+The PR's linked Jira ticket is now staged deterministically as `ticket-context.json` (new lib/stage-ticket.ts, run from stage-pr.ts): when a consumer configures `REVIEW_JIRA_BASE_URL` (variable) plus `REVIEW_JIRA_EMAIL`/`REVIEW_JIRA_API_TOKEN` (secrets), the staging collects every issue key the PR references (title, head branch, description; known key-shaped noise like UTF-8 or SHA-256 sinks below plausible keys before the cap of 5 applies) and fetches each read-only on the host, before the agent starts; every degradation (unconfigured, no key, 404, fetch failure) stages `{available: false, reason}` and never fails the run. This replaces the completeness reviewer's in-prompt Jira/Confluence read grant, which was dead text: no consumer ever provided the token it promised and the firewall egress never included the Jira host, so its fallback clause fired on every run. The agent sandbox needs no Jira egress and never sees the credentials. The first-principles reviewer gets the staged ticket too (its whole mandate is the stated rationale, which it previously read only via the author's summary), plus two prompt rules minted from webapp#41609: a finding that pushes against a stated, rationale-backed decision must rebut the rationale with new evidence or not post (an observation your own prose concedes is not a finding), and several observations sharing one premise merge into one finding.

+/**
+ * Deterministic linked-ticket staging: fetch the Jira issues the PR
+ * references and write them to /tmp/gh-aw/review/ticket-context.json
+ * alongside the rest of the pre-agent staging (stage-pr.ts), so the
+ * sub-agents that reason about the PR's stated intent (completeness,
+ * first-principles) read the actual tickets instead of reconstructing intent
+ * from the author's summary of them.
+ *
+ * History: the completeness prompt used to GRANT itself a Jira/Confluence
+ * network read ("the tokens are scoped read-only and provided by the consumer
+ * repo"), but no consumer ever provided a token and the firewall egress list
+ * never included the Jira host, so the grant was dead text and the fallback
+ * clause ("fall back to the PR description alone") fired on every run. This
+ * module replaces that unplumbed in-agent fetch with the same pattern every
+ * other input already follows: fetched once, deterministically, before any
+ * model runs, with the agent sandbox needing no Jira egress at all.
+ *
+ * Candidate stance: every key-shaped token in the title, head branch, and
+ * description is a candidate (deduped, in order of appearance). Known
+ * key-shaped noise (UTF-8, SHA-256, CVE-2024-1234 all match the regex) sinks
+ * to the back of the candidate list before the MAX_TICKET_FETCHES cap
+ * applies, so the cap spends its budget on plausible keys first; whatever
+ * survives the cap is tried, and misses simply 404 and drop silently. The
+ * residual bound: a real key is only ever crowded out by MAX_TICKET_FETCHES
+ * or more earlier key-shaped tokens that are not on the noise list.
+ *
+ * Failure stance: a ticket is context, not a prerequisite; a review must run
+ * identically on a PR with no ticket, a repo with no Jira credentials, or a
+ * Jira outage. So this staging NEVER fails the run: every degradation writes
+ * `{available: false, reason}` and the prompts fall back to the PR
+ * description, exactly as they did before this existed. The file is always
+ * written, so readers never need an existence check.
+ *
+ * Trust stance: ticket text is untrusted input under review, same as the PR
+ * description. The staged JSON carries content verbatim (size-capped); the
+ * consuming prompts carry the never-follow-instructions rule. The disclosure
+ * bound (which tickets author-written keys can pull into a review that posts
+ * publicly) is the service account's Jira permissions, enforced server-side:
+ * grant it Browse Projects on only the projects reviews may quote, and
+ * anything else 404s like a stale key.
+ *
+ * Determinism boundary: authenticated GETs plus pure functions of their
+ * results; no model call, no prose about the code under review.
