assert_remote_update_trigger polls drydock's unversioned /api/containers and
/api/triggers/docker/update. Those became 410 tombstones in drydock v1.6.0
(app/api/index.ts sendUnversionedApiTombstone, and that repo's
DEPRECATIONS.md); the versioned /api/v1/... paths are the live ones.

The failure was invisible because of how the 410 got handled. curl 2>/dev/null
hid the transport side, the 410 JSON error body flowed straight into
jq '.data // .', .name on that string raised a jq type error, and a second
2>/dev/null discarded that too. What came out was an empty result, which is
exactly what a genuine store-sync failure produces. The two are indistinguishable
from the outside, so the harness reported "sentinel never appeared in drydock's
store" and the bisect pointed at drydock.

That's how CodesWhat/drydock#802 got filed as a shipped regression in 1.6.x and
sat for about a month. Verified by hand against a live 1.6.0-rc.1 + portwing
0.9.6 stack: /api/containers returns 410, /api/v1/containers returns the
inventory. Nothing was ever wrong with drydock. My misattributing comments on
sockguard#289 are corrected there.

What changed

Both calls move to /api/v1. drydock 1.5.2, the legacy-floor pin, mounts the
same router at both /api/v1 and /api (app/api/index.ts:135 and :139), so
the versioned form works on every row in the matrix, not just the current ones.

Beyond the path fix, the probe checks the HTTP status with
--write-out '%{http_code}' before handing anything to jq, and records an explicit
harness error, not a conformance failure result naming the status and the
response body on any non-2xx. A jq failure likewise reports the parse error and
the body instead of returning empty. So the next time this class of break
happens it fails on the spot with its own message rather than decaying into a
"sentinel never appeared" timeout six minutes later.

A non-2xx fails immediately rather than retrying to the deadline. That is
deliberate and it is safe here: assert_auth_handshake has already waited up to
90s for drydock to log the portwing agent authenticating, against the same
express app that serves this route, so warm-up is over by the time assertion 8
runs. A 5xx-is-transient carve-out would re-hide exactly what this branch exists
to surface. Transport-level curl failures (connection refused, timeout) still
retry as before, since those genuinely are the "no response at all" case.

Verification

Dispatched the conformance workflow on this branch rather than trusting the
reasoning: https://github.com/CodesWhat/sockguard/actions/runs/32316538637. No PR
check exercises this path, so a green PR here proves nothing about the fix.

Fixes: #289
Refs: CodesWhat/drydock#802

Changelog

  • 🔧 Changed conformance checks to use /api/v1/containers and /api/v1/triggers/docker/update.
  • 🔧 Changed container polling to process paginated {data: [...]} responses.
  • 🐛 Fixed failures caused by deprecated unversioned endpoints in drydock v1.6.0.
  • 🔧 Changed probe handling to fail immediately on non-2xx responses and jq parse errors.
  • 🔧 Continued retries for transport-level curl failures.
  • 🔧 Updated Assertion 8 documentation and timeout messages.
  • 🔧 Preserved compatibility with the drydock 1.5.2 legacy-floor pin.

Concerns

  • Verify that agent-qualified trigger paths are correctly encoded for all supported agent names.
  • Verify that pagination polling does not miss the expected container across pages.
  • Add or update conformance tests for non-2xx responses, malformed JSON, and transport failures.

📝 Walkthrough

Walkthrough

Assertion 8 now uses Drydock’s versioned /api/v1/containers and /api/v1/triggers/docker/update endpoints. Container polling reads the paginated {data: [...]} response. The harness retries transient curl failures, but fails on non-2xx responses and invalid JSON. Timeout messages and documentation now reference the versioned API.

…errors

assert_remote_update_trigger polled drydock's unversioned /api/containers
and /api/triggers/docker/update, which 410 as of drydock v1.6.0 (see that
repo's DEPRECATIONS.md). The 410 body got fed straight into jq, whose type
error on the error object was silently discarded by 2>/dev/null, so the
assertion decayed into the same empty-result timeout a real store-sync
failure produces -- indistinguishable outcomes that misreported a harness
bug as a drydock regression (CodesWhat/drydock#802) for about a month.
Nothing was ever wrong with drydock.

Point both calls at /api/v1, check the HTTP status explicitly before
handing the body to jq, and surface jq parse failures instead of
swallowing them, so a harness bug now fails immediately with its own
message instead of decaying into a "sentinel never appeared" timeout.
drydock 1.5.2 -- the legacy-floor pin -- mounts the same router at both
/api/v1 and /api, so the versioned form works on every row in the matrix.

