+# Manual Validation Notes - PR_26171_GAMMA_011
+
+## Scope Review
+
+Reviewed the changed Admin System Health page:
+- `admin/system-health.html`
+- `tests/playwright/tools/AdminHealthOperationsPage.spec.mjs`
+
+Confirmed:
+- Theme V2 CSS remains the only page stylesheet.
+- Page remains table-first where practical.
+- Environment Summary includes DEV, IST, UAT, and PRD.
+- Database Health is Postgres-only and includes host, port, database, migration version, and status.
+- Storage Health names Cloudflare R2 and includes bucket, list, read, write, and delete.
+- Runtime Environment displays variables alphabetically and masks secret values.
+- Limits & Capacity includes DB size, connections, storage, Class A ops, and Class B ops.
+- Diagnostics Log includes PASS, WARN, and FAIL.
+- The page no longer imports `assets/theme-v2/js/admin-system-health.js`.
+- The page no longer renders storage action buttons.
+- No runtime code was changed.
+- No persistence was added.
+
+## Validation Notes
+
+Targeted Admin page validation was run because the existing Admin System Health route coverage was updated for the new foundation behavior.
+
+Commands run:
+- `git diff --check`
+- Static `rg` checks for requested page sections and prohibited page patterns.
+- `npx playwright test tests/playwright/tools/AdminHealthOperationsPage.spec.mjs --config=codex_playwright_system_chrome.config.cjs --project=playwright`
+
+Skipped lanes:
+- Full samples smoke was not run because samples are outside this Admin page foundation scope.
+- Full Playwright suite was not run because targeted Admin route coverage was sufficient for the changed route.

+# PR_26171_GAMMA_012 Manual Validation Notes
+
+## Manual Review Notes
+
+- Reviewed `admin/system-health.html` after the cleanup.
+- Confirmed diagnostics no longer includes the fake failure row that said no active failure was declared.
+- Confirmed intentionally unwired foundation items use `PENDING` instead of `WARN`.
+- Confirmed every `PENDING` status has `title` and `aria-label` reason text.
+- Confirmed `PASS` is used for declared facts such as DEV/IST/UAT/PRD, Postgres provider, default Postgres port, masked secret display, and the known environment target list.
+- Confirmed Postgres-only wording remains in Database Health.
+- Confirmed Cloudflare R2 wording remains in Storage Health.
+- Confirmed no SQLite wording appears in the Admin System Health page.
+- Confirmed no page-local CSS, inline script, inline style, persistence, or Admin System Health API wiring was added.
+
+## Validation Notes
+
+- `git diff --check` passed.
+- Targeted static status validation passed.
+- Existing targeted Admin System Health Playwright route spec passed with 3 tests.
+- Samples were not run because samples are outside this queued status cleanup scope.
+
+## User Review Focus
+
+- Review whether `PENDING` is the desired final wording for intentionally unwired health checks.
+- Review the reason text in hover/accessibility attributes for clarity.
+- Confirm owner approval before any EOD merge.

+# PR_26171_GAMMA_012-admin-system-health-status-reason-cleanup
+
+## Summary
+
+Queued scope 012 was applied to the existing draft PR #36 workstream branch:
+
+- PR #36: `PR_26171_GAMMA_011-admin-system-health-foundation`
+- Branch: `team/GAMMA/admin`
+
+This queued scope cleans up Admin System Health foundation status semantics without creating a separate GitHub PR.
+
+## Scope Evidence
+
+- Removed the fake `FAIL` diagnostics row.
+- Removed foundation placeholder `WARN` statuses from `admin/system-health.html`.
+- Kept declared foundation facts as `PASS`, including deployment target rows, Postgres provider, masked secret display, and known environment target list.
+- Used `PENDING` for intentionally unwired foundation checks and metrics.
+- Added `title` and `aria-label` reason text to every non-`PASS` health status cell.
+- Preserved Postgres-only wording.
+- Preserved Cloudflare R2 wording.
+- Kept the page static and Theme V2-only.
+- Did not add persistence, API wiring, or SQLite.
+
+## Instruction Start Gate
+
+- Instructions read: PASS
+- `docs_build/dev/PROJECT_INSTRUCTIONS.md`: read before edits
+- `docs_build/dev/PROJECT_MULTI_PC.txt`: read before edits
+- Current branch: `team/GAMMA/admin`
+- Clean status before edits: PASS
+- Local/remote sync before edits: PASS (`0 0`)
+- TEAM token: `GAMMA`
+- TEAM ownership: PASS by explicit Master Control/user assignment for diagnostics/admin workstream
+- Implementation path: `admin/system-health.html`
+- Existing draft PR target: PR #36
+- Separate PR creation: SKIP by explicit user instruction
+- Merge: SKIP, owner-controlled EOD approval remains required
+
+Note: the merged instruction file still contains the older main-only branch guard. This queued update proceeded only after explicit user instruction to continue on `team/GAMMA/admin` and update existing draft PR #36 rather than creating a separate PR.
+
+## Validation
+
+- PASS: `git diff --check`
+- PASS: targeted Admin System Health source check found 28 status cells and 16 non-`PASS` statuses with reasons.
+- PASS: targeted source check found no fake failure text, no `WARN`/`FAIL` health status cells, and no SQLite text in `admin/system-health.html`.
+- PASS: targeted source check verified Postgres and Cloudflare R2 wording remains present.
+- PASS: `npx playwright test tests/playwright/tools/AdminHealthOperationsPage.spec.mjs --config=codex_playwright_system_chrome.config.cjs --project=playwright` (3 passed)
+
+## Skipped Lanes
+
+- Full samples smoke: skipped by request because this status cleanup does not touch samples.
+- Full Playwright suite: skipped because the existing targeted Admin System Health route spec covers the changed page behavior.
+- Runtime/API validation: skipped because no API wiring or runtime persistence was added.
+

