+# Management Layer Plan — Zero Dev Telegram
+
+Status: **PLANNING COMPLETE / IMPLEMENTATION NOT STARTED**
+Branch for delivery: `feat/management-layer`
+Scope: replace the manual installation experience with installer + wizard +
+TUI + local Web GUI + CLI + safe config/secrets + doctor/backup/update, while
+keeping this project **Zero Dev Telegram** (Telegram-first, small teams,
+simpler than Zero Dev Web).

+
+## Executive summary of findings
+
+- The repository already ships a strong **control-plane core** (identity,
+  plans, durable executions, worktrees, providers incl. OpenAI-compatible +
+  Anthropic adapters, usage accounting, audit) and a working Telegram
+  adapter/polling/webhook runtime — but **zero management tooling**.
+- A new user today must: install Git+uv manually, create a venv, export env
+  vars (bare start exits with a config error), boot an API server, then drive
+  ~8 REST calls with JSON bodies to reach a live bot — and even then hits a
+  **dead end**: external-identity verification exists only as a Python method
+  (`identity_service.py:355`) with no route, so inbound messages are denied
+  (`ignored_unlinked`). Reproduced as R1–R7 in doc 02.
+- There is **no access policy** beyond "verified identity ∧ project member":
+  any member's linked Telegram account can use every feature of every group
+  the bot is in. Public-bot accidents are one enabled binding away.
+- Zero Router contains four genuinely portable concepts (declarative
+  YAML provider/model catalog, weighted-score candidate selection with
+  circuit-breaker-aware exclusion, health state machine, envelope crypto)
+  and large rejected surfaces (gateway app, org/team auth, billing store,
+  Redis infra). Verdicts in doc 03.
+
+## Product decisions taken (none blocking)
+
+| Decision | Choice | Why |
+|---|---|---|
+| Install URL | `https://getzerodev.ai/install.sh`, fallback `https://raw.githubusercontent.com/mhrsdev/zero-agent-dev-telegram/main/scripts/install.sh`; single `INSTALL_URL_BASE` variable in script | spec allows temporary centralized URL |
+| Language/runtime | Python only (no second runtime) | repo is Python; Textual covers TUI without Node |
+| TUI framework | **Textual** (maintained, keyboard-first, NO_COLOR aware) | spec §8 |
+| GUI stack | Server-rendered Jinja2 + htmx, mounted at `/admin`, loopback-only default | reuses existing FastAPI/Jinja2; no SPA build chain |
+| Bot API vs User-session | Ship **Bot API only** in v1; User Session out-of-scope until designed safely | spec §4 warns against mixing; no session code exists today |
+| Telemetry | None by default; opt-in stub only | spec §15 |
+| Channels | `stable` (git tags) and `beta` (branch); no `dev` channel publicly | simplicity |
+| Where management code lives | `src/zero/manage/**` + thin `zero` console script in the same package/repo | one repo, one runtime, clean import boundary from core |

+# 01 — Repository Audit (zero-agent-dev-telegram @ main)
+
+## 1. Identity of the codebase
+
+Python 3.11+ package `zero-develop` (`pyproject.toml`), console script
+`zero-develop = zero.cli:main`. Layered per ADRs: `domain/` → `app/` services
+→ `persistence/` (SQLite + 30 SQL migrations) → `web/` + `adapters/`.
+Test suite: 563 passing / 16 platform-skips on the remediated tree.
+
+## 2. Today's install path (the thing we are replacing)
+
+`README.md:105-123` — manual: install Git **and uv** → `git clone` →
+`uv venv --python 3.12` → activate → `uv pip install -e ".[dev]"` →
+`export ZERO_ENV=development` → `zero-develop` → open `/web`, `/docs`.
+`scripts/run_dev.sh:17-34` is a POSIX dev helper (PYTHONPATH=src, uvicorn
+--reload); it explicitly defers supervision ("not a deployment story").
+No Dockerfile, no compose, no systemd unit anywhere in the tree.
+`.env.example` documents variables but is never auto-loaded
+(`README.md:167-169`; `main.py:57-68` reads process env only).
+
+## 3. Configuration surface today
+
+Parsed in `src/zero/config.py load()`:
+`ZERO_ENV` (required), `ZERO_DATABASE_URL`, `ZERO_LOG_LEVEL`,
+`ZERO_SECRET_KEY` (prod ≥32B), `ZERO_AUTH_REQUIRED`,
+`ZERO_BOOTSTRAP_TOKEN` (+`ZERO_ALLOW_MANUAL_PROVISIONING`),
+`ZERO_WORKTREE_ALLOWED_COMMANDS`, `ZERO_WORKTREE_ISOLATION_MODE`,
+`ZERO_OPENAI_API_KEY/_BASE_URL/_MODEL/_TIMEOUT_SECONDS`,
+`ZERO_ANTHROPIC_API_KEY/_BASE_URL/_MODEL/_TIMEOUT_SECONDS`,
+`ZERO_TASK_MAX_ATTEMPTS`, `ZERO_PROVIDER_MAX_ATTEMPTS`,
+`ZERO_TELEGRAM_WEBHOOK_SECRET`, `ZERO_DISCORD_APPLICATION_PUBLIC_KEY`,
+`ZERO_WORKERS_ENABLED`, `ZERO_SCHEDULER_/DELIVERY_/POLLING_INTERVAL_SECONDS`,
+`ZERO_COMBINED_TEST_COMMAND/_TIMEOUT_SECONDS`, `ZERO_WORKTREE_ROOT`.
+Fail-closed rules in `_enforce_fail_closed_rules()`; prod refuses dev DBs,
+missing keys, host-bounded execution.
+
+Secrets model is already right: bot tokens are **Fernet-encrypted project
+secrets** referenced by bindings (`api.py:741-773`;
+`interface_service.py:227-243`) — never env, never returned by API.
+
+## 4. Telegram runtime reality (what "go-live" costs today)
+
+1. Non-test env with `ZERO_WORKERS_ENABLED=1`.
+2. Store token: `POST /projects/{id}/secrets`.
+3. Binding: `POST /projects/{id}/interfaces`
+   `{platform:"telegram", chat_id, topic_id?, bot_token_ref, is_enabled}`.
+4. Link human: `POST /users/{id}/external-identities`
+   `{platform, external_id, external_username?}` → row written with
+   `verified=False`.
+5. **DEAD END**: verification exists only as
+   `identity_service.py:355-401 verify_external_identity()`; grep of
+   `api.py` shows **no route** calls it. Polling/webhook intake resolves
+   identities and denies unverified senders as `ignored_unlinked`
+   (`interface_service.py:450-474`). A new user cannot complete onboarding
+   through any documented interface. *(Reproduced — doc 02 R5.)*
+6. Webhook mode additionally requires `ZERO_TELEGRAM_WEBHOOK_SECRET` in the
+   same process (`interface_transport_service.py:69-95`), else 503.
+
+Access control beyond binding enable/disable: none. Gates are verified
+identity ∧ project membership ∧ permission (`interface_service.py:429-502`);
+static role matrix in `domain/authorization.py:102-121` (member holds
+`agent.manage`, so binding management is not owner-exclusive). No group
+allow-lists, no owner-only mode, no public-bot confirmation.
+
+Polling resilience note: `background_workers.py` skips bindings whose token
+fails to resolve **silently** (debug-level) — an onboarding trap with no
+surface feedback.
+
+## 5. Management affordances present vs required
+
+| Required (spec) | Present today |
+|---|---|
+| one-command installer | ✗ |
+| setup wizard | ✗ |
+| full TUI | ✗ |
+| local Web GUI | partial: operator web pages exist (`web/controller.py`: login/dashboard/users/projects/plans/executions/audit) but no wizard/providers/groups/usage/system pages, no setup-token auth model |
+| CLI for automation | partial: `serve|migrate|check-config|reconcile` only (`cli.py:36-68`) |
+| doctor / backup / restore / update / uninstall | ✗ (backup exists only as `BackupService` service-layer; recovery via `reconcile`) |
+| usage/cost views | REST only (`api.py` providers/usage) |
+| group & access policy UI | ✗ (no policy model at all) |
+
+## 6. CI/packaging
+
+`.github/workflows/ci.yml`: quality job (pip install -e .[dev], pytest 3.12,
+ruff, compileall) + release job (clean-tree gate → git-archive build →
+`scripts/validate_release_artifacts.py` → fresh venv wheel install → double
+migration → loopback health smoke). Good bones to reuse for installer
+artifact checksums and platform matrix extension.
+
+## 7. Tests covering this plan's blast radius
+
+`test_config.py` (fail-closed env), `test_smoke.py` (boot/health),
+`test_http_phase2.py` (identity/secrets endpoints), `test_interfaces.py` +
+`test_interface_remediation_red.py` (binding/intake flows),
+`test_providers.py`/`test_provider_streaming.py`/`test_real_provider_adapter.py`
+(provider contracts incl. retry/backoff added earlier),
+`test_observability.py` (backup/restore service), `test_release_validator.py`.
+New management code must add its own suites (doc 12) without weakening these.

