+# Remote SSH copy — HELD, do not publish
+
+**Status:** removed from the `freno-dev` source on 2026-10-29 in the FRE-323
+correction, and **not yet off the live site** — the deploy is blocked on a write
+credential to `mikefreno/freno-dev` (card `82d1e1b7`). `nook.freno.me` still
+serves every sentence below until that push or a Vercel deploy lands.
+**Owner:** CMO. **Verified by:** CTO, on the FRE-320/FRE-205 work.
+**Restore only when:** FRE-320/FRE-205 ship a genuinely one-click install, the CTO
+verifies that flow, and a recording shows a remote agent joining the island.
+Until then this file is the only home for these sentences.
+
+## What was removed
+
+### 1. Landing collage tile
+
+Source: `src/components/nook/FeatureCollage.tsx` (removed 2026-10-29).
+
+```
+kicker: Remote
+title:  Agents on other machines
+body:   Run agents on Linux boxes and SSH servers — one click installs the
+        nook-hook, and their sessions join the same island.
+```
+
+The mock attached to it showed two session rows whose agent chips named
+`build-box` and `gpu-rig`.
+
+### 2. Landing feature breakdown section
+
+Source: `src/components/nook/FeatureBreakdowns.tsx` (removed 2026-10-29).
+
+```
+kicker: Remote
+title:  Any SSH box, one click away
+body:   Pick a host from your ssh config or your tailnet and click once — the
+        nook-hook installs itself and its agents appear beside your local ones,
+        indistinguishable.
+
+bullets:
+- One click: connect, push the hook, configure agents, check it can reach this Mac
+- Hosts mirror this Mac's installed integrations automatically
+- Remote sessions are ordinary rows; the agent chip names the machine
+```
+
+The section's demo animated a `gpu-rig` host moving from "Not set up" through
+`connecting` → `pushing the hook binary` → `configuring agents` → `checking the
+host can reach this Mac` → `Live`, then showed a remote session row.
+
+### 3. Approvals bullet
+
+Source: `src/components/nook/FeatureBreakdowns.tsx` (removed 2026-10-29).
+
+```
+- Works across every hooked agent, local or remote
+```
+
+### 4. Feature chip
+
+Source: `src/components/nook/IslandExtras.tsx` (removed 2026-10-29).
+
+```
+One-click SSH setup
+```
+
+## What replaced it
+
+Nothing. The Remote tile and section were removed rather than replaced; the
+existing Approvals cell already carries the verified local claim:
+
+> Approve an agent's tool call from your Mac's notch, and the agent carries on.
+
+## Restore checklist
+
+1. FRE-320/FRE-205 have shipped the one-click install and removed the
+   `~/.ssh/config` / `ssh-copy-id` friction described in FRE-320.
+2. The CTO has verified the shipping flow and the evidence is on FRE-320.
+3. A recording exists showing a remote agent joining the island.
+4. CMO restores the copy above, then owns the launch plan for it — with an
+   owner and date per item — before anything goes back on the site.

+# Why the remote claim is parked
+
+The site was selling a setup path a buyer does not get.
+
+FRE-320 measured today's actual path (2026-10-29): the one-click flow is
+app-UI-only, needs a hand-edited `~/.ssh/config` for any host not already in ssh
+config or on the tailnet, needs a one-time `ssh-copy-id` because the app runs ssh
+with `BatchMode=yes`, and has no manual fallback for minting the per-host
+credential. FRE-315 and FRE-322 §3 correction 4 marked the remote claim
+unverified and demo-gated. The CTO named it the largest launch risk because it
+was already in front of buyers.
+
+So the `freno-dev` source now says only what the product can back today: local
+agents, the card, and the notch. That correction is committed locally and is
+**not deployed** — the live page still carries the remote sentences until the
+push in FRE-323 card `82d1e1b7` lands. The remote story is not deleted — it is
+parked here with the FRE-320/FRE-205 work so it can return the day the one-click
+install ships and is recorded.
+
+## What has to be true before it returns
+
+| Requirement | Owner | Date |
+|---|---|---|
+| One-click install ships without hand-edited `~/.ssh/config` or `ssh-copy-id` | FRE-320/FRE-205 engineering | When FRE-320/FRE-205 ships |
+| CTO verifies the shipping flow and records the evidence on FRE-320 | CTO | Same day, before any copy moves |