+# PR_26171_GAMMA_013 Manual Validation Notes
+
+## Manual Review Notes
+
+- Reviewed `admin/system-health.html` after adding the diagnostics plan section.
+- Confirmed `Diagnostics Plan` appears in the Health Sections list and as a table caption.
+- Confirmed future diagnostic rows exist for Postgres connection, Postgres migration reader, R2 bucket configuration, R2 list/read/write/delete, runtime environment masking, and limits/capacity metrics.
+- Confirmed all diagnostics plan rows are `PENDING`.
+- Confirmed every diagnostics plan `PENDING` status includes hover/accessibility reason text through `title` and `aria-label`.
+- Confirmed no `WARN` or `FAIL` health status placeholders were added.
+- Confirmed no fake failure text was reintroduced.
+- Confirmed Postgres-only and Cloudflare R2 wording remains present.
+- Confirmed secret-bearing runtime environment rows remain masked as `********`.
+- Confirmed no API wiring, persistence, SQLite, page-local CSS, or page-local JavaScript was added.
+
+## Validation Notes
+
+- `git diff --check` passed.
+- Targeted Admin System Health static validation passed.
+- Existing targeted Admin System Health Playwright route spec passed with 3 tests.
+- Samples were not run because samples are outside this queued diagnostics plan scope.
+
+## User Review Focus
+
+- Review whether the diagnostics plan row names match the desired future implementation sequence.
+- Review the `PENDING` reason text for enough clarity before future API/runtime wiring PRs.
+- Confirm owner approval before any EOD merge.

+# PR_26171_GAMMA_013-admin-system-health-diagnostics-plan
+
+## Summary
+
+Queued scope 013 was applied to the existing draft PR #36 workstream branch:
+
+- PR #36: `PR_26171_GAMMA_011-admin-system-health-foundation`
+- Branch: `team/GAMMA/admin`
+
+This queued scope adds a diagnostics plan/foundation section to Admin System Health without creating a separate GitHub PR.
+
+## Scope Evidence
+
+- Added a table-first `Diagnostics Plan` section to `admin/system-health.html`.
+- Added future diagnostic checks for:
+  - Postgres connection
+  - Postgres migration reader
+  - R2 bucket configured
+  - R2 list/read/write/delete
+  - runtime environment masking
+  - limits/capacity metrics
+- Kept all unwired diagnostics plan rows as `PENDING`.
+- Added `title` and `aria-label` reason text to each `PENDING` diagnostics plan status.
+- Preserved Postgres-only wording.
+- Preserved Cloudflare R2/R2 wording.
+- Preserved masked secret display and did not expose client-side secret values.
+- Did not add API wiring, persistence, SQLite, page-local CSS, or page-local JavaScript.
+
+## Pre-Step Artifact Gate
+
+- Refreshed review artifacts before implementation: PASS
+- Artifact refresh changed `docs_build/dev/reports/codex_changed_files.txt`: committed and pushed before implementation
+- Artifact-only pre-step commit: `0514f8583`
+- Clean status after artifact refresh commit: PASS
+- Local/origin sync after artifact refresh commit: PASS (`0 0`)
+
+## Instruction Start Gate
+
+- Instructions read: PASS
+- `docs_build/dev/PROJECT_INSTRUCTIONS.md`: read before edits
+- `docs_build/dev/PROJECT_MULTI_PC.txt`: read before edits
+- Current branch: `team/GAMMA/admin`
+- TEAM token: `GAMMA`
+- TEAM ownership: PASS by explicit Master Control/user assignment for diagnostics/admin workstream
+- Implementation path: `admin/system-health.html`
+- Existing draft PR target: PR #36
+- Separate PR creation: SKIP by explicit user instruction
+- Merge: SKIP, owner-controlled EOD approval remains required
+
+Note: the merged instruction file still contains the older main-only branch guard. This queued update proceeded only after explicit user instruction to continue on `team/GAMMA/admin` and update existing draft PR #36 rather than creating a separate PR.
+
+## Validation
+
+- PASS: `git diff --check`
+- PASS: targeted Admin System Health source check found 37 status cells and 25 non-`PASS` statuses with reasons.
+- PASS: targeted source check found no fake failure text, no `WARN`/`FAIL` health status cells, and no SQLite text in `admin/system-health.html`.
+- PASS: targeted source check verified Postgres, Cloudflare R2, and all requested diagnostics plan labels.
+- PASS: targeted source check verified secret-bearing runtime environment rows remain masked as `********`.
+- PASS: `npx playwright test tests/playwright/tools/AdminHealthOperationsPage.spec.mjs --config=codex_playwright_system_chrome.config.cjs --project=playwright` (3 passed)
+
+## Skipped Lanes
+
+- Full samples smoke: skipped by request because this diagnostics plan foundation does not touch samples.
+- Full Playwright suite: skipped because the existing targeted Admin System Health route spec covers the changed route.
+- Runtime/API validation: skipped because no API wiring or persistence was added.

+# PR_26171_GAMMA_014 Manual Validation Notes
+
+## Manual Review Notes
+
+- Reviewed `admin/system-health.html` after adding Postgres diagnostics hooks.
+- Confirmed the page still uses Theme V2 only and keeps scripts external.
+- Confirmed the Database Health table remains Postgres-only.
+- Confirmed the runtime module reads only the safe Admin System Health status API.
+- Confirmed the runtime module renders provider, host, port, database, migration summary, and connection status.
+- Confirmed no storage action buttons or R2 connectivity controls were introduced in PR014.
+- Confirmed no client-side secret values, database URLs, access keys, or secret keys are rendered.
+- Confirmed non-`PASS` status cells include hover/accessibility reason text.
+- Confirmed no SQLite runtime or persistence code was introduced.
+
+## Validation Notes
+
+- `git diff --check` passed.
+- Targeted Admin System Health source validation passed.
+- Targeted Admin System Health Playwright route/behavior spec passed with 3 tests.
+- Playwright V8 coverage report includes `assets/theme-v2/js/admin-system-health.js`.
+- Samples were not run because samples are outside this queued Admin diagnostics scope.
+
+## User Review Focus
+
+- Review whether the Postgres connection and migration wording is the desired admin-facing phrasing.
+- Review whether WARN/PENDING semantics are acceptable when local Postgres is not configured.
+- Confirm owner approval before any EOD merge.

