Add community node protocol spec, Agent Skills, and make the failing tests hermetic

Community nodes (Phase 1 of plan.md): the protocol specification in
services/nodes/spec.py as the single source of truth, GET /nodes/spec.json,
a generated protocol docs page, the Community nodes API docs group, and the
implementation plan plus the residential proxy research. The no-open-proxy rule
is enforced in the spec (open_proxy cannot be set).

Agent Skills: register the Skills API docs group, cascade skills on account
deletion, add the nested CLAUDE.md, README and routes docs, and cover the
parser, the fetcher (end to end against a mock origin), the data layer and the
routes with 73 unit and 16 api tests.

Tests made hermetic with the repo's existing patterns instead of ambient
environment: embeddings tests set OPENROUTER_API_KEY via monkeypatch, the
workspace tests install FakeBackend via runtime.set_backend, and the skills
install tests use run_async. DockerCliBackend now returns 127 (command not
found) when the CLI is missing instead of raising FileNotFoundError, so a host
without docker answers with a clean error rather than a 500. The Providers tab
empty state no longer names the Model routes tab.

+# Podman deployment (rootless, no docker daemon)
+
+Hosts without a docker daemon (like `devplace`) run the stack with the Python
+`podman-compose` plus the `docker-compose.podman.yml` overlay. The base
+`docker-compose.yml` is unchanged and stays the file rootful `docker compose`
+uses; the overlay only adjusts what rootless podman needs.
+
+## Commands
+
+Always go through the make targets - they pin both `-f` files. A bare
+`podman-compose up -d` drops the overlay and recreates a crashing app (see
+"Why the overlay exists").
+
+```bash
+make podman-build           # build images (only when pyproject/Dockerfiles change)
+make podman-up              # start (also warns if user linger is off)
+make podman-reload          # restart workers on new code (bind-mounted, no rebuild)
+make podman-ps              # container status
+make podman-logs            # tail output
+make podman-down            # stop
+```
+
+Open `http://<host>:${PORT}` (default 10500, published on 127.0.0.1 for the
+front proxy). Source-only changes need just `make podman-reload`.
+
+## Why the overlay exists
+
+The base file runs the app as `user: 1000:1000`, which is correct for rootful
+docker (container uid 1000 == host uid 1000). Under **rootless** podman the
+default userns instead maps container uid 1000 to a subordinate host uid
+(100999), which cannot write the bind-mounted checkout (owned by host uid
+1000) - uvicorn dies on startup with
+`PermissionError: ... '/app/data/locks/devplace-init.lock'`, the app never
+turns healthy, and nginx (which waits on `service_healthy`) never starts.
+
+The overlay sets `user: "0:0"` for the app: container root maps back to the
+invoking host user under rootless, restoring write access while staying
+unprivileged on the host. (`userns_mode: keep-id` would also fix the mapping
+but podman rejects `--userns` together with `--pod`, and podman-compose puts
+all services in one pod.)
+
+## One compose tool only
+
+Use the Python `podman-compose` (`/usr/bin/podman-compose`) for this stack,
+never mix it with native `podman compose` in the same project directory. They
+use different container names (`devplace_app_1` vs `devplace-app-1`) and would
+create a second stack fighting over port 10500.
+
+## Surviving reboots
+
+Both services use `restart: unless-stopped`, but rootless containers only
+restart after a reboot if the host user's systemd linger is enabled:
+
+```bash
+loginctl show-user "$(id -un)" | grep Linger   # want: Linger=yes
+sudo loginctl enable-linger "$(id -un)"        # fix if off
+```
+
+`make podman-up` prints a warning when linger is off.
+
+## Known differences from docker
+
+- The admin-only **Container Manager** needs the docker socket, which does not
+  exist on podman hosts. The `[containers] docker ps failed: [Errno 2]` lines
+  in the app log are expected noise, not an error; serving the site is
+  unaffected.
+- `make docker-attach` / the containers overlay do not apply here.
+
+## Troubleshooting
+
+- `PermissionError ... /app/data/...` on boot: the app was (re)created
+  without the overlay. Run `make podman-up` (it recreates with the fix).
+- `up` hangs with no output: it is waiting on the app healthcheck. In another
+  shell run `podman logs devplace_app_1` - a crash loop there is the cause.
+- `Error: --userns and --pod cannot be set together`: a `userns_mode`
+  override is in play; remove it, this stack relies on `user: "0:0"`.
+- Port 10500 already in use: a second stack (other compose tool, or bare-metal
+  `make prod`) is running. `podman ps -a` plus `ss -tlnp` show the conflict.

+## Skills
+
+Members can install [Agent Skills](https://agentskills.io) from a URL at `/skills` so Devii can use them. A skill is a `SKILL.md` (YAML frontmatter plus markdown instructions) with optional text files under `scripts/`, `references/` and `assets/`. Skills are private to their owner, count against a per-user cap, and only the name and a one-line description of enabled skills are added to Devii's system prompt; Devii loads the full text on demand. A skill is untrusted third-party text: it can never grant Devii a tool, bypass a confirmation or run a script. Deleting a skill is a soft delete and needs confirmation when Devii does it. Documented in the API docs under *Skills* and in `devplacepy/services/skills/CLAUDE.md`.
+
+## Community nodes (planned, specification only)
+
+Members will be able to opt in to donate a little of their connection to the DevPlace community, so search can reach sites that block datacenter addresses. **Today only the specification exists:** `GET /nodes/spec.json` and the [Node network protocol](/docs/nodes-protocol.html) docs page, both generated from `devplacepy/services/nodes/spec.py`. No account can donate yet and nothing connects.
+
+What is fixed already, because the specification enforces it: nobody is enrolled by default; a node is not an open proxy and only ever contacts a short published allowlist of websites, on ports 80 and 443, never a private address; the refusal is enforced on the donor's machine as well as on the server; every limit is a published hard cap. The implementation plan, the measured and unmeasured claims, and the legal gate are in `plan.md`.

 ## Vibe coding (Alpha, admin only)
 
 Build software by talking to an AI agent instead of typing every line. Create a project for storage, attach a container to it (the shared `ppy` image, your files mounted at `/app`), start it, and open a terminal. The whole flow is drivable conversationally through Devii. Inside every container three agents ship preinstalled and run on **your own API key**, so all AI usage is metered to your account: **DevPlace Code (`dpc`)**, a coding agent in the same class as Claude Code; **`botje.py`**, a plug-and-play DevPlace bot you can copy and customise; and **`pagent`**, a minimal zero-dependency agent. Each container is launched with `DEVPLACE_BASE_URL`, `DEVPLACE_OPENAI_URL`, `DEVPLACE_API_KEY`, `DEVPLACE_USER_UID`, `DEVPLACE_CONTAINER_NAME`, `DEVPLACE_CONTAINER_UID`, and `DEVPLACE_INGRESS_URL` already set. Publish a container port to a public URL at `/p/<slug>` by setting an `ingress_slug` and `ingress_port` (ask Devii to do it at create time). The feature is in **Alpha** and currently limited to administrators; the full walkthrough, including a tutorial that vibes a web app and puts it online, is at `/docs/getting-started-vibing.html`.

+### Podman (rootless) hosts
+
+Hosts without a docker daemon run the same stack via `podman-compose` plus the `docker-compose.podman.yml` overlay - see [PODMAN.md](PODMAN.md) for the full notes. Short version:
+
+```bash
+make podman-build           # build the images
+make podman-up              # start (warns if user linger is off)
+```
+
+The base compose file runs the app as `user: 1000:1000`, which is wrong under rootless podman (container uid 1000 maps to a subordinate host uid that cannot write the bind-mounted checkout, so the app crashes with `PermissionError` and nginx never starts). The overlay runs the app as container root instead, which maps back to the invoking host user and stays unprivileged on the host. Always use the `make podman-*` targets - a bare `podman-compose up -d` drops the overlay and recreates the crashing container. Never mix `podman-compose` with native `podman compose` in this directory (different container names, they fight over port 10500). Reboot survival needs both `restart: unless-stopped` (already set) and systemd user linger (`sudo loginctl enable-linger <user>`); `make podman-up` warns when linger is off.

+  matches. Installing, enabling, disabling or deleting a skill takes effect on the next turn.
+- **Untrusted text.** A skill is third-party text. It guides Devii within what you asked for; it
+  never bypasses a confirmation, never grants a tool (`allowed-tools` is stored, not honoured),
+  and its scripts are stored as text and never executed automatically.
+- **Install.** Pass a direct `.../SKILL.md` URL, or a directory URL (redirects to an index page
+  are reduced to their directory and `SKILL.md` is fetched from there). Bundled files are fetched
+  only when the body references them by relative path under `scripts/`, `references/` or
+  `assets/`, on the same origin, as text, within the size and count limits. Anything skipped is
+  reported with a reason. Installing the same `name` again updates it in place.

@@ -0,0 +1,55 @@
+This file documents the community node network (`devplacepy/services/nodes/`, `devplacepy/routers/nodes/`): members opt in to donate a little of their connection so search can reach sites that block datacenter addresses. Claude Code auto-loads it whenever a file under `devplacepy/services/nodes/` is read or edited. The design record, with the measured and unmeasured claims separated, is `plan.md` at the repository root.
+
+## What exists today
+
+Only Phase 1 (the specification) is built. Everything else is planned and listed under "Gaps" next to the phase that closes it. Nothing here is enabled for any account.
+
+| Piece | File | State |
+|-------|------|-------|
+| Protocol specification | `spec.py` | built, tested |
+| `GET /nodes/spec.json` | `routers/nodes/spec.py` | built, tested, public |
+| Generated protocol docs page | `templates/docs/nodes-protocol.html` | built, reads the `nodes_spec` Jinja global |
+| API docs group | `docs_api/groups/nodes.py` | built, one endpoint |
+
+## The specification is the contract
+
+`spec.py` is the single source of truth. The server, the Go client, the browser extension, the docs page and the tests all read it. Nothing may restate a number, a frame field, an allowlisted host or a refusal code anywhere else: import it, or read it from `/nodes/spec.json`.
+
+- `ProtocolSpec` holds `version`, `min_supported`, `LimitSpec`, `FrameSpec` tuple, `DestinationSpec` tuple and `RefusalSpec` tuple. Every one is a frozen dataclass. `SPEC.describe()` is the JSON form and the only thing the router returns.
+- `open_proxy` is `field(default=False, init=False)`: it cannot be set through the constructor. **There is no open proxy mode and there will not be one.** Changing that is a protocol change that needs a new `PROTOCOL_VERSION`, not a flag.
+- `ALLOWED_PORTS` is `(80, 443)`. A `DestinationSpec` may narrow it, never widen it (a unit test fails otherwise).
+- `DestinationSpec.matches` is suffix-safe: a host matches when it equals the suffix or ends with `.` plus the suffix, so `evilreddit.com` and `reddit.com.evil.net` never match `reddit.com`.
+- `LimitSpec` is the list of hard caps from the plan. Nothing is unbounded and nothing autotunes: a constant you can read beats magic you cannot debug. A number an admin may lower becomes a `ConfigField` later; the ceiling stays here.
+- A frame type is unique per direction. An unknown type, a missing required field, an unexpected field or an oversize frame is a protocol error that closes the socket loudly, never an ignore.
+
+The docs page `nodes-protocol.html` renders its tables from the `nodes_spec` Jinja global (`templating.py`, `NODES_SPEC.describe()`), so it cannot drift from the code. `tests/api/nodes/spec.py` asserts that every frame, destination, refusal code and limit name appears on the rendered page.
+
+## Decisions taken (recorded so they are not re-litigated)
+
+| Id | Decision |
+|----|----------|
+| D1 | devplacepy owns the node fabric; rsearch is a consumer, not the home |
+| D2 | the native client is Go, one static binary per OS and architecture |
+| D3 | the extension ships as a sideloadable zip first, store submission later |
+| D4 | rewards are XP, badges and a leaderboard only: no coins, no money, nothing purchasable |
+| D5 | donors must be adults (`age_band`) |
+| D6 | a datacenter address is not a donor: residential and mobile only, admin override |
+
+## Two transports, two trust levels
+
+`tunnel` (native client) relays raw TCP so TLS runs end to end between DevPlace and the destination: the donor cannot read or forge content. `fetch` (browser extension, which has no raw sockets) lets the donor read and forge the response, so every `fetch` result is verified and labelled. A plain web page or a service worker cannot do either (CORS, no sockets) and is out of scope for good.
+
+## Gaps (what the next phases close)
+
+- Phase 2: tables, indexes, the `bandwidth_sharing` consent kind, `OWNED_TABLES` and `UNREPORTABLE_TABLES` entries, the usage ledger.
+- Phase 3: registry, session, the consent choke point, the kill switch, device and ticket routes, the lock-owner WebSocket, the nginx upgrade location.
+- Phase 4: broker, scheduler, dispatcher, destination policy, circuit breakers, result cache.
+- Phase 5 onward: the reference client, adapters, the Go client, the extension, the profile UI, Devii tools, the CLI, the privacy and donor-terms pages, the legal gate.
+- Not measured yet: Reddit and X success rates per address class, WebSocket idle timeouts through `pravda.education` and `devplace.net`, dispatcher tick cost against SQLite, socket capacity of one worker. The caps in `LimitSpec` are starting ceilings, not measurements.
+
+## Rules for work in this directory
+
+- Every user-facing or protocol-facing claim in the docs must describe what runs today. A page for an unbuilt feature states its status at the top, as `nodes-protocol.html` does.
+- A new consent is enforced at one choke point, never at call sites (see `services/moderation/CLAUDE.md`).
+- A new table here is either in `SOFT_DELETE_TABLES` or documented as derived and hard-garbage-collected; it is either in `REPORTABLE_TARGETS` or in `UNREPORTABLE_TABLES` with a reason.
+- The machine may suspend a node (reversible, timed). It may never ban a user or delete a ledger row on its own: it raises a flag for a human.

@@ -239,3 +239,37 @@ The split it enforces is the whole point:
 - owner kind `internal` / `key` / `anonymous` -> **platform processing** (news import, the bot fleet, SEO metadata, issue enhancement). Never gated: it is not the user's content.
 
