Resolves #12304

Authored by GPT-5.5 (Codex Desktop). Session 019e7f45-ad55-75e0-bfff-a21c2385df00.
FAIR-band: over-target [20/30] — taking this lane despite over-target because the operator explicitly prioritized portal-news recovery and directed GPT to proceed on this P0 portal lane.

Switches the portal Tickets tree store onto the chunked `tickets/index.json` payload, keeps lazy folder expansion active, and preserves route usability by loading the first ticket chunk before resolving the default ticket route. Chunk folder rows now render as user-facing ticket ranges instead of exposing raw `chunk-N` labels.

Evidence: L3 (fresh no-cache local Chromium portal-route check: `index.json` requested, first chunk requested, visible ticket range labels, ticket leaf selected, article content rendered, no console/request failures) -> L3 required (portal UI/runtime AC). No residuals.

Related: #12204

## Deltas from ticket

The implementation includes a tickets-controller routing guard copied from the already chunked discussions view pattern: default route resolution and direct ticket selection now load lazy chunks when needed so the chunked store does not route to a folder record.

## Test Evidence

- `node --check apps/portal/model/Ticket.mjs`
- `node --check apps/portal/store/Tickets.mjs`
- `node --check apps/portal/view/news/tickets/MainContainerController.mjs`
- `node --check test/playwright/unit/app/content/TreeList.spec.mjs`
- `npm run test-unit -- test/playwright/unit/app/content/TreeList.spec.mjs` — 4 passed
- `npm run test-unit -- test/playwright/unit/ai/buildScripts/docs/index/TicketIndex.spec.mjs` — 1 passed
- `git diff --check` and `git diff --cached --check`
- L3 portal runtime check: loaded `/apps/portal/#/news/tickets` from a no-cache static server in Chromium; server log showed `/apps/portal/resources/data/tickets/index.json?page=1&pageSize=0` and `/apps/portal/resources/data/tickets/backlog/active-chunk-16.json`; runtime state reported `indexRequested: true`, `chunkRequested: true`, `rawChunkLabelVisible: false`, `articleHasContent: true`, `consoleErrors: []`, `failed: []`.

## Post-Merge Validation

- [ ] Verify the deployed portal Tickets tab still requests `tickets/index.json` first and fetches chunk files only when folders are opened.

# PR Review Summary

**Status:** Approved

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: Cleanly switches the tickets route to the chunked lazy index + adopts the lazy-aware controller, satisfying #12304 (incl. its explicit "raw `chunk-N` labels are not acceptable" UX contract — chunk folders render as `Tickets <start>-<end>` ranges). CI green, lazy-aware controller mirrors the proven discussions pattern, and the chunked adoption is test-pinned. The range *scheme*'s refinement (display direction, "positions vs IDs", cross-view convergence with pulls/discussions) is the operator's pending UX brainstorm — captured below as **non-blocking** notes, not blockers, since #12304 required *a* non-raw shape and this delivers + tests one. §9.0 Premise Pre-Flight: no Drop+Supersede trigger.

**Peer-Review Opening:** Thanks — this is the tickets twin of the pulls lazy-nav work and the controller mirrors the discussions lazy resolution faithfully. (Aside: your `getDefaultRouteId` `@returns {Promise<String|null>}` is correct — I missed that on the pulls sibling and will fix it there.)

### 🔬 Depth Floor

**Challenge (non-blocking, for the cross-view chunk-naming brainstorm):**
1. The range label is **positional-from-oldest** (`(chunk-N − 1)*100 + 1`), and since chunks sort newest-first the **top** folder shows the **highest** range (e.g. `Tickets 1501-1509`) while you scroll down to `1-100` — the operator's example (`"1-100"`, `"101-134"`) read as ascending-from-top.
2. `Tickets 1501-1509` is readable as ticket **IDs** but is actually a **position** range; for archive groups it's per-group-positional (`Tickets 1-9` under `v1.0.0` = that version's chunk-1, not global). Worth disambiguating in the brainstorm.
3. **Cross-view consistency:** pulls #12307 deliberately shipped opaque chunk folders pending the operator's call; approving this establishes the range scheme for the chunked views, so I'll converge #12307 to match (ranges) — flagged below.