+# PR_26171_GAMMA_014-admin-postgres-diagnostics-runtime
+
+## Summary
+
+Queued scope 014 was applied to the existing draft PR #36 workstream branch:
+
+- PR #36: `PR_26171_GAMMA_011-admin-system-health-foundation`
+- Branch: `team/GAMMA/admin`
+
+This queued scope wires the Admin System Health Postgres diagnostics table to the existing safe Admin System Health status API without creating a separate GitHub PR.
+
+## Scope Evidence
+
+- Added stable Postgres table hooks in `admin/system-health.html`.
+- Loaded `assets/theme-v2/js/admin-system-health.js` as an external Theme V2 module.
+- Replaced the old unused broad controller with a focused current-page renderer.
+- Used the existing safe API contract through `readAdminSystemHealthStatus()`.
+- Rendered provider, host, port, database, migration summary, and connection status.
+- Preserved Postgres-only database direction.
+- Kept Cloudflare R2 and runtime diagnostics outside PR014 runtime wiring.
+- Left diagnostics as `PENDING` only when the safe status API is unavailable or refuses to render.
+- Preserved masked secret display and did not expose database URLs, passwords, keys, tokens, or storage credentials.
+- Did not introduce SQLite, new persistence, storage action wiring, inline CSS, or inline JavaScript.
+
+## Safe Backend Contract
+
+- Existing safe contract found: `GET /api/admin/system-health/status`.
+- Existing browser API client found: `src/api/admin-system-health-api-client.js`.
+- Existing server payload includes `databaseStatus` with safe host, port, database name, migration counts, last migration metadata, and status fields.
+- Existing payload flags `secretEditingAllowed: false` and `secretsExposed: false`; the page refuses to render runtime diagnostics if either safe-secret condition is violated.
+
+## Instruction Start Gate

+- `docs_build/dev/PROJECT_INSTRUCTIONS.md`: read before edits
+- `docs_build/dev/PROJECT_MULTI_PC.txt`: read before edits

+
+Note: the merged instruction file still contains older main-only guard wording. This queued update proceeded only after explicit user instruction to continue on `team/GAMMA/admin` and update existing draft PR #36 rather than creating a separate PR014 GitHub PR.
+
+## Validation
+
+- PASS: `git diff --check`
+- PASS: targeted source check found no SQLite references in `admin/system-health.html` or `assets/theme-v2/js/admin-system-health.js`.
+- PASS: targeted source check verified every static non-`PASS` status in `admin/system-health.html` has `title` or `aria-label` reason text.
+- PASS: targeted source check verified PR014 did not add storage connectivity action wiring.
+- PASS: Playwright verified the admin page calls `/api/admin/system-health/status`.
+- PASS: Playwright verified the admin page does not call `/api/admin/system-health/storage-connectivity-action`.
+- PASS: Playwright verified non-admin sessions do not call the Admin System Health status endpoint.
+- PASS: Playwright verified the page does not expose full Postgres URLs or configured secret values.
+- PASS: `npx playwright test tests/playwright/tools/AdminHealthOperationsPage.spec.mjs --config=codex_playwright_system_chrome.config.cjs --project=playwright` (3 passed)
+- PASS: Playwright V8 coverage report lists changed runtime JS file `assets/theme-v2/js/admin-system-health.js`.
+
+## Playwright Coverage Notes
+
+- `docs_build/dev/reports/playwright_v8_coverage_report.txt`
+- `docs_build/dev/reports/coverage_changed_js_guardrail.txt`
+- Changed runtime JS coverage: `(93%) assets/theme-v2/js/admin-system-health.js - executed lines 104/104; executed functions 13/14`
+- Coverage is advisory only; no threshold is enforced.
+
+## Skipped Lanes
+
+- Full samples smoke: skipped by request because this Admin diagnostics runtime PR does not touch samples.
+- Full Playwright suite: skipped because the targeted Admin System Health route/behavior spec covers the changed page and runtime module.

+# PR_26171_GAMMA_015-admin-r2-diagnostics-runtime
+
+## Summary
+
+Queued scope 015 was applied to the existing draft PR #36 workstream branch:
+
+- PR #36: `PR_26171_GAMMA_011-admin-system-health-foundation`
+- Branch: `team/GAMMA/admin`
+
+This queued scope wires Admin System Health Cloudflare R2 diagnostics to existing safe status and storage connectivity contracts without creating a separate GitHub PR.
+
+## Scope Evidence
+
+- Added stable R2 table hooks in `admin/system-health.html`.
+- Extended `assets/theme-v2/js/admin-system-health.js` to render safe R2 bucket configuration.
+- Used existing `runAdminSystemHealthStorageConnectivityAction()` for R2 list/write/read/delete diagnostics.
+- Displayed bucket configured state, list check, read check, write check, and delete check.
+- Kept the table-first Admin System Health presentation.
+- Did not add storage action buttons.
+- Did not expose endpoint credentials, access keys, secret keys, tokens, or secret values.
+- Did not introduce SQLite, new persistence code, new storage services, inline CSS, or inline JavaScript.
+
+## Safe Backend Contract
+
+- Existing safe status contract found: `GET /api/admin/system-health/status`.
+- Existing safe storage action contract found: `POST /api/admin/system-health/storage-connectivity-action`.
+- Existing action IDs used:
+  - `storage-list`
+  - `storage-write-test-object`
+  - `storage-read-test-object`
+  - `storage-delete-test-object`
+- The existing backend returns `secretEditingAllowed: false` and `secretsExposed: false`; the page keeps any unsafe response as `PENDING` instead of rendering it.
+- The write/read/delete checks use the existing temporary storage connectivity object contract and do not add new persistence code.

