feat: aggregate every rejection of a parse into one issue trace - #914
Merged

Conversation
Rapiq had two failure channels and both lost information. Drop mode, the
default, discarded disallowed keys, unresolvable paths, bad values and
clamped limits with no way to learn what happened short of diffing the
input against the returned query. Throw mode stopped at the first
violation, so a request with N bad keys took N round trips to fix.
Both now produce a trace of plain-data issues:
const issues: Issue[] = [];
const query = codec.decode(req.query, { schema: 'user', issues });
An Issue carries the machine-readable code, the canonical parameter and
path, the raw client key, the offending value and a severity. It is plain
data, never an Error: a request may produce many, and only the one error a
parse throws pays for a stack.
Under throwOnFailure the parse now records violations, keeps going across
all five parameters, and raises the first error-severity issue at the end
with the whole trace on `error.issues`. The thrown class, code and message
stay those of the first violation, so existing catch logic and assertions
keep working; `issues` is non-enumerable, so neither deep equality nor
JSON.stringify moves. Structural failures (a malformed expression, a
broken $-operator document) still end their own parameter and let the
other four parse, and the raised error keeps the original as its native
`cause`.
Two deliberate behavior changes: validate hooks now run for keys the first
throw used to shield, and a filters `validate` hook returning undefined
raises KEY_VALIDATE_REJECTED under throwOnFailure, symmetric with the
fields/sorts/relations hooks.
`toJsonApiErrors(issues)` in @rapiq/codec-url renders a trace with wire
parameter names, since only the transport knows that canonical `filters`
reaches a client as `filter`.
Closes #896

- Around line 62-80: Keep IssueCollector ownership internal to parser
orchestration: update beginIssues and finishIssues in
packages/core/src/parser/base.ts so nested-parser state, not caller-supplied
options, determines whether failures are thrown, while direct parse calls still
honor throwOnFailure. Remove issueCollector from the public ParseIssueOptions
contract in packages/core/src/parser/types.ts, and stop re-exporting
IssueCollector from packages/core/src/parser/index.ts.
In `@packages/core/src/parser/issue.ts`:
- Around line 127-143: Update the issue-retention logic around failure
assignment and the MAX_ISSUES guard so the first error issue is retained even
when the trace is already full: replace a retained warning when necessary, and
mirror that bounded replacement in this.sink. Preserve the first-error failure
behavior and the existing cap for subsequent issues.
In `@packages/core/src/parser/parameter/filters/validate.ts`:
- Around line 53-74: Update rejectLeaf and the filter-validation APIs to accept
the effective throwOnFailure policy, using the parse-level override when
provided and the schema value otherwise. Pass this policy from both synchronous
and asynchronous callers, including recursive validation calls, so rejected
leaves throw when parsing with throwOnFailure enabled. Add regression coverage
for the Simple and Mongo parsers.
In `@packages/docs/guide/errors.md`:
- Around line 161-170: Update the parser.parse example in the documentation to
include throwOnFailure: true in its parse options alongside the user schema,
ensuring invalid input raises the first error and reaches the catch block.
In `@packages/parser-expression/src/parameter/filters/module.ts`:
- Line 275: Thread the active collector returned by beginIssues through the
filter parser call chain: update parse and parseAsync, then build and
buildAsync, to pass it into parseValidated and parseValidatedAsync, and use that
collector in applyFiltersSchemaValidation instead of options.issueCollector.
Update corresponding parseExact and parseExactAsync forwarding, preserving
undefined where those methods intentionally have no active collector.

