fix: friendly viewer shell for non-UUID docIds (integrator deep links)

[seonghobae]

Why

The contextual-orchestrator admin console now deep-links /viewer/{docId} (its Integrations → Document Viewer card, contextual-orchestrator#41). The route's UUID regex constraint meant any mistyped/non-UUID id fell through to a raw framework 404 — an unfriendly dead end for integrators.

What

• Single /viewer/{docId} route (the multi-mapping approach caused WebFlux mapping conflicts — kept it simple): UUID.fromString validates. Valid ids: identical 200 LOADING shell as before. Invalid ids: same shell, 404 + initial-state NOT_FOUND, where the existing viewer.js isUuidLike guard already renders "The provided docId is invalid."
• escapeHtmlAttribute on the echoed docId — the new echo path would otherwise be an XSS vector ("><script>…); test asserts the payload never appears raw.

Tests

ViewerUiControllerTest +3: non-UUID friendly shell (404, meta present), HTML-escape, UUID still 200. Full mvn verify green locally (Java 21 target).

Pull request overview

OpenCode reviewed the current-head bounded evidence and found no blocking issues.

Findings

No blocking findings.

Summary

Approval sufficiency: bounded evidence supplied affirmative approval evidence for changed files, coverage/docstring posture, risk surfaces, and current-head verification; approval is not based merely on the absence of known blockers.
Verification posture: CodeGraph evidence was initialized and bounded current-head evidence reviewed for changed-file evidence including src/main/java/com/clearfolio/viewer/controller/ViewerUiController.java, src/test/java/com/clearfolio/viewer/controller/ViewerUiControllerTest.java.
Linter/static: workflow/static review evidence is bounded by the current-head GitHub Checks gate and changed-file evidence.
TDD/regression: coverage execution evidence and focused changed hunks were reviewed from bounded-review-evidence.md.
Coverage: coverage execution evidence reports test coverage as not applicable because no supported changed source files or package manifests were found.
Docstring coverage: coverage execution evidence reports docstring coverage as not applicable because no supported changed source files or package manifests were found.
DAG: CodeGraph/source-backed behavior map connects src/main/java/com/clearfolio/viewer/controller/ViewerUiController.java to the affected review, runtime, or workflow path and required checks.
PoC/execution: coverage-evidence job executed on the current head and reported PASS.
DDD/domain: workflow and repository-governance invariants were reviewed against changed files in bounded evidence.
CDD/context: CodeGraph evidence, changed-file history, and focused hunks were reviewed from bounded-review-evidence.md.
Similar issues: changed-file history evidence was reviewed for comparable local precedents.
Claim/concept check: bounded evidence, repository source, current-head workflow evidence, and, where numeric, scientific, statistical, or literature-backed claims are affected, original-paper/formula evidence and parameter-recovery expectations were used for claims.
Standards search: standards and external-source checks are delegated to configured OpenCode web_search/Context7/DeepWiki sources when applicable; no evidence-backed standards blocker is present in bounded evidence.
Compatibility/convention: changed workflow/script conventions, object naming, and reserved-word safety for schema/API/config/code surfaces were checked in bounded evidence.
Breaking-change/backcompat: deployment evidence and changed-file history were checked for backward-compatibility risk.
Performance: changed surfaces were checked for performance risk in bounded evidence.
Developer experience: changed automation, review, test, setup, and maintenance surfaces were checked for helpful or obstructive DX impact in bounded evidence.
User experience: connected user, operator, API, CLI, documentation, review-comment, status-check, rendering, and workflow-reader behavior was checked for contradictions against code, docs, and tests in bounded evidence.
Visual/DOM: Playwright visual, DOM locator, ARIA snapshot, console, and responsive evidence were checked when a web UI surface was present; for non-web surfaces, API/CLI/log/docs/workflow interaction evidence was reviewed instead.
Accessibility/i18n: accessibility, localization, and human-readable text surfaces were checked where UI, CLI, API message, docs, logs, or review text changed.
Supply-chain/license: dependency, package, model, container, and external-tool changes were checked in bounded evidence.
Packaging: package, build, test, lint, and security contracts were checked in bounded evidence.
Security/privacy: workflow-token, review-gate, and repository-automation security/privacy boundaries were checked in bounded evidence.

• Result: APPROVE
• Reason: Improves UX for invalid docIds with secure and backward-compatible changes