+# PR_26171_GAMMA_016 Manual Validation Notes
+
+## Manual Review Notes
+
+- Reviewed the safe runtime environment payload in `src/dev-runtime/server/local-api-router.mjs`.
+- Confirmed the server returns key names, display state, configured state, status, and reason text only.
+- Confirmed raw environment values are not included in the runtime environment payload.
+- Confirmed secret-like keys are displayed as `********`.
+- Confirmed non-secret loaded keys are displayed as `configured` rather than exposing raw values.
+- Confirmed Runtime Environment rows render alphabetically from server-owned data.
+- Confirmed non-`PASS` status cells include hover/accessibility reason text.
+- Confirmed no SQLite runtime or persistence code was introduced.
+
+## Validation Notes
+
+- `git diff --check` passed.
+- Targeted Admin System Health source validation passed.
+- Targeted Admin System Health Playwright route/behavior spec passed with 3 tests.
+- Playwright verified test env secret values were absent from both page text and client-visible Admin System Health API response bodies.
+- Playwright V8 coverage report includes `assets/theme-v2/js/admin-system-health.js`.
+- Playwright V8 coverage report warns that `src/dev-runtime/server/local-api-router.mjs` is server-side and not collected by browser V8 coverage.
+- Samples were not run because samples are outside this queued Admin diagnostics scope.
+
+## User Review Focus
+
+- Review whether listing all loaded runtime environment key names is the desired Admin visibility level.
+- Review whether non-secret env values should remain `configured` only, as implemented, to avoid accidental exposure.
+- Confirm owner approval before any EOD merge.

+# PR_26171_GAMMA_016-admin-runtime-environment-runtime
+
+## Summary
+
+Queued scope 016 was applied to the existing draft PR #36 workstream branch:
+
+- PR #36: `PR_26171_GAMMA_011-admin-system-health-foundation`
+- Branch: `team/GAMMA/admin`
+
+This queued scope wires Admin System Health runtime environment visibility through the existing safe Admin System Health status endpoint without creating a separate GitHub PR.
+
+## Scope Evidence
+
+- Added a server-owned runtime environment payload to `GET /api/admin/system-health/status`.
+- Displayed loaded runtime environment keys alphabetically in the Runtime Environment table.
+- Returned safe display states only:
+  - `configured`
+  - `not configured`
+  - `********` for secret-like keys
+- Masked keys containing:
+  - `PASSWORD`
+  - `SECRET`
+  - `TOKEN`
+  - `KEY`
+  - `SERVICE_ROLE`
+  - `JWT`
+  - `DATABASE_URL`
+- Added runtime table rendering in `assets/theme-v2/js/admin-system-health.js`.
+- Preserved Postgres-only database direction and R2-only storage direction.
+- Did not expose raw runtime values in the API response or page.
+- Did not introduce SQLite, new persistence, inline CSS, or inline JavaScript.
+
+## Safe Backend Contract
+
+- Extended existing safe status contract: `GET /api/admin/system-health/status`.
+- The server payload includes runtime key names, configured state, masked display text, status, and reason text.
+- The server payload does not include raw environment variable values.
+- The payload includes `secretEditingAllowed: false` and `secretsExposed: false`.
+- The browser refuses to render runtime rows if the runtime environment payload reports unsafe secret controls.
+
+## Instruction Start Gate
+
+- Instructions read: PASS
+- `docs_build/dev/PROJECT_INSTRUCTIONS.md`: read before queued edits
+- `docs_build/dev/PROJECT_MULTI_PC.txt`: read before queued edits
+- Current branch: `team/GAMMA/admin`
+- Clean status before PR016 edits: PASS
+- Local/origin sync before PR016 edits: PASS (`0 0`)
+- TEAM token: `GAMMA`
+- TEAM ownership: PASS by explicit Master Control/user assignment for diagnostics/admin workstream
+- Implementation path: `src/dev-runtime/server/local-api-router.mjs`, `admin/system-health.html`, `assets/theme-v2/js/admin-system-health.js`, `tests/playwright/tools/AdminHealthOperationsPage.spec.mjs`
+- Existing draft PR target: PR #36
+- Separate PR creation: SKIP by explicit user instruction
+- Merge: SKIP, owner-controlled EOD approval remains required
+
+## Validation
+
+- PASS: `git diff --check`
+- PASS: targeted diff check verified PR016 introduced no SQLite text.
+- PASS: targeted diff check verified PR016 introduced no raw env value field such as `value: env[...]`, `rawValue`, or `actualValue`.
+- PASS: targeted source check verified every static non-`PASS` status in `admin/system-health.html` has `title` or `aria-label` reason text.
+- PASS: targeted source check verified exactly one runtime table hook.
+- PASS: targeted source check verified the server mask marker list includes all required tokens.
+- PASS: Playwright verified runtime keys are displayed alphabetically.
+- PASS: Playwright verified secret-like test env values are masked in both rendered page text and client-visible Admin System Health API response bodies.
+- PASS: Playwright verified non-admin sessions do not call Admin System Health status or storage connectivity endpoints.
+- PASS: `npx playwright test tests/playwright/tools/AdminHealthOperationsPage.spec.mjs --config=codex_playwright_system_chrome.config.cjs --project=playwright` (3 passed)
+- PASS/WARN: Playwright V8 coverage report lists changed browser runtime JS `assets/theme-v2/js/admin-system-health.js`; `src/dev-runtime/server/local-api-router.mjs` is reported as advisory WARN because Playwright V8 coverage does not collect server-side runtime files.
+
+## Playwright Coverage Notes
+
+- `docs_build/dev/reports/playwright_v8_coverage_report.txt`
+- `docs_build/dev/reports/coverage_changed_js_guardrail.txt`
+- Changed browser runtime JS coverage: `(90%) assets/theme-v2/js/admin-system-health.js - executed lines 227/227; executed functions 28/31`
+- Advisory warning: `(0%) src/dev-runtime/server/local-api-router.mjs - changed runtime JS file was not collected by Playwright V8 coverage; advisory only`
+- Coverage is advisory only; no threshold is enforced.
+
+## Skipped Lanes
+
+- Full samples smoke: skipped by request because this Admin diagnostics runtime PR does not touch samples.
+- Full Playwright suite: skipped because the targeted Admin System Health route/behavior spec covers the changed page, browser runtime module, and server status payload behavior.
+- R2 diagnostics validation beyond the existing targeted Admin page spec: skipped because PR015 already covered R2 runtime wiring and PR016 touched only runtime environment visibility.
+- Postgres diagnostics validation beyond the existing targeted Admin page spec: skipped because PR014 already covered Postgres runtime wiring and PR016 touched only runtime environment visibility.

