Rename the project spec and update every reference to it
The charter file carried a tool-specific name while being the repository's own document: mission, non-negotiable constraints, the pinned stack, repo conventions and phase status, cited as authority by thirty files across the agent, api, deploy, docs, search and terraform trees. PROJECT-SPEC.md says what it is. All 42 references are updated in the same commit, including the relative link in docs/status.md, so nothing points at a filename that no longer exists. |

Complete the low-risk half of the Sentry -> Cairn OBS rebrand
Sweeps the references that carry no runtime coupling, and fixes one that
turned out to be a real bug rather than stale branding.
Docker network: sentry_default -> cairnobs_default across 23 runbook and
test-header `docker run` commands. Compose derives the network from the
directory name, so this lands together with renaming the working copy to
cairnobs/ -- the two are only correct as one change.
Stale references corrected: four Dockerfile "repo root (sentry/)"
headers; .env pointing at the long-renamed deploy/helm/sentry/ chart;
five Helm comments describing the topic as sentry.logs.raw when all four
code paths have defaulted to cairnobs.logs.raw for some time; an
absolute /home/john/Projects/sentry/ path in the operator's package doc,
now repo-relative; the hand-written Tenant CRD description in both of
its identical copies, whose Go source already said Cairn OBS.
Migration 0043 repoints the default tenant's data source. 0026 seeded it
with ('sentry', '/var/lib/sentry-search') to match what
api/internal/config then defaulted to; the rebrand later moved those
defaults to "cairnobs" and /var/lib/cairnobs-search without moving the
already-applied row, leaving the default tenant naming a ClickHouse
database nothing writes to. Scoped to the exact stale values so it is a
no-op on any deployment that set them deliberately. 0026's comment is
annotated as superseded; its applied SQL is untouched.
Deliberately not included: the gRPC wire packages (sentry.logs.v1,
sentry.agent.v1) and proto/sentry/ import paths, which cannot change
without a lockstep agent/server upgrade; the Helm chart's
sentry_metadata database and sentry role, which need a real Postgres
migration on existing deployments; and the compliance audit records in
docs/compliance/, which are a dated historical record.
go build, go vet, and go test pass for ingest and deploy/operator.

Let each user pick the timezone timestamps are displayed in
Everything stays UTC: ingest still records Unix nanoseconds, ClickHouse
still stores UTC, every API response is still RFC3339 with a Z, and
queries are evaluated exactly as before. This changes only how those
instants are written on screen, so two people in two timezones looking
at one log line see the same instant written two ways -- never two
different lines, and never a different sort order.
Where the preference lives differs by deployment, and the three cases
are genuinely different products rather than one with fallbacks:
- Local login: server-side per named user (display_timezone on users,
PUT /auth/timezone), so it follows the person across browsers and
survives logout. Self-service at the RoleViewer floor, same as the
password change -- a viewer is the role most likely to be *only*
reading logs, so gating it higher would make it useless.
- Public demo: sessionStorage, so every new session starts at UTC. A
shared account's visitors have nothing to do with each other.
- Neither: localStorage, since there's no per-user record to write to.
api/cmd/api/main.go now imports time/tzdata. The image is
distroless/static with no /usr/share/zoneinfo, so LoadLocation would
otherwise reject every real zone name and the validation would refuse
every valid input.
Two details worth knowing when reading $lib/time.ts. Sub-second digits
are copied verbatim from the source string rather than round-tripped
through a JS Date, which is millisecond-precision and would silently
drop six digits of a ClickHouse nanosecond timestamp; expanding a result
row shows the localized value and the full-precision UTC original
together. And chart axes format their own labels, because ECharts'
type: 'time' axis renders in the browser's zone with no override --
which today puts a chart's clock out of step with the table beside it.
Timestamps are detected by value, not by column name: query output is
arbitrary, so a column called "timestamp" holding something else must
not be mangled, and `stats max(timestamp) as newest` must still be
formatted.
Verified against real zones including both sides of a DST boundary
(America/New_York at -05:00 in January, -04:00 in July), a half-hour
offset, and date rollover.

