fix(release): repair functions.php + ARCHITECTURE.md truncations from prior commit

The prior commit (4a506e1c) was assembled from a sandbox bash mount that returned a truncated view of two files. Net effect: - functions.php was cut at line 235, dropping the closing of peptide_starter_inline_dark_mode_script() and its add_action registration. wp_head dark-mode script was effectively removed. - ARCHITECTURE.md was cut mid-paragraph and lost its Version section. Both files are now rebuilt from main + minimum-delta patches: - functions.php: +4 minimal additions (perf-asset-policy @see, version bump, require_once, add_action). Dark-mode script preserved. - ARCHITECTURE.md: +3 lines (perf-asset-policy in inc/ tree, version banner bumped). Version section preserved. - style.css, CHANGELOG.md, CONVENTIONS.md: also rebuilt from main + targeted patches as a safety measure (no functional change vs the prior commit, just guaranteed-untruncated). Verified: every file ends with a trailing newline; functions.php contains the dark-mode add_action; ARCHITECTURE.md contains the Version section.

chore(release): wire perf-asset-policy bootstrap, bump v1.6.0, update docs

+# Agent Operating Standard — peptiderepo
+
+**Version:** 1.0.0
+**Effective:** 2026-04-14
+**Applies to:** every AI agent (Claude, Copilot, Cursor, future tools) working in any peptiderepo codebase.
+
+This document is the single source of truth for *how* agents must work in peptiderepo repos. It travels with the code — every repo contains a copy at its root and a `CLAUDE.md` pointer that requires reading this file before any edit.
+
+If this document conflicts with a per-repo `CONVENTIONS.md`, this document wins for **process**; `CONVENTIONS.md` wins for **code style**.
+
+---
+
+## 1. The QA Gate — Non-Negotiable
+
+**No code reaches `main` without a signed QA verdict for its commit SHA.**
+
+The QA reviewer is a separate Claude subagent (the `qa-review` skill) with no prior conversation context. The agent that wrote the code cannot be the agent that approves it. This is enforced by the deploy skills — they refuse to push if no signed `APPROVE` verdict exists for the SHA being deployed.
+
+Verdicts are written to `qa-reviews/<repo>/<YYYY-MM-DD>-<sha>.md` in the workspace root and signed with: commit SHA, reviewer model string, ISO-8601 timestamp, and verdict.
+
+### Verdict types
+
+- `APPROVE` — ship it.
+- `APPROVE-WITH-P2-NOTES` — ship it; create follow-up tickets for the noted P2/P3 issues.
+- `REJECT-P1` — do not ship; fix the listed issues and re-submit.
+- `REJECT-P0` — do not ship; the change has a security, data-loss, or production-impact risk that must be resolved before any further work on the branch.
+
+### Severity definitions
+
+- **P0:** secrets exposure, auth bypass, data loss, production-down risk, unauthorized financial cost (e.g., uncapped LLM spend).
+- **P1:** Definition-of-Done violation, missing input sanitization or output escaping, missing authorization on a sensitive action, missing test for new core logic, schema change without migration.
+- **P2:** AI-readability gap (missing docblock, file >300 lines, magic value), inconsistent naming, missing `@see` cross-reference.
+- **P3:** style nit, opinion-level suggestion.
+
+---
+
+## 2. Definition of Done — every change must satisfy
+
+The QA reviewer runs this checklist against the diff. Any unchecked item is at minimum a P1.
+
+- [ ] Code follows the language/framework's standard coding conventions (per-repo `CONVENTIONS.md`)
+- [ ] All input sanitized at boundary, all output escaped at render
+- [ ] Authentication and authorization checks on all sensitive actions
+- [ ] No hardcoded secrets — credentials live in env or config only
+- [ ] All external API calls have error handling, timeout, and retry-with-backoff (max 3 retries)
+- [ ] Cost/token impact documented for any AI-touching feature; budget hard-stop respected
+- [ ] Unit tests for new core logic; integration tests for framework-specific behavior
+- [ ] User-facing strings are translatable/localizable
+- [ ] Consistent namespace/prefix on all global identifiers
+- [ ] Teardown/uninstall path cleans up ALL project data
+- [ ] Every new class has a preamble docblock (what / who triggers / dependencies)
+- [ ] Every new public method has typed params, return type, and docblock noting side effects
+- [ ] No magic methods, dynamic resolution, or clever indirection without explicit justification
+- [ ] No file exceeds 300 lines (split if it does)
+- [ ] `ARCHITECTURE.md` and `CONVENTIONS.md` updated if the change affects file structure, data flow, or patterns
+- [ ] `@see` cross-references at top of files participating in multi-class flows
+- [ ] Event/hook docblocks list known listeners and where they're registered
+- [ ] Commits authored as `peptiderepo` (not `ongterence` or any personal identity)
+
+---
+
+## 3. Git Workflow — PR-Gated, Soft-Enforced
+
+All four peptiderepo repos are private on the GitHub free plan, which does not support branch protection. The review gate is enforced at the agent layer via these rules.
+
+### Rules
+
+1. **Never push to `main` directly.** Every change lands via a pull request. No self-merging from agents. No force-pushing to `main`.
+2. **Branch naming:** `claude/<scope>-<YYYYMMDD>` — e.g., `claude/cost-tracker-20260414`.
+3. **Commit trailer:** every commit ends with `Agent-Session: <session-id-or-description>` so commits correlate back to the conversation that produced them.
+4. **PR description template:**
+   - **What changed** (one paragraph)
+   - **Why** (motivation or incident link)
+   - **Risk flags** (schema changes, API contract changes, cost impact, compatibility)
+   - **Test plan** (what was run locally; what Terence should smoke-test after merge)
+   - **QA verdict path** (`qa-reviews/<repo>/<date>-<sha>.md`)
+5. **Emergency push exception:** if the situation genuinely requires pushing to `main` without a PR (site down, CI broken, one-line hotfix), ask Terence in chat first. Every emergency push gets a follow-up PR for the audit trail.
+
+### Mechanics
+
+`gh` CLI is not installed in the Cowork sandbox. Use `curl` with the PAT from `.env.credentials` (workspace root). See `pr-workflow-rollout/project-instructions-addendum.md` for the exact `curl` snippet.
+
+---
+
+## 4. Security Non-Negotiables
+
+- Sanitize all input at the boundary; escape all output at render.
+- Authenticate and authorize every sensitive action.
+- Secrets in environment/config only — never hardcoded, never committed, never exposed to the browser.
+- Use a consistent namespace/prefix on all global identifiers.
+- All paid-API calls happen server-side only.
+
+---
+
+## 5. Cost-Conscious AI Integration

