Docs for #1165: in-progress marks only a live Run (grill, ADR 0029, glossary) - #1908

Summary

The docs side of the #1165 grill, which settles that in-progress marks only a live Run. Spec #1901 and its Tickets #1902–#1904 implement it. Docs only, no code.

What the glossary now says, against main:

 Claim
-  the mark that the factory has taken an issue; stays while its pull request
-  waits for review or its Run failed, until the Day shift relabels it
+  the mark that a Run is live; ready for review → no label,
+  failure with work on origin → agent-failed in its place,
+  Spec run only waiting → ready-for-agent back on the Spec
 Failure limit
-  comes off when the Day shift … takes `in-progress` off, leaving no `needs-triage`,
-  … by relabelling a failed triage issue
+  comes off when the Day shift … takes `agent-failed` off
+  counts failed Custom processes too (#1583)
 Sweep
+  also takes `in-progress` off open issues that carry `agent-failed`
 Recovery
+  posted as a generated issue comment on `agent-failed` issues, except Security fixes;
+  a waiting Spec gets a comment naming what each Ticket waits on

Merging main brought in #1695's Triage-run glossary terms (#1894). Those are kept, except its extra take-over signal ("relabelling a failed triage issue"), which the #1165 grill (Q2.1) replaced with the single rule above. This ADR is numbered 0029 because main already has its own 0027 and 0028.

Evidence

Execution evidence

• Before: scripts/affected-tests main, run from a stale local main without site dependencies installed: FAIL npm test --prefix site (0.17s) with ERR_MODULE_NOT_FOUND, a setup failure.
  After: scripts/affected-tests origin/main after npm ci in site/: PASS npm test --prefix site (30.53s). The selected cargo test --test share_card --test site_deploy can't build on macOS (thirdshift supports Linux only), so CI runs it.

Merge Danger

Door: two-way

Docs only. The glossary and ADR describe behaviour that #1902–#1904 haven't built yet, so until they land the glossary is ahead of the code on how a Claim ends.

Blast Radius: docs

A Spec run on #1901 reads the glossary and ADR from its Base branch, so merging this first gives it the settled vocabulary.