 `ai_third_party` is **never granted at signup**. The existing `ai_correction_enabled` / `ai_modifier_enabled` user columns survive unchanged as *preferences* subordinate to consent: withdrawing consent turns those features off regardless of the flag, so `ai_modifier_enabled`'s default of `1` is harmless. No existing preference was flipped and no consumer changed - the gate was simply added above them. `USER_CONTENT_OWNER_KINDS` is the single tuple defining the split; widen it only if a new owner kind genuinely carries a user's own content.
+
+## Responses-protocol providers
+
+A provider row (or the default upstream) can speak the Responses API
+instead of Chat Completions. `ProviderIn.protocol` is `chat_completions`
+(default, forwarded verbatim) or `responses` (transpiled both ways).
+`chat_overlay` carries the provider choice as `gateway_upstream_protocol`;
+`gateway_upstream_protocol` is also a service config field for the
+default upstream. A responses provider's base URL ends in `/responses`
+(e.g. `https://api.meta.ai/v1/responses`); the models probe tries
+`/models` then `/muse-code/models` next to it.
+
+`responses.py` is the transpiler (stdlib only, no gateway imports):
+`chat_to_responses` / `responses_to_chat` for requests,
+`responses_object_to_chat_completion` /
+`chat_completion_to_responses_object` for objects,
+`ResponsesToChatStream` / `ChatToResponsesStream` for SSE. Every
+function returns `(converted, warnings)`; lossy mappings warn, never
+drop silently. `handle_chat` keeps reasoning about a Chat payload
+through routing/vision/precheck/fallback and transpiles at the send
+boundary (`_chat_upstream_body`), so fallbacks can cross protocols per
+attempt. Responses upstreams skip `apply_thinking`; reasoning effort
+comes from the client (`reasoning_effort`, `reasoning.effort`,
+thinking flags) or defaults to `{"effort": "minimal"}` when thinking
+is off - never `"none"`, which is not a value in the Responses
+reasoning-effort enum (confirmed by a real upstream rejecting it:
+`minimal/low/medium/high/xhigh/max`). `stream_options.include_usage`
+is never sent upstream (usage
+arrives on `response.completed`); the client's flag still controls
+the relayed usage chunk. Non-200 `{error}` envelopes and 200
+failed/incomplete Response objects are detected and relayed as
+Chat-style errors. Passthrough stays raw (no transpiling) and strips
+a trailing `/responses` base segment so `/openai/v1/responses` routes
+without doubling the path.

+This file documents Agent Skills support (`devplacepy/services/skills/`, `database/skills.py`, `routers/skills.py`, the Devii `skills` tool group): members install [Agent Skills](https://agentskills.io) packages from a URL and Devii uses them. Claude Code auto-loads it whenever a file under `devplacepy/services/skills/` is read or edited.
+
+## What a skill is here
+
+A `SKILL.md` file (YAML frontmatter with a required `name` and `description`, then a markdown body) plus optional **text** files under `scripts/`, `references/` and `assets/`. A skill is stored per user in the `skills` table, soft-deletable, private to its owner. It is **third-party text**: it guides Devii inside what the user asked for and nothing more.
+
+## Layers
+
+| Piece | File | Role |
+|-------|------|------|
+| Limits | `services/skills/limits.py` | Every cap and constant. Nothing is unbounded. |
+| Parser | `services/skills/parser.py` | Strict, dependency-free frontmatter parser (`parse_skill_md`). Rejects with a reason; never guesses. |
+| Fetcher | `services/skills/fetcher.py` | `fetch_skill(url)`: SSRF-guarded download, directory-URL resolution, bundled-file fetch. |
+| Prompt | `services/skills/prompt.py` | `skill_index_lines(user_uid)`: the bounded name+description index for the system prompt. |
+| Data | `database/skills.py` | `upsert_skill`, `get_skill_row`, `list_skills`, `set_skill_enabled`, `delete_skill`, `enabled_skill_summaries`, `skill_view`. |
+| Routes | `routers/skills.py` | `GET /skills`, `GET /skills/{name}`, `POST /skills/install`, `POST /skills/{name}/enabled`, `POST /skills/{name}/delete`. |
+| Output | `schemas/skills.py` | `SkillsOut`, `SkillPageOut`, `SkillInstallOut`, `SkillOut`, `SkillDetailOut`. |
+| Devii | `services/devii/actions/catalog/skills.py` | `install_skill`, `list_skills`, `get_skill`, `set_skill_enabled`, `delete_skill`. |
+| Docs | `docs_api/groups/skills.py` | The Skills API group (registered in `ORDERED_GROUPS`). |
+
+## Rules that must not regress
+
+- **Parsing is strict.** Flow collections, anchors, tags, multi-line quoted values, tab indentation, duplicate keys, a nested `metadata` and NUL bytes are all refused with a message that names the problem. A name is lowercase letters, digits and single hyphens. Unknown frontmatter keys are ignored with a warning, never an error.
+- **Install fetches only what the body references.** Candidates come from markdown links and code spans pointing under `scripts/`, `references/` or `assets/`. A candidate is accepted only when it is a relative, text-extension, traversal-free path on the **same origin**. Everything else lands in `skipped` with a reason shown to the user. Binary files are never stored.
+- **Every fetch goes through `net_guard.guarded_async_client`** (private, loopback and link-local addresses are refused, redirects are re-checked), bounded by `MAX_REDIRECTS`, a per-request timeout and an overall deadline. An HTML response where a `SKILL.md` was expected is an error.
+- **A skill is data, never code.** Scripts are stored as text and never executed. `allowed-tools` is stored and displayed but **never honoured**: a skill cannot grant Devii a tool or a permission. The prompt rules (`SKILLS_RULES` in `session/prompts.py`) say so to the model.
+- **Prompt cost is bounded.** Only the name and a one-line description of **enabled** skills enter the system prompt, at most `PROMPT_MAX_SKILLS` skills and `PROMPT_MAX_CHARS` characters. The body and files load on demand through `get_skill`. Only signed-in users get the block; guests never do. Installing, enabling, disabling or deleting takes effect on the next turn.
+- **Private by construction.** Every query filters by `user_uid`, so there is no "someone else's skill" to read. The one cross-user act is an administrator deleting a skill (`POST /skills/{name}/delete` with `owner=<username>`); a member naming another owner gets 403. `skills` is therefore in `UNREPORTABLE_TABLES` with that reason.
+- **Reinstalling a name updates in place** (same `uid`) and revives a soft-deleted row rather than duplicating it. The per-user cap (`SKILLS_PER_USER_MAX`) is enforced for both a new install and a revive.
+- **Soft delete and account deletion.** `skills` is in `SOFT_DELETE_TABLES` and in `deletion.OWNED_TABLES`, so deleting an account removes the member's skills under the same stamp as the rest of the event.
+- **`delete_skill` is in `CONFIRM_REQUIRED`** and declares the `confirm` parameter, as every Devii delete must.
+
+## Audit
+
+`skill.install`, `skill.update`, `skill.toggle`, `skill.delete` (category `devii`). A failed install records `skill.install` with `result="failure"` and the reason.
+
+## Tests
+
+- `tests/unit/services/skills/parser.py`, `fetcher.py`: the parser and the pure fetcher helpers, including every path-safety rejection.
+- `tests/unit/services/skills/install.py`: `fetch_skill` end to end against an `httpx.MockTransport` origin: direct and directory URLs, an index-page redirect, bundled files with skip reasons, the same-origin and traversal rules, the file count and size caps, binary files, an HTML response, HTTP errors, a blocked address and the overall deadline.
+- `tests/unit/database/skills.py`: the data layer, the cap, soft delete and revive, privacy between users, the prompt index bounds, and the registry facts (soft-deletable, unreportable, cascaded on account deletion).
+- `tests/api/skills/index.py`: auth, JSON and HTML faces, privacy, toggle, soft delete with audit, administrator deletion, member refusal, install failures including blocked addresses.
+- `tests/api/skills/install.py`: the join. The route runs in-process with `fetch_skill` replaced by a fixture, and asserts storage, the `skill.install` and `skill.update` audit rows, the failure audit row, update in place, the per-user cap and the browser redirect.
+
+## Gaps
+
+- No test installs from a live network origin. The SSRF guard refuses the loopback address a local test server would use, so the network leg (`guarded_async_client` against a real socket) is exercised only in production.

+A successful JSON login returns the account's email, API key, and admin flag,
+so one email/password call bootstraps every later request:
+
+```bash
+curl -X POST {{ base }}/auth/login \

+    "api_key": "YOUR_API_KEY",
+    "is_admin": false
+  }
+}
+```
+
+Store the `api_key` and use it as an `X-API-KEY` or Bearer credential from then
+on; there is no need to log in again. `GET /profile/{username}` with
+`Accept: application/json` reports the same picture per profile:
+`profile_is_admin` tells whether the profile owner is an admin,
+`viewer_is_admin` and `is_owner` describe the viewer, and `api_key` holds the
+profile's key only for its owner or an admin (`can_view_api_key`), null for
+everyone else.

+# Node network protocol
+
+This page is generated from the protocol specification, `services/nodes/spec.py`, the same data served at [`/nodes/spec.json`](/nodes/spec.json). The server, the clients, the tests and this page all read that one source, so the numbers below cannot drift from the code.
+
+**Status today:** the specification and `/nodes/spec.json` exist. The node socket, the device registration, the consent flow and the clients are not implemented yet. Nothing on this page is enabled for any account.
+
+## Rules that never change
+
+- **Not an open proxy.** `open_proxy` is `{{ nodes_spec.open_proxy|lower }}`. A node only ever contacts hosts on the allowlist below. Changing that is a protocol change, not a setting.
+- **Web ports only.** Ports {% for port in nodes_spec.allowed_ports %}`{{ port }}`{% if not loop.last %} and {% endif %}{% endfor %} and nothing else.
+- **The donor enforces it too.** A client refuses a request that breaks these rules even when the server asks for it, so a compromised server cannot aim a donor's machine at their own network. The refusal codes are listed below.
+- **Opt-in.** A node never connects unless the account holder granted the consent. Withdrawing it disconnects every node of that account.
+- **No cookies, no accounts.** A node never attaches the donor's cookies or logins to a request.
+
+## Version
+
+Protocol version `{{ nodes_spec.version }}`, oldest supported `{{ nodes_spec.min_supported }}`. A client announces its version in `hello`; an unsupported version is closed with code `4400`.
+
+## Transports
+
+| Mode | Used by | Who can read the content | Trust |
+|------|---------|--------------------------|-------|
+| `tunnel` | native clients | nobody on the way: TLS runs end to end between DevPlace and the destination, through the donor's socket | tampering is impossible |
+| `fetch` | browser extension | the donor can read and could forge the response | verified by structure checks and sampled redundancy, labelled `fetch` in results |
+
+## Frames
+
+Every frame is one JSON object with a `type`. An unknown type, a missing required field, an unexpected field or an oversize frame closes the socket with a reason. Direction `c2s` is client to server, `s2c` is server to client.
+

+
+| Code | Meaning |

+| `4029` | the network is at its connection capacity |
+| `4400` | protocol error or unsupported version |
+| `4403` | kicked: consent withdrawn, device revoked or suspended |
+| `1008` | policy: not authenticated |
+| `1009` | frame too large |
+
+## Limits
+
+Every number is a hard ceiling. Nothing is unbounded and nothing autotunes.
+
+| Limit | Value |
+|-------|-------|
+{% for name, value in nodes_spec.limits.items() %}| `{{ name }}` | {{ value }} |
+{% endfor %}
+
+## Destination allowlist
+

+{% endfor %}
+
+A host matches a suffix when it equals it or ends with `.` plus the suffix. `evilreddit.com` and `reddit.com.evil.net` do not match `reddit.com`.
+
+## Refusal codes
+
+A client reports one of these in `job_error` when it declines a job.
+
+| Code | Meaning |
+|------|---------|
+{% for item in nodes_spec.refusals %}| `{{ item.code }}` | {{ item.meaning }} |
+{% endfor %}
+
+## Donor-side checks
+
+Before any connection a client resolves the host itself, refuses private, loopback, link-local, CGNAT and multicast addresses, then connects to the address it resolved. It follows no redirect that leaves the allowlist. It applies the donor's own bandwidth, concurrency and schedule limits locally, even when the server sends larger ones.