… modules
Three defects found auditing the trace layer, each pinned by a regression
test:
- Under throwOnFailure, a preserve()d condition over a relation the relations
hook rejected raised SCHEMA_PRESERVED_CONDITION_PRUNED instead of the
relation rejection itself: pruning now runs where the old code had already
thrown, and the conflict it finds is a CONSEQUENCE of the rejection. Relation
pruning and the index policies are skipped once the trace has failed, so the
raised error stays the first violation.
- The MAX_ISSUES cap could evict the very issue the raised error was built
from, handing a consumer rendering error.issues a 400 with nothing in it.
The failure is exempt from the cap.
- A standalone expression parse raised an error with an empty `issues`, though
rendering a failure goes through that property. The dialect is fail-fast by
design, so its structural failure is recorded and re-raised rebuilt, with the
original as `cause`.
Also splits the issue modules into directories per the repo conventions:
errors/issue/{constants,types}.ts and parser/issue/{constants,module}.ts,
instead of two files mixing types with constants and implementation.
An audit of the trace layer (six adversarial review passes, each finding verified by refutation) found the ownership rule was reachable from outside: `issueCollector` sat on the public `ParseIssueOptions`, and `finishIssues` decided whether to raise by comparing against it. A consumer supplying one therefore switched OFF the failure policy — the parse recorded the rejection, raised nothing, and, because the post-passes skip an already-failed trace, returned a query still carrying the relations the validate hook had rejected. The trace is now an explicit driver argument on `parseParameter`, exactly like the relation ledger and for the same stated reason: a driver a consumer can supply is a decision a consumer can take away. Every other entry point owns its trace and raises it. Two more confirmed defects, both pinned by tests: - The filters `validate` rejection read `schema.throwOnFailure` alone, so it was the one violation a call-time `throwOnFailure` override could not govern. It now uses the same `throwOnFailure ?? schema.throwOnFailure` formula as every other site. Deliberately NOT the resolving scope's policy: the expression dialect forces its scope to throw because an expression cannot be partially reinterpreted, which says nothing about whether a policy hook declining a leaf should fail the request. - The expression parser handed the ENCLOSING parse's collector to the leaf validator, so a standalone parse recorded none of its validator drops.
The page still said a rejected leaf is dropped 'independent of the throwOnFailure policy', which stopped being true when the hook joined the symmetric failure model.
A structural failure ends its parameter by throwing rather than by dropping a key, so it escaped the standalone entry points before anything recorded it: a caller catching it got an error whose `issues` was empty, and `toJsonApiErrors(error.issues)` — the documented way to render a failure — answered with an empty `errors` array. Only the expression dialect was wrapped, and only for its own grammar aborts. `BaseParser.recordFailure`/`recordFailureAsync` now wrap every standalone entry point across the three dialects: the throw is recorded and re-raised through the trace, so the error that leaves carries it (and the original as its `cause`). An abort that follows an earlier rejection does not displace it — the raised error stays the first violation, with the abort recorded behind it. A call driven by an enclosing query parse records nothing and simply propagates, leaving the per-parameter fold to the orchestrator. The expression parser drops its local copy of the helper in favour of the shared one.

The `issues?: Issue[]` sink was an output parameter smuggled into an options
bag that otherwise says only HOW to parse, and nothing else in the library
reports that way. It is gone: the trace now reaches a caller exactly one way,
on the error a parse raises, which is where the aggregate already lived.
try {
codec.decode(req.query, { schema: 'user' });
} catch (e) {
e.issues; // every violation, not just the one that raised
}
That drops observability for the default drop policy, which is deliberate:
`throwOnFailure` is what turns rejections into something to inspect, and a
parse that raises nothing discards its trace. Warnings (a clamped limit,
substituted defaults, entries a rejected relation dragged along) still ride
along behind the failure, so an error explains what else the parse did while
failing.
`ParseIssueOptions` disappears with the sink, and codec-url no longer needs to
strip the trace out of the options it forwards to the internal validation
decode of a schema-aware encode.
…singular `failureErrors` held one class, not a collection. The plural came from echoing the existing `errors: typeof ParseError` option, which is itself a singular-valued name that should not have spread to new members. It is `failureClass` now, and the two parameters feeding it are `errorClass`. The collector also referenced the concrete `ParseError` where all it needs is a contract, so `IBaseError` / `IParseError` / `IParseErrorConstructor` now describe what an error IS and what rebuilding one from its issue REQUIRES. `BaseError` and `ParseError` declare the contracts they satisfy, and the collector depends on nothing else — a dialect package can name its own error class as the rebuild target, which a test pins. PARAMETER_ERROR_CLASSES stays typed by the class: the resolver reaches for the static factories through the same table, while a rebuild only ever needs the constructor.
The name said JSON:API, but the function is this codec's normalization: it
decides the response members and maps the canonical parameter a parse reports
onto the wire name a client actually sent. That the members line up with the
JSON:API error object is what the query vocabulary is modelled on, not what
the function is.
`toJsonApiErrors` is `formatErrors`, `JsonApiError` is `FormattedError` and
`JsonApiErrorsOptions` is `FormatErrorsOptions`. The flat json-api.ts becomes
error/{constants,module,types}.ts, so the wire-name table, the shape and the
implementation stop sharing one file.
A variable holding a collector was called `issues`, which is the name of the `Issue[]` that collector exposes. Every threaded field, parameter and local is `issueCollector` now, and only the accessor returning the array keeps the plural. The type is `IIssueCollector` rather than the class: a parser that wants to observe or wrap the recording can supply its own, and nothing downstream depends on the implementation. `IssueCollector` declares it, so the contract is checked rather than assumed. The `IssueTrace` alias is gone with it. Note for next time: `npx nx run @rapiq/<pkg>:build` swallows the tsc failure and still reports a duration, so a rename that breaks build:types reads as a successful build. Run tsc from the package directory, or pass --verbose.
`IssueCollector` was doing two jobs: gathering evidence and deciding what to throw from it. It now only collects and serves — `record`/`violation`/`notice`, the `issues` it holds and the `failure` among them — while `buildIssueError` and `raiseIssueError` turn that failure into an error. The failure is one value now (`IssueFailure`: the issue, the class the failing site named, the throw it was caught as) instead of three parallel fields, which is what made the split obvious: everything the rebuild reads travels together, and nothing about HOW to rebuild lives on the collector. A caller that wants the trace without the raise builds no error at all, and a parser supplying its own IIssueCollector no longer has to reimplement error construction to satisfy the contract.
…ector "Issue error" named a kind of error that does not exist. The functions build a ParseError FROM what a collector holds, and the names say so now.
`instanceof ParseError` compares class identity, which two copies of @rapiq/core in one process do not share — mixed ESM/bundled builds, a dual-packaged dependency. The failure mode was quiet and bad: the per-parameter fold would rethrow a foreign ParseError instead of recording it, and the trace would come back empty, so an endpoint rendering error.issues would answer a 400 with nothing in it. `isBaseError` / `isParseError` read a `Symbol.for` brand every rapiq error carries, mirroring CONDITION_MARKER, which the condition nodes have used for the same reason all along. The brand is non-enumerable like `issues`, so it changes neither deep equality nor JSON.stringify. Every internal error-path check uses the guards now, and the docs teach them instead of instanceof. Answers "why not ebec": its markInstanceof was the one thing that evaluation left on the table, and it costs a symbol and eight lines to have here.

