Conversation
…the rich layer graphify/extractors/k8s_manifest.py: recognizes real Kubernetes resources (apiVersion+kind+metadata, value-validated) and extracts owner-reference edges (both standard metadata.ownerReferences and this repo's own osac.openshift.io/owner-reference annotation convention, plus osac.openshift.io/tenant scoping -- confirmed against osac/.claude/rules/architecture-patterns.md and the operator's own Go source), ConfigMap/Secret references, *Ref/*Refs CRD cross-references (confirmed against real usage in osac-operator's CRD samples), and label-selector matches via a shared label-hub node (confirmed exact against a real Service/Deployment pair in osac-operator/config/console-proxy/). Direction change confirmed explicitly mid-implementation: rather than stay k8s-only, ANY YAML or JSON with no recognized schema now also gets a generic structural walk (graphify/extractors/yaml_generic.py, graphify/extractors/json_generic.py) instead of staying invisible -- layered under the k8s-specific extractor via graphify/extractors/yaml_dispatch.py, matching how extract_json already layers config-JSON extraction over a (previously empty, now generic) fallback for data JSON. detect.py now routes ALL .yaml/.yml to FileType.CODE unconditionally, matching .json's existing precedent. Go-templated Helm chart YAML (confirmed empirically to break the tree-sitter-yaml grammar outright, producing a root ERROR node rather than a partial tree) is detected per-document and skipped with a one-line warning, never crashed on or walked for garbage structure. Real, measured corpus impact against the actual osac repo (before/after on the same commit): 96,879 -> 396,492 nodes, query wall-clock 26.2s -- both well past the established ceiling (170K nodes / 10s). Root-caused: 70% of the new nodes come from one vendored third-party tree (osac-aap/vendor/ansible_collections) that contributed nothing under the old YAML-is-a-document behavior. Estimated ~118K nodes with that tree excluded, comfortably under ceiling -- the fix is a .graphifyignore change in the osac repo, not a defect in this extractor; shipping this PR now on that basis, per explicit decision. Full test suite: 4390 passed, 0 failures (one pre-existing, unrelated flaky test confirmed passing in isolation).

Two real bugs found in review, both verified empirically before and
after the fix:
1. Namespace-scoping bug in ownerReference resolution, reproduced
against this PR's own manager.yaml-style example (Namespace owning a
Deployment). The owner lookup was keyed by the CHILD's own namespace,
but a cluster-scoped owner (Namespace, ClusterRole, a CRD, ...) is
indexed with no namespace at all -- guaranteed miss, minting a
duplicate stub instead of linking to the real node. Fixed with
_resolve_owner(), which tries cluster scope for well-known
cluster-scoped kinds and falls back to trying both the child's
namespace and cluster scope otherwise.
This was compounded by a second, real bug in yaml_dispatch.py: it
called extract_k8s_resources() once PER DOCUMENT instead of once per
file, defeating the two-pass same-file design k8s_manifest.py's own
comments already claimed -- each document got its own empty
local_nids scope, so a same-file forward reference (the Namespace
declared before the Deployment that owns it) was never visible when
resolving the owner. Fixed by classifying all documents first, then
extracting every k8s-shaped document in the file together in one call.
2. The templated-Helm-chart safety net was unreliable in both
directions, not "always warns and skips" as originally claimed.
Verified empirically: a bare inline template value like
"replicas: {{ .Values.x }}" (the single most common Helm templating
idiom) parses with has_error=False on the specific document node
checked -- the template markers look like valid, if bogus, nested
flow-mapping syntax to the grammar, not a parse error, so it was
silently extracted as a clean resource. Concatenated template blocks
like "image: {{ .Values.x }}:{{ .Values.y }}" go the other way:
has_error=True on the parse tree's stream root but NOT on the specific
document node checked, so it silently produced zero output with no
warning. Fixed by also checking the document's raw text for a literal
template-open marker, independent of has_error -- confirmed this
catches both directions.
New tests assert on real node-ID uniqueness (a set of ids, and the built
graph via build_from_json) for the cluster-scoped-owner scenario, not
label-based _rel_pairs/_labels helpers, which are blind to two distinct
node dicts sharing the same label -- exactly the shape the first bug
produced. Plus direct regression tests for both new templated-YAML repro
patterns.
Full suite: 4395 passed, 0 failures.

lines 89-100 and graphify/extractors/yaml_generic.py lines 92-98 to track
visited mapping keys and array items independently of deduplicated nodes,
stopping when the visited-position count reaches MAX_NODES_PER_DOCUMENT;
preserve the existing node and contains-edge behavior for positions processed

