- Remove unused error return from BuildPositionToLineMap (always nil)
- Add comment explaining intentional CommitID drop in PostReview
- Refactor TestAdapter_PostReview_WithComments to route by URL path
- Add TestAdapter_GetFileContent_RefRouting test
- Acknowledge maxPosition O(n) with code comment
- Remove redundant TestAdapter_CompileTimeCheck (compile-time var _ exists)
- Fix GetPullRequestFiles comment (Patch field is omitted, not 'set to empty')
- Acknowledge translateEvent fallback as intentional design
Implements the Gitea adapter (gitea.Adapter) that satisfies vcs.Client.
Key components:
- gitea/adapter.go: Adapter struct wrapping *Client with all vcs.Client methods
- gitea/position.go: BuildPositionToLineMap for diff-position → line translation
- gitea/adapter_test.go: Tests for all mapping methods and event translation
- gitea/position_test.go: Tests for position translation edge cases
Translation details:
- ReviewEvent: APPROVE → APPROVED (Gitea-native)
- PostReview: fetches diff, builds position map, translates each comment
- Deletion-targeted positions map to nearest non-deletion line below
- All field-mapping methods tested (GetPullRequest, GetPullRequestFiles,
ListReviews, GetCommitStatuses, ListContents)
Also:
- Added Base field to gitea.PullRequest struct
- Updated conformance tests to assert Adapter (not raw Client) satisfies vcs.Client
- Removed phase2 build tag from conformance tests

Closes#84, Closes#85, Closes#86
- Extract named HeadRef and UserInfo structs from anonymous structs
in PullRequest and Review (comments 16615, 16616)
- Change ReviewEventApprove value from "APPROVED" to "APPROVE" to
represent the action, not the state; document adapter translation
responsibility (comment 16621)
- Add doc comment on ReviewComment.CommitID noting optionality (16531)
- Move compile-time assertion from check.go (//go:build ignore) to
check_test.go with a "phase2" build tag — removes gitea adapter
import from the vcs package (comment 16622)
- check.go misleading comment was already fixed in prior commit (16532, 16539)
- Sha→SHA, typed ReviewEvent, duplicate package doc already resolved (16537, 16538, 16530)
Add vcs/interfaces.go and vcs/types.go as the foundation for multi-platform
VCS support. Interfaces are discovered from working gitea/client.go code,
not invented in a vacuum.
vcs/interfaces.go — role-based interfaces:
- PRReader: GetPullRequest, GetPullRequestDiff, GetPullRequestFiles
- FileReader: GetFileContent (path + ref), ListContents
- Reviewer: PostReview (ReviewRequest), ListReviews, DeleteReview
- Identity: GetAuthenticatedUser
- Client: all four composed
vcs/types.go — types extracted from gitea/:
- PullRequest, ChangedFile, ContentEntry, Review (identical to gitea/)
- ReviewComment: uses GitHub diff-position convention (Position int,
CommitID string) instead of Gitea's NewPosition int64
- ReviewRequest: new type wrapping Body, Event, Comments
vcs/check.go (//go:build ignore) — documents the gaps gitea.Client
must bridge in Phase 2:
1. PostReview signature mismatch (event+body+[]ReviewComment vs ReviewRequest)
2. GetFileContent missing ref parameter
3. ReviewComment type mismatch (NewPosition vs Position/CommitID)
No behavior changes. All existing tests pass.
Update the approved dependency table to document go-yaml subpackage
usage (ast, parser) and remove the deviation comment now that the
proper allowlist process is being followed.
Closes#91
- Clarify depth-aware short-circuit comment to unambiguously describe
the relationship between current depth and previous validation depth
- Add comment to MappingValueNode case explaining intentional depth+2
behavior from parent MappingNode perspective
- Restructure unmarshalYAMLWithDepthLimit doc comment as bullet list
covering all three safety checks (depth, multi-doc, strict fields)
- Replace t.Error with t.Fatal in TestYAMLEmptyFileRejection to remove
redundant nil guard on subsequent err.Error() call
- Add explicit case for *ast.MergeKeyNode in checkYAMLDepth switch to
make it clear this is an intentional leaf (no children to recurse)
rather than relying on the default case. Prevents future library
changes from silently bypassing depth checks.
- Add MaxPersonaFileSize bound check at the top of ParsePersonaBytes.
While callers already check size, the public API should defend itself
(defense in depth) against arbitrarily large inputs that could cause
excessive memory/CPU before AST validation runs.
