Summary
Implements Forgejo issue #330 -- adds 11 deferred physical resource types covering the git object taxonomy and filesystem link types to the resource registry with auto-discovery rules.
Motivation
The existing resource type system only has 4 physical types (
git-checkout,fs-directory,fs-file,fs-mount). To model the full git object graph and filesystem link topology, we need fine-grained physical types for each git object kind (remotes, branches, tags, commits, trees, tree entries, stashes, submodules) and filesystem links (symlinks, hardlinks). These types enable auto-discovery of the git object graph with bounded depth traversal.Changes
YAML Configs (
examples/resource-types/)Git object taxonomy (9 types):
git.yaml-- root git repository container; auto-discovers refs, stashes, submodules (scan_depth=2)git-remote.yaml,git-branch.yaml,git-tag.yaml-- ref types undergitgit-commit.yaml-- commit objects; auto-discovers root tree (scan_depth=1)git-tree.yaml-- tree objects; auto-discovers entries and subtrees (scan_depth=2)git-tree-entry.yaml-- leaf blob/subtree entriesgit-stash.yaml,git-submodule.yaml-- special git constructsFilesystem links (2 types):
fs-symlink.yaml-- symbolic links (read-only capabilities)fs-hardlink.yaml-- hard links (read/write capabilities)Bootstrap Registration

eb7b44273atoc80ec0bbd9PR #662 Review — Deferred Physical Resource Types
Summary
Adds 11 physical types (9 git object taxonomy + 2 filesystem links). This is the largest of the three PRs (1,507 lines, 24 files). The type taxonomy is well-designed and the extraction to
_resource_registry_physical.pyis the right call. However, there are auto-discovery issues and merge coordination concerns.P0 — Must Fix
1.
fs-directoryauto_discovery is missingscan_depthThe new auto_discovery block added to the existing
fs-directorytype definition in_resource_registry_data.pyhasenabled: Trueandrules: [...]but noscan_depthkey. Every other auto_discovery block in this PR (git: 3,git-branch: 3,git-commit: 1,git-tree: 3) includesscan_depth. If the discovery engine treats missingscan_depthas unlimited, this could cause unbounded recursive filesystem traversal.Action required: Add an explicit
scan_depth(suggest1— only immediate children) or confirm the engine has a safe default.2. Guaranteed three-way merge conflict on
BUILTIN_NAMESThis PR rewrites the entire
BUILTIN_NAMESfrozenset inresource_type.py— reordering all existing entries alphabetically and adding section comments. PRs #661 and #663 also modify this frozenset. Since this PR does the structural rewrite, it should merge first, and #661/#663 should rebase onto it.3. Three-way merge conflict on
_resource_registry_data.pySame file is touched by all three PRs (imports, BUILTIN_TYPES list tail, and in this PR also the
fs-directoryandgit-checkouttype defs in the middle of the file). This PR has the most invasive changes here — recommend it goes first.P1 — Should Fix
4.
git-branchscan_depth: 3is excessive for HEAD discoveryThe auto_discovery rule for
git-branchhasscan_depth: 3but the only rule is{"type": "git-commit", "pattern": "HEAD"}— a branch has exactly one HEAD.scan_depth: 1would be correct and more efficient. The current value won't cause bugs but misrepresents the traversal intent.5.
git-treescan_depth: 3— performance consideration for large reposRecursive tree traversal to depth 3 means the discovery engine will enumerate all blobs/subtrees up to 3 levels deep. For repos like the Linux kernel (~70k tree entries), this could be expensive during bootstrap. Consider either:
scan_depth: 1(top-level only) with opt-in deeper scanning6.
fs-directorygainsfs-mountas a new parent_typeThis is a semantic change to an existing type definition. Is this per spec or a judgment call? The PR description doesn't mention this change explicitly. Should be called out.
7.
git-checkoutgains"git"as a child_typeSimilarly, the existing
git-checkouttype is modified to include"git"in its child_types. This meansgit-checkout→git→git-branchetc. The parent-child DAG makes sense but this changes existing behavior. Should be documented in the PR description.P2 — Nice to Have
8.
git-tagchild_types deviation from specGood that the deviation is documented in a comment:
Consider opening a follow-up issue or spec amendment ticket so this deviation is tracked formally.
9.
resource_type.pyfrozenset rewrite — alphabetical sortingThe alphabetical rewrite is good for maintainability, but since it changes every line, it maximizes the merge conflict surface with #661 and #663. If you can coordinate, this should go first.