A non-2xx fails immediately rather than retrying to the deadline:
assert_auth_handshake has already waited up to 90s for drydock to log the
portwing agent authenticating against the same express app, so warm-up is
over by the time this runs and a retry would re-hide the error.
Transport-level curl failures (connection refused, timeout) still retry as
before, since those really are the "no response at all" case.

Approved.

CodeRabbit review on #294. `.data[]?` swallows a missing, null, or scalar
`.data` and returns an empty result with exit 0, so a 2xx error envelope
would still decay into the "sentinel never appeared" timeout this branch
exists to stop. Require `.data` to be an array and error by name when it
isn't. An empty array is untouched: that's the ordinary not-synced-yet
state and still polls to the deadline.

Also narrows the README's envelope claim from "every drydock version" to
the two the matrix actually exercises, the legacy-floor 1.5.2 pin and the
release the current-* rows resolve.
…fusal

The /api/v1 fix let assertion 8 reach the trigger step for the first time
in a month, which exposed the next difference. drydock 1.5.2 refuses a
correctly-shaped POST to an unconfigured docker update trigger with 404
"trigger not found"; 1.6.x gets one step further, evaluates the container,
and refuses with 400 "No update available for this container". Both are
the audited bundle's documented boundary, and 1.6.x reaching the
evaluation proves it accepted the request shape, which is what this
assertion is actually checking.

Confirmed on a dispatched run: legacy-floor (drydock 1.5.2) passes on 404,
current-standard and current-edge both reach the trigger and get the 400
body above. The sentinel now syncs on every row, which is the part that
was broken.

Match on the response body, not on a drydock version, so the assertion
stays version-agnostic and drydock's other 400 -- "Invalid trigger request
body", a real shape regression -- still fails.

Conformance run on this branch is green on all three rows: https://github.com/CodesWhat/sockguard/actions/runs/32317295410

success  Harness self-test
success  current-standard
success  current-edge
success  legacy-floor
success  Summary

Two runs, and the first one is the interesting one. 32316538637, against just the /api/v1 path fix, came back with legacy-floor passing and both current-* rows failing at a different step:

FAIL: remote-update-trigger -- trigger invocation was refused 400 -- the request
shape regressed (want the unconfigured-trigger 404/501);
body: {"error":"No update available for this container"}

The sentinel synced on every row, which is the part that was broken for a month. The path fix worked, and reaching the trigger step for the first time is what exposed the next difference: drydock 1.5.2 refuses an unconfigured trigger 404 "trigger not found", 1.6.x gets one step further, evaluates the container, and refuses 400 "No update available for this container". Both are the audited bundle's documented boundary, and 1.6.x reaching the evaluation at all proves it accepted the request shape, which is what this assertion is really checking. Handled in 26b6112, matched on the response body rather than on a drydock version so drydock's other 400 -- "Invalid trigger request body", a genuine shape regression -- still fails.

Nothing here is a PR check. No gate in this repo exercises assertion 8, which is the whole reason it rotted quietly, so the dispatched run is the evidence rather than a green tick on this page.

…es to main (#298)

Promotion of dev/v1.7 into main.

#294 / #299 -- the tri-tool conformance harness stops swallowing its own errors
(closes #289). Assertion 8 polled drydock's unversioned /api/containers and
/api/triggers/docker/update, which 410 as of drydock v1.6.0. The 410 body fed
straight into jq, the type error went to 2>/dev/null, and what came back was an
empty result indistinguishable from a real store-sync failure -- which is how a
harness bug got reported as a drydock regression and sat for a month. Nothing
was ever wrong with drydock. Both URLs move to /api/v1; the poll checks the HTTP
status and the {data: [...]} envelope before trusting anything; and both
accepted trigger refusals are now identified by their response body rather than
a bare status, since a wrong URL also answers 404. 501 leaves the accepting arm:
no row has ever returned it.

#296 -- the lockfile-dedupe pre-push hook stops misnaming a stale node_modules
as lockfile drift (closes #295). It probes npm install --dry-run first and names
npm ci, and only then does the dedupe report get to mean anything. Logic moved
into scripts/lockfile-dedupe.mjs with tests.

Verified on conformance run 32323886778: all three rows and the harness
self-test green, with drydock's actual refusal strings recorded in the
artifacts.
