Draft, opened to run CI — in particular the integration job, which boots Zammad and drives it with this gem.

What this is

A breaking 2.0 release. Six commits, each of which builds on its own:

Commit
build: Ruby floor 3.4, refresh dev dependencies
refactor!: rewrite the client internals
feat: RBS signatures + Steep
ci: Ruby matrix, trusted publishing
docs: 2.0 docs and migration table
feat: pattern matching, derived clients
ci: harden the live-Zammad integration job

See the migration table for everything that needs an edit in calling code.

Bugs fixed

  • Collection#each included Enumerable but fetched a single page, so iterating client.x.all silently stopped at 100 records.
  • perform_on_behalf_of used tap with no ensure, so an exception in the block left the From header set on every later request.
  • The transport logged user:password on every client build, and logged request payloads verbatim including passwords sent when creating users.
  • No timeouts at all; no retries; Faraday exceptions leaked to callers.
  • Absolute request paths stripped the prefix from Zammad installations served from a sub-path.
  • safe_json_parse returned {} for an unparseable body, which callers then iterated as key/value pairs.
  • The integration suite only ran Zammad's auto wizard because authentication_spec.rb happened to sort first.

Verified locally

308 unit specs (no Zammad needed), RuboCop clean with the .rubocop_todo.yml backlog resolved rather than carried, Steep clean, 99.6% line coverage, gem builds.

What this PR is meant to verify

The parts I could not check locally:

  • that the Zammad boot sequence still works,
  • that real Zammad payloads match what the gem expects (my local check ran against a stub I wrote, so ParseErrors here are the thing to watch),
  • that zammad/zammad-ci:latest ships Ruby >= 3.4, now that the gem requires it. The Report the toolchain step fails early and explicitly if not.

Note before tagging a release

release.yml publishes via RubyGems trusted publishing. That needs a one-time trusted publisher configured on rubygems.org and a rubygems environment in this repo, otherwise tagging v2.0.0 will fail at the publish step.

Ruby 3.0 has been end of life since April 2024, and 3.1 through 3.3 are
either past or close to their own end of life. Zammad itself pins 3.4.9,
so a 3.4 floor matches the primary audience and lets the code use `it`
and Data without compatibility branches.

Also:
- add faraday-retry, needed for the retrying transport that follows
- add rbs, steep, simplecov and yard for the tooling that follows
- drop the $LOAD_PATH hack from the gemspec in favour of require_relative
- track .ruby-version instead of ignoring a file that was committed anyway
- add bin/setup and bin/console
- raise TargetRubyVersion to match, which needs UseAnonymousForwarding and
  BlockForwarding set explicitly to keep named parameters

The 1.x internals had several defects that could not be fixed without
breaking the public API:

- Collection#each included Enumerable but fetched a single page, so
  iterating `client.x.all` silently stopped at 100 records.
- perform_on_behalf_of used `tap` with no `ensure`, so an exception in
  the block left the From header set on every subsequent request, and
  the mutable setter was unsafe to share between threads.
- The transport logged "user:password" on every client build, and logged
  request payloads verbatim, including passwords sent when creating users.
- Requests had no timeouts, so a hung server blocked indefinitely, and no
  retries, so a transient 502 surfaced to the caller.
- Faraday's ConnectionFailed and TimeoutError leaked to callers.
- Resource paths were absolute, which stripped the prefix from Zammad
  installations served from a sub-path such as /zammad/.
- safe_json_parse returned {} for an unparseable body, which callers then
  iterated as key/value pairs.
- method_missing was used without respond_to_missing?, and resources were
  resolved with const_get on user input.

What replaces them:

- Config: an immutable, validated value object whose inspect redacts
  credentials, so it is safe to log or attach to an error report.
- Transport: timeouts, retry with exponential backoff for idempotent
  requests only (POST is never retried, so a failed create cannot
  duplicate a record), and Faraday errors wrapped as ConnectionError or
  TimeoutError. Credentials and sensitive payload keys are redacted.
- Response: a decoded response object, so Faraday is no longer part of
  the public surface.
- One error class per status: AuthenticationError, AuthorizationError,
  NotFoundError, ValidationError and RateLimitError (with #retry_after).
- Collection: lazily and automatically paginated, with each_page, where
  and immutable page. Replaces ListBase, ListAll and ListSearch.
- ResourceProxy: explicit find/all/search/create/new/destroy instead of
  method_missing plus const_get. Resource readers on Client are defined
  explicitly, so respond_to? answers correctly.
- AttributeAccess: shared attribute reads with respond_to_missing?, a
  strict #fetch, and symbolization that also descends into arrays.

Specs are split so that `rake spec:unit` runs 287 examples against
stubs with no Zammad instance; the specs that need a live server moved
to spec/integration. The .rubocop_todo.yml backlog is resolved rather
than carried: every suppression that remains is an explicit decision in
.rubocop.yml with a reason.

BREAKING CHANGE: see the migration table in the README.

Hand-written signatures for the whole public API, verified by
`rake steep`. Typed projects get checking and editor completion, and the
signatures are published with the gem.

Two things worth knowing about the setup:

- sig/vendor/faraday.rbs stands in for Faraday, which ships no
  signatures. It is excluded from the built gem, because publishing
  third-party signatures would conflict with a consumer's own.
- RBS cannot describe the initializer that Data.define generates, so the
  super call in Config carries a scoped steep:ignore block rather than
  thirteen individual ignores.

Record attributes stay untyped on purpose: Zammad allows
administrator-defined custom fields, so the attribute layer is checked
for structure, not for field names.