+# 02 — Current Installation Failure Report (reproduced)
+
+Environment of reproduction: Windows 11, Python 3.11.x (also representative
+of a fresh Linux box without uv). Clone: `mhrsdev/zero-agent-dev-telegram@main`.
+
+| ID | Reproduced failure / trap | Evidence | Severity |
+|----|---------------------------|----------|----------|
+| R1 | **Documented prerequisite missing by default.** README step 1 requires `uv`; `Get-Command uv` → not found on a typical machine. A non-expert stalls before any Zero code runs. | shell output: `uv NOT INSTALLED -> README step 1 fails` | Blocker for target persona |
+| R2 | **Bare start hard-fails.** Running the documented final command without exporting env first prints `zero: configuration error: ZERO_ENV is required (one of: development, test, production).` and exits non-zero. No hint that a wizard/config file could exist. | R4 output | High (first-impression dead end) |
+| R3 | **No service lifecycle.** After boot there is no `status/stop/restart/logs`, no systemd unit, no autostart; closing the terminal kills Zero. `run_dev.sh` explicitly defers deployment ("not a production story"). | audit §2/§4 | High |
+| R4 | **Telegram onboarding is an undocumented REST gauntlet.** Go-live requires ≥8 correct JSON calls in exact order (user → project → membership → secret → external-identity → binding → enable → workers on) — none surfaced by README. | audit §4 checklist | High |
+| R5 | **Onboarding dead end (functional bug):** `POST /users/{id}/external-identities` always writes `verified=False`; verification exists only as `identity_service.verify_external_identity()` with **no HTTP route**. Every inbound Telegram message from that user is then denied (`ignored_unlinked`, `interface_service.py:450-474`). Live bot impossible via public interfaces even after the gauntlet. | grep `verify` in api.py → 0 route hits; intake denial path cited | **Blocker** |
+| R6 | **Silent polling skip:** bindings whose bot token cannot be resolved are skipped at debug level (`background_workers.py` token-resolve loop), so a typo'd/expired secret looks identical to "everything fine". | audit §4 note | Medium |
+| R7 | **No group/access policy.** Any verified member account can drive every feature in every chat the bot occupies; nothing distinguishes owner-only vs public; enabling a binding for a big group ≈ accidental public bot. | interface_service gates; authorization matrix | High (safety) |
+| R8 | **Management commands absent:** `zero --help` lists only serve/migrate/check-config/reconcile. No install/setup/status/doctor/logs/backup/update/uninstall. | R6 help output | High |
+| R9 | **Secrets UX:** tokens must be posted as JSON over HTTP to a dev server; no masked input flow, no rotation command, no export-without-secrets. | audit §4/§5 | Medium |
+
+## Root causes
+
+1. The project grew as an **engine**, not a product: excellent durable core,
+   zero "last mile" (install→wizard→operate).
+2. Configuration exists only as process-env + fail-closed validation; there is
+   no persistent typed config file to power a wizard/GUI.
+3. The Telegram path was built runtime-first; the **join** between a human's
+   platform identity and Telegram was left half-implemented (missing verify
+   surface), which alone blocks all live usage.
+
+## Required outcome (acceptance for this plan)
+
+A new user runs ONE curl|sh, answers wizard prompts (provider key, bot token,
+groups), watches a final test message arrive, and is done — no manual venv,
+no JSON REST gauntlet, no source edits; returning reconfiguration ≤3 minutes;
+every error prints a safe next action. Detailed acceptance in doc 13 (M9).

+# 03 — Zero Router Reuse Matrix
+
+Verdicts from full read of `Zero-router` (TS monorepo). Rule: reuse
+**validated concepts/schemas**, never the platform shell. Zero Dev Telegram
+already owns wire adapters + fallback/retry/cost in Python — port only what
+fills real gaps, integrated *around* `provider_service.py`, not beside it.
+
+## 1. Component map (what each package is)
+
+| Path | What it is | Framework |
+|---|---|---|
+| apps/gateway | Hono HTTP API `/v1/chat/completions`,`/v1/models`; auth/rate-limit/idempotency/audit middleware | Hono |
+| packages/registry | YAML→Zod catalog loader; indexed ModelRegistry; boot-time validation | TS/Zod |
+| packages/router | SmartRouter candidate filter + weighted score + alias routing | TS |
+| packages/engine | FailoverEngine, circuit/health tracker, credential rotation, rate limit (Redis optional) | TS |
+| packages/provider-sdk | adapter contract, PlanBuilder capability planning, token/cost math | TS |
+| packages/adapters/{openai-compatible,anthropic,google} | wire translation | TS |
+| packages/protocol / canonical | dialect translation; neutral types + capability enum | TS |
+| packages/crypto | envelope AES-256-GCM key wrapping; router API-key format | TS |
+| packages/store | Postgres multi-tenant store (orgs, keys, usage billing) | TS |
+| config/ | data-only YAML catalogs (13 providers, model files, aliases) | data |
+
+## 2. Capability verdicts
+
+### a. Provider/model registry & metadata — **REFACTOR+PORT** ✅ highest value
+`config/providers.yaml` (+`registry/src/schema.ts:86-112`) and
+`config/models/*.yaml` carry exactly what our wizard needs: base_url, auth
+kind, quirks, regions, retains_data; per-model context_window,
+max_output_tokens, capabilities[], speed tier, pricing inputs.
+Port as **pydantic models + two YAML files shipped inside `zero/manage`**;
+keep their "fail at boot on invalid catalog" philosophy and
+deprecation/reference checks (`registry.ts:69-109`). Indexed lookup pattern
+ports 1:1.
+
+### b. Health checking — **ARCHITECTURE-ONLY, port state machine** ⚙️
+No active pings anywhere; passive rolling-window breaker per
+`(provider,model)` with closed/open/half-open + TTFT
+(`engine/src/health.ts:10-49,62-185`). Port the ~200-line state machine into
+`zero/routing/health.py` keyed by `(provider_id, model)`; skip Redis variant
+(single-process product). Add one active probe we lack: wizard "test
+completion" already planned (spec §6).
+
+### c. Routing/fallback ordering — **REFACTOR+PORT core ideas** ⚙️
+Weighted scoring normalized within candidate set, mode presets,
+reliability-friendly defaults (`router/src/score.ts:39-95`); deterministic
+alias resolution; context-fit pre-checks; open-circuit exclusion;
+rejection tracing (`router/src/router.ts:123-340`). Failover ordering:
+credential-rotation before model substitution, terminal-vs-rotatable error
+classes, jittered backoff, first-event commit barrier for streams
+(`engine/src/failover.ts:54-231`). Integrate as a **candidate-selector that
+feeds our existing linear fallback chain** in `provider_service`
+(`send_request_with_fallback`), plus breaker gate + rejection reasons.
+Do NOT port first-event barrier yet (we expose no SSE to clients).
+
+### d. Cost estimation/pricing — **REFACTOR+PORT small pure module**
+Cache-aware `estimateCost()` with correct cache-read semantics
+(`provider-sdk/src/model.ts:59-74`) matches our TokenUsage classes; port math
+into existing pricing path (we already store 4 token classes) so estimates
+improve without schema change.
+
+### e. Credential handling — **SPLIT verdict**
+- PORT concept: error→credential-status classification
+  (invalid/exhausted/rate_limited/cooldown + retry_after)
+  (`engine/src/credentials.ts:110-163`) → drives cooldown before retry.
+- REJECT storage: Postgres/org-scoped store; keep Zero's Fernet secret
+  references. Optional later: envelope-crypto idea
+  (`crypto/src/envelope.ts:82-141`) if we ever need multi-key at-rest —
+  current single-key HKDF+Fernet is adequate for this product.
+
+### f. Capability detection — **DECLARATIVE ONLY today**
+Capabilities are declared in YAML and matched against request needs
+(`provider-sdk/src/plan.ts:79-146`); **no active tool-call/stream probes
+exist in Zero-router either.** Adopt declarative matching now; the wizard's
+active probe (spec §6 steps 7-8) is net-new work for us.
+
+## 3. Reject list (do not import/port)
+
+| Hazard | Evidence |
+|---|---|
+| Router API-key format + auth middleware (`zr_live_…`, SHA-256, scopes) | `crypto/src/api-key.ts:32-78`, `gateway/middleware/auth.ts:13-58` |
+| Multi-tenant org/team/billing store, ApiKey rpm/tpm, idempotency replay tables | `store/src/types.ts:3-113` |
+| PG migrations + row mappers; Redis client/scripts | `store/src/pg/*`, `engine/src/redis/*` |
+| Gateway HTTP app/pipeline (Hono context) | `apps/gateway/src/*` |
+
+## 4. Overlap guard (already exist in zero-agent-dev-telegram — do not duplicate)
+
+Wire translation, streaming, tool-message sanitation, usage normalization
+(`app/provider_adapter.py`), linear fallback + same-provider bounded retry +
+error classification + Decimal cost estimation + pricing registration
+(`app/provider_service.py`). Router-port integrates **upstream** of these:
+catalog → candidates → health/breaker gate → existing fallback chain.
+
+## 5. Final reuse tally
+
+| Verdict | Items |
+|---|---|
+| REFACTOR+PORT | provider/model YAML catalog (a); scoring/candidate selection + breaker-aware exclusion (c-core); breaker state machine (b); cost math refinement (d); credential-status classification (e-part) |
+| ARCHITECTURAL REFERENCE ONLY | Redis variants; PlanBuilder emulation rewrites (later, optional) |
+| REJECT | gateway app, org auth/API-keys, billing/multi-tenant store, PG/Redis infra, protocol/canonical packages (superseded by our canonical layer) |