Finish the Cairn OBS rename through services, docs, and assets
The rename commit before this one covered module paths and the obvious user-facing strings; this is the rest of it -- the places where "sentry" was a default value, a filename, or a picture rather than a word in a sentence. Defaults that changed: CLICKHOUSE_DATABASE (sentry -> cairnobs), POSTGRES_DATABASE (sentry_metadata -> cairnobs_metadata), and POSTGRES_USERNAME (sentry -> cairnobs), across api/alerting/ingest and the enterprise binaries, plus the compose files and migrate scripts that create those objects. These are *defaults*, so a deployment that sets them explicitly is unaffected -- but any deployment relying on the old defaults must have its environment updated before it picks this up, or it will come up pointing at a database that doesn't exist. Also: the light-mode logo variants (the dark ones existed alone, so the landing page and sidebar rendered a dark mark on a light background), regenerated favicons, and the docs/README/threat-model prose that still said Sentry. |

Rebrand: Sentry -> Cairn OBS
Full rebrand across cosmetic branding, code identifiers, and infrastructure/data-plane naming, using the supplied Cairn OBS logo package. Cosmetic: favicon/logo swap (also closes a stale license-audit finding -- the old favicon was SvelteKit's unreplaced scaffold logo), new centered welcome landing page, larger/legible sidebar logo, page titles, CLAUDE.md/README/docs prose. Code identifiers: Go module path github.com/sentry/sentry -> github.com/cairnobs/cairnobs across all 13 modules and ~91 files (protoc regenerated); Rust crates sentry-agent/sentry-parser/sentry-search -> cairnobs-*; CLI sentryctl -> cairnobsctl; Terraform provider fully renamed (sentry_dashboard etc. -> cairnobs_dashboard, provider type, env vars); every session/auth cookie name; agent config paths and Windows service identity. Deliberately preserved: the gRPC wire protocol's protobuf packages (sentry.logs.v1, sentry.agent.v1) and their Go import directory (proto/sentry/...) -- renaming the wire-level package would break every currently-deployed agent binary (confirmed two real hosts, including mail.inbuxa.com, are actively streaming through this exact contract) until rebuilt and redeployed in lockstep with an ingest cutover. Only the Go module path wrapping the generated code changes. Infrastructure: every docker-compose container name (root and three component-level compose files); the Helm chart (directory, Chart.yaml, named-template helpers, all templates, values.yaml image repos); Kubernetes Operator (CRD group sentry.io -> cairnobs.io, both CRD YAML files, Go identifiers, RBAC markers); the coupled enterprise/tenantcrd package. Caught and fixed real path-coupling bugs along the way: the Helm chart's search/ingest volume mounts and the dev-only-credential detection constant vs. docker-compose.yml's literal values had to move together or a security warning would have silently stopped firing. Data plane: Postgres database sentry_metadata -> cairnobs_metadata and role sentry -> cairnobs; ClickHouse database sentry -> cairnobs; Kafka topic sentry.logs.raw -> cairnobs.logs.raw and its consumer groups. Source-level defaults, docker-compose.yml, and every migrate.sh/ provision script default updated together; already-applied migration files left untouched per this repo's immutable-migration convention. Verified at every layer: all 13 Go modules build/vet/test clean, both Rust workspaces (agent, search) build/clippy/test clean, npm run check/ build clean, docker compose config validates on all four compose files. Live-verified against a real docker stack multiple times through this work, including a final fresh-volume run confirming the actual renamed Postgres database/role, ClickHouse database, and Kafka topic all work end to end with a real login and query, zero console errors. |

Add local login, agent extra log paths, IPv4/IPv6 metrics; remediate security audit findings
This is a large squashed commit covering two batches of prior uncommitted work plus a full security-audit remediation pass, kept together because go.mod/go.sum and several shared files (main.go, handler.go) were touched by both and splitting risked non-building intermediate commits. Features (built earlier, previously uncommitted): - Local username/password login for single-tenant deployments with no SSO configured (api/localauth, alerting/internal/sessioncheck, sentryctl users, web/src/routes/login, metadata migrations 0040/0041). - Remotely-editable additional log file paths for agents, on top of their existing primary source (api/agents, agent/sentry-agent extra-file-path diffing, web agent config UI). - IPv4/IPv6 addresses reported alongside other host system metrics. Security audit remediation (this pass, all live-verified in production): - Critical: block ClickHouse SSRF table functions (url/remote/file/s3/...) in the raw-SQL query escape hatch. - High: deny sensitive paths and require Admin to add agent extra_file_paths (Editor could previously point an agent at /etc/shadow or an SSH key); alerting webhook targets now validate against internal/metadata/loopback addresses, both at creation and send time; alerting's session middleware now enforces an Editor+ floor on mutating requests instead of "any authenticated session"; bumped goxmldsig to close a SAML signature-verification bypass (GO-2026-4753). - Medium: per-IP login rate limiting; security response headers (HSTS/CSP/nosniff/X-Frame-Options/Referrer-Policy/Permissions-Policy) on web/nginx.conf; a DevCredentialWarnings check in every Go service's config loader, logging loudly at startup if a deployment is still on docker-compose.yml's literal dev-only credentials; dependency bumps (golang.org/x/text, grpc, x/net, quick-xml, h2) across every affected Go module and both Rust crates, including a previously-uncovered x/net vulnerability in deploy/operator; a new security-scan.yml CI workflow running cargo-deny/govulncheck/npm-audit, mirroring the existing license-compliance.yml matrix shape. - Low: removed sentryctl's plaintext --password flag (shell history/`ps` exposure) in favor of stdin and a --password-stdin flag for reset-password's optional specific-password path; a dummy bcrypt comparison closes a login response-time username-enumeration side-channel. |