…shing

- Split the unit specs, which need no Zammad, from the integration
  specs, so most breakage is caught in seconds rather than after a full
  Zammad boot.
- Run the unit specs on Ruby 3.4, 3.5 and head; head is allowed to fail.
- Add RuboCop and Steep jobs.
- Restrict the default GITHUB_TOKEN to contents:read and cancel
  superseded pull request runs.
- Publish from a tag through RubyGems trusted publishing (OIDC), so no
  API key needs to live in this repository. This needs a one-time
  trusted publisher configured on rubygems.org and a `rubygems`
  environment in the repository settings before a tag will publish.
- Group Dependabot updates so development churn is one pull request.
- Run RuboCop and the unit specs as pre-commit hooks.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The README now covers the client options, the error hierarchy, lazy
collections, logging and the type signatures, and carries a migration
table listing every change that needs an edit in calling code, with the
reason for each.

Most calling code is unaffected: find, all, search, create, new, save,
destroy, changes, attribute readers and writers, ticket.articles,
ticket.article and attachment.download are unchanged.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Modern Ruby features applied where they pay for themselves:

- Records implement deconstruct_keys, so Zammad objects can be used with
  case/in, including against nested attributes. Config and Response are
  Data objects and already matched on their members.
- Client#with derives a new client with changed options. It goes through
  Data#with, which re-runs Config's initialize, so the derived options
  are validated rather than trusted, and any on_behalf_of scope carries
  over.
- Response#decoded checks a body against the expected :object or :array
  shape with a single pattern match, replacing four hand-rolled is_a?
  guards that each produced a slightly different message. Error message
  formatting now lives in one place, Error.subject_for.
- Endless method definitions for the 24 genuine one-liners.

Also adds specs proving a shared client does not leak an on_behalf_of
scope across threads, which is the point of making the transport
immutable rather than a documented hope.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The integration job existed but had latent problems that would only show up
as confusing failures:

- `source .gitlab/environment.env` ran in one step's shell, so Zammad's
  generated CI environment was gone by the time the specs ran, and TEST_URL
  was never derived from the port Zammad actually listened on.
- Nothing waited for Zammad to accept connections, so the suite could start
  against a server that was not up yet.
- No timeout, so a hung boot would hold a runner for the six hour default.
- The Zammad ref was implicit (whatever `develop` happened to be) and there
  was no way to run the job against a specific ref.
- A failed boot produced a bare connection error with no logs.

Now the job reports the toolchain (failing early and clearly if the
zammad-ci image ever ships a Ruby older than this gem requires), boots
Zammad at a pinned ref, promotes its environment into $GITHUB_ENV, polls
until the instance answers, runs script/check_connection.rb as a preflight,
runs the integration specs, and uploads Zammad's logs on failure. It is
gated behind the unit job so a broken unit suite does not pay for a Zammad
boot, and is triggerable by hand with a chosen Zammad ref.

script/check_connection.rb drives a live instance through the documented
workflows in one linear pass and prints a transcript. It stops at the first
failed precondition, so an unreachable or unconfigured instance yields one
clear line instead of a cascade of NoMethodErrors on nil.

Integration setup no longer depends on spec file ordering: the auto wizard
runs from a hook, once per suite, and an instance that is already set up is
no longer treated as an error.

📝 Walkthrough

Walkthrough

The release updates the gem to version 2.0.0 and Ruby 3.4+. The client now uses immutable configuration, structured transport responses, typed errors, resource proxies, namespaced resources, and lazy collections. RBS signatures, unit tests, integration checks, examples, documentation, CI workflows, and trusted publishing automation were added or updated. Legacy dispatcher, list, logging, and JSON helper components were removed.

Merge Risk: 🟡 Moderate · up to 204b7

The client and transport rewrite changes request handling, retries, logging, parsing, and resource behavior, but the current head still has concrete security and correctness risks: credentials may remain exposed in logs or configuration output, attachment examples may overwrite or write outside their intended directory, and malformed responses or repeated attribute assignments can behave incorrectly. These issues should be fixed or explicitly accepted before merging.

Both found by actually running the workflow.

The Boot Zammad step aborted immediately with

    /etc/profile.d/rvm.sh: line 29: rvm_path: unbound variable

because I had added `set -euo pipefail`. RVM's profile script reads unset
variables, so nounset kills it; the upstream script worked precisely
because it did not set -u. Keeping -e and pipefail, dropping -u.

The Ruby head job could not install at all:

    ffi-1.17.4 requires ruby version < 4.1.dev, which is incompatible with
    the current version, 4.1.0.dev

ffi arrives via steep -> listen -> rb-inotify, and Ruby head is now
4.1.0.dev. The unit specs do not need the type-checking toolchain, so the
unit job installs with BUNDLE_WITHOUT=development. The types job keeps
installing it on a released Ruby. This also speeds up the matrix.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
All 53 integration specs failed against a real Zammad with

    Zammad ... is not set up and the auto wizard did not run:
    {"error" => "Authentication required"}

The preflight step runs Zammad's auto wizard, so by the time the specs ran
the wizard reported failure and the fallback check took over. That fallback
read GET /api/v1/getting_started expecting {"setup_done": true}, but a
configured Zammad requires authentication for that endpoint, so the check
could never succeed on an instance that was already set up.

Replaced with an authenticated request, which answers the only question
that actually matters: can the suite talk to this instance as the
configured user. Same fix in script/check_connection.rb, which had the same
flawed fallback and only avoided it by happening to run the wizard first.

This also affected anyone re-running the integration suite twice against
the same instance.

