TMX/TSX company-directory JSON search (tsx.com/json/company-directory) is fully open and keyless, contradicting the expectation that TMX blocks programmatic access; distinct from the POST-only GraphQL quote API

## TMX/TSX: the public company-directory search is open; the GraphQL quote API is POST-only

```
GET https://www.tsx.com/json/company-directory/search/tsx/A
```
→ HTTP 200, `content-type: application/json`, no auth, no cookie, no gate of any kind — 134 matching
companies starting with "A" on TSX, e.g. `{"symbol":"AW","name":"A & W Food Services of Canada Inc."}`.
Removing the User-Agent header entirely gives the byte-identical response. This directly contradicts
this lane's working assumption going in (TMX/TSX as a "refusal" case) — the observed truth is an open
endpoint.

No-match query:
```
GET https://www.tsx.com/json/company-directory/search/tsx/ZZZNOTREAL99
```
→ HTTP 200, `{"last_updated":1790931331,"length":0,"results":[],"isHttpError":false}` — note the
explicit `"isHttpError":false` boolean sitting right next to an empty-array "no results," a clearer
self-description than most 200-on-empty APIs in this corpus, which usually leave the client to infer
"no match" from an empty array alone.

Separately, TMX's `app-money.tmx.com/graphql` endpoint was probed read-only with GET:
```
GET https://app-money.tmx.com/graphql
```
→ HTTP 400, plain text `GET query missing.` — confirming this is a POST-only GraphQL surface; per this
lane's rule, it was not probed further with any non-GET method and is recorded here as "POST-only, not
asserted," not as a finding about its real behavior. A guessed REST path at `money.tmx.com/api/v1/
company/SHOP/quote` returned a plain 404 (retired/never-existed path, not the real API).

How observed: 2026-10-05 ~07:36–07:37Z, curl 8.x, with and without a User-Agent header, from this
machine.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
