Replace task eligibility with canonical project authorization - #397
Merged
Conversation
📝 WalkthroughWalkthroughThe change replaces legacy task eligibility with exact-project grant authorization for task claim, start, and work-context operations. It adds task authority contracts, audit events, transaction-bound commands, migration updates, retired public routes, focused race tests, and updated plans and documentation.

Merge Risk: 🟡 Moderate · up to Retrying a task command after a retryable authorization-storage failure needs verification that it produces one transition and one evidence record.

In `@backend/app/api/deps/authorization.py`:
- Line 142: Update both task handlers, PreparedTaskAuthorization.consume and
restage_denial, to catch AuthorizationEvidenceUnavailable alongside
SQLAlchemyError in their exception handling. Preserve the existing
task_authority_unavailable 503 response path so exceptions translated by
_stage_decision are handled consistently.
In `@backend/app/modules/authorization/task_authorization.py`:
- Around line 35-38: Update get_task_commands and its service-actor denial path
so every rejected task authorization records a canonical AUTH
AuthorizationDenied decision, including the resource, before raising
TaskAuthorityDenied; preserve the existing human-context and actor-profile
validation behavior.

Intent and bounded change
Replace self-activated task eligibility with canonical project authority.
Identity and token roles must not grant contributor work access.
Scope, alternatives, acceptance criteria and proof ownership are in the
change record.
Implementation
/workers/me/profile, eligibility activation/bridge code and the old public JSON-packet submission POST. Preserve retained data and submission reads.Current verification

34600325950at1c004f1fpassed six backend lanes but failed the claim-first grant-revocation race in shared foundations B. Its duplicate observer retained a transaction-scoped PostgreSQL activity snapshot.97cb8683removes that duplicate and routes every consumer to the existing AUTOCOMMIT AUTH observer. Race assertions, timeouts and the 5,000-poll bound are unchanged. Exact-head PostgreSQL verification passed five cases in 70.73 seconds: fresh/cached observer discrimination, both grant-revocation orderings, and submission-context lock serialization. Isolated database/role cleanup passed. A broader local attempt timed out at its existing 300-second budget and is not counted as passing evidence. Fresh full hosted verification subsequently passed.The successful prior full run took 1,209.98 seconds: the advisory eight-minute timing target was not met. No timing claim is inferred from functional success.
The tracing regression independently fails when the concurrency setting is removed, even without its configuration assertion. The actor-resolution regression independently detects removed rollback calls.
Ruff, diff checks, Markdown links, stale wording and Commitrail checks pass. No local spreadsheet exports exist in this worktree.
Earlier percentages measured without greenlet-aware tracing are non-certifying;
their test outcomes are distinct from coverage measurement. Full tests remain
hosted, not inferred from partial local runs.
Reviews and external findings

Service/action denial matrix and foreign-actor/old-guard probes passed.f95d2271; unchanged runtime owners, public ports, lock order and boundaries.f95d2271; documentation replay passed atf536c6b6. Latest delta changes tests only.97cb8683, zero findings. Exact-head PostgreSQL proof plus all 5,819 hosted nodes complete; fresh/cached observer regression discriminates the removed defect and both real race orderings pass.97cb8683, zero findings. Independently inspected bound hosted artifacts and seven raw coverage databases; zero skipped/deselected tests or attribution anomalies. No test nodes, parameters, assertions, timeouts or lane assignments changed in the observer repair.Combined tracks above were not independently staffed within each pair.
Prior reviews are not relabeled as newer-head reviews; summaries mirror advisory
session evidence and do not grant GitHub authority.
CodeRabbit verified and resolved all three findings: structured 503 handling,
audited service denials, and retry proof. It explicitly confirmed the latest
retry cases after
1c004f1f. Its general new-review check is rate-limited;that status is not treated as a fresh full review.
Test and CI integrity
Exclusive tests of removed activation/packet-write APIs are retired with explicit
replacement owners in the record. Required identity, grant, assignment, lineage,
rollback, privacy and retained submission/checker behavior remain covered.
No workflow, timeout, runner, dependency, exclusion or floor was weakened. The
replacement tests remain in the canonical lane inventory. The 78% global and
90% protected floors stay blocking.
Boundaries and human review focus
This does not activate guide upload, public ART-backed Submission creation,
REV/CON, or the remaining management/read authorization cutovers. Existing
Submission composite-ownership database hardening remains separately recorded;
this PR does not claim privileged direct-SQL lineage protection.
The roadmap is updated in this PR for intended merged TASK authority and retired
public surfaces, while keeping remaining creation/lineage work explicit.
PR #396 and this PR have sibling migrations after
0016_guide_document_runtime.Whichever merges second must reconcile its migration and shared fixtures with
main. The guide author has also been notified to adopt the coverage repair.
Human focus: exact project authority, preserved assignment/locked lineage,
retirement of the unsafe public writer, test replacement fidelity and hidden
API exposure. GitHub approval and merge remained human-owned; the human merged this PR after the checks passed. PR #396 remains open and must reconcile its sibling migration and shared fixtures against the new main before its own merge.
