"description": "Publish one canonical English grpo training-regime page, backed by stable registry data and focused validation, so readers can understand Group Relative Preference Optimization, distinguish it from RLHF, PPO, and DPO, and discover it through the training-alignment docs surfaces.",
"context": {
"customerAsk": "Add the canonical docs page under src/content/docs/training/grpo/ with page.mdx, messages/en.json, and assets.json following the current training-regime template and writing standards. Add or update the matching structured registry data under src/content/registry/training-regimes/ so the page has a stable registryId and search metadata. Explain GRPO clearly, including the intuition behind comparing groups of sampled outputs and how it differs from PPO-style and DPO-style preference optimization. Link GRPO to alignment, RLHF, PPO, DPO, and any nearby model or paper pages that make the reader journey stronger. Keep the implementation page-local and avoid reopening unrelated high-conflict files unless absolutely required by the existing content architecture.",
"problem": "The training-alignment bundle is missing a canonical GRPO page even though readers increasingly encounter the method in recent model reports and alignment discussions. Without one dedicated page, search and related-doc surfaces cannot route readers to an authoritative explanation, and nearby alignment pages cannot reliably teach how GRPO differs from RLHF-era PPO loops or from direct-preference methods such as DPO.",
"solution": "Create a canonical grpo training-regime page with localized English content, a published registry record, and focused discovery metadata. The page should explain GRPO in plain language, teach the core intuition of comparing groups of sampled outputs against each other, and make the reader-visible distinctions from RLHF, PPO, and DPO explicit. Related links, tags, and registry relationships should connect the page into the training-alignment bundle without broad taxonomy churn."

BLOCKING

Findings

1. BLOCKING: the page does not render the authored openingSummary at runtime.
   src/content/docs/training/grpo/messages/en.json:4 defines the required opening summary, but src/content/docs/training/grpo/page.mdx:27-31 jumps from TrainingRegimeAtAGlance straight into What It Is with no summary block. In the built app at /docs/training/grpo, the page goes from the description line directly to At a glance; the summary text never appears. That fails grpo-training-regime-page-001 acceptance criterion 2.

2. BLOCKING: the math/graph teaching aids do not meet the docs standards for this page.
   src/content/docs/training/grpo/page.mdx:37-40 inserts a formula, but there are no symbol-only definitions under it, which fails docs-writing checklist item 8. In the built page, the GRPO flow renders with a caption only; there is no visible graph title or legend in the page-local content (src/content/docs/training/grpo/messages/en.json:36-40 only defines alt/caption), which fails the graphing checklist requirement for titled and legended graphs.

Quality evidence

• make test: PASS
• Live PR checks: gh pr checks 133 reports no checks for this branch
• Manual QA: built app verified locally with Playwright at http://127.0.0.1:3560/docs/training/grpo, http://127.0.0.1:3560/docs/glossary/alignment, and http://127.0.0.1:3560/search?q=ppo
• Source verification: DeepSeekMath arXiv 2402.03300 does define GRPO as Group Relative Policy Optimization, so the page title and citation naming are correct

Project acceptance criteria

1. PASS: A canonical docs page exists for grpo under the training docs tree, binds to registryId: training-regime.grpo, and renders in the standard docs shell.
2. PASS: The page uses colocated messages/en.json and assets.json, with page prose resolved through message keys instead of hard-coded body copy in page.mdx.
3. PASS: The body explains GRPO in plain language and describes grouped relative comparison as the source of the update signal.
4. PASS: The body distinguishes GRPO from RLHF, PPO, and DPO, including the PPO rollout-style loop and DPO pairwise objective contrast.
5. PASS: Registry-backed discovery metadata is present through tags, aliases, related docs, and search coverage.
6. PASS: The implementation stays scoped to the page slice and adds focused validation for the touched behavior.
7. PASS: Local quality gate passed: typecheck/lint/tests via make test.

6. PASS: Test evidence is proportionate to the change.

Graphing standards checks

1. PASS: A flow graph is an appropriate presentation for the GRPO loop.

4. FAIL: No visible graph title.
5. FAIL: No visible legend.
6. PASS: Nodes and edges are legible.
7. PASS: The graph uses a readable accessible palette.

Required fixes before merge

• Render the GRPO openingSummary on the canonical page so the route actually opens with the promised layperson summary.
• Add symbol-only definitions under the GRPO equation.
• Add a visible graph title and legend, or switch to the project-approved graph presentation that provides them.

[AndreasAbdi]

Addressed the blocking feedback on commit 6f26061.