auto_discoveryfield isdict[str, Any]with two incompatible schemas and no structured validationFiles:
resource_type.py:297,_resource_registry_physical.py:27Two completely different schemas coexist in the same
dict[str, Any]field:{enabled, scan_depth, rules: [{type, pattern}]}{trigger_types: [...], scan_paths: [...]}The new model_validator (lines 457–491) does runtime dict-key probing instead of discriminated union types. Consequences:
"scna_depth": 3passes validation silently (no unknown-key rejection)enabled: Truekey is set on every new type but never validated and has no consumer in the codebase — it's dead dataRecommendation: Define
AutoDiscoveryRulesConfigandAutoDiscoveryTriggerConfigas Pydantic models. Use a discriminated union (Annotated[..., Field(discriminator=...)]) on theauto_discoveryfield. This catches typos at construction time and makes the two schemas explicit.2.
auto_discovery.rules[].typevalidated by regex format, not by existenceFile:
resource_type.py:472-476The validator checks
_BUILTIN_NAME_RE.match(rule_type)which accepts any alphanumeric-hyphen string. A rule referencing{"type": "nonexistent-type", "pattern": "..."}passes validation cleanly. Since auto-discovery rules define the traversal graph, a typo here silently creates a broken discovery chain that fails only at runtime when the handler tries to resolve the type.Recommendation: Cross-reference
rule_typeagainstBUILTIN_NAMESfor unnamespaced names. For namespaced names, the regex check is reasonable (custom types may not be loaded yet), but built-in rule targets should be membership-checked.3.
to_dict()shallow-copiesauto_discovery, sharing nested mutable referencesFile:
resource_type.py:609—result["auto_discovery"] = dict(self.auto_discovery)dict()only copies the top-level keys. The nestedruleslist (alist[dict]) shares references with the model instance. Any consumer that mutates the returned dict'srules(e.g., appending a rule, modifying a pattern) corrupts the domain model instance in-place.Recommendation: Use
copy.deepcopy(self.auto_discovery)orjson.loads(json.dumps(self.auto_discovery)). The same pattern is already used forequivalence(which does per-key copying), soauto_discoveryshould get equivalent treatment.P2 — Medium Severity
4.
git-treeself-referential parent/child with no model-level recursion guardFile:
_resource_registry_physical.py:185-186git-treelists itself in bothparent_typesandchild_types. This is semantically correct (trees contain subtrees), but the domain model's cycle detection (ADR-042 rule 3, line 494) only checksinherits == name— it doesn't check parent/child self-loops.The only guard is
scan_depth: 2, which is an honor-system convention. There is no model-level constraint that says "if a type is self-referential in parent/child, it MUST have a bounded scan_depth." A future contributor could add another recursive type withscan_depth: 100or omit it entirely.Recommendation: Either (a) add a
recursive: boolfield and validate that recursive types requirescan_depth <= MAX_RECURSIVE_DEPTH, or (b) add a model_validator that detectsname in parent_types and name in child_typesand enforces a scan_depth cap.5. BDD test missing assertion for
git-tagas parent ofgit-commitFile:
features/resource_type_deferred_physical.feature:119-123The scenario "git-commit parents are git-branch and git" asserts
git-branchandgitbut does not assertgit-tag. Both the Python data and YAML explicitly includegit-tagas a parent with a documented spec deviation comment (S23518). The missing assertion means this deliberate deviation has no regression guard — someone could removegit-tagfrom the parent list and all tests would still pass.Recommendation: Add

