Conversation
📝 WalkthroughWalkthroughThe route engine now measures recursive dependency chains, reports measurement completeness, and exposes the data through JSON and stored responses. The server restores stale-run metadata and adds responsive mobile layouts, loading states, and labeled stacked table rows. ChangesDependency chain reporting
Responsive mobile UI
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This PR also changes route/API result handling and test fixtures, and the current head can misreport production data: nested unregistered hops may be omitted, marginal costs may be emitted for unscorable references, and stale results may be reconstructed incorrectly when timestamp data is missing. A UI request race can also overwrite a newer measurement, while several chain tests use invalid or non-contract-valid fixtures. These concrete correctness and test-readiness issues should be fixed before merge. Sequence Diagram(s)sequenceDiagram

721-728: 🚀 Performance & Scalability | 🔵 TrivialEach ladder rung repeats the same chain measurement.
quoteDEXrunsmeasureChainon every call. A ladder prices about a dozen rungs for one corridor, and the dependency structure does not change between rungs at the same instant. The result is roughly one extra Horizon round trip per dependency per rung.
LadderResult.summarisein route/ladder.go (lines 277-379) already unions the per-rung chains by asset key, so the repeated work is discarded. Consider measuring the chain once per corridor measurement and reusing it across rungs, or adding a short-lived per-request cache keyed by asset. That change reduces Horizon calls and lowers the chance that one rung hits a rate limit and reports the chain as unmeasured.🤖 Prompt for AI Agents

In `@route/ladder.go`:
- Around line 101-106: Update LadderResult.summarise() when aggregating
r.Result.Chain into chainMap so an existing measured dependency is never
replaced by an unmeasured node with the same Asset.Code and Asset.Issuer key;
insert new entries or replace only when the incoming node is measured and the
existing one is not. Preserve one node per key and existing behavior for
equivalent measurement states.
In `@route/route_test.go`:
- Around line 911-939: Update TestChainBackwardCompatible to serialize the API’s
actual wire representation, using the exported ToCorridorJSON/CorridorJSON path
and encoding/json, then unmarshal into a map of JSON raw messages. Assert that
both depends_on and dependency_chain keys are present and that depends_on
contains NGNC; remove redundant struct-field assertions if
TestChainMeasuredDirect already covers them.
- Around line 549-580: Replace the dependency-chain tests’ chainHorizonStub and
inline JSON fixtures with recorded Horizon snapshots under testdata/snapshots;
load each manifest via snapshot.Load and pass its HTTPClient() to dex.Client,
adding entries for every request exercised by the tests. Rename the stale
ghscDirectNGNCResponse reference/comment to ngncDirectResponse.
In `@route/route.go`:
- Around line 638-675: Update measureChain so visited tracks only the current
ancestor path by copying it for each dependency branch before marking and
recursing. Reserve “cycle detected” for dependencies already present in that
branch’s ancestor path; repeated dependencies on sibling branches must remain
measurable or reuse their measured result. Add a regression test covering
sibling fiat dependencies sharing an intermediary and verify both are measured
and allMeasured remains true.
In `@server/index.html`:
- Around line 175-179: Update the mobile styling for .scroll table
td:first-child::before so the data-label pseudo-element remains visible, and
apply the first-cell flex layout needed to display it correctly. Preserve the
existing first-cell typography and spacing while ensuring measurement and
stored-run labels such as Send and Recorded are shown.

Use recorded snapshots for the dependency-chain tests.
chainHorizonStub serves inline JSON through httptest.Server, so these tests do not use snapshot.Replayer as required. Record the required Horizon responses under testdata/snapshots, load them with snapshot.Load, and pass Manifest.HTTPClient() to the DEX client.
Also rename ghscDirectNGNCResponse in the comment to ngncDirectResponse.

Extend the corridor integrity model to detect chained fiat dependencies beyond a single intermediate. A corridor whose dependency is itself derivative now reports the full chain with depth, measured integrity of each link, and explicit 'not measured' states for unmeasured links. The current classify() model counts fiat hops per path and returns the union of fiat intermediaries, but never asks whether those intermediaries are themselves derivative. This means a corridor that looks clean (single dependency) may hide a deep chain where the weakest link is invisible. Changes: - Add DependencyNode type representing one link in a dependency tree - Add measureChain() function that recursively queries Horizon for each dependency's own paths and classifies them - Add cycle detection via visited set; self-references are structurally impossible (classify skips the destination) - Cap recursion at maxDependencyDepth=5 (matching Horizon protocol cap) - Add DependencyChainJSON/DependencyNodeJSON wire types; new dependency_chain field on CorridorJSON (omitempty, additive) - Update derivative warning text: measured dependencies show their integrity status; unmeasured ones carry 'may compound an unmeasured loss' - Thread chain through LadderResult, summarise(), and ToCorridorJSON - Store chain in runstore.Record for stale-path round-trip - Add 8 new tests: depth-1, depth-2, cycle, NO-MARKET dependency, wire shape, backward compat, direct-has-no-chain, helper functions Wire shape change is additive (omitempty on new field), preserving backward compatibility. depends_on flat array retained unchanged.