+   Env vars remain supported and override file values at load (12-factor),
+   but every writer (wizard/TUI/GUI/CLI) goes through ConfigService.
+2. **One wizard engine.** `SetupService` exposes
+   `steps() / answer(step_id, value) / validate() / commit()`; the three UIs
+   render the same state machine (doc 06). No UI writes files directly.
+3. **Secrets stay in the engine's Fernet store.** Wizard collects values →
+   SecretRefService stores via `secret_service` and keeps only `sec_…`
+   references in config.yaml. Diagnostics/exports redact by construction.
+4. **Router-port is upstream of the chain.** Catalog+health+score select an
+   ordered candidate list; existing `send_request_with_fallback` executes it.
+   Circuit breaker state persists in SQLite (new table via migration 0029).
+5. **Access policy is enforced in intake**, pre-LLM: new
+   `AccessPolicyService.check(platform_event, binding, project)` runs before
+   identity resolution in `interface_service.process_inbound_event`; default
+   mode `owner_only`. Denials are logged with reason codes, respond with a
+   generic text, leak nothing.
+6. **Process ownership:** native install = systemd unit `zero.service`
+   running `zero-develop serve` as user `zero`; Docker = compose file with
+   the same command. `zero status/start/stop/logs` shells out to systemctl /
+   docker compose — no second supervisor.
+
+## New modules (paths)
+
+| Path | Purpose |
+|---|---|
+| `src/zero/manage/__init__.py` | package root |
+| `core/config.py` | schema v1 models, load/validate/migrate, atomic save (tmp+rename, fsync, lockfile), last-known-good copy |
+| `core/setup_machine.py` | step registry, durable draft state, transitions |
+| `core/policy.py` | GroupPolicy/AccessMode models + pure decision fn |
+| `routing/catalog.py` | providers.yaml/models.yaml pydantic port |
+| `routing/health.py` | breaker state machine (ported concept) |
+| `routing/score.py` | weighted candidate ordering (ported concept) |
+| `services/*.py` | table above (thin, testable, no I/O beyond adapters) |
+| `adapters/systemd.py`, `adapters/compose.py` | service manager backends |
+| `cli.py` | argparse `zero` entry (doc 07) |
+| `tui/app.py` | Textual app (doc 08) |
+| `web/admin_*.py` + `web/templates/admin/*` | GUI (doc 09) |
+| `branding.py` | logo/animation over real progress callbacks |
+| `scripts/install.sh` | POSIX installer (spec §1) |
+
+## Data additions
+
+- Migration **0029_routing_and_policy.sql**: `provider_health`,
+  `group_policies`, `usage_counters` (aggregates only — no message bodies),
+  `admin_users` (scrypt hashes), `setup_tokens`.
+- Config file locations (native): `/etc/zero/config.yaml` (root install) or
+  `$ZERO_HOME/config.yaml`; draft state `state/setup-draft.json` next to it;
+  last-known-good `config.last-good.yaml`.
+
+## Framework choices (no second runtime)
+
+Textual (TUI), Jinja2+htmx (GUI), PyYAML (catalog/config), stdlib
+hashlib.scrypt (admin passwords), secrets/token for setup tokens. Everything
+else already in dependencies.

+
+## Rules encoded in pydantic (`core/config.py`)
+
+- `schema_version` literal 1; unknown keys → error (strict).
+- Cross-field validation: `access.groups[].chat_id` uniqueness;
+  `routing.fallback_models ⊆ ∪ providers.models`; `websearch.provider_id`
+  must exist when enabled; `mode=public` requires `public_confirmed_at`;
+  every `*_ref` matches `^sec_[a-z0-9_]+$` and is checked resolvable at
+  commit time.
+- **Atomic writes:** write tmp in same dir → fsync → `os.replace`; lockfile
+  `.config.lock` (fcntl/msvcrt); on save, previous file copied to
+  `config.last-good.yaml`.
+- **Migrations:** `MIGRATIONS = {1: …}` map; loader upgrades older versions,
+  backing up original to `backups/config-v{n}-{ts}.yaml` first.
+- **Env override layer:** `ZERO_*` still honored by the engine; ConfigService
+  exposes `effective()` merge and reports any env-overridden key in wizard
+  ("managed elsewhere") so UIs never fight the environment.
+- **Export:** `export(include_secrets=False)` replaces refs with
+  `"__REDACTED__"`; diagnostics always use redacted form.
+
+## Migration of existing installs
+
+Importer reads current `ZERO_*` env (or systemd EnvironmentFile) → builds v1
+file; secrets stay where they are (engine store) and refs are created by
+looking up existing `secret_references` rows. Old-style-only users keep
+working: if no config.yaml exists, engine behaves exactly as today.

+# 06 — Setup State Machine (durable wizard core)
+
+One engine, three renderers (CLI prompts, TUI screens, GUI pages). State is

+"Save draft / Resume later" is inherent.
+

+
+## Semantics
+
+- **Transitions:** `next`, `back`, `skip`(optional only), `retry`,
+  `cancel`. `back` after side-effectful steps triggers the listed cleanup
+  handler before moving. `cancel` keeps draft, marks state `aborted`;
+  nothing committed.
+- **Never lose validated work:** each step stores
+  `data[step_id] = {value, validated_at}`; later failures cannot clear
+  earlier steps.
+- **Redaction:** every log line for steps 5/7/14 runs the engine's
+  `redact_sensitive_text`; values rendered masked (`tok_…abcd`).
+- **Idempotency:** re-running a ✱ probe is safe (getMe/test completion are
+  read-only; secret store upserts by name).
+- **Completion commit order:** validate → atomic write config.yaml → copy
+  last-good → ConfigService.reload() → engine env adapter applied → healthz
+  probe → mark `complete`.
+- **Resume:** `zero setup --resume` loads draft, jumps to `current_step`.
+
+## Machine-readable contract
+
+```python
+class Step(Protocol):
+    id: str; title: str; optional: bool
+    def render(self) -> StepInfo            # prompt/help/redacted-current
+    def validate(self, value) -> StepResult # errors[] + warnings[]
+    def apply(self, value) -> None          # side effects (✱)
+    def rollback(self) -> None
+```
+
+SetupService persists transitions and exposes the same API to TUI/GUI/CLI;
+UIs contain **zero** business logic.

+# 07 — CLI Design (`zero`)
+
+New console script `zero = zero.manage.cli:main` alongside `zero-develop`
+(engine entry kept for compatibility/CI). Built on argparse subparsers; every
+command supports `--json` (machine-readable) and `--config PATH`.
+Non-interactive flags enable full automation; interactive prompts only when
+stdin is a TTY and required input missing.
+
+## Commands
+
+| Command | Purpose | Key flags |
+|---|---|---|
+| `zero install` | one-command install (thin client over scripts/install.sh logic; on Linux delegates to it; validates post-conditions) | `--mode native\|docker`, `--unattended`, `--channel stable\|beta`, `--no-wizard`, `--base-url URL`, `--user NAME` |
+| `zero setup` | wizard (auto-resumes draft) | `--resume`, `--non-interactive --step id=value …`, `--from-env` (import ZERO_*), `--dry-run` |
+| `zero start/stop/restart/status` | service control via systemd/compose adapters | `--follow` (status), `--json` |
+| `zero logs [-f] [--since …] [--grep …] [--level …]` | journalctl/docker logs wrapper + secret redaction filter always-on | |
+| `zero doctor` | diagnostics (doc 14 spec) | `--json`, `--fix <issue-id>` (asks confirm unless `--yes`), `--bundle OUT.tar.gz` (preview with `--list-bundle`) |
+| `zero update [check\|apply]` | channel-aware update: preflight→backup→apply→health→auto-rollback | `--channel`, `--rollback-to TAG` |
+| `zero backup [create\|list\|verify FILE]` | wraps BackupService | `--include-secrets`(confirm), `--dest DIR`, `--retention N` |
+| `zero restore FILE` | preview → stage → commit | `--stage-only`, `--force`, `--confirm-hash H` |
+| `zero telegram add-bot` | masked token input, getMe verify, store ref | `--token-file -` (read stdin, never argv/history) |
+| `zero telegram groups discover\|add\|list\|enable\|disable\|remove` | group discovery via updates probe; stores verified policies | `--chat-id`, `--title`, `--default-agent`, `--yes` |
+| `zero access set-mode owner_only\|users\|groups\|users_and_groups\|public` | policy gate; `public` requires `--i-understand-public` | |
+| `zero providers add/list/test/remove` | provider wizard non-interactive form | `--protocol --base-url --key-file - --models a,b --priority N`; `test` runs auth+completion probes |
+| `zero models primary M [--fallback a,b]` | routing assignment validated against catalog | |
+| `zero agents list/set-default GROUP AGENT` | per-group agent/features | |
+| `zero usage summary [--today\|--days N] [--group --provider --model --agent --status] [--json]` | aggregates from counters (doc: usage) | `--csv` |
+| `zero limits set --daily-tokens N [--group ID …][--soft N]` | budgets incl. soft warn | |
+| `zero config show\|edit\|diff\|validate\|export [--redact]\|rollback` | last-known-good ops; `show` redacts by default | |
+| `zero secrets set NAME (--key-file -)\|rotate NAME\|delete NAME` | masked I/O; values never argv/env/echo | |
+| `zero websearch enable/disable/status` | gated by provider presence | |
+| `zero uninstall` | double-confirm; distinguishes app vs data; optional backup first | `--keep-data`\|`--purge-data`, `--remove-user` |
+
+## Cross-cutting rules
+
+- **Secrets:** accepted only via stdin/file/hidden prompt; never argv/env;
+  prompt uses getpass; process listings can't leak; logs pass through
+  `redact_sensitive_text`.
+- **Exit codes:** `0 ok · 1 operation failed · 2 usage/config error ·
+  3 needs-confirmation-missing · 4 unhealthy(doctor/update preflight)`.
+- **Automation example:**
+
+```bash
+curl -fsSL https://getzerodev.ai/install.sh | sh -s -- --unattended \
+  --channel stable --mode native --no-wizard
+printf '%s' "$BOT_TOKEN"   | zero telegram add-bot --token-file -
+printf '%s' "$OPENAI_KEY"  | zero providers add --id openai-primary \
+    --protocol openai_compatible \
+    --base-url https://api.openai.com/v1 --key-file - --models gpt-4o-mini
+zero access set-mode groups
+zero telegram groups add --chat-id -1001234567890 --title "Apollo Dev" --yes
+zero setup --non-interactive --step privacy.telemetry=false --step updates.channel=stable
+zero doctor && zero start && zero status --json
+```
+
+## Implementation notes
+
+Thin dispatch layer only: parses args → calls SetupService /
+TelegramAdminService / etc. No business logic, no direct file/DB writes.
+All long operations print phase lines from the real progress callbacks
+(branding module subscribes; no fake progress).