- Around line 372-400: Update the manifest parsing flow to retain each
resource’s API group derived from apiVersion, include it in _resource_id and the
local_nids key so same-named resources from different groups remain distinct,
and use ownerReferences[].apiVersion when resolving owners. Add a regression
test covering two API groups defining the same kind, namespace, and name.
- Around line 484-486: Update extract_k8s_manifest() to apply the same
invalid-template gate as yaml_dispatch.py before collecting resource_tops:
reject documents when root.has_error is true or the raw input contains the {{
marker, returning empty nodes and edges. Preserve normal extraction for valid
non-templated Kubernetes manifests.
In `@graphify/extractors/yaml_generic.py`:
- Around line 118-120: Update the scalar-root handling in _walk and extract_yaml
so scalar YAML documents create a document-root node connected to file_nid
instead of returning no nodes; preserve existing mappings and sequences, and add
a regression test covering a scalar document such as enabled.
In `@tests/test_k8s_manifest.py`:
- Around line 37-39: Limit the _require_grammar autouse fixture to tests that
exercise YAML extraction so classify_file() coverage remains runnable without
tree_sitter_yaml. Move the classify_file() tests to a fixture-free module or
apply the skip selectively to extractor tests, preserving the existing grammar
requirement where parsing is actually used.

…, template-gate bypass, scalar roots, test scoping All verified against actual current code before fixing; all 5 were real: 1. yaml_generic.py / json_generic.py: MAX_NODES_PER_DOCUMENT was checked against len(nodes), which is deduplicated via seen_ids. Confirmed real: make_id(path, "a.b", "c") normalizes to the same id as make_id(path, "a", "b.c") -- a mapping key containing "." collapses two genuinely different structural positions. This let the walk visit unboundedly more positions than the cap intends while len(nodes) stayed under it, defeating the safety valve for exactly the pathological, deeply-nested files it exists to bound. Fixed with a separate `visited` counter incremented per position considered, independent of dedup. 2. k8s_manifest.py: resource identity was (kind, namespace, name) with no API group, so two different API groups defining the same kind/namespace/name (a legitimate real k8s scenario -- apiVersion exists precisely to allow this, e.g. NetworkPolicy historically existed in both extensions/v1beta1 and networking.k8s.io/v1) would silently collide into one node -- the same class of bug as the namespace-scoping fix from the previous round. Fixed: _api_group() extracts the group from apiVersion (deliberately excluding version, since the same group+kind+namespace+ name accessed via a different version is the same logical resource, not a distinct one), threaded through _resource_id, local_nids keys, and ownerReferences resolution (which always carries its own apiVersion). ConfigMap/Secret refs use the core group (always correct, no ambiguity). *Ref/*Refs convention references (which carry no apiVersion of their own) default to the referencing resource's own group -- a documented, reasonable approximation, not a perfect resolution. 3. extract_k8s_manifest() -- confirmed via grep it is NOT wired into _DISPATCH (unreachable from the real extraction pipeline) but IS a real, re-exported, directly-callable entry point (used throughout this test file, importable via graphify.extract) that lacked the has_error/template-marker gate yaml_dispatch.py has. A templated file routed through this function directly would have been silently mis-extracted. Fixed by moving the shared gate into _yaml_cst.is_unparseable() and filtering in all_top_level_mappings() itself (which both extract_k8s_manifest and yaml_dispatch already route through), rather than duplicating the check in a second place. 4. yaml_generic.py / json_generic.py: a document that's a bare scalar at the top level (e.g. a file containing just `true` or `"hello"`, no mapping or sequence at all) produced zero nodes -- not even a file node, since the caller only creates one when the walk returns at least one node. Directly contradicts the "nothing invisible" goal universal coverage exists for. Fixed: mint a doc-root node for the scalar, connected to file_nid. 5. tests/test_k8s_manifest.py: the module's autouse _require_grammar fixture (skips if tree_sitter_yaml isn't installed) applied to two classify_file()-only tests that never parse YAML content and don't need the grammar at all -- reducing real coverage when the optional [yaml] extra is absent. Moved to a new, fixture-free tests/test_k8s_manifest_classify.py; confirmed passing with the extra uninstalled. 9 new/moved regression tests. Full suite: 4398 passed, 0 failures. ruff check: clean.

Closing without merging — deliberate decision, not abandoned mid-review. This PR's motivating use case (making CI/merge-queue "is everything healthy" questions cheaper/better via the brain) was tested with two separate real trials after the extractor work landed:
Root cause, not a fixable bug: this class of question needs live GitHub state (branch protection, actual required checks, run history, live queue state) that no structural code graph — however complete — can ever hold. A follow-up attempt to find a different supporting use case (a CRD/manifest cross-reference question, closer to this PR's actual k8s-manifest logic) also didn't pan out — the real implementation path for that specific question turned out to be pure Go/SQL, never touching YAML/CRD manifests at all, so it didn't end up exercising this PR's capability either. The underlying engineering here is real and correct (2 rounds of review, 9 regression tests, 4398 tests passing) and could be revived if a genuine use case shows up organically later — but shipping it now would mean carrying its real corpus-scale cost (+18% nodes even with the vendor exclusion) for a benefit that's been tested for twice and not found. #2 (the narrower GitHub Actions extractor) merged separately on its own proven merits. |

