+path in that candidate checkout while running from the measured SDK checkout.
+The driver uses the current working directory as SDK source; its exact offline
+scoring policy stays with the candidate driver, outside the model source view.
+
+1. On the recorded baseline `c0e7a130e06f2105034b149c0b479dc4eebc70ac`, before
+   changing the measured source, run
+   `node quality/sdd/ownership-qualification.cjs prepare`, then
+   `node quality/sdd/ownership-qualification.cjs capture baseline`.
+2. Run `node quality/sdd/ownership-qualification.cjs run baseline-1`, then
+   `baseline-2` and `baseline-3`. All three attempted outputs must remain.
+3. Apply the candidate source to that same checkout without changing the owned
+   fixture or case expectations. Capture `candidate`, then run `candidate-1`,
+   `candidate-2` and `candidate-3`. The recorded revised cohort uses `revised`
+   followed by `revised-1`, `revised-2` and `revised-3`.
+
+Preparation requires unchanged baseline source; captures and trials refuse to
+overwrite earlier attempts. Capture uses the actual application use case with
+in-memory ports to obtain analysis requests. Scripted stop responses create
+clarification history only; they are never scored as model predictions. Runs
+execute those requests through the actual SDK query composition and a matching
+read-only immutable fictional Git source. Reference verdicts remain outside that
+source and the model request. The probe never drafts, publishes or creates an
+issue branch. Its own fictional fixture has a local Git commit only.
+
+Artifacts live under `.tmp/bug-fix-evidence/856`. Keep the source fixture until
+queries and review finish, and retain its receipt, frozen cases, captures, raw
+predictions, identities and scores when retiring it. Reproduction may vary with
+the provider; the historical evidence records observations, not an accuracy
+guarantee. The versioned driver adds baseline preparation guards and an explicit semantic
+assessment gate. Capture, query, cases and expected decisions remain unchanged.
+
+Ownership questions never pass by keywords. After each trial, inspect every
+ownership question against that case's required decision. Write
+`<trial>-sdd-assessments.json` as a map from case ID to the structured assessment
+shown in `evidence/issue-856-ownership-assessments.json`, binding trial, case,
+response SHA-256 (`JSON.stringify(response)`), exact question ID/text, expected
+intent, assessor, rationale and verdict. Conflict cases also require
+`conflictIdentified: true`. Name agent assessments as such; this is neither human
+approval nor native PR approval. Dates or unrelated paths must be rejected even
+if their wording includes ownership-related keywords.
+
+Run `node quality/sdd/ownership-qualification.cjs score revised-1` (or the exact
+other trial) to produce a separate immutable semantic score. Missing or invalid
+assessments block qualification. A focused question cannot rescue a schema- or
+ownership-invalid plan. Re-scoring uses the unchanged domain parser and retained
+raw responses without model calls; it does not require the historical prompt
+implementation to be checked out. Original scores remain historical evidence,
+not proof that the old keyword scorer enforced the declared semantic criterion.
+All eighteen historical questions and all nine re-scored trials are preserved.
+
+
+An absent or invalid provider response is recorded as an invalid plan before
+question access or response hashing. The module exports its actual assessor for
+side-effect-free regression tests; importing it never starts a campaign. The
+source-bound tests exercise missing/null/primitive/malformed responses and valid
+object/string controls separately from the historical model observations.
+
+
+The separate working-branch supplement is documented in
+`evidence/issue-856-working-branch.json`, including all fifteen frozen scenarios,
+all baseline and candidate cohorts, exact source/request identities, explicit
+question assessments and limits. Its exact campaign coordinator is preserved as
+`evidence/issue-856-working-branch-driver.cjs.txt` for audit. It used the previously
+prepared fictional Git fixture plus a same-commit local branch alias and its own
+artifact namespace; it did not invoke the inherited historical preparation path.
+The twelve-case CLI above remains the original campaign, not a claim that its
+unmodified setup reproduces this additional SCM/state history. The executable
+public regression suite for that state flow is
+`src/application/usecases/steps/issue/__tests__/pre_branch_sdd_gate_use_case.test.ts`.

