bvandeusenandClaude Opus 5	2ee24b9d2b	feat(rules): rules before tools — a PreToolUse arm keyed on the action (#3476) ... The only just-in-time rule surface was registered on `Write|Edit` and queried with `code or path`, so a rule could be retrieved at the moment of a code write and nowhere else. Every rule about which tool to reach for — don't curl the forge, don't stand up a stack, don't run the suite locally, don't branch — was unreachable exactly when it mattered, and residency in the always-on preload was the only surface it had. That is the pressure that grew the resident set to 31 against #3089's ceiling of ~23; it was never a judgment anybody made. A reflex generates no query, so an instruction to check the rules cannot catch one. A mechanical trigger can: the tool call IS the query, and a reflex has to become a tool call before it can do anything. `build_tool_rule_hint` is deliberately tool-agnostic — a name and a string — so widening the matcher later is a hooks.json edit with no server change. The hook starts on Bash, which is where the action reflexes live. The two pre-tool arms share ONE session ledger of already-named rules (`<state>/<sid>.rules.ids`). Two ledgers would mean a rule named by one arm gets re-offered by the other, and the hint that fires most often is exactly the one that must not repeat itself. A test asserts both scripts build the same path, and another checks the shell hook and the Python route agree on every query-arg name (rule 33) — a rename there fails silently, looking like a surface that never finds anything rather than a broken one. Deliberately silent on outage, unlike the prior-art hook: a write is occasional, a Bash call is not, and an outage line before every command is what gets a channel muted. `tier="conditional"` matches the write arm and is the transition point — an always-on rule is already resident, so re-tier one and it starts arriving here instead of in every session's preamble. `pre_tool_rule` joins RANKED_SOURCES: this arm chose what it showed, so a pull can settle whether the choice landed.

bvandeusenandClaude Opus 5	8b9b3a1d9b	feat(telemetry): the preload emits, and the always-on set stops being unfalsifiable (#3473) ... The ranked rule arm became measurable in M333. The preload did not — and that is the surface whose value is actually in question. `list_always_on_rules`, the SessionStart block and every `rules_payload` caller handed rules over wholesale and emitted nothing, so the resident set's token cost was certain and its usefulness could not be tested even in principle. Bulk deliveries now record as AMBIENT, beside the ranked count and never inside pull-through. Folding them in would mean growing the always-on set depressed the arm's measured precision and trimming it flattered the arm, neither for any reason to do with the arm. `RANKED_SOURCES` inverts the note twin's `AMBIENT_SOURCES` deliberately: there is one ranked rule source and this change adds seven bulk ones, so naming the rare half makes a forgotten surface default to ambient — under-counting it — rather than padding the denominator with surfacings nobody chose. Two lookalike call sites are deliberately left silent, with a test to keep them that way: the write-path etag arm and `rules_etag_for` read the rules to build or compare a MARKER and show nobody anything. No migration — `event` and `source` are plain Text with no CHECK (rule 36 does not apply). Snippet #2858 updated to the new `rules_payload` contract.
