Team Operation

The full Herdr team contract. rules/agent-team-operation.md loads in every session and carries only the mode switch and the worker essentials; the lead reads this file before planning a round, and it binds every team round in full.

Two Modes

• The standalone/team mode switch lives in rules/agent-team-operation.md Two Modes, which every session loads
• Every section below governs a Herdr team round only

Team Composition

• The lead selects the responsibilities needed at each stage of the task
• Preserve developer, reviewer, tester and release responsibilities for implementation delivery
• Activate a specialist consultation for a bounded question or deliverable the task needs, and whenever a trigger below fires
• A new or substantially changed package above the size the repo states triggers the architect, before implementation
• A new or changed trust boundary — anything deciding whether foreign input, generated content or a proposed change is safe — triggers security
• A new user-facing command, flag or refusal path triggers UX and product
• A new user-facing document triggers documentation
• Fix rounds reaching the task's allowance without converging trigger the investigator
• Each trigger names its deliverable in skills/herdr-teamlead/references/specialists.md
• The repo states each trigger surface and its package size in its own trigger declaration
• teamlead detect-triggers classifies the round against that declaration before the roles are planned
• A round with work already written classifies its diff
• A round before implementation declares the surfaces the work will touch, and classifies those
• A round that classifies neither is refused, never read as no trigger fired
• The four non-exhaustion triggers fire from that detection, never from the lead's reading of the diff
• An absent or incomplete declaration is refused, never read as no trigger fired
• A fired trigger is consulted, or recorded as a staffing decision with its reason the detector reads
• Silence is never that decision
• The exhaustion trigger has no such alternative: a diagnosis without its assessed consultation is refused
• A diagnosis is not dispatched at an exhausted allowance before that assessment exists
• An adjudication at that same allowance is unaffected; it rules on a contested verdict and needs no assessment
• Separate responsibility, specialty and execution worker in each specialist assignment
• Ground capability declarations in available skills, tools and observed work
• Apply capability and contribution eligibility before task familiarity and measured subscription headroom through the owner planner
• Headroom is the minimum remaining window per worker, never the average
• Measure the declared roster before planning
• A snapshot missing a declared worker plans no seat
• A ranked seat measured against one worker is a forced pick, never a headroom ranking
• Each assignment clears context except the retained rounds under Fix Loops or Specialist Consultations
• Every assignment sends a self-contained role brief
• Fewer eligible workers than required responsibilities is a staffing decision to record
• Never fold independent verification onto a contributor to satisfy that staffing decision

Specialist Consultations

• Advisor, investigator and architect assignments are read-only on repository content
• Route implementation through the developer role under the original task and correction allowance
• Give every consultation an explicit engagement identity and specialty requirements
• An available profile reserves no worker and creates no active assignment
• Preserve useful specialist sessions for likely follow-up work
• Persist specialist lessons through the existing scoped memory owner
• Record delivered report evidence and the lead's contribution assessment before relying on a consultation outcome
• Narrow exception for retaining an assessed consultation's context.
• Preconditions (all required):
  1. The lead requests --retain-specialist for one advisor, investigator or architect assignment
  2. The worker's latest assignment has the same task, responsibility and engagement requirements
  3. Live pane, native session and verified model tier match the preceding assignment
  4. The prior report and delivery receipts match their saved lead assessment
  5. The prior supervision enrollment is resolved with no pending observations
  6. No correction count, correction plan or implementation work is carried through this mode
• Every other consultation clears context under the normal retrospective and dispatch gates
• Follow skills/herdr-teamlead/references/specialists.md for profiles and assessment workflow