Also asks setup-ruby for the latest bundler on Ruby head: the 2.6.9 pinned
by Gemfile.lock crashes there with NameError on the removed
Pathname::SEPARATOR_PAT.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Ruby head cannot install this gem's development dependencies at all, for
two reasons that both sit outside this repository:

- With Gemfile.lock present, bundler honours `BUNDLED WITH 2.6.9`,
  self-downgrades from head's own 4.1.0.dev, and then dies with
  `NameError: uninitialized constant Pathname::SEPARATOR_PAT`, which head
  removed. Asking setup-ruby for a newer bundler does not help, because the
  lockfile pin wins.
- Without the lockfile, a fresh resolution pulls
  steep -> listen -> rb-inotify -> ffi, and ffi requires Ruby < 4.1.dev.

Neither says anything about whether this gem works on head, and a check
that is permanently red teaches people to ignore CI. The matrix keeps 3.4
and 3.5, both green. The reason and the route back are recorded in the
workflow so head can be restored when either issue is fixed upstream.

@mantas for the general approach, I'd suggest a beta/rc phase like for the php client, to give people a chance to provide feedback.

`ruby-version: '3.5'` did not test Ruby 3.5. No stable 3.5 exists yet, so
setup-ruby resolved it to the newest 3.5 build available, 3.5.0-preview1
from 2025-04-18 — a preview that predates 3.4.9 and is not something to
gate merges on. My earlier check of ruby-lang.org appeared to confirm a
3.5.0 release only because the regex I used dropped the `-preview1`
suffix.

The newest stable Ruby is 3.4.10, so with required_ruby_version >= 3.4 the
matrix is the 3.4 line alone. Kept as a matrix, with the reasoning
recorded, so adding '3.5' on release is a one-word change.

Yep. This is definitely too big to drop on the spot.

mantas and others added 5 commits August 27, 2026 17:20
Ruby 4.0 is the current stable line (4.0.6 at time of writing). I had
missed it twice, because the regex I used to check ruby-lang.org hardcoded
`Ruby 3\.` and so could only ever report 3.x — which also explains the
earlier claim that 3.4.10 was the newest stable.

There is no 3.5 to add: that line was abandoned after 3.5.0-preview1 and
became 4.0. head remains excluded, and the ffi constraint that blocks it
(Ruby < 4.1.dev) is satisfied by 4.0, so 4.0 installs the full toolchain
normally.

Left spec.email as the shared support@zammad.org address rather than
adding a personal one, since the gemspec is published publicly.

Six scripts covering what a real project actually does with this gem:

- ticket_report.rb      bulk CSV export; automatic pagination, each_page
                        batching, client.with for a long-running job
- triage_tickets.rb     search, lazy early exit, case/in pattern matching on
                        records, staged changes, adding an article
- onboard_customer.rb   organization + user + a ticket raised on behalf of
                        that user, both scoped-client and block forms
- download_attachments  walking articles, binary-safe attachment downloads
- error_handling.rb     every error class, retry_after, server_message, and
                        configuration rejected before any request is made
- concurrent_sync.rb    a worker pool sharing one immutable client, plus the
                        Rails initializer shape in a comment

All six were run against a stub Zammad and produce the expected output,
including both branches of the pattern match in triage_tickets.rb.

examples/ is no longer excluded from RuboCop. An example that no longer
compiles is worse than no example, and the exclusion is what let the old one
drift.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Pagination was used across the other examples but never explained, and
page, where and [] were not demonstrated anywhere — a gap worth closing,
since pagination is the biggest behavioural change from 1.x.

examples/pagination.rb walks a collection every available way and prints
what each one actually costs in HTTP requests, measured by counting the
requests the client logs through an injected Logger. That makes the lazy
behaviour concrete: building a collection is 0 requests, `.first` is 1
however long the list, `.first(7)` at 5 per page is 2, and a full traversal
is one request per page plus one to discover the end.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`each` and `each_page` own the loop, which is wrong for a job that has to
checkpoint, throttle, or hand batches to a queue. examples/manual_batches.rb
shows the four approaches and when each fits:

- `each_page` without a block returns an Enumerator, so `next` pulls exactly
  one page when the consumer is ready and the rest is never fetched
- `each.each_slice(n)` decouples processing batch size from API page size
  (fetch 5 per request, commit 12 at a time)
- an explicit `page(n, per_page:)` loop that persists the page number, so an
  interrupted run resumes; it checkpoints after the batch is handled, so a
  crash repeats a batch rather than skipping one
- the same loop throttled, with RateLimitError#retry_after honoured

Verified against a stub, including that seeding the cursor at page 4 really
does resume there and process only the remaining pages.

- Around line 27-35: Update the attachment path construction in the nested
article/attachment iteration to include an attachment ordinal or other stable
unique value alongside the article ID and filename, ensuring same-named
attachments cannot overwrite one another and saved accurately reflects written
files.

In `@examples/example_http_token.rb`:
- Around line 56-59: Update the attachment-writing loop after
ticket.articles.first&.attachments&.each to write only into a dedicated download
directory, validate or derive each filename with its basename so absolute paths
and traversal segments cannot escape that directory, and pass the resulting
controlled path to File.binwrite.

In `@examples/manual_batches.rb`:
- Around line 108-115: Update the request block around client.ticket.all in the
batch flow to track rate-limit retry attempts, retry only up to a defined
maximum, and re-raise the ZammadAPI::RateLimitError once that limit is exceeded;
preserve the existing retry-after wait behavior for allowed attempts.

In `@examples/ticket_report.rb`:
- Around line 37-45: Update the CSV row construction in the ticket report to
neutralize spreadsheet formula prefixes for every ticket-derived cell before
export, including values beginning with =, +, -, @, tab, or carriage return;
preserve the required ticket ID lookup and existing column order, and add a
regression case covering a title beginning with =1+1.