changed the title
A second audit of the redesign found this merge-blocking, reproduced by execution: `IssueCollector.error()` nominated the caught throw's own `constructor` as the rebuild target, unchecked, and `isParseError` admits any object carrying the brand. For an error class whose constructor is not `BaseErrorOptions`-shaped, the rebuild destroyed it: - an app-defined `TenantParseError(field)` came out with `message: 'The field [object Object] ...'` and an empty `issues` - a hand-branded stand-in — the exact value the guard test blesses — came out a plain Error with `code: undefined`, no `issues` and the brand stripped, so the documented handler rethrows and answers 500 instead of 400 - a class with a bespoke options shape threw a raw TypeError out of the parse A regression, too: on master such a throw propagates intact. An error the parse CAUGHT is now re-raised as itself with the trace attached through `attachIssues`, which `BaseError` already made possible by declaring `issues` configurable. Class, code, message, stack and brand all survive because nothing is reconstructed; only a violation that was recorded rather than thrown is still built from its parameter's class. `cause` goes away on that path, since an error cannot be its own cause. Also corrects two claims the redesign left wrong in guide/errors.md: a limit above maxLimit is a rejection under throwOnFailure rather than an unconditional warning, and an abort is raised as itself rather than wrapped.

…e down
Four hand-rolled versions of helpers this repo already ships, all of them
subtly weaker than the real thing:
- `isMarked` re-implemented an object check that `isObject` does (and it also
excludes arrays)
- three sites split a dotted key with `split('.')`, which tears a segment
carrying an escaped dot in half; `toIssuePath` wraps pathtrace's
`pathToArray`, the same dependency core already parses paths with
- `formatErrors` rejoined a path with `join('.')` instead of `arrayToPath`,
which re-escapes the segments that need it
This keeps happening, so .agents/conventions.md now carries the rule as a
table of reach-for/instead-of pairs, and the note that
`nx run <pkg>:build` reports success while build:types fails.
PARAMETER_ERROR_CLASSES and PARAMETER_WIRE_NAMES are internal lookups nothing outside their own package reads, and both are mutable Records. They reached consumers only because their modules were re-exported wholesale.

