feat(webui): console authorization, RBAC, redaction, and audit model (Closes #633)

Phase 1 of the MCP Control Plane Web Console (#631) defines the model that
future gated writes must pass through, and enables none of them.

The read-only MVP (#426-#436) ships with no authentication; protection comes
from network placement alone (#435). That is adequate while every route is a
GET and inadequate the moment Phase 2 wires a write. This lands the authority
first, so no write can later be added without something to check it against.

webui/console_authz.py
  Identity sources (none / local-dev / access-proxy), a four-role matrix
  (viewer, operator, controller, admin), the privileged-action list, and a
  fail-closed authorize(). Every action maps to a task_key in
  task_capability_map, so the console cannot invent an authority the MCP layer
  does not already define. Roles are always server-side configuration, never a
  client assertion. Deny reasons are closed and enumerated; there is no
  implicit allow branch, and even an allow reports execution_enabled=false
  while ACTIVE_PHASE is 1.

webui/console_redaction.py
  One redaction pass for API payloads, rendered HTML, logs, and audit records.
  Reuses gitea_audit.redact as the shared authority rather than forking it,
  then adds console patterns for keychain references, credential assignments,
  PEM private-key blocks, and JWTs. Never raises: an unredactable value
  degrades to the placeholder rather than being emitted raw.

webui/console_audit.py
  Console-side audit records, which gitea_audit cannot supply: it records MCP
  mutations and carries no console actor, identity source, correlation id, or
  retention class, and an authorization denial is not a mutation at all. The
  two are additive and join on correlation.request_id. Records are redacted at
  build time, re-scanned at write time, and dropped rather than persisted if
  they still trip a detector. Retention is per-record; an unknown action is
  retained as privileged rather than standard.

webui/app.py
  Attaches an authorization block to the existing preview and attempt routes
  and records the decision. The terminal outcome is unchanged - gated_actions
  still fails closed for every action - so this cannot loosen anything. Adds
  GET /api/console/security-model publishing the three policies as JSON.

Probe authentication is deliberately declarative in this slice:
probe_auth_required() reports operator intent and no route consults it. The
documentation says so plainly and a regression test pins the not-enforced
status, so wiring it in Phase 2 is a deliberate change rather than a silent
one. An operator who sets the variable believing it protects a probe would be
worse off than one who knows it does not.

Tests: tests/test_webui_console_authz_audit.py - 75 passed, 93 subtests,
covering each acceptance criterion and each test the issue requires
(redaction units, default-deny for unauthenticated write stubs, audit record
creation for a simulated privileged preview).