In `@lib/zammad_api/config.rb`:
- Line 72: Update Config#inspect to redact credentials in the proxy URL,
including username and password, before rendering it. Reuse the existing
REDACTED_ATTRIBUTES policy where appropriate and preserve safe output for other
configuration attributes.
- Around line 98-110: Update the Config initialization for stored string values
so each caller-provided string is duplicated and frozen before being retained,
including URL, credentials, proxy, user agent, and other string-valued settings.
Preserve non-string values and existing normalization/presence behavior, and
ensure Config’s exposed members cannot be mutated through methods such as
Config#url.

In `@lib/zammad_api/resources/base.rb`:
- Around line 122-125: Update write_attribute so changes preserves each
attribute’s original baseline instead of overwriting it on subsequent
assignments. When the new value equals that baseline, remove the attribute from
changes; otherwise retain the existing baseline and current value so changed?
and save avoid no-op updates.
- Line 99: Update reload where it assigns response.body to `@attributes` to use
response.decoded with the object type, operation "reload object", and self.class
as resource_class. Preserve the decoded-object validation so non-JSON,
malformed, or array responses raise ParseError before replacing `@attributes`.

In `@lib/zammad_api/transport.rb`:
- Around line 196-202: Update redact so hash keys are considered sensitive when
they contain or end with a configured sensitive-key token, rather than requiring
exact equality. Ensure password_confirm, access_token, and refresh_token are
redacted while preserving recursive handling for other hashes and arrays.
Centralize the matching logic in a sensitive_key? helper and update
SENSITIVE_KEYS declarations consistently.