+
+# IMPLEMENTATION PLAN: Community Node Network ("Donate to the DevPlace Ecosystem")
+
+Status: plan only, nothing built. Written against the repo as of 2026-10-14 and against `research_residental_proxies.md`.
+Working name: **Nodes**. Code lives in `devplacepy/services/nodes/`, routers in `devplacepy/routers/nodes/`, user-facing label "Donate to the community".
+
+## 0. Findings that change the shape of the plan
+
+These come from reading the repo and the research file. Several of them contradict the framing in the brief, so they come first.
+
+1. **There is no Jina code in this repo.** `grep -ri jina` matches only `plan.md`. The search engine is the external service `https://rsearch.app.molodetz.nl` (`crawl.RSEARCH_URL`, `services/devii/rsearch/`). The Jina fallback therefore lives in the rsearch codebase, not here. This repo only consumes rsearch from two places: `services/jobs/deepsearch/crawl.py::search_queries` and the Devii `rsearch*` tools. Where social search is implemented (here or in rsearch) is open decision D1.
+2. **The repo already knows social sites block it.** `crawl.HOSTILE_DOMAINS` lists x.com, reddit.com, instagram, facebook, linkedin, tiktok, threads, youtube and skips them. Root `CLAUDE.md` records that reddit blocks the datacenter ASN outright and that the only fix is an IP change. So the problem is real and measured for Reddit. It is not measured for the others.
+3. **A residential IP fixes IP-reputation blocks, not login walls.** Reddit public JSON endpoints work from a clean IP without login. X search, Instagram, LinkedIn, Facebook and TikTok mostly need a logged-in session. Donor nodes must NOT use the donor's cookies (privacy and liability), so those platforms stay mostly out of reach. X is limited to what is public (permalinks, oEmbed/syndication timelines). Promising "Reddit, X and all social media" would be a false claim. Phase 0 measures what actually works per platform before anything else is built.
+4. **Several "social" sources need no donors at all**: Hacker News (Algolia API), Bluesky (public AppView), Mastodon (public instance APIs), Lobsters, StackExchange, GitHub, dev.to, YouTube oEmbed/transcripts. They are cheap, reliable, and cover a large part of what developers want. Build these as direct adapters first (Phase 6A). Nodes are only for the platforms that block datacenter IPs (Reddit first).
+5. **Browser extensions cannot do TCP.** MV3 has no raw sockets. An extension can only run `fetch()`. So there are two fundamentally different transports, with different trust properties:
+   - **Tunnel mode** (native client): the server opens an end-to-end TLS session to the destination THROUGH the donor's TCP socket. The donor sees only ciphertext plus the destination host. The donor cannot read or tamper with content because they cannot forge the destination's certificate. Our `curl_cffi` Chrome fingerprint stays intact. This is the better mode.
+   - **Fetch mode** (extension): the donor's browser performs the HTTP request and returns the body. The donor sees the URL and plaintext response and CAN forge the response. Everything returned is untrusted and must be verified (section 5.6). TLS fingerprint is the donor's browser, which is fine.
+6. **A plain web page or service worker cannot do this at all.** The research table rates them "Low"/"Poor". The reality is "impossible": a page cannot `fetch()` reddit.com cross-origin (CORS), and cannot open raw sockets. Both are dropped from scope. Documented so nobody revisits them.
+7. **Open SOCKS5 is the wrong product.** The research recommends exposing a SOCKS5 listener. We do not need an open proxy. We need to reach a short, fixed list of public social domains for our own search. A destination-allowlisted exit (donor hard-refuses everything else) removes most of the abuse and liability surface the research file warns about (credential stuffing, ad fraud, illegal traffic). This is the single most important design decision and it is a clear rule, not a configurable maybe: **no open proxy, ever; allowlist enforced on server AND on the donor client.**
+8. **Existing seams to reuse, none to rebuild:**
+   - `stealth.stealth_async_client(proxy=...)` and `outbound_proxy_url`: a local node-backed forward proxy plugs into this with zero caller changes.
+   - `messaging/tickets.py` + `ws_tickets`: single-use WS auth ticket flow (browsers cannot set WS headers).
+   - `pubsub` lock-owner WS pattern (`4013` retry) for the node socket.
+   - `BaseService` + `ConfigField` for the dispatcher service and admin knobs.
+   - `LiveViewRelayService.VIEWS` + private `user.{uid}.*` pub/sub namespace for live donor stats.
+   - `user_consents` / `CONSENT_KINDS` for opt-in (default opted out is already how `ai_third_party` works).
+   - `utils.track_action` / `ACHIEVEMENTS` / `BADGE_CATALOG` for donor badges.
+   - `GatewayUsageLedger.record_external` pattern for metering consumers.
+   - `devii` `CONFIRM_REQUIRED`, `docs_api.endpoint()`, `DOCS_PAGES`, `audit` categories + `events.md`.
+9. **Legal and ToS exposure is real and is risk number one.** Reddit and X actively litigate and rate-limit scraping; ISPs restrict commercial use of residential lines; donors' IPs will get rate-limited or banned by the platforms. The plan includes a legal review gate (Phase 11) before any public launch. This is not legal advice and the plan does not assume the outcome.
+10. **Unknown that blocks scoping:** what the "new agent system on pravda.education" is and how it will call search. The plan gives it a stable internal interface (section 6) but its requirements (latency, volume, platforms) are open question Q3.
+
+## 1. Decisions needed from you before Phase 2 (everything else proceeds without them)
+
+| # | Decision | Recommendation | Why |
+|---|----------|----------------|-----|
+| D1 | Where does social search live: in devplacepy, or in the rsearch codebase? | devplacepy owns the node fabric and exposes an internal HTTP face; rsearch calls it (or devplacepy does the social search itself) | Nodes are tied to DevPlace accounts, consent, and the ledger. rsearch has no accounts. |
+| D2 | Native client language | **Go**, static binary, one file per OS/arch | Research recommends Go/Rust; zero runtime for Windows users. Adds a Go toolchain to the build. Alternative: Python zipapp (no new toolchain, but needs Python on the donor machine). |
+| D3 | Extension distribution | Sideloadable zip first (audience is developers), store submission later | Stores scrutinize proxy-like extensions; sideload ships sooner and the audience can handle it. |
+| D4 | Donation reward | XP + badges + leaderboard only. No coins, no money, no purchasable anything | Root rule: no payment path, no purchasable randomness. Keeps app-store conditionals untriggered. |
+| D5 | Minimum donor age | Adults only (`age_band` gate) | A minor must not share an IP/line. Needs a decision on how the existing `age_band` is read for legacy accounts with `NULL`. |
+| D6 | Is a data center or a cloud VPS allowed as a "donor"? | No: residential/mobile-ASN heuristic, admin override | The whole value is residential reputation. A VPS donor is just another datacenter IP. |
+
+## 2. Specification first (your rule 7: everything has a declared spec)
+
+Nothing else is written until the spec exists, because the server, the Go client, the extension, the docs and the tests all derive from it.
+
+1. `devplacepy/services/nodes/spec.py`: the single source of truth, as frozen dataclasses (`FrameSpec`, `LimitSpec`, `DestinationSpec`, `AdapterSpec`, `ProtocolSpec`). It declares:
+   - protocol version (integer, with `min_supported`),
+   - every frame type with its fields, direction, max size,
+   - every hard cap in section 3,
+   - the destination allowlist (domain suffix -> adapter -> allowed methods -> allowed ports -> rate limit),
+   - donor-side hard refusals (non-public IPs, ports other than 80/443, non-allowlisted hosts).
+2. `GET /nodes/spec.json` serves the spec so clients and tests read the same numbers. A contract test fails if the Go constants, the extension constants, the docs page, or the server drift from it.
+3. `devplacepy/templates/docs/nodes-protocol.html` (generated tables from the spec, not hand-copied) and `docs/nodes.html` (user-facing). Registered in `DOCS_PAGES`.
+4. A short `NODES.md` is NOT created; the nested `devplacepy/services/nodes/CLAUDE.md` is the engineering record, per repo convention.
+
+## 3. Hard caps and floors (nothing unbounded)
+
+All values below are starting ceilings, declared in `spec.py` and surfaced as `ConfigField`s only where an admin may lower them. Static ceilings, no autotuning.
+
+| Cap | Initial value | On hit |
+|-----|---------------|--------|
+| Devices per user | 5 | 409 with reason |
+| Connected nodes total (lock-owner worker) | 2000 | WS close `4029`, counter `nodes_rejected_capacity` |
+| WS frame size | 256 KiB | close `1009`, counter |
+| Response body per job | 2 MiB | truncate + flag `truncated=true`, never silently |
+| Concurrent jobs per node | 2 (donor may lower to 1) | scheduler skips node |
+| Per node, per destination domain | min 6 s between requests | scheduler skips node |
+| Global per destination domain | admin-set rps ceiling | queue, then 429 to caller |
+| Job timeout | 25 s | mark failed, count against node health |
+| Job queue depth | 500 | reject new with 429 + counter |
+| Caller wait | 15 s default, 60 s max | `FabricUnavailable` |
+| Per caller-owner daily fabric requests | admin-set (default 200 user, 0 guest) | 429, no donor load |
+| Donor daily bandwidth (donor-configurable) | default 500 MB, max 20 GB | node goes idle until reset |
+| Heartbeat | ping every 20 s, evict after 2 missed | reconnect |
+| Reconnect backoff | 1 s to 60 s, full jitter | n/a |
+| Ticket TTL | 30 s single use (existing) | n/a |
+| Result cache | 10 min TTL, 256 MiB total, 4 MiB per entry | LRU evict |
+| Usage daily buckets | keep 400 days, rolled into lifetime totals first | prune only after rollup verified |
+| Node event log | 30 days, 50k rows | prune |
+
+**Floors (machines hold, humans decide):**
+- The system may auto-**suspend** a misbehaving node (reversible, timed, e.g. circuit breaker after N consecutive failures or an integrity mismatch). It may never auto-**ban** a user or delete a ledger row. Hitting a ban threshold creates a flag for an admin and fires an admin notification.
+- Lifetime donation totals live on the donor row and are never decreased by pruning.
+- Protected destinations: the allowlist can only be changed by the primary admin and every change is audited.
+- A global kill switch (`nodes_enabled` site setting) disconnects every node within one tick. It is the first thing built in Phase 4 and tested first.
+
+## 4. Data model
+
+All tables ensured in `database/schema.py::init_db` (full column set, because `dataset` only creates the columns of the first insert), indexes with `CREATE INDEX IF NOT EXISTS`, every INSERT writes `deleted_at: None, deleted_by: None` where the table is soft-deletable. Helpers in a new `database/nodes.py`, exported through `database/__init__.py` like `skills.py`.
+
+| Table | Purpose | Soft delete? | Notes |
+|-------|---------|--------------|-------|
+| `node_devices` | one row per registered client install: `uid`, `user_uid`, `label`, `kind` (`native`/`extension`/`container`), `secret_hash`, `secret_prefix`, `platform`, `client_version`, `protocol_version`, `status` (`active`/`suspended`/`revoked`), `suspended_until`, `suspend_reason`, `country`, `asn`, `asn_class` (`residential`/`mobile`/`datacenter`/`unknown`), `ip_hash`, `last_seen_at`, `created_at` | yes (revoke = soft delete, cascade stamp) | index `(user_uid, deleted_at)`, `(status, last_seen_at)` |
+| `node_settings` | per-user donation prefs: `user_uid` (unique), `enabled`, `bandwidth_mb_day`, `max_concurrent`, `active_from`, `active_to`, `timezone`, `allowed_platforms` (JSON), `pause_on_battery`, `updated_at` | no (preference row) | enabled is subordinate to the consent, like `ai_correction_enabled` |
+| `node_usage_daily` | per `(device_uid, day)` counters: `requests_ok`, `requests_failed`, `bytes_up`, `bytes_down`, `cache_hits_served`, `integrity_failures` | no (derived, hard GC) | unique `(device_uid, day)`; upserted with one atomic `INSERT ... ON CONFLICT DO UPDATE SET col = col + excluded.col` (the `_add_usage` precedent) |
+| `node_donors` | lifetime totals per user: `user_uid` (unique), `requests_ok`, `bytes_total`, `first_donated_at`, `last_donated_at`, `xp_awarded_today`, `xp_day` | no (derived) | survives bucket pruning; this is what the profile card and leaderboard read |
+| `node_requests` | the cross-worker job queue: `uid`, `caller_kind`, `caller_id`, `url`, `method`, `adapter`, `mode` (`tunnel`/`fetch`/`any`), `status` (`queued`/`assigned`/`done`/`failed`/`expired`), `device_uid`, `result_status`, `result_bytes`, `result_body` (capped), `error`, `created_at`, `assigned_at`, `finished_at` | no (ephemeral, hard GC after 10 min) | partial index on `status IN ('queued','assigned')` |
+| `node_events` | operational log: connects, disconnects, suspensions, verification results, refusals | no (hard GC, 30 days) | feeds admin view, not audit |
+| `node_flags` | items needing a human: integrity mismatch bursts, datacenter-ASN donor, abuse reports against a node | yes | admin resolves; the floor rule's landing place |
+
+Related registrations (the repo fails the suite otherwise):
+- `database/moderation.py`: none of these carry user-generated content visible to others, so each goes in `UNREPORTABLE_TABLES` WITH its reason. `node_devices.label` is owner-only text; confirm it is never rendered to anyone else, or it becomes reportable.
+- `SOFT_DELETE_TABLES`: `node_devices`, `node_flags`.
+- `services/moderation/deletion.py::OWNED_TABLES`: add `node_devices`, `node_settings`, `node_donors` so account deletion cascades. Add `node_usage_daily` via the device join. Revoke live sockets in the same call.
+- `user_consents`: new `CONSENT_KINDS["bandwidth_sharing"]`. **Never granted by default, never backfilled.** A new consent is enforced at ONE choke point (section 5.3), never at N call sites.
+- Site settings seeded in `init_db` `operational_defaults`: `nodes_enabled` (default `0`), `nodes_max_total`, `nodes_daily_quota_user`, `nodes_daily_quota_guest`, `nodes_cache_ttl_seconds`, `nodes_social_via_nodes` (route hostile domains through nodes: default `0`).

