Why: The Dev combination must pin the slice-2 commit; make test validates the fixed combination.
Evidence: modules/backend -> 1de663a8d3302eddbd35d8a1906e4234e17c28e8 (Backend PR #107).
Impact: Gitlink only.
Refs: Backend PR #107; task card.
Why: Slice 2 closes the knowledge-retrieval half of EXT-8 and lands the minimal EXT-12 mirror switch; scope and limits must be recorded before code.
Evidence: Search paths (sqlite/like/PG) verified to share the knowledgeVisible predicate; cardsvc.emitCard mirrors unconditionally.
Impact: Task card only.
Refs: EXT-8/EXT-12 proposals; prior task cards' deferred-items registry.
Why: establish the authorized task workspace and its initial baseline.
Evidence: preserved precheck receipt in .task/feature-ext8-slice2-shared-retrieval.md; R0=749f327986f30a953fb6723b6970c42738a572af.
Impact: task metadata only; the feature workspace starts at 749f327986.
Refs: .task/feature-ext8-slice2-shared-retrieval.md
Why: branches merged into main had left their task cards open; backfill status and archive to prevent bookkeeping debt.
Evidence: feature-ext-9-index-publish.md(PR#267) — merges verified via git log --merges against origin/main.
Impact: .task/*.md moved to .task/archive/ with status backfilled; no code or submodule change.
Refs: task.sh close (card-autoclose-r1)
Why: CI on PR HEAD is the authoritative gate before merge.
Evidence: Backend#106 success; Dev#267 success.
Impact: Task card only.
Refs: AGENTS.md evidence gate.
Why: The Dev combination must pin the EXT-9 commit; make test validates the fixed combination.
Evidence: modules/backend -> fbc924c24045f8a9e22fc4047982c23d09bcebf3 (Backend PR #106).
Impact: Gitlink only.
Refs: Backend PR #106; task card.
Why: EXT-9 is accepted (Documents #49) as the other step-4 hard prerequisite; the publish/revoke surface and the upload pre-index switch must be scoped before implementation.
Evidence: Knowledge store shapes verified (owner column, DeleteKnowledgeByRef, vectors-by-ref cleanup precedent).
Impact: Task card only.
Refs: EXT-9 proposal; U0 section 5 C5 / section 10 step 4.
Why: establish the authorized task workspace and its initial baseline.
Evidence: preserved precheck receipt in .task/feature-ext-9-index-publish.md; R0=7b73dd19b8566446c137a6e3a46fed17bfa548d4.
Impact: task metadata only; the feature workspace starts at 7b73dd19b8.
Refs: .task/feature-ext-9-index-publish.md
Why: branches merged into main had left their task cards open; backfill status and archive to prevent bookkeeping debt.
Evidence: feature-ext-8-resource-authorizer.md(PR#265) — merges verified via git log --merges against origin/main.
Impact: .task/*.md moved to .task/archive/ with status backfilled; no code or submodule change.
Refs: task.sh close (card-autoclose-r1)
Why: CI on PR HEAD is the authoritative gate before merge.
Evidence: Backend#105 success; Dev#265 success (polled pending->success).
Impact: Task card only.
Refs: AGENTS.md evidence gate.
Why: The Dev combination must pin the EXT-8 commit; make test validates the fixed combination (which also carries the audit fix via stacking).
Evidence: modules/backend -> a4783d18e7156e4f48188e6816be865ed82380f6 (Backend PR #105, stacked on #104).
Impact: Gitlink only; other pins unchanged.
Refs: Backend PR #105; task card.
Why: Red run must be tool-pinned to the backend commit before the consultation lands.
Evidence: Row exit=1 at backend tip (shared read 404 with adapter set).
Impact: Task card only.
Refs: Task card.
Why: EXT-8 is accepted (Documents #49) and is the U0 step-4 critical path; the backend branch stacks on the audit-fix head (parent PR #104) to avoid a second gitlink conflict.
Evidence: Documents #49 and Dev #263 merged this session; parent head e0b1c27 pushed.
Impact: Task card only.
Refs: EXT proposal EXT-8; U0 section 5 C4 / section 10 step 4.
Why: establish the authorized task workspace and its initial baseline.
Evidence: preserved precheck receipt in .task/feature-ext-8-resource-authorizer.md; R0=27885ceb3e6c774495b61e07f560efa1a51855fc.

Refs: .task/feature-ext-8-resource-authorizer.md
Why: branches merged into main had left their task cards open; backfill status and archive to prevent bookkeeping debt.
Evidence: feature-ext-c1-c7-applications.md(PR#263) — merges verified via git log --merges against origin/main.
Impact: .task/*.md moved to .task/archive/ with status backfilled; no code or submodule change.
Refs: task.sh close (card-autoclose-r1)
Why: CI on PR HEAD is the authoritative gate; Documents has no CI runner (docs-only repo, 0 statuses) which must be stated, not implied.
Evidence: Documents#49 no statuses; Dev#263 ci/test success.
Impact: Task card only.
Refs: AGENTS.md evidence gate.
Why: Closing outputs plus honest SELF/GATE boundary on the card.
Evidence: task-sync exit=0; make test exit=0 at tip 9bdec04.
Impact: Task card only.
Refs: Task card.
Why: Composition validation at the new documents pin is the Dev-side gate.
Evidence: make test exit=0 (governance + pins + module suites at documents 9995552).
Impact: Task card only.
Refs: Task card.
Why: The Dev combination must pin the proposal commit; make test validates the fixed combination (adopting Documents main 4e57196 plus the new proposal and INDEX row).
Evidence: modules/documents -> 9995552152616bfaf6473cd9249e55a28a1685b4 (Documents PR #49); make test row follows.
Impact: Gitlink only; other pins unchanged.