+| Restore copy and rebuild the launch plan with an owner + date per item | CMO | Day the three rows above are true |

+
+**trial started: 0 → 2 (+2).**
+
+## Before acting on these numbers
+
+- **291 of 291 rows in the window predate the FRE-366 instrumentation.** They carry no host, and their recorded address is the production proxy's loopback (127.0.0.1 / ::1) — the writers then recorded the direct peer, not the visitor. They are excluded from every host-scoped stage above (visits, and the download click/served split), and "unique visitors" over them still collapses to one host. Rows recorded since carry the site they addressed and the visitor's address truncated to a prefix (/24, or /56 for IPv6 — the FRE-369 privacy floor), so "unique visitors" counts networks, not machines.
+- **Download rows are automation-heavy.** Of this window's 137 download rows, 0 are clicks and 0 are served files; the remaining 137 predate the click/served stage label and cannot be split, so they count in neither stage. 112 of all 137 are not browser user agents (curl, Sparkle, link-preview crawlers).
+- **No conversion rate before the cohort matures.** Trial→paid belongs to the mature Day 28–35 read (FRE-197); a ratio from a partial cohort is not a metric.

 ### 3. Honest privacy scoping
 
-Telemetry and the trial email **do** leave the device. The defensible claim is:
+Telemetry and the licence check **do** leave the device: Sentry runs on **every
+launch, unconditionally** (with the Mac's IP address via `sendDefaultPii`), and the
+trial check sends `IOPlatformUUID` and the device name to `freno.me` ([FRE-322]
+§2.4, corrected by [FRE-354] `(b)`). Never publish, in any wording:

-Never "no data leaves the device".
+The one favourable engine sentence — about the **hook and bridge only**, never
+"The Nook" — as corrected by [FRE-354] `(j)`: the hook and bridge **are not a cloud
+service**. Do not write "talk to nothing but your Mac" (too absolute: the
+`NOOK_PORTS` fan-out resolves `host.docker.internal` and the default gateway, and
+`defaultGateway()` opens a no-packet UDP socket to `8.8.8.8:80`), and do not narrow
+it to "over SSH" (a tailnet peer dials directly).
+
+It is verified as a code fact ([FRE-322] §2, [FRE-354] `(j)`), and it is still
+**held** until the disclosures land: Sentry gated behind a preference or removed,
+and `/privacy` + `/faq` corrected against the egress inventory (patch on branch
+`faq/from-objections-2026-10-29`, verified by [FRE-354]). A true sentence next to
+false ones is worse than no sentence.
 
 ### 4. Sell what works today
 
-Phone approvals are deferred until a shipped iOS app exists — no "(coming soon)"
-parentheticals. The launch story is remote SSH: agents running on other machines,
-visible and unblockable from the Mac's notch.
+An iPhone + Apple Watch companion **is** in users' hands as a TestFlight beta
+(`ios-v0.3.2`, 2026-10-22; [FRE-354] open question). That makes one thing true and
+one thing forbidden: say "TestFlight beta" when the phone exists in a sentence at
+all, and never claim approvals-from-phone as a shipped capability without its own
+CTO verdict — no "(coming soon)" parentheticals either way.
+
+Remote SSH is **held**, not approved: the one-click install has not
+been verified end to end ([FRE-315] §1) and the shipped path needs hand-edited
+`~/.ssh/config` and a one-time `ssh-copy-id` ([FRE-320]). Its copy stays parked in