# Web console authorization, RBAC, redaction, and audit model (#633)
**Phase 1. Read-only. This document defines the model that future console
writes must pass through; it enables none of them.**
The MVP deployment boundary ([`webui-deployment.md`](webui-deployment.md), #435)
documents internal-only serving and states plainly that MVP authentication is
*none* — protection comes from network placement. That is adequate while every
route is a GET, and inadequate the moment a gated write ships. This document
and the three modules it describes land **before** any write exists, so no
Phase 2 action can be added without an authority to check it against.
| Concern | Module |
|---------|--------|
| Identity, roles, authorization decision | `webui/console_authz.py` |
| Secret redaction for every surface | `webui/console_redaction.py` |
| Audit event schema, retention, sink | `webui/console_audit.py` |
| Machine-readable publication | `GET /api/console/security-model` |
Two invariants hold everywhere and are non-negotiable for every child of #631:
1. **No secrets reach the browser.** Credentials are resolved server-side and
redacted before any payload, page, log line, or audit record leaves.
2. **No ungated mutations.** Authorization is necessary but never sufficient;
execution stays disabled until the Phase 2 framework ships.
## Identity sources
The console performs *authorization*. Authentication is delegated, because a
console that mints its own sessions is a credential store, and this one must
not be.
| Source | Mode value | Authenticated | Shared host | Phase |
|--------|-----------|---------------|-------------|-------|
| None | `none` (default) | No — anonymous, capped at `viewer` | No | 1 |
| Local dev | `local-dev` / `local_dev` | Yes, **asserted not verified** | No | 1 |
| Access proxy | `access-proxy` / `access_proxy` | Yes, asserted by trusted proxy | Yes | 2 |
Selected by `WEBUI_AUTH_MODE`. An unrecognised value falls back to `none`
rather than erroring open.
**Access-proxy mode** reads the subject from the
`Cf-Access-Authenticated-User-Email` header, set by Cloudflare Access, WARP, or
an equivalent org portal that terminates authentication in front of the
console. If the header is absent the request did not traverse the proxy, so the
principal degrades to anonymous — it is never trusted by default.
The **role is always server-side configuration**, never a client assertion. It
comes from `WEBUI_ROLE_MAP`, a JSON object of subject → role:
```json
{"[email protected]": "operator", "[email protected]": "controller"}
```
An unmapped subject gets `viewer`. Malformed JSON yields an empty map, so
everyone gets `viewer` — a parse failure loses authority rather than granting
it.
Full SSO is explicitly a non-goal of this issue.
## Role matrix
Four roles, ordered least to most authority. Each role inherits every lower
role's actions; the table states the *minimum* rank required.
| Role | Authority |
|------|-----------|
| `viewer` | Read every console view. No write, ever, in any phase. |
| `operator` | Viewer, plus author-class work: claim, comment, open a PR. |
| `controller` | Operator, plus reviewer/merger-class decisions on a PR. |
| `admin` | Controller, plus destructive and policy-editing actions. |
`viewer` holds the empty write set by construction, and a test asserts it stays
empty.
## Privileged actions
Every console action maps to a `task_key` in `task_capability_map.py`, the same
single source of truth `gitea_resolve_task_capability` and the MCP tool gates
use. The console therefore cannot invent an authority the MCP layer does not
already define, and a regression test asserts each mapping matches.
| Action | Minimum role | Class | MCP permission | Confirm | Dual control | Break-glass | Phase |
|--------|--------------|-------|----------------|---------|--------------|-------------|-------|
| `claim_issue` | operator | gated_write | `gitea.issue.comment` | Yes | No | No | 2 |
| `comment_issue` | operator | gated_write | `gitea.issue.comment` | Yes | No | No | 2 |
| `create_issue` | operator | gated_write | `gitea.issue.create` | Yes | No | No | 2 |
| `comment_pr` | operator | gated_write | `gitea.pr.comment` | Yes | No | No | 2 |
| `create_pr` | operator | gated_write | `gitea.pr.create` | Yes | No | No | 2 |
| `review_pr` | controller | privileged | `gitea.pr.review` | Yes | No | No | 3 |
| `close_pr` | controller | privileged | `gitea.pr.close` | Yes | No | No | 3 |
| `merge_pr` | controller | privileged | `gitea.pr.merge` | Yes | **Yes** | **Yes** | 3 |
| `delete_branch` | admin | destructive | `gitea.branch.delete` | Yes | **Yes** | **Yes** | 3 |
**Dual control** means the acting principal may not be the sole authority: a
second distinct principal must confirm. **Break-glass** means the action is
expected to be unavailable in normal operation and its use is retained for two
years. Both are declared here and enforced by the Phase 2 framework; Phase 1
records the requirement on every decision so the framework cannot ship without
honouring it.
`delete_branch` is admin-only rather than controller because it is the one
irreversible action in the set.
### Authorization decision
`authorize(action_id, principal, for_execution=False)` returns a decision
record and **denies by default**. The deny reasons are closed and enumerated:
| Reason code | Meaning |
|-------------|---------|
| `unknown_action` | No such console action is registered. |
| `unauthenticated` | The principal is anonymous. |
| `unknown_role` | The role is not in the matrix. |
| `insufficient_role` | The role ranks below the action's minimum. |
| `phase_not_active` | Execution requested for an action whose phase is not open. |
| `allowed_preview_only` | Authorized — preview only, execution still disabled. |
There is no implicit allow branch. Even the allow result reports
`execution_enabled: false` while the console is in Phase 1, so no caller can
read an allow as permission to mutate.
## Secret redaction
One pass applies to **API payloads, rendered HTML, server logs, and audit
records** — the four surfaces where a credential could escape.
Redaction reuses `gitea_audit.redact` rather than forking it: that remains the
authority for secret-looking dict keys, `Authorization` material, and raw URLs.
The console layer then applies its own patterns:
Each rule below matches an *assignment form*: the named key, followed by `=` or
`:`, followed by the value. The keys are listed bare rather than spelled out as
complete assignments, because this document is itself scanned by
`scan_for_secrets` — writing the examples in full assignment form would make the
documentation trip the very detectors it documents.
| Rule | Catches (as an assignment) |
|------|----------------------------|
| `credential_assignment` | `token`, `password`, `passwd`, `secret`, `api_key`, `access_key`, `client_secret`, `private_key` |
| `credential_env_assignment` | `GITEA_TOKEN`, `GITEA_PASS`, `GITEA_PASSWORD` and suffixed variants |
| `keychain_reference` | `keychain:` entry references |
| `keychain_command` | macOS `security` keychain lookups (`find-generic-password`, `find-internet-password`) |
| `private_key_block` | PEM `BEGIN ... PRIVATE KEY` blocks |