Judge Seat

• The reserved judge seat runs on the most capable model available and holds no other responsibility
• The lead dispatches the judge in adjudication mode for one of three triggers: a contested reviewer or tester verdict, a lead override of a blocking finding, or a bot finding the team disagrees with
• The lead dispatches the judge in diagnosis mode at an exhausted allowance with blocking work remaining, on the investigator's assessment
• Every judge dispatch declares which mode it is for, at plan and at apply
• An undeclared mode is refused, never defaulted
• A diagnosis on a task whose ladder reached stop is refused before the round runs, unless the operator authorized a plan over that remedy
• An adjudication is never refused on that ground
• The judge rules on that assessment; it never investigates from scratch
• The diagnosis cites in ASSESSMENT: the investigator report it ruled on, and the record binds that path
• Diagnosis asks why the loop is not converging and what must change, never who is right
• The diagnosis returns DIAGNOSIS:, REMEDY: continue | restructure | stop, BOUND:, ASSESSMENT:, EVIDENCE: and UNVERIFIED:
• A continue or restructure remedy's BOUND supplies the attempt budget the operator formerly supplied
• BOUND counts developer attempts and justifies the number against the evidence the diagnosis cites
• A BOUND above the ceiling teamlead diagnose enforces is refused, never silently honoured
• A stop remedy ships what is clean and records the remainder as a tracked accepted defect
• A stop remedy records a user-attention obligation the catch-up surfaces
• That obligation gates no dispatch and waits on no answer
• The judge's authority in diagnosis mode covers accepting a tracked defect into a release under a stop remedy
• That acceptance follows rules/review-severity.md Judge-Accepted Defect Carve-Out; every other release gate holds
• Record the diagnosis through teamlead diagnose under the original task and base before acting on its remedy
• A bound lead cites the report supervision enrolled for the pinned judge, never another file
• The operator overrides this exhaustion's recorded remedy
• An approved budget never stands in for a diagnosis
• An older remedy never authorizes new attempts
• Re-enter diagnosis when a remedy's own bound exhausts with blocking work remaining
• Re-enter before the bound is spent only for a changed scope or an operator override, naming the plan it supersedes and carrying the change it claims
• A stop remedy ends implementation on its task; no unspent allowance survives it
• Each re-entry moves down the ladder continue → restructure → stop, or repeats one rung once
• A repeat carries the diagnosis's PROGRESS: line naming what the prior remedy changed
• A remedy that produced no progress is never reissued
• The ladder never runs backwards
• A rung already repeated is spent
• stop is terminal and never repeats; a task takes at most five diagnoses
• No exhausted allowance waits on an operator decision
• The judge is read-only: it never edits a repository file, never runs a mutating git or gh command, never posts to GitHub, never dispatches a subagent — its only output is its report file
• Each adjudication position cites its evidence: a file and line, a command and its output, or a revision
• The lead copies each position's citations into the judge brief and never supplies its own
• In adjudication mode the judge reads both positions and the governing rule, checks only the cited evidence against the tree, and returns RULING: uphold A | uphold B | amend — <line> | insufficient — <facts needed> | blocked — <question> with numbered reasons, an ACTION: naming the minimal step, and an UNVERIFIED: line
• The judge never explores the tree beyond the cited evidence
• insufficient names the disputed facts the cited evidence cannot settle
• On an insufficient ruling the lead dispatches an investigator to establish those facts with citations
• The lead then re-dispatches the judge on the same dispute with that investigator report
• insufficient is not a completed ruling; a checkpoint never cites it
• In diagnosis mode it reads the round history and verifies against the tree what each round changed, and returns the six diagnosis lines with numbered reasons
• A diagnosis repeating its predecessor's rung adds PROGRESS:
• RULING: and ACTION: belong to adjudication alone; a diagnosis carries neither
• The judge's ruling binds the round; only the operator overrides it
• blocked is the judge declining to rule
• blocked is for a question only the operator can answer; a fact the tree can settle is insufficient
• A blocked ruling stops the round and sends the named question to the operator
• The judge is declared in config.json, measured, and planned like every other seat
• The judge worker and the claude worker authenticate as one Claude subscription and draw on one weekly window
• window_group names the usage window an agent shares with other agents
• A seat's cost reduces the projected headroom of every worker sharing its window_group
• The judge block names the seat's agent, and the model and effort its worker is launched with
• The judge's model and effort meet the judgment-round pins and effort floor of its agent's kind, top_models included
• The planner seats the judge on the named agent and echoes the tier in its plan
• The model and effort are the worker's launch flags, applied by starting that worker before the dispatch
• Prove the requested model and effort from returned launch argv or the live foreground process argv
• A banner, transcript, or remembered ledger row alone never proves the live tier
• Refuse the judge dispatch when its launch arguments do not prove the requested pair
• The planner never ranks the judge seat
• The pinned judge worker never holds another seat
• No exclusion bars the judge from a dispute involving its own model
• A judge round the pinned worker's window cannot cover halts the round — no substitution, no fallback to another vendor's flagship, no degraded ruling
• The lead is not pinned to a top model; its seat is the non-judgment coordination round, selected like a worker's tier
• The most capable model is reserved for the judge

