84 files spanning provider capabilities, model routing, headless
runtime, sf auto subsystems, gitbook docs, and test coverage. Snapshotted
so headless auto can resume M004 (Production Readiness) S03
(Verification Gate Validation) on a clean tree.

Caveman skill (output compression) installed at ~/.claude/skills/caveman/
and activated for dr-repo. Two follow-ups for INPUT-side compression
remain — sf's own prompts are verbose (execute-task alone has 10-step
instructions, runtime context, multiple inlined plans), and that's paid
on every dispatch:
- Tier 2 (1-2 days): Manually rewrite heaviest prompt sections in
caveman style. Preserve intent + nuance, drop fluff. Compare against
current to confirm no quality regression.
- Tier 3 (3-4 days): Runtime input preprocessor — pipe rendered prompt
through caveman-compress (sub-skill, ~46% reduction) before dispatch.
Behind a terse_prompts: true flag. Adds drift risk vs authored intent;
needs comparison harness.

Adds step 0a: when independent reads/greps are needed, batch them in a
single assistant turn instead of one-at-a-time. The existing step 0
already pushed for terse narration, but didn't address the bigger waste
— sequential tool calls when parallel would work. Common case: reading
handler + test + schema to triangulate a bug — three reads in one turn,
not three turns.
Also nudges away from "talking-then-doing": if the next action is
unambiguous, just take it. Describing intent before every call is the
dead weight that adds up to 30-50% extra round-trips.
Behavior fix only (prompt-level). Model can still narrate inside its
thinking channel since that's a model property; this targets the
chat/tool-use channel where the user pays per turn.

The single IDLE_TIMEOUT_MS constant was conflating two different jobs:
"are we done?" vs "is the agent stuck?". For multi-turn commands (auto,
next, discuss, plan), the first question is wrong — those signal
completion explicitly via "auto-mode stopped" terminal notifications,
and child-process exit catches crashes. The 120s I'd just bumped
multi-turn to was still in idle-detection mindset; that's not what we
need from this timer.
New semantics:
- IDLE_TIMEOUT_MS = 15s — quick commands (status, queue, …); idle
really does mean done.
- NEW_MILESTONE_IDLE_TIMEOUT_MS = 120s — bounded creative task with
pauses for thinking between bootstrap steps.
- MULTI_TURN_DEADLOCK_BACKSTOP_MS = 30 minutes — auto/next/discuss/plan.
Not a "done" detector; a deadlock recovery bound. Long enough to
never bother slow LLM reasoning or chained tool calls; short enough
to recover from a true hang within a reasonable window. Real
completion comes from terminal notifications + child-process exit,
both already wired.
Code reads cleaner too: effectiveIdleTimeout selection now mirrors the
three-way conceptual split.

The 15s IDLE_TIMEOUT_MS was killing auto-mode prematurely. Symptom: sf
headless auto would dispatch a task, the LLM would make 1-2 tool calls,
pause to reason about the next step, exceed 15s of "no events", and
headless would declare "Status: complete" — exiting at ~35s with the task
barely started (123 events but only 2 tool calls).
The 120s NEW_MILESTONE_IDLE_TIMEOUT_MS already exists for the same reason
("LLM may pause between tool calls e.g. after mkdir, before writing
files"). The same applies to auto/next/discuss/plan — all multi-turn
commands where the LLM thinks longer between actions, especially on
non-trivial tasks. isMultiTurnCommand was already defined for related
logic; this just wires it into the idle-timeout decision.

bun was the wrong runtime for our environment, two ways:
1. bun doesn't ship node:sqlite. sf-db.ts falls back through node:sqlite
→ better-sqlite3 → null. Result: 'No SQLite provider available' and
degraded-mode filesystem-state derivation, even though sqlite is
actually available (node:sqlite under node, bun:sqlite under bun —
both valid, but our code only knows the node names).
2. bun's loader doesn't inherit the system library search path under
Nix. libz.so.1 isn't found for forge_engine.node, so the native
addon falls through to JS implementations (slower).
Both warnings ("Native addon not available", "DB unavailable —
degraded mode") were the symptom of "we're running under bun".
Fix: use node + the existing src/resources/extensions/sf/tests/
resolve-ts.mjs loader hook (which already handles .js → .ts
import-specifier remapping for runtime resolution) +
--experimental-strip-types (node 22+, native in 24).
Result: from-source via node loads cleanly. No native warning.
No sqlite warning. No degraded mode. Exec: `./bin/sf-from-source
--print "..."` returns the model output and nothing else.
Drops the LD_LIBRARY_PATH zlib-injection hack that was added in
4912f6ea8 — that was working around the bun native-loader issue
that doesn't exist under node.
