Public method explainer

Amnesiac spine

The Amnesiac spine demo shows a governed memory answer as an inspectable object rather than a model assertion. The public viewer displays admitted claims, shadow and refusal candidates, PacketWalk operations, PacketInspectionProjection summary, and SovereigntyReceipt artifact hashes for a synthetic NPV walkthrough.

Owner split

arcs-amnesiac

Owns the canonical walkthrough artifacts, static viewer generator, committed viewer HTML, tests, and source commit 42aeacf.

garp-showcase

Owns the product-facing demo route at /amnesiac/spine and the direct static viewer path at /amnesiac-spine-viewer/index.html. Its guard pins the copied viewer by SHA-256.

garpedia_org

Owns this public method explainer and the agent-readable claim boundary. It does not host the canonical artifact source.

garp-workbench

Remains the future operator surface if the walkthrough needs an internal cockpit. This page does not stand in for that cockpit.

Product paths

• /amnesiac/spine is the product-facing showcase page.
• /amnesiac-spine-viewer/index.html is the direct static viewer path.
• 42aeacf is the pinned arcs-amnesiac source commit.
• 0c819b2 is the garp-showcase explicit index-path fix commit.

Authorship boundary

The walkthrough keeps three roles separate. A model, source, or operator proposes candidate material. Admission ratifies or rejects each candidate. Deterministic rendering produces the Answer View from what admission ratified.

In this walkthrough, the Answer View is a deterministic rendering of admitted PacketWalk output. The model may propose candidate material, but it does not author the rendered answer. Rejected candidates stay recorded as rejected and are never admitted into the rendered answer.

Pinned provenance

Every value below is rendered from the generated engine-layer provenance module, not hand-copied into this page. The projection consumes the canonical walkthrough artifacts at exactly this source commit.

Regeneration and verification

Regenerate the projection with tsx scripts/exportAmnesiacWalkthroughToGarpedia.mjs against the pinned source checkout; verify it with node scripts/check-anatomy-of-a-claim.mjs, which recomputes the artifact hashes from source bytes.

Walkthrough conformance evidence

The frozen Amnesiac Spine walkthrough artifacts at the pinned source commit passed the checks evaluated by amnesiac_spine_conformance_pack.v0_1 (version 0.1.0), as recorded in its committed expected report. Items the report did not evaluate stay visible below with their report-recorded reasons. Every value in this section renders from the generated conformance fixture, never hand-copied.

Evaluated items

• AC-01 — Deterministic render of the pinned viewer — PASS
• AC-02 — Regeneration reproducibility of the canonical artifact set — PASS
• AC-03 — Admission-ratification coverage of the rendered surface — PASS
• AC-04 — Rejection lifecycle integrity — PASS
• AC-06 — Status-vector coherence (represented snapshots only) — PASS

Not evaluated

• AC-05 — Three-actor attribution — declared NOT_DECLARED, carried no verified status in the report, and is counted in the report’s not-evaluated total. Report-recorded reason: the frozen artifacts expose machine-readable actor fields for the operator only (operator_user_context.operator_ref, operator_user_context.auth_context_ref); builder identity appears only in trace.md prose and packet verifier identity is not present in the committed artifacts, and this pack does not infer actor identity from prose

Source-commit binding

The pack deferred AC-07 (Packet-time projection pin) to this surface. The walkthrough source commit pinned by this page’s engine-layer provenance, 42aeacf, equals the source commit the pack evaluated, 42aeacf. The equality is machine-checked by node scripts/check-amnesiac-conformance-projection.mjs.

Report identity

afe40bf1-9fbf-5193-94ac-bd2d4a0916e7 (report version 0.1)

This is walkthrough-scoped evidence. It is not Core Profile or corpus-level conformance and does not establish external authenticity or producer identity. The report itself records what it does not establish:

• Does not establish Core Profile conformance.
• Does not establish corpus-level conformance.
• Does not establish external authenticity.
• Does not establish producer identity.
• Does not establish real-world truth.
• Does not establish live enforcement.
• Does not establish coherent-rewrite detection without an external anchor.

Regenerate this projection with node scripts/exportAmnesiacConformanceToGarpedia.mjs against the exact pinned pack commit; the values above are read from committed Git objects, not from a checkout working tree.

Durable non-claims

• Amnesiac spine is not a model call.
• Amnesiac spine is not live retrieval.
• Amnesiac spine is not admission by GARPedia.
• Amnesiac spine is not private corpus rendering.
• GARPedia is not the source of truth.
• This page does not embed the viewer.
• This page does not regenerate canonical artifacts.
• This page does not claim a receipt chain.