+#### 6.1.1 Ownership intent and unpublished proposals — #856
+
+This correction preserves the existing gate and semantic ownership
+validator. Two reported failures require separate treatment: an explicit update
+of a registered companion publication, and a later genuinely new package request.
+Both native runs expose `companion-path-registered`, but their rejected payloads
+and complete prompts are unavailable. Do not infer an exact rejected owner/path,
+a common internal cause or a regression against the current development SDK.
+
+Independent current-SDK execution demonstrates a narrower delivery defect:
+answers reach resumed analysis, while the valid preceding proposal is supplied
+only when a linked branch already exists. Four new regression cases fail against
+that implementation; the original 127 cases in that suite pass. Independent
+original-pin controls on both immutable consumer catalogs accept the intended
+`update` and `new` tuples and reject registered-path `companion` controls. The
+semantic guard is correct and MUST remain unchanged. One rejected contrast is
+explicitly authored; it is not represented as a hidden native response.
+
+| Request and catalog facts | Analysis action | Required behavior |
+|---|---|---|
+| Registered path owned by the selected capability, including a companion document | `update` | Preserve the owner/path and existing publication |
+| Existing capability, new unregistered publication path | `companion` | Justify a new document without duplicating ownership |
+| Unregistered capability and unregistered publication path | `new` | Provide complete proposed metadata; preserve other owners |
+| Conflicting or ambiguous intent/ownership | Valid provisional proposal plus blocking questions | Ask a focused ownership question before drafting/readiness |
+
+**OI-R1:** a document's role as a companion does not mean the requested operation
+is companion creation. Honor explicit existing-update and independent-new-package
+intent against the selected immutable catalog. Never relabel an invalid response
+automatically or weaken `companion-path-registered` to make it pass.
+
+**OI-R2:** after all current questions are answered by authorized actors, deliver
+the preceding unpublished proposal and its round alongside cumulative authorized
+answers when issue/profile identity and selected source still match. Include the
+actual proposed action, capability and path. Label it as unpublished context,
+never as a linked branch, existing publication or new execution authority.
+
+**OI-R3:** an unpublished proposal remains negotiable: preserve resolved intent,
+but allow an authorized clarification to require another valid route. Ask a
+focused question when that change is ambiguous. Once a linked publication owns
+the work, the existing same-owner/same-path update lock remains authoritative.
+
+**OI-R4:** stale body/title/profile/base, foreign cards, wrong issue identity,
+unauthorized answers and incomplete current answers cannot authorize reuse.
+Preserve the existing reset/wait/failure paths, round/answer bounds and source
+freshness checks. Do not resurrect an omitted or stale proposal as a default.
+
+
+**OI-R5:** an existing configured issue working branch is a source/routing fact,
+not proof that an SDD publication owns the proposal. When a current question card
+has no SDD-linked branch, retain its unpublished proposal even if a working branch
+was configured later. A generic working branch MUST NOT be promoted into the
+waiting card's SDD-linked branch while questions remain. Preserve ancestry,
+linkage, source freshness and authorized-answer checks. Once a validated draft is
+ready, retain the existing working branch in its draft record for exact routing
+and freshness; do not prepare another branch or accidentally verify the moving
+development branch instead. Existing card-linked publication reservations and
+verified published-owner constraints keep their prior semantics; no legacy
+provenance is guessed and no existing publication is reassigned.
+
+```text
+issue + immutable catalog -> initial ownership proposal -> numbered questions
+  -> authorized answers + matching unpublished proposal -> renewed analysis
+  -> more questions OR validated draft -> existing Action publication fence
+linked owning publication -> same-owner/same-path update only
+```
+
+Text equivalent: retain valid unpublished planning context across authorized
+clarification without claiming publication; published ownership stays locked.
+Existing pending, waiting, blocked, retry and published cards remain the user
+surface. Example question: “This publication is already registered under the
+existing capability. Confirm an update there or identify the new publication.”
+Use the effective issue locale and retain existing descriptive source/run links.
+A rejected model tuple still produces the current safe ownership diagnostic and
+same-issue recovery; it never becomes a draft or branch-ready result.

+
+One pure application policy renders the fixed route definitions and distinguishes

+the model still proposes and the existing pure domain parser decides semantic

+response-handling cases and 15 working-branch/publication cases. The older rows sum to
+176; this amendment reconciles the previously stale prose/total and adds 83
+without counting existing assertions or model repetitions as new cases.
+The floor is a requirement, not a claim that every historical case was rerun by
+the optional qualification probe.