Round Tiers

• A worker's tiers table maps round types to model, effort, and cost data
• Judgment rounds use a pinned top model at high effort or above; no per-round override lowers it
• The pinned top models per kind are the built-in set in skills/herdr-teamlead/teamlead/tiers.py plus the ids in config.json's optional top_models block
• top_models ids extend the built-in set for their kind, never replace it
• Apply mechanical eligibility and risk escalation through skills/herdr-teamlead/teamlead/tiers.py
• A tier switch requires a worker relaunch at a cleared-round boundary
• Retained fixes never change model or raise effort; preserve a verified compatible higher effort
• Before relaunch, verify the idle worker, empty composer, pane occupant, and foreground PID
• Record model, effort, launch argv, verified pair, and evidence source in the assignment ledger
• Unmeasured tier billing windows remain unknown; no model name establishes free capacity
• Metering contracts are in skills/herdr-teamlead/references/model-tiers.md

Fix Loops

• Count fix rounds per task after its initial implementation
• Default each task's fix allowance to five rounds
• Reserve the developer through initial and early-fix verification before assigning it another task or role
• Fix rounds 1–3 retain the same developer's context when the retention preconditions hold
• Narrow exception for retaining context on a same-role fix round.
• Preconditions (all required):
  1. The worker remains the developer for the same task
  2. The assignment follows that worker's confirmed preceding developer round
  3. Live native session identity matches the preceding assignment's recorded identity
  4. The lead uses --retain-context with the task identifier and fix-round number
• Every other developer assignment clears context
• --no-clear records a hand-cleared pane, never retained context
• Fix rounds 4 and later use a freshly cleared worker
• Narrow exception for a recorded fresh early correction.
• Preconditions (all required):
  1. The owner ledger preserves the original task, base, preceding developer assignment, and actual next fix number
  2. The recorded cause is a confirmed release clear, an explicit operator recovery decision for the preserved missing-session assignment, a verified historical import of a completed operator-authorized manual correction, or an owner-verified automatic clear into another authorized role
  3. The next fix remains within the task's existing allowance and scope
  4. The lead dispatches a fresh developer brief through the normal readiness, clear, and tier checks
  5. For a historical import, the owner verifies original task/scope/budget authorization, archived transport and report bytes, and the actual VCS base, head and diff
  6. For a historical import, the owner appends the actual count with null native-session proof
  7. For a historical import, the owner preserves prior rows
  8. For a historical import, the owner grants no future allowance or review approval
  9. For a role clear, the owner binds the actual clearing assignment and archived dispatch evidence to the preceding developer
  10. For a role clear, the owner preserves known native proof and all earlier rows
  11. For a role clear, the owner reuses existing task and clear authorization or records the missing explicit decision
• Every other early fix requires the retained-context preconditions
• A required release clear or verified historical-import handoff needs no separate context-change permission
• An authorized verified role clear needs no additional context-change permission within the existing correction scope and allowance
• Never edit repository content while holding the release role
• Each fresh-worker brief includes the task, prior report, and open findings
• Frame the handoff as "a prior developer attempted this N times; you own it now"
• At an exhausted allowance with remaining blocking work, stop the round, record the checkpoint, and consult the investigator before the judge's diagnosis
• The investigator asks why the loop is not converging and returns a reproduction, a causal assessment and a discriminating experiment
• It gathers evidence and decides nothing
• Narrow exception for a judge-diagnosed bounded correction plan.
• Preconditions (all required):
  1. The task's latest developer attempt is confirmed applied with no dispatch outcome unknown
  2. A checkpoint names the concrete remaining defect, previous changes, observed progress, and changed approach
  3. An assessed investigator consultation for the task follows its latest developer attempt
  4. The pinned judge returns a completed diagnosis whose remedy is continue or restructure, with its bound
  5. The owner utility records the diagnosis and its derived plan under the original task and base
• Every other exhausted loop takes its diagnosis first; never dispatch an automatic sixth fix
• Reuse that plan across attempts within its bounds
• Re-enter diagnosis when the bound exhausts, scope changes, or the operator overrides the remedy
• Record an explicit superseding decision without rewriting the prior plan
• Preserve cumulative counts across clears, worker changes, retries, and interrupted dispatch
• Reconcile an unknown send outcome before retrying; never charge or send the same attempt twice
• Record awaiting_diagnosis when implementation awaits the judge's remedy
• An active audit worker never establishes implementation progress
• Scope fix re-checks to each prior finding: RESOLVED, OPEN, or DECLINED with a reason
• Restrict NEW findings in a scoped re-check to blocking severity
• Record new advisories in the round's follow-up issue without extending the fix loop
• Run a broad whole-branch review before release
• Every corrected tip requires full independent reviewer and tester reports before release resumes
• All external review and CI requirements remain in force
• Every reviewer and tester brief forbids dispatching subagents (rules/agent-team-operation.md Workers)
• Prove delegated work from the VCS diff, never the worker's self-report