| `json_web_token` | Three-segment `eyJ...` JWTs |
| `bearer_credential` | `Bearer` / `Basic` credentials |
Assignments keep the key and replace only the value, so an operator can still
see *what* was removed. Two behaviours are deliberate:
- **Fail closed.** A value that cannot be redacted becomes `[REDACTED]`
outright rather than being emitted raw. Redaction never raises.
- **Redact before persist.** `console_audit.build_event` redacts before
serialization, and `write_event` re-scans and **drops** any record that still
trips a detector. An unredacted record is never durable.
`scan_for_secrets` is the assertion helper: it returns the detector names still
matching a payload, and already-redacted hits are not findings. Tests use it to
prove the published policy, the security-model endpoint, and this document
itself carry no secret material.
## Audit event schema
`gitea_audit` records MCP-side *mutations* — which profile and Gitea user
performed which tool call. It has no console actor, no identity source, no
correlation identifier, and no retention class, and an authorization **denial**
is not a mutation, so it would never appear there at all. The console record is
additive, not a replacement: a Phase 2 action emits both, joined on
`correlation.request_id`.
Required fields, all asserted by tests so an edit cannot quietly drop one:
| Field | Content |
|-------|---------|
| `schema_version` | Currently `1`. |
| `event_id` | Unique per record. |
| `timestamp` | Timezone-aware ISO-8601, UTC. |
| `actor` | `subject`, `role`, `identity_source`, `authenticated`. |
| `action` | Console action id. |
| `action_class` | `gated_write`, `privileged`, `destructive`, or `unknown`. |
| `target` | `{kind, ref}`, e.g. `{"kind": "pr", "ref": "#123"}`. |
| `result` | `allowed`, `denied`, `previewed`, `failed`, `succeeded`. |
| `reason_code` | The authorization reason code above. |
| `correlation` | `request_id`, `session_id`, `mcp_task`, `mcp_permission`. |
| `retention` | `class`, `days`, `expires_at`. |
| `redacted` | Always `true`; records are redacted at build time. |
An unrecognised `result` degrades to `failed` rather than being stored
verbatim.
The sink is an append-only JSON Lines file named by
`WEBUI_CONSOLE_AUDIT_LOG`. It is **off by default**: with the variable unset,
events are still built — so callers and tests exercise the schema — but nothing
is written. Auditing never raises; a failed write returns `False` rather than
breaking the request it describes.
## Retention
| Class | Applies to | Default |
|-------|-----------|---------|
| `standard` | Routine gated writes | 90 days |
| `privileged` | `review_pr`, `close_pr`, and any unclassifiable action | 365 days |
| `break_glass` | `merge_pr`, `delete_branch` | 730 days |
Each record carries its own class, day count, and computed `expires_at`, so
retention is auditable per record rather than inferred from file age. An
**unknown action is retained as privileged, not standard** — for a safety
control the conservative direction is to keep the record longer.
Nothing in this module updates or deletes. Expiry is enforced by an
operator-run policy against `expires_at`, never by the console silently
rewriting its own history.
## Phase 2 integration
Phase 2 opens gated writes. It must reuse this model rather than introduce a
second one. The integration points are already wired and observable:
- **`GET /api/actions/{action_id}/preview`** attaches an `authorization` block
to the existing preview payload and records a `previewed` audit event.
- **`POST /api/actions/{action_id}/attempt`** attaches the same block and
records a `denied` event. The terminal outcome is unchanged — the MVP
registry in `webui/gated_actions.py` still fails closed for every action — so
Phase 1 cannot loosen anything. Phase 2 enforces on this same decision
instead of adding a parallel check.
- **`GET /api/console/security-model`** publishes the RBAC matrix, redaction
policy, and audit policy as JSON for operators and tests.
To open Phase 2, a child issue must: raise `ACTIVE_PHASE`, implement the
confirmation and dual-control flow the matrix already declares, emit a
`succeeded` or `failed` record alongside the `gitea_audit` mutation record, and
keep `viewer` unable to reach any of it. Turning on execution without the
confirmation flow contradicts a declared requirement and is a review failure,
not a shortcut.
## Local-dev mode
`WEBUI_AUTH_MODE=local-dev` reads the principal straight from the environment:
| Variable | Purpose |
|----------|---------|
| `WEBUI_DEV_SUBJECT` | Subject string; absent ⇒ anonymous |
| `WEBUI_DEV_ROLE` | One of `viewer`, `operator`, `controller`, `admin`; unrecognised ⇒ `viewer` |
**INSECURE — this mode is for loopback development only.** The subject and role
are *asserted by the developer running the process and verified by nothing*.
Anyone able to set an environment variable on the host is an `admin`, and
anyone able to reach the port inherits that principal. It provides no
authentication whatsoever; it exists so Phase 2 authorization paths can be
exercised without standing up a proxy.
Never enable local-dev mode on a non-loopback bind. Combining it with
`WEBUI_ALLOW_PUBLIC_BIND=1` or `WEBUI_ALLOW_REMOTE_BIND=1` publishes an
unauthenticated admin console.
For anything beyond a laptop use `access-proxy` mode behind Cloudflare Access,
WARP, or a VPN, as [`webui-deployment.md`](webui-deployment.md) requires.
### Probe authentication
`WEBUI_REQUIRE_PROBE_AUTH=1` declares that non-public probes should require an
authenticated principal. It is **opt-in**: the default is off so the MVP
`/health` contract is unchanged.
**This flag is declarative in Phase 1 and enforces nothing today.**
`console_authz.probe_auth_required()` reports the operator's intent, and no
route consults it — setting the variable does not currently change the
behaviour of `/health` or any other endpoint. It is published here so the Phase
2 action framework has a declared policy to honour rather than inventing a
second one, exactly as `ACTIVE_PHASE` gates execution while the matrix is
already declared. A regression test pins this "declared, not enforced" status,
so wiring it later is a deliberate change rather than a silent one.
Until Phase 2 wires it, probe protection rests on network placement alone, as
[`webui-deployment.md`](webui-deployment.md) (#435) states.
## Environment variables
| Variable | Default | Purpose |
|----------|---------|---------|
| `WEBUI_AUTH_MODE` | `none` | Identity source selection |
| `WEBUI_DEV_SUBJECT` | unset | Local-dev subject (insecure) |
| `WEBUI_DEV_ROLE` | `viewer` | Local-dev role (insecure) |
| `WEBUI_ROLE_MAP` | unset | JSON subject → role map |
| `WEBUI_REQUIRE_PROBE_AUTH` | unset | Require auth for non-public probes |
| `WEBUI_CONSOLE_AUDIT_LOG` | unset | Append-only audit sink path |
All are read server-side only. None is ever rendered into a page or returned by
an API.
## Non-goals
- No full SSO product; authentication stays delegated to the proxy.
- No browser-initiated merges or approvals in any phase covered here.
- No tokens in the frontend, in browser storage, or in committed config.