++Confirmed:
++- Theme V2 CSS remains the only page stylesheet.
++- Page remains table-first where practical.
++- Environment Summary includes DEV, IST, UAT, and PRD.
++- Database Health is Postgres-only and includes host, port, database, migration version, and status.
++- Storage Health names Cloudflare R2 and includes bucket, list, read, write, and delete.
++- Runtime Environment displays variables alphabetically and masks secret values.
++- Limits & Capacity includes DB size, connections, storage, Class A ops, and Class B ops.
++- Diagnostics Log includes PASS, WARN, and FAIL.
++- The page no longer imports `assets/theme-v2/js/admin-system-health.js`.
++- The page no longer renders storage action buttons.
++- No runtime code was changed.
++- No persistence was added.

++## Validation Notes
++
++Targeted Admin page validation was run because the existing Admin System Health route coverage was updated for the new foundation behavior.
++
++Commands run:
++- `git diff --check`
++- Static `rg` checks for requested page sections and prohibited page patterns.
++- `npx playwright test tests/playwright/tools/AdminHealthOperationsPage.spec.mjs --config=codex_playwright_system_chrome.config.cjs --project=playwright`
++
++Skipped lanes:
++- Full samples smoke was not run because samples are outside this Admin page foundation scope.
++- Full Playwright suite was not run because targeted Admin route coverage was sufficient for the changed route.

++
++## Summary
++
++This PR creates the Admin System Health foundation as a static Theme V2 Admin page.
++
++Scope completed:
++- Reworked `admin/system-health.html` into a table-first foundation view.
++- Added Environment Summary rows for DEV, IST, UAT, and PRD.
++- Added Postgres-only Database Health rows for host, port, database, migration version, and status.
++- Added Cloudflare R2 Storage Health rows for bucket, list, read, write, and delete.
++- Added Runtime Environment rows with alphabetically displayed variables and masked secret values.
++- Added Limits & Capacity rows for DB size, connections, storage, Class A ops, and Class B ops.
++- Added Diagnostics Log rows for PASS, WARN, and FAIL.
++- Removed the page-specific Admin System Health API module from the page.
++- Removed page storage action buttons.
++- Updated existing Admin System Health Playwright route coverage for the new foundation view.

++# PR_26171_GAMMA_012 Manual Validation Notes
++
++## Manual Review Notes
++
++- Reviewed `admin/system-health.html` after the cleanup.
++- Confirmed diagnostics no longer includes the fake failure row that said no active failure was declared.
++- Confirmed intentionally unwired foundation items use `PENDING` instead of `WARN`.
++- Confirmed every `PENDING` status has `title` and `aria-label` reason text.
++- Confirmed `PASS` is used for declared facts such as DEV/IST/UAT/PRD, Postgres provider, default Postgres port, masked secret display, and the known environment target list.
++- Confirmed Postgres-only wording remains in Database Health.
++- Confirmed Cloudflare R2 wording remains in Storage Health.
++- Confirmed no SQLite wording appears in the Admin System Health page.
++- Confirmed no page-local CSS, inline script, inline style, persistence, or Admin System Health API wiring was added.
++
++## Validation Notes
++
++- `git diff --check` passed.
++- Targeted static status validation passed.
++- Existing targeted Admin System Health Playwright route spec passed with 3 tests.
++- Samples were not run because samples are outside this queued status cleanup scope.
++
++## User Review Focus
++
++- Review whether `PENDING` is the desired final wording for intentionally unwired health checks.
++- Review the reason text in hover/accessibility attributes for clarity.
++- Confirm owner approval before any EOD merge.

-+# PR_26171_018-local-api-startup-diagnostics
-+
-+## Purpose
-+Improve `npm run dev:local-api` startup diagnostics without changing server startup behavior.
-+
-+## Implementation
-+- Replaced the compact `.env loaded for API runtime (...)` line with an `Environment Variables` section.
-+- Prints one `.env` runtime variable per line, sorted alphabetically.
-+- Uses `+` for variables applied from `.env` and `-` for variables already set before `.env`.
-+- Masks values for keys containing `PASSWORD`, `SECRET`, `TOKEN`, `KEY`, `SERVICE_ROLE`, or `JWT`.
-+- Redacts URL username/password credentials before printing non-masked URL values.
-+- Added an `All Runtime Ports being used by Service` section covering live site, API server, configured API URL, DB/Postgres, Supabase, and storage ports, with `not configured` for missing optional ports.