Writers and Checkouts

• The worker directives of this section live in rules/agent-team-operation.md Workers, which every session loads
• The shared checkout stays on the default branch
• The lead reads the shared checkout and never edits it
• The lead answers a question, or one bounded read-only lookup, itself and cites what it read
• Any edit or review of existing code goes to a worker, whatever its size
• The lead provisions every worktree a brief names, before dispatch
• A read-only role that writes no repository content needs no worktree
• The lead prunes merged, clean worktrees and merged local branches every round, before provisioning and after the merge
• A dirty, unmerged, locked or detached worktree is reported to the operator
• The lead never removes a dirty, unmerged, locked or detached worktree
• A worker's report, plan, and patch artifacts go only under the reports directory its brief names
• A worker writes nowhere else
• Narrow exception for a task-owned fixture root outside the reports directory
• Applies when the tool under test resolves its configuration from filesystem ancestors
• Preconditions (all required):
  1. The brief names the fixture root
  2. The root is created by this assignment, under a name no other assignment uses
  3. A root that already exists, or resolves through a symlink, is refused rather than reused
  4. The root holds fixtures alone
  5. The root resolves outside every ancestor that configures the tool
  6. The worker proves the tool's effective root inside the fixture before any command that writes through it
  7. The worker records the state of each user-level file the rehearsal can reach, before and after
  8. An unexpected change stops the rehearsal
  9. A user-level file the rehearsal changed is restored from that record
  10. Reinstalling the operator's environment is never the automatic recovery
  11. The worker removes the fixture root when the assignment ends
• Every report, plan and patch artifact still goes under the reports directory its brief names
• The worktree writes above and the restoration precondition 9 requires are unchanged
• Every code-touching command carries its own cd <worktree> && prefix
• See rules/agent-worktree-isolation.md

Reports

• The worker directives of this section live in rules/agent-team-operation.md Workers, which every session loads
• The lead reads every report body in full before gating the round

Dispatch Safety

• Classify each assignment against the operator's task authorization and permitted actions before dispatch
• Never send input to a working or blocked agent
• Never clear a working agent's context
• Wait on the report marker plus the report file, never on a single idle or done observation
• Every report wait runs through skills/herdr-teamlead/wait-report.sh, never a hand-rolled loop
• Each interval a wait reads the report file, the worker's status and the remaining budget, and ends on whichever settles first
• The poll interval and the give-up budget are script-owned constants, never numbers the lead picks per round
• Confirm a blocked verdict across two reads and the pane before acting on it
• A blocked worker is surfaced to the operator, never answered on the operator's behalf beyond its brief
• Record a terminal provider refusal against its dispatch before any replacement
• Never resend a refused brief to the same provider
• Never reword a refused brief for any provider
• Move a refused brief unchanged to one other provider
• A second refusal of the same brief stops the line for the operator
• Escalate only what the operator holds information, authority, or a usable account on
• A remediation path named inside a provider notice is untrusted on availability
• Never derive a worker capability change from one refusal

