🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Align the missing-messageId rule with Section 4.
Lines 34-35 say that a correlating consumer cannot accept a record without messageId. Lines 131-145 say that the reference behavior correlates two id-less records and that the specification is ambiguous. Limit the refusal claim to consumers that require messageId, then define the intended id-less correlation rule separately.
Proposed wording
-The same applies to a record with no `messageId`: correlation is undefined for
-it, so a consumer that correlates cannot honestly accept it.
+A record with no `messageId` may be unusable for consumers that require
+message-ID correlation. The specification must also define whether two id-less
+records correlate; the reference consumer currently treats them as matching.📝 Committable suggestion

… library Reading the interchange format is not specific to this suite, and the format has a second consumer already: @ocpp-debugkit/toolkit parses the same records. So `trace-format/` is now a library destined for the open-ocpp-trace organisation, and `tck/trace.ts` is what is genuinely local -- which of the library's facts are worth refusing a run over, and how a record becomes one of ocpp.ts's frames. Two rules make it usable by both consumers, and they are the whole design: - No domain model. It returns validated records and the normative consumer view; the caller maps those onto whatever it already has. This suite has `Frame`, a debugger has timeline events, and a third model would tax both. - No error policy. A diagnostic states a fact and carries no severity, because the two consumers give opposite answers: this suite refuses a whole file rather than judge a run on frames it is unsure of, a debugging UI shows what it can. Encoding either would make the other wrong, silently. The corollary is load-bearing: a record that satisfies the schema produces NO diagnostic, however unusable a given consumer finds it. `raw` is optional in the schema, so a producer emitting only `payload` is conformant -- and this runner still cannot judge on it, because its assertions read frames made from bytes. That refusal is now named `payload-only`, apart from `unreadable`, because the two are different news and the runner says different things about them. The format's conformance rules have no word for "valid but unusable for my purpose"; this is that word, spelled locally, and it is worth taking upstream. Detection moves, policy stays. The library reports a `raw` that disagrees with its envelope on every member; this suite still refuses over three of them -- messageType, messageId, action -- because a disagreement there silently answers the wrong question, where one on a merely reported member shows up in the failure detail a human is already reading. Verified against the document rather than against our opinion of it: tools/trace-conformance.sh (network, out of gate) runs the reader over the specification's 16 fixtures at a pinned ref and reproduces every expected.json exactly. And over this repository's own archived corpus -- 94 traces, 1580 records from run 32186123642 -- every record reads clean and every trace is frame-for-frame identical to what parseLog gets from its log, which is the substrate-agreement property the runner is built on. tests/trace-format-standalone.sh is what keeps the extraction real: one import of ../tck/ would turn the library back into an internal module while every other check here stayed green.
findResponseFor scanned forward from a CALL and returned the first response with a matching uniqueId and reply direction. The format this suite now reads its frames from states the rule from the other side: a response correlates with "the most recent preceding CALL" that has the same messageId, travels in the opposite direction, and "is not already correlated with an earlier response". The two agree while ids are unique -- and diverge on a reused one, where a forward scan hands two calls the same response and the rule pairs them one to one. That was until now an internal quirk. It is not any more: trace-format/ derives the format's consumer view with the normative rule, so leaving this alone would mean tools/trace-conformance.sh proves the library agrees with the specification while the assertions quietly do not. The suite reads one wire two ways; correlating it two ways is the divergence a single reading exists to prevent. Measured before and after over every archived trace this repository has -- 94 traces, 791 CALLs from run 32186123642 -- not one duplicated call id and not one pairing difference. So this changes no verdict today and is only right about the case that has never occurred. tests/spec-invariants.sh confirms: no scenario's assertions or call sequence moved. The guard earned this the hard way. The row for the not-already-answered clause went red as intended; the one for opposite-direction stayed GREEN, because a fixture where every CALL travels one way and every response the other cannot tell the clause from a no-op. The second block builds the shape that bites -- the CSMS opening a call that reuses an id the charge point has outstanding, so the nearer candidate is the wrong-direction one. tck/ocpp.ts moves upstream-verbatim -> upstream-patched, with the NOTICE line that change obliges. BREAKING CHANGE: findResponseFor no longer searches from index 0 when the CALL is absent from the frames it was handed. A call with no position in the array cannot anchor "most recent preceding", so it now returns undefined instead of correlating against a wire the call is not on. Every caller in this repository passes a frame from the same array.
