feat(backlog): add the metrics synthesis step to org-roam

"synthesize backlog metrics" reads the JSONL union across personal projects and computes the per-run rollups, the trends, and the corrections signal (a later revert or fix touching an autonomous commit's files within ~14 days, a flag for review rather than a conviction). It writes one :agent:metrics: KB node linking back to prior synthesis nodes. Work and unknown projects are excluded by the denylist classification and reported per the refusal contract.

The step is read-only over the logs plus the single KB write. It never mutates the JSONL, todo.org, or any project tree.

 - =work-the-backlog.org= — the autonomous task-execution loop, the single home for working a batch of marked tasks unattended: takes an ordered task set (explicit list or tag query) + session mode (=file-only= default / =autonomous-commit= + paging) + a hard run cap; each candidate passes the mechanical eligibility gate (status =TODO= + =:solo:= per the project's scheme header) and the four-item defer checklist, then is implemented to the full quality bar (TDD, =/review-code=, =/voice=) as its own logical commits. Fed by the inbox auto-loop's chain step (yes-gated, file-only, cap 1) and the no-approvals speedrun preset (pre-flight Q&A → autonomous-commit + always-push + end-of-set page over an explicit ordered list).
   - Speedrun triggers: "speedrun", "no approvals speedrun", "speedrun these: <task set>" — any phrase containing "speedrun" routes here (the preset), never to =no-approvals.org=
   - Manual triggers: "work the backlog", "work the backlog with <task set>" (file-only defaults)
+  - Synthesis trigger: "synthesize backlog metrics" — read the per-project metrics logs, compute trends + the corrections signal, write one =:agent:metrics:= KB node (personal projects only)

 The batch-ask (step 4-5) is one message: each question names its task, puts the recommended answer at item 1 when there is one (per =interaction.md= — inline numbered, no popup), and offers "skip this" as the last option. Before the run starts, write each answer into its task's body in =todo.org= as a dated line — the implementation works from the recorded decision, and the record survives the session. The Q&A fires only under this preset; the loop caller never asks (its decision-needing tasks defer).
 
+* Synthesis: metrics → org-roam KB
+
+Trigger: "synthesize backlog metrics" (optionally a weekly scheduled run). This is the read side of the metrics log — Craig's ask was "gather data and create org-roam articles we can look at later," and this step is the second half. It is read-only over the logs plus exactly one KB write.
+
+1. *Gather the JSONL union.* Discover =.ai/metrics/work-the-backlog.jsonl= across the project roots (dirs carrying =.ai/protocols.org= under =~/code=, =~/projects=, =~/.emacs.d=). Classify each project per =knowledge-base.md= (work-root denylist, never inference) before reading it into the union.
+2. *Enforce personal-only.* A work-classified or unknown project's metrics never enter the KB write — they stay in that project's own log. Report the exclusion per the KB refusal contract: the classification, a one-line redacted summary, and where the data stayed.
+3. *Compute the rollups and trends.* Per run: attempted / completed / deferred (by reason) / dropped / failed, wall-clock total, commits landed, review findings per commit. Trends across runs: completion rate over time, defer-reason distribution, findings-per-commit trend.
+4. *Compute the corrections signal* — the key metric. For each =commit_sha= in the window, check that project's history for a later commit (within ~14 days) that reverts it or carries a fix touching the same files. A clean run is one whose autonomous commits survive untouched; a flagged run is what Craig reviews by hand. This is a cheap proxy, not proof — it flags candidates, it doesn't convict.
+5. *Write one KB node* at =~/org/roam/agents/YYYYMMDDHHMMSS-backlog-metrics-<window>.org= per =knowledge-base.md=: =:agent:metrics:= filetags, a concise title, the rollup table, the trend narrative, and =[[id:...]]= links to prior synthesis nodes so the series is traceable. Pull before writing, commit and push after — the normal KB session discipline.
+
+The KB node is the artifact Craig reads later: "are the runs completing more and getting corrected less?" should read off the trend table without touching raw logs. Synthesis never mutates the JSONL, todo.org, or any project tree.

-Created 2026-07-02 as Phase 1 of the autonomous-batch execution spec, reconciling the inbox-zero "Phase E" proposal and the =.emacs.d= speedrun proposal into one execution loop. The auto-inbox-zero execute step in =inbox.org= reverted to routing-only in the same change so this file is the loop's only home. Phase 2 (same day) wired both callers: the auto-loop chain step and the speedrun preset's trigger phrases.
