### Tool changes

- 2026-10-12 `assetfare_v2_quote_selected_candidate` changed (inputSchema)
- 2026-10-12 `assetfare_v2_route_selection` changed (description, inputSchema, outputSchema)
  - before: Quote the recent top two plus the best AssetFare graph at the exact amount; return up to two all-in choices labeled assetfare_verified_unsigned or external_provider_handoff. AssetFare cost, ETA and rank are always present; a recent winning range needs two supporting higher buckets and disappears on conflict. Example: compare Solana USDC to Base USDC at USD 347.25 with balanced (60s). Fast is 30s; economy is explicit up to 1,800s. Slower routes are reference-only. Never approves, prepares, signs, or submits.
  - after: Quote the recent top two plus the best AssetFare graph at the exact amount; return up to two all-in choices labeled assetfare_verified_unsigned or external_provider_handoff. AssetFare cost, ETA and rank are always present; a recent winning range needs two supporting higher buckets and disappears on conflict. Example: compare Solana USDC to Base USDC at USD 347.25 with balanced (60s). Fast is 30s; balanced and explicit economy are 60s. The 60-second ceiling is absolute for recommendations; slower routes are reference-only. Never approves, prepares, signs, or submits.
- 2026-10-12 `assetfare_v2_prepare` changed (outputSchema)
- 2026-10-12 `assetfare_v2_quote_selected_candidate` changed (description, outputSchema) **meaning changed**
  - before: Return the chosen candidate's exact request-time quote without another provider call while it remains valid. If it expired, refresh only that candidate at the same amount and never silently reselect. Example: pass the chosen candidate_id and exact selection receipt hash. AssetFare quotes retain continuation_v3; external quotes contain normalized facts and a provider handoff without executable payloads. This tool never prepares, signs, submits, or creates transaction authority.
  - after: Reuse the chosen exact request-time quote while valid; after expiry refresh only that candidate at the same amount and never reselect. Example: pass candidate_id and the selection receipt hash. An AssetFare result requires a caller-local proof check and fresh wallet simulation before verified_for_signing; remote verification is not signing authority. An external result is only its provider handoff and has no AssetFare transaction-verification claim. Never prepares, signs, submits, or grants transaction authority.
- 2026-10-12 `assetfare_v2_route_selection` changed (description, outputSchema)
  - before: Quote the recent top two plus the best AssetFare direct graph at the caller's exact amount and return up to two all-in recommendations. Always reports AssetFare's exact cost, ETA and rank. A non-guaranteed recent amount range appears only with two supporting higher buckets and disappears if the exact quote conflicts. Example: compare Solana USDC to Base USDC at USD 347.25 with balanced (60 seconds). Fast uses 30 seconds; economy is explicit up to 1,800 seconds. Slower routes are reference-only. This never approves execution, prepares, signs, or submits.
  - after: Quote the recent top two plus the best AssetFare graph at the exact amount; return up to two all-in choices labeled assetfare_verified_unsigned or external_provider_handoff. AssetFare cost, ETA and rank are always present; a recent winning range needs two supporting higher buckets and disappears on conflict. Example: compare Solana USDC to Base USDC at USD 347.25 with balanced (60s). Fast is 30s; economy is explicit up to 1,800s. Slower routes are reference-only. Never approves, prepares, signs, or submits.
- 2026-10-11 `assetfare_v2_quote_selected_candidate` changed (outputSchema)
- 2026-10-11 `assetfare_v2_route_selection` changed (description, outputSchema)
  - before: Use recent multi-amount exploration only to shortlist three candidates, quote all three at the caller's actual requested amount, and return up to two fresh complete all-in recommendations. Example: compare Solana USDC to Base USDC at USD 347.25 with the balanced 60-second profile. Fast uses 30 seconds and economy is explicit up to 1,800 seconds; slower candidates are reference-only. The result is not execution approval and never prepares, signs, or submits.
  - after: Quote the recent top two plus the best AssetFare direct graph at the caller's exact amount and return up to two all-in recommendations. Always reports AssetFare's exact cost, ETA and rank. A non-guaranteed recent amount range appears only with two supporting higher buckets and disappears if the exact quote conflicts.