+Any feature that calls a paid LLM/AI API must:

+- Respect a token/dollar budget with a **hard stop** when exhausted.
+- Log every call: timestamp, provider, model, prompt tokens, completion tokens, estimated cost.
+- Use the cheapest model that does the job; expensive models only where required and configurable.
+- Cache identical calls within a configurable window.
+- Use structured output (JSON mode) when the API supports it.
+- Batch where possible.
+- Offer dry-run mode for user-facing operations.
+- Fail with retry-and-backoff (max 3); never retry indefinitely.
+
+---
+
+## 6. AI-Readability Requirements
+
+This codebase is maintained by AI agents. Code must be optimized for LLM comprehension.
+
+- Files under 300 lines. Split when they grow.
+- Every class has a preamble: *what / who triggers / dependencies*.
+- Every public method has typed params, return type, and a docblock listing side effects.
+- Names are verb-noun and unambiguous (`generate_post_from_topic()`, not `process()`).
+- Constants over magic values (`MAX_RETRIES`, not `3`).
+- Event/hook names describe the event (`before_content_generation`, not `hook_1`).
+- No clever indirection — flat, explicit call chains.
+- Inline comments explain *why*, not *what*.
+- `@see` cross-references at the top of files in multi-class flows.
+
+---
+
+## 7. Documentation as Code
+
+Every change that touches structure or data flow must include doc updates **in the same commit**:
+
+- New file → add to `ARCHITECTURE.md` file tree.
+- New pattern → update `CONVENTIONS.md`.
+- New external integration → update `ARCHITECTURE.md` integrations section.
+- Non-obvious decision → add to `ARCHITECTURE.md` "key decisions".
+
+Documentation that drifts from reality actively misleads the next agent. QA will reject changes that modify structure without updating docs (P1).