-+## Changed Files

++# PR_26171_GAMMA_012-admin-system-health-status-reason-cleanup
++
++## Summary
++
++Queued scope 012 was applied to the existing draft PR #36 workstream branch:
++
++- PR #36: `PR_26171_GAMMA_011-admin-system-health-foundation`
++- Branch: `team/GAMMA/admin`
++
++This queued scope cleans up Admin System Health foundation status semantics without creating a separate GitHub PR.
++
++## Scope Evidence
++
++- Removed the fake `FAIL` diagnostics row.
++- Removed foundation placeholder `WARN` statuses from `admin/system-health.html`.
++- Kept declared foundation facts as `PASS`, including deployment target rows, Postgres provider, masked secret display, and known environment target list.
++- Used `PENDING` for intentionally unwired foundation checks and metrics.
++- Added `title` and `aria-label` reason text to every non-`PASS` health status cell.
++- Preserved Postgres-only wording.
++- Preserved Cloudflare R2 wording.
++- Kept the page static and Theme V2-only.
++- Did not add persistence, API wiring, or SQLite.
++
++## Instruction Start Gate
++
++- Instructions read: PASS
++- `docs_build/dev/PROJECT_INSTRUCTIONS.md`: read before edits
++- `docs_build/dev/PROJECT_MULTI_PC.txt`: read before edits
++- Current branch: `team/GAMMA/admin`
++- Clean status before edits: PASS
++- Local/remote sync before edits: PASS (`0 0`)
++- TEAM token: `GAMMA`
++- TEAM ownership: PASS by explicit Master Control/user assignment for diagnostics/admin workstream
++- Implementation path: `admin/system-health.html`
++- Existing draft PR target: PR #36
++- Separate PR creation: SKIP by explicit user instruction
++- Merge: SKIP, owner-controlled EOD approval remains required
++
++Note: the merged instruction file still contains the older main-only branch guard. This queued update proceeded only after explicit user instruction to continue on `team/GAMMA/admin` and update existing draft PR #36 rather than creating a separate PR.
++
++## Validation
++
++- PASS: `git diff --check`
++- PASS: targeted Admin System Health source check found 28 status cells and 16 non-`PASS` statuses with reasons.
++- PASS: targeted source check found no fake failure text, no `WARN`/`FAIL` health status cells, and no SQLite text in `admin/system-health.html`.
++- PASS: targeted source check verified Postgres and Cloudflare R2 wording remains present.
++- PASS: `npx playwright test tests/playwright/tools/AdminHealthOperationsPage.spec.mjs --config=codex_playwright_system_chrome.config.cjs --project=playwright` (3 passed)
++
++## Skipped Lanes
++
++- Full samples smoke: skipped by request because this status cleanup does not touch samples.
++- Full Playwright suite: skipped because the existing targeted Admin System Health route spec covers the changed page behavior.
++- Runtime/API validation: skipped because no API wiring or runtime persistence was added.

++# PR_26171_GAMMA_014 Manual Validation Notes
++
++## Manual Review Notes
++
++- Reviewed `admin/system-health.html` after adding Postgres diagnostics hooks.
++- Confirmed the page still uses Theme V2 only and keeps scripts external.
++- Confirmed the Database Health table remains Postgres-only.
++- Confirmed the runtime module reads only the safe Admin System Health status API.
++- Confirmed the runtime module renders provider, host, port, database, migration summary, and connection status.
++- Confirmed no storage action buttons or R2 connectivity controls were introduced in PR014.
++- Confirmed no client-side secret values, database URLs, access keys, or secret keys are rendered.
++- Confirmed non-`PASS` status cells include hover/accessibility reason text.
++- Confirmed no SQLite runtime or persistence code was introduced.
++
++## Validation Notes
++
++- `git diff --check` passed.
++- Targeted Admin System Health source validation passed.
++- Targeted Admin System Health Playwright route/behavior spec passed with 3 tests.
++- Playwright V8 coverage report includes `assets/theme-v2/js/admin-system-health.js`.
++- Samples were not run because samples are outside this queued Admin diagnostics scope.
++
++## User Review Focus
++
++- Review whether the Postgres connection and migration wording is the desired admin-facing phrasing.
++- Review whether WARN/PENDING semantics are acceptable when local Postgres is not configured.
++- Confirm owner approval before any EOD merge.