+# 08 — TUI Information Architecture (Textual)
+
+Full-screen, keyboard-first, SSH-friendly. One dependency: Textual (Python,
+maintained; built-in NO_COLOR handling, responsive layouts). ASCII fallbacks
+for every glyph; status = text+symbol+color (never color alone).
+
+## Global
+
+- Header tabs mirror nav; footer shows context keys.
+- Keys: `1..9,0` jump sections · `/` search/filter · `r` refresh ·
+  `?` shortcuts · `q` quit · `Ctrl+C` cancel dialog · `Enter` select ·
+  `Esc` back · `d` details drawer.
+- Dangerous actions open confirm modal typing verb (`type DELETE`).
+- Secrets render `tok_…last4` + `[reveal]` (explicit, per-view, auto-hide 10s).
+- Persian/Arabic: Textual handles bidi passably; technical tokens wrapped in
+  LTR-isolating spans (`\u2066…\u2069`); fonts degrade to ASCII box drawing.
+
+## Screens (nav order)
+
+1. **Overview** — service state (running/stopped/degraded + since), telegram
+   connection (mode/bot username/poll-or-webhook), groups count enabled,
+   provider health rows (provider/model/state/last-check), requests today,
+   tokens today, est. cost today (labeled estimate), recent errors (5),
+   version+channel+update-available, cpu/ram/disk bars, last backup age.
+2. **Telegram** — bot identity card, connection mode toggle info, webhook vs
+   polling state, token rotate action, test-message sender, event log tail.
+3. **Groups** — table: title/chat-id/kind/enabled/agent/features/limits;
+   actions add(discover wizard)/enable/disable/edit limits/remove; per-group
+   drilldown shows members policy + recent denials with reason codes.
+4. **Providers** — cards per provider: protocol/base-url/key(masked)+rotate/
+   models chips/health/fallback priority; add via embedded wizard steps;
+   `T` run test-completion now.
+5. **Models & Routing** — primary selector, fallback ordering (move up/down),
+   breaker states w/ manual reset, timeout/attempts fields.
+6. **Agents** — list agent types, per-group defaults matrix, feature gates.
+7. **Usage** — today/7d/30d pivot (group/provider/model/agent/status);
+   token+cost columns (estimate tag); soft/hard limit bars; CSV export path.
+8. **Logs** — streaming tail (pause `space`, filter `/`, level mask,
+   export `e`); always redacted view.
+9. **System** — service controls (start/stop/restart), autostart toggle,
+   ports, config paths, env-override report ("managed elsewhere" list).
+10. **Backups** — create now, schedule/retention form, archive table
+    (size/sha/verified), restore flow with preview + stage mode.
+11. **Updates** — current/channel switch, check now, release notes pane,
+    apply (runs preflight→backup→apply→health→rollback-on-fail job inline).
+12. **Settings** — privacy/telemetry, GUI bind address (+0.0.0.0 warning),
+    locale, editor for non-secret config fields (validated live).
+13. **Diagnostics** — `zero doctor` rendered as checklist with per-item
+    fix buttons where safe; JSON copy; support-bundle builder with file
+    preview + secret-scan result before export.
+
+## Responsive rules
+
+≥100 cols full tables; 80–99 collapse optional columns into detail drawer;
+<80 switches to stacked cards. All async ops show spinner + cancellable
+state; SSH drop → Textual suspend/restore preserves screen.

+# 09 — Local Web GUI Information Architecture
+
+Server-rendered Jinja2 + htmx (one ~10KB vendored js file), mounted by the
+same FastAPI app at `/admin`. Shares SetupService/etc. with TUI/CLI. Visual
+language: black/white minimal, light+dark via `prefers-color-scheme` +
+toggle; system font stack; no animations beyond 120ms fades.
+
+## Security defaults (non-negotiable)
+
+- Bind `127.0.0.1:PORT` (default 8787). Changing host requires editing
+  config + explicit `access.gui_bind_warning_acknowledged_at`; banner +
+  docs push SSH tunneling (`ssh -L 8787:127.0.0.1:8787 host`).
+- First run: one-time **setup token** printed by installer/CLI
+  (`zero status --json` shows it), valid 15 min / single use → forces admin
+  password creation (scrypt hash stored in `admin_users`; plaintext never).
+- Sessions: signed httponly samesite=strict cookie, 30-min idle + 12-h abs
+  expiry, server-side revocation list; login rate limit 5/min/IP with
+  exponential lockout; CSRF token per session on every mutating form/htmx
+  call.
+- Security headers: CSP (self only), X-Frame-Options deny, Referrer-Policy,
+  nosniff. All API responses redact secrets (refs only); audit every admin
+  mutation (`operation=admin.<action>`).
+
+## Pages
+
+| Route | Page | Contents/actions |
+|---|---|---|
+| /admin/login | Login | setup-token first-run → set password |
+| /admin | Dashboard | same cards as TUI Overview (status, telegram, groups, providers health, today usage/cost estimate, errors, version/update, host stats, last backup) |
+| /admin/wizard | Setup Wizard | step list w/ progress; per-step form identical to state machine; save-draft/resume buttons |
+| /admin/telegram | Bot | identity card, mode info, rotate token, send test message, recent events table |

+| /admin/routing | Models & Routing | primary select, fallback order, breaker states + reset, timeouts/attempts |
+| /admin/agents | Agents | agent types, group-default matrix, feature toggles |
+| /admin/usage | Usage & Cost | filters (range/group/provider/model/agent/status), totals + per-bucket tables, limit editors (soft/hard), CSV export; "estimates" label everywhere cost appears |
+| /admin/logs | Logs | tail w/ level filter/search, download redacted |
+| /admin/system | System Health | service controls, ports, paths, env-override report, disk/mem |
+| /admin/backups | Backup & Restore | create/schedule/retention; archive table(verify sha); restore wizard: preview→stage→commit |
+| /admin/updates | Updates | channel, check, notes, apply job progress, rollback button |
+| /admin/security | Security | sessions list+revoke-all, admin password change, GUI bind warning state, audit excerpt of admin actions |
+| /admin/settings | Settings | non-secret config fields w/ live validation; diff-before-save view |
+
+## Non-goals
+
+No multi-tenancy, no billing, no team management, no public exposure story —
+that is Zero Dev Web's territory. Single-instance local administration only.

+# 10 — Threat Model (STRIDE, product-scoped)
+
+Assets: bot token, provider API keys, Telegram chat ids/policy, admin
+password/session, config file, SQLite DB (usage/audit), host shell reach
+(worktree commands), reputation (public-bot accident).
+
+| # | Threat | Vector | Controls (existing → new) |
+|---|--------|--------|---------------------------|
+| S1 | Spoofed Telegram update triggers LLM/tools | forged webhook | ✅ signature verify before binding lookup; NEW: policy gate pre-LLM + generic denial text; replay window via update_id dedupe (exists) |
+| S2 | Spoofed admin | GUI access from LAN | NEW: loopback default, setup-token bootstrap, scrypt password, session hardening, rate limit, CSRF, audit |
+| T1 | Token/key tampering in config | local file write | NEW: 0600 perms, atomic replace+fsync, last-good + diff view; refs keep values out of file |
+| T2 | MITM provider calls | network | ✅ https enforced by URL validation; pin docs for proxies |
+| R1 | Secret disclosure in logs/diagnostics/exports | verbose errors, bundles | ✅ redact formatter+canary scan; NEW: export redact-by-default, bundle preview+scan gate, masked inputs everywhere |
+| R2 | Public bot accident → cost blowout | binding on big group | NEW: owner_only default; public requires typed confirmation; per-group budgets + soft/hard stops pre-request |
+| I1 | Prompt/response leakage via usage store | over-collection | NEW: counters only (ids+tokens+cost), never bodies; documented invariant + test asserting no message content columns written |
+| I2 | Config leaks via `/admin` JSON | naive serializer | NEW: pydantic `exclude` refs; golden test: no `sec_` values, no key material in any admin response snapshot |
+| D1 | DoS by group member spam | flood | NEW per-group rate limits + global daily budget checked before provider dispatch (429-style polite reply) |
+| D2 | Restart loop from bad creds | invalid token at boot | NEW: doctor preflight + engine keeps last-good config; service unit `Restart=on-failure` with `StartLimitIntervalSec`; wizard validates before commit |
+| E1 | Privilege escalation via command allowlist abuse (`rm /`, device writes) | run_command | ✅ bare-name allowlist, scrubbed env, argv (no shell); NEW hardline floor patterns; non-force cleanup already |
+| E2 | Path traversal in backup restore entries | malicious archive | ✅ staging DB verify; NEW zip-slip path check + manifest hash before stage |
+| E3 | CSRF/XSS on GUI | crafted link/page | NEW: CSRF token, CSP self-only, Jinja autoescape, no inline js |
+
+Residual risks accepted for v1: single-host SQLite concurrency envelope;
+physical/host-user compromise (out of scope); user-session mode absent
+(removes that whole attack class this release).