+
+`peptide_starter_get_client_ip()` trusts in this priority order:
+
+1. **`HTTP_CF_CONNECTING_IP`** — only when `REMOTE_ADDR` is itself

+   Direct-to-origin connections that bypass Cloudflare cannot forge this
+   header because their peer IP is not a CF edge.
+2. **`HTTP_X_FORWARDED_FOR`** — ignored by default. Opt in via
+   `add_filter( 'peptide_starter_trust_xff', '__return_true' )` only
+   when a known, trusted non-CF proxy fronts the origin.
+3. **`REMOTE_ADDR`** — always trusted as the final fallback. Cannot be
+   client-controlled at the TCP layer.
+
+`inc/cloudflare-ips.php` holds a static snapshot of CF ranges. Refresh

+## [1.6.0] - 2026-04-23 — Mobile Performance Phase 1
+
+Mobile-perf optimization targeting LCP reduction through conditional asset
+dequeue, font weight slimming, and font server preconnect. Measured baseline
+LCP on Moto G Power (Slow 4G): 5.4s; target after Phase 1: ~2.5s.
+
+### Added
+
+- `inc/perf-asset-policy.php` — five-function module:
+  - `peptide_starter_perf_dequeue_plugin_assets()` — dequeues WooCommerce,
+    Elementor, and Ultimate Social Media Icons assets on pages that don't
+    use them. Hook: `wp_enqueue_scripts` priority 100.
+  - `peptide_starter_perf_slim_google_fonts()` — `style_loader_src` filter;
+    rewrites Roboto and Roboto Slab `family=` queries to keep only weights
+    actually used (400/500/700 + 400/700). Drops 72 font faces to 5.
+  - `peptide_starter_perf_resource_hints()` — `wp_resource_hints` filter;
+    adds preconnect hints for `fonts.googleapis.com` and `fonts.gstatic.com`.
+  - `peptide_starter_perf_defer_cookie_notice()` — `script_loader_tag` filter;
+    appends `defer` attribute to the cookie-notice front-end script.
+  - `peptide_starter_page_uses_elementor( int $post_id )` — helper.
+- Kill-switch constant `PEPTIDE_STARTER_PERF_DEQUEUE` (default `true`).
+  Define `false` in `wp-config.php` to disable all dequeues instantly.
+- Filterable handle lists: `peptide_starter_perf_woocommerce_handles`,
+  `peptide_starter_perf_elementor_handles`, `peptide_starter_perf_usmi_handles`,
+  `peptide_starter_perf_font_weights`.
+- `tests/test-perf-asset-policy.php` — 13 unit-test cases covering kill-switch,
+  per-page-context dequeue logic, font slim happy/edge cases, filter overrides,
+  preconnect insertion, defer attribute application.
+
+### Changed
+
+- `style.css` Version header bumped 1.5.2 → 1.6.0.
+- `PEPTIDE_STARTER_VERSION` constant bumped to `1.6.0`.
+
+### Why
+
+PageSpeed Insights mobile score on `https://peptiderepo.com/` was 74 with
+LCP 5.4s, FCP 2.6s. Desktop scored ~95 — the gap was mobile-specific
+(weaker CPU + slower network amplify the cost of 13 render-blocking CSS
+files in `<head>`, of which the homepage actually needed at most 4).
+Phase 1 trims the asset graph for non-shop pages without touching plugin
+code or template files.
+
+## [1.5.2] - 2026-04-14 — Security
+
+Same-day follow-up to v1.5.1. Closes four issues the v1.5.1 post-merge
+review flagged — two ship-blockers (PSEC-007 CF header spoof, PSEC-008
+synchronous migration) and two mediums (PSEC-009 timing oracle,
+PSEC-010 test-coverage gap). All fixes stay within ADR-0001's decision
+envelope — no new ADR required.
+
+### Security fixes
+
+- **PSEC-007** — `peptide_starter_get_client_ip()` now only trusts
+  `HTTP_CF_CONNECTING_IP` when `REMOTE_ADDR` itself is inside a
+  published Cloudflare edge range. Direct-to-origin requests (which
+  Hostinger allows) can no longer forge their source IP by sending a
+  `CF-Connecting-IP` header. `HTTP_X_FORWARDED_FOR` is ignored unless
+  explicitly opted in via the `peptide_starter_trust_xff` filter. New
+  module `inc/cloudflare-ips.php` holds the range snapshot (dated
+  2026-04-14) + a CIDR matcher for both IPv4 and IPv6. Override the
+  list via the `peptide_starter_cloudflare_ip_ranges` filter.
+- **PSEC-008** — Removed the v1.5.1 re-verification migration entirely
+  (Option A). Existing subscribers are now grandfathered — treated as
+  verified. Verification applies to accounts registered from v1.5.2
+  onward. The `admin_init`-driven synchronous `wp_mail` loop that blocked
+  wp-admin is gone; its `ps_verify_migration_version` option is cleared
+  on theme activation.
+- **PSEC-009** — Registration validation no longer short-circuits.
+  Pattern / email / password / `username_exists` / `email_exists` all
+  evaluate unconditionally before the combined rejection, closing the
+  response-time enumeration oracle that distinguished microsecond-fast
+  regex rejection from DB-round-trip rejection.
+
+### Tests
+
+- `test-rate-limiter.php` — seven new cases covering CF-peer trust,
+  spoofed-header rejection, invalid-value fallthrough, XFF default-off
+  behaviour, XFF filter opt-in, filter override of the CF range list,
+  IPv6 CIDR matching, and family-mismatch rejection.
+- `test-auth-handlers.php` — `test_register_runs_all_checks_even_when_early_one_fails`
+  asserts DB-backed user lookups still execute when a cheap validation
+  check has already failed (PSEC-009).
+- `test-email-verification.php` — `test_valid_token_verifies_user_clears_meta_and_fires_hook`
+  covers the happy-path verify flow end-to-end including hook firing
+  (PSEC-010).
+
+### Documentation
+
+- `ARCHITECTURE.md` — CF IP trust model explained in the Security
+  Summary; migration decision (grandfather) documented.
+- `CONVENTIONS.md` — new "Trust model for request headers" note.
+
+### Rollback note
+
+If v1.5.2 causes login or registration failures, roll back to v1.5.0
+(not v1.5.1 — v1.5.1 carried the unresolved PSEC-007 hole and the
+blocking migration). Rate-limit transients auto-expire.