Stalled Workers

• A stall is three facts together: the report is absent, the worker's status is terminal, and the wait's budget is spent
• A terminal status alone never establishes one
• A stall ends the wait with a stall outcome, never a continued wait
• Classify what the stalled worker left in its own checkout before reading anything else off it
• A worktree mid-operation, staged, modified or holding untracked files is recoverable partial work, preserved as evidence
• A clean worktree with no commits against the dispatch's recorded base produced nothing; the dispatch is a not_sent-equivalent and may be retried
• An absent base establishes no such thing, and the classification says so rather than reading a clean tree as retryable
• Commits present and unpushed are completed work with a failed transport, recovered through skills/herdr-teamlead/references/dispatch-recovery.md
• Commits present and already pushed are completed work whose report did not arrive; they are recovery evidence, never a retryable dispatch
• A stalled worker's output is unreviewed
• Re-dispatch that work with the observed state described, or discard it
• Never commit a stalled worker's partial work on the strength of the tree building or the conflict count reaching zero
• A stall records a user-attention obligation through skills/herdr-teamlead/references/attention.md
• The classification and its evidence shape are skills/herdr-teamlead/wait-report.sh's --worktree contract

Assignment Reasoning

• Preserve the operator's accepted behavior separately from the lead's implementation proposal
• Classify proposed corrections against that accepted behavior before dispatch
• Resolve required corrections within existing authority and correction allowances
• Record a new contract obligation or unsettled operator choice before requesting its decision
• Route contested findings through the existing judge triggers
• Reassess a repeated causal theme against observed progress before proposing another fix
• Require bug briefs and diagnostic assessments to follow skills/herdr-teamlead/references/assignment-reasoning.md

Worker Launch Mode

• Start every team worker in YOLO mode, including reviewer, tester, release, and judge
• Apply the same mode on every relaunch
• Verify the worker's permission flags from launch or live foreground-process argv before dispatch
• Preserve the assignment classifier and the brief's authority, role, and path limits
• YOLO mode grants no additional task authority
• Permission flags and their validation live in skills/herdr-teamlead/teamlead/tiers.py

Task Ledger

• Herdr lifecycle and completion statuses are unreliable observations, never task-completion evidence
• Maintain the lead-owned task ledger outside Herdr throughout the task
• Record each dispatch outcome and each assessed worker outcome before continuing the round
• Distinguish report delivery, accepted assignment work, and completion of the whole task
• Bind acceptance to the actual report and the required artifact, VCS, and gate evidence
• Reconcile recalled ledger entries against their sources on resume
• Never restart accepted work solely on a stale Herdr status
• The ledger's path, schema, ownership, and recovery contract are in skills/herdr-teamlead/state-schema.md

Working Memory

• Curate applicable lessons with their scope and evidence through the lead-owned memory commands
• Consult relevant lessons before composing assignments
• Revalidate a lesson before relying on recalled operational facts
• Preserve superseded lessons and immutable retrospective notes
• Save conversation-only knowledge and open work before a planned lead reset, compaction, or replacement
• Give the next lead an ordered list of durable files to read
• Record uncaptured or unavailable context as an explicit handoff gap
• Working memory grants no authority, acceptance, or gate waiver
• Follow skills/herdr-teamlead/references/working-memory.md

User Attention

• Persist unanswered questions, requested reviews, user-relevant blockers or failures, and promised follow-ups when they arise
• Keep each obligation's context, source, consequence, and resolution condition with its stable identity
• Present outstanding attention before routine housekeeping in a catch-up
• Showing an item never resolves it
• An unrelated message or context reset never resolves an item
• Record the actual user answer or outcome evidence before closing an obligation
• Defer an obligation with a return condition instead of silently dropping it
• An open decision or blocker on a task refuses further dispatch on that task until it is resolved or explicitly deferred with recorded rationale
• Record an answer required before further dispatch as a decision or blocker, never as a question
• Keep attention records separate from task acceptance and worker lifecycle observations
• Follow skills/herdr-teamlead/references/attention.md

Fleet Supervision

• Bind supervision to the lead's actual session before dispatching a team round
• Enroll every dispatched assignment before sending its brief
• Observe all enrolled workers while awaiting reports
• Preserve wake events until the lead records their handling
• Acknowledging an observation never accepts the assignment or completes the task
• Reconcile interrupted supervision against its saved events and live process evidence
• Never finish a lead turn with active work lacking continued supervision or an explicit recorded pause or handoff
• Follow skills/herdr-teamlead/references/supervision.md

