+## Intake
+
+| Field | Value |
+| --- | --- |
+| Source / trigger | [dapi/memory-bank#87](https://github.com/dapi/memory-bank/issues/87) |
+| Research owner | delivery orchestrator |
+| Decision owner | `dapi/memory-bank` maintainer |
+| Research mode | `technical_discovery` |
+| Decision deadline / timebox | Bounded desk research completed 2026-08-05 |
+
+## Decision Question
+
+- `RQ-01` Does the current repository still contain validation implementation
+  that should be removed or moved to `dapi/memory-bank-cli`, and is a new
+  standalone CLI task required?
+
+## Working Hypotheses
+
+- `HYP-01` Reusable `lint` and `doctor` validation is already owned by
+  `dapi/memory-bank-cli`; the remaining Ruby checks in this repository are
+  producer-side integration checks and should remain here.
+
+## Compact Method Record
+
+- Method and source strategy: inspect the issue and maintainer routing record,
+  the migration commit, the current CI workflow and the linked CLI migration
+  issue.
+- Collection window and context: GitHub and the checked-out repository on
+  2026-08-05; current `main` at `23ff0a3905645c6f4e37809ae7e97d43cb937a37`.
+- Evidence-quality criteria: primary GitHub issue/commit/workflow sources;
+  distinguish current executable use from historical intent.
+- Applicable privacy, consent, legal, security and vendor-access constraints:
+  none; only public repository metadata and checked-out source are used.
+- Bias risk and disconfirming signal: prior maintainer conclusions could be
+  stale; current CI still invoking local reusable lint/doctor implementation
+  would contradict `HYP-01`.
+
+## Scope
+
+- `RSC-01` Ownership of validation used by this repository's CI and remaining
+  `tools/` scripts, relative to `memory-bank-cli`.
+
+## Non-Scope
+
+- `RNS-01` Changing CLI behavior, release process, or template CI contracts.
+- `RNS-02` Deleting repository-specific checks without a separately routed
+  delivery task.
+
+## Assumptions and Known Evidence
+
+| ID | Statement | Type | Source / confidence |
+| --- | --- | --- |
+| `ASM-01` | The issue seeks a decision before any deletion or new CLI work. | Evidence | [Issue #87](https://github.com/dapi/memory-bank/issues/87) |
+| `ASM-02` | The maintainer is the decision owner for this repository decision. | Evidence | [Routing comment](https://github.com/dapi/memory-bank/issues/87#issuecomment-5087962973) |
+
+## Stopping Condition
+
+- `STOP-01` Stop once the migration history, current CI ownership boundary and
+  linked CLI migration task either support or refute `HYP-01`.
+
+## Open Questions
+
+| Question | Blocks | Owner | Resolution evidence |
+| --- | --- | --- | --- |
+| None | — | — | `STOP-01` is satisfied. |
+
+## Boundary Check
+
+- [x] This brief contains a question and hypothesis, not findings presented as facts.
+- [x] Every known fact has a clickable source link.
+- [x] No committed delivery scope, selected solution, ADR decision or implementation sequence is defined here.
+- [x] Required privacy, consent, legal, security and access constraints are explicitly `none`.

