its own existing scratch slots: exact-cap ordinary syntax controls remain at
+29/37/103, while a separate roomy owner of the same literal runs that walk.
+No live policy is widened and no exact-cap resolver success is implied.
+No prior tests, stack sizes, policies, inherited failure dispositions
+or unrelated formatting are changed. Only touched Rust files were directly
+formatted with skip_children. Parent owns compiler, full disposition, Clippy,
+format and prologue/stack acceptance; no runtime result is claimed here.
+
+Allocator overhead, token storage under its existing token ceiling, delimiter and
+other work stacks, numeric/decoder internals and model/validator heap remain
+outside this retained metric. The extra shared projector wrapper and scalar
+Budget/State fields require measured parent stack checks; no heap indirection or
+larger stack is introduced. Final output acceptance remains a separate task.
+
+Initial a629ae01 focused compilation failed before any test ran: the quota
+control's unwrap_err required Debug on its successful EditDeclaration vector.
+The test now matches Err explicitly and panics on unexpected Ok, preserving
+the same assertion without changing production types. Original compiler output
+and source-bound receipt remain with parent gate evidence.

+`harness/analysis-mixed-acceptance-contract-20260925.md` (root b86c8dbc) within the
+private experimental mixed source path. No public source8, save, history,
+installation or repeated carried-source emission is enabled.
+
+A consumed PendingRename now verifies its actual complete bundle through the
+combined text/entry producer parser and existing complete resolver/admission.
+CarriedInput and its slim guard borrow that entire pending owner; covariance
+shortens the desired borrow to the verification scope without another parser
+lifetime, policy copy in guards, arbitrary tuple constructor or heap wrapper.
+Narrow immutable views supply the exact bundle, policy and retained O together.
+The existing fixture constructors and old parser modes remain available unchanged.
+
+The actual resolved expression arena supplies E for equality reservation against
+its full live storage. Complete actual Project PartialEq compares every field
+with desired; old name-exempt equality and pending's original E are not used.
+A static entry/default-span diagnostic reports mismatch. Warning inventory uses
+an exhaustive borrowed diagnostic-field match, checks empty related/non-Error
+shapes and sums checked entries/text. O+W is checked as a componentwise live
+subset and against inherited ceilings without resetting or double-charging the
+full ledger. Actual model/warnings move after equality; expression/occurrence
+arenas, syntax and complete pending guard drop before the bundle moves into
+AcceptedRename. Its private fields have read-only accessors, exact policies,
+final retained slots and separate verification Usage/numeric work; no input or
+desired borrow remains.
+
+Eleven new tests use the acceptance module filter. Independent minimal literal
+and whole model verify 152/151 through one unchanged profile; warning literals
+and full diagnostics verify 161/160 and final O+W=(2,0,157). Exact policy fields
+and a lexical scope dropping all inputs exercise returned ownership. Previously
+authored OA/SA/scoped-global swap and UTF-8/CRLF/all-file literals are reused,
+including an untouched fourth file. Equal-byte wrong alias/name, malformed
+source and parseable containment-cycle corruption separate equality, syntax and
+model-admission refusal. Actual E1->3 corruption plus a labeled internal ledger
+fault distinguishes reserving3 from trusting old1, without a fabricated late
+end-to-end equality cap. Other internal controls cover warning shapes, final
+subset and checked inventory overflow.
+
+Scoped 128 KiB workers perform actual verification/assertions/drop for deep128
+and wide129 expression nodes (success and target-only mismatch), plus the genuine
+151-byte late refusal. All original prerequisites are prepared outside those
+workers. Separate E0 target-only deep/wide and signed-zero geometry/scalar/history
+cases exercise complete equality. Positive-zero bits in actual returned model
+help distinguish moving the parsed model from substituting desired intent.
+
+Before execution, source review prompted correcting the carried module summary;
+parent readback caught an unnamed-source test slice, replaced with the exact
+independent 71-byte original literal. Local type inspection corrected the f32
+geometry bit assertion. These are pre-execution authoring corrections, not
+runtime failures. No prior tests or stack sizes are edited. Only touched Rust
+files were directly formatted with skip_children; compiler, full prior outcome
+comparison, Clippy, format and measured prologue/stack gates belong to the parent.