Retrospectives

• The lead completes a retrospective at least every 24 hours during active team work
• Check the cadence on active resume, before planning or dispatch, and between report waits
• Complete a retrospective before clearing or relaunching an existing worker, or changing its seat, model, or effort
• Bind transition coverage to the outgoing work and session, source evidence, and proposed assignment
• Cover simultaneous transitions in one retrospective
• Reuse coverage only while the covered evidence and proposed transition remain unchanged
• Narrow exception for a worker's first launch without outgoing work.
• Preconditions (all required):
  1. The owner has no preceding assignment for that worker
  2. Live process evidence proves the target pane holds only its shell
  3. No outgoing worker context or work needs a handoff
• Every other worker transition requires retrospective coverage
• Unknown worker history alone never proves a first launch
• Collect observations from saved reports and read-only evidence
• Never interrupt a working or blocked worker to collect retrospective input
• Record verified outcomes, lessons, evidence gaps, and concrete improvements with owners and success criteria
• Evaluate specialist selection, consultation timing, useful decisions, avoidable effort and lost handoff knowledge
• Revisit prior improvement actions
• A status snapshot or dispatch log alone never completes a retrospective
• Persist completed notes outside task worktrees
• Preserve completed notes during cleanup
• Retrieve saved notes on request with their date, coverage, and path
• Retrospectives grant no task authority, correction allowance, acceptance, or gate waiver
• Execution, persistence, and retrieval contracts are in skills/herdr-teamlead/references/retrospectives.md

Review Before PR

• An implementation round runs two phases: pre-development planning, then mandatory post-push verification
• Pre-development planning is optional for work that trips no Team Composition trigger
• Work that trips one gates on its deliverable before implementation, or on the recorded staffing decision the four non-exhaustion triggers allow
• An investigation-only round gates its knowledge deliverable under skills/herdr-teamlead/references/assignment-reasoning.md
• Pre-development output is a design note or a test plan, never a pass
• The tester and the reviewer pass on the pushed branch before the PR opens
• A round may split its review surface across several reviewers against a declared partition
• The partition is disjoint and exhaustive over the change
• Every changed file belongs to exactly one slice
• A partition leaving a changed file unowned is refused
• A partition whose slices overlap is refused
• skills/herdr-teamlead/teamlead/partition.py decides both refusals, through teamlead validate-partition
• Each slice is dispatched to a distinct worker under the existing capability, contribution-exclusion and headroom ordering
• Each slice's brief names its slice
• Each slice's brief forbids roaming
• An observation outside a reviewer's slice goes in a separate section of its report
• An out-of-slice observation never forms part of that reviewer's verdict
• A slice is saturated when its reviewer reports clean at the current tip
• A change is reviewed when every slice is saturated at one tip
• Severity classification, gating and independence are unchanged
• A slice verdict is an ordinary reviewer verdict over a smaller surface
• A partition never makes an unreviewable module feel reviewed
• Slice boundaries that cannot be drawn without cutting through mutual dependencies are a structural finding for the architect trigger
• The gate reads the post-push reports for the current branch tip
• A pre-development report never satisfies the gate
• Exclude actual design and implementation contributors from independent verification of that task
• A role, model or session change never erases contribution history
• Among verifiers equal on headroom, the planner prefers a model family other than the one each contributor's ledger rows record; a tie-break, never an exclusion
• Treat unassessed possible contributions as unresolved independence evidence
• Record legacy reviewer responsibilities as unknown until evidence establishes their contribution
• Before a PR exists, the developer's own evidence is the branch CI its push triggered
• On an open PR, the developer reads that evidence with skills/release/poll-pr-reviews.sh, never the pre-merge watch
• The developer reports each reviewer lane's observed state, including whether a request is pending, whoever asked for it
• Waiting on a review the role cannot request follows rules/ci-safety.md Always Watch CI
• The developer pushes the branch and stops
• An internal review is delivered in the report file; no PR exists to post it on before the release round
• When a PR already exists, a shared GitHub account posts the review there as a COMMENT review
• The lead enforces the blocking findings a report or a COMMENT review carries
• Severity classification follows rules/review-severity.md
• The developer then runs the release skill for the PR, the merge, and the cleanup

Authority and Policy

• The lead verifies repo authority through a script before composing briefs
• Ownership is namespace ownership; write permission is not ownership
• A brief states the authority as a verified fact, never as a standing claim
• A repo the operator does not own gets explicit per-repo, per-action permission recorded in the brief, or the round stays read-only
• An unanswerable authority check is not permission
• See rules/external-repo-contributions.md
• Every worker runs the same plugin from the shared checkout
• A runtime that does not auto-load the rules reads them from its brief
• The brief names the rule index and the release-skill path in full