Marking this a draft: the That is not cosmetic. The flat model gives Settled with it: The branch is green and audited at 187ab76 if a revert point is wanted; the spec is in the local plan doc. |
…ties Adopt the issue model validup defines and authup consumes: an `IssueItem` leaf, an `IssueGroup` that nests, and a `path` every node carries in absolute form because whoever merges a nested trace rewrites its children. `severity` goes away with it. Under a dropping policy a site now records nothing at all: the key is dropped, nothing will be raised, and a trace nobody can read is a trace nobody should pay for. Every issue is a failure, so the raise rule is "the first issue", full stop, and the notices (defaults applied, what a rejected relation dragged along) stop being recorded. The point of the inversion is that a path-less issue can no longer be constructed. A fail-fast site attaches the position it found the violation at to the error it throws, and the catching driver merges that trace instead of synthesizing `path: []` from the parameter name -- which is what every expression-dialect key rejection used to come back as. `formatErrors` renders the leaves of the tree and loses its `warnings` option.
Document the two node kinds, the absolute-path-through-merging rule and the leaf helpers; drop severity, the warnings option, and the notices that no longer exist.
`parseParameter` is the query orchestrator's entry into a sub-parser, but nothing stops a caller from using it directly, and then it owns the trace: a structural abort has to be recorded on the way out or the error leaves with an empty `issues` and `formatErrors` answers with nothing at all. The expression filters parser had no lifecycle there at all; the other four had one that a throw walked straight past. Both routes now go through `recordFailure`, so first-issue-wins holds for an abort driven directly too.
…orders `IParseErrorConstructor` described the constructor a rebuild needed; nothing rebuilds. `ErrorMessage.defaultsApplied` was the notices' message; there are no notices. `IssueMeta` had one consumer, and it was the type declared under it. None of the three shipped, so none of them are a removal anyone can feel. `IssueCollector.violation` / `error` say what they are, not what they do, and both do the same thing: add to the trace. They are `add` and `addError` now, and `record` — which only they and `merge` call — is protected rather than part of the contract.
`add` took the failure policy and binned the issue when it was a dropping one, which meant every drop built an issue in order to throw it away, and made the trace a participant in a decision it does not own. The decision now sits where it is made. Two of the five sites were already inside `if (throwOnFailure)`, so they were passing a constant; the other three gained the guard before they build anything. The collector-level drop test goes with it: what it asserted is a property of the recording sites now, and the parser suites already assert it end to end.
Write down that the error-group mechanism is not rapiq's model, and why the empty-contract half is the worse one: the tempting fix for an unfilled `errors` is to fill it, which is an Error per rejected key.
rapiq had grown its own `Symbol.for` brand machinery, which is the house
facility `@ebec/core` already provides and a weaker version of it: one boolean
per level, so every class marks itself twice and every subclass needs its own
marker and its own guard. ebec keeps an ancestor CHAIN under one
non-enumerable key, which a subclass inherits by construction.
The chain also serializes, which closes a gap rapiq had rather than tidying
one. `JSON.stringify(error)` emitted `{"code":"…"}` — no message, no trace —
so an error that crossed a worker, an SSR hop or a gateway arrived saying
nothing. `toJSON` now carries name, message, code, issues and the chain, and
`isParseError` matches the plain object on the far side.
The wire shape is rapiq's, not ebec's: `issues` is the aggregate, and
`errors: Error[]` is deliberately not adopted. Everything rapiq aggregates is
a client-input rejection, which is data; declaring a group contract it would
never fill would make ebec-aware tooling report a twelve-rejection failure as
childless.
Written spec-first, and it earned its keep immediately: rapiq errors have
always reported `name: 'Error'`, because nothing set it and nothing looked.
Taking only the brand helpers left rapiq re-implementing the rest of what an error base does: the class name (which I had just hand-written), the stack capture (which rapiq never did), the `code` assignment, the `cause` passthrough. Extending removes all four, and `toJSON` becomes the base's plus the one key that is rapiq's. The objection I had raised against this does not survive measurement. ebec's `errors` is an optional field rapiq leaves unset, so `isBaseErrorGroup` correctly answers false; an unset optional is not a lie. What it does change is the enumerable shape, which gains ebec's unset `cause` and `errors` — cosmetic, because neither varies with the input, and the trace stays non-enumerable where deep equality can't see it. The brand chain now leads with ebec's own marker, so ebec's guard recognizes a rapiq error through the chain rather than by duck-typing it. Two shape assertions moved from naming the exact key list to naming the property they were protecting, with the list pinned in one place: a field added upstream should fail the wire-shape spec, not three unrelated ones.
…he scope `ResolutionScope` carried a `typeof ParseError` through every descent and every `withSegment`, to arrive at a value it could read off its own `parameter`. Nothing ever passed a non-default one, so the context member was carriage for an extension point no caller used. The class is looked up where it is thrown now, and `ResolutionScopeContext.errors` goes with it. The static factories take the issues instead, so a fail-fast throw carries the position it was found at through the front door rather than having it bolted on afterwards. `raising()` disappears with `attachIssues`, whose other reason — attaching a trace to an already-caught error — died with the re-raise path. `issues` stays out of the enumerable shape, now via a `defineProperty` in the constructor rather than a helper: vitest's deep equality reads enumerable own properties, so as a plain field it would make two failures of the same kind compare unequal as soon as they carried different traces.
`issues` was installed non-enumerably so that two failures of the same kind
would compare equal however many keys the client got wrong. The trade goes the
other way now, deliberately: the trace is visible when an error is inspected or
spread, which is where you look for it first, and the cost is that deep
equality compares it.
That cost is real and it landed immediately: nine expression specs asserted
`toThrow(FiltersParseError.keyNotPermitted('age'))`, which now demands the
expectation carry the same issues. They assert what they meant instead — class,
code and message — through an `expectThrown` helper, which is also the advice
the guide now gives consumers.
`code` was rapiq's closed union, which is not a world rapiq controls: a trace
can merge issues another library recorded, and a consumer's error class
carries its own code. Widening it to `string` said that honestly but gave up
the compiler on the one thing the docs tell consumers to do — branch on
`code`, where a typo then compiles.
`ErrorCodeInput` is `` `${ErrorCode}` | (string & {}) ``: autocomplete and
typo protection for rapiq's codes, foreign ones still assignable. It is the
idiom blemish uses for `IssueItem.code`, so the trace and the error that
carries it now agree, and it satisfies ebec's `code: string` so `IBaseError`
still extends it.
`withTrace(driver, parameter, fn)` made half its call sites pass a literal
`undefined` to say "nobody handed me a trace" — an argument carrying no
information, in the position a reader looks at first. An overload could not
split the cases either, since `parseParameter` passes a driver that is itself
optional.
`withTrace({ parameter }, fn)` at an entry point and
`withTrace({ parameter, driver }, fn)` when a query parse drives it, which is
how every other multi-argument seam in the parser is passed.