In `@README.md`:
- Line 249: Update the fenced code block beginning at the affected README
section to include the text language identifier, changing the opening fence to
```text while preserving the block’s contents and closing fence.

In `@spec/support/integration_helper.rb`:
- Around line 59-61: Update the self.connection method to configure finite
open_timeout and timeout values in the Faraday connection options, preventing
setup requests from hanging when the configured TEST_URL accepts connections
without responding.

In `@spec/unit/zammad_api/client_spec.rb`:
- Around line 228-238: Update the “leaves the shared client unscoped throughout”
example to assert the shared client’s request does not include a From header
after the threaded on_behalf_of calls. Configure the request stub to reject or
verify that header is absent, and replace the client.config frozen assertion
with this request-based check.

In `@spec/unit/zammad_api/transport_spec.rb`:
- Around line 284-290: Update the “stays silent by default” example to observe
the logger or output stream actually used by unit_transport, wiring quiet into
the transport’s logger configuration or asserting the default logger destination
directly, so the request’s default logging behavior is genuinely verified.

Transport#decode_body hands back the raw String for a non-JSON content
type, an empty body, or a JSON::ParserError, so Response#body is not
guaranteed to be a Hash. Every other call site guards against that with
Response#decoded; reload was the only place in lib/ that assigned
Response#body straight to @attributes, and it accepted a JSON array
just as happily.

The result was that a proxy answering with an HTML gateway-timeout
page — the shape of issue #29 — left @attributes holding a String,
and the next attribute read failed with `TypeError: no implicit
conversion of Symbol into Integer` instead of the ParseError that
Response#decoded exists to raise.

reload now goes through decoded(:object) like save does. Because
decoded raises before the assignment, a failed reload also leaves the
record's existing attributes intact rather than half-replacing them.

Covered by three specs — an array body, a text/html body, and the
record keeping its attributes after a failed reload. All three fail
against the previous code.

Reported by CodeRabbit on #53.

Config promises that a config object is safe to log, and the transport
promises the same for its debug output. Both leaked.

Config#inspect rendered proxy verbatim, and a proxy URL carries its
credentials inline, so `http://user:pass@proxy:8080` printed the
password in full. The userinfo is now blanked while the host stays
visible, which is the part worth seeing in a bug report.

Transport#redact matched payload keys against an exact list, so the
keys Zammad and OAuth actually send went straight to the log in clear
text: password_confirm (Zammad's own object attribute), access_token,
refresh_token and client_secret. Matching a substring instead covers
those and every key the old list held.

Config also stored caller-supplied strings as-is. Data members are
mutable in Ruby, so `config.url << "..."` worked and mutated the
caller's own string object at the same time, and any Transport built
from that config afterwards would pick up the change. Each string
member is now a frozen copy — copied rather than interned with
String#-@, so a credential does not outlive its config in the global
fstring table.

write_attribute recorded the current attribute value as the "old" half
of the change every time it ran, so the baseline moved with each
assignment. Writing an attribute twice reported the intermediate value
rather than the one the record was loaded with:

    group.name = 'First'
    group.name = 'Second'
    group.changes  # => {name: ["First", "Second"]}

and setting a value back to what it started as left the record dirty,
so save issued a no-op update for it.

The baseline is now the value already recorded for that attribute, or
the loaded value on the first write, and a write that restores the
original drops the change entirely.

"leaves the shared client unscoped throughout" asserted only that
client.config is frozen, which stays true whether or not on_behalf_of
leaked a scope onto the shared client. It now makes a request from the
shared client after the threads finish and asserts that request carried
no From header — the thing the name claims.

"stays silent by default" built a StringIO, stubbed :write on it and
never passed it to the transport, so the expectation held no matter
what the default logger did. It now asserts that a request through a
default transport writes nothing to stdout or stderr. The surrounding
let(:output) had to be renamed, because it shadowed RSpec's own output
matcher.

Both were confirmed to fail against the behaviour they describe before
being kept.

The integration helper's bare Faraday connection also had no timeouts,
so a TEST_URL that accepts a connection and then never answers would
hang the integration job rather than failing the setup check.

The examples are meant to be copied into real projects, so the ones
handling server-supplied data should model the safe version.

ticket_report.rb wrote ticket fields straight into CSV. A title is
whatever the customer typed, and a spreadsheet evaluates a cell
starting with =, +, -, @, tab or CR as a formula, so an exported
report could execute a customer-controlled formula on open. Every
ticket-derived cell is now forced to text.

download_attachments.rb and example_http_token.rb built a path from
attachment.filename, which the server supplies. A name containing
../ escaped the download directory, and example_http_token.rb wrote
into the working directory besides. Both take File.basename and a
dedicated directory now; download_attachments.rb also includes the
attachment id, so two same-named attachments on one article no longer
overwrite each other and inflate the saved count.

manual_batches.rb retried a rate-limited page forever. It now gives up
after five attempts rather than sleeping in a loop with no way out.

Also adds the missing language to a README code fence (MD040).

`all` and `search` took pagination and filters in one keyword bag, so
the page size had to be repeated at every entry point — `all(per_page:)`,
`search(per_page:)`, `page(n, per_page:)` — and a `page:` inside that bag
was accepted and then silently dropped. Collections now build up by
chaining, in vocabulary Ruby users already know:

  client.ticket.where(state: 'open').per(500)
  client.ticket.all.in_batches(of: 500) { |tickets| import(tickets) }
  client.ticket.all.find_each(batch_size: 500) { |ticket| archive(ticket) }
  client.ticket.all.page(2).per(50)
  client.ticket.search('crash').first(10)

`page(n)` plus `per(n)` replace `page(n, per_page: m)`, `in_batches`
replaces `each_page`, `where` is also available on the proxy, and the
search term is positional. `Collection#[]`, `#per_page` and
`#current_page` are gone.

Separating the two concerns closes three defects the old shape allowed.

`per` clamps to the page size the endpoint actually serves, so asking
for more no longer truncates the result set. Zammad caps per_page per
endpoint (100 for /api/v1/tickets, 200 for a search, 1000 for the other
index endpoints) and derives the offset from the capped limit, so
`all(per_page: 250)` fetched page one and stopped: 100 records looked
like a short final page. All 250 are walked now.

`where` raises ArgumentError for `page`, `per_page`, `expand` and
`only_total_count` instead of accepting them and overriding them when
building the request.

`#[]` is removed. It cost a request per index and ignored the page a
collection was limited to, so `all.page(4)[0]` returned the first record
of the whole list rather than of page 4.

Two additions come out of the same work. `count` asks a search endpoint
for its total in one request (`only_total_count=true`) rather than
