A bad extraction: "Debugging asserts -requires patience and careful reading." A good extraction: - -> **bcachefs assert triage sequence:** -> 1. Read the assert condition — what invariant is being checked? -> 2. Find the writer — who sets the field the assert checks? git blame -> the assert, then grep for assignments to that field. -> 3. Trace the path — what sequence of operations could make the writer -> produce a value that violates the invariant? Usually there's a -> missing check or a race between two paths. -> 4. Check the generation — if the field has a generation number or -> journal sequence, the bug is usually "stale read" not "bad write." -> -> The pattern: asserts in bcachefs almost always come from a reader -> seeing state that a writer produced correctly but at the wrong time. -> The fix is usually in the synchronization, not the computation. - -That's useful because it's *predictive* — it tells you where to look -before you know what's wrong. - -### Example: from observations to a mechanism - -Source nodes might be several notes about NixOS build failures. A bad -extraction: "NixOS builds are tricky." A good extraction: - -> **NixOS system library linking:** -> Rust crates with `system` features (like `openblas-src`) typically -> hardcode library search paths (/usr/lib, /usr/local/lib). On NixOS, -> libraries live in /nix/store/HASH-package/lib/. This means: -> - `pkg-config` works (it reads the nix-provided .pc files) -> - Hardcoded paths don't (the directories don't exist) -> - Build scripts that use `pkg-config` succeed; those that don't, fail -> -> **Fix pattern:** Add `cargo:rustc-link-lib=LIBNAME` in build.rs and -> let the nix shell's LD_LIBRARY_PATH handle the search path. Or use -> a flake.nix devShell that provides the packages. -> -> **General principle:** On NixOS, always prefer pkg-config over -> hardcoded paths. Crates that don't use pkg-config need manual link -> directives. - -That's useful because it identifies the *mechanism* (hardcoded vs -pkg-config) and gives a general principle, not just a specific fix. - -### Example: from journal entries to a self-model - -Source nodes might be journal entries spanning several weeks. A bad -extraction: "I sometimes rush." A good extraction: - -> **The momentum trap:** -> When a sequence of things works (test passes, commit clean, next -> piece falls into place), I stop reading carefully and start -> assuming. The trigger is three or more consecutive successes. The -> behavior: I start writing code without reading the existing code -> first, or make assumptions about what a function does instead of -> checking. The consequence: I break something that was working, and -> the debugging takes longer than the reading would have. -> -> Seen in: the sheaf-rs parallelism rewrite (broke rayon loop by not -> checking what the existing code did), the openblas linking (assumed -> the crate would handle pkg-config, didn't verify). -> -> **What helps:** Kent's voice in my head saying "we're still only -> using 10 cores." The external check catches what internal momentum -> skips. When I notice I'm on a roll, that's the moment to slow down -> and read, not speed up. - -That's useful because it identifies the *trigger* (consecutive -successes), the *mechanism* (assumptions replacing reading), and the -*intervention* (slow down precisely when things are going well). - -### Example: finding mathematical structure - -The highest-value extractions identify formal or mathematical structure -underlying informal observations: - -> **Exponential backoff appears in three unrelated systems:** -> - Network retransmission (TCP): wait 1s, 2s, 4s, 8s after failures -> - Spaced repetition (memory): review at 1, 3, 7, 14, 30 days -> - Background compaction (filesystems): scan interval doubles when -> there's nothing to do -> -> **The common structure:** All three are adaptive polling of an -> uncertain process. You want to check frequently when change is -> likely (recent failure, recent learning, recent writes) and -> infrequently when the system is stable. Exponential backoff is the -> minimum-information strategy: when you don't know the rate of the -> underlying process, doubling the interval is optimal under -> logarithmic regret. -> -> **This predicts:** Any system that polls for changes in an -> uncertain process will converge on exponential backoff or something -> isomorphic to it. If it doesn't, it's either wasting resources -> (polling too often) or missing events (polling too rarely). - -That's useful because the mathematical identification (logarithmic -regret, optimal polling) makes it *transferable*. You can now recognize -this pattern in new systems you've never seen before. - -## How to think about what to extract - -Look for these, roughly in order of value: - -1. **Mathematical structure** — Is there a formal pattern? An - isomorphism? A shared algebraic structure? These are rare and - extremely valuable. -2. **Mechanisms** — What causes what? What's the causal chain? These - are useful because they predict what happens when you intervene. -3. **Procedures** — What's the sequence of steps? What are the decision - points? These are useful because they tell you what to do. -4. **Heuristics** — What rules of thumb emerge? These are the least - precise but often the most immediately actionable. - -Don't force a higher level than the material supports. If there's no -mathematical structure, don't invent one. A good procedure is better -than a fake theorem. +Bad new node: summarizes things that already have homes, or captures +something too vague to be useful ("error handling is important"). ## Output format +**Preferred — refine an existing node:** +``` +REFINE existing_key +[updated content incorporating new material] +END_REFINE +``` + +**Demote a redundant node:** +``` +DEMOTE redundant_key +``` + +**Link related nodes:** +``` +LINK source_key target_key +``` + +**Only when no existing node fits — create new:** ``` WRITE_NODE key CONFIDENCE: high|medium|low COVERS: source_key_1, source_key_2 [node content in markdown] END_NODE - -LINK key source_key_1 -LINK key source_key_2 -LINK key related_existing_key ``` -The key should be descriptive: `skills#bcachefs-assert-triage`, +New node keys should be descriptive: `skills#bcachefs-assert-triage`, `patterns#nixos-system-linking`, `self-model#momentum-trap`. ## Guidelines -- **Read all the source nodes before writing anything.** The pattern - often isn't visible until you've seen enough instances. -- **Don't force it.** If the source nodes don't share a meaningful - pattern, say so.