+### 5.2 Routers (`devplacepy/routers/nodes/` package, mounted at `/nodes` in `main.py`)
+
+| Route | Auth | Purpose |
+|-------|------|---------|
+| `GET /nodes/spec.json` | public | protocol spec for clients and tests |
+| `GET /nodes/client-version` | public | latest client versions, `min_protocol`, sha256 per artifact |
+| `GET /nodes/download/{artifact}` | public | native binaries, extension zip, systemd unit, container compose (static files from `DATA_DIR/node_clients/`, sha256 listed) |
+| `POST /nodes/devices` | `require_user` + consent | create device, returns the secret ONCE |
+| `POST /nodes/devices/{uid}/rotate` | owner | new secret, old revoked immediately |
+| `POST /nodes/devices/{uid}/delete` | owner or admin | soft delete + kick socket |
+| `POST /nodes/ticket` | device secret | exchange secret for a 30 s single-use WS ticket |
+| `WS /nodes/ws` | ticket | the node socket; lock-owner gated, `4013` fast retry like `/pubsub/ws` |
+| `POST /nodes/internal/fetch` | admin / API key, service accounts | the HTTP face of `NodeFabric.fetch` for agent systems |
+| `GET /nodes/stats` | public | aggregate only: total donated bytes, requests, active donors (no per-user data) |
+| `GET /nodes/leaderboard` | public | top donors, opt-in display |
+| `POST /profile/{username}/donation` | owner | settings (bandwidth, hours, platforms) |
+| `GET /admin/nodes`, `POST /admin/nodes/...` | admin | pool health, flags, suspend/unsuspend, allowlist, kill switch |
+
+Rules from the repo applied to every route: `respond(request, template, ctx, model=XOut)` for the HTML+JSON faces, `*Out` schemas in `schemas/nodes.py` (a context key missing from `XOut` is silently dropped from JSON), Pydantic `Form` models in `models.py`, `RedirectResponse(..., status_code=302)` literal, no `respond()` ctx key colliding with a Jinja global (use `viewer_is_admin`), specific paths before catch-alls, `is_senior_admin` on every per-user admin mutation, delete = owner OR admin.
+
+### 5.3 The consent choke point (`ConsentGate`)
+
+One function, `ConsentGate.allows(user_uid) -> Verdict(reason)`, true only when ALL of: `bandwidth_sharing` consent granted and not withdrawn, account active (not suspended, not in deletion grace), adult `age_band` (D5), `node_settings.enabled`, global `nodes_enabled`. It is called in exactly three places:
+1. `POST /nodes/devices` and `POST /nodes/ticket` (refuse to mint).
+2. `WS /nodes/ws` accept (refuse to connect).
+3. `NodeScheduler.eligible()` (a node whose owner stopped qualifying is never assigned work, and `NodeRegistry` kicks the socket on the next tick).
+
+Withdrawing the consent takes effect within one dispatcher tick, not at next reconnect. Consent change is owner-only, exactly like `routers/profile/consent.py` (reuse `_owner_only`). **Devii may read status and may withdraw, but must not be able to grant** (a chat agent granting a bandwidth-sharing consent is not a consent). Verify how the existing `set_consent` Devii tool treats grants and restrict this kind there.
+
+### 5.4 WebSocket and multi-worker model
+
+- `/nodes/ws` is gated to the service-lock owner worker with the `4013` fast-retry close, so all node sockets converge on one process (precedent: `/pubsub/ws`, `/devii/ws`). This keeps `NodeRegistry` a single in-memory truth. Trade-off, stated: one worker carries all sockets, hence the 2000 cap, and a crash drops every node for a few seconds until they reconnect. Acceptable because reconnect is built in.
+- Callers on ANY worker enqueue into `node_requests` (DB). The lock-owner `NodeDispatcher` ticks fast while at least one node is connected and a request is queued (target 200 ms, indexed partial query; the cost is measured in Phase 0, not assumed), assigns, and writes the result back. Callers `await` by short-sleep polling the row. A same-process fast path skips the table when the caller is already on the owner. This is the `JobService` philosophy (DB-backed, durable enough, no inter-worker RPC) with a tighter tick.
+- Large bodies never go through SQLite long term: `result_body` is capped (2 MiB) and hard-GC'd after 10 minutes; the durable copy is the `ResultCache` entry, bounded in bytes.
+- nginx: add an upgrade `location = /nodes/ws` to `nginx/nginx.conf.template` (the catch-all `location /` strips upgrade headers, and the file already has one per WS route). **Also verify on the `devplace.net` front host**, whose own proxy and SSH tunnel have separate idle timeouts; test both hostnames per the production-diagnosis procedure, never with `--resolve`.
+
+### 5.5 Frame protocol (summary; the authoritative version is `spec.py`)
+
+Client to server: `hello{protocol, client_version, kind, platform, caps, limits}`, `pong`, `job_result{job_id, status, headers, body_b64, truncated, timings}`, `job_error{job_id, code}`, `tunnel_data{conn_id, b64}`, `tunnel_close{conn_id}`, `usage{bytes_up, bytes_down}`.
+Server to client: `welcome{device_uid, limits, allowlist_version, settings}`, `ping`, `job{job_id, method, url, headers, timeout}`, `tunnel_open{conn_id, host, port}`, `tunnel_data`, `tunnel_close`, `settings_update`, `kick{reason}`.
+Every frame is validated against the spec on both ends. An unknown type or an oversize frame closes the socket with a loud reason and a counter (never silently ignored).
+
+### 5.6 Trust, verification and integrity
+
+Fetch-mode donors can forge content, and forged content flows into search results and into the AI agent. Controls, in order of strength:
+1. **Prefer tunnel mode** whenever a tunnel-capable node is available: TLS makes tampering impossible. Fetch mode is only used for extension donors.
+2. **Never trust fetch-mode bodies without checks**: structural validation by the adapter (must parse as the platform's JSON/HTML shape), size sanity, and **sampled redundancy**: a configured fraction of fetch-mode jobs (plus 100 % for a node's first N jobs) are also fetched through a second independent node or directly; a content-hash or structural mismatch increments `integrity_failures`, suspends the node, and writes a `node_flags` row.
+3. **Provenance on every result**: results carry `via=tunnel|fetch|direct` and the agent/search layer can down-weight or label fetch-mode content.
+4. **Canary / liveness proof**: on connect, the verifier makes the node fetch `GET /nodes/canary/{nonce}` (served by us, records the observed source IP). Proves egress really goes out of the donor's own line, detects a node that is itself behind another proxy, and lets us compare the observed IP with the WS peer IP.
+5. **ASN class**: classify residential/mobile/datacenter via an offline ASN database file under `DATA_DIR` (no third-party lookup, so no donor IP leaves our server). Datacenter donors get `asn_class=datacenter` and are excluded from the pool by default (D6) with a flag for an admin.
+6. Donor client strips cookies and auth: extension uses `credentials: "omit"` and never attaches the donor's session; native client sends only the headers the server specified.
+
+### 5.7 Donor-side safety is enforced on the donor, not only on the server
+
+A compromised or buggy server must not be able to point a donor's machine at their LAN. The clients enforce, independent of any server frame:
+- allowlisted hosts only (list baked in per release and refreshed from the server, where a refreshed list can only be equal or narrower than the baked-in superset),
+- ports 80 and 443 only,
+- resolve DNS locally, refuse private/loopback/link-local/CGNAT/multicast addresses, then connect to the resolved IP (defeats DNS rebinding),
+- no redirects to a non-allowlisted host,
+- the donor's configured bandwidth, concurrency and schedule caps, applied locally even if the server sends larger ones.
+
+## 6. Consumers: how search gets the data
+
+`NodeFabric` is the only thing consumers import:
+
+```
+NodeFabric.fetch(url, *, owner, mode="any", cache=True, timeout=...) -> FabricResult
+NodeFabric.social_search(query, *, platforms, owner, limit) -> list[SocialHit]
+NodeFabric.available() -> FabricStatus   # nodes online, per-platform health
+```
+
+Resolution order (each step loud when it fails, never silent):
+1. `ResultCache` hit.
+2. **Direct adapters** for platforms that need no donors (Hacker News, Bluesky, Mastodon, Lobsters, StackExchange, GitHub, dev.to).
+3. **Nodes** for allowlisted blocked platforms (Reddit first), tunnel mode preferred.
+4. Configured `outbound_proxy_url` if the admin has one.
+5. rsearch (existing, includes its own Jina fallback).
+6. `FabricUnavailable` with a reason code; the caller reports "social results unavailable", never invents any.
+
+Integration points, one commit each:
+- `services/jobs/deepsearch/crawl.py`: `search_queries` gains a social bucket merged by the existing `_interleave`; `HOSTILE_DOMAINS` stops being a static skip list and becomes `fabric.can_serve(url)`: a hostile URL is skipped only when the fabric cannot serve it. `fetch_page` routes those URLs through `NodeFabric.fetch`. The `rsearch` NDJSON ledger frame gets a sibling `fabric` frame so `DeepsearchService._run_worker` meters it like `record_external`.
+- Devii: tools `social_search`, `fetch_social_page` (`requires_auth=True`, metered, guests refused), plus owner tools `node_status`, `node_settings_get`, `node_settings_set`, `node_device_list`, `node_device_revoke` (`CONFIRM_REQUIRED` + declared `confirm` param, per the rule). Update `SYSTEM_PROMPT` so the model prefers platform data, then `social_search` only when asked about outside discussion, and never claims a platform it cannot reach.
+- `POST /nodes/internal/fetch`: the stable interface for the pravda.education agent system and any external caller. Auth: API key / Bearer, rate-limited, per-owner daily quota, documented.
+- Cost and fairness: every fabric call is metered into a `fabric_usage` view per caller (requests, bytes, cache hit ratio) so a single caller cannot drain the donor pool; caller quota is checked before any donor is touched.
+
+## 7. Clients
+
+All clients speak the same protocol from `spec.json`. Conformance is tested against the Python reference client (Phase 10), not by eyeballing.
+
+### 7.1 Native node (D2: Go)
+- Single static binary, linux/amd64, linux/arm64, darwin/arm64, darwin/amd64, windows/amd64. Tunnel mode (TCP relay) and fetch mode.
+- Config file + flags; `devplace-node login` takes the one-time device secret; `devplace-node status`; `devplace-node run`.
+- Reconnect with full-jitter backoff, 20 s ping, local bandwidth/schedule/concurrency enforcement, battery-aware pause on laptops, quiet by default, structured log with a per-day totals line.
+- Packaging: systemd **user** unit (`loginctl enable-linger` documented), Windows Service/scheduled task, macOS LaunchAgent, and a Docker/Podman compose snippet (the repo already ships `docker-compose.podman.yml`, so container users are a known audience).
+- Built reproducibly from a `nodes/client/` directory with a `make node-client` target; artifacts + sha256 land in `DATA_DIR/node_clients/`; the version manifest is generated, not hand-written.
+
+### 7.2 Browser extension (MV3, Chrome + Firefox)
+- Fetch mode only. Service worker holds the WS; 20 s keepalive ping plus a `chrome.alarms` reconnect backstop; state in `chrome.storage.session`.
+- `fetch()` with `credentials: "omit"`, header rewriting via `declarativeNetRequest` for the headers the spec allows, allowlist enforced before every request, response size cap.
+- Honest, prominent disclosure on first run: what is shared, what is not, the on/off switch, live counters.
+- Distribution per D3.
+
+### 7.3 Later (explicitly out of this plan's first release)
+Tauri tray app, signed auto-updates, mobile. Mobile stays out: iOS forbids the background behaviour and Android is restricted, as the research notes.
+
+## 8. Frontend
+
+Rules: responsive down to small phones (a wide button group becomes a dropdown), ES6 modules one class per file instantiated on `app`, tokens only in CSS, no literals, no `var()` fallbacks, `static_url`/`assetUrl` for assets, dates via `local_dt`, no `data-render` on server content, presence/pubsub via the existing managers.
+
+1. **Profile tab "Donate"** (owner-only; others see only a donor badge and lifetime totals):
+   - plain-language explainer first ("What you share, what you never share"), the consent toggle second, everything else only after consent. Product stays simple for the member: one switch, three sliders, a download card.
+   - bandwidth per day, concurrent connections, active hours, platform checkboxes, pause-on-battery.
+   - devices list with last seen, country/ASN class, bytes today, rotate and remove.
+   - **"Donated by you" card**: requests served, data transferred (up/down), first/last donated, this month vs lifetime. Server-counted only.
+   - download card: per-OS choice rendered as a dropdown on narrow screens, checksums shown, copy-paste install lines (systemd, docker), extension zip.
+   - live numbers via a private pub/sub topic `user.{uid}.nodes` published by the lock-owner relay (add one row to `LiveViewRelayService.VIEWS`, re-checking the owner in the compute callable like the workspace topic), with a 30 s HTTP fallback poll.
+2. Files: template `templates/_node_donation.html` partial included by `profile.html`; `static/js/NodeDonation.js` (`app.nodeDonation`); CSS `static/css/nodes.css` using existing tokens; reuse `Http`, `Poller`, `Tabs.js`, `dp-dialog` for confirmations.
+3. **Public surfaces**: landing/footer line "The community has donated X GB across Y requests" from `GET /nodes/stats` (aggregate only), a `Top donors` section on the leaderboard (opt-in display), donor badge via `_award_badge.html` / `Avatar.badgeElement` reuse.
+4. Admin: `/admin/nodes` (templates `admin_nodes.html`): pool size by country/ASN class, per-platform success rate, queue depth, flags, suspend/unsuspend, caps, allowlist, kill switch; live via `admin.nodes` topic row in `VIEWS`; `ServiceMonitor` already covers the service tab.
+
+## 9. Gamification, incentives and anti-fraud
+
+- `ACHIEVEMENTS`: `node.first_donation`, `node.1gb`, `node.10gb`, `node.100gb`, `node.30_days`, in `BADGE_CATALOG` group "Community".
+- XP is awarded only for server-verified successful jobs, with a hard daily XP cap per donor (`node_donors.xp_awarded_today`), so synthetic traffic cannot farm progression. Through `award_rewards` only (never wrapped in `background.submit`).
+- Counters are written server-side from what the server actually relayed; the donor's self-reported `usage` frame is advisory and is compared, never trusted.
+- Self-dealing guard: a donor's own account cannot be the caller whose jobs are assigned to that donor's nodes for reward purposes.
+- No money, no coins, no random rewards (D4).
+
+## 10. Audit, privacy, safety, compliance
+
+1. **Audit events** (`events.md` + `category_for` + recorder at the mutation point, via the `audit-event` skill): `node.consent.grant`, `node.consent.withdraw`, `node.device.create`, `node.device.rotate`, `node.device.delete`, `node.settings.update`, `node.suspend`, `node.unsuspend`, `node.flag.resolve`, `node.allowlist.update`, `node.killswitch`. Connects/disconnects/jobs are metrics and `node_events`, not audit rows (volume).
+2. **Privacy (this is a new category of personal data plus a third-party disclosure, so it ships WITH the feature)**: update `templates/docs/privacy.html` and the app-store privacy declarations. State: IP address and approximate location are processed; only a salted hash and coarse country/ASN class are stored; retention periods for `node_events`/hashes; what the donor can see (destination host, and in fetch mode the URL and body); that the platform's content passes through the donor machine; the explicit statement that the donor's cookies and accounts are never used. Plain-English donor terms page, ISP-terms warning, consent text, and a visible off switch.
+3. **App-store conditionals** (root rule): no payment path, no purchasable randomness, no cross-app tracking introduced. Hide the donate UI inside any app-store shell build. Verify against current store policy before submission rather than assuming.
+4. **Abuse response**: report a node/destination path, admin suspend within one tick, allowlist narrowing, per-destination circuit breaker, the kill switch, and a documented contact. Because the allowlist is destination-restricted there is no path for credential stuffing, ad fraud or arbitrary traffic through a donor.
+5. **Maturity/moderation**: fetched third-party content is untrusted. It goes through `render_content` (server) or `DOMPurify` (client) like everything else and through the existing content filter when it is persisted anywhere. Fabric results are never rendered as raw HTML.
+
+## 11. Phased delivery
+
+Each phase ends with: clean import, per-language checks, em-dash scan (character and entity), `pyflakes`/`ruff` on touched files, the four-layer verification where listed, the full `make test` (all three tiers), then commit (hook auto-bumps the version), deploy with `make docker-reload`, and verification live on both hostnames. A change that is not running is not done.
+
+**Phase 0: Measure before building (no production code).** Scratch scripts against temp DB only.
+- Real-machine experiment: a prototype WS relay (use `pywssocks` / the `residential-proxy-aggregator` design as reference) with one residential node and one datacenter node. Measure Reddit `.json` and `old.reddit.com` success rate per IP class, rate-limit thresholds per IP, X permalink/oEmbed/syndication behaviour without login, Instagram/LinkedIn/Facebook/TikTok reality. Output: a measured per-platform viability table committed to the plan. Claims without a number stay labelled "unmeasured".
+- Tunnel-mode feasibility: confirm `curl_cffi` through an HTTP-CONNECT bridge preserves the Chrome fingerprint end to end and that the cleartext-HTTP/2 gotcha in the repo does not apply (https only).
+- Capacity: simulated-node harness (our own, outside `locust`) for 100/500/2000 sockets on one worker: memory, CPU, frame latency, dispatcher tick cost against SQLite. These numbers set or replace the caps in section 3.
+- Reconnect/idle behaviour through BOTH edges: `pravda.education` (molohttp) and `devplace.net` (front host + SSH tunnel). Measure the actual idle timeout of each.
+- Exit criteria: D1, D2, D3, D5, D6 decided; viability table written; caps confirmed or changed.
+
+**Phase 1: Specification and contracts.** `spec.py`, `/nodes/spec.json`, docs protocol page skeleton, contract-test scaffolding in `tests/unit/services/nodes/`.
+
+**Phase 2: Data layer.** Tables, indexes, helpers in `database/nodes.py`, `CONSENT_KINDS` entry, `OWNED_TABLES`, `UNREPORTABLE_TABLES` with reasons, soft-delete registrations, settings seeds, `UsageLedger` with atomic upserts. Four-layer verification applies here (counters + daily caps are a spendable resource): property checks on cap arithmetic, stateful fuzz of increment/rollup/prune with invariants (totals never decrease, daily never exceeds cap), real multi-process race on the daily-cap `UPDATE ... WHERE` using `COALESCE(col, 0)` and a freshly-created unset row (not pre-zeroed).
+
+**Phase 3: Registry, session, consent gate, kill switch.** `NodeRegistry`, `NodeSession`, `frames.py`, `ConsentGate`, `nodes_enabled` kill switch (built and tested first). Routers for devices/ticket/WS handshake only. No job traffic yet. nginx upgrade location. Reuse of the ticket mechanism by adding a `scope` column to `ws_tickets` (default `messages`) instead of a parallel table.
+
+**Phase 4: Broker, scheduler, dispatcher, policy, circuit breakers, cache.** Job lifecycle `queued -> assigned -> done|failed|expired`, fairness, per-domain limits, queue cap with 429. Four-layer verification: property tests on scheduler fairness and cap enforcement; stateful fuzz of connect/disconnect/assign/complete/expire with invariants (a job is assigned to at most one node, a node never exceeds its concurrency, a withdrawn consent is never assigned work); real-process concurrency test of two dispatchers racing one slot (must be impossible by construction, since only the lock owner dispatches, and proven anyway).
+
+**Phase 5: Python reference client + test harness.** A small reference node used by the api/e2e tests and as the protocol conformance oracle. Includes fault injection: dropped frames, slow nodes, oversize bodies, forged bodies, DNS-rebinding attempt, private-IP target.
+
+**Phase 6A: Direct adapters** (no donors): Hacker News, Bluesky, Mastodon, Lobsters, StackExchange, GitHub, dev.to into `NodeFabric.social_search`, DeepSearch and the Devii tools. This ships user value before any donor exists.
+**Phase 6B: Node-backed adapters**: Reddit first (per the Phase 0 table), then each additional platform only if Phase 0 measured it viable. `NodeVerifier` redundancy sampling for fetch mode.
+
+**Phase 7: Native client (Go) + packaging** (systemd user unit, launchd, Windows service, compose). Cross-compile target, checksums, version manifest, conformance run against the reference oracle.
+
+**Phase 8: Browser extension.** MV3 Chrome + Firefox build, disclosure screen, keepalive/alarms, conformance run, sideload zip served from `/nodes/download`.
+
+**Phase 9: Frontend and admin.** Profile Donate tab, donated-by-you card, devices, downloads, live topic, leaderboard section, landing stat, `/admin/nodes`. Screenshot-verify with the `screenshot` skill at phone and desktop widths.
+
+**Phase 10: Devii, docs, SEO, CLI.**
+- Devii actions in `actions/catalog/nodes.py` (owner tools above), dispatcher/registry wiring, `CONFIRM_REQUIRED` for revoke, `requires_auth` matched to route guards, tool-group registration so the admin tool-prefs UI lists them.
+- `docs_api/groups/nodes.py` `endpoint()` entries with `sample_response`; `DOCS_PAGES` for `nodes.html` and `nodes-protocol.html`; role-gating correct (protocol page admin/developer tier).
+- SEO: Donate tab `noindex`; any public stats page indexable and in the sitemap.
+- CLI: `devplace nodes list|stats|suspend|unsuspend|prune|clear`, destructive commands support `--dry-run` per the existing `accounts prune` convention (flag the conflict with the global dry-run-by-default rule to you if you want the default flipped; consistency with the existing CLI is the project rule).
+- README, `devplacepy/services/nodes/CLAUDE.md`, a row in the root `CLAUDE.md` Subsystem map (a genuinely new architectural area), `locustfile.py` untouched for the WS (locust-maintainer: the node socket is deliberately excluded and the HTTP read routes get weighted tasks).
+
+**Phase 11: Hardening and launch gate.**
+- Legal review gate: platform ToS exposure per platform, donor terms, ISP warning text, jurisdiction. Launch is blocked on a recorded decision.
+- Load and soak: 24 h soak with simulated nodes, reconnect storms (all sockets drop at once, then return), full-disk and DB-lock behaviour, worker restart mid-job. Numbers replace assumptions in `CLAUDE.md`.
+- Security-maintainer pass (allowlist bypass, SSRF on the server's own fetch path, ticket replay, device secret leakage, admin seniority on node moderation).
+- Full maintenance fleet (`fleet` skill): audit, background, devii, docs, dry, fanout, frontend, locust, security, seo, style, test dimensions.
+- Rollout: `nodes_enabled=0` by default. Stage 1: your own machines only (including a residential line) for a week, measuring success rate, latency, donor-side CPU and bandwidth. Stage 2: invite-only developers. Stage 3: open, still behind per-caller quotas. The kill switch stays one click away.
+
+**Phase 12: Documentation of record.** `devplacepy/services/nodes/CLAUDE.md` states what the system does today, with gaps listed next to the code that will close them (no roadmap cosplay). Measured numbers only, each labelled with the machine it came from.
+
+## 12. Test plan (by tier, mirroring the path)
+
+- `tests/unit/services/nodes/`: spec invariants and contract (docs, clients, server agree), frame codec, `DestinationPolicy` (allowlist, ports, private IPs, redirects, DNS rebinding), scheduler (fairness, per-domain interval, concurrency, bandwidth caps), circuit breaker, cache bounds and LRU, ledger math, ASN classification, XP daily cap, adapters (parse recorded fixtures, malformed input, forged-structure rejection).
+- `tests/api/nodes/` (mirror the URL path): consent gating on every entry point, device create/rotate/revoke, secret shown once, ticket single-use and expiry, WS handshake with the reference client, full job round trip, withdrawal kicks the socket within a tick, kill switch, daily quotas, 429 paths, account deletion cascade, JSON and HTML faces for every route, admin seniority, `/nodes/stats` leaks no per-user data, `/nodes/internal/fetch` auth.
+- `tests/e2e/profile/` (Playwright, `wait_until="domcontentloaded"`): enable flow with consent, device creation and one-time secret, settings persistence, live counter update, withdraw flow, responsive layout at phone width, owner-only visibility. Any test flipping a global setting restores it in `try/finally`.
+- Rigorous verification scripts (disposable, temp DB via `DEVPLACE_DATABASE_URL`/`DEVPLACE_DATA_DIR`, never `data/`): the four layers from root `CLAUDE.md` for the ledger, scheduler and job state machine.
+- The test hook that guards the production DB applies: no test or script touches `data/devplace.db`.
+
+## 13. Risks, stated plainly
+
+| Risk | Likelihood | Mitigation | Residual |
+|------|-----------|------------|----------|
+| Platform ToS/legal action against scraping | real | allowlist, legal gate, per-domain rate limits, kill switch | cannot be engineered away |
+| Donors' IPs get rate-limited or banned by platforms | high on Reddit | per-donor-per-domain caps, caching, consent text says so | some donors will be unhappy; transparent counters help |
+| X/Instagram/LinkedIn/TikTok unreachable (login walls) | high | Phase 0 measures; promise only what is measured | those platforms stay limited |
+| Fetch-mode donor forges content | possible | tunnel preferred, structural validation, sampled redundancy, provenance labels, suspension | extension donors are lower trust, labelled as such |
+| Small donor pool means flaky results | high at launch | cache, fallback chain, honest "unavailable" | search stays at today's quality, not worse |
+| Single worker holds all sockets | by design | cap, fast reconnect, measured capacity | brief drop on worker crash |
+| Donor privacy incident | low-impact by design | no cookies, hashed IP, destination allowlist, docs | disclosure must stay accurate |
+| Scope creep into an open proxy | tempting | the "no open proxy" rule is in `spec.py` and the contract test | needs reviewer discipline |
+
+## 14. Open questions for you
+
+- Q1: Confirm D1 to D6 above (a one-line answer each is enough).
+- Q2: Is there any residential line you control for the Phase 0 measurement, or do we recruit three donors for it?
+- Q3: What does the pravda.education agent system need from search (volume, latency, which platforms, guest access)? It sets the daily quotas and the `/nodes/internal/fetch` contract.
+- Q4: Should donor identity be public (leaderboard, badge) by default or opt-in? The plan assumes opt-in display.
+- Q5: Who owns the legal review, and is a launch without it acceptable for the invite-only stage?