+## QA gate

-Theme path on server: `~/domains/peptiderepo.com/public_html/wp-content/themes/peptide-starter/`
+Before any deploy, the `qa-review` skill spawns a fresh subagent to review the diff against `AGENT-OPERATING-STANDARD.md`. The verdict is written to `qa-reviews/<repo>/<date>-<sha>.md` in the workspace root and must be `APPROVE` or `APPROVE-WITH-P2-NOTES` for the deploy to proceed.

-## Architecture
-
-This is a classic WordPress theme (no block/FSE). All styling is in `style.css` (no build step, no preprocessor). JavaScript is vanilla — no bundler.
-
-### Key files
-
-| File | Purpose |
-|------|---------|
-| `style.css` | All theme CSS (~44KB). Organized: reset → tokens → typography → globals → components → regions → pages → animations → a11y → dark mode → responsive |
-| `functions.php` | Theme setup, script enqueueing, Customizer registration, nav walker, helper functions |
-| `front-page.php` | Home page: hero section → PRAutoBlogger widget → Peptide News feed |
-| `header.php` | Global header with nav, dark mode toggle, mobile menu |
-| `footer.php` | 4-column widget footer with copyright |
-| `archive-peptide.php` | Peptide CPT archive grid |
-| `single-peptide.php` | Single peptide detail page |
-| `assets/js/navigation.js` | Mobile menu and nav functionality |
-| `assets/js/theme.js` | Dark mode toggle, theme utilities |
-
-### Template parts
-
- `template-parts/content.php` — Post/page content loop
- `template-parts/content-peptide.php` — Peptide card in archive
- `template-parts/content-none.php` — Empty state
-
-## Coding Conventions
-
- **PHP**: WordPress coding standards — tabs for indentation, Yoda conditions, braces on same line
- **CSS**: No preprocessor. Use CSS custom properties (defined in `:root`). All theme classes prefixed `.ps-`
- **JS**: Vanilla ES6+, no build step. Files in `assets/js/` must pass `node --check`
- **No `!important`** on global elements — prevents plugin conflicts
- Plugin CSS namespaces are untouched (`.pn-*` for Peptide News, `.psa-*` for Peptide Search AI, `.prab-*` for PRAutoBlogger)
-
-## Design System
-
- **Font**: Inter (Google Fonts) with system fallback
- **Scale**: 1.125x modular, 8px grid base
- **Primary color**: `#0066CC` (light) / `#3B82F6` (dark)
- **Breakpoints**: 480px, 768px, 1024px, 1440px (mobile-first)
- **Dark mode**: CSS custom properties swap via `html[data-theme="dark"]` or `prefers-color-scheme: dark`
-
-## Plugin Integration
-
-The theme integrates with three companion plugins via shortcodes, all wrapped in `shortcode_exists()` for graceful degradation:
-
-1. **Peptide Search AI** (`[peptide_search]`) — AI search in hero section
-2. **Peptide News** (`[peptide_news]`) — News feed on front page
-3. **PRAutoBlogger** (`[prautoblogger_posts]`) — Auto-generated research articles on front page
-
-## Customizer Options
-
-Editable via Appearance → Customize:
- Hero title, subtitle, search placeholder
- Footer copyright text
- Dark mode default on/off
-
-## Version
-
-Current: **v1.3.1** (defined in `style.css` header and `PEPTIDE_STARTER_VERSION` constant in `functions.php`)
-
-When bumping version, update both locations.