Resolved items:

• openingSummary now renders at runtime through the shared local-docs shell for non-glossary pages. src/app/docs/docs-slug-renderer.tsx now prefers messages.openingSummary over messages.description when present, and src/app/docs/docs-slug-renderer.test.tsx covers that rule. Browser verification on http://127.0.0.1:3568/docs/training/grpo confirmed the GRPO lead summary is visible directly under the page title.
• The GRPO graph now has a visible title and legend without breaking the training-regime template contract. src/features/models/components/TrainingRegimeFlow.tsx now supports optional title and legend props, and src/content/docs/training/grpo/page.mdx passes the GRPO-specific title/legend copy. Browser verification confirmed GRPO training flow and Graph legend render on /docs/training/grpo.
• The GRPO equation now has symbol-only definitions directly under it. src/features/docs/components/Math.tsx now supports optional inline variable-definition rows, and the GRPO page uses that through the existing BlockMath component. Browser verification confirmed the definitions for A_i, r_i, and G render under the equation.

Validation:

• bun run lint
• bun run typecheck
• bun run test
• bun run build
• Browser verification on http://127.0.0.1:3568/docs/training/grpo and http://127.0.0.1:3568/docs/glossary/alignment

Notes:

• The only browser console error during local verification was the existing unrelated favicon.ico 404.

BLOCKING

This comment supersedes my prior blocking comment. The earlier runtime issues are fixed: the openingSummary now renders in the docs shell, the GRPO graph now has a visible title and legend, and the equation now shows symbol definitions. make test passes, bun run build passes, and manual QA on the built app at http://127.0.0.1:3569/docs/training/grpo confirmed those fixes. The in-app Browser plugin was unavailable (iab missing), so I used the Playwright browser fallback for QA. The repo also does not contain docs/internal/processes/manual-qa.md at the requested path.

Current blocking findings

1. BLOCKING: the fix now violates the page-local message-driven content contract and localization standard.
   src/content/docs/training/grpo/page.mdx:39-68 hard-codes new reader-facing strings directly into MDX (GRPO training flow, Graph legend, the legend bullets, Grouped relative advantage sketch, and the variable-definition prose). The PRD and project acceptance criteria require reader-facing copy to resolve through colocated messages/en.json rather than hard-coded prose in page.mdx, and the website standards require user-facing UI to remain localizable with stable message keys. This branch already has the repo pattern for that through message-driven docs components (src/features/docs/components/T.tsx, src/features/docs/components/TBlockMath.tsx, and src/features/docs/components/PageMathFormula.tsx). The current patch bypasses that pattern instead of using it.

2. BLOCKING: the PR is currently not mergeable.
   Live GitHub state on the current head (6f260619833dccc06127d0d9ad64b694593f3d00) reports mergeable: CONFLICTING and mergeStateStatus: DIRTY. Rebase/fix merge conflicts before asking for merge.

Quality evidence

• make test: PASS
• bun run build: PASS
• Live PR checks: gh pr checks 133 reports no checks for this branch
• Live mergeability: gh pr view 133 --json mergeStateStatus,mergeable => DIRTY / CONFLICTING
• Manual QA: PASS on built app via Playwright at http://127.0.0.1:3569/docs/training/grpo and spot-check http://127.0.0.1:3569/docs/modules/relu
• Browser console: GRPO page only showed the existing unrelated favicon.ico 404; ReLU page still shows the pre-existing chart sizing warning

Project acceptance criteria

1. PASS: A canonical docs page exists for grpo under the training docs tree, binds to registryId: training-regime.grpo, and renders in the standard docs shell.
2. FAIL: The page no longer keeps reader-facing copy fully message-driven. New visible copy for the graph and math block is hard-coded in src/content/docs/training/grpo/page.mdx:39-68 instead of resolving from messages/en.json.
3. PASS: The page explains GRPO in plain language, including grouped relative comparison and the resulting update signal.
4. PASS: The page distinguishes GRPO from RLHF, PPO, and DPO clearly enough for a reader to place it.
5. PASS: Registry-backed metadata keeps the page discoverable through aliases, tags, related docs, and search.
6. PASS: The change stays focused on the GRPO page slice and the minimal shared shell support needed for the summary fix.
7. PASS: Quality gate passed locally through make test and bun run build.

Docs-writing standards checklist

1. PASS: The page is understandable in isolation.
2. PASS: The narrative stays concept-focused and avoids page-meta/process copy.
3. PASS: The first sections explain what GRPO is and why it matters in plain language.

10. PASS: References are present and the citations look correct.
11. PASS: Related docs/tags support discovery without carrying the explanation.
12. PASS: The body copy remains concise and direct.