Add agent restart lifecycle command
Extends the existing CheckIn RPC with a one-shot AgentCommand (restart only -- stop/uninstall need real per-platform OS service-manager integration and stay deliberately out of scope), delivered at-most-once: cleared the instant it's handed to the agent in a response, since a restarting agent's process is gone before it could ever confirm receipt. On restart, the agent flushes whatever's buffered, aborts its source task, and exits cleanly, relying entirely on the host's own service manager to bring it back up. Issuing a command is gated at RoleAdmin (stricter than config editing's RoleEditor) and logged into the same audit_log table Phase 7's AI interactions use, via a new agent_command event type. A real bug was found and fixed during live verification: the first implementation tried to atomically read-and-clear pending_command in a single INSERT...ON CONFLICT statement using a sibling CTE referenced only from RETURNING, on the assumption that Postgres evaluates every part of a WITH query against one pre-statement snapshot. That's wrong specifically for FOR UPDATE, which always reads the latest row version including one written earlier in the same statement -- confirmed empirically (a restart command was always coming back empty even when genuinely pending, so the agent never received it). Fixed by splitting into two real, ordered statements inside one explicit transaction. See /docs/agent-management-design.md's "Lifecycle commands" section. |

Add agent inventory, management, and remote config
Extends the heartbeat mechanism with a second gRPC service on the same mTLS channel (AgentControl.CheckIn, agent-initiated on the existing heartbeat ticker -- still push-only, no inbound port on any agent) so an agent reports its running config and can pick up an operator-set override. A new web UI section (/agents) lists every agent that's checked in, shows its reported config, and lets an operator edit a narrow, deliberately-scoped subset remotely: batch/heartbeat tuning, and (journald sources only) the unit filter. TLS material and the ingest endpoint are never reportable or remotely editable, by proto shape rather than a validation rule -- a bad or malicious edit there could permanently strand an agent or redirect where its logs go, unlike every other editable field, which only degrades behavior. An override lives only in the agent's memory (agent.toml is never rewritten) and re-syncs on the agent's own schedule; changing the journald filter aborts and respawns the source task since there's no other way to change what's being tailed. Building the hot-reload path surfaced a real, independent, pre-existing bug: shutdown was using poll_timeout(), which only drains once flush_interval has elapsed, silently dropping anything buffered more recently on every graceful shutdown that landed between flushes -- fixed with a new unconditional Batcher::flush_all(), now used at both shutdown and hot-reload. Verified live end-to-end against a real stack: an edited heartbeat interval changed a running agent's actual send cadence within one check-in cycle (confirmed by the real timestamps landing in ClickHouse), and an edited journald filter triggered a real source restart, both reflected back in the next reported-config snapshot. See /docs/agent-management-design.md. |

Phase 7: AI-assisted query authoring (autocomplete, explain, fix, optimize, NL translation)
Adds a self-hosted (Ollama, qwen2.5-coder) model provider abstraction with a pluggable opt-in cloud adapter, schema grounding, and a shared cost/safety guard every AI-suggested query is assessed against -- compiling to and executing through the same unchanged Phase 2 IR/ compiler and Phase 4 tenant scoping as a hand-written query, no parallel execution path. Track A (built into the query bar): inline ghost-text autocomplete, "Explain this query", "Fix this query" with a diff view, and a rule-based "Optimize" suggestion. Track B: natural-language-to-query translation, always a separate review step from execution, with `sentryctl query --nl` requiring explicit confirmation to run. Every accepted/dismissed translate-fix-optimize interaction is logged into the same append-only audit_log table Phase 4 built. Two real product bugs were found and fixed via live browser verification (a Svelte effect re-running on every keystroke that silently cancelled the ghost-text debounce; a ghost-text widget positioned at document offset 0 instead of the cursor), and a real costguard logic bug (unbounded-aggregation vs. raw-row) was caught by its own test suite. New integration tests wire a real Ollama client through the real HTTP handler against a mock server matching Ollama's wire contract (hack/mock-ollama), keeping model-quality verification out of CI as a disclosed, periodic human-run check instead. See /docs/phase-7-ai-design.md and /docs/phase-7-runbook.md. |