+# Quality Project Playbook: What Belongs in AGENTS.md
+
+Generic companion to `quality_software.md` and `quality_versioning.md`.
+It defines what an agent instruction file must contain so that every
+agent (and every human) develops the same way and the project stays
+consistent and current.
+
+Naming note: this repo uses `CLAUDE.md` instead of `AGENTS.md`, but
+the system is what matters, not the filename. Three layers, loaded
+by scope:
+
+- Personal base rules (DevPlace: `~/.claude/CLAUDE.md`). Applies to
+  every project for one operator: safety, proof, craft, ops habits.
+- Root project file (DevPlace: `CLAUDE.md`, ~440 lines). Applies to
+  the whole repo regardless of area touched. Always loaded, so it
+  stays proportional to global rules only.
+- Nested subsystem files (DevPlace: ~30 `CLAUDE.md` files next to
+  the code). Loaded only when a file under that directory is read
+  or edited. Deep mechanics, helpers, pitfalls, worked examples.
+
+If your tooling reads `AGENTS.md`, use that name with the identical
+three-layer split. Never merge all three into one file: the root
+would bloat past usefulness and agents would stop reading it.
+
+## 1. Personal base rules (cross-project, rarely changes)
+
+One short file per operator, ported across projects. Contents:
+
+- Control over cleverness: hard caps on everything unbounded,
+  floors automated processes may never cross, static ceilings over
+  autotuning, fewer dependencies.
+- Safety: destructive ops dry-run by default and explicitly
+  confirmed, loud skips over silent corruption, verify-before-write,
+  deletes that reclaim (compaction in the same change).
+- Proof: measured claims only, real-path testing with failure
+  injection, suite after behavior change, live verification after
+  deploy.
+- Craft: exact minimal diffs, boring technology, research before
+  load-bearing decisions, docs describing today with gaps marked.
+- Communication: direct and factual, disagree with data, fixed
+  style bans (DevPlace: no em dashes anywhere).
+- Operations: commit, deploy, verify in the same session;
+  retention and checks run inside the system on loops.
+
+This layer never names project paths or stack details. When it
+conflicts with a project file, the project file wins.
+
+## 2. Root project file (global rules, always loaded)
+
+Ordered contents, each earning its place by applying to every area:
+
+1. Project identity in one paragraph: what it is, stack in one
+   line per layer, ports, key constraints (username rules,
+   password rules, data layout). An agent must orient in 30 seconds.
+2. Commands table: install, dev, prod, every test target, load
+   test, lint, clean. Exact commands, no prose alternatives. Which
+   interpreter each target uses.
+3. Single-test invocation and the failure-triage order
+   (cheapest-first), so agents debug efficiently instead of
+   re-running the slowest suite.
+4. CLI reference for management commands (one line each), so agents
+   use named commands instead of inventing shell one-liners.
+5. Runtime data layout: the single data root, the path registry,
+   and the rule that no module computes a path from scratch.
+6. Environment variables table: name, default, purpose. Complete;
+   an undocumented env var is a trap.
+7. Subsystem map: table of every nested doc with one-line scope, so
+   agents know which file to load (and that it exists).
+8. Architecture: request pipeline, routing layout, templates and
+   frontend rules, content pipeline, auth, database, background
+   work. One paragraph each with pointers down, not full detail.
+9. Hard rules, each marked as such: soft delete, reportability,
+   production-DB protection, confirmation gates, changelog/doc
+   duties. A hard rule states the rule, the mechanism enforcing it,
+   and what fails if violated (usually a named test).
+10. Conventions: naming, validation style, response style,
+    ownership checks, date formats, slug/ID handling, role storage.
+    Each convention shows the one correct shape.
+11. Testing: tier definitions, directory mirroring rule, fixture
+    stack, required patterns, full-suite gate. Pitfalls live in the
+    nested test doc; the root states the gate.
+12. Feature workflow: the ordered step list (understand, data,
+    server, view, safety, agent+docs, document, validate) with the
+    blocking rule: a failed step blocks the rest.
+13. CI/CD: what runs on push/PR, merge gate, DTAP stages, deploy
+    then verify.
+
+Size guard: if the root passes ~500 lines, detail has leaked in
+that belongs in a nested file. Split it out.
+
+## 3. Nested subsystem files (deep detail, loaded on touch)
+
+One per directory that owns a mechanic (DevPlace: routers,
+services, database, static/js, static/css, templates, tests).
+Contents:
+
+- Scope line: which paths it covers, in the first line.
+- The mechanic: helpers, entrypoints, and patterns with exact
+  symbol names (`conditional_update_farm`, `respond()`,
+  `get_users_by_uids`), never paraphrased APIs.
+- The closed sets: registries, token scales, breakpoint lists,
+  event catalogues. An agent must be able to check membership.
+- CORRECT/WRONG pairs for the two or three mistakes every newcomer
+  makes (DevPlace tests doc: scoped vs unscoped selectors, waits
+  vs sleeps). Show code, not advice.
+- Common pitfalls section: the real bugs this area produced, each
+  with cause and fix. Pitfalls are bug reports that pay rent.
+- Worked examples: one end-to-end change with the file count it
+  touched, so agents calibrate "one feature = N files".
+- Backwards-compatibility notes where the area promises them
+  (what may never break, what the migration path is).
+
+A nested file never repeats the root. It assumes the root was read
+and only adds what the root deliberately omitted.
+
+## 4. Severity levels: hard rule, convention, guidance
+
+Agents follow what they can rank. Mark every statement:
+
+- Hard rule: enforced by code, hook, or failing test. Violation
+  breaks the suite or is denied by tooling. Example: every removal
+  is a soft delete; production DB access needs written confirmation
+  plus a token; new user-visible tables must be classified
+  reportable or private with a reason.
+- Convention: one correct shape, enforced by review. Example:
+  response helpers, date formats, commit message shape, no second
+  implementation of an existing helper.
+- Guidance: preferred approach with stated tradeoffs. Example:
+  boring technology, static ceilings over autotuning, research
+  before load-bearing decisions.
+
+Write the enforcement next to the rule ("fails in
+`tests/unit/database/moderation.py`", "denied by the pre-tool hook").
+A rule without a named enforcer is a wish.
+
+## 5. Keeping the docs updated (the docs are code)
+
+- Same-change rule: the doc update ships in the commit that changes
+  the behavior. Docs describing yesterday are worse than missing
+  docs because agents trust them.
+- Landing rule: new global rule goes to the root, new mechanic or
+  pitfall to the nested file, new user-visible behavior to README
+  plus the user docs site. The feature workflow names this step so
+  it is never skipped.
+- Measured, not remembered: counts, diagrams, and claims derive
+  from the running app and schema (DevPlace architecture atlas is
+  generated from the imported app object and live schema, and
+  records where docs and code disagree).
+- No fiction: docs state what the system does today, gaps listed
+  next to the code that will close them. No roadmap prose, no
+  aspirational architecture.
+- Versioned per `quality_versioning.md` section 4: header comment,
+  history table, bump in the same commit. All three layers count as
+  markdown and follow the scheme.
+- Deletion duty: removing a feature removes its doc lines in the
+  same commit. Stale sections are found by searching for the
+  removed symbol, not by rereading.
+
+## 6. Anti-patterns: what does NOT belong
+
+- Tutorial prose or onboarding narrative. Agent docs are reference,
+  not a course. One example per pattern, then the rule.
+- Duplicated detail in two layers. If root and nested both explain
+  it, one will rot. Root states the rule and points down.
+- Unbounded lists ("all endpoints", "all settings") pasted by hand.
+  Point at the registry, the table, or the command that lists them.
+- Aspirational rules nobody enforces. Each release, delete one rule
+  the suite does not check and no review ever cites.
+- Secrets, credentials, customer data, or production hostnames.
+  Env var names yes, values never.
+- Style debates or option-weighing. Decide with an opinion, state
+  the tradeoff in one line, move on.
+
+## 7. Replication checklist for your hosting site
+
+1. Personal base file: safety, proof, craft, ops. Shared across
+   your projects, project file wins on conflict.
+2. Root `AGENTS.md`: identity, commands, triage order, CLI, data
+   layout, env table, subsystem map, architecture pointers, hard
+   rules with enforcers, conventions, testing gate, workflow, CI/CD.
+   Under ~500 lines.
+3. Nested files per area: `billing/`, `provisioning/`,
+   `support/`, `status/`, plus `tests/` pitfalls and
+   `templates/` partials. Scope line first, symbols exact,
+   CORRECT/WRONG pairs, pitfalls from real bugs.
+4. Severity marks on every statement plus the named enforcement
+   (test path, hook name, review gate).
+5. Same-change doc updates, landing rule, measured claims, no
+   fiction, version headers on all three layers, deletion duty.
+6. Quarterly audit: run the suite, grep each hard rule for its
+   enforcer, delete one unenforced rule, regenerate the
+   architecture counts.