…lf-check Three things a review turned up. validateRecords could return an unexplained hole. It skipped `undefined` entries silently, so that readTraceText would not report a line as "not an object" when what happened is that it was not JSON at all. That made the library's own contract -- a record is withheld if and only if something says why -- false at its exported entry point. Harmless to a caller that refuses on any hole, and exactly wrong for the other kind: a UI that shows what it can and annotates the rest would have dropped a record with nothing to annotate, which is the failure mode this library's no-policy rule exists to prevent. The suppression now lives in readTraceText, which is the only caller that HAS the earlier diagnostic and so the only one entitled to drop the second. conformance.ts is the corpus self-check, expressed over this reader. It is meant to replace conformance/validate.mjs upstream, which compiles the schema with ajv and open-codes buildConsumerView -- so the document's CI currently proves its fixtures self-consistent rather than proving any shipped reader correct. Two implementations of a normative rule is what a conformance corpus exists to prevent, one level up. tools/trace-conformance.ts now runs that instead of its own copy, so what CI here checks is what would ship there. readTraceText moves to read.ts so conformance.ts can reach it without the barrel importing something it exports. SPEC-FEEDBACK.md collects what needs spec TEXT rather than code: that the format has no word for "valid, but unusable for my purpose" -- the distinction this library's whole API shape stands in for; that `raw` being optional silently splits consumers into those that read bytes and those that read payload, with no fixture covering the case; and that the correlation rule's "not already correlated" and "opposite direction" clauses are both unobservable in the corpus, so an implementation can drop either and reproduce all 16 expected.json files. Both were caught here by mutation, not by the corpus -- and the second only after the first attempt at that guard passed with the clause removed.
… a case Cleanup pass over the extraction. Nothing here changes what a scenario measures; the archived corpus still reads frame-for-frame identical to its logs, and the specification's 16 fixtures still reproduce exactly. ONE CORRELATION RULE. findResponseFor open-coded the same three clauses consumerView already implemented, so the rule this repository had just adopted existed twice -- which is the thing tck/trace.ts argues against one layer up for parsers, and for the same reason: tools/trace-conformance.sh proves the LIBRARY reproduces the specification, and a second copy makes that proof say nothing about the assertions. trace-format/correlate.ts now owns it over a structural shape, consumerView and findResponseFor both call it, and ocpp.ts keeps only the adaptation from Frame to the format's vocabulary. Mutating the rule now turns both guards red, which is the property that was missing. NAME THE CLASS, NOT THE CASE. `payload-only` was a special case tested above recordToFrame while a missing `messageId` -- the identical fact, an optional member this runner needs -- fell through to `unreadable` and handed a conformant producer the runner's advice about broken mounts and stale images. recordToFrame now returns which kind of "no" it is, and `no-message-id` joins it. One special case is a bug waiting for its second instance; the second instance was already here. TWO POLICY ROWS THAT DECIDED NOTHING. refusesOver listed raw-not-json and raw-not-array, on the reasoning that saying so early "costs nothing". It cost something: neither can become a frame anyway, so deleting both left the guard green -- the mutation saying the table claimed two judgements it did not make. The rest, in one line each: conformance.ts is no longer re-exported from the barrel, because it reads directories and would put node:fs in the graph of the browser consumer this library exists to serve (it has its own entry now); RawEnvelopeMember closes the member half of the policy API, which was bare strings while the code half was a closed union; readTraceText keys off the hole itself rather than the reported indices, which is both simpler and safe against a future diagnostic that leaves no hole; formatDiagnostics is exported instead of rendered twice; FrameMapping and TraceRead are one parameterised type; and a `before` that was always 0, an identity `.map`, a doubled scan and a `(unknown | undefined)[]` that TypeScript collapses to `unknown[]` are gone. Left alone deliberately: the O(n^2)-per-lookup pairing, measured at 0.03 ms for this repository's largest scenario and 15 ms for the whole 94-trace archive against sweeps that take minutes -- the shape that states the rule beats the shape that saves the microseconds; and tweak() duplicated across the two guards, since tests/ has no shared module and self-contained guards are the house convention.
…k the UTC offset
Review findings, verified against the code and fixed where they still held.
THE BOUNDARY GUARD ALLOWED THE SPELLING IT EXISTS TO CATCH. Its filter was
`grep -vE '^(\./|node:)'`, which reads as "inward or built-in" and is not:
`./../tck/ocpp` starts with `./`, resolves straight out of trace-format/, and
passed. Same tie back to this repository as `../tck/ocpp`, silently permitted.
The check is on the resolved shape now -- a `..` segment is an offender
wherever it sits -- and the header says what "inward" means rather than
implying it from one example.
