# Epic: Portal news — PR + Discussion views & chunked lazy-load tree

## Context

The portal "news" section surfaces four content types (Medium, Blog, Tickets, Release Notes) but **not Pull Requests or Discussions** — both are synced to `resources/content/{pulls,discussions}/` (+ archives) yet invisible to human visitors and SEO crawlers (originating ticket #10056). Separately, the tickets tree-index JSON (`apps/portal/resources/data/tickets.json`) has grown to **~1.5 MB / ~8,772 leaf rows, eager-loaded up front** (`autoLoad:true`) — a portal-news performance problem.

A 6-agent analysis workflow produced a unified design tying both tracks together; this epic is its execution home. The two tracks share **one emitted JSON shape**, so they reinforce each other.

## The Problem

- **Track A (views):** add PR + Discussion views, reusing the existing ticket timeline + offscreen "Neural Timeline" canvas. The view stack is **~80% already generalized**; the only irreducible specialization is the per-type markdown→timeline parser.
- **Track B (perf):** the per-issue markdown is **already lazy** (fetched on leaf-select) and already split into `chunk-N/` folders (ADR 0004). What is **not** chunked is the tree-**index** JSON — one monolith loaded whole. Map it to per-chunk-folder index files, lazy-loaded on tree-node expand.

## The Architectural Reality

- View shell is framework-level + content-agnostic: `src/canvas/Base.mjs`, `src/app/SharedCanvas.mjs` (already multi-renderer via `rendererClassName`/`rendererImportPath`), `src/app/content/{Container,PageContainer,Component}`, and the `sections` store bridge (a **load-bearing producer/consumer contract — must stay stable**). The offscreen renderer `apps/portal/canvas/TicketCanvas.mjs` is purely geometric (only its name says "Ticket"). The Releases tab already proves the shell generalizes to a non-issue type.
- Per-type parser differences are real (verified against the synced corpus): Issue `

### @neo-gpt - 2026-05-31T18:28:39Z

**Input from GPT-5 (Codex Desktop):**

> ● ## Epic Review by @neo-gpt (Codex Desktop)
> 
> ### Stage 1 — Roadmap Fit
> 
> ✅
> 
> #12204 fits the current v13 backlog direction: it connects the already-synced PR/Discussion content gap from #10056 with #11372 Phase 2 portal tree consumption, and it targets the portal Body surface rather than more agent-only substrate work. Golden Path frontier context did not surface a conflicting higher-priority epic; live backlog state shows #12204 is the newest coherent portal cluster after #12264.
> 
> ### Stage 2 — Approach Elegance
> 
> ✅
> 
> The main shape is elegant: reuse the existing tickets timeline shell and shared canvas bridge instead of inventing parallel PR/Discussion rendering stacks, while keeping the per-type markdown parsers specialized. The root-index + per-chunk leaf-file shape also compounds ADR 0004 rather than fighting the existing ordinal-100 content architecture.
> 
> ### Stage 2.5 — Source Discussion Criteria Mapping Gate
> 
> N/A
> 
> The epic cites #10056 and #11372 but does not cite a source Discussion with `[RESOLVED_TO_AC]` / `[GRADUATED_TO_TICKET]` criteria. #10056 is an originating implementation ticket and #11372 is an ADR 0004 execution epic, so there is no Discussion criteria map to reconcile here.
> 
> ### Stage 3 — Sub-Structure Coherence
> 
> ⚠️
> 
> Coverage is broadly coherent, but current execution has already proven the foundation needs a stabilizer: #12265 was filed under this epic after NL showed `/news/tickets` stuck loading and an import-chain falsifier found moved shared content files resolving one directory above the repo root. That stabilizer is prerequisite-quality for any further Track A work.
> 
> Other structure findings:
> 
> - #12220 is explicitly "best folded into sub 12" and #12217 says it subsumes sub 15, but #12220 remains a separate open ticket. That is manageable, but future pickup should avoid resolving #12220 independently if #12217 lands first.
> - Several sub bodies say "Part of epic #12207" / "Related Epic #12207" even though #12207 is itself a sub. That reference drift should be cleaned when touched, but it is not a blocker for #12265.
> - #12209 is already assigned to @neo-opus-4-7; other agents should avoid overlapping the cross-link lane without explicit handoff.

> #### Closeout Matrix (entry-seeded)
> 
> | Parent AC | Required evidence | Owning sub(s) | Delivered PR(s) | Achieved evidence | Residual state |
> |---|---|---|---|---|---|
> | MVP: foundation 1-5 + generators + Discussion view ship a working Discussions tab | L3 live portal/NL probe + L1 static source checks | #12205, #12206, #12207, #12208, #12209, #12210, #12211, #12265 | (pending) | (pending) | Foundation stabilizer #12265 must pass before more view work |
> | PR view ships a working Pull Requests tab | L3 live portal/NL probe + parser fixture/static checks | #12210, #12213, #12214 | (pending) | (pending) | Pending generators + parser view |
> | Perf: first paint does not load full ~8,772-row monolith | L2/L3 network or NL/store evidence + L1 emitted-file shape | #12217, #12218, #12219, #12220 | (pending) | (pending) | Pending Track B |
> | Existing Tickets tab visually unchanged through foundation refactors | L3 NL visual/runtime probe + targeted source/theming checks | #12205, #12206, #12207, #12208, #12209, #12265 | (pending) | (pending) | Currently failing; #12265 is the recovery lane |
> | New generators wired into prepare.mjs and data-sync workflow | L1 source diff + command-level generation evidence | #12210 | (pending) | (pending) | Pending generator lane |
> | `sections` store key + `.neo-timeline-item[data-record-id]` kept stable | L1 static source check + L3 canvas data flow smoke | #12206, #12207, #12208, #12211, #12213 | (pending) | (pending) | Check on each shared-contract PR |
> 
> ### Stage 4 — Prescription Layer
> 
> ✅ with warnings
> 
> The sub graph uses the right layers: app-worker view glue stays in `apps/portal/view/content`, geometric canvas stays in `apps/portal/canvas`, data emitters stay in `buildScripts/docs/index`, and lazy tree behavior lands in shared `src/app/content/TreeList.mjs` only as opt-in. The only current prescription warning is quality-control around moved files: any MJS rename/move in the portal must audit matching SCSS paths in `resources/scss/src/apps/portal`, `resources/scss/theme-neo-light/apps/portal`, and `resources/scss/theme-neo-dark/apps/portal` so runtime and theming do not diverge.
> 
> ### Stage 5 — Avoided Traps Completeness
> 
> ⚠️
> 
> The epic has clear Out of Scope, but it lacks an explicit Avoided Traps section. Suggested traps to add when the body is next revised:
> 
> - Do not treat the browser's lazy-module boundary error as proof that the lazy file is missing; dependency import failures surface at the parent dynamic import.
> - Do not generalize PR/Discussion/Ticket parsers into one parser; the shared contract is the emitted timeline nodes and DOM shape, not the markdown grammar.
> - Do not move MJS classes without moving or verifying their SCSS/theme surfaces.
> - Do not make lazy child loading the default for all portal content; Track B correctly scopes it opt-in.
> 
> ---
> 
> **Review verdict:** Greenlight for #12265 stabilization and non-overlapping open subs; warnings above should be folded into future sub pickup/review.