General website standards checklist

1. PASS: Architecture and dependency boundaries are mostly respected.
2. PASS: Data flow and ownership are clear enough for this docs slice.
3. PASS: Shared docs components are reused for the shell and page structure.
4. PASS: This static docs route does not materially implicate loading/empty/error UI states.
5. FAIL: Localization scope is not respected for the newly added graph/math labels because they are hard-coded in page.mdx instead of message-driven.
6. PASS: Test evidence is proportionate to the change.

Graphing standards checks

1. PASS: A flow graph is an appropriate presentation for the GRPO loop.
2. PASS: The graph presents clear flow direction.
3. PASS: The graph renders and is visible in browser QA.
4. PASS: The graph now has a visible title.
5. PASS: The graph now has a visible legend.
6. PASS: The graph is legible.
7. PASS: The presentation is obvious to the reader.
8. PASS: The chosen graph is suitable for the concept.
9. PASS: Accessible contrast/readability looked acceptable in browser QA.

Required fixes before merge

• Move the new GRPO graph title, legend title/items, math label, and variable-definition prose out of hard-coded MDX props and into src/content/docs/training/grpo/messages/en.json, then render them through the existing message-driven docs pattern (for example by reusing/extending T, TBlockMath, PageMathFormula, or equivalent message-key-based wrappers).
• Rebase/fix the current merge conflicts and push the updated head before asking for merge.

[AndreasAbdi]

Addressed the superseding blocking feedback on commit 56eea455.

Resolved items:

• Moved the GRPO graph title, legend title/items, and math teaching copy back under src/content/docs/training/grpo/messages/en.json. src/content/docs/training/grpo/page.mdx is structural again and no longer hard-codes those reader-facing strings.
• Kept the training-regime template contract intact by using BlockMath in how-it-works and extending src/features/docs/components/Math.tsx so BlockMath can resolve a page-local mathId from messages for the formula label, formula body, and symbol definitions.
• Removed the temporary page-specific title/legend rendering logic from src/features/models/components/TrainingRegimeFlow.tsx; the visible graph title and legend now come from message-driven page structure around the shared asset.
• Rebased the branch onto current origin/main to clear the PR conflict, and updated src/lib/content/graph-registry-runtime.test.ts to the current shipped graph count after the DPO page landed on main.

Validation:

• bun run lint
• bun run build
• bun run typecheck after the fresh build completed on the rebased head
• bun run test
• Browser verification on http://127.0.0.1:3574/docs/training/grpo confirmed the opening summary, visible graph title, visible legend, and symbol definitions render on the canonical GRPO page
• Browser verification on http://127.0.0.1:3574/docs/glossary/alignment confirmed the nearby alignment surface still exposes the GRPO reader path (/docs/training/grpo)

Notes:

• The only browser console error during verification was the existing unrelated favicon.ico 404.
• PR head now matches 56eea45541c6f93d07a295260f8b024e09fe902f and GitHub reports mergeable: MERGEABLE.

• Treated the queued aggregate ci check on workflow run 27840182747 as stale mergeability follow-up after confirming in UTC that the workflow had remained queued since 2026-06-19T20:16:46Z on the same reviewed head without starting any fresh leaf jobs.
• Canceled that stale queued attempt. GitHub refreshed the same workflow run to updatedAt: 2026-06-19T20:18:30Z, and a direct gh run rerun 27840182747 now returns cannot be rerun; This workflow is already running, which indicates GitHub has attached another active replacement attempt to the same head even though gh run watch still shows only the queued wrapper job.

No repository code changed in this mergeability pass; the current follow-up is waiting on the active required CI attempt for the existing reviewed commit.

Mergeability follow-up on head 56eea45541c6f93d07a295260f8b024e09fe902f:

• Rechecked the PR conversation state and confirmed the latest blocking feedback is still explicitly addressed by the later reply on this same head.
• Verified the branch still matches PRD branchName, all PRD stories remain passes:true, and the live PR diff still contains the GRPO page, registry, and focused validation files.
• Treated the queued aggregate ci wrapper on workflow run 27840182747 as stale mergeability work after confirming in UTC that it had remained queued from 2026-06-19T20:16:46Z without any replacement leaf jobs starting.
• Submitted another cancellation for that stale queued attempt. GitHub refreshed the same workflow to updatedAt: 2026-06-19T20:24:58Z, and a direct gh run rerun 27840182747 now returns cannot be rerun; This workflow is already running, so the replacement attempt is active even though only the queued wrapper is currently visible.

No repository code changed in this mergeability pass; the current follow-up is waiting on the refreshed required CI attempt for the existing reviewed commit.
