docs(php-sdk): refresh SDK-owned pages against main (556084c..fba2089)
Covers the 79 commits since the last verified watermark, excluding the
287 auto-generated packages/Types/lib/Generated files.
New surface:
- Configuration: debugToken (forced debug_token= + _conv_low_cache=1,
full PSR-16 config-cache bypass, log redaction incl. PSR-18 exception
messages, never sent to the track endpoint); the Comparisons operator
set now that exists/not_exists/doesNotExist landed; the fixed
ConvertAgent/1.0 User-Agent applied after the header merge.
- CodeExamples: Experiment Preview — setPreview(), PreviewParam::parse(),
context-lifetime zero trace, inert-on-bad-input, ?exp= on-demand fetch
memoized 60s under preview_{experienceId}.
- ReturnTypes: SegmentsKeys (visitorType/customSegments rename),
RuleType, ConversionSettingKey, DataStoreQueueReleased.
- Installation: single-package publishing model and the real require set
(PSR interfaces, murmurhash, guzzle/psr7, ext-curl/json/mbstring).
- Testing: cross-SDK parity suite incl. the anchored bucketing golden
vectors (packed version <= 11, anchored version > 11).
- AI_Index/Home: the five shared pages the sync added but nav never got
(qa-and-preview, mutual-exclusion, server-side-experimentation,
from-tracking-script-to-sdk, direct-tracking-endpoint).
Fixes found while verifying against the code:
- LogLevel is int-backed (0-5), not string-backed.
- Core::on() takes a string; SystemEvents::Ready throws a TypeError.
Every event example unwrapped with ->value.
- PSR-18 discovery is Psr18ClientDiscovery::find(), not
HttpClientDiscovery::find().
- SegmentsManager rewritten: dropped the "Chapter 10" framing and six
links to pages deleted in April, replaced excerpts that described an
algorithm the class does not implement, and corrected the
runCustomSegments example to nest rule data under ruleData.
- Documented that Segments/Audiences/DataStoreQueueReleased are never
emitted, and that once one custom segment matches, the rest in the
same call are accepted without evaluating their own rule trees.
