test(#139): improve cmd/review-bot coverage from 44.6% to 49.3%

Add tests for previously uncovered paths:

- TestIsValidateError_Nil: isValidateError(nil, ...) returns false
- TestValidateURL_EmptyHost: URL with no hostname (https://) → code-2 error
- TestRunValidateURL_Success: success path (OK output + exit 0) via example.com
- TestMainSubprocess_MissingLLMBaseURL: --llm-base-url required for openai provider
- TestMainSubprocess_MissingAICoreCredentials: aicore creds required for provider=aicore
- TestMainSubprocess_ConflictingPersonaFlags: --persona and --persona-file are mutually exclusive
- TestMainSubprocess_DeprecatedGiteaURLEnv: GITEA_URL env var emits deprecation warning

All tests pass; no production code changes; dep check clean.

+# CHANGELOG
+
+## Unreleased
+
+### Added
+
+- **`doc-map` input** (`--doc-map` flag / `DOC_MAP_FILE` env var): Path to a YAML file mapping source path globs to governing design docs. review-bot intersects the map with changed PR paths and injects matching docs into the system prompt under a `## Design Documents` heading. ([#137](https://gitea.weiker.me/rodin/review-bot/issues/137))
+- **`doc-map-max-bytes` input** (`--doc-map-max-bytes` flag / `DOC_MAP_MAX_BYTES` env var): Cap on total injected design doc content in bytes. Default: 102400 (100 KB). Prevents accidental context overflow when a PR touches many modules.
+- **`DesignDocs` budget section**: Design docs are included in the context budget and trimmed after conventions, before file context, if the total exceeds the model's context limit.
+
+### Doc-map config format
+
+```yaml
+mappings:
+  - paths:
+      - "lib/gargoyle/engine/signal_risk/**"
+    docs:
+      - docs/domain/contexts/risk/risk-controls.md
+  - paths:
+      - "lib/gargoyle/trading/**"
+    docs:
+      - docs/domain/contexts/trading/
+```
+
+- `paths` — glob patterns (including `**`) matched against changed file paths in the PR
+- `docs` — local file paths or directories (all `.md` files under a directory) to inject
+- Multiple mappings can reference the same doc; docs are deduplicated
+- Missing doc files: warn and skip (review continues without them)
+- No matching paths: no docs injected, review runs normally
+- Absolute paths and path traversal (`..` segments) in doc paths are rejected
+
+### Security
+
+- **Path traversal guard**: doc paths from the YAML config are validated to reject absolute paths and `..` segments before VCS API calls
+- **Prompt injection guard**: design doc content is injected with an explicit instruction to treat it as reference data and not follow any instructions it may contain
+
+## v0.3.2
+
+- Previous releases tracked in Gitea release notes.

-### Verdict: NEEDS_WORK
-
-- [x] [completeness] `VCS_TYPE` env var is detected in `main.go` but **not passed from `action.yml`'s `Run review` step** to the binary. The binary falls back to a URL heuristic (`github.com` / `github.concur.com` substrings), which will silently misclassify any GitHub Enterprise Server whose hostname does not contain `github`. The action already has `vcs_type` as a step output — it should be passed as `VCS_TYPE: ${{ steps.version.outputs.vcs_type }}` in the `Run review` env block.
-- [x] [completeness] `README.md` still references `GITEA_REPO` and `$GITEA_TOKEN` in the CLI example (line ~288) and the env var table (line ~303). Now that the binary supports GitHub too, these should be renamed to VCS-agnostic names (`VCS_REPO`/`REPO`, `VCS_TOKEN`/`REVIEWER_TOKEN`) or at minimum the env var table should note GitHub support.
-- [x] [fit] `vcsReviewComment.NewPosition` field comment says "Gitea: absolute line; GitHub: diff hunk position" but in `githubVCSAdapter.PostReview` it is actually mapped to `Line` (absolute line) + `Side: "RIGHT"`, not to `Position` (hunk position). The field name and comment are now slightly misleading — the field means "new line number" for Gitea and is repurposed as "absolute line" for GitHub. Consider renaming to `Line` or `NewLine` with a clearer comment explaining the per-backend semantics.
-- [x] [instinct] `validateurl.go` imports `gitea` package for `gitea.IsBlockedIP` — this creates a dependency from the GitHub-generic `validateurl.go` on the Gitea-specific package. The `IsBlockedIP` function is a general networking utility. Consider moving it to a shared `internal/netutil` package (or keeping it in `gitea` and accepting the coupling), but the current import is an unexpected relationship.