+## How to add a performance policy rule
+
+When adding a new asset-perf rule (e.g., a new plugin's CSS to dequeue on
+non-relevant pages, or a new font family to slim):
+
+1. **For dequeues:** edit `inc/perf-asset-policy.php`. Add the plugin's
+   handle list to a new function (or extend the existing arrays via the
+   matching filter — `peptide_starter_perf_<plugin>_handles`). Hook the
+   new dequeue function on `wp_enqueue_scripts` priority 100, gated by
+   `PEPTIDE_STARTER_PERF_DEQUEUE` and a context predicate (e.g.,
+   `is_front_page()`, `! is_woocommerce()`).
+
+2. **For font slimming:** add the family to the default array in
+   `peptide_starter_perf_slim_google_fonts()`, or override at runtime
+   via the `peptide_starter_perf_font_weights` filter. Specify only
+   weights actually used by the design system; defaulting to "all weights"
+   defeats the purpose.
+
+3. **For new resource hints:** extend `peptide_starter_perf_resource_hints()`
+   with the new domain in the `preconnect` array. WP renders the
+   `<link>` tag automatically; don't echo your own.
+
+4. **For deferring third-party scripts:** add the script handle to the
+   list in `peptide_starter_perf_defer_cookie_notice()` (or rename the
+   function if it grows beyond cookie-notice).
+
+5. **Always add a test case** in `tests/test-perf-asset-policy.php`
+   covering the new rule's happy path AND its negation (the page-context
+   where the rule must NOT apply). The dequeue logic is silent if a
+   handle name is wrong — only tests catch this before deploy.
+
+6. **Verify on production handles** before committing. Plugin handle
+   names are not always what you'd guess. SSH to Hostinger and run
+   `wp eval 'global $wp_styles; do_action("wp_enqueue_scripts");
+   foreach($wp_styles->registered as $h=>$o){echo $h.PHP_EOL;}'` to
+   dump the actual handle names.

+## Trust model for request headers (v1.5.2)
+
+Never trust `HTTP_X_FORWARDED_FOR`, `HTTP_CF_CONNECTING_IP`, or any other
+client-controlled header without first validating the peer. Always read
+the client IP via `peptide_starter_get_client_ip()` — it handles the
+Cloudflare-peer check, the XFF opt-in, and the `REMOTE_ADDR` fallback.
+
+If a new feature needs to trust a different proxy header (e.g. a new CDN
+in front of CF):
+
+1. Add the upstream proxy's IP ranges to a new file under `inc/`.
+2. Extend `peptide_starter_get_client_ip()` with a new validated branch
+   guarded by a filter defaulted to off.
+3. Never accept a header whose source can't be validated at the TCP
+   layer.
+
+Refresh the Cloudflare range snapshot in `inc/cloudflare-ips.php`
+quarterly. Out-of-band bumps go through the
+`peptide_starter_cloudflare_ip_ranges` filter.