+
+The subsequent working-branch review expands a separate prospectively frozen
+cohort to fifteen SDK scenarios: the unchanged original twelve plus three
+continuations where a generic issue branch becomes configured after the first
+question card. Declare three complete baseline and three complete fixed trials
+before changing production. Require 15/15 correct, focused ownership questions
+for ambiguity/conflict, and zero invalid plans in every trial and cohort. The
+original descriptor, all earlier trials and floors remain immutable. The owned
+fictional Git fixture receives a same-commit local branch alias only; its file
+tree and selected immutable SHA remain unchanged. Capture actual SDK requests,
+retain every prediction, and use explicit agent assessments for the two question
+scenarios in each trial. Additional request-equivalence captures cover branches
+present from initial clarification without claiming a historical provider replay.
+
+The completed supplement retains baseline scores 14/15 in each trial, first
+working-fix scores 14/15,15/15,15/15 and global-example revision scores 15/15,15/15,
+13/15. Those cohorts fail the unchanged per-trial floor. Contextual explanations
+of the actual recorded update/companion/new operation then pass 15/15 in all three
+trials, zero invalid plans. All ownership-question verdicts use explicit agent
+assessments. Initial-branch and late-branch captures have equal serialized
+application requests after correction; full provider stdin is not claimed equal.
+All 15 non-prompt fields and issue/answer/catalog/standard prompt tails remain
+unchanged across guidance revisions. The new semantics describe prior data only,
+never execution authority; current authorized changes retain precedence.
+
+The fifteen new deterministic cases reproduce 13 failures before the correction
+and preserve two successful publication/routing controls. All 170 cases in that
+route/source suite pass after correction. One older replay test is reconciled to
+check actual source/link/idempotence without falsely treating a generic branch as
+SDD publication; explicit first-publication failure/recovery tests retain their
+previous semantics. Complete evidence and the exact campaign-specific audit
+coordinator are registered under `quality/sdd/evidence/issue-856-working-branch*`.
+The full stable-catalog run passes 902 suites/17,704 tests with 35 pre-existing
+skips and 267 extension tests. All 31 changed coverable runtime lines are hit
+without partials locally; new-head review, technical checks and official Codecov
+remain required before merge. A prior catalog-equivalence failure came from
+updating evidence metadata during the run; the complete rerun held all 19 inputs
+byte-stable and passed without changing the validator or test.
+
+Before production changes, freeze twelve authored classification scenarios and
+exactly three baseline trials plus three trials for each distinct candidate.
+Capture actual use-case analysis requests and execute them through the real
+findings port in a matching immutable, owned Git fixture. Keep reference verdicts
+outside input. Codex/gpt-6-luna/medium stays fixed. Require every resolved tuple

+
+
+Initial #856 qualification on 2026-11-04 at `19396c58`: all 28 route cases and the
+127 existing cases in that suite pass; the full run passes 900 suites/17,649
+tests with 35 pre-existing skips. The 267 extension tests retain 100% coverage.
+All 14 modified coverable runtime lines are covered without partials locally;
+remote Codecov and current-head native review/CI remain required for merge.
+
+| Measured runtime | Correct per twelve-case trial | Invalid plans per trial | Cohort acceptance |
+|---|---|---|---|
+| Unchanged baseline | 6, 6, 7 | 4, 3, 2 | Failed |
+| First context/guidance candidate | 12, 11, 12 | 0, 1, 0 | Failed; retained |
+| Revised action/owner/path consistency guidance | 12, 12, 12 | 0, 0, 0 | Passed all 36 |
+
+The first candidate's rejected route used `update` for a new, unregistered
+publication despite its reason requesting a companion. A general pre-response
+consistency check addresses that contradiction without coercing parser output.
+The revised cohort was declared before that runtime change; fixtures, reference
+verdicts, model/effort and acceptance floors stayed fixed. Complete compact
+observations, source identities, limits and hashes for every raw prediction are
+in `quality/sdd/evidence/issue-856.json`; optional reproduction is documented in
+`quality/sdd/README.md`. This does not prove the unknown historical payload or
+consumer publication now succeeds. The original selected consumer catalogs and
+four original-parser controls are separate from the fictional model fixture.
+
+
+PR #885 review found that the original question scorer checked broad words rather
+than the declared focused-ownership criterion. Those legacy scores remain
+immutable historical observations and are not sufficient acceptance evidence.
+The correction requires an explicit semantic assessment bound to the exact trial,
+case, whole response digest, question ID/text and expected decision. Missing or
+invalid assessment blocks acceptance; conflict cases additionally require an
+explicit conflict assessment. A date or unrelated path cannot pass automatically.
+This assessment is offline agent evidence, not human review or native approval;
+the Action question schema and public runtime contract do not change.
+
+All eighteen actual ownership questions were read against the unchanged criterion,
+including the conflicting registered/requested owner and path. All nine retained
+trials were re-scored without new model queries or changed raw responses; counts
+in the table remain unchanged. An acceptable question never rescues an invalid
+plan. Exact questions, assessor rationales and original file identities are in
+`quality/sdd/evidence/issue-856-ownership-assessments.json`. The new scorer's 29
+regressions pass with 100% lines/statements/branches/functions; post-finding full qualification passes 901 suites/17,678 tests with 35
+pre-existing skips plus 267 extension tests. All 27 modified coverable lines
+are covered without partials locally. New-head remote controls and official
+Codecov remain required before merge.
+
+
+A subsequent low-severity review identified an absent provider response reaching
+question access and response hashing after parsing had failed. The actual probe
+assessor now records invalid plans before attempting either operation. Its module
+can be imported for regression tests without executing a campaign. Eleven tests
+exercise undefined, null, primitive, malformed and array responses plus valid
+object/string tuples and the explicit semantic assessment path. A replay of all
+nine retained trials preserves every earlier metric and raw file without new
+model calls. No missing response occurred in those historical trials; this is
+separate failure-handling evidence. Full validation of this correction passes 902 suites/17,689 tests with 35
+pre-existing skips and 267 extension tests. All 27 modified coverable runtime
+lines remain covered without partials locally. New-head native controls and
+official Codecov remain required.