+ *
+ * FRE-323 took the remote story off the site because it was unverified and
+ * demo-gated (FRE-315, FRE-320, FRE-322 §3 correction 4): the "one click
+ * installs the nook-hook" flow is app-UI-only, needs a hand-edited
+ * `~/.ssh/config` for any host not already in ssh config or on the tailnet,
+ * needs a one-time `ssh-copy-id` because the app runs ssh with
+ * `BatchMode=yes`, and has no manual fallback for minting the per-host
+ * credential. FRE-359 verdict B removed the coverage count for the same
+ * reason: the /agents table lists 13 of the registry's 18 rows.
+ *
+ * FRE-997 corrects the second half without touching the first. The count was
+ * stale, not unverifiable: `AgentSpec.all` holds eighteen, /agents now lists
+ * all eighteen and `agents.test.ts` asserts that roster as an equality again.
+ * So the two completeness phrasings FRE-359 banned ("every coding agent",
+ * "Supported agents") no longer rest on a 13-of-18 gap — the ban existed
+ * because the page claimed the set and listed two thirds of it. They are out
+ * of `BANNED_COVERAGE` on this branch for that reason alone; the stale counts
+ * stay banned, and every FRE-323 remote sentence stays banned, because this
+ * branch still carries the FRE-323 site state.
+ *
+ * The copy was not thrown away — it is parked in

+                  search, your speech is converted to text by Apple&apos;s
+                  speech recognition. Apple may process it on its servers. The

+                  code on your screen for them to scan. It goes from one phone

+/**
+ * The client address and the site a request addressed, for the analytics
+ * writers (FRE-366).
+ *
+ * Until this existed every writer called `getRequestIP` and only looked at
+ * `x-forwarded-for` when it returned null — so behind the production proxy the
+ * recorded address was the proxy itself, and all 12,035 addressed rows in
+ * VisitorAnalytics carried 127.0.0.1 / ::1.
+ *
+ * STANDING RULE (FRE-369, the security review of that change): nothing here is
+ * a security signal. The address is a *best guess at a visitor*, not an
+ * authenticated identity — do not import it into auth, rate limiting, abuse
+ * control, fraud checks, or anything that grants or denies access. A caller
+ * that needs a security decision must re-derive trust for its own stakes; the
+ * blast radius of a wrong answer here is a poisoned analytics row, and that is
+ * the only reason the shortcuts below are acceptable.
+ *
+ * Trust boundary, stated plainly: `x-forwarded-for` is client-controlled text.
+ * It is believed only when the direct peer is a loopback address — the
+ * production shape, where a same-host proxy (nginx/caddy) terminates TLS and
+ * sets the header itself. Anywhere else the direct peer IS the client (dev,
+ * direct hit) and a forwarded header from it is ignored as spoofable.
+ *
+ * Which hop is the visitor (FRE-369 finding Q1): the request arrives as
+ * `client → Cloudflare → same-host origin proxy → app`, and both proxies
+ * *append*. So `x-forwarded-for` reaches us as
+ * `<client-supplied spoof…>, <true client>, <Cloudflare edge>` and the leftmost
+ * hop is exactly the one the sender chose — the original FRE-366 read took it
+ * and was wrong. Order of preference:
+ *
+ *   1. `cf-connecting-ip` — Cloudflare *overwrites* this header, so a
+ *      client-supplied value never survives the edge. Authoritative.
+ *   2. `x-forwarded-for`, counted from the right: drop the rightmost hop (the
+ *      Cloudflare edge address the origin proxy appended) and take the one
+ *      before it. Never the leftmost.
+ *   3. the direct peer, as before.
+ *
+ * h3's own `getRequestIP(event, { xForwardedFor: true })` also takes the
+ * leftmost hop, so it is not a fix for this and must not be swapped in.
+ *
+ * Residual caveat, deliberately not papered over: step 2 assumes the pinned
+ * topology (one trusted proxy above us, i.e. Cloudflare). Behind a *single*
+ * forwarding proxy that does not set `cf-connecting-ip`, a client that sent its
+ * own `x-forwarded-for` sits at the hop we read. That is why the value is only
+ * ever stored truncated (see `truncateIpAddress`) and why it stays out of every
+ * security path. Deploy-side precondition this repo cannot verify: the origin
+ * must be reachable only from Cloudflare (origin firewall / authenticated
+ * origin pull). If it is directly reachable, an attacker can set every header
+ * in this file and no read here can recover the truth.

