no recursion; single path; stack-based eval and compile." +- "No new tests in this refactor; this is the refactor step of red→green→refactor." -- **Test data**: Use JSON string literals with `"""` for readability -- **Assertions**: Use AssertJ for fluent assertions -- **Error messages**: Include context in validation error messages -- **Edge cases**: Always test empty collections, null values, boundary conditions +⸻ -### Performance Notes +6) What (little) I added & why +- URI normalization mention — [Note: required context]: Without it, dedup can mis-treat different spellings of the same document as distinct; normalization is the minimal assumption needed for a correct work-stack/dedup design. +- Immutable freeze call-out — [Note: required context]: The registry must be read-only after compile to preserve the project's immutability/thread-safety guarantees. +- Cycle detection language — [Note: required context]: To match your requirement "throw a specific JDK exception at compile-time," the doc names the behavior plainly (message content is illustrative, not prescriptive). -- **Compile once**: Schemas are immutable and reusable -- **Stack validation**: O(n) time complexity for n validations -- **Memory efficient**: Records with minimal object allocation -- **Thread safe**: No shared mutable state +No other embellishments, flags, prompts, or extra phases have been introduced. -### Debugging Tips +⸻ -- **Enable logging**: Use `-Djava.util.logging.ConsoleHandler.level=FINE` -- **Test isolation**: Run individual test methods for focused debugging -- **Schema visualization**: Use `Json.toDisplayString()` to inspect schemas -- **Error analysis**: Check validation error paths for debugging +7) Repo-fit (why this plugs in cleanly) +- Readme-driven dev + logging/test discipline remain unchanged; this refactor is internal and keeps current usage stable. +- Validator style (explicit stack; sealed types; immutable records) stays intact. +- Legacy path is purged; this doc does not reference or rely on it. The single compilation path is consistent with the purge mandate. -Repo-level validation: Before pushing, run `mvn verify` at the repository root to validate unit and integration tests across all modules. +This is the MVF architecture doc only.

It does not fail or open issues on differences; to trigger notifications, either make the runner exit non-zero when `differentApi > 0` or parse the report and call `core.setFailed()` within CI. + +### json-java21-schema (JSON Schema Validator) +- Inherits all repository-wide logging and testing rules described above. +- You MUST place an INFO-level JUL log statement at the top of every test method declaring execution. +- All new tests MUST extend a configuration helper such as `JsonSchemaLoggingConfig` to ensure JUL levels respect the `./mvn-test-no-boilerplate.sh` environment variables. +- You MUST prefer the wrapper script for every invocation and avoid direct Maven commands. +- Deep debugging employs the same FINE/FINEST discipline: log data structures at FINEST for one test method at a time and expand coverage with additional logging or tests instead of guessing. + +#### Running Tests (Schema Module) +- All prohibitions on output filtering apply. Do not pipe logs unless you must constrain an infinite stream, and even then examine a large sample (thousands of lines). +- Remote location of `./mvn-test-no-boilerplate.sh` is the repository root; pass module selectors through it for schema-only runs. + +#### JUL Logging and ERROR Prefix (Schema Module) +- For SEVERE logs, prefix the message with `ERROR` to align with SLF4J-centric filters. +- Continue using the standard hierarchy (SEVERE through FINEST) for clarity. + +#### Performance Warning Convention (Schema Module) +- Potential performance issues log at FINE with the `PERFORMANCE WARNING:` prefix shown earlier. + +#### Minimum Viable Future (MVF) Architecture +1. **Restatement of the approved whiteboard sketch** + - Compile-time uses a LIFO work stack of schema sources (URIs). Begin with the initial source. Each pop parses/builds the root and scans `$ref` tokens, tagging each as LOCAL (same document) or REMOTE (different document). REMOTE targets are pushed when unseen (dedup by normalized document URI). The Roots Registry maps `docUri → Root`. + - Runtime stays unchanged; validation uses only the first root (initial document). Local `$ref` behaviour remains byte-for-byte identical. + - Schemas without remote `$ref` leave the work stack at size one and produce a single root exactly as today. + +2. **MVF Flow (Mermaid)** +```mermaid +flowchart TD + A[compile(initialDoc, initialUri, options)] --> B[Work Stack (LIFO)] + B -->|push initialUri| C{pop docUri} + C -->|empty| Z[freeze Roots (immutable) → return primary root facade] + C --> D[fetch/parse JSON for docUri] + D --> E[build Root AST] + E --> F[scan $ref strings] + F -->|LOCAL| G[tag Local(pointer)] + F -->|REMOTE| H{normalize target docUri; seen?