#3156 sampled the TS inventory and said the conversion is *"the six LANE
Drizzle sites plus whatever small TS remainder is neither a fallback arm
nor a sentinel"*.
**That remainder is zero.** I left three sites unchecked when I wrote
it. All three are fallback arms:
| site | shape |
|---|---|
| `live-agent-count.ts:164` | `task.columnTerminalKind ?? (task.column
=== "done" ? … )` — the resolved value wins via `??` |
| `store.ts:1972` | `if (!lanes) return dep.column !== "done" && …` — an
explicit no-metadata branch |
| `branch-and-pr-entities.ts:525` | `lanes === undefined ? task.column
=== "archived" : task.column === lanes.archived` |
With the previously classified entries, **every** site in
`AUDITED_TS_SITES` is now accounted for as a fallback arm, a
STATE/sentinel comparison, or a converted guard's retained literal.
**None is an unconverted LANE guard.**
## So the cluster is done
"52 sites across three encodings" is fully triaged, and the convertible
work is the six Drizzle LANE sites plus the log-entry gate — all
additive, so the inventories never moved.
What the gate now protects is a population of **fallback arms and STATE
markers**, which is exactly what it should protect: each is the
documented answer for a caller that supplies no resolved set, or a
marker that must never be resolved.
A future **drop** in any of the three counts means someone removed a
fallback or converted a STATE site — both regressions. That is the check
this file was built to make, and is now the only check it needs to make.
## Enumerated, not sampled
I sampled this inventory twice and each pass changed the size estimate —
first "52 sites, real blast radius", then "six plus a small remainder".
A third estimate would have been worth less than a complete count, so
this pass covers every entry.
That is the honest close: the number stopped moving because I stopped
guessing at it.
## Measured
- Comment-only; parity test **2/2**.
- `tsc --noEmit -p packages/core` clean; census `--strict` clean. **No
census movement.**
