For that purpose, this document takes priority over any other document or code. Not all of the documented intents are realized in the implementation yet. + +When writing a spec or implementing significant changes or tests, check them for consistency with this doc. If not yet consistent, it may be this doc that needs to change, but that change should be reviewed by this doc's owner. + +## Experience principles +- **Offline first.** Show cached content immediately; support reading, composing, and queuing actions regardless of connectivity. Sync in the background without disrupting use. Make unavailable content and prolonged sync problems clear. +- **Responsive UI.** The user interface does not hang or stutter, regardless of the scale of a community or number of communities joined. Expensive or slow operations happen in parallel with UI feedback and animation. Actions are reflected in UI instantly and optimistically. +- **Don't lose user-generated data.** Drafts and pending actions survive restarts, app updates, and cache rebuilds. Important pending actions (e.g. undelivered sent messages) are clearly identified visually and offer affordances for retrying or recovering the uncommitted data. +- **Don't trust relays.** Their behavior is outside our and users' control. Critical actions that the client can enforce, such as leaving a community locally, must not wait for a relay response. Changing a relay-controlled push preference requires relay cooperation: saving a local choice or retrying indefinitely does not guarantee that remote notifications stop. For this setting, show a bounded pending state, then make rejection, unavailability, or missing confirmation clear without claiming success. Warn that notifications may continue and let the user pursue separate recourse; do not queue the failed change for automatic retry. Recourse against a relay that ignores notification preferences is separate from the [mobile push suppression spec](docs/mobile-push-suppression.md). The behavior or performance of one relay that the client is connected to should not degrade the experience of using other relays or non-relay-dependent functionality in the app, including by adding latency. +- **Accessibility.** The app supports platform accessibility features, including screen readers, text scaling, and reduced motion. + +## Relationship to other clients + +Mobile and desktop follow shared rules for behavior such as channel ordering, unread state, and autocomplete. Presentation and interaction should suit each platform. + +The desktop implementation is a reference we can use to inform defining those rules, but it contains bugs and unintended behavior and is not itself the specification. Written intent takes priority over implementation precedent. A clearer vision or spec developed for mobile can establish the intended shared behavior for desktop too. + +## Architecture + +The following are preferred architectural approaches in service of the experience principles. They can evolve when a better approach is established. + +- Verify events on receipt and fold them into the persistent store. Avoid re-verifying events already verified in the current persistent store. UI subscribes to the persistent store, never to events. +- Avoid migrations of the persistent store. It should be fully derived from received events and should be discarded as needed, such as when an app update changes the schema nontrivially. Uncommitted user-generated data that cannot be lost, including drafts and pending actions, should be kept in a separate, minimally scoped persistent store (or multiple). +- Avoid blocking the UI isolate. E.g. with expensive work such as signature verification, JSON or Markdown parsing, writing to the persistent store, or even unbounded text layout. +- Keep background work, storage, and network use bounded, with attention to battery and data consumption. + +## Verification + +- Tests should be fast and deterministic (not flaky), including end-to-end tests. Dependencies should be replaced with fast, deterministic mocks in tests where possible. +- After a code change, neither the developer nor CI should rerun tests that cannot have been affected by the change. E.g. a pure mobile client change shouldn't rerun relay or desktop client tests, and vice versa. +- Tests and implementations should reflect the intended behavior described here and in applicable specs. + +## Release cycle + +- We want to minimize the average time elapsed between (a) merging a change and (b) the change appearing in Comp Portal and the app stores. +- We should always have a release `Waiting for Review` / `In Review` in the iOS App Store. Immediately a release is approved, we submit a new one. +- We should build and upload release candidates frequently. Every RC should go to Comp Portal and TestFlight.