not-enforced status here means wiring it later is a deliberate change
that updates this test and the documentation together, rather than a
silent behaviour shift. The documentation must say so plainly, because
an operator who sets the variable believing it protects a probe is
worse off than one who knows it does not.

"""Console audit event schema, retention, and append-only sink (#633).
``gitea_audit`` records MCP-side *mutations*: which profile and Gitea user
performed which tool call. It carries no console actor, no identity source, no
correlation identifier, and no retention class, so it cannot answer the
question #633 exists to answer — *who sat at the console, what did they
attempt, and was it authorized?* An authorization denial is not a mutation and
would never appear there at all.
This module adds the console-side record. It does not replace ``gitea_audit``:
when a Phase 2 action eventually reaches MCP, both fire, correlated by
``correlation.request_id``.
Design constraints:
- **Redact before persist.** Every record passes through
``webui.console_redaction.redact_payload`` before serialization, so an
unredacted field is never durable.
- **Append-only.** Records are appended as JSON lines. Nothing here updates or
deletes; retention is metadata on each record, enforced by an operator-run
policy, never by silent rewriting.
- **Never raises.** Auditing must not break the request it describes. A failed
write returns ``False``.
- **Off by default.** With ``WEBUI_CONSOLE_AUDIT_LOG`` unset, events are still
*built* (so callers and tests see the schema) but nothing is written.
A record looks like this (synthetic values):
{"schema_version": 1, "event_id": "evt-0001",
"timestamp": "2026-07-22T10:16:42+00:00",