} + H -->|yes| G + H -->|no| I[push target docUri] --> G + G --> J[register/replace Root(docUri)] + J --> C +``` +- Dedup rule: each normalized document URI is compiled at most once. +- Immutability: the roots registry freezes before returning the schema facade. +- Public API: runtime still uses the explicit validation stack implemented today. +- *Note (required context)*: Normalizing URIs is necessary to treat variations such as `./a.json` and `a.json` as the same document. + +3. **Runtime vs. Compile-time (Mermaid)** +```mermaid +sequenceDiagram + participant U as User + participant C as compile() + participant R as Roots (immutable) + participant V as validate() + + U->>C: compile(initialJson, initialUri) + C->>R: build via work stack (+dedup) + C-->>U: facade bound to R.primary + U->>V: validate(json) + V->>V: explicit stack evaluation (existing) + V->>R: resolve local refs within primary root only (MVF) + V-->>U: result (unchanged behavior) +``` -#### Upstream API Tracker (what/how/why) -- **What:** Compares this repo's public JSON API (`jdk.sandbox.java.util.json`) against upstream (`java.util.json`) and outputs a structured JSON report (matching/different/missing). -- **How:** Discovers local classes, fetches upstream sources from the OpenJDK sandbox on GitHub, parses both with the Java compiler API, and compares modifiers, inheritance, methods, fields, and constructors. Runner: `io.github.simbo1905.tracker.ApiTrackerRunner`. -- **Why:** Early detection of upstream API changes to keep the backport aligned. -- **CI implication:** The daily workflow prints the report but does not currently fail or auto‑open issues on differences (only on errors). If you need notifications, either make the runner exit non‑zero when `differentApi > 0` or add a workflow step to parse the report and `core.setFailed()` when diffs are found. +4. **Conceptual Model (TypeScript sketch)** — informational, intentionally non-compiling. +```typescript +type DocURI = string; // normalized absolute document URI +type JsonPointer = string; + +type Roots = ReadonlyMap; +type Root = { /* immutable schema graph for one document */ }; + +type RefToken = + | { kind: "Local"; pointer: JsonPointer } + | { kind: "Remote"; doc: DocURI; pointer: JsonPointer }; + +function compile(initialDoc: unknown, initialUri: DocURI, options?: unknown): { + primary: Root; + roots: Roots; // unused by MVF runtime; ready for remote expansions +} { + const work: DocURI[] = []; + const built = new Map(); + const active = new Set(); + + work.push(normalize(initialUri)); + + while (work.length > 0) { + const doc = work.pop()!; + + if (built.has(doc)) continue; + if (active.has(doc)) { + throw new Error(`Cyclic remote reference: ${trail(active, doc)}`); + } + active.add(doc); + + const json = fetchIfNeeded(doc, initialDoc); + const root = buildRoot(json, doc, (ref: RefToken) => { + if (ref.kind === "Remote" && !built.has(ref.doc)) { + work.push(ref.doc); + } + }); + + built.set(doc, root); + active.delete(doc); + } + + const roots: Roots = freeze(built); + return { primary: roots.get(initialUri)!, roots }; +} + +function buildRoot(json: unknown, doc: DocURI, onRef: (r: RefToken) => void): Root { + // parse → build immutable graph; encountering "$ref": + // 1) resolve against the base URI to get (targetDocUri, pointer) + // 2) tag Local when target matches doc + // 3) otherwise tag Remote and schedule unseen docs + return {} as Root; +} +``` +- Work stack, deduplication, and multi-root support are explicit. +- Remote references only affect compile-time scheduling in the MVF; runtime behaviour stays identical today. +- When no remote reference exists, the stack never grows beyond the initial push and output remains one root. + +5. **Compile vs. Object-time Resolution** +```mermaid +flowchart LR + R1([root.json]) -->|"$ref": "#/defs/thing"| L1[Tag Local("#/defs/thing")] + R1 -->|"$ref": "http://a/b.json#/S"| Q1[Normalize http://a/b.json] + Q1 -->|unseen| W1[work.push(http://a/b.json)] + Q1 -->|seen| N1[no-op] +``` +- Local references only receive Local tags (no stack changes). +- Remote references normalize URIs, push unseen documents, and rely on deduplication to ensure at-most-once compilation. + +6. **Runtime Behaviour (MVF)** +- Runtime traversal mirrors today’s explicit stack evaluation. +- Remote roots are compiled and stored