The executable contract for the future +relay integration lives in +`tests/fixtures/relay-feature-selection`. + +## Composition Root Shape (artifact boundary) + +Construct once at process startup, then inject shared `Arc` +into server components. + +```rust +use std::sync::Arc; +use std::time::Duration; + +use buzz_feature_flags::{EnvironmentEvaluator, FlagEvaluator, StaticEvaluator}; +#[cfg(feature = "launchdarkly-feature-flags")] +use buzz_feature_flags::launchdarkly::{ + LaunchDarklyEvaluator, LaunchDarklyInitError, LaunchDarklyRuntimeConfig, + LaunchDarklyStartError, +}; + +#[cfg(not(any( + feature = "static-feature-flags", + feature = "environment-feature-flags", + feature = "launchdarkly-feature-flags", +)))] +compile_error!( + "select exactly one relay feature flag provider feature: static-feature-flags, environment-feature-flags, or launchdarkly-feature-flags" +); + +#[cfg(any( + all(feature = "static-feature-flags", feature = "environment-feature-flags"), + all(feature = "static-feature-flags", feature = "launchdarkly-feature-flags"), + all(feature = "environment-feature-flags", feature = "launchdarkly-feature-flags"), +))] +compile_error!( + "select exactly one relay feature flag provider feature: static-feature-flags, environment-feature-flags, or launchdarkly-feature-flags" +); + +#[cfg(any(feature = "static-feature-flags", feature = "environment-feature-flags"))] +#[derive(Default)] +struct FeatureFlagRuntimeConfig; + +#[cfg(feature = "launchdarkly-feature-flags")] +struct FeatureFlagRuntimeConfig { + sdk_key: String, + relay_proxy_endpoint: Option, +} + +struct RelayCompositionRoot { + feature_flags: Arc, + environment_diagnostics: Option>, + #[cfg(feature = "launchdarkly-feature-flags")] + launchdarkly_lifecycle: Option>, +} + +#[cfg(feature = "launchdarkly-feature-flags")] +enum RelayStartupError { + LaunchDarklyInit(LaunchDarklyInitError), + LaunchDarklyStart(LaunchDarklyStartError), +} + +#[cfg(feature = "static-feature-flags")] +fn build_feature_flag_evaluator(_config: FeatureFlagRuntimeConfig) -> RelayCompositionRoot { + RelayCompositionRoot { + feature_flags: Arc::new(StaticEvaluator), + environment_diagnostics: None, + } +} + +#[cfg(feature = "environment-feature-flags")] +fn build_feature_flag_evaluator(config: FeatureFlagRuntimeConfig) -> RelayCompositionRoot { + let _ = config; + let owner = Arc::new(EnvironmentEvaluator::from_process_environment()); + let feature_flags: Arc = owner.clone(); + RelayCompositionRoot { + feature_flags, + environment_diagnostics: Some(owner), + } +} + +#[cfg(feature = "launchdarkly-feature-flags")] +async fn build_feature_flag_evaluator( + config: FeatureFlagRuntimeConfig, +) -> Result { + let mut runtime_config = LaunchDarklyRuntimeConfig::new(config.sdk_key); + if let Some(relay_proxy_endpoint) = config.relay_proxy_endpoint { + runtime_config = runtime_config.with_relay_proxy_endpoint(relay_proxy_endpoint); + } + + let owner = Arc::new( + LaunchDarklyEvaluator::from_runtime_config(runtime_config) + .map_err(RelayStartupError::LaunchDarklyInit)?, + ); + owner + .start_with_default_executor_and_wait(Duration::from_secs(5)) + .await + .map_err(RelayStartupError::LaunchDarklyStart)?; + + let feature_flags: Arc = owner.clone(); + Ok(RelayCompositionRoot { + feature_flags, + environment_diagnostics: None, + launchdarkly_lifecycle: Some(owner), + }) +} +``` + +Each relay feature produces exactly one `build_feature_flag_evaluator` path, and +runtime config carries only the selected provider's settings. There is no +runtime provider enum, no provider-name environment variable, and no fallback +selector. + +Startup is fail-closed: if the selected provider fails initialization (including +`start_with_default_executor_and_wait` for LaunchDarkly), relay startup must +return an error and stop rather than falling back to another evaluator. + +The extra concrete `Arc` is an owner/lifecycle handle to that same evaluator, +not a layered provider. Consumers receive only the cloned `Arc` view. Retain the environment owner to drain diagnostics after +evaluations, and retain the LaunchDarkly owner so shutdown can call `close()`. + +`EnvironmentEvaluator` snapshots environment values once at construction, +retains only `BUZZ_FEATURE_FLAG_` entries, ignores `EvaluationContext`, and +never rereads process environment during evaluation. + +For deterministic tests or embedding, `EnvironmentEvaluator::from_pairs(...)