fs-directory.parent_typesaddsfs-mount— asymmetric relationshipFile:
_resource_registry_data.py:184On master,
fs-directory.parent_typesis["git-checkout", "fs-directory"]. This PR adds"fs-mount". However,fs-mountdoes not appear to have a type definition inBUILTIN_TYPES(it's inBUILTIN_NAMESbut has no corresponding registration entry in the data file). This meansfs-directorydeclaresfs-mountas a parent, butfs-mounthas nochild_typeslist to reciprocate.Recommendation: Verify that
fs-mountis defined elsewhere (perhaps in a different migration or YAML). If it's not yet implemented, remove it fromparent_typesuntil the type exists, or add a TODO comment with the tracking issue.P3 — Low Severity / Nits

DEFERRED_PHYSICAL_TYPEStyped aslist[dict[str, Any]]— consistent but weakFile:
_resource_registry_physical.py:27The entire 306-line module is untyped dict literals. A key typo like
"resurce_kind"is only caught at registration time (whenResourceTypeSpec.from_config()is called), not at import time. This is consistent with the existing pattern in_resource_registry_data.pybut adds 11 more entries to the untyped surface area.This is not blocking, but worth tracking as tech debt — a
TypedDictor Pydantic model for the config shape would catch errors earlier.8. Two-schema
auto_discoverynot documented in field docstringFile:
resource_type.py:297-300The field description says "Auto-discovery rules (handler-specific configuration)" which doesn't hint at the two distinct schemas. Future contributors will see the rules-based schema and may not discover the
trigger_typesvariant until it breaks.9.
enabledfield is cargo-culted across all new auto_discovery configsFiles:
_resource_registry_physical.py(4 occurrences),_resource_registry_data.py(1 occurrence)Every auto_discovery dict sets
"enabled": Truebut no code reads this field. It's not validated in the model, not checked in the bootstrap, and not referenced in any handler. If the intent is to support disabling discovery per-type, the field needs a consumer. If not, it's misleading dead data.Summary
The overall structure is clean — module extraction is well-motivated, the git DAG taxonomy is correct, registration ordering is compatible with the lazy bootstrap, and backward compatibility with
devcontainer-instance's auto_discovery schema is preserved (the validator gracefully skips whenrulesis absent).

Verdict: REQUEST_CHANGES — The P1-1 (PR description inaccuracies) is a quick text fix. P1-2 (untyped auto_discovery) is a design concern that can be partially addressed with documentation now and a Pydantic model in follow-up. All P0s from prior rounds are resolved.

REQUEST_CHANGESThis PR adds substantial value for deferred physical resource types, but it introduces a functional regression in
ResourceTypeSpec.as_cli_dict()that can crash CLI/type rendering for existing devcontainer-styleauto_discoveryconfigs. Until that regression is fixed, merge would risk breaking previously working built-in type flows. Additional requirement-completeness and process/doc mismatches are listed below.Findings Table

as_cli_dict()crash on devcontainer auto_discoveryFixed. Replaced custom list-copy comprehension (
dict(r)on strings) withcopy.deepcopy(self.auto_discovery)which safely handles both schemas:{rules: [{"type": ..., "pattern": ...}]}(list of dicts){trigger_types: [...], scan_paths: [...]}(lists of strings)Added 2 regression test scenarios:
as_cli_dict works for rules-based auto_discovery(git type)as_cli_dict works for trigger-based auto_discovery(devcontainer-instance)F-002 (P1): Missing docs update
Fixed. Added all 11 deferred physical types to

_resource_registry_cloud.pyat 754 linesDocumented exception. The file contains 36 AWS type definitions that all depend on the
_aws_type()helper function defined in the same file. Splitting mid-file would break this pattern. Added a docstring note explaining the overage and tracking the follow-up extraction.4005e3b9bbtoe2f90ffcd5New commits pushed, approval review dismissed automatically according to repository settings