- `SimplePaginationParser.parseParameterAsync` wrapped its result in a promise but ran the body outside one, so a raise escaped synchronously and a caller's `.catch()` never saw it. Marked `async`, with a regression test; the other dialects already declared it that way. - The doc example for rendering a decode failure swallowed everything that was not a parse error: no response, no rethrow. It rethrows now, as the errors guide already did. - `filters.md` claimed a rejected leaf is reported "either way". Under a dropping policy nothing is recorded at all; the raised error is the only channel. - The `ParseTrace` doc block was orphaned when `ParseTraceContext` was inserted above it, so two blocks preceded one declaration and the `owned` rationale attached to neither. - `architecture.md` still called the issue model validup's; it is blemish's. - `expectThrown` accepted a subclass where it means the class itself, and the expression default-substitution test asserted a count where it means a predicate. Recorded the public API changes in the migration ledger: the removed `ResolutionScopeContext.errors`, the general raise, the enumerable trace and the new `toJSON`.
* docs: specify issue trace hardening * chore: ignore worktree directory * fix(core): bound issue traces by leaf count * fix(core): synchronize mutable issue traces * fix(core): redact issue input during serialization * fix(core): harden issue property serialization * fix(parser): retain standalone structural failures * fix(parser): report absolute filter issue paths * test(parser): cover nested filter issue context * fix(parser-simple): locate nested input failures * fix(core): isolate indexed parameter failures * fix(parser): validate input under empty allow lists * docs: clarify issue trace boundaries * docs: clarify exact issue traces * fix(core): retain terminal issue traces * fix(core): retain contextual issue traces * refactor(core): simplify issue serialization Strip expected and received while recursively copying the issue tree.

