card #71: kept CHANGELOG.md (generated)

Objections go back to the worker, with the review attached (#59)

Revise loop for `/time retry`: an open PR's reviewer comments go to the worker on the same branch, open_pr updates the open PR, the card returns to `dispatched`, and verdicts older than the last revision no longer count. Check 55 covers it.

Reviewed: Approve by Time's reviewer (haiku); the two confirmation points answered by the steward. Merged by the CEO session on the owner's explicit clearance after eleven steward sign-offs were blocked by a session permission guard.

Closes #53

+"""Claude delegation: a bounded API task dispatched through a workflow, with a job receipt a caller can fetch.
+
+    python3 .github/time/delegate.py run              # in the `delegate` workflow (workflow_dispatch inputs arrive as env)
+    python3 .github/time/delegate.py fetch <id>       # read back and verify a receipt by its correlation ID
+    python3 .github/time/delegate.py id <caller> <key>  # the correlation ID a caller will get for (caller, key)
+
+Not a new provider client: the model call is time.py's `think`, so seat routing, the Anthropic client, retries, the
+ledger and the dollar governor (TIME_DAILY_USD / TIME_MONTHLY_USD) are the ones every other Time workflow uses. Nothing
+is posted to an issue: the transport is workflow_dispatch in, and a receipt out.
+
+Inputs (all env, set by the workflow from its dispatch inputs; never interpolated into a shell):
+  DELEGATE_TASK   the prompt, at most MAX_TASK characters
+  DELEGATE_SEAT   `sonnet` or `opus`
+  DELEGATE_KEY    idempotency key, 8-64 chars of [A-Za-z0-9._-]. NOT a secret: it appears in the run name.
+  GITHUB_ACTOR    the caller; must pass time.py's `trusted()` (owner, TIME_TRUSTED, collaborator)
+
+Correlation ID: `dlg-` + the first 20 hex of sha256(lowercase(caller) NUL key). The caller can compute it before
+dispatching, and two callers can never read or collide with each other's keys.
+
+Receipt: time/delegations/<id>.json on the default branch (durable, pushed like the spend ledger), and the same JSON on a
+`TIME-RECEIPT {...}` line of the run's log at every state change (the Actions run/log API). State machine:
+queued -> running -> succeeded | failed. A receipt holds the request's hash (never the task text), the source SHA and
+run URL, the model, tokens and dollars, the result and its sha256, or a redacted error. `fetch` recomputes the hash.
+
+Duplicates: the same (caller, key, request) after a success replays the stored receipt and spends nothing; while a run is
+live (updated within STALE_MIN minutes) it reports the live state; after a failure or a stale run it retries, up to
+MAX_ATTEMPTS. The same key with a different seat or task is refused. Failed attempts are retryable by re-dispatching.
+
+Secrets never reach a receipt or the log: the task is stored only as a hash, and every result and error passes through
+`redact` (env secret values, key-shaped strings, credentialed URLs, bearer tokens) before it is hashed or written.

 ## [Unreleased]
 
+### Added
+- Claude delegation over `workflow_dispatch` (`.github/time/delegate.py`, tests in `test_delegate.py`): a bounded task for the `sonnet` or `opus` seat with an idempotency key, run through time.py's own `think`, seat routing and dollar governor. Each job has a stable correlation ID (`dlg-<20 hex>`, from caller and key) and a receipt (`queued`/`running`/`succeeded`/`failed`, source SHA, run URL, model, tokens, dollars, result and its hash) at `time/delegations/<id>.json` and on `TIME-RECEIPT` log lines. Duplicate keys replay the stored result without spending, a failed key retries (3 attempts), and the task text, secrets and key-shaped strings never reach a receipt or log. No issue comments. The workflow itself is a proposal in `time/delegate/delegate.yml`: it needs a human to review and install it under `.github/workflows/`.
+
 ### Security
 - The worker's own commit status (`time/worker-run`) can fail or delay a merge but never earns one: with no other check on the PR head, Time dispatches the project's CI workflow on the PR branch (`TIME_CI_WORKFLOW`, default `ci.yml`, which must accept `workflow_dispatch`; GitHub skips `pull_request` runs for pushes made with the Actions token) and merges on that. `off` keeps the old "no checks" stop.
 - `.github/` is protected from auto-merge whatever `TIME_PROTECTED` says.
@@ -18,6 +21,7 @@
 - The second fix round escalates to Kimi's code model (`venice:kimi code`) instead of grok 4.7: still a different model from the first round, at a fraction of the cost. `TIME_VENTURE_ESCALATE` overrides it.
 
 ### Added
+- Objections go back to the worker. `/time retry` on a card whose PR is open hands the worker the reviewer's latest comments (marked as the reviewer's, strangers' left out) on the same branch; `open_pr` on an open PR updates its description instead of failing; the card goes back to `dispatched`, so the next beat reviews again and an objection older than the push no longer counts.
 - A batch's children start in the tick that spawned them (GitHub lists a card made a moment ago only later, so they used to wait a tick).
 - Build briefs keep claims to what the code does: no promised features or schedules, and the trending repos are the wave a venture rides, never something it "builds on". Fix rounds take a failing claim off the page rather than building a feature in a hurry. In the first live batch, every fix round was a claim the code didn't back.
 - Venture batches (multi-ceremony): one batch card scouts once, the seats pitch a field (rounds until there are 2k pitches), and the board ranks the whole field; the top k, each wanted by two seats, become venture cards in the batch's own milestone. They run the ordinary loop side by side and launch together: a child that passes its checks waits at `ready` until every sibling is settled or the hold (`TIME_VENTURE_BATCH_HOLD_HOURS`, 6) runs out; stragglers then launch alone. No child left behind: a held child gets one batch retry, and held again it is counted dead with its reason. A retro on the batch card compares the cohort's signups against each plan's lines, then the card and milestone close. Set `TIME_VENTURE_BATCH=3` to make batches the daily default, or Actions → venture → Run workflow → "batch".
