Owner-approved console item (g), spec §7.4.

  • Domain (collaborators.rs): Pro owners invite up to 10 people per app by email. The email is allowlisted during the closed beta (no invite codes — owner decision), gets the spec's notification email, and is linked when it signs in. Removal takes effect on the next call. Usage is charged to the owner. A downgrade hides collaborator access without deleting the rows.
  • MCP: add_collaborator, remove_collaborator, list_collaborators (owner-only). Collaborators see shared apps in list_apps with role: collaborator. Tools reference regenerated.
  • One seam: visible_app replaces owned_app everywhere; each endpoint states its rule.
    • Collaborators may: read the app, code, logs and errors, triage errors, commit, roll back (MCP), list secret names.
    • Owner-only: visibility, rename, delete, secret writes, collaborator management, and D1 entirely (v1).
    • Strangers get 404. The logs SSE stream rechecks the role each tick, so removing someone ends their stream.
  • Console: Settings → Collaborators (invite, list with joined/pending, remove with confirm; Free owners see it disabled with a Pro badge). Collaborators see Settings, Secrets and D1 without write controls (read-only notices); triage stays available. Registered in actions/collaborators.ts.

Live (outer:2fbc96e): on a throwaway app, invited a test user from the console. As that user (own session): the app is listed as collaborator; app, code tree and errors 200; visibility, rename, secret write, delete, collaborator management → 403 with a plain explanation; D1 → 403. After removal → 404. Test app, user and sessions deleted. 569 tests; build green.

CodeRabbit is out of free reviews; merging on green CI plus the live check.

Summary by CodeRabbit

  • New Features
    • Pro app owners can invite, view, and remove up to 10 collaborators per app.
    • Collaborators can access shared apps, view app data and secrets, review activity, and triage errors. Shared apps are labeled in the Console.
    • The Console shows collaborator status and provides owner controls for invitations and removals.
  • Access Controls
    • Collaborators can make code changes and roll back, while app settings, secrets, database editing, and collaborator management remain owner-only.
  • Documentation
    • Added reference information for collaborator management tools.

Domain (crates/outer/src/collaborators.rs): add/remove/list/role for
app_collaborator, Pro-owner gate, 10/app cap, closed-beta allowlisting,
spec-worded invite email, userId linking on invite + at sign-in.

Permissions: visible_app/owner_app across MCP tools; collaborators may
use reads, commit, rollback, share, list_secrets; owner-only stays
owner-only (forbidden). Commits charge the owner's quota. Action log
records collaborator rows; NULL/NULL credentials read 'Console'.

MCP: add_collaborator/remove_collaborator/list_collaborators in
registry (hints classified) + regenerated web/docs/reference/tools.md.

Console: GET/POST /api/console/apps/{slug}/collaborators{,/remove},
role-aware reads (apps, app, actions, metrics, logs, errors,
secrets), Settings collaborators card with invite/remove + Pro
treatment, Shared rail/sidebar markers, actions/collaborators.ts
registry.
…red, UI read-only

MCP: rename_app gates on owner_app (forbidden for collaborators);
resolve/ignore/reopen gate on visible_app (collaborators may triage:
spec 7.4 owner-only is membership/visibility/secrets/destructive,
triage is operational like commit/rollback). Observe reads unchanged.

Console: rename endpoint uses owner_mutation_app; error detail, triage
and logs stream use visible_app; the follow tick rechecks the caller
role every tick. Collaborator audit rows carry the new duration_ms.

UI: Secrets add/replace/remove and all D1 write controls hide for
collaborators (read-only notice instead); triage buttons stay.

Tests: MCP rename forbidden + collaborator triage round-trip;
console rename 403, collaborator triage/observe 200, stranger 404.
console_account routes merge alongside collaborators; registry 38,
anon tools/list 38, authed 36 (35/33 base + 3 collaborator tools).
Regenerate tools.md (delete_account). Fix duplicated settings case
from the loadersFor merge.

Walkthrough

This change adds Pro-gated app collaborators with invitation, removal, account linking, and role-based access across Console and MCP. Collaborators can use permitted app operations, while owner-only operations remain restricted. Console adds collaborator management and read-only controls for Secrets and D1 data.

