Deletes the V0 capture implementation and the `capture-v1` Cargo feature. Capture V1 (`POST /i/v1/analytics/events`) is now the only capture path and compiles unconditionally. No V1 logic, retry policy, buffering, or option-extraction behavior changes — the V1 code is byte-identical, it just stops being `#[cfg]`-gated. - Delete `src/client/v0_capture.rs`, the V0 transport pipeline, the V0 retry decisions (`should_retry_v0` and friends), the V0 wire format's `BatchRequest`, and both `send_immediate` V0 bodies. - Drop the `capture-v1` feature; `brotli` and `zstd` become unconditional dependencies. All four codecs the endpoint accepts (gzip/deflate/br/zstd) now work by default instead of silently degrading to uncompressed. - Compliance adapter advertises `capture_v1` unconditionally and reports as `posthog-rs`; delete the V0 adapter image and its workflow. The `capture_v1` capability string is a frozen harness contract key. - Collapse the CI build/test matrices, whose V0 and V1 entries became duplicates, and drop `--features capture-v1` from `check-public-api.sh`. `Event::prepare_for_v0` and `InnerEvent` are retained temporarily as test-only scaffolding; the tests that depend on them are ported to the V1 builder in the next commit, which then deletes them. Verified against a pre-change baseline: 379/316/356 tests pass for the default, blocking, and blocking+error-tracking configs — identical counts to the same suites under `--features capture-v1` before this change. Public API snapshot unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Rewrites the tests that depended on the V0 serialization scaffolding, then deletes that scaffolding, so nothing V0 remains in the tree. - `src/error_tracking.rs`: `built_event_json` now serializes through `V1Event::from_event`, so all 33 tests assert the shape actually sent. Two assertions move `$process_person_profile` from `properties` to the typed `options` object and additionally pin that it is stripped from `properties`. - `src/event.rs`: 10 `v0_*` tests ported to assert the V1 shape and renamed without the version marker. `v0_adds_lib_properties` and `v0_preserves_existing_lib_properties` are dropped instead — the V1 builder never touches `$lib`/`$lib_version`, which now travel in the `posthog-sdk-info` header and are covered by `build_headers_sdk_info_is_canonical_lib_slash_version`. - Delete `Event::prepare_for_v0`, `Event::apply_minimal_flag_called_allowlist`, and `InnerEvent`. The shared `is_minimal_flag_called_property` predicate is kept — the V1 path uses it. `semver` was only used by `prepare_for_v0`, so it is dropped as a dependency. - Port the orphaned integration assertions that had no V1 twin, in both the async and blocking variants: `Event::with_flags` attaching flag properties without a second `/flags` fetch, `$is_server` on `$feature_flag_called`, client-level `ErrorTrackingOptions` applying to `capture_exception`, and the blank/whitespace API-key noop path. Test totals move 379/316/356 -> 381/317/358 for the default, blocking, and blocking+error-tracking configs: four ported tests added per applicable config, less the two `$lib` tests whose behavior moved to the header. Public API snapshot unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The `V1` markers existed only to scope the new pipeline during the dual-use period. With V0 gone they are noise, so this adopts plain capture names — including the pre-existing public `Endpoint::Capture`. Mechanical rename only: no logic, retry, buffering, or option-extraction behavior changes, and no existing test's assertions were altered. Breaking: - `V1ErrorResponse` -> `CaptureErrorResponse`, which also re-signatures the public `CaptureFailure::error_response()`. - `Endpoint::Batch` removed; `Endpoint` is now `#[non_exhaustive]`. - `Endpoint::Capture` re-points from `/i/v0/e/` to `/i/v1/analytics/events`. Callers of `Endpoint::Capture.path()` compile unchanged but see a different URL — the one change here with no compile-time signal. Internal: - `V1Event` -> `CaptureEvent` (not `Event`, which is taken by the public input type), `V1BatchRequest{,Ref}` -> `BatchRequest{,Ref}`, `PreparedV1` -> `Prepared`. - `src/event_v1.rs` -> `src/capture_event.rs`, `src/client/v1_capture.rs` -> `src/client/capture.rs`. The former cannot be `event.rs` — the public `Event` lives there. - `V1_CAPTURE_PATH` is deleted; both call sites now go through `build_url(Endpoint::Capture)`, which is byte-identical output since `build_custom_url` only normalized a leading slash that was already present. - Tests renamed to match: `test_v1_capture.rs` -> `test_capture.rs`, `test_v1_blocking.rs` -> `test_capture_blocking.rs` (not `test_blocking.rs`, which survives), `test_error_tracking_v1.rs` -> `test_error_tracking.rs`. - `compliance/v1/` -> `compliance/harness/`, and the compliance workflow drops its `-v1` suffixes. The harness contract keys are deliberately untouched: the `capture_v1` capability advertised by the adapter and the `--suite capture_v1` argument are external strings the test harness matches on. Adds the major-release changeset. Test counts are unchanged from the previous commit (381/317/358), and the public API diff is exactly the three intended items with nothing else moving.