- Add tests for both behaviors.
Addresses review #2879 findings.
- Add safety note on Strict() decoder not expanding aliases recursively,
since alias resolution uses the pre-validated AST (finding #1)
- Document that ast.Node map keys rely on pointer identity, which holds
because all goccy/go-yaml AST types are pointer receivers (finding #2)
- Clarify AnchorNode comment: effective depth budget is reduced for
anchor+alias pairs, not literally halved (finding #3)
- Improve test depth trace comment for accuracy (finding #4)
- Add HTML comment in CONVENTIONS.md referencing #91 for the two-step
process deviation (finding #5)
- Fix validated map comment: says 'minimum depth' but stores the maximum
depth at which a node was validated (overwritten on deeper visits).
- Replace dec.More() with explicit dec.Decode check for trailing JSON
content. More() is documented for use inside arrays/objects; the
explicit EOF check is clearer at the top-level stream.
MINOR fixes:
- docs/DESIGN-57-yaml-persona.md: fix Error Cases table entry to reflect
custom AST walk (checkYAMLDepth) instead of stale library-level reference
- review/persona.go: add EOF check after JSON decode to reject trailing
garbage after a valid JSON object (prevents silent acceptance of malformed
input like '{"name":"x"}garbage')
- review/persona_test.go: add TestJSONTrailingContentRejected test
NIT fixes:
- review/persona.go: add default case to checkYAMLDepth switch with
explanatory comment about scalar leaf nodes
- review/persona.go: document AnchorNode depth+1 conservative asymmetry
- review/persona.go: simplify redundant if-guard in ListBuiltinPersonas
- Move nodeCount increment after cycle detection to avoid over-counting
cyclic references (sonnet #2)
- Use underscores in test case names used as filenames (sonnet #3)
- Fix function comment: 'prevent silent data loss' → 'prevent confusing
behavior where additional documents are silently ignored' (sonnet #4)
- Mark design doc pseudocode as historical since implementation uses
goccy/go-yaml ast.Node, not gopkg.in/yaml.v3 yaml.Node (sonnet #5)
The global 'seen' set allowed anchored subtrees validated at a shallow
depth to be skipped when later referenced via alias at a greater depth.
This could let effective nesting exceed MaxYAMLDepth, enabling DoS.
Fix: replace the single 'seen' set with two tracking maps:
- validated (node -> min depth): only short-circuits when current depth
<= previously validated depth; re-checks at deeper contexts.
- visiting (node -> bool): per-path recursion stack for true cycle
detection (breaks alias loops without suppressing depth checks).
Add TestYAMLAliasDepthBypass that constructs a document with an
anchored 15-level subtree referenced via alias under 6 levels of
nesting, verifying the combined effective depth (22) is rejected.
Addresses security-review-bot findings on review #2774.
Fixes#87.
PR #58 incorrectly added gopkg.in/yaml.v3 (abandoned library) instead of
github.com/goccy/go-yaml as required by issue #57.
Changes:
- Replace gopkg.in/yaml.v3 with github.com/goccy/go-yaml v1.19.2
- Update review/persona.go to use goccy/go-yaml API:
- parser.ParseBytes for AST-based depth/node count checking
- yaml.Strict() decoder option instead of KnownFields(true)
- ast.Node types instead of yaml.Node for tree walking
- Update review/persona_test.go to use ast types for cycle tests
- Remove gopkg.in/yaml.v3 from go.mod and go.sum
All existing YAML tests pass with the new library.
Addresses intermittent 'unexpected end of JSON input' failures where the
LLM response body is truncated in transit between the proxy and client.
Root cause: network-level truncation where io.ReadAll returns partial data
(observed in 3/50 CI runs through HAI proxy). The response body reading
was already using io.ReadAll correctly, but transient network issues
between the proxy and client can still cause partial reads.
Changes:
- Add Content-Length validation in doRequest: detect when fewer bytes
arrive than the server declared, triggering a retry
- Add retry logic in Complete: retries once on retryable errors (body
read failures, content-length mismatches) with a 500ms backoff
- Add parse-level retry in main: if ParseResponse fails, re-requests
from the LLM once before giving up (defensive, since retries always
succeed per issue evidence)
- Improve ParseResponse error diagnostics: log raw vs cleaned lengths
and a preview of the cleaned content to aid future debugging
Does NOT retry on API errors (4xx/5xx) or structural issues — only
transient body read problems.
Closes#47