++# PR_26171_GAMMA_014-admin-postgres-diagnostics-runtime
++
++## Summary
++
++Queued scope 014 was applied to the existing draft PR #36 workstream branch:
++
++- PR #36: `PR_26171_GAMMA_011-admin-system-health-foundation`
++- Branch: `team/GAMMA/admin`
++
++This queued scope wires the Admin System Health Postgres diagnostics table to the existing safe Admin System Health status API without creating a separate GitHub PR.
++
++## Scope Evidence
++
++- Added stable Postgres table hooks in `admin/system-health.html`.
++- Loaded `assets/theme-v2/js/admin-system-health.js` as an external Theme V2 module.
++- Replaced the old unused broad controller with a focused current-page renderer.
++- Used the existing safe API contract through `readAdminSystemHealthStatus()`.
++- Rendered provider, host, port, database, migration summary, and connection status.
++- Preserved Postgres-only database direction.
++- Kept Cloudflare R2 and runtime diagnostics outside PR014 runtime wiring.
++- Left diagnostics as `PENDING` only when the safe status API is unavailable or refuses to render.
++- Preserved masked secret display and did not expose database URLs, passwords, keys, tokens, or storage credentials.
++- Did not introduce SQLite, new persistence, storage action wiring, inline CSS, or inline JavaScript.
++
++## Safe Backend Contract
++
++- Existing safe contract found: `GET /api/admin/system-health/status`.
++- Existing browser API client found: `src/api/admin-system-health-api-client.js`.
++- Existing server payload includes `databaseStatus` with safe host, port, database name, migration counts, last migration metadata, and status fields.
++- Existing payload flags `secretEditingAllowed: false` and `secretsExposed: false`; the page refuses to render runtime diagnostics if either safe-secret condition is violated.
++
++## Instruction Start Gate
++
++- Instructions read: PASS
++- `docs_build/dev/PROJECT_INSTRUCTIONS.md`: read before edits
++- `docs_build/dev/PROJECT_MULTI_PC.txt`: read before edits
++- Current branch: `team/GAMMA/admin`
++- Clean status before edits: PASS
++- Local/origin sync before edits: PASS (`0 0`)
++- TEAM token: `GAMMA`
++- TEAM ownership: PASS by explicit Master Control/user assignment for diagnostics/admin workstream
++- Implementation path: `admin/system-health.html`, `assets/theme-v2/js/admin-system-health.js`, `tests/playwright/tools/AdminHealthOperationsPage.spec.mjs`
++- Existing draft PR target: PR #36
++- Separate PR creation: SKIP by explicit user instruction
++- Merge: SKIP, owner-controlled EOD approval remains required
++
++Note: the merged instruction file still contains older main-only guard wording. This queued update proceeded only after explicit user instruction to continue on `team/GAMMA/admin` and update existing draft PR #36 rather than creating a separate PR014 GitHub PR.
++
++## Validation
++
++- PASS: `git diff --check`
++- PASS: targeted source check found no SQLite references in `admin/system-health.html` or `assets/theme-v2/js/admin-system-health.js`.
++- PASS: targeted source check verified every static non-`PASS` status in `admin/system-health.html` has `title` or `aria-label` reason text.
++- PASS: targeted source check verified PR014 did not add storage connectivity action wiring.
++- PASS: Playwright verified the admin page calls `/api/admin/system-health/status`.
++- PASS: Playwright verified the admin page does not call `/api/admin/system-health/storage-connectivity-action`.
++- PASS: Playwright verified non-admin sessions do not call the Admin System Health status endpoint.
++- PASS: Playwright verified the page does not expose full Postgres URLs or configured secret values.
++- PASS: `npx playwright test tests/playwright/tools/AdminHealthOperationsPage.spec.mjs --config=codex_playwright_system_chrome.config.cjs --project=playwright` (3 passed)
++- PASS: Playwright V8 coverage report lists changed runtime JS file `assets/theme-v2/js/admin-system-health.js`.
++
++## Playwright Coverage Notes
++
++- `docs_build/dev/reports/playwright_v8_coverage_report.txt`
++- `docs_build/dev/reports/coverage_changed_js_guardrail.txt`
++- Changed runtime JS coverage: `(93%) assets/theme-v2/js/admin-system-health.js - executed lines 104/104; executed functions 13/14`
++- Coverage is advisory only; no threshold is enforced.
++
++## Skipped Lanes
++
++- Full samples smoke: skipped by request because this Admin diagnostics runtime PR does not touch samples.
++- Full Playwright suite: skipped because the targeted Admin System Health route/behavior spec covers the changed page and runtime module.
++- Storage/R2 runtime action validation: skipped because PR014 only wires Postgres diagnostics.
++- Runtime environment dynamic visibility validation: skipped because PR016 owns runtime environment wiring.
++

++# PR_26171_GAMMA_015-admin-r2-diagnostics-runtime
++
++## Summary
++
++Queued scope 015 was applied to the existing draft PR #36 workstream branch:
++
++- PR #36: `PR_26171_GAMMA_011-admin-system-health-foundation`
++- Branch: `team/GAMMA/admin`
++
++This queued scope wires Admin System Health Cloudflare R2 diagnostics to existing safe status and storage connectivity contracts without creating a separate GitHub PR.
++
++## Scope Evidence
++
++- Added stable R2 table hooks in `admin/system-health.html`.
++- Extended `assets/theme-v2/js/admin-system-health.js` to render safe R2 bucket configuration.
++- Used existing `runAdminSystemHealthStorageConnectivityAction()` for R2 list/write/read/delete diagnostics.
++- Displayed bucket configured state, list check, read check, write check, and delete check.
++- Kept the table-first Admin System Health presentation.
++- Did not add storage action buttons.
++- Did not expose endpoint credentials, access keys, secret keys, tokens, or secret values.
++- Did not introduce SQLite, new persistence code, new storage services, inline CSS, or inline JavaScript.
++
++## Safe Backend Contract
++
++- Existing safe status contract found: `GET /api/admin/system-health/status`.
++- Existing safe storage action contract found: `POST /api/admin/system-health/storage-connectivity-action`.
++- Existing action IDs used:
++  - `storage-list`
++  - `storage-write-test-object`
++  - `storage-read-test-object`
++  - `storage-delete-test-object`
++- The existing backend returns `secretEditingAllowed: false` and `secretsExposed: false`; the page keeps any unsafe response as `PENDING` instead of rendering it.
++- The write/read/delete checks use the existing temporary storage connectivity object contract and do not add new persistence code.
++

++- PASS: targeted source check verified R2 diagnostics use the existing safe API client action.
++- PASS: targeted source check found no direct secret value fields in the Admin System Health runtime module.
++- PASS: Playwright verified the admin page calls `/api/admin/system-health/status`.
++- PASS: Playwright verified the admin page calls `/api/admin/system-health/storage-connectivity-action` four times for Admin sessions.
++- PASS: Playwright verified non-admin sessions do not call status or storage connectivity endpoints.
++- PASS: Playwright verified no full Postgres URL or configured secret values are exposed.