Add a real charting layer and a heatmap panel type
Five chart types on ECharts (modular imports, not the full bundle):
TimeSeriesChart (multi-series, legend toggle), BarChart (incl.
stacked), SingleStat (big number + sparkline + trend), Heatmap, TopN.
Shared interactions: tooltips, dataZoom feeding the global time-range
picker, click-to-drill-into-query (drilldown.ts strips a panel's query
to its pre-stats filter and appends the clicked series/x-value as a
new filter term -- no backend change needed).
pivot.ts reshapes the query language's existing {columns, rows} tabular
output into per-series chart data client-side -- `stats count by
service, timestamp` already returns "long" rows, so multi-series
support needed zero query-language changes. theme.ts reads real
computed CSS custom properties so charts render in the active theme's
actual colors, with an SSR_FALLBACK for adapter-static's prerender pass
where `document` doesn't exist.
heatmap is the one narrow, justified backend change: a new VizType
needed to feed a new visualization, not a new query capability. Three
places had to change together, not two -- api/dashboards/types.go's
validator, web/src/lib/api.ts's union (previous commit), and the
dashboard_panels table's viz_type CHECK constraint
(migrations/0035_add_heatmap_viz_type.sql), which mirrors the Go
validator and doesn't update itself.
/dev/charts (unlisted, dev-only) is a synthetic fixture/perf-test route:
confirmed 50ms first-two-frames render time on a production build
against a 30,006-row/6-series stress case, and a 211,975-byte gzipped
chart chunk -- both real measurements behind the ECharts-over-
Observable-Plot-or-D3 choice, not estimates.

Give ingest a real tenant identity (write-routing deferred, disclosed)
Ingest tenant-awareness was named "undesigned, not just unbuilt" across CLAUDE.md/threat-model.md/the runbook since early Phase 4 -- the last major standing gap. Scoping was agreed via AskUserQuestion: a config-supplied tenant_id + shared-secret token ingest validates (smaller real implementation, no new PKI), over per-tenant mTLS certs. This change builds that identity mechanism end to end and attaches it to every record at the point it enters the system; it deliberately does NOT build per-tenant write-routing for ClickHouse or Tantivy -- that's real, separately-scoped follow-up work, disclosed explicitly everywhere this was previously called undesigned, not silently left half-done. New pieces: - metadata/migrations/0034 + enterprise/internal/rbacstore/ ingest_credentials.go: a per-tenant bearer credential, only its SHA-256 hash ever persisted (same reasoning a password gets hashed, not stored raw) -- CreateIngestCredential returns the plaintext exactly once, ValidateIngestCredential/RevokeIngestCredential/ ListIngestCredentialsForTenant round it out. - enterprise-auth gains -create-ingest-credential-tenant/ -list-ingest-credentials-tenant/-revoke-ingest-credential (same offline-operator-flag shape as every other credential-minting flag in this binary) and a new POST /internal/authorize-ingest endpoint (internal/authhandler) validating a presented token and resolving its tenant -- a genuinely different credential type from session-backed /internal/authorize, so it doesn't touch session.Manager at all. - ingest (AGPL core) gains an optional TenantResolver (internal/grpcserver, nil by default) and its HTTP client implementation (internal/tenantresolver.HTTPResolver) -- a plain HTTP call to enterprise-auth's new endpoint, never an enterprise/ import, same "network boundary, not import boundary" shape api/authz.HTTPAuthorizer already uses for the query path. PushBatch now requires an `authorization: Bearer <token>` gRPC metadata entry once a resolver is configured, fails the whole batch closed on a missing/invalid credential (never falls back to "no tenant"), and attaches the resolved tenant ID to every record as a `tenant_id` Kafka message header before producing it. Verified with real round trips at every layer, no Docker needed: rbacstore's credential CRUD (skip-gated on live Postgres, same as every other rbacstore integration test this phase), authhandler's new endpoint (real HTTP via httptest, including the regression test that a session token must not validate as an ingest credential), tenantresolver (real HTTP client against httptest, same pattern as authz.HTTPAuthorizer's own tests), and grpcserver's PushBatch (fake resolver/producer -- no resolver leaves messages unchanged, a configured resolver attaches the right header or fails closed on a bad/missing token). Helm: ingest.requireTenantCredential (default false) is a deliberate, separate opt-in from enterprise.enabled -- turning ENTERPRISE_AUTH_URL on for ingest requires every agent to already hold a credential or be refused outright, so it must not default on just because enterprise.enabled does (same reasoning api.yaml's ENTERPRISE_AUTH_URL isn't tied to enterprise.enabled directly either). docker-compose.yml leaves it unset, same as ever. Docs updated everywhere this was called "undesigned": CLAUDE.md, docs/architecture.md, docs/security/threat-model.md (including its summary table, now split into "identity: built" vs "write-routing: not yet"), docs/phase-4-runbook.md (new §13), enterprise/README.md. |

