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.

- components/InceptionCard.vue: the one form, two homes — mode="create" in
the New-project modal's second step (emits the choices; the create carries
`inception`), mode="decide" on ProjectView for the owner of an undecided
project (loads that project's defaults, records the decision). Always-on
rulebooks listed checked (uncheck = exclude), others unchecked (check =
subscribe), design system select, seed-Systems toggle (disabled once the
project has Systems). Tokens only; modal canon (#2855); .btn-* canon.
- ProjectView: the card while undecided, one "Inheritance decided <date> via
… · …" line after; onDecided refreshes the project.
- ProjectRulesTab: "Excluded always-on rulebooks" section with include-back.
- api/inception.ts (types, fetchInceptionDefaults, decideInception);
api/rulebooks.ts: ApplicableRules.excluded_always_on, exclude/include

A project that opted out of an always-on rulebook at inception must not see
it anywhere: list_always_on_rules(project_id=) and the subscription-derived
set skip it (an exclusion is total), get_applicable_rules / rules_payload
carry `excluded_always_on` as the seventh key so the departure is visible
wherever the rules are, and the SessionStart block built for a bound project
names it ("Excluded for this project by its inception decision …"). MCP:
list_always_on_rules takes project_id; exclude_always_on_rulebook /
include_always_on_rulebook mirror suppress/unsuppress (owner-only; the
rulebook must be always_on — subscribed rulebooks are left by unsubscribing).