+
+## Decision
+
+| Field | Value |
+| --- | --- |
+| Decision owner | `dapi/memory-bank` maintainer |
+| Decision date | 2026-08-05 |
+| Decision reference | [Issue #87 validated decision comment](https://github.com/dapi/memory-bank/issues/87#issuecomment-5187546909) and this evidence package |
+
+Terminal disposition is recorded only in sibling `brief.md` as
+`research_status: validated`.
+
+## Decision Rationale
+
+- `FND-01` and `FND-02` show a clean ownership boundary: reusable validation
+  is in the standalone CLI, while the remaining Ruby scripts are local
+  producer-side integration validation.
+- `FND-03` confirms that the task which performed the CLI migration is closed;
+  no new reusable CLI requirement is evidenced here.
+- `LIM-01` means this is not an assertion that the Ruby checks must remain
+  forever; it rejects deletion or a duplicate CLI task on the present evidence.
+
+## Recommendation
+
+- `REC-01` Retain `tools/validate-priming-manifests*.rb`, create no duplicate
+  `memory-bank-cli` issue, and record the ownership decision in this completed
+  research package. Confidence: high for ownership; see `LIM-01` for the
+  boundary of the conclusion.
+
+## Alternatives Considered
+
+| Alternative | Why not selected / what would change the decision |
+| --- | --- |
+| Delete remaining `tools/` scripts now. | Rejected: current CI invokes them as a distinct producer-side integration surface; a separately routed removal/change would need evidence that this coverage is obsolete. |
+| Create a new CLI issue. | Rejected: CLI migration is already closed and this research identifies no missing reusable CLI contract. A concrete reusable requirement would justify new Task Routing. |
+
+## Promotion and Handoff Map
+
+| ID | Accepted or retained fact | Canonical downstream owner | Target route / link |
+| --- | --- | --- | --- |
+| `HD-01` | The current Ruby priming-manifest checks remain repository-specific integration validation. | This package's retained decision record; no new active project fact is required. | No follow-up delivery route. |
+| `HD-02` | Future extraction requires a concrete reusable CLI contract. | A new issue owned by the requester. | New [Task Routing](../../flows/routing.md) only if that requirement appears. |
+
+## Closure Check
+
+- [x] Sibling `brief.md` records matching terminal `research_status: validated`.
+- [x] `synthesis.md` answers `RQ-01`, and this recommendation traces to `FND-*` and `LIM-*`.
+- [x] Handoff creates neither delivery scope nor implementation steps by implication.

+| `OBS-02` | Current CI installs `memory-bank-cli` for `lint` and `doctor`, but runs `ruby tools/validate-priming-manifests*.rb` separately before those CLI commands. | [SRC-04](#sources) | `RQ-01`, `HYP-01` | Shows execution ownership, not whether the Ruby checks are useful. |
+| `OBS-03` | The linked CLI task is closed and defined the move to a standalone `memory-bank-cli` with preserved `lint` and `doctor` semantics. | [SRC-05](#sources) | `RQ-01`, `HYP-01` | Does not establish a new CLI feature is impossible. |
+| `OBS-04` | Current `main` CI completed successfully for the examined integration workflow. | [SRC-06](#sources) | `RQ-01` | A passing run does not independently establish completeness. |

+## Findings
+
+| ID | Finding | Evidence | Confidence | Implication for `RQ-*` / `HYP-*` |
+| --- | --- | --- | --- | --- |
+| `FND-01` | Reusable `lint` and `doctor` implementation was moved out of this repository into `memory-bank-cli`. | [OBS-01](evidence.md#observations), [OBS-03](evidence.md#observations) | High | Supports `HYP-01`; no local Go CLI remains to remove. |
+| `FND-02` | Remaining Ruby priming-manifest checks are an explicit repository CI surface run alongside, not through, the installed CLI. | [OBS-02](evidence.md#observations) | High | Supports retaining the checks under this repository's ownership. |
+| `FND-03` | The migration task that established the standalone CLI is already completed, and current main CI is green. | [OBS-03](evidence.md#observations), [OBS-04](evidence.md#observations) | Medium | Does not justify a duplicate CLI issue without a new CLI requirement. |
+
+## Limitations and Disconfirming Evidence
+
+| ID | Limitation / conflicting signal | Effect on conclusion | Mitigation or next question |
+| --- | --- | --- | --- |
+| `LIM-01` | This is a bounded source review, not a semantic redesign of the Ruby validation. | The recommendation does not claim the scripts can never move. | Route a new technical discovery or delivery issue only if a concrete reusable CLI contract is proposed. |
+| `LIM-02` | Green CI proves execution on current main, not every possible regression case. | Confidence in ownership is unaffected; coverage adequacy remains outside this issue. | Evaluate coverage independently if a future issue identifies a gap. |
+
+## Answer to Decision Question
+
+No additional removal is supported. The reusable validation requested by the
+issue is already in `dapi/memory-bank-cli`; the remaining Ruby checks validate
+this repository's priming-manifest producer and CI integration. A new CLI task
+would duplicate completed migration work unless a separate requirement defines
+a reusable CLI contract for those checks.
+
+## Review Check
+
+- [x] Every finding traces through linked observations to linked sources.
+- [x] Confidence reflects source quality rather than the desired outcome.
+- [x] Alternative explanation and residual uncertainty are visible.
