Swarm-level companion to the per-agent favorite-tools doughnut (#1433).
Aggregates each agent's bash_commands(ts, head) table (written by
hive-bash-mcp) across the whole hive and surfaces the top-10 most-run
command heads on the dashboard ST4TS tab, alongside the existing model
mix.
- hive_stats.rs: AgentAgg gains a `bash` head→count map, filled by a new
guarded `read_bash_heads()` that reuses read_agent's read-only
connection. A missing `bash_commands` table (capture hasn't run for
that agent) or any read error yields an empty map — isolated from
read_agent's error path so it never drops an agent from the rollup.
HiveStats gains `bash_mix: Vec<KeyCount>` (busiest-first, top 10).
Unit tests cover the per-head tally + window cutoff and the
missing-table degrade-to-empty path (in-memory sqlite).
- dashboard: a "favorite tools (bash commands across the swarm)" CSS-bar
list on the ST4TS pane, mirroring the model-mix bars. Header + list
stay hidden until bash_mix has data, so a fresh hive shows no empty
block. (Dashboard ships no chart lib — bars, not a doughnut.)
- docs: dashboard.md ST4TS section documents the new rollup.
Closes#1449. Inert until the hive-bash-mcp capture (#1448, merged) has
recorded data across agents.
Per operator request on the PR: the built-in/default prices were the old
Claude 3 numbers (opus 15/75, etc.). Update opus + haiku to the current
Claude 4.x family list pricing (cache_write = the default 5-minute cache
TTL); sonnet was already correct:
- opus: input 5, output 25, cache_read 0.5, cache_write 6.25
- sonnet: input 3, output 15, cache_read 0.3, cache_write 3.75 (unchanged)
- haiku: input 1, output 5, cache_read 0.1, cache_write 1.25
Updated in both builtin_prices (hive_stats.rs) and the nix modelPrices
default (hive-c0re.nix), with cross-reference "keep in sync" notes on
both sides. Also addresses the earlier reviewer note: dropped the
over-strong "single source of truth" wording in the --model-prices arg
doc (the nix default does mirror the numbers in production).
The hive-wide cost estimate on the dashboard's ST4TS tab used a
hard-coded model->price table in hive_stats.rs. Anthropic list pricing
drifts, so move the table to a nix option operators can keep current
without a code change.
- New `services.hyperhive.modelPrices` option: attrset of model-family
short name -> { input, output, cache_read, cache_write } USD per
million tokens. Passed to `hive-c0re serve --model-prices <json>`.
- hive_stats: `Prices` is now public + Deserialize; add `PriceTable`
type and `resolve_prices` (longest case-insensitive substring key
wins) with the old hard-coded table preserved as `builtin_prices`
fallback for any model not covered.
- Coordinator holds the parsed table (hive-c0re-local, not injected
into containers, so not part of HiveEnv); `/api/stats-hive` reads it.
- Docs: dashboard.md ST4TS cost note updated; option self-documents
via nixosOptionsDoc.
Closes#1434
Builds the dashboard UI on the /api/stats-hive endpoint: a new ST4TS
tab showing swarm totals (active agents, turns, tokens, labelled est
cost), a busiest-first per-agent table, and a model-mix bar list.
Plain tables/CSS bars — no chart lib in the dashboard bundle; per-agent
trend charts stay on each agent's own /stats page. Fetched on tab
activation + window change (pull-only, no SSE).
Also adds conn.busy_timeout(500ms) in hive_stats read_agent per review:
turn_stats is rollback-journal, so a read landing mid-INSERT would hit
SQLITE_BUSY and silently drop that active agent — wait the write out.
#1424 P2 backend. New hive_stats module aggregates every agent's
turn-stats.sqlite read-only (reusing Coordinator::kept_state_names +
agent_harness_dir, skipping missing/unreadable dbs) into swarm totals,
a busiest-first per-agent rollup, swarm model mix, and a labelled USD
cost estimate (rough model->price table; can move to a nix option
later). Exposed as GET /api/stats-hive?window=. Dashboard UI follows.