` +constructs the same immutable snapshot from explicit key/value pairs. + +Environment entries are untyped at construction, so malformed present values +are detected when a typed flag is first evaluated. `take_diagnostics()` drains +each sanitized diagnostic at most once per flag key and expected type. The +composition root should retain the concrete environment evaluator and emit each +drained diagnostic as a warning through the application's logging stack. +Diagnostics contain no raw value or environment-variable name; the value +snapshot itself remains immutable. + +## `buzz-db` Boundary (approved correction) + +`buzz-db` may evaluate flags internally when choosing between equivalent query +implementations. It should depend on `buzz-feature-flags` without enabling the +LaunchDarkly feature, and it should never construct or import provider types. + +Concise example (query path selection only): + +```rust +use buzz_core::CommunityId; +use std::sync::Arc; + +use buzz_feature_flags::{EvaluationContext, FlagEvaluator, IntegerFlag}; + +pub struct Db { + feature_flags: Arc, +} + +impl Db { + pub async fn list_events( + &self, + community: CommunityId, + ) -> anyhow::Result> { + let context = EvaluationContext::for_community(community); + + let query_version = self.feature_flags.evaluate_int( + IntegerFlag::new("db.events.query-version", 1), + &context, + ); + + if query_version >= 2 { + self.list_events_v2_sql(community).await + } else { + self.list_events_v1_sql(community).await + } + } +} +``` + +SQL details are intentionally omitted in this example; the key point is that +public `Db` methods accept only domain inputs, while feature-flag evaluator +wiring remains internal to `Db` construction. + +`EvaluationContext::for_actor` is appropriate only when the existing DB +operation already receives an authoritative authenticated actor for domain +behavior. Feature targeting must not add actor/pubkey parameters to otherwise +actor-free DB APIs. + +For LaunchDarkly, the adapter context always includes kind `community` plus +optional global kind `pubkey`. Percentage rollouts must explicitly choose a +kind present in evaluation: rollouts must set `contextKind` to a kind present +in evaluation (`community` or `pubkey`) when they are intended to bucket Buzz +traffic. LaunchDarkly rollouts where configuration omits `contextKind` defaults +to `user`; Buzz does not synthesize a `user` alias, so those rollouts bucket as +zero and pick the first positive-weight variation. + +## Guardrails + +- Evaluation context inputs are authoritative server-resolved values + (`community`, optional `actor`), not client-supplied targeting attributes. +- Flags may choose between **equivalent** implementations only. +- Flags must not weaken authorization, tenant isolation, ordering guarantees, + transaction/consistency behavior, or schema invariants. +- Declared defaults choose the established safe path. +- Integer values must be validated at the consumer boundary before affecting + behavior. + +## Fallback, Startup, and Lifecycle + +- `StaticEvaluator` always returns each flag's declared default. +- `EnvironmentEvaluator` returns declared defaults when values are missing, + empty, invalid, non-Unicode, or the normalized flag key is unusable.

A session connected to a different +/// pod keeps its inert subscription state, but will not receive messages from +/// this channel: the cross-pod membership invalidation (step 1) ensures that +/// `filter_fanout_by_access` re-checks membership before delivery and denies +/// the removed user on every pod. The same pod-local eviction primitive is +/// used by the remove (kind 9001) and leave (kind 9022) paths; cross-pod +/// remote `CLOSED` frame delivery is not yet implemented (tracked separately). +/// 3. `disable_departed_member_workflows` — durably disables any workflows the +/// kicked user owned in this channel (SEC-006). +/// +/// These are identical to what `handle_remove_user` (kind 9001 path) fires after +/// removing a member.

Configure the App Attest +application ID and APNs topic explicitly before enabling the gateway. + +Stop old gateway instances and verify the migration prerequisites before +activation. The gateway migration refuses existing installations, and the relay +migration refuses active legacy leases; neither deletes registration state. + +### Platform-managed runtime integration + +`podLabels`, `serviceAccountName`, and `terminationGracePeriodSeconds` configure +only runtime pods. Defaults retain the existing pod specification; the grace +period cannot be shorter than 60 seconds. Additional labels cannot override the +chart's name, instance, or component selectors. Migration settings remain separate. + +A parent chart that supplies its own runtime NetworkPolicy can set +`networkPolicy.enabled=false` and `networkPolicy.externalPolicyName` to that +policy's name. The name is an explicit acknowledgement, not a cluster existence +check: the parent must render and validate a policy selecting the runtime pods +before deployment. Supplying a replacement name while the upstream policy is +enabled is rejected. The migration NetworkPolicy remains enabled independently. + +External-policy releases must run `tests/check-external-policy.rb` on the +**complete parent render including hooks**, before install or upgrade.