peptiderepo	a54b5c90a8	fix(release): repair functions.php + ARCHITECTURE.md truncations from prior commit The prior commit (`4a506e1c`) was assembled from a sandbox bash mount that returned a truncated view of two files. Net effect: - functions.php was cut at line 235, dropping the closing of peptide_starter_inline_dark_mode_script() and its add_action registration. wp_head dark-mode script was effectively removed. - ARCHITECTURE.md was cut mid-paragraph and lost its Version section. Both files are now rebuilt from main + minimum-delta patches: - functions.php: +4 minimal additions (perf-asset-policy @see, version bump, require_once, add_action). Dark-mode script preserved. - ARCHITECTURE.md: +3 lines (perf-asset-policy in inc/ tree, version banner bumped). Version section preserved. - style.css, CHANGELOG.md, CONVENTIONS.md: also rebuilt from main + targeted patches as a safety measure (no functional change vs the prior commit, just guaranteed-untruncated). Verified: every file ends with a trailing newline; functions.php contains the dark-mode add_action; ARCHITECTURE.md contains the Version section.

peptiderepo	4a506e1c56	chore(release): wire perf-asset-policy bootstrap, bump v1.6.0, update docs Round 2 follow-up to `6da83981` — wires the perf module into the theme, bumps style.css + PEPTIDE_STARTER_VERSION constant to 1.6.0, and adds [1.6.0] CHANGELOG section + ARCHITECTURE listing + CONVENTIONS how-to. Without this commit the perf-asset-policy.php file from Round 1 is dead code; the bootstrap require + after_setup_theme action are added in functions.php.

peptiderepo	d2577b8371	fix: display featured images at full width, centered The theme was rendering featured images at WordPress 'medium' size (300×300 square crop) instead of the full 1200×632 original. Changed the_post_thumbnail() from 'medium' to 'full' and added responsive CSS that scales images to 100% content width with centered alignment.

peptiderepo	3eb6c13bf0	ci(deploy): tolerate 403 on post-deploy health check (#10 ) The peptide-starter-theme v1.5.2 release added peptide_starter_is_cloudflare_peer() — a CF-peer IP validator that correctly rejects direct-to-origin requests as non-Cloudflare traffic with HTTP 403. The deploy workflow's post-deploy health check makes exactly such a request from a GHA runner IP, so it now reliably receives 403 even on successful deploys. Two deploys today (peptide-starter-theme v1.5.2, prautoblogger Commit 1a) both succeeded but reported workflow failure due to this. The actual deploys (rsync + cache purge) ran clean; site verified HTTP 200 from real traffic both times. Fix: accept either 200 (normal healthy response) or 403 (validator actively rejecting non-CF origin — itself a positive liveness signal) in the health check. Reject only on 5xx, 4xx-other, or connection failure. Reverting this fix is correct only if we either (a) bypass the validator for our own health-check user-agent, or (b) route the health check through Cloudflare. Both are larger changes for a later release. Agent-Session: cowork-deploy-healthcheck-fix-20260415 Co-authored-by: peptiderepo <peptiderepo@users.noreply.github.com>	2026-04-15 20:17:24 +07:00

peptiderepo	000c21a9e8	feat(ci): add Neurometric PR-Summarizer as 4th QA voice (#9 ) Neurometric markets a task-specialized PR-Summarizer SLM (Qwen3-4B + specialist system prompt) on a free tier. Adding it as a 4th voice in the existing A/B reviewer panel to see whether a specialized small model catches things the 3 general-purpose voices miss. The SLM does not honor OpenAI tool-calling, so it cannot return our structured submit_review schema. Wired as a "prose voice": - MODELS tuple gains a 6th provider_type field ("openrouter_tools" \| "neurometric_prose") - call_model() dispatches; new call_neurometric_prose() path hits api.neurometric.ai/v1 without tools, embeds raw markdown output, and infers verdict from keyword heuristic - Render branch in PR comment marks the verdict as heuristic and notes tokens/cost are not tracked (free tier) - Never the primary voice; heading still driven by Haiku Also hardens the shared render path against models that omit the optional 'summary' field (rev.get('summary') fallback). Requires new repo secret NEUROMETRIC_API_KEY (already set on all four peptiderepo repos). Voice self-skips with inline error if missing.