Enforce per-resource dashboard grants (RBAC matrix's own/granted qualifier)
api/dashboards' handler previously enforced only tenant-baseline role
(RoleEditor+), so any Editor could edit/delete any dashboard in their
tenant -- the matrix's "(own/granted)" qualifier was explicitly named
as unbuilt in this handler's own doc comment. This closes that gap.
New core interface api/dashboards.PermissionStore (nil-safe, same "not
wired == no-op" shape as authz.Authorizer) resolves a per-resource
dashboard_permissions grant. canEditDashboard now requires the
identity be Admin/Owner, the dashboard's creator, or hold a grant of at
least Editor; canManageGrants is deliberately stricter (creator or
Admin/Owner only, never grant-derived access) so a user who can edit a
dashboard only because of a grant can't extend or re-grant that access
to themselves or others. Wired handlers: PUT/DELETE
/dashboards/{id}/permissions/{userId}, GET .../permissions.
Two real bugs found and fixed while wiring this up, before any of it
touched a live database:
- handleCreate/handleImport never stamped created_by from the
authenticated identity, so every dashboard was owned by "anonymous"
regardless of who made it -- the ownership check would have been
meaningless. Also fixed: ImportDashboard trusted the exported JSON's
created_by verbatim, so re-importing someone else's export would
leave the actual importer unable to edit their own copy.
- metadata/migrations/0024_create_dashboard_permissions.sql's CHECK
constraint diverged from /docs/phase-4-rbac-design.md's schema
(allowed role='admin', nullable granted_by). Reconciled via
0033_restrict_dashboard_permissions_role.sql: Admin/Owner already
have tenant-wide access so a resource-level "admin" grant is
meaningless, and every real grant now always has an attributable
granter.
enterprise/internal/rbacstore gets the storage side: raw CRUD
(dashboard_permissions.go) plus DashboardPermissions
(dashboards_adapter.go), an adapter implementing
api/dashboards.PermissionStore -- same pattern as audit.QueryAPILogger
over queryapi.AuditLogger. Wired into enterprise/cmd/enterprise-api
only; plain api/cmd/api passes nil (ownership/Admin checks still work
via the nil-permissions fallback, just without the "granted" bonus).
Verified: the full own/granted/admin/creator matrix, including the
granted-editor-cannot-manage-grants regression, passes against a fake
PermissionStore (api/dashboards/handler_test.go, all existing tests
also still pass unmodified in behavior). Real integration tests exist
in enterprise/internal/rbacstore/rbacstore_test.go (skip-gated on
RBACSTORE_TEST_POSTGRES_ADDR, same convention as every other
Postgres-backed piece this phase) but have not run against a live
database in this environment -- disclosed in threat-model.md,
phase-4-runbook.md, and enterprise/README.md alongside every other
piece carrying the same gap. Also fixed a stale path in
phase-4-runbook.md's dashboards-tenant-scoping section
(./internal/dashboards/... -> ./dashboards/..., stale since that
package moved out of api/internal/ earlier in this phase).

