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.

Companion to the earlier schema-versioning framework. Where that handles
data-shape evolution via forward migrations, this handles file-template
evolution via silent self-rewrite. The user shouldn't have to know:
- ensurePreferences() now stamps `last_synced_with_sf: <semver>` in the
frontmatter when seeding a new project's PREFERENCES.md, recording the
sf version that wrote the template.
- New module preferences-template-upgrade.ts:
- detectTemplateDrift(prefs) — pure check, returns
{ fromVersion, toVersion, needsUpgrade }.
- upgradePreferencesFileIfDrifted(path, prefs) — silently re-renders
the file's frontmatter when fromVersion ≠ toVersion. Body (anything
after the closing `---`) is preserved verbatim, so user notes stay.
- Wired into loadPreferencesFile() — every read self-aligns. No human
warnings, no opt-in flow; sf keeps its own house in order.
- last_synced_with_sf added to SFPreferences + KNOWN_PREFERENCE_KEYS so
it round-trips through validatePreferences without "unknown key"
warnings.
Failure modes are non-fatal: missing file, malformed frontmatter, or
read-only filesystem all leave the file alone and return the in-memory
prefs unchanged. SF_VERSION env var (set by loader.ts) is the source of
truth for "current sf"; "0.0.0" sentinel skips upgrade so atypical entry
points don't stamp incorrect values.

bun's loader doesn't inherit the same library search path as node under
Nix, so require('forge_engine.linux-x64.node') fails with
'libz.so.1: cannot open shared object file' even when the native addon
exists at the expected path. Result: sf-from-source ran in
JS-fallback mode, and we'd been working around it by switching to
node dist/loader.js — which forces a manual `npm run copy-resources`
after every src/ change to keep dist in sync.
This wraps sf-from-source to find a Nix-store zlib at startup and
prepend it to LD_LIBRARY_PATH before exec'ing bun. The native addon
loads cleanly; from-source becomes the reliable default again; no
more dist drift to worry about.
Find pattern: /nix/store/*-zlib-*/lib/libz.so.1 at maxdepth 4
(maxdepth 2 was too shallow — the hash dir is depth 1, lib is depth 2,
the .so.1 file is depth 3, plus we want the parent dir for
LD_LIBRARY_PATH so '%h' on a depth-3 match gives the lib dir).
Outside Nix (no /nix/store), this is a no-op and falls through to
the existing exec.

ensureGitignore was re-adding `.sf`, `.sf-id`, `.bg-shell/` to the project's
.gitignore on every sf run, causing two issues:
1. Working-tree churn — every invocation dirtied .gitignore, forcing a
commit just to silence "uncommitted changes" warnings. Pattern flagged
by user: "is this the right way with its own every run".
2. False-positive duplicate-add — the literal-string check
(`existingLines.has(".sf")`) didn't recognize user-equivalent patterns
like `/.sf` (root-only) or `.sf/` (with trailing slash), so an explicit
user entry got duplicated by the auto-add on next run.
Fix: move sf-specific runtime patterns to `.git/info/exclude` via new
`ensureGitInfoExclude()`. That file is per-clone (not committed), so
re-writing is invisible to git status. The project's `.gitignore` stays
human-curated and sf doesn't opinionate on it.
`ensureGitignore()` now calls `ensureGitInfoExclude()` first so callers
don't need to update — backwards compatible. Generic OS/IDE/lang patterns
(.DS_Store, node_modules/, target/, etc.) stay in BASELINE_PATTERNS for
.gitignore since those genuinely belong in version control.

We sync from two upstreams (pi-mono via cherry-pick, gsd-2 via manual
port) and the gsd-2 syncs hit naming/path translation every time.
This guide makes the translation rules explicit and persistent so
future ports (by humans or by sf) don't have to rediscover them.
Covers:
- The naming translations table: gsd_* → sf_*, .gsd/ → .sf/,
extensions/gsd/ → extensions/sf/, @sf-run/* → @singularity-forge/*,
GSD_HOME → SF_HOME, etc.
- Default rule: translate naming, keep substance. Includes the
cautionary tale of my own self-heal rejection (1bbd20bf7) where I
wrongly skipped a fix because of the path string.
- When a port REALLY doesn't apply (architectural divergence vs naming
divergence) — three categories with examples.
- Mechanics for pi-mono (cherry-pick) vs gsd-2 (manual) ports.
- Skip-list documentation: when you reject, document why in BUILD_PLAN
with the upstream SHA and reason.
- Prompt-edit handling: gsd_<verb> → sf_<verb>, register tools before
porting prompt edits that call them.
Future automation hint at the bottom for a port-translation script.

Earlier I (and sf parroting BUILD_PLAN.md) dismissed gsd-2's symlinked
.gsd self-heal fix (9340f1e9b / #4423) as 'doesn't apply because we use
.sf instead'. That was a superficial read.
The fix is about detecting and recovering from a broken/redirected
staging-dir symlink to prevent silent data loss. The .gsd/ vs .sf/ is
a one-line path translation, not a design difference. The
symlink-resilience logic is exactly what we need for our staging.
Path-translate .gsd/ → .sf/ in the port. The substance ports.

The wrapper imposed CPUQuota=200% / MemoryMax=4G via a transient scope
unit, which requires polkit interactive auth and silently failed on
non-TTY hosts (the script then exit-0'd without running tests). The
limits were a guard against the heavy test:coverage runner's worker
saturation, but test:sf-light already runs in-process with
--max-old-space-size=2048 and --test-timeout=30000 — the systemd
governor was overkill for this lighter target and incompatible with
headless / non-laptop environments.
