*
* A busy lock always resolves, by one of two routes:
* - a live peer holds it, and releases when its command finishes;
* - the holder is already dead and the operating system has not finished
* reclaiming the lock yet.
*
* The second route is Windows-specific and is why this wait needs room. On POSIX
* the kernel drops flock the instant the owner dies. Windows byte-range locks do
* not work that way: Microsoft documents that after a process terminates holding
* one, "the time it takes for the operating system to unlock these locks depends
* upon available system resources", and that until then "access to these files
* may be denied". A loaded CI runner is precisely where those resources are
* scarce, and `tests/windows/test_daemon_stability.py` manufactures the situation
* deliberately — it hard-kills daemons with `taskkill /F`, including a crash
* recovery section, so the next client meets a lock whose owner no longer exists.
*
* Waiting was previously capped at MAIN_STARTUP_TIMEOUT_MS (10s), which let a
* clock decide a user-visible outcome: a command was refused with "coordination
* remained busy" while the only thing wrong was that the OS had not yet swept up
* after a killed process. Since both routes above terminate, the correct response
* to busy is to keep waiting; the ceiling below is a backstop against a peer that
* never finishes, not a budget for healthy contention. Clean exits already

/*
* pass_importance.c — Index-time per-symbol importance score (weighted degree).
*
* Predump pass. Computes an importance score for every Function/Method/Class
* node and stores it as a numeric "importance" key inside the node's EXISTING
* properties_json blob — no new column, no schema change, and therefore no
* CBM_INDEX_FORMAT_VERSION bump. Indexes written by older builds simply lack
* the key; every consumer must tolerate its absence.
*
* Model (weighted degree, Aider-repomap shaped):
*
* importance = sqrt(num_refs) * priv * generic * distinct * test_penalty
*
* num_refs incoming CALLS + USAGE edges. 0 -> sqrt(0) = 0.
* priv 0.1 name is private (leading underscore)
* generic 0.1 the name is defined in >= 5 DISTINCT files
* distinct 10 name is snake_case or camelCase AND len >= 8
* test_penalty
* 0.1 the symbol is test scaffolding — either the target of an
* incoming TESTS edge (a production helper exercised by a
* test), or it lives in a test file per the graph's own
* canonical cbm_is_test_path() classifier (the same one
* pass_tests uses).
*
* Transitive importance (PageRank) is deliberately NOT built here: weighted
* degree is what this pass claims, and a transitive refinement has to earn
* itself against a fixed judgment set before it ships.
*
* ── Cost ─────────────────────────────────────────────────────────────
* The generic-name multiplier needs |{ file a name is defined in }|. The
* obvious shape — for each node, walk its whole same-name group and
* pairwise-compare file paths — is O(k^2) per node and therefore O(k^3) per
* same-name group of size k. That is not a theoretical concern: on a large
* Java corpus a single name group (`toString`, k≈4.6k) costs ~2 minutes, and
* a handful of such names alone multiplies total index time several-fold.
*
* This implementation is linear in the graph instead:
* - the distinct-file count is computed ONCE PER DISTINCT NAME and memoized
* (g_imp_name_counts), so a group of size k is scanned once, not k times;
* - within a group, file paths are deduplicated through a hash set rather
* than pairwise strcmp.
* Total distinct-file work is therefore Σ over distinct names of k = O(N).
* Both gbuf lookups it rests on (find_by_name, find_edges_by_target_type) are
* hash-indexed, so the per-node loop is O(1) amortised per node.
*
* g_importance_name_visits counts same-name-group member visits and is GATED
* in the complexity suite: it must stay linear (ratio ~2) under a corpus
* doubling. A regression to the per-node scan lands at ~4 and fails the gate.
*
* ── Ordering (load-bearing) ──────────────────────────────────────────
* Registered LAST among the predump passes, and last in the incremental
* post-pass sequence, so every edge type the score reads (CALLS, USAGE from
* extraction; TESTS from pass_tests) already exists. A pass ordered earlier
* would silently score everything at num_refs = 0 with no test penalty.

* graph in RAM: cbm_delta_preseed fills the delta gbuf with *proxy* nodes
* (id, label, name, qn, file_path — no edges, empty properties), and only the
* re-extracted files' symbols carry real edges. Scoring there reads a
* near-zero in-degree for a symbol referenced hundreds of times project-wide,
* and cbm_delta_patch then persists exactly those fresh rows. Loading the full
* graph to fix that would give back the point of the delta route, so the
* recompute runs where the complete graph already exists: in SQL, over the
* staging store, AFTER cbm_delta_patch has inserted the new nodes and
* re-linked the snapshotted inbound edges.
*
* WHY IT CANNOT DRIFT FROM THE IN-MEMORY PASS. The scoring rule and the JSON
* write-back are not reimplemented here. They are registered as SQLite
* user-defined functions that call cbm_pipeline_importance_score() and
* cbm_pipeline_importance_set_prop() — the same C code the gbuf pass runs.
* SQL supplies only the three aggregates (in-degree, TESTS presence, distinct
* files per name), each one indexed GROUP BY. What remains free is the
* GATHERING, and the full-vs-incremental equivalence test guards that.
*
* The whole project is rescored, not just the changed files: distinct-files-
* per-name is a global input, so editing one file can legitimately move a name
* across the generic-name threshold for every other definition of that name. A
* scoped recompute would leave those stale — and would fail the equivalence

* keywords and generic arguments, but it cannot know WHERE the name is
* declared. The Python and TS cross-file registrars, however, consume

* nothing declared in ANOTHER file: `class Child(Base)` in child.py never
* saw Base in base.py, so a call to an inherited method through a typed
* receiver had no member to find and fell through to the weak textual
* cascade (where the #592/#606 guard correctly kills it).
*
* Resolve each base name ONCE per definition here, from exactly the
* inputs pass_semantic uses to draw its INHERITS edge: the project
* registry, the declaring module, and the file's import map. Two
* properties follow. The LSP's inheritance view is the same relation the
* graph records, so the two cannot diverge. And the binding is
* import- or same-module-backed, not a short-name guess, so the CALLS
* edge it enables is a supported fact that the weak-member guard keeps.
*
* Cost: O(defs) hash lookups + ONE import map per file. No per-call-site
* hierarchy walk, no registry scan, no per-file registry rebuild.