walking every page, and `PaginationError` is raised when an endpoint
answers a page with the page before it, so a proxy that strips the query
string fails instead of paging forever. Every endpoint this client uses
honours `page` today.

2.0.0 is unreleased, so there are no deprecation shims; `all` and
`search` leave the README's "unchanged from 1.x" list.

The YARD tags still described `#response` as a `Faraday::Response`, which
2.0 replaced with `ZammadAPI::Response` so that Faraday stays an
implementation detail of the transport. The README and the changelog both
document the new type; only these two tags were left behind.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The resource classes cover seven Zammad objects. Everything else -
roles, tags, overviews, macros, webhooks, time accountings - had no
route through this gem at all, because Transport is private API. The
only way out was to build a Faraday connection by hand and reimplement
authentication, retries, credential redaction, JSON decoding and the
error mapping alongside it.

These four methods hand back the same ZammadAPI::Response the resource
classes work with, so the status and headers stay reachable, and a
non-2xx response raises the same error class it would for a modelled
resource. POST stays unretried.

Paths are relative to the instance URL so a sub-path install keeps
working, and a leading slash is stripped so paths can be pasted
straight from the Zammad documentation.

`save` raising on a rejected attribute forced a begin/rescue around
every edit, which is not what anyone reaching for `save` expects. It now
returns whether the record was stored and leaves the rejection in
`#error`, so a form-shaped flow reads as a conditional.

Only HTTP 422 is caught. An expired token, a missing record or an
unreachable instance still raises, because no correction to the
attributes would change the outcome and swallowing those turns a
misconfigured client into a silent no-op.

`save!` keeps the old behaviour for scripts that should stop on the
first failure, and `create` uses it, so the one-line create still raises
rather than handing back a record that looks created but is not.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`attributes` and `changes` were attr_readers over the live internal
hashes, so `record.attributes[:name] = 'x'` changed what the record
reported while staging nothing - `changed?` stayed false and the next
`save` never sent it. `record.changes.clear` was worse: the attributes
still looked edited but the update went out empty. `to_h` dup'd only the
top level, so a nested hash stayed shared with the record.

Both readers are now deeply frozen, so those writes raise instead of
corrupting the record, and `to_h` hands back a deep copy. `@attributes`
becomes copy-on-write, which is also what makes a persisted record safe
to read from several threads.

Values a caller assigns are copied before being frozen, so freezing does
not reach back into the caller's own string - the same reasoning
Config#immutable already applies to credentials.

build_connection was closed, so a caller who wanted a
persistent-connection adapter, OpenTelemetry instrumentation or a
response cache had no way in short of reopening the class.

`adapter:` names the Faraday adapter and `middleware:` takes any
callable, which runs last in the stack - after this gem's own middleware
and before the adapter - so it sees a request as the client finished
building it and a response before anything else does.

Faraday stays an implementation detail: a Faraday error raised while
building the connection, an unregistered adapter being the likely one,
comes back out as ConfigurationError from the constructor that caused
it.

The vendored Faraday signatures now say that Faraday.new yields the
connection rather than a builder, which is what a caller's middleware
actually receives.

Applying changes meant one writer call per attribute followed by `save`,
so code that receives attributes as a hash - a webhook payload, a CSV
row, a form - had to loop or call `public_send` per key.

`assign_attributes` stages a hash, `update` stages and saves, `update!`
stages and saves raising. Each routes through the same
`write_attribute`, so change tracking, the original-value baseline and
the frozen attribute contract all behave as they do for a single
writer, and `update` sends only what actually changed.

Looking a record up by anything other than its id meant
`where(...).first`, which fetches a page of 100 records to return one,
and asking whether an id exists meant a `find` inside a rescue.

`find_by` sets the page size to 1, so it costs one request for one
record, and `find_by!` raises NotFoundError when nothing matched. Its
message names the attributes searched but not their values, which keeps
the redaction contract intact. `exists?` wraps the rescue, and still
raises for a 403 - not permitted is not the same as not there.

`pluck` reads attributes off every record. Zammad has no sparse
fieldset, so it shapes the result rather than shrinking the request,
which the documentation says outright.

ResponseError gained a `detail:` for describing a failure with no HTTP
response of its own, so find_by! reads as "no record matched" instead of
the "no response" the computed detail would have produced.

Every example script opened with the same four lines of `ENV.fetch`,
which is the shape of a missing constructor rather than a coincidence.
`from_env` reads ZAMMAD_URL and ZAMMAD_TOKEN - or ZAMMAD_USER and
ZAMMAD_PASSWORD, or ZAMMAD_OAUTH2_TOKEN - and lets any passed-in option
win, so `from_env(timeout: 300)` still reads as one call. All eight
scripts now use it, and it names ZAMMAD_URL in the error when no url
turns up anywhere.

`me` answers which account a token belongs to, the first thing anyone
checks against an unfamiliar instance. It was reachable as
`user.find('me')` only because find interpolates the id into the path,
which is not something a caller should have to notice.

`version` reports the Zammad instance's version, documented against
ZammadAPI::VERSION so the two are not confused.

Following a foreign key meant `client.user.find(ticket.customer_id)`
spelled out at every call site, with the client threaded through to
wherever the record ended up.

`belongs_to` and `has_many` declare the targets, and the readers land on
`record.related` rather than on the record itself. That placement is the
whole design decision: requests expand by default, so `ticket.customer`
is already the customer's login and `ticket.state` is already "open".
Defining `customer` on the record would have replaced a loaded string
with an HTTP request under an unchanged name - examples/ticket_report.rb
reads four of these per row and would have turned into four requests per
ticket. Under `related` the cost is visible and the attribute keeps its
meaning.

belongs_to memoizes, because an id's target does not move under the
caller and a loop would otherwise refetch per record; reload and save
drop the memo along with the attributes it was derived from. has_many
does not memoize, so `related.articles` after `ticket.article(...)`
shows the new article - which also keeps Ticket#articles, now one line
over the declaration, behaving exactly as before.

Targets are named as strings and resolved on use, so resources can point
at each other without a load order between their files.

`client.ticket.all.each` names a step that has no alternative: there is
only one collection a proxy could enumerate. Including Enumerable over
`all` and forwarding the chainable part of the collection surface makes
`.all` optional rather than ceremonial, and `client.ticket.first(5)`
stops after one page exactly as the collection does.

`find` stays a lookup by id, overriding Enumerable#find, because an id
is what a proxy is asked for far more often than a predicate - `detect`
is still the block form, and the documentation says so at both ends.
