{"slug":"current_slice_metrics","filename":"current_slice_metrics.csv","schema_markdown":"# current_slice_metrics.csv\n\n**Purpose:** declares the metrics you currently track on the live system,\nsliced by deployment segment (so Bridge can reason about deployment-context\ncalibration).\n\n**Required columns:**\n\n| Column | Type | Required | Description |\n|---|---|---|---|\n| `slice_id` | string | yes | stable identifier for this deployment slice (e.g., `geo:us-east`, `tenant:enterprise`, `traffic:beta`) |\n| `slice_description` | string | yes | human-readable slice meaning (≤200 chars) |\n| `metric_name` | string | yes | metric tracked on this slice (e.g., `success_rate`, `p95_latency_ms`, `customer_csat`) |\n| `metric_value_current` | float | yes | most recent observed value |\n| `metric_value_baseline` | float | no | pre-deployment baseline (if available) |\n| `observation_window_start` | ISO-8601 date | yes | start of observation period |\n| `observation_window_end` | ISO-8601 date | yes | end of observation period |\n| `sample_size` | int | yes | number of requests / users / cases observed in this window |\n| `notes` | string | no | free-form notes |\n\n**Minimum row count:** 3 (at least 3 distinct slices; one-slice systems hide deployment-context heterogeneity)\n\n**Example:**\n\n```csv\nslice_id,slice_description,metric_name,metric_value_current,metric_value_baseline,observation_window_start,observation_window_end,sample_size,notes\ngeo:us-east,US East datacenter primary region,p95_latency_ms,340,290,2026-05-01,2026-05-31,12500,canary deploy\ngeo:eu-west,EU West datacenter,p95_latency_ms,510,420,2026-05-01,2026-05-31,8700,higher tail\ntenant:enterprise,Enterprise tier customers,success_rate,0.91,0.87,2026-05-01,2026-05-31,3200,top-3 accounts excluded for privacy\n```\n\n**What this CSV is NOT:**\n- Not a metrics dashboard export (Bridge needs the slice structure explicitly; not a raw time-series dump)\n- Not a Prometheus query result (interpretive structure; not raw observability data)\n- Not aggregate-only (Bridge needs slice-level decomposition; the all-up number alone is uninformative for calibration)\n\n**Canonical source:** `bdc-bridge-passport` repository at frozen SHA recorded in `PASSPORT_REPO_PIN.md`.\n","page_url":"/passport/schemas/current_slice_metrics","template_url":"/passport/template/current_slice_metrics","canonical_source":"https://github.com/malishomen/bdc-bridge-passport"}