+# 11 — Migration Plan (existing installs → managed)
+
+## Personas
+
+A) **Fresh user** (target persona): nothing installed.
+B) **Existing dev** (clone + venv + env exports).
+C) **Existing server-ish** (clone + env file + manual process).
+
+## Path A — fresh
+`install.sh` → dedicated `zero` user (native) or compose project → venv at
+`/opt/zero` → `zero.service` enabled → `zero setup` wizard → done. No
+migration needed; engine DB created by `migrate` on first start.
+
+## Path B — existing clone/venv
+1. `pip install -e .` inside their existing venv (new `zero` script appears).
+2. `zero setup --from-env` importer: reads current `ZERO_*` from environment/
+   shell profile hint, writes `config.yaml` v1, creates secret refs for any
+   inline provider keys by storing them into the Fernet store and replacing
+   config values with refs. Engine env behavior unchanged (env still wins),
+   so nothing breaks if they keep exporting.
+3. Optional adoption of service management: `zero install --adopt`
+   generates unit pointing at THEIR venv path (no move required).
+
+Rollback: delete generated `config.yaml` (+refs left in store are inert);
+engine env-only behavior restored.
+
+## Path C — existing env-file servers
+Same as B plus: unit template uses `EnvironmentFile=` for any vars they keep
+outside config; ConfigService marks those keys "managed elsewhere" so UIs
+display but don't edit them.
+
+## Data migrations
+
+- Engine schema: one new migration set `0029_management.sql`
+  (provider_health, group_policies, usage_counters, admin_users,
+  setup_tokens). Additive only — no column changes to existing tables;
+  double-run idempotency covered by existing runner tests.
+- Config file: none existed before; importer is additive. Schema upgrades
+  handled by core/config MIGRATIONS with pre-copy backup.
+
+## Compatibility guarantees
+
+- `zero-develop …` commands/flags untouched (CI release smoke continues to
+  pass unmodified).
+- Env-var contract remains authoritative when present (documented precedence:
+  env > config.yaml > defaults). Wizard surfaces overrides instead of fighting them.
+- Telegram runtime protocols unchanged; new policy gate inserts before
+  identity resolution and defaults to permissive-today semantics
+  (`owner_only` enforced as: allow if sender == project owner's linked
+  identity; otherwise previous rules apply until owner edits policy) — no
+  existing working group breaks on upgrade.
+
+## Rollback strategy (global)
+
+Every milestone ships behind the branch; tags cut per milestone
+(`mgmt-m1`…). Native installs keep previous venv directory (`/opt/zero@prev`)
++ DB backup taken by update flow; `zero update --rollback-to <tag>` restores
+symlink + replays last-good config. Uninstall separates app vs data
+explicitly.
+
+## Deprecations
+
+None forced in v1. `.env.example` gains a header pointing to the wizard;
+README quick-start replaced by 60-second path while manual path moves to
+docs/manual-install.md.

+# 12 — Test Plan
+
+Principles: no weakened existing checks; every new feature ships with tests
+in the same commit; security controls get adversarial tests; platform claims
+only where CI actually runs.
+
+## 1. Unit (pytest, fast, in-memory)
+
+| Area | Cases |
+|---|---|
+| core/config | schema v1 accept/reject matrix; unknown key strictness; ref regex; cross-field rules (fallbacks ⊆ models, websearch provider exists, public needs confirm); atomic write crash simulation (tmp leftover ignored); lock contention; migration v0→v1 importer from env map; last-good rotation; export redaction |
+| core/policy | decision fn × mode × sender kinds (private/group/supergroup/forum/channel/migrated id/anonymous-admin) incl. denied reasons stable + non-leaking |
+| setup machine | happy path 20 steps; back-with-cleanup for ✱ steps; resume after kill at each step; cancel keeps draft; validation failure preserves prior steps; skip rules; commit order (validate→write→lastgood→reload→health) |
+| routing/catalog | catalog load fail-at-boot on bad YAML; alias resolution; capability match; context-fit filter |
+| routing/score+health | ordering determinism; breaker open excludes candidate; half-open probe path; cooldown expiry; rejection reasons recorded |
+| usage counters | aggregation math (tokens/cost estimate), soft vs hard threshold, per-group budget, no-content invariant (schema has no body columns — enforced by test reading sqlite_master) |
+| cli | arg parsing → service call mapping (mock services), exit-code table, secret-not-in-argv assertion by construction |
+| branding | NO_COLOR/CI/non-tty disable; narrow width fallback; copy override |
+
+## 2. Integration (real app via ASGI transport; tmp dirs)
+
+- Fresh install flow: `zero setup --non-interactive --from-env` end-to-end →
+  config written → engine boots with merged config → readyz ok.
+- Resume: kill draft mid-provider step; rerun resumes at same step with
+  values intact.
+- Invalid Telegram token: wizard step 5 fails w/ safe message; no secret
+  stored; retry succeeds with good token.
+- Groups: add two groups via discovery stub; enable/disable flips policy;
+  unauthorized chat_id gets generic denial + reason logged; owner passes.
+- Provider auth failure: wizard probe fails → save-unverified requires flag;
+  router marks provider degraded; fallback serves.
+- Rate limit path: mock 429 w/ Retry-After → backoff honored (sleep patched)
+  → breaker opens after threshold → next request skips provider (rejection
+  trace), recovers after cooldown.
+- Missing websearch: agent system note says unavailable; zero search calls
+  attempted (counter assert).
+- Backup/restore: create→verify→restore-stage→commit roundtrip incl. group
+  policies; zip-slip archive rejected.
+- Failed update rollback: fake target tag missing health → auto-rollback to
+  previous symlink + last-good config restored.
+- GUI: login w/ setup token→password; CSRF negative; session revoke;
+  redaction golden responses; rate-limit lockout.
+- TUI/GUI consistency: both render from SetupService.steps() snapshot
+  (contract test comparing exposed step ids/order).
+
+## 3. Security tests
+
+Command injection via argv is structurally impossible (no shell) — assert
+exec argv building never concatenates strings; log redaction fuzz over
+token-shaped strings; config file perms 0600 asserted post-save; public-bind
+warning flow; malicious provider response (huge/invalid JSON/tool-name
+mismatch) handled without crash/secret echo; Telegram update replay
+(duplicate update_id ignored); dependency scan job (pip-audit) advisory.
+
+## 4. Platform matrix (CI)
+
+ubuntu-22.04 x86_64 (native install script in container), debian-12,
+arm64 job (ubuntu-22.04-arm where available), docker-compose path,
+upgrade path test (previous tag → current, migrations double-run),
+Windows dev-only job (existing suite green; installer explicitly
+unsupported there and says so). Docs claim only what this matrix runs.
+
+## 5. UX acceptance (doc §19) automated skeleton
+
+Scripted harness `tests/ux_acceptance.py` driving CLI non-interactive mode
+through the 16-step persona journey asserting time budget (<10 min mocked-
+network) and "no secret in ps/logs" greps.
+
+## 6. Gates
+
+PR: unit+integration+lint+compileall. Nightly: platform matrix +
+pip-audit. Release: existing release job + new installer smoke inside
+fresh containers for each supported distro.

