R-PATH's shape dimension joined two records that were both readings of text: the OpenAPI document GitLab generates, for what an endpoint answers with, and a scan of the Grape source, for what gates each field. It now reads the one record a booted GitLab produced, and the two it replaced are deleted.

Every number the change moves, it moves the right way. The endpoint join gains four exact matches and loses three unmatched rows, because Grape's own placeholders are already spelled the way the request inventory records them and the OpenAPI record's were not. The conditions half is the larger gain: a field whose gate could not be read used to be reported as sent unknown, and 1005 of those at package grain and 1000 at type grain are now answered always. The record holds each class as it renders, with inheritance and Enterprise prepends flattened in and every run-time splat already resolved, which is what a scanner could not do.

One silence disappears rather than shrinking. Two records could disagree: a response could name a component the scan had never read, a component could not expose a field the document listed for it, and the conditions half could be missing entirely. All three said unknown. With one record a field is in a response because an entity of that record exposes it, so the same entity always carries its gate, and the three tests that guarded those states are replaced by one that asserts the invariant.

Five declarations go with them. avatar_path and custom_attributes on API::Entities::Member were adjudicated by hand as fields the document lists and no member endpoint sends; the live record simply does not list them, so the judgement a person had to write is one the oracle now makes.

Findings name the entity as Ruby spells it rather than as the OpenAPI document did, because that is the key the record uses and the name to grep the source for.

The deletion is the second commit and goes after the port on purpose: nothing is removed while something still reads it. It takes 3.4 MB of committed JSON, two commands, two readers, two Makefile targets, two CI steps and a 940-line scanner that had to refuse any Grape construct it did not recognise. cmd/internal/provenance drops to two members and its comment says why the shared window survives losing two of the three records that motivated it. The citations that named the deleted files are kept and re-pointed at what was actually read, since the evidence about GitLab is still true and only the local path stopped being.

I verified the whole tree builds, vets and tests, make analyze's step [15/16] now checks the live record, and the statistics, testing reference and package counts are regenerated.

📝 Walkthrough

Walkthrough

The change replaces separate OpenAPI-shape and Ruby-exposure records with one live GitLab API record. Audit checks, Make targets, CI, tests, and documentation now use the consolidated record.

Changes

REST live-record consolidation

Layer / File(s) Summary
Live record model and generator replacement
cmd/internal/apilive/*, cmd/internal/apiexposes/*, cmd/internal/apishapes/*, cmd/gen_api_live/*, cmd/gen_api_exposes/*, cmd/gen_api_shapes/*
Adds live-record route, entity, field, gate, licensing, and persistence helpers. Removes the former shape and exposure packages, generators, and tests.
Audit checks against live data
cmd/audit_1to1/internal/paths/*
Routes, response fields, nested fields, entity names, and field gates now come from apilive. Typed and sent checks share the live condition index.
Build gates and repository documentation
.github/workflows/*, Makefile, CLAUDE.md, README.md, docs/*, internal/tools/*
Removes obsolete generation and validation targets. Updates CI, provenance text, operational documentation, statistics, and source comments for gen_api_live and gitlab-api-live.json.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 48f05

R-PATH can report incorrect field conditions and licensing tiers from the generated live record, and its documentation still points users to a removed record. Resolve these issues before relying on the new workflow.

Comment thread cmd/audit_1to1/internal/paths/typed_shapes_test.go
The four readers of R-PATH's shape dimension joined two records that were both
readings of text: the OpenAPI document GitLab generates, for what an endpoint
answers with, and a scan of the Grape source, for what gates each field. They
now read the one record a booted GitLab produced.

Every number the change moves, it moves the right way. The endpoint join gains
four exact matches and loses three unmatched rows, because Grape's own
placeholders are already spelled the way the request inventory records them and
the OpenAPI record's were not. The conditions half is the larger gain: a field
whose gate could not be read used to be reported as sent "unknown", and 1005 of
those at package grain and 1000 at type grain are now answered "always". The
record holds each class as it renders, with inheritance and Enterprise prepends
flattened in and every run-time splat already resolved, which is what the
scanner could not do.

One silence disappears rather than shrinking. Two records could disagree: a
response could name a component the scan had never read, a component could not
expose a field the document listed for it, and the whole conditions half could
be missing. All three said "unknown". With one record a field is in a response
because an entity of that record exposes it, so the same entity always carries
its gate, and the tests that guarded those three states are replaced by one
that asserts the invariant.

Five declarations go with them. avatar_path and custom_attributes on
API::Entities::Member were declared by hand as fields the document lists and no
member endpoint sends; the live record simply does not list them, so the
adjudication a person had to write is one the oracle now makes.