Relation pruning now always yields the tree that would execute, so the filters/sorts index policies no longer report the keys a rejected relation dragged along as index violations of their own, and a preserved condition over a rejected relation can no longer surface as a SchemaError displacing the recorded client rejection: only pruning's refusal is suppressed once the trace has failed. The query orchestrator runs its cross-parameter passes inside the trace, so a rejection thrown there cannot leave with an empty trace. Two more parser findings from the same review: - the simple filters parser recorded KEY_VALUE_INVALID at a path relative to the nested relation scope; it is absolute now, message included - an all-denied fields schema (allowed: [] and default: []) again contributes nothing below it, relation defaults included, but the client keys are still resolved so a throwing policy reports them
Left to the base substrate, new BaseError('message') got the class name
as its code (BASE_ERROR, PARSE_ERROR, ...), a value outside rapiq's
vocabulary and different from the option form's default.
formatErrors imports arrayToPath from pathtrace, which the package did not declare, so the bundle carried a private copy next to the one core externalizes.
The per-parameter pages, the parser package pages and the drop-vs-throw sample still promised the pre-aggregation contract (a parameter's own class and code on the thrown error); they now point at the inputRejected failure and its issue trace, and errors.md records that a ParseError a validate hook throws becomes an issue on the aggregate and that the index policies judge the relation-pruned tree. Comments and docs added on this branch used em dashes against the repo convention; replaced. Also fixes the orphaned RelationLedger doc comment, a dangling ErrorMessage comment, three stale "first issue" comments and a misnamed test.

- Around line 108-113: Update raise in the parser base so it reuses or rebuilds
the first error-severity issue from trace.collector. Preserve that issue’s error
class, code, and message, attach the complete trace to it, and retain
parameter-specific error-class handling without replacing query-level errors
with ParseError.inputRejected.
In `@packages/core/src/parser/parameter/filters/validate.ts`:
- Around line 74-91: Update the rejectLeaf documentation to state that no issue
is recorded when the effective throwOnFailure policy is false, while retaining
the KEY_VALIDATE_REJECTED behavior only for throwing validation. Keep the
rejectLeaf implementation unchanged.
In `@packages/core/src/parser/parameter/validate.ts`:
- Around line 404-415: Update the key-validation rejection flow in validate.ts
to construct a single IssueInput and pass buildIssue(issue) to
keyValidateRejected when no issueCollector exists, while preserving the
collector path. Extend ParseError.keyValidateRejected to accept the optional
issues argument and propagate it into the standalone error.
In `@packages/docs/guide/errors.md`:
- Line 200: Correct the documentation describing the issues property so it
states that issues is non-enumerable and therefore does not appear in object
spreads or normal deep-equality key traversal; retain the guidance about
asserting the error class, code, or issues directly.
Apply the same fix in `@packages/core/src/errors/base.ts` around lines 44 - 65.
In `@packages/docs/guide/recipes/express-typeorm.md`:
- Around line 81-82: Update the isParseError response to format e.issues with
formatErrors using status '400', and return the formatted result in an errors
array so clients receive parameter/path-level parse details. Preserve the 400
status and update the corresponding guide documentation for this user-facing
response change.
In `@packages/docs/guide/schemas.md`:
- Around line 420-426: Update the second parser example’s catch block to narrow
the caught value with isParseError before accessing issues, matching the guarded
pattern established in the first example.
In `@packages/docs/packages/parser-expression.md`:
- Line 65: Update the parser policy documentation to distinguish unconditional
failures from policy-driven rejections: malformed syntax and invalid or
disallowed expression keys must always fail, while validator and relation-policy
rejections from filters.validate follow the effective throwOnFailure setting and
may drop when it is absent.
In `@packages/parser-mongo/test/data/expect.ts`:
- Line 9: Add blemish to the devDependencies of the package manifests for
parser-mongo and parser-expression, covering the imports in test/data/expect.ts
so isolated installs resolve the test dependency without workspace hoisting.
In `@packages/parser-simple/src/parameter/fields/module.ts`:
- Around line 319-326: Update the allDenied handling in the fields parsing flow
to traverse client-supplied nested relation groups using the same validation and
issue-collection logic as the loop later in the method. Return the empty Fields
projection only after nested validation completes, preserving rejection behavior
in throw mode for denied fields such as items.secret.