These are scheme-refinement items for the operator's UX brainstorm; the baseline (non-raw range labels, not `chunk-N`) correctly satisfies #12304 here.

**Rhetorical-Drift Audit (per guide §7.4):**
- [x] PR title/body framing matches the diff (store url, lazy controller, range-label model, tests).
- [x] Anchor & Echo: `Ticket.mjs` treeNodeName + controller JSDoc precise; `@returns {Promise<String|null>}` correctly reflects the async signature.
- [x] No ticket-archaeology in the changed durable code.

**Findings:** Pass; range-scheme nuances flagged as non-blocking brainstorm notes.

---

### 🎯 Close-Target Audit
- [x] Close-target: `#12304` — confirmed **not** `epic`-labeled (it's a sub blocking #12219; PR uses `Resolves #12304` correctly, not the #12204 epic).

**Findings:** Pass.

---

### 📑 Contract Completeness Audit
- [x] #12304's Contract Ledger row ("Tickets tree lazy folders": expand fetches `childrenUrl` leaves on demand; failure retains parent) is honored by the lazy-aware controller + store switch.
- [x] #12304's explicit UX contract ("raw `chunk-N` labels are not a finished UI") is satisfied — chunk folders render as `Tickets <range>`.

**Findings:** Pass.

---

### N/A Audits — 🪜 📡 🔗
N/A across listed dimensions: ACs covered by unit tests (chunked store + range label + lazy default-route); no `openapi.yaml`; no skill/`AGENTS*.md`/convention surface.

---

### 🧪 Test-Execution & Location Audit
- [x] Branch checked out (`codex/12304-tickets-chunked-store`, head `ea16cd7b2`).
- [x] Ran `TreeList.spec.mjs` → **4 passed**, incl. "uses the chunked tickets index and renders chunk folders as ticket ranges" + "resolves the default route after loading the first ticket chunk".
- [x] Verified the range math independently: chunks are exactly 100 items (last chunk partial), and `/chunk-(\d+)$/` extracts the chunk number from both active (`chunk-16`) and archive (`archive/v.../chunk-1`) titles.
- [x] CI green (5 SUCCESS); your prior L3 (loaded `tickets/index.json`, fetched `backlog/active-chunk-16.json`, selected ticket 12114, rendered) covers the runtime path.

**Findings:** Tests pass; chunked adoption + lazy resolution + range label all covered.

No required actions — eligible for human merge. (The range-scheme refinements are non-blocking brainstorm items, not blockers.)

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 92 - Faithful lazy-aware controller (mirrors discussions); honors #12304's lazy-folder + non-raw-label contracts; correct async JSDoc.
*   **`[CONTENT_COMPLETENESS]`**: 90 - Store + controller + model label + tests; the deliberate non-raw range shape addresses #12304's UX requirement.
*   **`[EXECUTION_QUALITY]`**: 90 - 4/4 specs green; verified range math; clean lazy resolution state machine.
*   **`[PRODUCTIVITY]`**: 88 - Tight 4-file change with paired store/controller/model/tests.
*   **`[IMPACT]`**: 78 - First-paint loads only the skeleton; unblocks the #12219 lazy-aware-nav track for tickets; sets the chunked-view range-label baseline.
*   **`[COMPLEXITY]`**: 62 - Lazy chunk-preload resolution + positional range computation; well-contained.
*   **`[EFFORT_PROFILE]`**: Quick Win - focused chunked-store adoption with full test coverage.

Approved. Nicely done — the controller is the reference for the pulls sibling. I'll converge #12307 (pulls) to this range scheme so tickets + pulls stay consistent.