## Packages

## Tools (11)

- `assetfare_manifest`: Read the Ed25519-signed release manifest and safety-bundle binding before preparing an action. Example: call this once to verify the current release and contract pins; it never creates state, signs, or submits.
- `assetfare_v2_capabilities`: Read all 100 technically available routes, live provider readiness, route-specific guidance, direct_route_summary, and continuation_v3 contracts before quoting. Forty-four routes are price-recommended only at or above their published threshold; 56 have no current price recommendation. Example: call once before requesting an exact route quote. Confirm every fresh quote. Economic guidance is advisory and never adds an execution gate. continuation_v3 separately binds execution selection, wallets, bounds, and mode. Read-only; creates no wallet login, session, or action.
- `assetfare_v2_prepare`: Return one deeply verified first unsigned bundle and caller-wallet handoff. Example: pass caller_approved=true, a one_shot approval_v3, and the quote-bound verification_context; multi-step routes reject one_shot. Economic guidance is advisory and adds no request field. Context is validated before the upstream request and never forwarded. AssetFare never signs or submits.
- `assetfare_v2_quote`: Get one fresh AssetFare quote with amount-specific economic_guidance, direct_route_summary, continuation_v3, and unsigned_prepare_requirements. Example: quote Solana USDC to Base USDC. price_recommended_for_amount is advisory; compare alternatives when price matters, but no economic acknowledgement field is required. The quote remains an unranked_candidate until separate explicit approval selects one mode. The adapter validates hashes, path, bounds, and TTL and never creates approval, prepares, signs, or submits.
- `assetfare_v2_quote_selected_candidate`: Reuse the chosen exact request-time quote while valid; after expiry refresh only that candidate at the same amount and never reselect. Example: pass candidate_id and the selection receipt hash. An AssetFare result requires a caller-local proof check and fresh wallet simulation before verified_for_signing; remote verification is not signing authority. An external result is only its provider handoff and has no AssetFare transaction-verification claim. Never prepares, signs, submits, or grants transaction authority.
- `assetfare_v2_route_selection`: Quote the recent top two plus the best AssetFare graph at the exact amount; return up to two all-in choices labeled assetfare_verified_unsigned or external_provider_handoff. AssetFare cost, ETA and rank are always present; a recent winning range needs two supporting higher buckets and disappears on conflict. Example: compare Solana USDC to Base USDC at USD 347.25 with balanced (60s). Fast is 30s; balanced and explicit economy are 60s. The 60-second ceiling is absolute for recommendations; slower routes are reference-only. Never approves, prepares, signs, or submits.
- `assetfare_v2_session_create`: Create one receipt-driven workflow. Example: pass caller_approved=true, a session approval_v3, its idempotency_key, a caller-local session token, and the quote-bound verification_context. Economic guidance is advisory and adds no request field. The adapter validates approval and context before the upstream request. Every returned action is deeply verified and receives a caller-wallet handoff. AssetFare never signs or submits.
- `assetfare_v2_session_get`: Read an existing v2 workflow without advancing it. Example: pass session_id, session_token, and the original verification_context after restart. The adapter deeply verifies any current_action and emits a self-verifying wallet handoff, or fails closed. Read-only; never signs or submits.
- `assetfare_v2_session_observe_output`: Record an already-produced bridge or destination output, then advance the workflow. Example: pass the output hash, a new idempotency key, and the original verification_context. Any next current_action is deeply verified and receives a wallet handoff. AssetFare never signs or submits.
- `assetfare_v2_session_observe_source`: Record source hashes the caller already signed and submitted, then advance the workflow. Example: pass one finalized source hash, a new idempotency key, and the original verification_context. Any next current_action is deeply verified and receives a wallet handoff. AssetFare never signs or submits.
- `assetfare_v2_session_refresh_action`: Refresh an expired action only while it remains unsubmitted. Example: pass the existing session, a new idempotency key, and the original verification_context. The refreshed action is deeply verified and receives a wallet handoff. Never refresh a submitted step; AssetFare never signs or submits.