+# Quality Software Playbook: How to Build a Site as Good as DevPlace
+
+This is a generic, reusable method distilled from how DevPlace was built.
+It is written so you can apply it to a completely different site, for
+example a hosting company (accounts, products, orders, provisioning,
+support tickets, status pages), and get the same stability and quality.
+
+It is not about copying features. It is about copying structure,
+constraints, and verification habits.
+
+## 1. Core philosophy
+
+1. Boring technology, smart edges. One backend language, one database
+   file, server-rendered HTML, plain JavaScript. Put complexity where
+   you can see it (request handlers, templates), keep storage dumb.
+2. Fewer moving parts. Every dependency is a way to fail. Prefer the
+   standard library, one process type, one data root.
+3. Server-rendered first. The page works without JavaScript. JavaScript
+   only upgrades live behavior (polling, websockets, optimistic UI).
+4. One data source, many faces. Every domain object is served as HTML
+   for browsers, JSON for API clients, an agent/tool action for
+   automation, and a documented endpoint. Design the data once, then
+   expose all four.
+5. Exact, minimal diffs. Edit existing files, reuse existing helpers,
+   match existing visual structure. Zero tolerance for a second way
+   of doing something that already has one way.
+6. Measure, do not theorize. Performance claims come from runs on real
+   machines. If there is no measurement, say so.
+7. Loud skips beat silent corruption. Reject unverifiable input with a
+   clear reason and a counter. Never store what you cannot vouch for.
+
+Hosting example: a VPS order is one row in one table. The same handler
+renders the order page (HTML), returns the order (JSON), exposes a
+`order_create` automation action, and is documented in your API docs.
+
+## 2. Reference stack (proven shape)
+
+You can swap brands, but keep the shape:
+
+- Backend: one typed web framework (DevPlace: Python + FastAPI).
+- Templates: server-side templates with one shared instance
+  (DevPlace: Jinja2, single `templates` object imported everywhere).
+- Frontend: no framework, no build step. Plain ES modules, one class
+  per file, small shared utilities (`Http`, `Poller`, modal, toast).
+- Database: one embedded relational file with WAL mode for small to
+  medium scale (DevPlace: SQLite via `dataset`, WAL, busy timeout,
+  mmap). Synchronous local calls are fine when they are
+  sub-millisecond; do not make the data layer async for fashion.
+- Auth: session cookie for browsers plus API key and Basic for
+  machines, resolved in one `get_current_user` choke point. No JWT
+  unless you need third-party verification.
+- Static assets: content-addressed or boot-versioned URLs served
+  immutable (`/static/v<ts>/...`), one helper builds every URL.
+- Background work: one in-process queue with inline fallback so tests
+  stay deterministic and production stays fast.
+
+Hosting example: keep customers, services, invoices, tickets in one
+SQLite/Postgres schema behind one data module. Serve the control
+panel as HTML, the reseller API as JSON from the same handlers.
+
+## 3. Repository layout that scales
+
+Mirror URLs with code paths, one segment per directory:
+
+- `routers/` mirrors the URL tree. Flat file for one resource
+  (`feed.py`), package directory for sub-resources (`projects/`).
+  Each leaf owns an `APIRouter`, the package `__init__.py` aggregates.
+- `templates/` mirrors pages, extends one `base.html`. Page CSS in
+  `extra_head`, page JS in `extra_js`. Shared partials for repeated
+  UI (avatar link, user link, pagination, report button).
+- `static/js/` mirrors behavior, one class per file, instantiated as
+  `app`. Shared utilities live once and are reused, never forked.
+- `static/css/` uses design tokens, no literal colors in page files,
+  one closed breakpoint set, one z-index scale.
+- `services/` holds background services behind one base class and one
+  manager (start/stop/status/logs). Each service owns its tables and
+  its admin controls.
+- `tests/` mirrors the same tree by path: `tests/api/...` for HTTP,
+  `tests/e2e/...` for browser, `tests/unit/...` for pure logic.
+
+Rule: if you cannot guess the file from the URL, the layout is wrong.
+
+## 4. Single data root and single config module
+
+All runtime artifacts live under one root (`DATA_DIR`), every path
+derived from it in one config module, created at boot:
+
+- Database file, uploads, attachments, generated archives, keys,
+  locks, backups, service state.
+- Stored DB values are relative (`directory` + `stored_name`), so a
+  layout move never needs a DB rewrite.
+- One `DATA_PATHS` registry lists every path; one `ensure_data_dirs()`
+  creates them before anything writes.
+
+Hosting example: `data/` holds `app.db`, `uploads/`, `invoices/`,
+`backups/`, `locks/`, `keys/`. Point `DATA_DIR` at a volume in prod.
+
+## 5. Request pipeline (same for every route)
+
+1. Single app factory: mount `/static`, register routers, install
+   middleware in fixed order (timing outermost, then security
+   headers, rate limit, maintenance gate, error handlers).
+2. One auth resolution: cookie, API key header, Bearer, Basic,
+   all in `get_current_user`. Guards: public read
+   (`get_current_user`), member write (`require_user`), admin
+   (`require_admin`).
+3. One response helper (`respond()`): same context renders HTML for
+   browsers and JSON for `Accept: application/json` via a response
+   schema. A context key missing from the schema is dropped from
+   JSON by design, so schemas are explicit contracts.
+4. One validation style: Pydantic form models bound from forms,
+   one global validation-error handler (re-render or redirect).
+5. One timing mechanism: outermost middleware stamps start time and
+   sets `X-Response-Time`. Never re-time per route.
+6. Rate limit only mutations (`POST/PUT/PATCH/DELETE`), keyed by
+   real IP, tunable from settings. Reads stay fast and exempt.
+
+## 6. Data conventions that prevent entire bug classes
+
+- Primary keys are opaque string IDs (`uid`), slugs accept slug or
+  bare ID via one resolver. Slugs embed the random tail of the ID,
+  never a timestamp prefix (prefix sharding funnels writes).
+- Soft delete everywhere user content is removable: `deleted_at` +
+  `deleted_by`, live rows are `deleted_at IS NULL`. Every insert
+  writes both columns, every list filters them. Only garbage
+  collection hard-deletes. One admin Trash restores/purges by event.
+- Ownership rule: edits are owner-only, deletes are owner-or-admin,
+  checked by one helper. Admin seniority: junior admins cannot act
+  on senior admins.
+- No N+1: batch helpers (`get_users_by_uids`, counts by ID lists,
+  paginators) are the only way to load related rows in lists.
+- Idempotent schema init: ensure full column set before indexes,
+  because auto-schema tools create partial tables from first insert.
+- Toggles revive, never duplicate: look up ignoring deleted flag,
+  stamp on off, clear on on, under one shared stamp for cascades.
+
+Hosting example: canceling a server is a soft delete with one stamp
+covering service, DNS rows, and scheduled jobs, restorable from Trash
+until GC purges it.
+
+## 7. Frontend rules that keep UI consistent
+
+- One base template owns nav, head, modals, toasts, timing badge.
+  Nav active state is one global, never inline path checks.
+- Never hardcode `/static/...`. One helper builds versioned URLs in
+  templates and one in JS.
+- Server renders content that exists at request time (SEO, no-JS,
+  speed). Client pipeline is only for live content (chat bubbles,
+  streamed results), always sanitized fail-closed.
+- Dates stored as UTC ISO, rendered as `<time data-dt>` and
+  reformatted to viewer timezone client-side, one format for users
+  (DevPlace: DD/MM/YYYY).
+- Modals, lightbox, toasts, floating windows, scroll memory: one
+  implementation each, reused by class name. No inline JS.
+
+## 8. Background jobs and services (one pattern)
+
+- One generic fire-and-forget queue: `submit(fn, *args)`. When the
+  consumer runs, it defers; when it does not (tests, full queue),
+  it runs inline so behavior stays deterministic.
+- One base service class: `run` loop, supervised start/stop, status,
+  logs, settings. One manager registers all services.
+- One async-job pattern for slow work (archives, audits, reports):
+  enqueue (`POST .../run`), poll (`GET .../{uid}`), read report
+  (`GET .../{uid}/report`), expire and prune by CLI.
+- Multi-worker safety: schema work behind one init lock, background
+  services elected by one service lock so exactly one worker owns
+  them. Never assume single-process in job code.
+
+Hosting example: provisioning, backups, SSL renewal, and usage
+metering are all job services with run/poll/report plus
+`cli <domain> prune` retention commands.
+
+## 9. Testing: three tiers, one tree, no skips
+
+- Tiers by fixture, not by folder debate:
+  - `unit`: pure in-process, no HTTP, no browser.
+  - `api`: HTTP integration against a live test server + temp DB.
+  - `e2e`: Playwright browser, real user flows.
+- Test server runs on its own port with its own temp DB and data
+  dir, background services disabled. One serial process, no
+  parallelism, so results are stable.
+- Every run reports every failure (`-rf`), triage cheapest first:
+  unit+api (~minutes), then browser tier, then `--last-failed`
+  loop until empty.
+- Required browser habits: explicit `domcontentloaded` on
+  navigations, visible-state waits over sleeps, scoped selectors,
+  global settings restored in `try/finally`.
+- Gate before suite: clean app import, per-language syntax check,
+  linter on touched files (catches missing imports that compile
+  checks miss), no forbidden characters or patterns.
+
+Quality bar: the full suite (all three tiers, every test) passes
+before a change is done. A red test covering your change is the
+requirement, not a stale artifact. Never narrow a run to make it
+pass.
+
+## 10. Extra verification for money, state, and races
+
+Example-based tests are blind to wrong formulas at untried inputs,
+long-sequence invariant breaks, and races. For spendable resources
+(credits, coins, quotas), bounded state machines (tiers, levels),
+or read-then-write mutations reachable from two requests, add four
+disposable layers against a temp DB (not committed tests unless
+asked):
+
+1. Property checks over the full input domain (monotonicity,
+   bounds, non-negativity) across hundreds of values.
+2. Stateful fuzzing: randomized action sequences across many
+   entities, invariants re-checked after every action.
+3. Real-process concurrency: separate OS processes (not threads),
+   fresh production-like rows (never pre-zero NULL columns),
+   exact success counts and exact final totals. Fix races with one
+   atomic conditional `UPDATE ... WHERE <precondition>` checked by
+   real `rowcount` at the chokepoint.
+4. Static analysis on every touched file (`pyflakes`/`ruff`), which
+   catches runtime `NameError` paths the other layers may miss.
+
+Hosting example: apply this to credit spend, plan upgrades,
+affiliate payouts, and concurrent provisioning of the last IP or
+stock-limited node.
+
+## 11. Operations: deploy, verify, prune
+
+- One-command environments: `install`, `dev` (reload, one worker),
+  `prod` (multi-worker, no template reload, real backlog), `test*`,
+  `coverage`, load test. Every Python target uses the project venv.
+- No bytecode in repo: `PYTHONDONTWRITEBYTECODE=1` for all targets,
+  `clean` removes venv and stray artifacts.
+- CI runs the full suite serially on every push/PR, publishes
+  coverage and failure screenshots. CI green before merge.
+- Production DB is never touched without explicit written
+  confirmation plus a two-factor token; disposable scripts always
+  target a scratch DB via env override.
+- Retention is a feature: every expirable domain gets
+  `prune` (expired only) and `clear` (everything) CLI commands,
+  wired to the same GC the server uses.
+- Backups are first-class: targets, worker, schedules, offload,
+  download restricted to the primary admin, prune missing files.
+
+## 12. Security, moderation, and trust checklist
+
+- Passwords hashed with a slow KDF (PBKDF2-SHA256), session tokens
+  random 256-bit, per-process TTL cache keyed by token.
+- Ownership checked server-side on every mutation; deletes confirm
+  explicitly and audit; destructive automation actions require a
+  two-step confirm flag declared in their schema.
+- Every user-visible content table is reportable by construction:
+  registry entry, object URL resolver, report button in the action
+  bar. Private-only tables are listed as unreportable with a reason,
+  enforced by a test that fails on unclassified tables.
+- Outbound HTTP goes through one stealth/guarded client (consistent
+  TLS + headers + proxy + SSRF guard), never bare clients per call.
+- Audit log is append-only, never raises into the caller, with one
+  catalogue of event keys. Admin-only read.
+- Privacy docs and store declarations update in the same change as
+  any new personal-data collection or third-party transmission.
+
+Hosting example: tickets, reviews, and public server comments are
+reportable; invoices and API tokens are private-by-design with
+written reasons; provisioning calls go through the one guarded
+client with proxy support.
+
+## 13. Docs, SEO, and API surface
+
+- Every public/auth endpoint gets prose docs plus an interactive
+  API entry (params, auth, sample response). Public pages get SEO
+  context and JSON-LD; sitemap and robots are served, not static.
+- One docs registry (`DOCS_PAGES`) owns prose pages; API docs own
+  endpoint entries. New route without docs is incomplete.
+- README stays product-facing (routes, config, env vars, features).
+  Nested `CLAUDE.md` files hold subsystem mechanics next to the code
+  so the always-loaded root doc stays small.
+- Version static assets, canonical URLs per listing, breadcrumbs,
+  related content, and one default OG image.
+
+## 14. Development flow (the daily loop)
+
+Every feature follows the same eight steps in data-flow order, and a
+failed step blocks the rest (never skip ahead):
+
+1. Understand. Read the router, template, matching tests, and the
+   subsystem doc. Trace input model to router to data helper to
+   response (HTML and JSON). Find a relatable existing example and
+   match it structurally and visually; if none exists, stop and agree
+   on the new pattern before building.
+2. Data layer. Query/batch helpers first (never inline N+1), input
+   model, JSON response schema (every exposed key declared or it is
+   silently dropped), idempotent schema/index changes.
+3. Server layer. Handler with the right guard (public/member/admin),
+   specific paths before catch-alls, HTML+JSON via one responder.
+4. View layer. Extend base, reuse partials and globals, page CSS/JS
+   in the standard blocks, one ES class per file.
+5. Safety layer. Reportable/private classification, ownership checks,
+   confirm gates, audit events, privacy-doc update if new personal
+   data or third-party transmission appears.
+6. Agent + docs layer. Tool action per user-askable operation,
+   endpoint doc entry, prose page if user-facing, SEO context and
+   sitemap entry if indexable. This step is the most-forgotten; do
+   not skip it.
+7. Document. Product README for user-visible change, subsystem doc
+   for new mechanics or pitfalls, root doc only for new global rules.
+8. Validate. Clean import, per-language syntax check, linter on
+   touched files, full three-tier suite green (see section 9), plus
+   the money/state/race procedure where it applies.
+
+Failure triage is cheapest-first: fast tiers (unit+api, minutes)
+before browser tier, then re-run only failures (`--last-failed`)
+until empty. One pass reports every failure; fix the list, not one
+bug per pass.
+
+Session rule: commit, deploy, verify in the same session, in that
+order. A change that is not running in production is not done. After
+deploys, verify live; green locally means nothing until prod
+confirms it.
+
+## 15. Workflows and automation
+
+- One command surface. Every repeated action is a named target or CLI
+  command (`dev`, `prod`, `test`, `test-fast`, `test-failed`,
+  `coverage`, load test, `prune`, backups). No tribal shell
+  one-liners; if it is run twice, it gets a name.
+- DTAP pipeline. Development (reload, one worker) to Test (CI serial
+  suite + coverage + failure screenshots, green before merge) to
+  production (multi-worker, no template reload, real backlog).
+- Scheduled hygiene inside the system, not in heads: retention,
+  cleanup, quota resets, and health checks run on loops or CLI
+  commands with dry-run defaults and narrow scopes for destructive
+  ops. Destructive operations are dry-run first, explicitly
+  confirmed, date-guarded or allowlisted.
+- Load testing is a target, not an event: scripted Locust run
+  against a scratch DB with fixed users, spawn rate, and run time,
+  producing an HTML report.
+- Production guardrails are enforced, not remembered: a hook denies
+  commands reaching the live DB without explicit written
+  confirmation plus a second approval; disposable scripts always
+  target scratch databases via env override.
+
+Hosting example: `provision`, `suspend`, `backup-run`,
+`ssl-renew`, `usage-meter`, `invoice-prune` are all named commands
+with `--dry-run`; nightly loops handle expiry, renewal, and status
+checks with human-readable pressure states.
+
+## 16. Agents: in-product assistant, services, and coding help
+
+DevPlace quality comes partly from treating agents as first-class
+consumers of the same routes humans use:
+
+- In-product assistant (DevPlace: Devii). A conversational operator
+  over the real API: per-owner sessions and channels (web, terminal,
+  chat bridge), a tool catalog where each tool mirrors one route
+  with matching auth, confirmation gates on destructive tools (first
+  call refused, agent shows exact target, second call passes
+  `confirm=true`), per-user cost attribution and quotas through one
+  AI gateway, and usage/ledger pages per user. New feature rule: if
+  a user could ask the assistant to do it, it gets a tool.
+- Gateway pattern. Every AI/model call flows through one internal
+  gateway (usage ledger, provider/model routing, per-call cost
+  headers), so spend is attributable and every consumer (correction,
+  modifier, grading, chat) shares quotas and audit.
+- Background service agents. Crawlers, importers, reconcilers, and
+  persona bots run as supervised services under one manager with
+  start/stop/status/logs and admin pages (DevPlace: news importer,
+  bot fleet with live monitor, container reconciler, audit writer).
+  Exactly one worker owns them via a service lock.
+- Coding-agent support. Nested subsystem docs next to the code so an
+  agent loads only what it touches; strict conventions (no second
+  implementation, named helpers, closed token/breakpoint/z-index
+  sets) so generated code matches; tool catalog and docs registry
+  so the agent can act and document through the same contracts.
+- Human authority. Agents propose and execute reversible work;
+  destructive, cross-user, or policy-crossing actions need explicit
+  human confirmation, seniority checks where roles exist, and an
+  audit trail. When a floor is hit (retention minimum, protected
+  path), the agent holds and pages a human instead of deleting.
+
+Hosting example: a support assistant with tools like `server_reboot`
+(public read tools open, mutating tools auth-gated, destructive
+tools confirm-gated), all spend metered per customer through your
+gateway, provisioning and renewal running as supervised services.
+
+## 17. Documenting: what lives where, and when
+
+Documentation is layered by audience and distance from the code, and
+every layer updates in the same change as the code it describes:
+
+- Source code: no comments, no docstrings. Code is self-documenting
+  through names, small helpers, and one obvious way per task. A
+  decision worth recording goes in the change description or the
+  subsystem doc, never as deliberation text in the source.
+- Subsystem docs (DevPlace: nested `CLAUDE.md` next to the code).
+  Each directory that owns a mechanic holds its own doc: helpers,
+  pitfalls, cross-layer wiring, worked examples. An agent or human
+  loads only the docs for the area being touched, so the always-
+  loaded cost stays flat as the project grows.
+- Root doc (DevPlace: `CLAUDE.md`, `ARCHITECTURE.md`). Global rules,
+  commands, and architecture only. A per-feature detail never lands
+  here; a new global rule always does. The architecture atlas is
+  measured from the running app and schema (counts, diagrams), not
+  written from memory, and disagreements between docs and code are
+  recorded explicitly.
+- Product README. User-visible surface: routes, config, env vars,
+  features, quick start. Updated when behavior a user can see
+  changes.
+- User docs site (DevPlace: `/docs` with a `DOCS_PAGES` registry).
+  Prose pages per audience tier plus an interactive API reference
+  where every endpoint entry carries params, auth, and a sample
+  response. A new public or auth endpoint without a doc entry is
+  incomplete by definition.
+- Privacy and store declarations. Any new personal-data category or
+  third-party transmission updates the privacy doc and platform
+  declarations in the same change, never as a follow-up.
+- Event and reason registries. Audit event keys, report reasons, and
+  similar closed sets live in one catalogue each, so every client
+  and test renders the same list.
+
+Rule: docs state what the system does today, with gaps listed next
+to the code that will close them. No fiction, no roadmap prose.
+
+Hosting example: `billing/CLAUDE.md` documents proration and retry
+rules next to the billing code; the root doc only says billing
+exists and which commands run it; `/docs` gains a prose page plus
+one API entry per new endpoint in the same change.
+
+## 18. Roles, permissions, and ownership
+
+One small role set, enforced server-side at every surface (web UI,
+REST API, and agent tools alike):
+
+- Roles (DevPlace: guest, member, admin, primary admin). Stored as
+  exact strings, tested through one `is_admin()` helper, never
+  hand-rolled compares. Any write to a role invalidates the cached
+  role lookups.
+- Guests read public pages; members write their own content;
+  admins moderate and operate. Public reads resolve the viewer but
+  never require login; every write names its guard explicitly.
+- Ownership first: edits are owner-only, deletes are owner-or-admin,
+  checked by one helper comparing resource owner to actor. Admins
+  can remove abuse but cannot rewrite someone else's words.
+- Seniority among admins: a junior admin (later registration) cannot
+  mutate a more senior admin's account or content. Every per-user
+  admin mutation is gated by one seniority predicate, denials are
+  audited, and the gate is server-side so it also covers agent
+  tools. One primary admin (the first admin account) is the single
+  exception with full visibility and full control, including
+  private-by-admin content and restricted downloads.
+- Visibility predicates are single functions, never inline checks:
+  e.g. `can_view(project, user)` decides private-content access in
+  one place (owner sees own, admins see members' private rows, but
+  an admin's own private rows stay visible only to that admin
+  except for the primary admin). Container and workspace isolation
+  get their own stricter predicates on the same pattern.
+- Machines authenticate as users: every account holds an API key,
+  plus issuable scoped tokens; the same guards apply regardless of
+  credential type, so the REST API cannot do what the UI forbids.
+- Agents act as the asking user: tool auth mirrors route guards,
+  destructive tools add confirmation gates, and every admin tool
+  passes through the same seniority and audit path as the web UI.
+
+Rule: if a permission check appears twice in different words, one
+of them is a bug. Hoist it into the single predicate and call it
+from both places.
+
+Hosting example: guest (pricing, status), customer (own servers and
+invoices), support (view customers' servers, restart but not delete;
+junior support cannot touch senior staff accounts), owner (full
+access plus backup downloads and billing refunds). One
+`can_view_server` / `can_manage_server` pair gates panel, API, and
+assistant tools together.
+
+## 19. Replication checklist for your hosting site
+
+Use this order; it is the data-flow order DevPlace follows:
+
+1. Scaffold: app factory, config with one data root, shared
+   templates, response helper, auth choke point, middleware stack.
+2. Data: users, sessions, settings, then one domain (products).
+   Add soft-delete columns, batch helpers, idempotent init.
+3. Server: public reads first (HTML+JSON via one handler), then
+   member writes with guards, then admin views.
+4. View: base template, tokens, partials, one JS utility set.
+   Server-render listings and detail pages.
+5. Safety: reportable/private classification, ownership checks,
+   confirm gates, audit events.
+6. Automation + docs: tool action per user-askable operation,
+   API doc entry per endpoint, SEO context per public page.
+7. Verification: import gate, lint touched files, full three-tier
+   suite green, plus the four-layer money/state/race procedure
+   where it applies.
+8. Ops: venv targets, CI serial suite, prune/clear CLIs, backups,
+   production-DB guard, deploy then verify live.
+
+## 20. What to copy literally vs adapt
+
+Copy literally: single data root, soft-delete columns and filters,
+batch loaders, one response helper, one auth resolver, test tiers
+and temp-DB server fixture, prune/clear per domain, audit-never-
+raises, versioned static URLs.
+
+Adapt to hosting: table list (customers, plans, servers, invoices,
+tickets, status incidents), provisioning job services, payment and
+registrar integrations behind the one outbound client, usage
+metering and quota rules, status page and notifications.
+
+If you keep the constraints and the verification loop, the domain
+can change completely and the quality transfers with it.