+# 13 — Ordered Implementation Plan (M0–M9)
+
+Small reviewable commits; each milestone ends green on the full suite and
+carries its own rollback note. Estimates are effort-units, not dates.
+
+## M0 — Groundwork (1)
+- Branch `feat/management-layer`; this plan committed under
+  `docs/management-layer-plan/`.
+- Add `zero = zero.manage.cli:main` console script (empty root command +
+  `--version`) so UX shape lands early.
+- **Accept:** `zero --version` works; existing suite untouched-green.
+- Rollback: drop branch.
+
+## M1 — Canonical config core (2)
+- `manage/core/config.py` schema v1 + validation + atomic save/lock +
+  last-good + env-override merge + importer (`--from-env`).
+- Migration `0029_management.sql` skeleton (admin_users, setup_tokens).
+- **Accept:** unit matrix doc12 §1-config; `zero config show|validate|
+  export --redact` functional.
+- Rollback: package unused by engine; delete files.
+
+## M2 — Setup state machine + CLI wizard/non-interactive (3)
+- Steps per doc 06 with draft persistence; Telegram getMe probe; provider
+  auth/completion probes via existing adapters; secret-ref storage through
+  engine SecretService.
+- Fix R5 blocker: expose identity verification (route
+  `POST /users/{id}/external-identities/verify` + wizard auto-verify on
+  first inbound message when policy owner matches) — unblocks live bots.
+- **Accept:** doc12 integration "fresh install flow", "resume",
+  "invalid token"; README quick-start swapped to wizard path.
+- Rollback: feature-flag `ZERO_MANAGE=0` hides commands.
+
+## M3 — Service management + installer (3)
+- `scripts/install.sh` (POSIX): URL var centralized; distro/arch/pm detect;
+  prereqs; native venv primary (/opt/zero, user `zero`), docker-compose
+  optional path; checksum verify from SHA256SUMS artifact; idempotent;
+  resume-state file; systemd unit + health check; launches `zero setup`.
+  Uninstall command per spec (confirm, app-vs-data, optional backup).
+- `zero start/stop/restart/status/logs` adapters (systemd/compose).
+- Branding module over real phase callbacks (NO_COLOR/CI/tty guards).
+- **Accept:** fresh-container runs for ubuntu/debian in CI; rerun idempotent;
+  failure mid-step resumes.
+- Rollback: script-only; `zero uninstall`.
+
+## M4 — Access policy + groups (3)
+- GroupPolicy model + `group_policies` table + intake gate in
+  interface_service (pre-LLM); modes incl. public-confirm; discovery flow
+  (bot added → updates probe lists candidate chats w/ titles → confirm);
+  per-group rate/token budgets enforced pre-dispatch; denial reason codes.
+- CLI: telegram groups*/access set-mode; silent-skip fix: unresolved token
+  logs warning + surfaces in doctor/status.
+- **Accept:** doc12 groups/unauthorized cases; existing interfaces tests
+  still green (default preserves current behavior until configured).
+- Rollback: gate disabled by config flag.
+
+## M5 — Routing port (catalog/health/score/breaker) (3)
+- YAML catalog ported (providers/models subset we support) shipped as
+  package data; pydantic models; boot validation.
+- HealthTracker state machine persisted in SQLite; scored candidates feed
+  existing fallback chain; rejection traces exposed at `/providers` detail
+  and TUI/GUI.
+- Cost math refinement (cache-aware) into estimate path.
+- **Accept:** doc12 routing cases; provider tests untouched-green.
+- Rollback: selector returns static chain when catalog absent.
+
+## M6 — Usage/cost + limits (2)
+- usage_counters aggregation on request completion (no bodies), filters,
+  soft/hard enforcement hook in access/routing path; CSV/JSON exports.
+- **Accept:** counters invariant test; limits block + polite message.
+
+## M7 — Diagnostics/doctor + backup/restore/update (3)
+- `zero doctor` checks per spec w/ --json/--fix/--bundle(secret-scanned,
+  preview); wraps BackupService for backup/list/verify/restore-stage;
+  update flow channels stable/beta: preflight→backup→apply(tag switch)→
+  health→auto-rollback; uninstall command.
+- **Accept:** doc12 backup/restore + failed-update-rollback cases.
+
+## M8 — TUI (Textual) (4)
+- Screens per doc 08 sharing services; redaction/masking components;
+  confirm modals; log tail streaming.
+- **Accept:** smoke-render test of each screen offline (Textual pilot
+  runner); keyboard map documented.
+
+## M9 — Local Web GUI (4)
+- /admin per doc 09: auth(setup-token→scrypt), sessions, CSRF, headers,
+  redaction goldens, audit admin actions; wizard + dashboard first, then
+  remaining pages.
+- **Accept:** GUI security cases; consistency contract test vs SetupService.
+
+## M10 — Hardening & docs & release (2)
+- pip-audit job; platform matrix CI (ubuntu/debian/arm64/compose/upgrade);
+  docs rewrite (60-second quick start, manual install, guides per spec §18
+  with fake tokens only); UX acceptance harness run recorded; cut
+  `mgmt-v1` tag + installer URL flip.
+- **Accept:** doc §19 checklist executed end-to-end on clean container.
+
+Total ≈ 28 effort-units. Dependencies: M2 needs M1; M3 independent after M1;
+M4 needs M1(+M2 for wizard UI of policies); M5 independent after M1;
+M6 after M4/M5; M7 after M3; M8/M9 after their services exist (M2+M4+M6).
+Critical path: M1→M2→M4→M6→M9.

-# Zero Develop — Audited Current-State Ledger
-
-This ledger reports behavior exercised in the current effective source tree. `VERIFIED` means
-verified by deterministic local tests or a named local probe; it does not mean production
-readiness or live external integration.
-
-| # | Milestone | State | Evidence boundary |
-|---|---|---|---|
-| 0 | Foundation ingestion and build readiness | VERIFIED | Foundation inventory and repository audit |
-| 1 | Repository bootstrap and executable skeleton | VERIFIED | Configuration, migrations, health, source, and installed-artifact gates |
-| 2 | Identity and project isolation | VERIFIED | Backend and authenticated HTTP isolation tests |
-| 3 | Authorization, secrets, tools, audit | PARTIAL | Auth, capability, and redaction tests; arbitrary in-process handler timeouts unsupported |
-| 4 | Plan lifecycle and Main Planner | PARTIAL | Lifecycle and rollback tests; concurrent transition hardening remains |
-| 5 | Main Worker and durable execution graph | PARTIAL | State, lease, retry, and recovery tests; claim/completion races remain |
-| 6 | Isolated branch/worktree execution | VERIFIED | Local Git/worktree and execution-boundary tests |
-| 7 | Dynamic Sub Agent Type lifecycle | PARTIAL | Deterministic lifecycle passes; concurrency and complete knowledge rollback remain |
-| 8 | Artifact store, memory, project RAG | VERIFIED | Deterministic local isolation and rebuild tests |
-| 9 | Retrieval, context, budgeting, compaction | VERIFIED | Deterministic context and recovery tests |
-| 10 | Provider adapters and usage reconciliation | PARTIAL | Fake adapter, replay, cancellation, and accounting tests; no billing truth |
-| 11 | Integration review and controlled merge | VERIFIED | Local deterministic integration, provenance, and lineage tests |
-| 12 | Primary website vertical slices | PARTIAL | ASGI tests; no browser/mobile/accessibility audit |
-| 13 | Telegram/Discord secondary adapters | PARTIAL | Canonical event and deterministic adapter tests; no live platform run |
-| 14 | Observability, recovery, security hardening | PARTIAL | Recovery, redaction, migration, and database-lineage tests; backup requires configured encryption authority |
-| 15 | End-to-end verification and controlled rollout | PARTIAL | Post-audit remediation suite (563 tests) and release gates; no production rollout rehearsal |
-
-## Current verification evidence
-
-- **563 tests passed, 16 platform-skipped** under `ZERO_ENV=test`. Reference-grounded additions (Anthropic adapter, LLM compaction summarizer, tool-round nudge) plus coherent retry lifecycle: retry-aware execution pausing, blocked-dependency revival, expired-lease terminal recording, worktree cleanup wired into recovery.
-- Python compilation, full scoped Ruff, and Ruff formatting checks pass for `src`, `tests`, and
-  `scripts`.
-- The effective schema contains **30** migration files (including `0027_remaining_project_lineage` and `0028_secret_key_versioning`). Migration IDs use complete filename stems;
-  numeric prefixes alone are not unique because three migrations begin with `0012`.
-- Direct SQL lineage tests cover both INSERT and UPDATE mismatch attempts for the identified
-  denormalized project-scoped tables.
-- The final staged wheel/sdist artifact gate passed: both artifacts contain exactly 30 migrations and
-  all required runtime modules; the sdist also contains the key scripts and lineage regressions.
-- The final installed wheel passed import, fresh migration/rerun/integrity, fail-closed configuration,
-  and loopback root/health/readiness probes.
-- Fresh, rerun, atomicity, concurrency, and populated-upgrade probes passed for the 30-migration set.
-
-## Deployment boundary
-
-Deployment remains a separate owner-authorized action and is blocked by the `PARTIAL` items above:
-live external adapters, browser/accessibility coverage, concurrency hardening, external persistence,
-and disaster-recovery rehearsal. Backup operations additionally require separately protected
-`ZERO_SECRET_KEY` authority.

Subject: [PATCH 7/8] feat(manage): wizard routes + capability probes + backup
 daemon + retry-after toasts + TUI screens + CI matrix

- Wizard: full GUI wizard driving shared SetupService (18 steps,
  back/skip/commit, CSRF, draft persistence)
- Capability probes: active tool-call and streaming detection per
  provider with TTL cache (capabilities.py), exposed via
  POST /admin/providers/{id}/test and CLI zero capabilities probe
- Backup daemon: scheduled background thread in engine lifespan
  (hourly/daily), overlap prevention via lockfile, stale-lock recovery,
  retention pruning, last-state tracking; CLI backup-daemon command
- Retry-After toasts: GUI toast() JS with countdown timer, dedup within
  15s window, probeProvider() integration on Providers page
- TUI: complete multi-screen set (Overview/Telegram/Groups/Providers/
  Usage/System/Backups/Diagnostics) driven by pure data layer
  (manage/tui/data.py); keyboard nav 1-8/r/q
- Usage page: /admin/usage with day/provider/model aggregation from
  provider_usage table
- CI: platform-matrix.yml (linux/arm64/debian12/windows-dev/
  installer-container/upgrade-path/security-audit)