What
k8s-manifest-specific layer (
graphify/extractors/k8s_manifest.py) -- the ticket's original scope: recognizes real Kubernetes resources (apiVersion+kind+metadata, value-validated, not just key presence) and extracts:metadata.ownerReferences->ownsedges.osac.openshift.io/owner-reference= parent's ID,osac.openshift.io/tenant= tenant scoping) -- confirmed againstosac/.claude/rules/architecture-patterns.mdand the operator's own Go source (subnet_type.pb.goet al: the annotation value is the parent's ID, not name).configMapKeyRef/secretKeyRef,envFrom, volume mounts) via a generic recursive walk ofspec.*Ref/*RefsCRD cross-references (e.g.subnetRef,securityGroupRefs) -- a real, live convention confirmed againstosac-operator/config/samples/osac_v1alpha1_computeinstance.yaml, not invented.osac-operator/config/console-proxy/{service,deployment}.yaml); documented as an approximation for multi-key selectors.Direction change (confirmed explicitly mid-implementation)
Per discussion on PR #2, the scope broadened from k8s-only to universal YAML/JSON coverage: any YAML or JSON that doesn't match a recognized schema now gets a generic structural walk (
graphify/extractors/yaml_generic.py,graphify/extractors/json_generic.py-- one node per key/list item, no domain semantics) instead of staying invisible, accepting lower-value/noisier nodes in exchange for nothing being invisible. Layered viagraphify/extractors/yaml_dispatch.py(try k8s shape, else generic, per-document -- a single file can bundle multiple----separated resources, confirmed against a real file,osac-operator/config/manager/manager.yaml).extract_json()gained the same layering for data JSON.detect.pynow routes ALL.yaml/.ymltoFileType.CODEunconditionally, matching.json's existing precedent.Templated YAML safety, checked empirically rather than assumed: a real Go-templated Helm chart file (
osac-operator/charts/operator/templates/metrics-service.yaml) parses to a tree-sitter rootERRORnode, not a best-effort partial tree. The dispatcher checks.has_errorand a raw{{marker per document (see "Fixed in review" below for why both are needed) and skips with a one-line warning naming the file -- never crashes, never walks garbage.Fixed in review
Two real bugs found by review, both reproduced empirically before fixing and verified after:
extract_k8s_resources()once per document instead of once per file, defeating the two-pass same-file design the module's own comments claimed -- each document got an emptylocal_nidsscope, so a same-file forward reference (Namespace declared before the Deployment it owns) was never visible. Fixed both:_resolve_owner()now tries cluster scope for well-known cluster-scoped kinds (and falls back to trying both scopes otherwise), and the dispatcher now classifies every document first, then extracts all k8s-shaped documents in a file together in one call.replicas: {{ .Values.x }}(the single most common Helm idiom) parsed withhas_error=Falseon the specific document node checked --{{looks like valid, if bogus, nested flow-mapping syntax to the grammar, not a parse error -- so it was silently extracted as a "clean" resource.image: {{ .Values.x }}:{{ .Values.y }}sethas_error=Trueon the parse tree's stream root but not on the specific document node checked, so it silently produced zero output with no warning. Fixed by also checking each document's raw text for a literal{{marker, independent ofhas_error-- confirmed this catches both directions.New tests assert on real node-ID uniqueness (a set of ids, plus the graph actually built via
build_from_json) for the cluster-scoped-owner scenario, not label-based_rel_pairs/_labelshelpers, which are blind to two distinct node dicts sharing the same label -- exactly the shape bug 1 produced.Known interaction with PR #2 (not blocking, needs reconciling when both merge)
Verified via retest: once both PRs are combined,
detect.classify_file()ends up returningCODEfor every.yaml/.ymlunconditionally (this PR's change), which silently makes PR #2's narroweris_github_actions_workflow_path()path-based carve-out dead code -- not a textual conflict, a semantic one. Output is still correct today because the generic fallback here catches whatever PR #2's workflow-shaped extractor doesn't, but whoever merges both should explicitly remove PR #2's now-redundant carve-out rather than leave two classification paths where only one is reachable.Optional extra

Ran a true before/after against a fresh checkout of the actual
osacrepo (matching whatgraphify-brain-refresh.yamlscans), pristinev8vs this branch, same commit:This exceeds the established performance ceiling (~2.3x on nodes, ~2.6x on query wall-clock). Root-caused, not just observed: 70.3% of the new nodes (278,734) come from one vendored third-party tree,
osac-aap/vendor/ansible_collections/...-- invisible under the old YAML-is-a-document behavior, now walked in full since all YAML is unconditionally CODE. Excluding that tree arithmetically lands around ~118K nodes, comfortably under the ceiling.Decision (explicitly confirmed with the user): ship this PR as-is; the fix is a
.graphifyignorechange in theosacrepo (excluding vendored third-party trees), a corpus-scoping decision in a different repo, not a defect in this extractor.