Missing Deployments or removed or +overwritten markers then fail closed. No-argument mode is only for renders that +intentionally have no external-policy requirement, such as default-mode tests. + +For upgrade preflight, include `--is-upgrade`. Deployment automation must stop if +this pipeline fails and must not change the chart or rendering inputs between +validation and deployment. Run the post-renderer additionally during Helm +install/upgrade to check ordinary resources, but retain the full-render preflight +to detect hook collisions. GitOps render pipelines must validate the complete +hook-inclusive output before submitting it to their reconciler. +The Deployment records the required policy name. The gate rejects a missing, +misspelled, duplicate, wrong-namespace or non-selecting replacement, and requires +both ingress and egress isolation. It emits no manifests on failure and preserves +successful output byte-for-byte. Parent CI must run this same gate on its complete +render; a subchart-only render intentionally fails in external-policy mode. +The deployment owner must separately validate the allowed traffic and rolling drain. + +## Deployment annotations + +Use `deploymentAnnotations` for Deployment metadata such as +`secret.reloader.stakater.com/reload`. These do not apply to runtime Pods or +migration Jobs.

No `other` operation or request-controlled/sensitive label is valid. +### Writer connection setup contract + +Writer connection setup is separate from checkout. At boot, SQLx constructs +the writer pool and creates its minimum physical connections. Later it may +create more when the pool grows or replaces a broken or expired connection. +Every connected writer session must install the created-at floor, install the +session timeouts, verify READ COMMITTED isolation, and reach `ready` before SQLx +can give it to a caller. + +| Metric | Type | Labels | +|--------|------|--------| +| `buzz_db_connection_step_started_total` | counter | `pool_role`, `step` | +| `buzz_db_connection_step_duration_seconds` | histogram | `pool_role`, `step` | +| `buzz_db_connection_step_attempts_total` | counter | `pool_role`, `step`, `outcome` | + +The fixed steps are `writer_pool`, `physical_connect`, `created_at_floor`, +`session_timeouts`, `isolation`, and `ready`. Measurable phases emit start, +duration, and terminal evidence. `physical_connect` and `ready` are success +milestones: SQLx 0.9 exposes `after_connect` only after DNS, network, TLS, and +authentication finish, so Buzz does not invent separate timings for those +internal phases. Raw connect failures before `after_connect` are classified on +the aggregate `writer_pool` phase during initial construction. Outcomes are +`succeeded`, `failed`, `timed_out`, and `cancelled` where valid. + +For a measurable phase on one pod, subtract all terminal outcomes from its +start counter to derive the number of attempts currently in progress. The +session phases run in order, so a later phase start also proves the earlier +phases succeeded for that attempt. + +Four start counters, four 13-series histograms, and fifteen terminal counters +create a hard ceiling of 71 raw Prometheus series per pod. Connection ordinals, +database URLs, hosts, usernames, SQL, and raw errors are forbidden as metric +labels. + +When audit logging is enabled, the `buzz_db_connection_*` metric totals combine +the main writer pool and the separate audit writer pool. + +### Physical database pool utilization and configuration contract + +Every physical Postgres pool the relay owns reports current utilization, +capacity, and configuration under role-labelled families. The role vocabulary +is closed — `writer`, `reader`, `audit`, `search` — and all four roles are always +present, so a series never appears or disappears when an optional pool is +enabled or disabled. An unconfigured optional pool reports +`buzz_db_pool_configured` `0` with zero utilization and capacity rather than +going missing. + +| Metric | Type | Labels | +|--------|------|--------| +| `buzz_db_pool_connections` | gauge | `pool_role`, `state` | +| `buzz_db_pool_max_connections` | gauge | `pool_role` | +| `buzz_db_pool_configured` | gauge | `pool_role`; `1` configured, `0` not configured | + +States are `idle` and `active`; their sum is the pool's current size. +`buzz_db_pool_max_connections` reports capacity separately, so summing the +connections family counts each current connection exactly once. The three +families are fixed at 16 raw Prometheus series per pod (`4 × 2` current +utilization plus `4` maximum capacity plus `4` configured). The `audit` and +`search` roles are statistics-only: pool ownership, capacities, timeouts, and +query routing are unchanged, and these roles emit no acquisition telemetry. + +The pre-existing unlabelled `buzz_db_pool_*` (writer) and `buzz_db_read_pool_*` +(reader) gauges are still exported unchanged for dashboard compatibility. The +reader family remains absent when no read replica is configured; use +`buzz_db_pool_configured{pool_role="reader"}` for the explicit signal. + +Pool sizing and the aggregate connection budget across all four roles remain +deployment configuration concerns. The relay does not enforce a combined +connection ceiling. + ## Relay Pod extensions The chart exposes narrow extension points for init containers, volumes, relay @@ -239,6 +460,85 @@ volumes, and each init container must define an appropriate security context and resources. Empty `relay.command` and `relay.args` arrays preserve the image defaults; non-empty values override its entrypoint and arguments respectively. +## Storage accounting worker + +`storageAccounting.enabled=true` adds a CronJob that runs +`buzz-admin storage-snapshot` against the relay's S3 bucket and writes a +durable snapshot row, keeping the expensive object walk off the relay Pods. + +### Snapshot identity contract + +Every snapshot row records the code that produced it in `code_sha`, taken from +the `BUZZ_STORAGE_SNAPSHOT_CODE_SHA` environment variable the chart derives +from the deployed image identity (`image.digest` when set, otherwise +`image.tag`, otherwise `Chart.AppVersion`). The value is never hashed or +sanitized. + +## Datadog version label + +Every Pod the chart renders — relay, pairing relay, storage accounting, and the +deletion drain operator job — carries a chart-owned +`tags.datadoghq.com/version` label derived from the deployed image: +`image.tag` when set, otherwise `image.digest`, otherwise `Chart.AppVersion`. +The tag is preferred because it is the readable build name (`sha-`) +dashboards already use; promotion tooling writes it together with the digest +that actually pins the image. + +```yaml +relay: + podLabels: + tags.datadoghq.com/env: production + tags.datadoghq.com/service: buzz + # tags.datadoghq.com/version: NOT set here — the chart owns it. +``` + +Precedence is explicit: a `tags.datadoghq.com/version` supplied under any +workload's `podLabels` is ignored. Every other label — including +`tags.datadoghq.com/env` and `tags.datadoghq.com/service`, which describe the +deployment rather than the image — passes through unchanged. Remove any +wrapper-maintained version pins when upgrading; a pin equal to `image.tag` +renders identically, so the upgrade does not roll Pods for that label. + +A Kubernetes label value is capped at 63 bytes, must begin and end with an +alphanumeric, and may otherwise contain only `[-._a-zA-Z0-9]` — a far narrower +grammar than an OCI tag. `image.tag` is deliberately left unconstrained, so the +label is derived through a total mapping rather than a check that could reject +a tag the chart used to accept: + +| Revision | Label | +|---|---| +| `sha256:<64 hex>` digest | the hex without `sha256:`, first 63 characters | +| already a valid label value, lowercase, no `__`, and not exactly 63 lowercase hex characters | emitted byte for byte (e.g. `1.2.3-rc.4`, `sha-1a2b3c4`) | +| anything else | the first 63 hex characters of the revision's SHA-256 | + +The passthrough row requires Datadog's normal form because Datadog lowercases +tag values and collapses `__`: passing `ReleaseA` and `releasea` through +unchanged would report one version for two revisions. Every emitted label is +therefore already normalized, so distinct labels stay distinct in Datadog. + +When both `image.tag` and `image.digest` are set, the label names the tag — +even if the tag and digest disagree. The digest still pins what actually runs +(`repository@digest`), so keep the two in step when promoting. + +Exactly 63 lowercase hex characters is a **reserved shape** — it is what the +first and third rows emit, so the passthrough row must not be able to emit it +too. A tag of that shape is hashed rather than preserved. Shorter hex tags and +ordinary 40-character git SHAs are unaffected. + +Arbitrary OCI revisions outnumber 63-byte label values, so **no mapping onto +this grammar can be injective** and the chart does not claim one. What it does +claim is collision *resistance*: every case retains 252 bits of SHA-256, the +same margin the digest case has always relied on, and the reserved shape keeps +that margin across cases rather than only within one. Two earlier iterations +fell short of this — one kept a readable prefix with only 40 bits of hash (a +colliding tag pair was brute-forced in about a second), and one let a +passthrough tag reproduce a hashed label with no hash work at all, by copying a +rendered label into `image.tag`. + +The image reference in the Pod spec and `BUZZ_STORAGE_SNAPSHOT_CODE_SHA` always +keep the exact revision; the label is the joinable telemetry key.