+No runtime result was claimed at that initial handoff; see the correction below.
+
+The selected retained/decode/equality domain remains logical, not universal heap
+or before-every-allocation accounting. Existing traversal/path-copy, delimiter,
+ordinary-open, Pratt and duplicate-name scratch keep their independent controls
+and stated exclusions; model/validator/numeric/decoder internals and native stack
+remain separate domains. File counts do not tightly bound traversal path bytes.
+Actual lifetime coercion and stack headroom still require the parent gates.
+
+## Initial focused failure and test-oracle correction
+
+Parent's initial focused run of `4872141c036c16825f1c098bd7cf44709897e814`
+compiled successfully and completed 9 passes / 2 failures. The failing assertions
+incorrectly required empty warnings in the rich OA/SA and four-file fixtures.
+The original run, log and artifact remain preserved under the parent's
+`analysis-output-acceptance-gates-20260925/acceptance-focused-4872141-1` records;
+artifact cba18de5 prefix, 43,060,224 bytes. Those failures are not erased or called
+production failures. The other nine controls, including both late byte caps and
+scoped 128 KiB verification/drop, passed in that run.
+
+Source-derived correction: validation.rs emits unallocated_leaf first, with
+field allocation and message "Allocate leaf 'Work' to a performer."; its later
+coverage.validate call emits work_without_behavior_context, field None, message
+"Include this leaf activity/function in a process/chain or scenario through a
+work action or exchange occurrence." Both are Warning, object ID2, empty related,
+and map to the full Work declaration. The first local derivation missed the
+coverage advisory; independent review caught it before the correction commit.
+The pre-existing project expected_leaf_work_warnings oracle confirms both/order.
+
+New tests now require both complete mapped diagnostics, with independent literal
+spans: rich OA/SA main338..403 line6 column1, or Unicode/CRLF351..416 line7 column1;
+four-file b.arcadia25..90 line2 column1. Warning storage is (2,0,227) for main,
+(2,0,221) for b.arcadia. Final rich entries5/text1169,1212,1243,1286 for OA LF,
+OA transformed, SA LF, SA transformed; four-file entries6/text747. Production
+acceptance and all original test bodies remain unchanged. This is a test-only
+oracle repair plus this note; corrected runtime acceptance awaits parent gates.

+# Ordinary source8 compatibility implementation
+
+Base `edf096cd33350865ecfc3c65ec266a6c0d3c4000`, selected parent contract
+`harness/ordinary-source8-compatibility-contract-20260925.md` at root fb9b0c5c.
+The public writer already emits8. The ordinary Parser::unit version list now
+accepts8 and its unsupported-version diagnostic names the accurate range.
+Current ordinary resolution already checks model limits and returns no migration;
+3–7 retain their existing migration paths. No new converter or dispatch adapter
+was introduced. Comments distinguish this ordinary repair from private mixed
+analysis authoring.
+
+Production change is intentionally confined to that version boundary. Long
+analysis constructors retain their explicit conversion refusal, and short typed
+declarations remain outside the ordinary grammar. Mixed cfg gates, formatter,
+public SourceIndex/update semantics, ID stabilization, resource/depth policies
+and codec switches are unchanged. Ordinary8 is not complete analysis/source8.
+
+Six new tests use the ordinary_source8 module filter. They reuse the substantial
+six-file source-project example and historical reviewed-prose fixture for complete
+model/current formatter and bundle/index idempotence. Other groups cover3–7
+migration to stable8; nested included declarations with omitted IDs, UTF-8/CRLF,
+comments and actual returned index/identity spans; stale compiled input; short
+and long analysis rejection, future/malformed headers and caller limits. Public
+checked-save exercises both source and JSON, actual returned bytes/reopen/repeat
+save, and rejection of the real formatter's omitted definition catalog while
+preserving existing destination bytes. These are authored evaluators, not passing
+execution claims. The three-file CLI preview literals additionally compile to an independently constructed complete Project before and after only the team alias changes; actual CLI execution remains a separate parent gate.
+
+The prior test exception below repairs fixture construction without weakening
+its semantics; all other prior test bodies/expectations remain unchanged. The16 formerly header-masked
+library workflows must run their intended nested/update/migration/transaction
+assertions; new downstream failures must be investigated on their own merits.