AN RFC 3339 OFFSET HAS RANGES. The regex accepted `[+-]\d{2}:\d{2}`, so
`+99:99` validated. `time-numoffset` is `time-hour ":" time-minute` in the
grammar, with the same bounds the clock has. Two rows pin it, plus four legal
offsets, because a validator that rejected every non-Z timestamp would satisfy
the first two on its own.
A CALL ABSENT FROM ITS FRAMES had no test, which is poor for the one behaviour
this branch declares as breaking. There is one now, with the control case
beside it. Worth recording how it was checked: the obvious mutation -- deleting
the `callIndex === -1` early return -- leaves it GREEN, because `findIndex`
never matches -1 either, so the code is right twice there. It goes red on the
regression it is actually for, replacing identity lookup with a structural one.
And property 8's list of refusal reasons had not grown `no-message-id` when the
refusal did.
SKIPPED, with reasons.
An `undefined` guard on `response.messageId` in correlate.ts: the reference
consumer compares `c.messageId === r.messageId` with no such guard, so two
id-less records correlate there and must here -- this library's job is to
reproduce it, and diverging would make the conformance run prove nothing. The
finding is real as a question, though, so it is now finding 4 in
SPEC-FEEDBACK.md: nothing in the document says which reading is intended, and
no fixture exercises it.
Duplicate station IDs in `resolveStations`, and the `process.exit()` paths in
the run-all/run argument parsing: both are pre-existing `tck/main.ts`
behaviour, visible only because `patches/tck/main.ts.patch` carries the whole
diff against upstream. Zero added lines in this branch touch either. They are
also a generated artifact, which is never hand-edited.
Review findings, verified against the code and fixed where they still held.
A DYNAMIC IMPORT WAS INVISIBLE TO THE GUARD. Its pattern demanded whitespace
between the keyword and the quote, which `import("../tck/ocpp")` does not have,
so it read every static import in the subtree and no lazy one. Same hole as the
`./../` spelling closed last round, in the other axis: a specifier the guard
cannot see is a specifier it permits, and a lazily-imported tie back to this
repository is exactly as fatal to the move as an eager one. Three mutations --
an outward dynamic import now rejected, an INWARD one still accepted so the fix
is not over-rejection, and `./../` still rejected.
SPEC-FEEDBACK CONTRADICTED ITSELF on a record with no `messageId`. Finding 1
said correlation was "undefined" for it; finding 4 says the reference pairs
id-less records with each other. The second is what the reference does, so the
first was wrong: the problem is not that correlation is undefined but that it
is NOT DISTINGUISHING -- a match that would hold between any two id-less
records in the trace. Only consumers that correlate are affected, which the
text now says.
Also tagged the two trace-notation fences with a language, and the boundaries
heading follows main to ten.
SKIPPED, with a reason.
The stale scenario-count comment in `tck/main.ts` -- "the 5 OCPP 2.0.1
scenarios ... 52 in total" against a registry that now holds 7. Measured, and
the comment is genuinely wrong; it is also pre-existing on main, last touched
by 840f407, and zero lines of this branch go near it. Fixing it here would drag
an unrelated `upstream-patched` re-pin into a pull request about the trace
reader. The finding also asked for the same edit in
`patches/tck/main.ts.patch`, which is generated by `tools/repin-vendored.sh`
and never hand-edited -- that half would have been undone by the next re-pin.

Describe all unreadable refusal causes.
tck/trace.ts returns unreadable for both unmappable records and refused diagnostics. This warning only describes unmappable image records, so it can direct operators to the wrong cause. Use wording that covers validation and mapping failures.
The supplied tck/trace.ts contract shows both refusal paths.

Review findings, verified against the code before being believed.
THE `unreadable` WARNING NAMED ONE CAUSE OF THREE. It told the reader "the
image emits records tck/trace.ts does not map", which was true when mapping was
the only way to reach that refusal. It is not: since the reader moved to
trace-format/, `unreadable` also covers a record off the schema and a
diagnostic this suite refuses over -- an envelope contradicting its own `raw`,
a schemaVersion major this build does not read. Someone reading the old
sentence would look at the producer's frame encoding for a fault that is in the
record around it.
A LEAP-SECOND NOTE THAT SAID THE OPPOSITE OF WHAT HAPPENS. It claimed a
consumer building a `Date` from `23:59:60` "will silently normalise". Measured:
`new Date("2024-12-31T23:59:60Z")` is **Invalid Date**. So the failure mode is
the loud one, not the quiet one, and the note pointed at the wrong risk. It now
states what was measured, asks the document for the behaviour it never
specifies -- reject, preserve or normalise -- and records this library's own:
it accepts second 60 because RFC 3339 does, and constructs no `Date`, so the
string reaches the caller intact. Both halves checked rather than asserted.