+# Zero Dev Telegram — Full Production Readiness Implementation
+
+You are working on Zero Dev Telegram, an open-source AI development agent
+designed primarily for Telegram and small teams.
+
+Repository: https://github.com/mhrsdev/zero-agent-dev-telegram
+Branch: feat/management-layer (or main after merge)
+
+## Context
+
+Zero Dev Telegram currently has:
+- A durable control-plane core: identity, plans, executions, worktrees,
+  providers (OpenAI-compatible + Anthropic adapters), usage accounting,
+  audit log, access policy, capability probes, backup daemon, setup wizard
+  (CLI + GUI), TUI (Textual), local Web GUI (/admin)
+- 598 passing deterministic tests, ruff clean, compileall clean
+- A management layer (`src/zero/manage/`) with CLI, TUI, GUI sharing one
+  SetupService / ConfigService / AccessPolicyService
+
+What it does NOT have (the gaps this prompt must close):
+
+1. **Live integration qualification** — every external call is faked;
+   no real Telegram bot has ever been driven end-to-end in CI
+2. **PostgreSQL persistence backend** — SQLite-only today; no async
+   connection pooling for multi-worker deployments
+3. **Production sandbox executor** — `host_bounded` worktree execution is
+   refused in production because there is no container/chroot/namespace
+   isolation backend
+4. **User-session Telegram mode** — only Bot API is implemented
+5. **Client-facing streaming** — SSE parsing exists internally but no
+   endpoint streams tokens to clients
+6. **Interactive chat endpoint** — no REST/WebSocket route accepts a user
+   message and returns a model response inline (the current flow requires
+   plan→approve→execute→run-ready which is batch-oriented)
+7. **MCP / plugin extensibility** — no Model Context Protocol server or
+   plugin registry; tool set is fixed at 5 builtins
+8. **Subagent delegation** — the runtime runs tasks sequentially; no
+   isolated child contexts with their own provider/model/tool scope
+9. **Memory delta artifacts** — compaction reserves a field but never
+   writes accepted memory deltas back to knowledge records
+10. **LLM-driven task decomposition** — scheduler creates a single
+    "implementation" task per plan; no planner-adapter splits into
+    multi-step dependency graphs
+11. **Real tokenizer** — token counting uses bytes÷4 everywhere
+12. **Rate-limit-aware task retry** — tasks have attempt budgets but no
+    exponential backoff or Retry-After honoring between attempts
+
+---
+
+## Instructions
+
+Do NOT begin implementation immediately.
+
+First:
+1. Read the entire existing codebase (especially `docs/management-layer-plan/`,
+   `docs/CURRENT_STATE_LEDGER.md`, and every module under `src/zero/manage/`)
+2. Read the reference codebases at `C:\Users\SMN\Desktop\Zero\NEW\hermes-agent`
+   (full source) and `C:\Users\SMN\Desktop\Zero\NEW\claude-code` (docs/plugins)
+3. For each gap below, produce a design document covering: architecture,
+   data model changes, API surface, security considerations, test strategy,
+   migration path, rollback strategy, and acceptance criteria
+4. Commit design docs before writing any implementation code
+5. Implement in small, reviewable commits, one milestone at a time
+6. Every milestone must end green on the full suite (~600+ tests) with
+   ruff check, ruff format --check, and compileall all passing
+7. Do not present planned features as completed; do not disable checks to
+   make CI pass; do not store plaintext secrets
+
+---
+
+## GAP 1: Live Integration Qualification
+
+### Problem
+All Telegram/provider calls use deterministic fakes. The release validator
+explicitly states "no live provider or Telegram behavior has been verified."
+
+### Required implementation
+1. Create `tests/integration_live/` directory with pytest markers
+   `@pytest.mark.live_telegram` and `@pytest.mark.live_provider`
+2. These tests read credentials from environment variables:
+   - `LIVE_TELEGRAM_BOT_TOKEN` — a real bot token from BotFather
+   - `LIVE_TELEGRAM_CHAT_ID` — a test group chat id
+   - `LIVE_OPENAI_API_KEY` — a real OpenAI key with ≥$5 credit
+   - `LIVE_ANTHROPIC_API_KEY` — a real Anthropic key
+3. Tests must be skipped unless env vars are present AND
+   `ZERO_ENABLE_LIVE_TESTS=1` is explicitly set
+4. Write these live tests:
+   - `test_live_telegram_get_me.py`: call getMe via adapter, assert
+     non-empty username and bot flag
+   - `test_live_telegram_send_message.py`: send a test message to the
+     configured chat, assert message_id returned
+   - `test_live_telegram_poll.py`: run one poll_once cycle, assert either
+     empty result or valid update structure
+   - `test_live_openai_completion.py`: send minimal completion, assert
+     non-empty content and usage tokens > 0
+   - `test_live_anthropic_completion.py`: same for Anthropic adapter
+   - `test_live_provider_streaming.py`: verify SSE events arrive incrementally
+5. Create `.github/workflows/live-tests.yml` triggered by
+   `workflow_dispatch` only (never on push/PR); secrets injected from
+   GitHub repository secrets
+6. Document required secrets and how to obtain them in
+   `docs/LIVE_TESTING.md`
+
+### Acceptance criteria
+- All live tests pass when run manually with real credentials
+- CI workflow exists but does not run automatically without dispatch
+- Zero deterministic tests are affected
+
+---
+
+## GAP 2: PostgreSQL Persistence Backend
+
+### Problem
+SQLite works for single-process development but cannot handle concurrent
+writers, network access, or horizontal scaling needed for production teams.
+
+### Required implementation
+1. Add `asyncpg` or `psycopg[async]` to dependencies under `[pg]` extra
+2. Create `src/zero/persistence/pg_connection.py` mirroring the
+    Database interface (connect, transaction, ping)
+3. Create `src/zero/persistence/pg_migrations.py` using a numbered
+   migration approach compatible with existing SQL (translate dialect)
+4. Create `src/zero/persistence/pg_repositories/` implementing the same
+   protocol as each SQLite repository
+5. Config: accept `ZERO_DATABASE_URL=postgresql://...` when the `pg`
+   extra is installed; fail closed if not installed
+6. Docker Compose: add optional postgres service with healthcheck
+7. Migration runner: dual-dialect support — detect URL scheme and
+   delegate to appropriate backend
+8. Connection pooling: min 2, max 20, configurable via ZERO_PG_POOL_*
+
+### Acceptance criteria
+- All existing tests pass against SQLite (unchanged)
+- New integration tests pass against a disposable Postgres container
+- Repository protocol is identical; services don't know the backend
+- Fail-closed: production with pg:// URL and missing extra → clear error
+
+---
+
+## GAP 3: Production Sandbox Executor
+
+### Problem
+Worktree command execution (`host_bounded` mode) runs commands directly
+on the host with scrubbed env. This is adequate for trusted agents but
+not a hostile-code sandbox. Production refuses it entirely.
+
+### Required implementation
+Implement a pluggable executor protocol:
+
+```python
+class CommandExecutor(Protocol):
+    def execute(self, argv, cwd, timeout, output_limit) -> ExecResult: ...
+```
+
+Three implementations:
+
+1. **HostBoundedExecutor** (current behavior, dev/test only)
+2. **DockerExecutor**: runs commands inside a pinned Docker container
+   - Image: configurable via `ZERO_SANDBOX_IMAGE` (default `python:3.12-slim`)
+   - Resource limits: CPU quota, memory limit, pids limit, no network
+   - Volume mounts: worktree dir mounted read-write; nothing else
+   - Security opts: `no-new-privileges:true`, drop all caps except CHOWN/SETUID
+   - Non-root user inside container
+   - Timeout enforced by docker CLI `--time` + SIGKILL fallback
+3. **FirejailExecutor** (Linux-only): wraps commands in firejail with
+   private tmp, no network (--net=none), read-only system dirs
+
+Configuration:
+- `ZERO_SANDBOX_EXECUTOR = none | docker | firejail` (default: none)
+- When `none`, production refuses command execution (current behavior)
+- When `docker`, validate Docker socket availability at startup
+- When `firejail`, validate firejail binary presence at startup
+
+Wire into WorktreeService._validate_command / _run_bounded_process via
+the executor protocol so callers don't know the backend.
+
+Tests: unit tests with mocked subprocess/docker; integration tests with
+real Docker (skipif no Docker socket).
+
+### Acceptance criteria
+- Production can enable host_bounded execution when a sandbox executor
+  is configured
+- Commands cannot escape the worktree or access host filesystem/network
+- Capability report honestly reflects which executor is active
+
+---
+
+## GAP 4: User-Session Telegram Mode
+
+### Problem
+Only Bot API is supported. Some users want the agent to act as their
+personal Telegram account (reading/writing as themselves).
+
+### Required implementation
+1. Add Telethon or Pyrogram as an optional dependency under `[session]` extra
+2. Create `src/zero/adapters/user_session.py` implementing the same
+   NormalizedEvent intake protocol as telegram.py
+3. Configuration schema additions:
+   ```yaml
+   telegram:
+     mode: bot_api | user_session
+     session:
+       api_id: int
+       api_hash_ref: sec_…    # stored encrypted
+       phone_ref: sec_…        # stored encrypted
+       session_string_ref: sec_…  # encrypted session blob
+   ```
+4. Setup wizard step 4 gains a "User Session" branch that:
+   - Explains ToS implications and ban risk clearly
+   - Collects api_id/api_hash via masked input
+   - Initiates phone login → OTP prompt → optional 2FA password