+# Design: doc-map input for path-scoped design doc injection (Issue #137)
+
+## Problem
+
+review-bot can inject context via `patterns-repo` (external VCS repos) and `conventions-file`
+(a single file from the reviewed repo). There is no mechanism to inject local repo documentation
+files scoped to the paths changed in a PR.
+
+First consumer: `grgl/gargoyle#778` needs a "doc adherence" reviewer that checks code against the
+module's governing design doc, without injecting every doc in the tree.
+
+## Approach
+
+### New: `doc-map` input
+
+A `.review-bot/doc-map.yml` config file in the reviewed repo maps source path globs to governing
+design docs. review-bot reads the map, intersects it with changed PR paths, and injects only the
+relevant docs into the system prompt.
+
+### Config format
+
+```yaml
+mappings:
+  - paths:
+      - "lib/gargoyle/engine/signal_risk/**"
+    docs:
+      - docs/domain/contexts/risk/risk-controls.md
+  - paths:
+      - "lib/gargoyle/trading/**"
+    docs:
+      - docs/domain/contexts/trading/
+```
+
+- `paths` — glob patterns (including `**`) matched against changed file paths in the PR
+- `docs` — file paths or directory paths (all `.md` files under a directory) to inject
+- Docs are deduplicated across mappings
+
+### Architecture
+
+| Component | Description |
+|-----------|-------------|
+| `review/docmap.go` | YAML parsing, glob matching with `**` support, doc loading via VCS |
+| `cmd/review-bot/main.go` | Step 6c: parses config, intersects with changed files, calls LoadMatchingDocs |
+| `budget/budget.go` | New `DesignDocs` section — injected after Conventions in system prompt |
+| `action.yml` | `doc-map` and `doc-map-max-bytes` inputs, wired to `DOC_MAP_FILE`/`DOC_MAP_MAX_BYTES` |
+
+### Doc file loading
+
+- The `doc-map` YAML file is read from the local workspace (like `system-prompt-file`).
+- Doc files listed in the config are fetched via VCS API (same as `conventions-file`),
+  enabling them to be loaded from any branch without a local checkout.
+- `GetAllFilesInPath` is tried first; if it returns files, they are treated as a directory listing.
+  If it returns empty, `GetFileContent` is tried as a fallback (single file).
+
+### Glob matching
+
+`**` is implemented by splitting patterns and paths on `/`, then matching segment-by-segment.
+A `**` segment consumes zero or more path segments (not just one level like `*`).
+
+### Budget integration
+
+`DesignDocs` is added to `budget.Sections` between `Conventions` and `FileContext`.
+Trim order: Patterns → Conventions → DesignDocs → FileContext → Diff.
+Design docs appear in the system prompt under `## Design Documents`.
+
+### Context size guard
+
+Default: 100 KB. Configurable via `--doc-map-max-bytes` / `DOC_MAP_MAX_BYTES`.
+Truncation is noted inline with a `⚠️` message.
+
+## Error handling
+
+| Situation | Behavior |
+|-----------|----------|
+| `--doc-map` file not found | Fatal error (like `--system-prompt-file`) |
+| `--doc-map` file invalid YAML | Fatal error with descriptive message |
+| Unknown YAML keys | Log warning, continue |
+| Doc file not found in VCS | Log warning, skip |
+| Doc directory empty or no `.md` files | Log debug, skip |
+| Total size exceeds limit | Truncate with notice, log warning |
+| No changed paths match any mapping | No docs injected, review runs normally |
+| `paths` or `docs` list empty in a mapping | Skip that mapping |
