Ruben Fiszel 89a7a37776 fix(backend): authorize single-job read endpoints by job/flow visibility (#9416)
* fix(backend): authorize single-job read endpoints by job/flow visibility

* feat(jobs): share read links + cached access checks for run visibility

- Cache the job read-access RLS probe (size-bounded LRU keyed by the caller's
  authz-relevant identity + job id; no TTL since job-side inputs are immutable).
- Inherit visibility along the full parent_job chain so any flow you can see lets
  you read its (deeply nested) steps.
- Share read links: GET /jobs/job_view_token/{id} mints a stateless
  HMAC(workspace_key, job_id) token (only if the caller can read the job); the
  token grants an authenticated member read of that job and its flow subtree via a
  ?view_token query param or X-View-Token header. Run page gains a Share button and
  honors a ?view_token link.
- Denied-but-existing reads now return 403 with guidance to request a share link
  (vs 404 for non-existent), and the run page renders that case with instructions.

* fix(jobs): address PR review — scope-tag check on mint, constant-time view-token verify

- P1 (Codex): get_job_view_token now enforces the caller's if_jobs:filter_tags
  scope before minting, so a tag-scoped token can't mint a transferable link for a
  job outside its tags. Adds a scoped-token regression test (allowed + denied).
- Constant-time view-token verification (HmacSha256::verify_slice) instead of
  comparing hex strings (Claude/Pi nit).
- get_completed_job_result: an authed reader passing an invalid suspended-secret
  triple now falls through to the normal visibility gate instead of erroring out
  (Claude nit); unauthenticated callers still rejected.
- Length-prefix the read-access cache key fields so no input values can collide.

* docs(api): add job_view_token to openapi spec; use generated client in run page

Addresses Codex review nit: the new GET /jobs/job_view_token/{id} endpoint was
missing from openapi.yaml (the source the frontend client is generated from). Adds
the path + operationId getJobViewToken, and switches the run page's Share button
from a raw fetch to JobService.getJobViewToken.

* fix(frontend): carry view_token on share-link downloads

Addresses Codex review: download actions bypass the request interceptor that adds
X-View-Token (downloadViaClient uses raw fetch; cookie-mode downloads use plain
hrefs), so a share-link viewer got 403 downloading logs/results/args. Append the
view_token query param to the job download paths (result/logs/args/flow-all-logs)
via a new appendViewToken() helper, covering both client-fetch and href modes.

* fix(jobs): enforce tag scope in require_job_read_access (view-token use side)

Addresses Codex P1: the view_token use-side bypassed if_jobs:filter_tags on
handlers that don't tag-filter their data query (result_by_id,
get_flow_job_debug_info, get_otel_traces) — a tag-scoped token could use someone
else's valid share token to read out-of-scope job data. Move the tag-scope check
into require_job_read_access (runs before any created_by/view_token/RLS grant), so
it applies uniformly to every gated handler; removes the now-redundant explicit
check in get_job_view_token. Adds a use-side regression test (scoped token + valid
out-of-scope view_token denied on otel/result_by_id; in-scope still allowed).

* fix(frontend): include workspace in share read link

Addresses Codex P1: the copied share URL omitted the workspace. The token is
signed with the run's workspace key and the logged layout only switches
$workspaceStore when the URL carries workspace=, so a recipient whose persisted
active workspace differs would open the link against the wrong workspace and the
token would fail validation. Pin workspace= alongside view_token in the link.

* fix(jobs): authorize get_result_maybe get_started branch for queued jobs

Addresses Codex P1: get_completed_job_result_maybe only gated when a completed row
existed; with ?get_started=true a non-reader reached the fallback branch and got
started:true for a running private job. Now fetches created_by and authorizes
(created_by/view_token/RLS, or anonymous for unauth) before disclosing
running-state; a non-existent job still returns started:false (leaks nothing).
Adds a regression test with a queued (no completed row) private job.