Repo convention: test-only imports resolve through workspace hoisting and are not declared per package (parser-simple, parser-expression and parser-mongo tests all import blemish the same way, and blemish is a dependency of @rapiq/core, which every test already resolves). Not changing.
…ed projection The all-denied short-circuit returned before descending into the relation groups, so a nested client key under an all-denied root was never resolved and a throwing policy recorded nothing for it. The projection is discarded after the traversal now.
…ECTED throw A key or leaf validator rejection thrown outside a collecting parse now attaches its issue to the error, like every other fail-fast site, so a catching driver merges the position instead of synthesizing a path-less one. Also corrects the rejectLeaf doc block: nothing is recorded on the drop path.
…e the expression policy split The codec recipes answer with formatErrors(e.issues), the mongo recipe with the flattened leaves; the schemas.md sample narrows with isParseError before reading issues; parser-expression.md separates the always-failing grammar and key violations from the policy-driven validator and relation rejections.

Problem
Both failure channels lost information. Throw mode stopped at the first violation, so a request with N bad keys took N round trips to fix, and the error carried only
codeplus an English message: no parameter, no path, no offending value in machine-readable form. Drop mode discarded disallowed keys, unresolvable paths, unusable values and clamped limits with no way to learn what happened short of diffing the input against the returned query.What this delivers
A parse records what it rejects and raises one failure at the end, carrying the whole trace:
INPUT_REJECTED. A single-parameter parse (parseFields,SimpleSortsParser.parse, ...) raises its parameter's class; a whole-query parse raises the generalParseError, because a request can violate policies in four parameters at once and an error advertising one of them would describe a subset. Sub-parser failures inside a query parse are merged into its trace, never raised.IssueItem | IssueGroup, nesting is the tree), plain data rather thanErrors: a request may produce many, and only the one error a parse throws pays for a stack. rapiq keeps its singleErrorCodevocabulary and claims twometakeys,parameterandkey, read throughextractIssueParameter/extractIssueKey; the offending value is blemish'sreceived. Every node'spathis absolute (a parent rewrites children when merging), soflattenIssueItems(e.issues)hands out leaves that already know where they sit.throwOnFailureis what makes rejections inspectable.$-operator document, an input of the wrong shape) and the other four parse on; the abort becomes an issue like any other rejection. A site that cannot record (the expression dialect resolves keys under an always-throwing scope, since an expression cannot be partially reinterpreted; aResolutionScopeused outside a parse) attaches its issue to the error it throws and the catching driver merges that trace.MAX_ISSUES(100) counts leaves, group shape is preserved, a late structural abort displaces only the newest ordinary leaf, and the first retained violation is never displaced.formatErrorsin@rapiq/codec-urlrenders the leaves of a trace into a response body, mapping the canonical parameter onto the wire name the client sent (filterstofilter); the members follow the JSON:API error object.BaseErrorextends@ebec/core's and is branded through its@instanceofchain:isBaseError/isParseErrorreplaceinstanceofon any boundary a second copy of the library, or a serialized error, could reach;toJSONemits the chain and the trace (withreceivedredacted). rapiq deliberately does not adopt ebec's error-group half: what it aggregates is client-input data, carried asIssue[].Deviation from the issue

parse()/parseAsync()signatures and return types unchanged; the trace is a driver argument onparseParameter, never a parse option.inputRejected, and only a single-parameter parse names its parameter's class. Branch onisParseError(e)ande.issues, not oninstanceof.BaseError.issuesis an ordinary enumerable property, so deep equality compares traces:toThrow(<error instance>)asserts the trace too. Assert the class, the code, or the trace.validatehooks now run for keys the first throw used to shield; a filtersvalidatehook returningundefinedraisesKEY_VALIDATE_REJECTEDunderthrowOnFailure, symmetric with the other hooks; aParseErrora hook throws is caught like a structural abort and becomes an issue on the aggregate.new BaseError('message')and the option form both defaultcodetoErrorCode.NONE.Design notes (settled, recorded in
.agents/architecture.md)add/addError/merge,issues,failed); the call that owns the trace raises it (BaseParser.withTrace,ParseTrace = { collector, owned, parameter? }). Contracts, not classes:IBaseError,IParseError,IIssueCollector.throwOnFailure ?? schema.throwOnFailure, deliberately not the resolving scope's: the expression dialect forces its scope to throw for key resolution (resolutionThrowOnFailure), which says nothing about a policy hook declining a leaf.SCHEMA_PRESERVED_CONDITION_PRUNEDrefusal is suppressed once the trace has failed, so a structural conflict found while cleaning up cannot displace the rejection. A parameter's index policy is skipped only after that same parameter's prior failure.ErrorMessagebuilders theParseErrorstatics delegate to, so recording costs no stack capture and the two channels cannot drift.Audits
