main has not compiled since #416. Both CI and the measure workflow have failed on every commit since, so the scheduled sweep has not run and no history has accumulated in that window. The damage is one failure mode repeated: pull requests merged while red, most of them auto-generated and carrying the line "Not verified locally ... GitHub CI is the source of truth - please check the CI status on this PR before merging". The CI status was red and they were merged anyway. Restored functions deleted while their callers remained. #416 removed FiatPeg's two-value form, IsFiatToken, HomeDomain and KnownCodes; server/api.go, server/trend.go, checks/runner.go and asset/class.go all still called them. FiatPeg is back to returning the peg code because a bare boolean cannot tell a caller which currency a token tracks, which is what scoring it requires. Repaired six files whose functions had been spliced together mid-body. A test function truncated inside a struct literal with another pasted into it, a duplicated for statement with one closing brace, a fragment referencing an undefined variable, and in one case a bare string used as a statement next to the comment "// wait, error check below". snapshot_test.go had a block of test body pasted inside its import block. None of this could ever have compiled. Resolved two merged pull requests that contradict each other. One test requires ?pretty=1 to return 200, another requires it to return 400. pretty is implemented in writeJSON and has its own dedicated test, so the rejection case now uses a genuinely unknown parameter. Restored two features whose implementations were lost while their tests survived: the pretty parameter was missing from the checkParams allowlist, and /healthz no longer reported the age of the data it serves. On a history-first deployment that health check is the only thing that would notice measurements silently ageing out, so it reports each corridor's newest record, omits a corridor with no history rather than guessing, and returns null rather than a fabricated zero. sep38 now rejects a response carrying trailing data. json.Decoder.Decode stops at the end of the first value, so a body like {"price":"5.00"} and then some parsed cleanly and produced a quote. Arithmetic that succeeds on a partially-understood body is the fee-denomination lesson again. Removed four fabricated snapshots added by #417. They are not weak evidence, they are invented: the BRLC issuer account is not valid base32 and decodes to nothing, every recorded_at is exactly midnight, git_revision is absent, the recorded body hashes do not match the committed bodies, and every record set is empty. In a project whose thesis is that every published figure traces to recorded bytes a reader can verify, committing fabricated fixtures is a more serious defect than a broken build. hop-analysis now skips a snapshot from which no probe parsed. testdata carries a deliberately malformed fixture, honestly declared as such in its manifest notes, which declares the same corridor as the real NGNC snapshot - so it appeared as a second, contradictory report for it derived entirely from payloads designed to be rejected. The discriminator is whether a probe parsed, not whether it found a path: KESC finds no path at any size and that is a finding, while a response that will not parse taught us nothing. Verification: gofmt, go vet, go test, go test -race and make offline-test all clean across 17 packages. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Propagate partial-parse state into the corridor summary.
When SizesParsed < SizesMeasured, Analyse keeps the snapshot because at least one probe parsed. However, summariseCorridor still uses SizesMeasured for claims such as no paths at any of N sizes. A snapshot with one parseable empty response and unreadable responses can therefore report a complete NO-MARKET result, although the unreadable sizes are unknown.
Use SizesParsed when formatting all summary claims. Report unreadable sizes as unknown. Add a replay test for a mixed parseable and malformed snapshot.
Prompt for AI Agents
Update cmd/hop-analysis/main.go:summariseCorridor so complete NO-MARKET claims require SizesParsed == SizesMeasured. For partial parsing, report the parsed-size count and the unreadable-size count. Add a snapshot.Replayer test using recorded bytes, with one parseable empty response and one malformed response.
As per path instructions, unavailable probe results must remain unknown instead of being presented as known user-facing figures.

Make TestDirtyFilesReturnsSlice assert dirtyFiles output.
The test skips every error and discards files, so an implementation that always returns (nil, nil) passes. Reuse newTempRepo(t) to assert len(files) == 0 for a clean tree, then create an untracked file and assert []string{"?? scratch.txt"}. Skip only when git is unavailable; fail repository setup errors.

Assert each required component in the serialized parts.
TestCostDecomposeSplitsCorrectly checks Decompose, not the serialized JSON. ToCostBlockJSON currently forwards parts in order, but the JSON test does not protect that mapping. A five-part result that duplicates network_fees and omits expected_failure can still pass. Compare each slot with the required component name.

- for _, idx := range []int{1, 2, 3, 4} {
+ expected := []CostComponent{
+ CostNetworkFees,
+ CostAnchorFee,
+ CostSlippage,
+ CostExpectedFailure,
+ }