Merge Risk: Low · up to 2fbc9

Collaborators who open D1 in the console will see an error instead of the read-only view the UI describes, and invite emails will show stray asterisks. Neither affects owners or data safety, so the change is mergeable with these small follow-ups.

Rebase onto origin/main (#53): owned_app is gone, visible_app is the
seam. Move the owner check into console_data/mod.rs as owner_app with a
panel noun; D1 calls it with 'this database', console_app (R2/DO) with
'this data'. Console hides R2/DO nav for non-owners and shows the same
owner-only empty state on their routes. Test: collaborator 403 on
r2/list and do/classes, stranger 404.

* Console data panels (R2 + Durable Objects): server side

New module http/console_data (r2.rs, durable.rs, shared mod.rs) under
/api/console/apps/{slug}/data/... with the console guard (session,
same-origin, owner-scoped 404). R2: S3 reads with per-request scoped
creds on fleets/{slug}/r2/<bucket>/, writes/deletes via celld r2 put/delete;
bucket allowlist from the deployed manifest (raw_metadata.bindings),
local dist/wrangler.json fallback. DO: read-only class/instance list via
celld cell list (reserved classes skipped) + best-effort ?read=1 probe.
Writes audited as r2_put/r2_delete with both ids NULL (client Console);
client_label maps both-NULL to Console. Port of Noite r2/durable
backends @ 58a977a (encode/decode/validators verbatim).

* Console data panels (R2 + Durable Objects): UI + docs

Registered action modules actions/data-r2 + data-do (ConsoleAction
registries; components call run()), R2 browser + DO viewer islands under
data/, sidebar Data entries real (D1 stays Soon), daisyUI modal confirms,
docs 'Browse your data in the console' section. Ports of Noite
lib/storage/{r2,do,shared} @ 58a977a adapted to Outer routing and the
console conventions. URL state dropped (island-local), probes run on
selection, island fetches use watch.once.

* Console data panels: errorMessage lives in data/shared, views import from there

actions/types.ts is gone (ConsoleAction comes from actions/settings.ts
like the other registries, fetch goes through actions/http.ts), so the
three views that used its errorMessage helper import it from the merged
data/shared.tsx instead.

* Rebase onto main (#50-#52): duration_ms audits, dash-key refusal, merge fixes

- record_console gained duration_ms (rename_app #50): pass 0 at the six
  console-data audit sites (r2_put, r2_delete, d1_write, d1_delete_rows).
- Option injection: r2_key_ok refuses a leading '-' (keys travel
  positionally to celld r2 put/delete; 0.6.2 honors no '--' separator),
  so put/delete/file/raw/list answer 400 with a user_message before any
  credential or celld call. Manifest bucket_name / DO class leading-dash
  skips and built-config rejections already existed; covered by tests.
- Merge resolutions: keep S3 list_delimited_page/head + slug-scope
  delete_prefix doc; keep account + R2/DO titles, icons and view arms.
- Tests: dash-key unit test; delete rejects '-evil'; file 400 carries
  error/user_message; DO instances?class=-evil is 400.

* data-r2-do: header-sign LIST, friendly R2 user_message

R2 answers 501 NotImplemented when the session token rides the
presigned ListObjectsV2 query string, while object GET/HEAD presigns
work. Both list paths now sign a SigV4 Authorization header (hmac +
sha2 + hex, already in tree) and send the token as the signed
x-amz-security-token header; the query carries no token. Object
presigns stay as they are.

R2 backend failures now show a friendly user_message (detail stays in
message): raw S3 XML no longer reaches the UI.

* data panels: one shared owner check (R2/DO owner-only like D1)

Rebase onto origin/main (#53): owned_app is gone, visible_app is the
seam. Move the owner check into console_data/mod.rs as owner_app with a
panel noun; D1 calls it with 'this database', console_app (R2/DO) with
'this data'. Console hides R2/DO nav for non-owners and shows the same
owner-only empty state on their routes. Test: collaborator 403 on
r2/list and do/classes, stranger 404.

* Console DO: empty-state copy uses code elements, not literal backticks

* Console R2: empty-state copy uses code elements