+   - Stores session string encrypted; NEVER persists OTP codes
+   - Does NOT enable by default; explicit opt-in required
+5. Security requirements:
+   - Session string encrypted at rest (same Fernet profile as other secrets)
+   - OTP codes held in memory only, never written to disk or logs
+   - Rate limiting: max 30 messages/min outbound (anti-spam)
+   - Explicit disclaimer shown during setup
+6. Access policy applies identically (owner_only default)
+
+### Acceptance criteria
+- User-session mode disabled unless [session] extra installed AND
+  explicitly enabled in config
+- OTP/session material never appears in logs, audit, or diagnostics
+- Same access-policy gate as Bot API messages
+
+---
+
+## GAP 5: Client-Facing Streaming
+
+### Problem
+SSE parsing exists internally (provider_adapter) but no HTTP endpoint
+streams tokens to clients in real time.
+
+### Required implementation
+1. Add `GET /admin/executions/{eid}/stream` (SSE) endpoint:
+   - Content-Type: text/event-stream
+   - Emits `data: {"type":"text_delta","text":"…"}` per token
+   - Emits `data: {"type":"tool_call","name":"…","arguments":{…}}`
+   - Emits `data: {"type":"done","finish_reason":"stop"}` at end
+   - Heartbeat every 15s to keep connections alive through proxies
+2. Add `POST /admin/chat/{project_id}` (non-streaming alternative):
+   - Body: `{"message": "...", "agent_scope": "main_worker"}`
+   - Runs a single-turn completion through the runtime (no plan gate)
+   - Returns full response JSON
+3. Wire into AgentRuntime: expose a generator/callback interface that
+   yields CanonicalStreamEvents as they arrive (currently collected
+   internally by _collect_stream)
+4. GUI: add a simple chat panel on the dashboard using fetch() +
+   ReadableStream to render deltas progressively
+5. TUI: add a "Chat" screen that connects to the SSE endpoint and
+   renders tokens in a scrollable pane
+6. Security: both endpoints require admin auth; rate-limited; no raw
+   prompts/responses logged
+
+### Acceptance criteria
+- curl -N http://127.0.0.1:8000/admin/executions/X/stream shows incremental text
+- GUI chat panel renders tokens progressively (manual verification)
+- Existing non-streaming endpoints unchanged
+
+---
+
+## GAP 6: Interactive Chat Endpoint
+
+### Problem
+No way to send a message and get a model response without going through
+the full plan/approve/execute pipeline.
+
+### Required implementation
+Add `POST /admin/chat` endpoint that:
+1. Creates a ephemeral conversation context (no persistent plan)
+2. Builds a single-turn request with the system prompt + user message
+3. Dispatches through the provider chain (with fallback)
+4. Optionally executes tool calls up to max_tool_rounds (default 3)
+5. Returns JSON: `{"content": "...", "tool_calls_executed": [...],
+   "usage": {…}, "provider_request_id": "…"}`
+6. Usage recorded normally (accounting, cost estimation)
+7. Rate limited: configurable requests/minute (default 10)
+8. Requires admin auth (GUI session or bearer token)
+
+This enables interactive experimentation without polluting project state.
+
+---
+
+## GAP 7: MCP Server + Plugin Registry
+
+### Problem
+Tool set is fixed at 5 builtins. No way to extend without modifying source.
+
+### Required implementation
+Part A — MCP Client:
+1. Add `mcp` package as optional dependency under `[mcp]` extra
+2. Create `src/zero/manage/core/mcp_client.py`: connect to an MCP server
+   process (stdio), list available tools, invoke them, translate
+   results to/from ToolCallResult format
+3. Config schema addition:
+   ```yaml
+   mcp_servers:
+     - name: filesystem
+       command: ["npx", "-y", "@modelcontextprotocol/server-filesystem", "/tmp"]
+       enabled: true
+   ```
+4. On startup, connect to enabled MCP servers, discover tools, register
+   them in ToolService with `mcp_<server>_<tool>` naming convention
+5. Tool grants apply as usual (capability-based authorization)
+
+Part B — Plugin Registry:
+1. Create `src/zero/manage/plugins/` with discovery from two paths:
+   - `~/.zero/plugins/*.py` (user plugins)
+   - `/opt/zero/plugins/*.py` (system plugins)
+2. Each plugin file exports `register(manage_context)` where
+   `manage_context` provides: config, secret_store, tool_registry
+3. Load order: alphabetical within each dir; user overrides system
+4. Plugin loading failures logged but never crash the app
+
+### Acceptance criteria
+- An MCP filesystem server's tools appear alongside builtin tools
+- A sample plugin can add a custom tool callable by agents
+- Tools respect existing capability-grant authorization
+
+---
+
+## GAP 8: Subagent Delegation
+
+### Problem
+AgentRuntime processes tasks sequentially with no isolation between them.
+
+### Required implementation
+1. Add a `delegate` tool that agents can call mid-execution:
+   ```
+   delegate(objective, agent_type?, tools?, model?, context_budget?)
+   ```
+2. Implementation: spawns a new AgentRuntime.run_task() call with:
+   - A new synthetic task (child execution linked to parent)
+   - Its own agent type (defaults to caller's type)
+   - Isolated conversation history (fresh messages)
+   - Optional narrower tool set and smaller context budget
+   - Result returned to the parent as a tool result
+3. Depth limit: max nesting level 3 (parent → child → grandchild)
+4. Concurrency: delegated tasks count toward the agent type's
+   max_concurrent_instances limit
+5. Usage accounting: delegated requests tagged `is_whole_tree=False`;
+   aggregation sums whole-tree correctly
+6. Timeout: delegated task inherits parent's lease duration
+
+### Acceptance criteria
+- Parent agent delegates a subtask and receives the result inline
+- Delegated usage is tracked separately and summed correctly
+- Nesting depth limit prevents runaway recursion
+- Concurrent delegation respects instance limits
+
+---
+
+## GAP 9: Memory Delta Artifacts
+
+### Problem
+Compaction reserves `memory_delta_artifact_id` but never writes it.
+
+### Required implementation
+After successful compaction:
+1. Extract key decisions/facts from the compacted summary (the LLM
+   summarizer already produces structured sections)
+2. Parse sections into structured memory records:
+   - "Accepted decisions" → KnowledgeRecord(kind="decision")
+   - "Blockers or failures" → KnowledgeRecord(kind="failure")
+3. Store each record via AgentTypeService.add_knowledge()
+4. Set `memory_delta_artifact_id` on the CompactionRecord
+5. Make this opt-in per agent type: `memory_delta_enabled: bool`
+
+### Acceptance criteria
+- After compaction with LLM summarizer, knowledge records exist
+- Without LLM summarizer (fallback template), no records created
+- Field properly populated and queryable
+
+---
+
+## GAP 10: LLM-Driven Task Decomposition
+
+### Problem
+Scheduler always creates one "implementation" task regardless of plan complexity.
+
+### Required implementation
+1. Add a decomposition step in SchedulerService before creating execution:
+   - Send the approved plan revision content to the LLM with a prompt
+     asking for a JSON array of tasks with dependencies
+   - Schema: `[{"key": "auth", "objective": "...", "scope": [...],
+     "depends_on": []}, …]`
+   - Validate: ≤256 tasks, ≤1024 edges, acyclic, non-empty objectives
+   - Fall back to single-task on parse/validation failure
+2. Make this opt-in via config: `decomposition.enabled: bool`
+3. Cache decomposition results keyed by plan_revision_id (idempotent)
+4. Log the decomposition prompt/response pair as evidence artifacts
+
+### Acceptance criteria
+- Simple plans still produce single-task graphs (backward compatible)
+- Complex plans produce multi-node dependency graphs when enabled
+- Decomposition failure falls back gracefully to single-task
+
+---
+
+## GAP 11: Real Token Counting
+
+### Problem
+Token counting uses bytes÷4 heuristic everywhere.
+
+### Required implementation
+1. Add `tiktoken` as optional dependency under `[tokenizer]` extra
+2. Create `src/zero/manage/core/tokenizer.py`:
+   ```python
+   def count_tokens(text: str, model: str) -> int:
+       """Use tiktoken when available for known models; fall back to bytes÷4."""
+   ```
+3. Model→encoding mapping for common models (cl100k_base, o200k_base)
+4. Thread through to estimate_tokens(), compaction threshold checks,
+   context builder budget calculations, and usage cost estimation
+5. Graceful degradation: tiktoken not installed → bytes÷4 (current behavior)
+6. Cache encoding objects at module level (tiktoken is expensive to init)
+
+### Acceptance criteria
+- With tiktoken installed: accurate counts for GPT/Claude models
+- Without: current bytes÷4 heuristic (documented as approximate)
+- No behavioral change in tests that don't install tiktoken
+
+---
+
+## GAP 12: Rate-Limit-Aware Task Retry
+
+### Problem
+Tasks have attempt budgets but retries happen immediately with no delay.
+
+### Required implementation
+1. In the scheduler's requeue logic, track last_failure_at timestamp
+2. Compute delay before requeueing:
+   - Base delay: 60s * 2^(attempt_number - 1), capped at 3600s
+   - Jitter: uniform random [0, 0.5 * base_delay]
+   - If provider error contained Retry-After: honor it (capped 3600s)
+3. Store next_retry_at in task metadata (blocker_reason or new column)
+4. Scheduler skips requeueing until next_retry_at has passed
+5. Expose next_retry_at in GET /executions/{id}/tasks response
+
+### Acceptance criteria
+- Failed tasks wait exponentially longer between retries
+- Retry-After from provider rate limits is honored
+- Tasks stuck in permanent failure eventually exhaust budget and block
+
+---
+