`count` is forwarded rather than inherited so a search still counts in
one request instead of being walked.

Consumers had nothing: testing a class that takes a client meant
intercepting HTTP with WebMock and hand-writing Zammad's JSON, or
stubbing this gem's own methods and testing the stubs instead of the
code.

`ZammadAPI::Test` stands in for a Zammad. It replaces the transport
rather than the socket, so `zammad.client` is a real Client and a
response travels the same decoding, error mapping and record building as
a real one - a stub with status 404 raises NotFoundError, one with 422
makes `save` return false, and records come back frozen and persisted.
`requests` records what was sent, down to the fact that a save sends
only
the changed attributes.

An unstubbed request raises and lists what is stubbed, because answering
with an empty body would turn a wrong path into a confusing assertion
failure three layers away. Stubbing an endpoint twice describes a
sequence, and a stub's `query` matches a subset so it need not repeat
the
expand, page and per_page parameters the client adds itself.

Client#with_transport is the seam, marked private API. Request names the
verb `verb`, because a Data member called `method` would shadow
Object#method on every recorded request.

Six integration specs asserted that saving an invalid record raises,
which stopped being true for `save` when it started reporting a
validation failure as false. They now call `save!`.

They keep asserting ClientError rather than the narrower false-and-error
contract, because the status Zammad answers an empty record with is not
something these specs should pin down; `save!` raises for any of them.
The unit specs cover the false-and-error path against a stubbed 422.

The migration table gained rows for the three behaviours a 1.x caller
can actually trip over - `save` no longer raising on a rejection, the
frozen attribute hash, and following a foreign key - and the closing
"Unchanged" line no longer claims `save`, `changes` and `attributes` are
untouched, which stopped being true.

The feature list names raw requests and the test kit, since both are
reasons to reach for the gem rather than details inside it.

Records compared by object identity, so the same ticket fetched twice
was two unequal records, and uniq, Set, include? and records as Hash
keys all fell back to identity. Two records of the same kind carrying
the same id are now equal, with #hash agreeing so that the hashed
collections work too.

The class is part of the digest because an id is only unique within one
kind of record: ticket 1 and user 1 are different records.

A record with no id stays equal only to itself, because two unsaved
records are two records waiting to be created however alike their
attributes are. That means a record's first save assigns its id and so
changes its hash, and one used as a Hash key before that save has to be
rehashed after it - the same wart ActiveRecord carries, for the same
reason.

This lands on AttributeAccess rather than Resources::Base so that
TicketArticleAttachment, the other record-shaped class, is covered by
the same implementation.

record.to_json fell through to Object#to_json, which serializes an
object as its to_s, so a record rendered as the string
"#<ZammadAPI::Resources::Ticket:0x000000010f589de0>". Caching, queueing
or logging a fetched record is the obvious next thing after find, and
none of it worked.

to_json now renders the attributes, and as_json returns them as a Hash
for ActiveSupport and any encoder following its convention.

to_json takes one optional positional rather than the customary *args:
RBS types Object#to_json as (?JSON::State?), and Steep rejected
splatting an untyped array into that. The single argument is the real
JSON protocol anyway, and forwarding it keeps a nested record and
JSON.pretty_generate working.

Enumerable supplies none of size, length and empty?, so
client.ticket.all.empty? raised NoMethodError - a surprising hole next
to a Collection#count that goes to some trouble to count cheaply.

size and length alias count, so they keep its costs: one request on a
search endpoint, a walk of every page on any other.

empty? asks for a single record rather than a whole page, except on a
collection limited to one page. There the page size decides which
records the page holds, so narrowing it would ask a different question:
page(2).per(50) is records 51-100, while page(2).per(1) is record 2.

A resource proxy forwards all three, like the other collection
shorthands.

The README gained a "Comparing and serializing" section: which records
count as the same record, why an id-less one is equal only to itself,
and the rehash-after-first-save consequence that follows from it.

The changelog entries go in 2.0.0, which is still unreleased, since
both are changes to how a record has always behaved rather than new
surface a 1.x caller could have been using.

Both sit under Counting, since size and length are count and carry its
costs, and the one thing worth saying about empty? is that it asks for
a single record rather than a page.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`per` was a page size looking for a purpose: it sized whatever read
happened to follow it, and on its own said nothing about what it was
for. The size now belongs to the call that does the reading:

    client.ticket.all.find_each(batch_size: 500) { ... }   # walking
    client.ticket.all.in_batches(of: 500) { ... }          # batching
    client.ticket.all.page(2, of: 500)                     # one page

`page` takes the size as `of:`, so `page(2, of: 50)` is records 51 to
100. The two numbers that decide which records a page holds now travel
together rather than being spread across two calls.

Everything else - `each`, `first`, `lazy`, `count` - fetches 100 per
request. Where a sized read is wanted, `find_each(batch_size: n)`
without a block is an Enumerator that walks at that size, so
`find_each(batch_size: 5).first(7)` replaces `per(5).first(7)`.

The unit specs lost the sized collection they leaned on, so walks that
need a small page now go through `find_each`/`in_batches`, and the ones
about walking past a full page use a page of the default size.

The examples follow: `manual_batches.rb` numbers whole responses with
Ruby's `with_index` instead of slicing the record enumerator, and
`pagination.rb` measures the same walks through `find_each` and
`page(n, of: m)`.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Much of each script was policy the client now applies by itself.
error_handling hand-rolled a retry loop over RateLimitError and the
transport errors, manual_batches had a fourth section that slept
between pages, ticket_report derived a longer-timeout client because
"a bulk export runs for a while", and concurrent_sync sorted its
results into a :retry bucket. All of it restates the defaults at the
call site, so the examples were teaching callers to write what they
already have.

What is left is what only the caller can decide: a missing record, a
rejected attribute, bad credentials. error_handling opens by saying
which failures never reach you, then shows `save` returning false with
`record.error` beside `save!` raising, and closes with `client.with`
as the way to change a default rather than to loop around it.

example_http_token.rb becomes quickstart.rb: the old name described
the authentication rather than the script, and it was the one example
that opened with a literal url and token instead of `from_env`. It now
also shows `me` and `version`, and that `save` sends only the staged
changes.

pagination.rb loses the Logger subclass that counted requests to print
a cost per line. The measurement had become the largest thing in the
file, and the numbers it printed needed a paragraph about short pages
before they made sense.

onboard_customer.rb asks `find_by(name:)` for the lookup it was doing
with `search(...).find { ... }`, which cost a page to find one record.