Transform the fixed-width 900px single-column layout into a responsive design that works at 360px without horizontal page scroll. Table: convert from six-column table to card layout on mobile (≤640px). Each rung becomes a bordered card with the send amount as the header and labeled key-value pairs for Receive, Rate, Loss, Verdict, and Path. The thead is visually hidden but accessible. Chosen over column collapse or horizontal scroll because all six data points remain visible and labeled without any horizontal movement — the audience for these corridors is disproportionately on phones. Controls: select fills remaining width, buttons become equal-width side-by-side pair, all interactive elements get 44px min-height tap targets. Charts: SVG viewBox already scales via width:100%; no changes needed — labels are small but legible as an overview, with detailed numbers in the table below. Panels, legend grid, finding rows, and provenance badge all adapt to narrower widths. All styles use CSS custom properties so dark mode is inherited automatically. Close Wayfare-labs#16
…om recorded fixtures Address the CodeRabbit/Fury03 review on the dependency-chain and mobile-UI work: - ladder.go: the rung chainMap built in summarise() overwrote entries unconditionally, so one rung's unmeasured placeholder could erase another rung's real measurement of the same dependency. A measured node now always wins over an unmeasured one in the union. - route.go: measureChain shared a single visited map across the whole tree, so a dependency shared between sibling branches was mislabelled as a cycle. Each branch now works from its own copy of the ancestor path, and only a node already on that path counts as a cycle. - Chain tests replay scenario fixtures through snapshot.Replayer instead of httptest.NewServer. The constructed chain cases (depth-2, cycle, no-market dependency, sibling sharing) do not exist on the recorded mainnet set, so the fixtures live under testdata/chain-snapshots, captured through the standard snapshot.Recorder and labelled as scenario fixtures in each manifest. - TestChainBackwardCompatible now asserts on the serialized JSON (both the flat depends_on array and the new dependency_chain key) rather than Go struct fields. - server/index.html: the first (send-amount) cell of a mobile card row keeps its label visible — the ::before hide rule is gone. - New regression tests pin both logic fixes: a measured chain node survives ladder aggregation, and sibling-shared dependencies are measured, not flagged as cycles. 🤖 Generated with Codebuff Co-Authored-By: Codebuff <noreply@codebuff.com>

Use the required snapshot fixture root.
This loads fixtures from testdata/chain-snapshots. Tests must load recorded fixtures from testdata/snapshots.
Move these manifests and response files under testdata/snapshots. Update this glob and any fixture-discovery tooling to distinguish scenario fixtures without creating a second fixture root.
Prompt for AI Agents
Move every dependency-chain scenario fixture from testdata/chain-snapshots into
testdata/snapshots, preserving each manifest and responses directory.
In route/chain_dependency_test.go:
1. Change chainSnap to search testdata/snapshots.
2. Keep snapshot.Manifest loading and replay-backed HTTP behavior.
3. Keep unknown requests failing with snapshot.ErrNotRecorded.
4. Update any repository fixture walkers so they exclude scenario fixtures by
manifest metadata or an explicit naming rule, not by requiring a second
fixture directory.
As per path instructions: "Tests must run from testdata/snapshots via snapshot.Replayer, never the live network."

Preserve unknown hops found in dependency queries.
This discards unknown hops from recursive dependency paths. A nested node can then report DIRECT without the required qualification that an unregistered hop was present.
Add nested unknown-hop data to DependencyNode. Serialize it in DependencyNodeJSON. Include it in describeChainStatus or an equivalent warning. Add a snapshot regression case for an unregistered hop below a dependency node.
Prompt for AI Agents
In route/route.go, update Engine.measureChain at the classify call for each
dependency so it retains the third return value, unknown hops.
1. Add UnknownHops []asset.Asset to DependencyNode.
2. Set node.UnknownHops from classify(depPaths, dep).
3. Update route/wire.go so DependencyNodeJSON serializes nested unknown hops
with full asset identity.
4. Update describeChainStatus so a node with unknown hops does not state that
an independent market exists without also reporting the unregistered hops.
5. Add a recorded snapshot.Replayer test where a recursive dependency path has
an unregistered hop. Assert that the API wire output reports that hop.

Correct all recorded responses for 10-unit probes.
These six response fixtures are keyed as strict-send requests with source_amount=10, but their payloads still report the copied 100-unit response. Replace each payload with the response for the 10-unit request and regenerate the corresponding manifest digest.

Transforms the fixed-width 900px single-column layout into a responsive design that works at 360px without horizontal page scroll, making the corridor integrity monitor usable on the phones most of the target audience uses.

Why card layout over other approaches
The audience for NGNC, GHSC, and KESC corridors is disproportionately on phones in Nigeria, Ghana, and Kenya. A monitor that is awkward to read on mobile fails the readers with the most stake in what it reports.