"""Console authorization and RBAC model (#633, Phase 1).
The read-only MVP (#426#436) ships with no authentication: protection comes
from network placement alone (#435). That is adequate while every route is a
GET, and inadequate the moment Phase 2 wires a gated write. This module is the
authorization model those writes must go through, landed *before* any of them
exists so no write can be added without an authority to check against.
Phase 1 scope is the model itself: identity resolution, the role matrix, the
privileged-action list, and a fail-closed :func:`authorize`. It deliberately
does **not** enable any write. ``webui.gated_actions`` stays globally disabled,
so an allow decision here is necessary but never sufficient.
Two invariants hold for every caller:
- **Default deny.** An unrecognised action, an unknown role, or an absent
principal denies. There is no implicit allow branch and no "unless" clause.
- **Authorization is not execution.** :func:`authorize` returns a decision
record. It never calls MCP, never mutates, and never consults credentials.

"""Secret redaction policy for every console surface (#633).
The MVP already redacts MCP-side mutation records through ``gitea_audit``.
This module is the console-facing policy: one redaction pass applied to API
payloads, rendered HTML, log lines, and audit records *before* they leave the
server or reach persistent storage.
Design constraints:
- **Reuse, never fork.** ``gitea_audit.redact`` remains the authority for
secret-looking dict keys, ``Authorization`` material, and raw URLs. This
module runs that pass first and then applies console-specific patterns for
keychain references, key/value assignments, private-key blocks, and JWTs.
- **Never raises.** Redaction is a safety control; a malformed payload must
degrade to a redacted placeholder rather than propagate an exception.
- **Redact before persist.** ``webui.console_audit`` calls this module before
writing, so an unredacted record is never durable.