2.0 renames or reshapes most of the surface a 1.x caller touches, and
every one of those decisions is still open until the release. The people
who can say whether a name reads right, or which call the migration
guide fails to cover, are the ones with 1.x code in front of them - and
nothing in the README told them their notes were wanted.

A callout at the top of the README asks for them, and names the four
things most useful to hear: calls the migration guide misses, endpoints
reached through raw requests that should be modelled, gaps in the test
kit, and defaults that always need overriding.

`logger:` was a boolean flag in 1.x - `logger: true` meant debug output
to $stderr - and it takes a Logger in 2.0. Carrying the old spelling
over got as far as the first request, where the transport called
`debug` on `true` and raised NoMethodError from inside the middleware,
which says nothing about the option that caused it.

Config now checks the option along with the rest, so it raises
ConfigurationError before a connection is built. The check is
`respond_to?(:debug)` rather than an ancestry test, because the point
of taking an object is that anything log-shaped works: a Rails logger,
a broadcast, a test double.

One table of twenty rows treated every change alike, which buried the
three that a 1.x caller can trip over without anything raising. Those
lead now, before any table: `record.attributes = {...}` stages an
attribute called `attributes` and saves it to Zammad rather than
assigning anything, `record.new_instance` and `record.url` read as
unknown attributes and answer nil rather than raising, so `if
record.new_instance` always takes the else branch, and a
`rescue Faraday::ConnectionFailed` no longer matches anything.

The rest is split by what a reader is holding: the client, collections,
records, errors, removed constants. Rows the audit turned up along the
way: keyword arguments on Client.new, an unknown option now raising,
`logger: true`, resources being a fixed list rather than a const_get, a
search paged with `page`/`per_page`, and the timeouts and retries 1.x
had none of.

The changelog gains the same entries, and says what 1.x actually did
where the old wording let it pass: `all` accepted `per_page` and the
filters and then discarded both, so the page size was always 100 and
the filters never reached the request, while `search` did honour them.

Review pass over the 2.0 branch. All 559 unit specs, RuboCop and Steep pass, and the integration job is green (53 examples against a live Zammad) — the findings below are things none of those catch. Each was verified by running the code.

7 correctness bugs

collection.rb:207 pagination guard false-positives on records without an id
collection.rb:247 total_count raises ParseError when a search endpoint ignores only_total_count
transport.rb:167 nil query values are silently dropped, turning a null-field filter into no filter
test.rb:133 recorded queries have a shape the real transport never sends
base.rb:216 @error isn't cleared, so a failed save can report the previous failure's cause
attribute_access.rb:138 respond_to? claims a writer that read-only records don't have
base.rb:276 a destroyed record still reports itself as persisted

4 cleanup items

response.rb:29 json? derived from object identity — currently correct by accident
base.rb:264 reset block byte-identical to the one in save!
test.rb:70 rebuilds the whole Faraday stack per call, then discards it
script/check_connection.rb:210 three round trips for one assertion

Two further findings are held back from this review and tracked separately: credentials embedded in url leak into Config#inspect and every error message (same defect class 48e3a8e fixed for proxy), and Client#with hard-codes Transport.new, so a client built through with_transport escapes to live HTTP — which breaks the #with pattern recommended in README.md:505 and examples/error_handling.rb:73 under the shipped test kit.

Separately, the 13 CodeRabbit comments on this PR are all stale — 48e3a8e and dedfdd2 resolved the substantive ones and one is on a since-deleted file. Worth dismissing so they don't read as outstanding.

`filter_map(&:id)` answers `[]` for a page of records that carry no id,
so page 2 compared equal to page 1 and the walk raised PaginationError
after having already yielded both pages. Compare the whole payloads
instead, which is what the guard is actually asking about.

`total_count` had the neighbouring problem: `ResourceProxy#search` marks
every search countable, but an endpoint that ignores `only_total_count`
answers with its usual array and decoding that as an object raised
ParseError instead of falling back to the walk.

`where(owner_id: nil)` reads as "unassigned tickets". The key never
reached the wire, so the request was an unfiltered index and the caller
iterated every ticket believing they were all unassigned - a wrong
result with no error and no log line, undiscoverable short of a packet
capture.

No query string means "this field is null", so there is nothing to send
instead. Say so, and say it before the request is logged.

`answer` stringified only the keys, so a recorded query held raw Ruby
values and kept nils, where `Transport#stringify_query` stringifies
every value and now rejects nils outright. An assertion on `per_page`
failed against the kit and passed against reality; one on a nil-valued
key did the reverse.

`Request#query` is documented as "as the client sent them", so run it
through the transport's own stringification and let that stay true.

`save!` and `reload` each reset the same five fields, byte for byte.
`@related` was added to both in one pass, which is exactly the shape of
the problem: the next per-load field gets added to one and missed in the
other, and a reloaded record keeps an association proxy from before the
reload with nothing to catch it.

`@error` was reset on the success path and in `save`'s rescue, but not
when `save!` raised anything other than a ValidationError. A caller
rescuing a ConnectionError and reading `record.error` to report why the
save failed was told "Name is required" - the cause of the save before
it.

`destroy` returned true without touching the record, so `new_record?`
stayed false and nothing distinguished a deleted record from a live one.
Assigning and saving afterwards sent a PUT to the deleted id, and the
mistake surfaced one call later as a 404.

A record now reports `destroyed?`, `persisted?` answers false for one,
and `save` refuses with the reason rather than asking Zammad about a
record that is gone.

`respond_to_missing?` answered true for any name ending in `=`, but
`write_attribute` raises NoMethodError on a read-only record, so
`attachment.respond_to?(:filename=)` disagreed with what calling it did.
That defeats the point of asking, and leads generic code - serializers,
form binders, assign_attributes loops - straight into the exception it
was checking to avoid.

`json?` was derived from `body` and `raw_body` being the same object,
which held only while every producer was careful to hand the same String
to both - and the test kit did it deliberately, with a comment
explaining the trick. Any edit that duped, re-encoded or normalised the
raw body would have flipped it to true with nothing to catch it.

`decode_body` knows the answer, so it says so and `Response` carries it.

Every `zammad.client` ran `Config.new` with its four validators and
assembled a whole Faraday stack - auth, JSON and retry middleware,
adapter resolution - that `with_transport` then threw away. For an
object that never opens a socket, a suite reaching for it in each
example paid the whole thing every time.

`attachment.download` was called three times for one assertion: once to
compare, once to build the failure message, once for the byte count.
Each is a full attachment fetch, in a job whose point is a fast,
readable transcript of a freshly booted Zammad.