peptiderepo	c960aee16d	ci: reviewer cost cap + 3-model A/B harness (#5 ) * ci: cost cap + 3-model A/B harness on CTO reviewer Two enhancements to the PR reviewer: 1. Monthly spend cap: tracked in Repo Variables (CTO_REVIEW_MONTH, CTO_REVIEW_SPEND_CENTS, CTO_REVIEW_CAP_CENTS). Default cap $10/month. Auto-resets on month rollover. Posts a skip-comment on PRs when cap hit. 2. A/B harness: reviews every PR with 3 models in parallel (Claude Haiku 4.5, DeepSeek V3.1, Kimi K2 Thinking). Comment shows all 3 verdicts side-by-side so we can compare quality/cost on real PRs before picking a permanent default. Drop to 1 model by editing the MODELS list after A/B window closes. Agent-Session: cowork-reviewer-ab-20260414 * ci: use CTO_ADMIN_TOKEN for repo variables + restore formal APPROVE/REQUEST_CHANGES Default GITHUB_TOKEN cannot mutate Repository Variables (always 403). Use a PAT-backed secret CTO_ADMIN_TOKEN for the budget counter steps. Also restores formal APPROVE/REQUEST_CHANGES verdicts now that repo setting can_approve_pull_request_reviews is enabled. Agent-Session: cowork-reviewer-ab-20260414 * ci: address review feedback — per-model timeout + simpler cost math - Per-model timeout of 60s so one hung model does not block siblings - Simplify cost_cents math (cost_usd * 100 directly, no double-rounding) Defer: fine-grained PAT for CTO_ADMIN_TOKEN (requires manual OAuth device flow). Agent-Session: cowork-reviewer-ab-20260414 * ci: stop exposing CTO_ADMIN_TOKEN as env var (security cleanup) Pass the PAT only via github-token param. continue-on-error on the budget step so a missing/expired secret degrades gracefully instead of failing the whole workflow.

peptiderepo	fff3fce432	v1.5.2: CF-peer validated client IP, grandfather migration, de-short-circuit register Security follow-up to v1.5.1. Closes four items from the v1.5.1 review — two ship-blockers and two mediums — all within the ADR-0001 envelope. PSEC-007 — peptide_starter_get_client_ip() now trusts CF-Connecting-IP only when REMOTE_ADDR falls inside a published Cloudflare edge range. Previously, any direct-to-origin request (which Hostinger permits) could forge its rate-limit key by setting the header to a different IP per attempt, bypassing every abuse control in the theme. New module inc/cloudflare-ips.php embeds a dated snapshot of CF v4/v6 ranges and a CIDR matcher covering both families; list is overridable via the peptide_starter_cloudflare_ip_ranges filter for out-of-band updates. HTTP_X_FORWARDED_FOR stays ignored unless operators opt in via the peptide_starter_trust_xff filter. PSEC-008 — Removed the v1.5.1 user-verification migration (Option A as confirmed by peptiderepo). The sync-wp_mail-per-subscriber loop on admin_init would have blocked wp-admin and hammered deliverability. Existing accounts are now grandfathered: no ps_pending_verification meta = verified. Verification applies only to registrations from v1.5.2 forward. The ps_verify_migration_version option (written by v1.5.1) is cleared on theme activation. PSEC-009 — Registration validation no longer short-circuits. All five checks (username pattern, email validity, password length, username_exists, email_exists) evaluate unconditionally before the combined rejection. Closes the response-time oracle that let an attacker distinguish microsecond-fast regex rejection from DB-round-trip rejection and infer which field triggered the failure. PSEC-010 — Added the happy-path verify test that v1.5.1 was missing. Covers token match, user meta cleanup, auth cookie set, and the peptide_starter_user_verified action firing with the correct user ID. Seven new rate-limiter tests confirm CF-peer validation works end-to-end: trusted CF peer honours the header, untrusted peer ignores spoofed headers, invalid values fall through, XFF default-off, XFF filter opt-in, CF range filter override, IPv6 CIDR match, family mismatch rejection. Confirmed with peptiderepo before coding: (1) Option A for PSEC-008 because zero users; (2) Cloudflare IS in front of the origin (dig confirms 104.21.x / 172.67.x + CF-Ray response header), so PSEC-007 is a real fix not dead code; (3) no staging — treat prod as staging. ARCHITECTURE.md gains a client-IP trust model section; CONVENTIONS.md documents the header-trust rules for future modules. Version bumped to 1.5.2 in style.css and functions.php.