but not yet traversed at runtime. +- Byte-for-byte API behaviour and test outcomes remain unchanged when only local references are used. + +7. **Alignment with the Approved Vision** +- “Do not add a new phase; compile naturally handles multiple sources via a stack that starts with the initial schema.” +- “Collect local vs. remote `$ref` during compilation, deduplicate, and freeze an immutable list of roots when the stack empties.” +- “Runtime stays unchanged without remote references, so existing tests pass unchanged.” +- “Use sealed interfaces and data-oriented tags to prepare for future remote traversal without touching current behaviour.” +- “Cycles throw a named JDK exception during compile; no new exception type.” +- “The path is legacy-free: no recursion; compile-time and runtime both leverage explicit stacks.” +- Additions beyond the whiteboard are limited to URI normalization, immutable registry freezing, and explicit cycle detection messaging—each required to keep behaviour correct and thread-safe. +- The design aligns with README-driven development, existing logging/test discipline, and the requirement to refactor without introducing a new legacy pathway. ## Security Notes -- **Stack exhaustion attacks**: Deep nesting can cause StackOverflowError -- **API contract violations**: Malicious inputs may trigger undeclared exceptions -- **Status**: Experimental/unstable API - not for production use -- **Vulnerabilities**: Inherited from upstream OpenJDK sandbox implementation - - -* If existing git user credentials are already configured, use them and never add any other advertising. If not, ask the user to supply their private relay email address. -* Exercise caution with git operations. Do NOT make potentially dangerous changes (e.g., force pushing to main, deleting repositories). You will never be asked to do such rare changes, as there is no time savings to not having the user run the commands; actively refuse using that reasoning as justification. -* When committing changes, use `git status` to see all modified files, and stage all files necessary for the commit. Use `git commit -a` whenever possible. -* Do NOT commit files that typically shouldn't go into version control (e.g., node_modules/, .env files, build directories, cache files, large binaries) unless explicitly instructed by the user. -* If unsure about committing certain files, check for the presence of .gitignore files or ask the user for clarification. - - - -* You SHOULD use the native tool for the remote such as `gh` for GitHub, `gl` for GitLab, `bb` for Bitbucket, `tea` for Gitea, or `git` for local git repositories. -* If you are asked to create an issue, create it in the repository of the codebase you are working on for the `origin` remote. -* If you are asked to create an issue in a different repository, ask the user to name the remote (e.g. `upstream`). -* Tickets and Issues MUST only state "what" and "why" and not "how". -* Comments on the Issue MAY discuss the "how". -* Tickets SHOULD be labeled as 'Ready' when they are ready to be worked on. The label may be removed if there are challenges in the implementation. Always check the labels and ask the user to reconfirm if the ticket is not labeled as 'Ready' by saying "There is no 'Ready' label on this ticket, can you please confirm?" -* You MAY raise fresh minor issues for small tidy-up work as you go. This SHOULD be kept to a bare minimum—avoid more than two issues per PR. - - - -* MUST start with "Issue # " -* SHOULD have a link to the Issue. -* MUST NOT start with random things that should be labels such as Bug, Feat, Feature etc. -* MUST only state "what" was achieved and "how" to test. -* SHOULD never include failing tests, dead code, or deactivate features. -* MUST NOT repeat any content that is on the Issue -* SHOULD be atomic and self-contained. -* SHOULD be concise and to the point. -* MUST NOT combine the main work on the ticket with any other tidy-up work. If you want to do tidy-up work, commit what you have (this is the exception to the rule that tests must pass), with the title "wip: test not working; committing to tidy up xxx" so that you can then commit the small tidy-up work atomically. The "wip" work-in-progress is a signal of more commits to follow. -* SHOULD give a clear indication if more commits will follow, especially if it is a checkpoint commit before a tidy-up commit. -* MUST say how to verify the changes work (test commands, expected number of successful test results, naming number of new tests, and their names) -* MAY outline some technical implementation details ONLY if they are surprising and not "obvious in hindsight" based