+# Quality Versioning Playbook: App, Assets, Docs, and Git
+
+Generic companion to `quality_software.md`. It covers how DevPlace
+versions its application, its static assets, and its git history,
+plus the one practice DevPlace does NOT have today and you should
+adopt from day one: versioned markdown docs.
+
+Honest baseline (researched 2026-10-11, do not assume otherwise):
+
+- App version: single source `pyproject.toml`, auto-bumped patch on
+  every commit by a checked-in pre-commit hook. Real and working.
+- Asset version: composed `{APP_VERSION}-{BOOT_ID}`, stamped into
+  every static URL, served immutable. Real and working.
+- Git: trunk `master`, remote `production` branch, per-ticket
+  branches, CI gate on push/PR to master. Real and working.
+- Tags: none. Changelog file: none. Markdown versioning: none.
+  These are gaps, and sections 4 and 6 below define what to do
+  instead of copying the gap.
+
+## 1. App versioning: one source, auto-bumped
+
+- One file owns the version (DevPlace: `pyproject.toml`
+  `project.version`, currently `1.0.x`). The running app reads it
+  live at boot (DevPlace: `config.APP_VERSION` via `tomllib`), so
+  the version in code and the version on disk can never drift.
+- A checked-in pre-commit hook bumps the patch number on every
+  commit (DevPlace: `.githooks/pre-commit`, activated by
+  `git config core.hooksPath .githooks` in the install target).
+  Skips merge commits and commits that already touch the version
+  line, so a manual minor/major bump is never double-bumped.
+- Semver discipline: patch is automatic (every commit), minor is a
+  manual commit when a user-visible feature lands, major is a
+  manual commit on breaking change. Minor/major bumps are ordinary
+  commits whose message says what the release contains.
+- The version is visible at runtime: stamped into a meta tag
+  (DevPlace: `<meta name="asset-version">` in `base.html`) so any
+  page view, bug report, or screenshot names the exact build.
+
+Hosting example: the control panel footer and every support ticket
+show `v2.14.3`; support never asks "which version are you on".
+
+## 2. Asset versioning: cache forever, deploy instantly
+
+- Compose the asset version from app version plus boot id:
+  `STATIC_VERSION = {APP_VERSION}-{BOOT_ID}` where the boot id is a
+  deploy-provided marker with a wall-clock fallback.
+- Stamp it into every app-owned static URL
+  (`/static/v<version>/...`) through one URL helper, and serve that
+  path immutable with a one-year `max-age`.
+- Keep the reverse proxy in sync: the versioned-path location regex
+  must accept dots and hyphens, not digits only, or the immutable
+  header silently stops applying (this was a real production bug
+  class here, fixed once the version segment stopped being a bare
+  timestamp).
+- Never hardcode a static path; every template and script builds
+  URLs through the one helper, so a version-shape change touches
+  one function.
+
+## 3. Git workflow: trunk, tickets, production
+
+- Trunk is `master`. All work lands there through small commits;
+  CI (serial full suite, coverage, failure screenshots) runs on
+  every push and PR to master and must be green before merge.
+- One branch per ticket or task, named after the tracker
+  (`ticket-123`, `112-short-slug`). Short-lived: branch, commit,
+  merge, delete. No long-running feature branches.
+- One `production` branch (or tag set, see section 6) marks what is
+  deployed. Development happens on master; promotion to production
+  is a deliberate merge, followed by deploy and live verification.
+- Commit messages: imperative summary line under 72 chars, blank
+  line, body explaining why (not what, the diff shows what).
+  Optional trailers for attribution (`Co-Authored-By`) and session
+  links. Reverts say what behavior returned and why.
+- Never rewrite published history: no amend/push-force, no rebase
+  of shared branches, no `reset --hard` on anything pushed. Fix the
+  working tree forward; a mistaken commit is corrected by a new
+  commit.
+- Hooks live in the repo (`.githooks/`) and are wired by the
+  install target, so every clone gets the version bump and any
+  future checks with zero manual setup.
+
+## 4. Markdown versioning: every doc carries its version
+
+This is the rule DevPlace does not follow yet: **every markdown
+file is versioned on every update.** Adopt it from the start; it
+costs one line per edit and buys traceability for every claim a
+doc makes.
+
+Scheme (copy literally):
+
+1. First line of the file is an invisible HTML comment:
+   `<!-- doc: <filename> | version: X.Y.Z | updated: YYYY-MM-DD -->`
+   It renders nothing and survives every markdown renderer.
+2. Bottom of the file is a `Doc history` table with one row per
+   version: version, date, one-line change note.
+3. Doc-semver: MAJOR for restructure or section renumbering, MINOR
+   for a new section or new rule, PATCH for wording, fixes, or
+   example updates. Every update bumps exactly one level and adds
+   exactly one history row.
+4. The version bump and the content change ship in the same commit,
+   so `git log -p <doc>` and the history table always agree.
+5. Cross-doc references name the section, not the version ("see
+   `quality_software.md` section 9"), so minor doc bumps never
+   cascade into other files.
+
+Enforcement options, cheapest first: a pre-commit check that fails
+when a staged `.md` lacks a matching version-line change (same
+pattern as the app-version hook, inverted: docs must be touched by
+hand, so the hook only verifies); a CI grep that every tracked
+`.md` starts with the `doc:` comment; a unit test listing tracked
+markdown files and asserting the header parses.
+
+Hosting example: `docs/sla.md` at `3.1.0` and `docs/pricing.md` at
+`5.0.2` evolve independently; a customer dispute cites "SLA v3.1",
+not "the docs, at some point".
+
+## 5. What gets a version vs what gets a timestamp
+
+- Versioned (semver, comparable, citable): the app, each markdown
+  doc, API contracts, terms/SLA/pricing pages, database export
+  formats, agent tool catalogs.
+- Timestamped (point-in-time, never compared): deploys (boot id),
+  backups, audit events, usage ledger rows, generated reports.
+- Never versioned alone: a bare counter with no history row, a date
+  with no change note. A version you cannot diff is decoration.
+
+## 6. Releases and tags: close the gap deliberately
+
+DevPlace has no tags and no changelog file; promotion is tracked by
+the `production` branch. For a hosting company, where customers and
+auditors ask "what changed and when", close this gap:
+
+- Tag every production promotion with an annotated tag
+  (`v2.14.0`, message = release notes summary). Tags are cheap,
+  immutable pointers; the branch can move, the tag cannot.
+- Keep one `CHANGELOG.md` (itself doc-versioned per section 4)
+  with one entry per minor/major release: date, tag, added,
+  changed, fixed, security notes. Patch releases batch into the
+  next minor entry; no per-commit changelog spam.
+- Release flow in order: land feature commits on master (CI green),
+  manual minor/major bump commit, merge master into production,
+  tag, deploy, verify live, write the changelog entry. A release
+  that is not verified live is not released.
+
+## 7. Replication checklist for your hosting site
+
+1. Single version source read live by the app; pre-commit hook
+   auto-bumps patch; minor/major are manual release commits.
+2. Asset URLs carry `{version}-{boot-id}`, served immutable;
+   proxy regex accepts the full version alphabet.
+3. Trunk `master`, ticket branches, `production` promotion target,
+   CI gate on master, no history rewrites, hooks in-repo.
+4. Every `.md` starts with the `doc:` version comment and ends with
+   a history table; every update bumps; CI verifies the header.
+5. Terms, SLA, pricing, and API contracts are versioned docs with
+   citable versions, not wiki pages.
+6. Annotated tags plus one changelog for customer-facing releases;
+   release = merge, tag, deploy, verify live, changelog entry.