Phase 4: real per-tenant ClickHouse isolation via a new enterprise-api binary
Closes the threat model's headline finding for the SQL query path:
enterprise/internal/tenantprovision does real CREATE DATABASE/USER/GRANT
against ClickHouse, and enterprise/internal/chrunner is a per-tenant
connection registry implementing api's SQLRunner interface, resolving
the tenant from the authenticated request identity -- never a
caller-suppliable parameter. Both are wired into a new binary,
enterprise/cmd/enterprise-api, alongside the unchanged single-tenant
api/cmd/api, since AGPL core can never import enterprise/ and Go's own
internal/ package visibility rules meant enterprise/ couldn't implement
core's SQLRunner interface without importing the package that defines
it. That required moving api/internal/{authz,queryapi,dashboards,
querylang/executor,searchclient,httpserver} out of internal/ -- the
minimal set enterprise-api needs to import; querylang's compiler
internals (planner/lexer/parser/ast/ir) and api's own config stay
internal, since nothing outside api needs them directly.
Also finally wires enterprise/internal/audit into queryapi.AuditLogger
(nil since Phase 4 task 4) via a new adapter, and adds live-ClickHouse
integration tests for two of the four adversarial probes named in
docs/phase-4-isolation-design.md's verification plan.
Corrected several overclaims in the docs while writing this up: an
earlier claim that rbacstore's CRUD was "verified against a live
Postgres" was never actually true in this environment (only
internal/audit was, earlier in this phase, before Docker access was
lost) -- threat-model.md, phase-4-runbook.md, CLAUDE.md, and
enterprise/README.md all now distinguish "a real integration test
exists" from "this was confirmed against a live database."
Still not built: Tantivy/free-text tenant isolation
(enterprise/internal/searchclient), and any deployment-topology
mechanism that actually routes traffic to enterprise-api instead of
plain api -- both binaries exist side by side today with nothing
enforcing or flagging which one a deployment runs.

Phase 4: SSO scaffolding, RBAC enforcement, tenant-scoped dashboards, audit logging, K8s deployment
RBAC (api/internal/authz) is live on /query and /dashboards, backed by a new enterprise/ module (session issuance, audit logging, RBAC storage, OIDC/SAML protocol wiring) that core never imports -- only calls over HTTP. Found and fixed a real cross-tenant vulnerability in dashboards (no tenant_id filtering at all) while writing the threat model doc. Two things are explicitly NOT done, documented rather than hidden: tenant isolation for log data itself (/query still shares one ClickHouse connection and Tantivy index across every tenant -- RBAC controls who can query, not what a query can see), and human SSO login (protocol wiring exists, no HTTP handler calls it yet). See docs/security/threat-model.md and docs/phase-4-runbook.md. Also adds deploy/ (Go Operator + Helm chart, validated offline only -- no cluster was reachable in this environment). |

Phase 3: dashboards and alerting
Saved, shareable multi-panel dashboards (table/line/bar/single-stat panels via gridstack + uPlot, global + per-panel time range, JSON export/import) and threshold/absence alert rules with an ok/pending/firing evaluator and webhook/Slack/PagerDuty delivery. - New /metadata component: Postgres control-plane store for dashboards, panels, notification targets, alert rules/state, and delivery log -- see docs/phase-3-dashboard-design.md for why ClickHouse's MergeTree family isn't a fit for this access pattern (needs real row-level locking and read-your-writes consistency). - api/internal/dashboards: dashboard/panel CRUD, pure -- panel query execution stays client-side, reusing the existing /query endpoint. - New /alerting service: rule/target CRUD, a ticker-driven evaluator (claim-then-evaluate concurrency control, transactional-outbox delivery, query errors and threshold zero-rows never coerced into a false transition) and webhook/Slack/PagerDuty delivery with retry/backoff. See docs/phase-3-alerting-design.md for the full state-machine design and the four correctness properties it implements. - web: /dashboards and /alerts UIs; cli: sentryctl dashboards/alerts list/get/apply, seeding a future Terraform provider's JSON contract. - hack/alert-load-test: 500 rules against real ClickHouse data, real measured results in docs/phase-3-runbook.md. Five real bugs found by actually running this against a live stack (documented in the runbook, not just fixed silently): a latent Phase 2 bug where ClickHouse rejected the timestamp format used for earliest=/latest= queries; a "now" literal token injected into query text; a GridStack/uPlot layout-timing race; JS's Date.parse being too lenient to use as a timestamp-detection heuristic; a rule's "enabled" field silently defaulting to false when omitted; and the evaluator's claim-batch-size and worker-pool-concurrency defaulting to the same value, causing 500 concurrently-due rules to take 125s to cycle through instead of the configured 60s. |