+Parent owns focused/full/integration/CLI/non-test consumer/Clippy/format gates,
+including previously unreached ordinary JSON branches. DEPTH_128_VALIDATED stays
+false, and ordinary8 does not qualify the private depth candidate, user-deferred
+Linux or the separately recorded full-pipeline setup limitation. Source/public
+save equality and no-staging-before-validation safeguards remain mandatory.
+
+Only changed Rust files were directly formatted with skip_children; source review
+found no production blocker. Compiler/runtime acceptance remains parent-owned.
+
+## Authorized pre-execution evaluator repair
+
+Independent integration inventory found source7_contract's
+source7_source_bundle_migration_is_token_only_and_new_link_stays_with_caller
+attempted to replace formatted header7 with commented6, although the formatter
+already emits8. That replacement was a no-op; the later expected7 was stale too.
+Parent authorized this one existing evaluator correction: first assert actual
+header8, replace8 with the original commented6 fixture, assert the comment and
+single6 token, and expect only6->8 during migration. All exact file/comment/module,
+whole-model, caller ownership and recompilation assertions remain, as does the
+original test name. This is a static finding before execution, not a reported
+runtime failure; no other legacy evaluator or formatter is changed.
+
+## Focused fixture repair after initial execution
+
+Parent's focused run at 33b86a4d completed five tests and failed one: the example
+bundle has no trace records, contrary to the new fixture's nonempty assertion.
+The repair explicitly authors a Participant trace from fixed OA rescue-team UUID
+102 to fixed SA system UUID301, checks endpoint kinds and the complete trace,
+and includes it in the unchanged whole-model source/bundle roundtrip assertions.
+Historical reviewed-prose trace/baseline coverage remains. Independent source
+review also identified the actual short case spellings oa_analysis/sa_analysis;
+both now appear in the ordinary refusal table alongside the invalid case aliases.
+Production and the other evaluators are unchanged. These corrections are not a
+runtime pass claim; the initial five-pass/one-failure record remains preserved.
+## Obsolete private header assertions after full execution
+
+Parent's full run at 520e50ce completed 298 tests: 294 passed and four failed.
+All 16 previously header-masked ordinary workflows passed. The four failures
+were private analysis tests that still expected an empty ordinary schema8
+project to be rejected. The scoped repair accepts ordinary8 with no migration,
+compares complete ordinary OA/SA projects where the existing fixed-ID fixtures
+provide that oracle, and explicitly embeds actual typed source or canonical
+text in schema8 to preserve public typed refusal. Declaration refusal coverage
+now includes versions3 through8. Existing numeric/lowering/model assertions stay.
+Only these evaluator names change:
+
+- inherited_version_root_and_short_word_contracts_do_not_enable_public8 ->
+  inherited_version_root_and_short_word_contracts_do_not_enable_public_typed8
+- public_source_headers_and_existing_numeric_token_controls_are_unchanged ->
+  public_ordinary_source8_preserves_typed_refusal_and_numeric_controls
+
+Production is unchanged. The initial 294-pass/four-failure evidence remains;
+repaired outcomes require the parent's next runtime gate.
+## Historical schema4 JSON oracle reconciliation
+
+Parent's r3_migration integration run at 0c07f53a completed four passes and one
+failure. Its whole-JSON expected value updated only schema_version, omitting the
+current definitions catalog. Project4::into_current already creates an empty
+catalog; Project serialization requires that schema8 field. The test now asserts
+that the original fixture has no definitions field and the decoded catalog is
+empty, then adds exactly definitions:{} to expected JSON. Complete JSON equality,
+historical baseline/prose checks, migration and reopen checks remain unchanged.
+No production behavior or frozen historical fixture changes.
+
+The parent reports completed core, six other selected integration gates and both
+actual CLI operations at 0c07f53a; that evidence remains reusable because this
+repair changes only the affected integration evaluator and this note. The initial
+r3 four-pass/one-failure record remains preserved. Parent owns the affected r3
+inventory/rerun and all-target Clippy/format checks on the repaired pin; this note
+does not claim their outcome or repeat unrelated runtime acceptance.