++## Playwright Coverage Notes

++- Confirmed non-secret loaded keys are displayed as `configured` rather than exposing raw values.
++- Confirmed Runtime Environment rows render alphabetically from server-owned data.
++- Confirmed non-`PASS` status cells include hover/accessibility reason text.
++- Confirmed no SQLite runtime or persistence code was introduced.
++
++## Validation Notes
++
++- `git diff --check` passed.
++- Targeted Admin System Health source validation passed.
++- Targeted Admin System Health Playwright route/behavior spec passed with 3 tests.
++- Playwright verified test env secret values were absent from both page text and client-visible Admin System Health API response bodies.
++- Playwright V8 coverage report includes `assets/theme-v2/js/admin-system-health.js`.
++- Playwright V8 coverage report warns that `src/dev-runtime/server/local-api-router.mjs` is server-side and not collected by browser V8 coverage.
++- Samples were not run because samples are outside this queued Admin diagnostics scope.
++
++## User Review Focus
++
++- Review whether listing all loaded runtime environment key names is the desired Admin visibility level.
++- Review whether non-secret env values should remain `configured` only, as implemented, to avoid accidental exposure.
++- Confirm owner approval before any EOD merge.

++# PR_26171_GAMMA_016-admin-runtime-environment-runtime
++
++## Summary
++
++Queued scope 016 was applied to the existing draft PR #36 workstream branch:
++
++- PR #36: `PR_26171_GAMMA_011-admin-system-health-foundation`
++- Branch: `team/GAMMA/admin`
++
++This queued scope wires Admin System Health runtime environment visibility through the existing safe Admin System Health status endpoint without creating a separate GitHub PR.
++
++## Scope Evidence
++
++- Added a server-owned runtime environment payload to `GET /api/admin/system-health/status`.
++- Displayed loaded runtime environment keys alphabetically in the Runtime Environment table.
++- Returned safe display states only:
++  - `configured`
++  - `not configured`
++  - `********` for secret-like keys
++- Masked keys containing:
++  - `PASSWORD`
++  - `SECRET`
++  - `TOKEN`
++  - `KEY`
++  - `SERVICE_ROLE`
++  - `JWT`
++  - `DATABASE_URL`
++- Added runtime table rendering in `assets/theme-v2/js/admin-system-health.js`.
++- Preserved Postgres-only database direction and R2-only storage direction.
++- Did not expose raw runtime values in the API response or page.
++- Did not introduce SQLite, new persistence, inline CSS, or inline JavaScript.
++
++## Safe Backend Contract
++
++- Extended existing safe status contract: `GET /api/admin/system-health/status`.
++- The server payload includes runtime key names, configured state, masked display text, status, and reason text.
++- The server payload does not include raw environment variable values.
++- The payload includes `secretEditingAllowed: false` and `secretsExposed: false`.
++- The browser refuses to render runtime rows if the runtime environment payload reports unsafe secret controls.
++
++## Instruction Start Gate
++
++- Instructions read: PASS
++- `docs_build/dev/PROJECT_INSTRUCTIONS.md`: read before queued edits
++- `docs_build/dev/PROJECT_MULTI_PC.txt`: read before queued edits
++- Current branch: `team/GAMMA/admin`
++- Clean status before PR016 edits: PASS
++- Local/origin sync before PR016 edits: PASS (`0 0`)
++- TEAM token: `GAMMA`
++- TEAM ownership: PASS by explicit Master Control/user assignment for diagnostics/admin workstream
++- Implementation path: `src/dev-runtime/server/local-api-router.mjs`, `admin/system-health.html`, `assets/theme-v2/js/admin-system-health.js`, `tests/playwright/tools/AdminHealthOperationsPage.spec.mjs`
++- Existing draft PR target: PR #36
++- Separate PR creation: SKIP by explicit user instruction
++- Merge: SKIP, owner-controlled EOD approval remains required
++
++## Validation
++
++- PASS: `git diff --check`
++- PASS: targeted diff check verified PR016 introduced no SQLite text.
++- PASS: targeted diff check verified PR016 introduced no raw env value field such as `value: env[...]`, `rawValue`, or `actualValue`.
++- PASS: targeted source check verified every static non-`PASS` status in `admin/system-health.html` has `title` or `aria-label` reason text.
++- PASS: targeted source check verified exactly one runtime table hook.
++- PASS: targeted source check verified the server mask marker list includes all required tokens.
++- PASS: Playwright verified runtime keys are displayed alphabetically.
++- PASS: Playwright verified secret-like test env values are masked in both rendered page text and client-visible Admin System Health API response bodies.
++- PASS: Playwright verified non-admin sessions do not call Admin System Health status or storage connectivity endpoints.
++- PASS: `npx playwright test tests/playwright/tools/AdminHealthOperationsPage.spec.mjs --config=codex_playwright_system_chrome.config.cjs --project=playwright` (3 passed)
++- PASS/WARN: Playwright V8 coverage report lists changed browser runtime JS `assets/theme-v2/js/admin-system-health.js`; `src/dev-runtime/server/local-api-router.mjs` is reported as advisory WARN because Playwright V8 coverage does not collect server-side runtime files.
++
++## Playwright Coverage Notes
++
++- `docs_build/dev/reports/playwright_v8_coverage_report.txt`
++- `docs_build/dev/reports/coverage_changed_js_guardrail.txt`
++- Changed browser runtime JS coverage: `(90%) assets/theme-v2/js/admin-system-health.js - executed lines 227/227; executed functions 28/31`
++- Advisory warning: `(0%) src/dev-runtime/server/local-api-router.mjs - changed runtime JS file was not collected by Playwright V8 coverage; advisory only`
++- Coverage is advisory only; no threshold is enforced.
++
++## Skipped Lanes
++
++- Full samples smoke: skipped by request because this Admin diagnostics runtime PR does not touch samples.
++- Full Playwright suite: skipped because the targeted Admin System Health route/behavior spec covers the changed page, browser runtime module, and server status payload behavior.
++- R2 diagnostics validation beyond the existing targeted Admin page spec: skipped because PR015 already covered R2 runtime wiring and PR016 touched only runtime environment visibility.
++- Postgres diagnostics validation beyond the existing targeted Admin page spec: skipped because PR014 already covered Postgres runtime wiring and PR016 touched only runtime environment visibility.