+**Residential proxy donation works by having donors run a lightweight client that opens a persistent outbound tunnel (almost always WebSocket/WSS) to your central server. Your server then multiplexes incoming SOCKS5 or HTTP CONNECT requests over those tunnels so traffic exits through the donor’s residential IP.**
+
+This is a reverse-proxy style architecture. The client never listens on a public port; it only dials out. That is why WebSocket (or a similar long-lived bidirectional channel) is the natural transport.
+
+### Core client design (common to all options)
+1. Client authenticates (token / account) and opens a WebSocket to your server.
+2. Server treats each live WebSocket as a residential exit node.
+3. When a customer requests a connection through that node, the server sends a framed “open TCP to host:port” message over the WebSocket.
+4. The client opens the TCP socket locally and bidirectionally relays bytes.
+5. Keep-alives, automatic reconnect with exponential backoff, and optional bandwidth/rate limits on the client side.
+
+Open-source references that implement exactly this pattern include `residential-proxy-aggregator` (Python WS server + client agents), `pywssocks`, and various WS-SOCKS tools.
+
+### Option comparison
+
+| Option | Reliability / Always-on | Install friction | Resource use | Store / distribution | Best for | Major limitations |
+|--------|-------------------------|------------------|--------------|----------------------|----------|-------------------|
+| **Browser extension (MV3)** | Medium | Very low | Medium (browser process) | Chrome Web Store / Firefox AMO | Mass casual donors | Service worker idle timeouts; store policies; only while browser runs |
+| **systemd user service** (or Windows Service / LaunchAgent) | High | Medium | Very low | Binary + unit file / package | Technical / always-on Linux users | Platform-specific packaging |
+| **Desktop app** (Tauri / Electron / native) | High | Medium-High | Low–Medium | Website / GitHub releases | Cross-platform reliability | Larger download, code-signing |
+| **Plain webpage / PWA with open tab** | Low | Lowest | Low while open | Just a URL | Quick experiments | Tab throttling, user closes tab, background limits |
+| **Service Worker alone** | Poor | Low | Low | Part of a site | Not recommended as primary | Cannot reliably hold long-lived outbound tunnels |
+
+### 1. Browser extension (Manifest V3)
+Technically feasible and the lowest-friction option for many donors.
+
+- Background service worker opens the WebSocket.
+- Since Chrome 116, WebSocket activity resets the service-worker idle timer, but you still need an explicit keepalive (send a ping every ~20 seconds).
+- Use `chrome.alarms` (minimum ~30 s) as a durable backup that survives worker termination and forces reconnects.
+- You will also need careful reconnect logic, state persistence (e.g. `chrome.storage.session`), and handling of the case where the worker is killed mid-relay.
+
+**Store and policy issues**
+Chrome Web Store (and Firefox AMO) require a clear single purpose and honest disclosure. An extension whose primary function is “share my residential connection / bandwidth” must state that prominently. Proxy-related extensions receive extra scrutiny. Misleading claims or hidden data collection will get you removed. Historical precedent exists (uProxy was a browser-extension peer-proxy system, later discontinued and succeeded by Snowflake).
+
+**Practical limits**
+- Only runs while the browser is open.
+- Higher CPU/battery impact than a native binary.
+- On mobile Chrome the background behaviour is even more restricted.
+
+### 2. systemd user service (Linux) / equivalent on other OSes
+This is one of the cleanest long-running options.
+
+- Ship a small static binary (Go, Rust, or even a Node/Python script).
+- Provide a user unit file (`~/.config/systemd/user/residential-proxy.service`).
+- `systemctl --user enable --now residential-proxy.service`.
+- It reconnects automatically, uses almost no resources when idle, and survives reboots (with lingering enabled).
+
+Windows equivalent: a Windows Service or scheduled task. macOS: LaunchAgent. This matches the architecture used by the open-source residential-proxy-aggregator project (C++ Windows service + watchdog).
+
+### 3. Desktop application (Tauri preferred over Electron)
+Tauri gives you a small native binary with a system tray, automatic updates, and full control over the WebSocket and TCP relay. Electron works but is heavier. This is the most reliable cross-platform choice if you want something that “just stays on” without requiring users to keep a browser open.
+
+### 4. Service Worker / PWA
+A regular service worker (or even an extension service worker without the keepalive tricks) is **not** a good primary client.
+
+Service workers are event-driven and get terminated after short idle periods. They cannot reliably maintain a persistent outbound TCP/WebSocket tunnel that is ready to accept new SOCKS connections at any moment. They are useful for secondary tasks (notifications, caching) but not as the proxy agent itself. Background throttling on inactive tabs and especially on mobile makes a pure PWA approach unreliable for always-available residential exits.
+
+### Other practical considerations
+
+- **Keepalive & reconnect**: Mandatory everywhere. WebSocket idle timeouts on reverse proxies/load balancers are often 60–100 s; your application-level heartbeat should be more aggressive.
+- **Bandwidth and rate limiting**: Enforce soft and hard limits on the client so a donor is not surprised by a sudden bill or congestion.
+- **Consent & transparency**: Show clear UI that the user is sharing their IP and bandwidth, with an easy off switch. Log (or at least allow users to see) roughly how much traffic has been relayed.
+- **ISP terms**: Many residential ISPs prohibit running open proxies, commercial use of the connection, or significant bandwidth resale. Donors should be warned.
+- **Abuse & liability**: Residential proxy pools are frequently abused for scraping, credential stuffing, ad fraud, etc. You will need authentication of donors, monitoring, the ability to ban nodes quickly, and clear Terms of Service that shift responsibility appropriately. Pure “donation” models still create platform liability if the traffic is used illegally.
+- **Authentication**: Prefer short-lived tokens or account-based auth so you can revoke a donor’s participation instantly.
+- **Mobile**: Background execution limits make reliable always-on clients difficult on iOS and restricted on Android. Not recommended as a primary platform.
+
+### Recommended starting path
+
+1. **Prototype** with a simple Node/Go/Rust WebSocket client + a matching server that exposes a SOCKS5 listener (look at `pywssocks` or the residential-proxy-aggregator design for structure).
+2. **First distribution channel**: browser extension (for reach) + a tiny systemd/LaunchAgent/Windows service binary (for reliability).
+3. Later add a polished Tauri tray app if the project gains traction.
+
+The WebSocket-upstream model is the right foundation. The choice of packaging mainly affects how many people will actually leave the client running and how painful the operational reality becomes.