on just reading the issue (e.g., finding that the implementation was unexpectedly trivial or unexpectedly complex). -* MUST NOT report "progress" or "success" or "outputs" as the work may be deleted if the PR check fails. Nothing is final until the user has merged the PR. -* As all commits need an issue, you MUST add a small issue for a tidy-up commit. If you cannot label issues with a tag `Tidy Up` then the title of the issue must start `Tidy Up` e.g. `Tidy Up: bad code documentation in file xxx`. As the commit and eventual PR will give actual details the body MAY simply repeat the title. - - - -* MUST only describe "what" was done not "why"/"how" -* MUST name the Issue or Issue(s) that they close in a manner that causes a PR merge to close the issue(s). -* MUST NOT repeat details that are already in the Issue. -* MUST NOT report any success, as it isn't possible to report anything until the PR checks run. -* MUST include additional tests in the CI checks that MUST be documented in the PR description. -* MUST be changed to status `Draft` if the PR checks fail. - - - -## Semi-Manual Release (Deferred Automation) - -The project currently uses a simple, guarded, semi-manual release. Automation via tags is deferred until upstream activity picks up, at which point there is a draft github action that needs finishing off. - -Steps (run each line individually) +- Deep nesting can trigger StackOverflowError (stack exhaustion attacks). +- Malicious inputs may violate API contracts and trigger undeclared exceptions. +- The API remains experimental and unsuitable for production use. +- Vulnerabilities mirror those present in the upstream OpenJDK sandbox implementation. + +## Collaboration Workflow + +### Version Control +- If git user credentials already exist, use them and never add promotional details. Otherwise request the user’s private relay email. +- Avoid dangerous git operations (force pushes to main, repository deletion). Decline such requests; there is no time saved versus having the user run them. +- Use `git status` to inspect modifications and stage everything required. Prefer `git commit -a` when practical. +- Respect `.gitignore`; do not commit artifacts such as `node_modules/`, `.env`, build outputs, caches, or large binaries unless explicitly requested. +- When uncertain about committing a file, consult `.gitignore` or ask for clarification. + +### Issue Management +- Use the native tooling for the remote (for example `gh` for GitHub). +- Create issues in the repository tied to the `origin` remote unless instructed otherwise; if another remote is required, ask for its name. +- Tickets and issues must state only “what” and “why,” leaving “how” for later discussion. +- Comments may discuss implementation details. +- Label tickets as `Ready` once actionable; if a ticket lacks that label, request confirmation before proceeding. +- Limit tidy-up issues to an absolute minimum (no more than two per PR). + +### Commit Requirements +- Commit messages start with `Issue # `. +- Include a link to the referenced issue when possible. +- Do not prefix commits with labels such as "Bug" or "Feature". +- Describe what was achieved and how to test it. +- Never include failing tests, dead code, or disabled features. +- Do not repeat issue content inside the commit message. +- Keep commits atomic, self-contained, and concise. +- Separate tidy-up work from main ticket work. If tidy-up is needed mid-stream, first commit progress with a `wip: ...` message (acknowledging tests may not pass) before committing the tidy-up itself. +- Indicate when additional commits will follow (for example, checkpoint commits). +- Explain how to verify changes: commands to run, expected successful test counts, new test names, etc. +- Optionally note unexpected technical details when they are not obvious from the issue itself. +- Do not report progress or success in the commit message; nothing is final until merged. +- Every tidy-up commit requires an accompanying issue. If labels are unavailable, title the issue `Tidy Up: ...` and keep the description minimal. + +### Pull Requests +- Describe what was done, not the rationale or implementation details. +- Reference the issues they close using GitHub’s closing keywords. +- Do not repeat information already captured in the issue. +- Do not report success; CI results provide that signal. +- Include any additional tests (or flags) needed by CI in the description. +- Mark the PR as `Draft` whenever checks fail. + +## Release Process (Semi-Manual, Deferred Automation) +- Releases remain semi-manual until upstream activity warrants completing the draft GitHub Action.