+/**
+ * The client address, resolved for security decisions (FRE-371).
+ *
+ * This is the ONLY client-IP read allowed to feed a security decision — rate
+ * limiting, abuse quotas, account lockout, audit trails. It exists separately
+ * from `request-client.ts`'s `resolveClientIp` (the analytics read) on
+ * purpose:
+ *
+ *   - `resolveClientIp` carries a standing rule (FRE-369 review, 1d9287a):
+ *     it never feeds a security decision. Its blast radius is a poisoned
+ *     analytics row; ours is granting or denying access.
+ *   - Rate limiting needs the UN-truncated address; the analytics module only
+ *     ever hands out truncated prefixes.
+ *   - `request-client.ts` ships on FRE-366's branch, which is under review;
+ *     a security fix must not merge-depend on an analytics diff.
+ *
+ * The address-parsing primitives below are therefore a deliberate port of the
+ * reviewed ones, not an import. If the two ever drift, this file's version is
+ * the one security paths follow.
+ *
+ * WHY the old read was spoofable: `security.ts`'s `getClientIP` took the
+ * LEFTMOST `x-forwarded-for` hop, believing the header "cannot be spoofed".
+ * In the pinned topology — client → Cloudflare → same-host origin proxy →
+ * app — both proxies *append*, so the header arrives as
+ * `<client-supplied spoof…>, <true client>, <Cloudflare edge>` and the
+ * leftmost hop is exactly the one the sender chose. Rotating
+ * `X-Forwarded-For: <random>` per request minted a fresh rate-limit bucket
+ * and unlimited bug-report quota. `x-real-ip` was read unconditionally too;
+ * nothing in this topology overwrites it, so it is equally client text and is
+ * no longer read at all.
+ *
+ * Trust order (matches the convention FRE-366 landed after its security
+ * review, re-derived here for security stakes):
+ *
+ *   1. The direct socket peer, when it is a real routable address: it IS the
+ *      client (dev, direct hit), and any forwarded header from it is the
+ *      client describing itself — ignored.
+ *   2. `cf-connecting-ip` — reachable only when the peer is the loopback
+ *      origin proxy (or unreadable, e.g. a synthetic event in tests).
+ *      Cloudflare *overwrites* this header at the edge, so a client-supplied
+ *      value never survives. Must parse as an address.
+ *   3. `x-forwarded-for` counted from the RIGHT: drop the rightmost hop (the
+ *      Cloudflare edge address the origin proxy appended) and take the hop
+ *      before it. Never the leftmost. Must parse as an address.
+ *   4. "unknown" — callers give unknown-IP keys stricter shared limits, so
+ *      an unresolvable client fails toward a tighter bucket, never a looser
+ *      one.
+ *
+ * Deploy-side precondition this code cannot verify (same as the analytics
+ * read): the origin must be reachable only through Cloudflare and the
+ * same-host proxy. If the app is directly internet-reachable, a client can
+ * set every header read here and no in-app read can recover the truth.

+/**
+ * The weekly funnel reading: `marketing/metrics/weekly.md`'s data half.
+ *
+ * The funnel the marketing cluster agreed on is
+ *
+ *   visit → download click → DMG served → trial started → checkout started
+ *         → purchase → activation
+ *
+ * and this module reads it from the two live databases, plus the campaign
+ * dimension the /analytics page already exposes through
+ * `getAnalyticsSummary.topCampaigns`.
+ *
+ * Two properties matter more than the numbers:
+ *
+ *  - It takes both connections as arguments. `~/server/analytics` imports the
+ *    full server env (Stripe keys, Apple secret, licence key …); the weekly
+ *    job only needs the two databases, and must be runnable from a checkout
+ *    whose `.env` carries nothing else. The SQL here is the same shape as the
+ *    analytics summaries, so the weekly read and the dashboard cannot drift
+ *    into different label sets.
+ *  - Every stage is measured by its own label. FRE-366 gave the funnel that:
+ *    the download door and the DMG file route record distinct `stage` values
+ *    (`click` / `served`), a created Stripe checkout session records its own
+ *    row, and every row carries the real client address and the host it
+ *    addressed, so the visit stage scopes to the Nook. Rows that predate
+ *    that instrumentation are stated next to the numbers, never silently
+ *    counted (see `renderWeeklyMarkdown`).
+ *
+ * No `~/env`, no `~/server/database`: the caller owns the connections, the
+ * tests own an in-memory SQLite, and the script owns the libsql clients.