Findings name the entity as Ruby spells it (API::Entities::Project) rather than
as the OpenAPI document does (APIEntitiesProject): it is the key the record uses
and the name a maintainer greps the source for.

The old records and their generators are untouched here and are still gated.
Removing them is the next change, and it goes after this one on purpose: the
readers move first, so nothing is deleted while something still reads it.
Nothing has read gitlab-api-shapes.json or gitlab-api-exposes.json since the
layer below moved R-PATH onto the record a booted GitLab produces. Both
generators, both readers and both committed records go, with their Makefile
targets, their two CI steps and their sections of the command reference.

That is 3.4 MB of committed JSON, two commands, and a 940-line scanner over
rubocop-formatted Grape that had to refuse any construct it did not recognise.
An instance has already evaluated every one of those constructs.

The two gates become one. `make analyze` step [15/16] and the generated-
artifacts job now check the live record, which asks both questions the deleted
pair asked separately and cannot disagree with itself about the answer.

`cmd/internal/provenance` drops to two members, gen_api_live and
gen_graphql_schema, and its package comment says so: the window it holds was
always a fact about GitLab's release cadence rather than about any one record,
which is why it survives losing two of the three that motivated it.

The citations that named the deleted files are kept and re-pointed at what was
actually read. The evidence in upstream-bugs.md and in four source comments is
about what GitLab's own OpenAPI document said on the day it was read, and it
stays true; naming a file this repository no longer holds is what would have
stopped being true.

`cmd/gen_api_live` gains the reference section it never had, which is now the
only place the REST oracle is described.
The two wait tests below this layer move the coverage the testing reference
records and the counts the README publishes, and a stack refreshes both once,
at its top.
gci reported the file unformatted at one call the reshaped helper introduced.

Worth a line on why it reached CI: the formatter was run through the remote Go
runner, which formats its own copy of the tree and does not send the result
back, so the run reported clean and the committed file was not. Formatters run
locally.
The port gave this package eight exported functions and no tests of its own:
they are exercised through cmd/audit_1to1, so the package read 34.2% and its
new file read zero.

They are worth testing here rather than only through a caller, because each
encodes a decision the caller cannot see. An entity the boot never loaded is
told from one that exposes nothing, since the first says nothing about GitLab
and the second says GitLab sends no fields. A field rendering an entity the
record lacks is left out of the nested map rather than recorded empty, for the
same reason. Two conditions on one field join with && because Grape requires
both. A hash condition speaks through its own data when it has no text, and a
condition with neither contributes nothing rather than a dangling separator.

The marshal in Write becomes cmdutil.Must, the way gen_api_shapes' writer did:
a struct of strings, numbers, slices and maps cannot fail to marshal, and a
branch no test can reach is worse than saying so at the leaf. The two ways
storing can genuinely fail are now told apart and tested, since one is a
directory a caller cannot create and the other a file it cannot open.

The package goes from 34.2% to 100%.
The reader tests below this layer move the coverage the testing reference
records and the counts the README publishes.
The subtest gate caught a loop the reader tests added: a range over the strings
a provenance line must contain, asserting without opening one subtest per case.

Each of those strings is a separate claim about what a reader needs from that
line, so a failure should name which one is missing rather than which loop
failed. That is the whole reason for the rule.
Two routes collapse to one shape when their placeholders differ only in name,
and the shape's response is the union of theirs. The union was carried with a
single entity, the first one a route of that shape named, so a key contributed
by the second route was looked up on the first's entity: answered with that
entity's condition if it happens to expose the same name, and left unknown if
it does not. A wrong answer, not a missing one.

The operation now carries the entity per key beside the union, and both readers
take it from there: the type grain's per-field entity map and the package
grain's first-operation-naming-one rule.

Measured against the pinned record, this changes nothing today: of the 55 shape
keys that hold more than one route, none names two different entities. That is
a property of GitLab 19.3.1 rather than of the design, which is exactly why it
belongs in the structure instead of in a reader's assumption, and why a re-pin
would otherwise have introduced the error silently.
The review fixes below this layer move the coverage the testing reference
records and the counts the README publishes.
Deleting indexOf left its one-line comment attached to the documentation of the
function below it, so stubTypeGrainInputs read as if it built an operation
index.

Break read_source when a one-line block condition balances on its first line.

read_source only breaks after a balanced first line when offset.positive?. conditions_of therefore records the next line in condition.Text. Document.GateOf uses that text as Gate.If or Gate.Unless, and LicensedFeatures scans it for feature names. The committed record contains condition texts with multiple expose calls, so a following exposure can contribute its condition and tier to the current field.