`compliance/harness/Dockerfile` does `COPY . .` from the repo root, so with no .dockerignore the build context included the whole local `target/` tree — 33GB after a few cargo runs here — and the build died with ResourceExhausted while hardlinking incremental artifacts. CI never hit this because a fresh checkout has no `target/`, which is why the documented local compose path was quietly broken for anyone who had built the crate. Excluding target/, .git/, and .github/ drops the context from 33GB to 1.14MB, which also trims the CI build. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Porting the V0 tests left `event.rs` asserting the capture wire shape, which `capture_event.rs` already owns — six were straight duplicates (timestamp normalization, the anon/group/explicit `$process_person_profile` cases, and `$groups`). Wire-shape assertions now live only in `capture_event.rs`, next to the builder they exercise; `event.rs` keeps just its `Event`-level timestamp tests. The four assertions that were genuinely unique moved across rather than being dropped: `distinct_id` at the root (with no legacy `$distinct_id` and no duplicate in properties), auto-generated and caller-overridden `uuid`, and `$process_person_profile` being absent from *both* options and properties when unset. The `$lib`-coverage note moved with them. Net -6 tests per config (375/311/352) — the duplicates, nothing else. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…h exists The v0/v1 split left scaffolding that no longer earns its keep. - Drop `--suite capture_v1` from the local compose. That filter existed only to pick v0 and v1 apart; with one capture path the harness selects suites from the adapter's advertised /health capabilities, which is what CI already does (it passes no --suite). Local runs were silently narrower than CI as a result — 94 tests instead of 111, skipping feature_flags entirely. - Flatten `compliance/harness/` back to `compliance/`. The extra directory level only existed to hold the two per-mode variants. Verified from the new layout: 111/111, capabilities `capture_v1, encoding_gzip`.

…ption (#279) * feat!: stop forcing person processing for groups; new_anon sets the option * test: pin legacy option properties surviving minimal flag events * feat!: add SDK values before before_send; caller values win $os, $os_version, $is_server and $geoip_disable now go in before the before_send hooks, only for keys the event leaves unset. The hook sees them and can remove them; the wire builder no longer adds them again. Event::with_flags keeps flag properties the event already has, and add_group groups merge into a $groups property key by key. * fix(capture): strip caller-set $lib and $lib_version before send Capture sets both from the PostHog-Sdk-Info header and appends them after the event's keys, so a copy left in properties is a duplicate JSON key. Also corrects two migration guide lines: new_anon differs from every 0.x build, and the default V0 path already added $os before before_send. * docs: note group person processing on exceptions and show insert_option

* fix(capture): drop oversize AI events locally on the immediate path capture_ai_immediate and capture_ai_batch_immediate now apply the 8 MiB per-event limit before sending, like the background AI lane. An event over the limit is not sent and gets a local drop verdict with the detail ai_event_too_big in the returned CaptureSummary. * fix(retry): default to 4 capture attempts from 100 ms and give /flags its own backoff max_capture_attempts now defaults to 4 and retry_initial_backoff_ms to 100. Remote /flags retries use a fixed backoff of 300 ms, doubling up to 30 s, instead of the capture retry options. * test: set explicit uuids in the immediate size-ceiling test The test read each event's uuid before capture; setting it explicitly keeps the test independent of when the SDK assigns uuids.

…lank ids as anonymous (#287) A cloned or reused Event no longer sends one uuid twice: the client assigns the uuid when it takes the event, unless set_uuid was called. set_timestamp no longer rejects future timestamps; PostHog clamps them. Event::new with an empty or whitespace-only distinct id creates an anonymous event. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

A phx_ key passed as the project api_key disables the client with one error log, as an empty key does, so a key PostHog always rejects is never sent. The empty-key message moves to error level, and an explicitly disabled client logs nothing about its key. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

…iB (#288) Capture V1 refuses an analytics body over 10 MiB, and the SDK sends bodies uncompressed by default, so a count-only batch of large events could fail whole. The analytics lane now splits each send by serialized bytes with the check-before-append rule. Events are still built at send time, so before_send timing is unchanged; immediate batches stay one request. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

* fix: add jitter to capture retry waits Each capture retry wait is scaled by a random factor between 0.75 and 1.25, then clamped to retry_max_backoff_ms, so clients that fail together do not retry together.

* fix: report capture's dropped duplicate copies as drops Capture v1 keeps the first event for each uuid in a request and drops later copies, reporting the count as duplicates_dropped on the uuid's result.

) A `$trace_id` or `$span_id` set as an exception property now wins over the trace context provider, and setting either one stops the SDK adding both provider IDs, so an event never mixes IDs from two trace contexts.
