Frank 99b9a6a17c docs(pi): unify split package trees; move live OMP pages to core

Two directories documented one concept (pi npm packages): top-level
packages/ (browser-use, permission-system) and pi/packages/ (peon,
web-access, subagents). Merged into pi/packages/ — one row per package
in a single index, detail pages kept as archive records. The root
index's 'OMP packages and skills' section was doubly wrong (packages/
was pi, not OMP); it becomes a Skills tooling section pointing at the
consolidated /skills/ tree.

Moved the two LIVE omp pages out of the retired-harness banner:
pi/statusline.md -> core/statusline.md, pi/subagent-limits.md ->
core/subagent-limits.md (both document omp behavior against
agent/config.yml + the installed bundle; pi/index.md itself admitted
the mis-shelf). Retargeted every inbound link (core/index, system/
dankserver, log x2, pi/index, settings x2, moved files' own xrefs).

OMP Subagent Limits & Fan-out Policy

Enforced caps on subagents spawned through the task tool / eval agent()+workpool() from this workstation (config root agent/config.yml, machine-live tier — the live-sync heartbeat commits it). Set 2026-10-19; values verified against the live config and the enforcement code in the installed bundle (@oh-my-pi/pi-coding-agent/dist/cli.js).

The caps in force

Key	Value	Default	Effect
`task.maxConcurrency`	2	32	Session-scoped semaphore; excess spawns queue, never drop.
`task.maxRecursionDepth`	1	2	Subagents cannot spawn their own subagents. See depth semantics.
`task.maxRuntimeMs`	1800000	0 (off)	Hard 30-min wall clock per subagent; overrun = `aborted`.
`task.softRequestBudget`	120	200	Wrap-up notice at 120 assistant requests; force-stopped to yield at 180 (1.5×).
`task.agentIdleTtlMs`	420000	same	Finished subagents parked to disk after 7 min idle (revivable via `agent://`).
`task.enableEffort`	false	false	Per-spawn `effort` hint hidden from the schema.
`task.isolation.enabled`	true	false	`isolated: true` spawns run in a copy of the checkout; only successful patches land (merge=patch, apply). Opt-in per spawn.
`task.completionProbe`	false	true	No periodic completeness side-requests into running subagents.
`tools.maxTimeout`	600	0 (off)	No agent may request a tool timeout above 10 min; kills `timeout: 0` runaways.
`providers.maxInFlightRequests`	see below	{} (unlimited)	Per-provider ceiling on concurrent LLM requests, shared across local omp processes.

Depth semantics — never set `maxRecursionDepth: 0`

Bundle predicate (U_): a session at taskDepth s keeps the task tool iff n < 0 || s < n where n = maxRecursionDepth. The preflight repeats the check (Cannot spawn another agent at task depth s; maximum depth is n).

n = 1 → main (depth 0) spawns; children (depth 1) have task stripped. This is "no nested subagents".
n = 0 → 0 < 0 fails → not even the main session can spawn anything. Don't.
n < 0 → cap disabled.

Per-endpoint in-flight ceilings

providers:
  maxInFlightRequests:
    "llamacpp (dankserver)": 3      # main session + up to 2 task/reviewer subagents
    "llamacpp (dankclaw)": 2        # frank-dragoon: security-reviewer + fallbacks
    "llamacpp (dankclaw-3090)": 3   # frank-zealot: scout/sonic/librarian/designer + smol/tiny/plan/commit/vision roles

Keys are provider ids = the quoted block labels in agent/models.yml (one provider per host:port). The consumer does a flat map lookup by provider id; absent or ≤0 = unlimited, otherwise clamped to ≥1.
Scope is per machine, per config root: it bounds what this workstation's omp processes put on each endpoint. Other workstations, OpenWebUI, and any non-omp client are not counted. Requests past the ceiling queue, never fail.
web/searxng intentionally uncapped.

Isolation note

task.isolation.enabled: true makes the per-spawn isolated flag available — it is opt-in per spawn, not a blanket sandbox. Requires a git repo; unavailable in plan mode; baseline snapshot capped at 1 GiB; backends resolve via isolation.backend: auto (overlayfs/reflink/rcopy chain on this box). Given the checkout is the deployment, prefer isolated: true for any subagent that edits tracked files.

Deliberately not set

bash.gitGuard — offered 2026-10-19, declined; destructive-git protection stays opt-in.
task.disabledAgents — no bundled agent type warrants a ban.
task.agentAccountPools, tier.subagent — no-op against keyless local endpoints.
PI_TASK_MAX_OUTPUT_BYTES / PI_TASK_MAX_OUTPUT_LINES — 500 KB / 5000 line defaults are sane.
before_subagent_spawn hook — programmable spawn policy; revisit if these caps prove insufficient.

Verification

cfg://task, cfg://providers/maxInFlightRequests reflect all rows above; persisted copies in agent/config.yml. Depth semantics confirmed against the shipped bundle, not just the setting description.
