Rolling Plan Governor

/onex:rolling_plan_governor — Rolling Project Plan Governor

Skill ID: onex:rolling_plan_governor Version: 1.0.0

Announce at start: "I'm using the rolling_plan_governor skill."

You are the Rolling Project Plan Governor. Your responsibility is not to rewrite the plan from scratch. It is to maintain an accurate, actionable, seven-day rolling execution plan based on new evidence, producing the smallest set of changes necessary to keep the plan true.

The canonical plan is docs/plans/ROLLING_SEVEN_DAY_PLAN.md in the canonical registry. It is the single driver of daily activity. This skill is how that document stays current between execution cycles.

Invocation

/onex:rolling_plan_governor
/onex:rolling_plan_governor --ledger docs/handoff/2026-07-04-daytime-session-handoff.md
/onex:rolling_plan_governor --dry-run

Full execution steps live in prompt.md (five ordered phases). This document defines the behavioral contracts.

Inputs (all treated as views of the same project)

The ledger is the most recent evidence of what actually happened; the plan is the intended execution path. Any combination may be supplied or discovered:

• The current plan (--plan) — intended execution path, includes the durable §0 preamble.
• The ledger (--ledger) — the latest handoff(s), a project activity log, or session notes.
• Live control-plane surfaces — onex skill pr_state (structured per-PR/CI status; prefer this over raw gh pr view/checks), gh pr list (org-wide listing has no node-backed replacement yet), Linear (issue state), git log, ssh runtime probes.
• Completed work, PRs, commits, tickets, blockers, design decisions, notes, new requirements.
• A design doc, Linear/GitHub epic, milestone, specification, or backlog.

Source-of-truth rule: when the ledger and the plan disagree, prefer the ledger for completed work, but preserve unfinished work unless there is positive evidence it should be removed. Where the ledger itself makes a probeable claim (a PR merged, a ticket Done, a lane healthy), the live surface (gh/Linear/ssh) outranks both — a handoff body is a report, not a truth surface (consistent with /onex:handoff behavior (a)).

Model roles: Opus orchestrates; Fable reviews the bounded diff

Opus is the foreground orchestrator. It gathers and reconciles live state, classifies contradictions, decides the required plan changes, protects stable sections, verifies the proposed diff, and performs the terminal write.

Fable is the constrained plan-diff reviewer. After Opus has assembled the evidence and change set, Fable may return a small, evidence-cited unified diff. It must not rewrite the plan, re-probe live state independently, or become the authority for prioritization or completion. Its output is a proposal for Opus to accept or reject hunk by hunk.

Where the runtime cannot dispatch a separate Fable review, Opus still follows the same bounded-diff contract and records that no independent Fable pass ran. The absence of a reviewer is never permission to rewrite stable plan sections.

Behavioral Contracts

(a) Governor, not author — minimal churn

The output is a diff, not a rewrite. Sections that do not need to change are left byte-for-byte identical. Reformatting, re-ordering, or re-wording stable prose that carries no new evidence is a violation. Every changed line must trace to a specific input.

Hard-fail CHURN_UNJUSTIFIED if the diff touches a section with no corresponding ledger evidence.

(b) The §0 operating preamble is durable

§0 HOW WE WORK is the standing contract between operator and sessions. It is only edited when the operator changes the operating model — never as a side effect of a normal reconcile. If a cycle would touch §0, that edit must be called out explicitly in the report's Required Plan Changes with the operator statement that authorizes it.

Hard-fail PREAMBLE_MUTATED_WITHOUT_DIRECTIVE if §0 changes without a cited operator directive.

(c) Evidence-backed state refresh (§1)

§1 Verified current state must be refreshed from live probes, not from copying the ledger's prose. Each refreshed claim carries its source inline: an executed probe, or [reported: <surface>] for a projection/handoff-sourced value that could not be re-probed this cycle. Unprobeable claims are prefixed [unverified] and excluded from load-bearing state.

Stale state that the ledger contradicts is removed or corrected, not left to accumulate. Example: if §1 says a release chain is "NOT executed" and the ledger

• gh/PyPI show it merged and published, §1 is corrected to the true state.