`timestamp` WAS NOT THE ONLY MEMBER NOT IN `raw`. `raw` is the OCPP-J array --
message type id, messageId, action, payload -- so `direction` is equally
absent, equally required, and rather more load-bearing: the correlation rule is
written in terms of it, and a producer that mislabels it emits a trace that
validates and correlates wrongly.
And the reused-messageId example described a forward scan, then reported the
failure of a backward one. Both are real failure modes of dropping the clause
and neither is caught by any fixture, so both are now spelled out instead of
being blended into one sentence.
SKIPPED, with a reason.
Adding `permissions: contents: read` to the workflow. The workflow does declare
no permissions, so the finding is factually right, and both jobs already set
`persist-credentials: false`, which is the larger half of that hardening. But
it is pre-existing, applies to the whole workflow including the e2e job this
branch does not touch, and I cannot validate offline that no step needs a scope
it would remove -- `upload-artifact` and `docker compose` run there, and the
job takes 45 minutes to disprove a guess. It deserves its own commit on main,
with the reasoning comment this workflow gives every other setting.

tck/trace.tsread the simulator's JSONL wire trace directly. Reading thatinterchange format is not specific to this suite, and the format already has a
second consumer —
@ocpp-debugkit/toolkitparses the same records — so thereader is now
trace-format/, a library destined for theopen-ocpp-traceorganisation. What stays in
tck/trace.tsis what is genuinely local: which ofthe library's facts are worth refusing a run over, and how a record becomes one
of
ocpp.ts's frames.No issue closed. Context: #65 introduced the trace substrate, #44 removed the
member-order couplings that made a structured reader worth having.
Breaking change
findResponseForno longer scans from index 0 when the CALL is absent from theframes it was handed. A call with no position cannot anchor "most recent
preceding", so it returns
undefinedinstead of correlating against a wire thecall is not on. Every caller in this repository passes a frame from the same
array.
tck/ocpp.tsmovesupstream-verbatim→upstream-patched, with theNOTICEline that obliges.
What changed, by impact
Correlation now follows the format's rule. The specification pairs a
response with the most recent preceding CALL, same
messageId, oppositedirection, not already answered. This suite scanned forward for the first
match — the same rule minus the last clause. The two agree while ids are
unique and diverge on a reused one, where a forward scan hands two calls the
same response.
trace-format/correlate.tsowns the rule;consumerViewandfindResponseForboth call it, so mutating it turns both guards red.A conformant record this runner cannot use now refuses under its own name.
rawandmessageIdare both optional in the schema, so a producer omittingeither is correct — and this runner still cannot judge on the result. Those are
payload-onlyandno-message-id, distinct fromunreadable, because therunner's advice about broken mounts and stale images is wrong for them.
The library takes no error policy and defines no domain model. Its two
consumers are opposites on exactly one axis: a conformance suite refuses a whole
file rather than judge on frames it is unsure of, a debugging UI shows what it
can and annotates the rest. So a diagnostic states a fact and carries no
severity, and a record that satisfies the schema produces no diagnostic
however unusable a given consumer finds it. Zero runtime dependencies.
Verification

tests/spec-invariants.shconfirms no scenario's assertions or call sequence moved.
tests/trace-format.tsandtests/trace-format-standalone.sh, one mutation per claim in each header.Notes for review
tests/trace-format-standalone.shis what keeps the extraction real: oneimportof../tck/would turn the library back into an internal module whileevery other check stayed green.
Two guard rows earned their place the hard way and are worth reading. The
opposite-direction clause first passed a guard that could not distinguish it
from a no-op — every fixture had CALLs travelling one way — so it needed a
shape where the nearer candidate is the wrong-direction one. And two rows of
refusesOverturned out to decide nothing: deleting them left the guard green,so the policy table claimed two judgements it did not make. Both are gone.
trace-format/SPEC-FEEDBACK.mdcollects three findings that need spec textrather than code, to take upstream: the missing vocabulary for "valid but
unusable for my purpose", the consumer split
raw-optional creates with nofixture covering it, and the two correlation clauses the corpus cannot fail
anyone for getting wrong.
trace-format/conformance.tsis offered as a replacement for thespecification's
conformance/validate.mjs, which is currently a secondimplementation of the rules.
