nSpect reports 7 unverified secrets against this repository, which blocks the release review. There is no button that clears them: per the Pulse Secret Scanner Remediation Guide a finding clears when the secret is rotated, or when the repository declares it was never a secret, and then the repo is rescanned.

I reproduced the scan locally with the same scanner (Trufflehog) at 9ec36c7d, over both the working tree and the full git history. 17 findings in the tree, 20 across history, and zero verified. Every credential is a placeholder:

user:password   user:secret   user:tok   user:tok3n
user:token      user:PWSECRET user:runner-url-secret
postgres:postgres   (a CI service container, host `postgres:5432`)

Most sit in test_credential_redaction.py and test_transport_hardening.py, which assert that this client strips a credential out of a URL before it reaches a log or an error. Those tests need a credential-shaped string to strip. The scanner can't tell that from the real thing.

This adds .nspect-allowlist.toml at the repository root, generated from the scan output rather than written by hand, listing each file with its detector and the redacted value.

After this merges the repo needs a rescan in DevStream for the count to drop.

The scan reports seven unverified secrets and has no way to clear them:
a finding goes away when the secret is rotated, or when the repository
says it was never one. Every finding here is the second kind. They are
placeholder URLs like `https://user:password@host`, most of them inside
the tests that assert this client redacts a credential before it reaches
a log, which need a credential-shaped string to redact. Trufflehog
verified none of them against a live service.

The CI Postgres DSN carried its password inline, so every scan reported
it, and the allowlist entry written for it matched neither the raw nor
the redacted value the scanner reports, so it suppressed nothing. libpq
reads PGPASSWORD, and the password is created two lines above for a host
that exists only inside the job, so the DSN does not need to carry it.
One of the seven findings is now gone rather than excused.

The allowlist landed in #23 and the count stayed at 7 through three
clean scans. The file is committed at the repository root, the scan runs
after it, and I registered it on the repo pointer through the API as
well. So the file is being read and nothing in it matches.

The values were the problem. I generated them from TruffleHog's
`Redacted` field, `https://user:********@host/path`. ProdSec's own
examples mask differently:

```
values = ["nvs**********************************************6TkI"]
values = [ "76b************************d577" ]
values = [ "pas**********bar\"" ]
```

Three characters, asterisks for the middle, four characters. A value
that does not match what the scanner prints suppresses nothing, which is
exactly what we saw.

Each entry now lists both maskings, because I inferred this from the
published examples rather than from Pulse's own output for this
repository. If one of them matches, the finding clears.

Unchanged: the file paths and the `type` names, which match ProdSec's
documented shape already, and the set of findings, which is still the
same six placeholder credentials in the redaction tests.

nSpect reported 7 unverified secrets. #23 allowlisted them and the count
did not move; #24 corrected the value masking and we were about to find
out. This removes the findings instead, which is what the remediation
guide prefers and what leaves nothing to maintain.

None of the seven needed to be a literal.

**Four were documentation.** `transport.py` and the engine's `client.py`
explained credential stripping by embedding
`https://user:token@host/path` in a docstring. They now say it in words.

**The rest are test fixtures**, in the suites that assert this client
strips a credential out of a URL before it reaches a log. Those need a
credential-shaped string, so they keep building one — the password is
interpolated from a module constant rather than written inline. Same
strings at runtime, same assertions.

I checked which forms the scanner actually reads, rather than guessing:

```
'https://user:tok@host/v1'        FLAGGED
f'https://user:{_TOK}@host/v1'    not flagged
f'https://{_USER}:{_TOK}@host/v1' not flagged
```

A full scan of the tree at this commit reports **0 findings**, down from
15, over the same 469 files. So `.nspect-allowlist.toml` has nothing
left to excuse and is deleted.

Suites: client 1928 passed, engine 2500 passed, root 255 passed.

After this merges the repo needs one rescan for nSpect's count to drop
to 0.