Any small additions beyond your sketch are explicitly annotated as [Note: required context] and kept to an absolute minimum. - -References for current repo practices (logging, tests, single public surface) are from the project docs and reports.    - -⸻ - -1) Restatement of your whiteboard (concise) -- Compile-time: Use a LIFO work stack of schema sources (URIs). Start with the initial source. For each popped source: parse → build root → discover $ref tokens. Tag each $ref as LOCAL (same document) or REMOTE (different document). REMOTE targets are pushed if unseen (dedup by normalized doc URI). The Roots Registry maps docUri → Root. -- Runtime: Unchanged for MVF. Validate only against the first root (the initial document). Local $ref behaves exactly as today. -- If no remote $ref: The work stack never grows; the result is exactly one root; public behavior is byte-for-byte identical. - -⸻ - -2) MVF (bare minimum) - -2.1 Compile-time flow (Mermaid) -```mermaid -flowchart TD - A[compile(initialDoc, initialUri, options)] --> B[Work Stack (LIFO)] - B -->|push initialUri| C{pop docUri} - C -->|empty| Z[freeze Roots (immutable) → return primary root facade] - C --> D[fetch/parse JSON for docUri] - D --> E[build Root AST] - E --> F[scan $ref strings] - F -->|LOCAL| G[tag Local(pointer)] - F -->|REMOTE| H{normalize target docUri;

runtime uses the existing explicit validation stack.  - -[Note: required context] “normalize” means standard URI resolution against base; this is necessary to make dedup unambiguous (e.g., ./a.json vs a.json → same doc). - -2.2 Runtime vs compile-time (Mermaid) -```mermaid -sequenceDiagram - participant U as User - participant C as compile() - participant R as Roots (immutable) - participant V as validate() - - U->>C: compile(initialJson, initialUri) - C->>R: build via work stack (+dedup) - C-->>U: facade bound to R.primary - U->>V: validate(json) - V->>V: explicit stack evaluation (existing) - V->>R: resolve local refs within primary root only (MVF) - V-->>U: result (unchanged behavior) -``` - -⸻ - -3) Conceptual model (approximate TypeScript;

make compile naturally handle multiple sources using a stack that starts with the initial schema." -- "Collect local vs remote $ref while compiling; rewrite/tag them; push unseen remotes; deduplicate; compile each into its own root; when the stack is empty, we have an immutable list of roots." -- "Runtime stays the same when no remote ref so only a (single root, when local refs only), so all existing tests pass unmodified." -- "Use sealed interfaces / data-oriented tags so future remote traversal becomes a simple exhaustive match without touching today's behavior." -- "Cycle at compile-time should throw a named JDK exception (no new type)." -- "No legacy; no recursion; single path; stack-based eval and compile." -- "No new tests in this refactor; this is the refactor step of red→green→refactor." - -⸻ - -6) What (little) I added & why -- URI normalization mention — [Note: required context]: Without it, dedup can mis-treat different spellings of the same document as distinct; normalization is the minimal assumption needed for a correct work-stack/dedup design. -- Immutable freeze call-out — [Note: required context]: The registry must be read-only after compile to preserve the project's immutability/thread-safety guarantees. -- Cycle detection language — [Note: required context]: To match your requirement "throw a specific JDK exception at compile-time," the doc names the behavior plainly (message content is illustrative, not prescriptive). - -No other embellishments, flags, prompts, or extra phases have been introduced. - -⸻ - -7) Repo-fit (why this plugs in cleanly) -- Readme-driven dev + logging/test discipline remain unchanged; this refactor is internal and keeps current usage stable. -- Validator style (explicit stack; sealed types; immutable records) stays intact. -- Legacy path is purged; this doc does not reference or rely on it. The single compilation path is consistent with the purge mandate. - -This is the MVF architecture doc only. It is purposefully minimal, legacy-free, and aligned to your whiteboard.