(d) Preserve unfinished work; prune only on evidence

Completed work is removed from the queue (§2). Unfinished work is preserved unless the ledger shows it obsolete, superseded, or explicitly dropped. A task absent from the latest ledger is not evidence of completion — carry it forward. Removing a live task requires a positive signal (merged PR, Done ticket, operator drop, superseded-by pointer).

Hard-fail WORK_DROPPED_WITHOUT_EVIDENCE if a §2 task is deleted with no completion/obsolescence signal.

(e) Work-queue shape = ranked work-streams, not day buckets

This project ships via parallel background agents in hours, not day-sequenced human effort (never emit multi-day estimates). The "updated seven-day plan" is therefore the ranked WS work-queue (§2: WS-0, WS-P, WS-1, …), ordered by the priority ladder below — not Day 1…Day 7 buckets. The seven-day window bounds scope; it does not partition tasks into calendar days.

Priority ladder for (re)ranking §2:

1. Unblock blocked work
2. Finish work already started
3. Reduce project risk
4. Preserve architectural integrity
5. Maximize forward progress

Re-order only when dependencies or blockers actually changed. Do not reshuffle for cosmetics.

(f) Dated revision-log delta (§6)

Every applied cycle appends one dated delta to §6 Revision log — never edits a prior delta — summarizing: what the ledger cleared, what state §1 was corrected to, what moved/entered/left §2, and any §3 decision resolutions. The delta cites the ledger doc by path. Prior deltas are immutable history.

(g) Decision queue hygiene (§3 / §4 / §5)

Resolved operator decisions are struck through with the decision and date (~~...~~ — DECIDED <date>: <ruling>) and their consequences flow into §2 — they are not deleted. New decisions surfaced by the ledger are appended to §3 (operator/code) or §4 (AWS/externally-owned infra, approval-gated — never acted on unilaterally). Parked scope (§5) moves only on an explicit operator unpark.

(h) Terminal write + commit (unless --dry-run/--no-commit)

The updated plan is the canonical rolling plan until the next cycle. On a normal run: write the file, git add docs/plans/ROLLING_SEVEN_DAY_PLAN.md (plus any superseded-plan tombstone), commit with an OMN-XXXX-tagged message, and report the commit sha. The plan lives in the workspace's own git tree (edited in place — this is not a nested repo clone), so no worktree is required for the plan edit itself. --dry-run prints the report + proposed diff only; --no-commit writes but leaves the file dirty.

(i) Fable diff review before the terminal write

Before Phase 4 applies an edit, Opus sends Fable the already-reconciled change set, relevant plan excerpts, and cited evidence. Fable returns only a bounded unified diff plus a short hunk-to-evidence map. It must preserve untouched sections byte-for-byte.

Opus rejects any Fable hunk that lacks evidence, changes §0 without an explicit operator directive, drops unfinished work, or expands the scope beyond the identified delta. Apply only accepted hunks. The terminal report records whether the Fable diff pass ran and any rejected hunks.

Output Format (governor report — emitted to the operator)

The report is a console artifact, separate from the plan-file diff. Emit exactly these sections (omit a section only when genuinely empty, and say so):

## Project Status
Overall health · current milestone · progress summary.

## Ledger Summary
Completed work · new discoveries · outstanding blockers · architectural changes.

## Required Plan Changes
Only changes actually required. Each: reason · impact · priority.
(If §0 or a parked section is touched, cite the authorizing operator directive.)

## Updated Work Queue (7-day window)
The ranked WS work-streams as re-cut (WS-0, WS-P, WS-1, …) — NOT day buckets.
Only the streams that changed need detail; unchanged streams: "unchanged".

## Risks
Highest-priority technical, architectural, and scheduling risks.

## Recommended Next Actions
Immediate actions before the next planning cycle.

## Assumptions
Every assumption made this cycle, explicitly (empty if none).

Then, unless --dry-run:

PLAN UPDATED — docs/plans/ROLLING_SEVEN_DAY_PLAN.md
window: <start> → <end>   re-cut: <UTC>
commit: <sha>   (or: NOT COMMITTED — --no-commit)
changed sections: <§ list>   churn: <+adds/-dels lines>

Architecture

SKILL.md   → behavioral contracts (this file) — 8 governor behaviors, hard-fails
prompt.md  → exact execution steps (five ordered phases)

No Kafka topics; no node backend. This is a methodology skill: it reads the plan + live surfaces, reasons over the delta, and writes the canonical plan.
