+# Jenner compatibility tests
+
+[Jenner](https://jenneranalytics.com) is a complete SAS-compatible system
+and collaborative workspace. Each `tNNN_*` directory in this folder is a
+self-contained test bundle that submits a SAS program to the public API
+at `https://api.jenneranalytics.com/v1/run` and checks the response.
+
+## Bundle layout
+
+```
+tNNN_*/
+├── script.sas      # the SAS program
+├── autoexec.sas    # options + setup that prepend the script
+├── input/          # sample data the script reads (if any)
+├── expected.json   # stable assertions checked on each run
+├── expected/       # captured snapshot from the last passing run
+│   ├── log.txt     # the .log field, verbatim
+│   ├── output.txt  # the .output (listing) field, verbatim
+│   └── files.md    # links to ODS images, datasets, etc.
+└── meta.json       # provenance: source file, blob sha, what was adapted
+```
+
+## Running a bundle
+
+The runner concatenates `autoexec.sas` + `script.sas`, POSTs to
+`https://api.jenneranalytics.com/v1/run`, and prints the result.
+
+**Mac / Linux (bash + curl):**
+
+```bash
+./run_jenner.sh --all              # run every tNNN_* bundle, summary at end
+./run_jenner.sh t001_something     # run one
+./run_jenner.sh --list             # list bundles in this directory
+```
+
+**Windows:**
+
+```cmd
+run_jenner.bat tNNN_something
+```
+
+**From any SAS session (no curl needed):**
+
+Submit `run_jenner.sas` — it uses PROC HTTP to POST and prints the
+response.
+
+**By hand with curl:**
+
+```bash
+cat tNNN_*/autoexec.sas tNNN_*/script.sas > /tmp/submit.sas
+curl -sS -X POST https://api.jenneranalytics.com/v1/run \
+  -F "script=@/tmp/submit.sas" \
+  -F "deterministic=1" -F "timeout=60"
+```
+
+**Or in the hosted workspace:**
+
+Open <https://jenneranalytics.com>, paste `script.sas` (with the
+`autoexec.sas` lines prepended), upload anything in `input/`, and run.
+
+## Artifact URLs
+
+`expected/files.md` in each bundle lists hosted URLs for any ODS images,
+datasets, or other artifacts produced by a captured run. Those URLs are
+tied to a specific run and expire when the run is reaped — re-run the
+bundle to refresh them.

+/* run_jenner.sas — invoke api.jenneranalytics.com from base SAS.
+ *
+ * Requires SAS 9.4 M5 or later (PROC HTTP + libname JSON engine).
+ *
+ * ---------------------------------------------------------------------------
+ * TL;DR for SAS users:
+ *
+ *     %include 'run_jenner.sas';
+ *     %jenner_run(script=my_program.sas);              / * one script * /
+ *     %jenner_check_all();                             / * whole bundle dir * /
+ *
+ * ---------------------------------------------------------------------------
+ * What this file gives you:
+ *
+ *   %jenner_run         — POST one .sas file to the Jenner API, display the
+ *                         log + listing + any generated files.
+ *   %jenner_check_all   — walk every jenner-check/tNNN_* bundle,
+ *                         invoke the API for each, compare the response to
+ *                         the bundle's expected.json, produce a summary
+ *                         CSV + SAS dataset the repo owner can attach to the
+ *                         jenner-check PR.
+ *
+ * ---------------------------------------------------------------------------
+ * How the API call is built:
+ *
+ *   POST https://api.jenneranalytics.com/v1/run
+ *   Content-Type: multipart/form-data; boundary=...
+ *
+ *   fields:
+ *     script          the .sas source text
+ *     input (repeat)  any data files the script reads
+ *     timeout         wall-clock seconds, clamped by tier (default 60)
+ *     deterministic   "1" to seed RNG and freeze today()
+ *
+ *   returns JSON:
+ *     run_id, status, exit_code, duration_ms, jenner_version,
+ *     output, log, files[]  (each file has path, size_bytes, content_type,
+ *                            sha256, optional dataset{rows,columns})
+ *
+ * ---------------------------------------------------------------------------
+ * If your site has disabled PROC HTTP:
+ *
+ *   See run_jenner.bat (Windows) or run_jenner.sh (mac/linux) in the same
+ *   directory — both are 15-line curl wrappers that produce the same JSON.
+ *   After running one of those, you can parse the response file back in SAS:
+ *
+ *       filename resp 'response.json';
+ *       libname  resp JSON fileref=resp;
+ *       proc print data=resp.root; run;

+# run_jenner.sh - mac/linux runner for Jenner compatibility checks.
+#
+# Quick start:
+#   cd jenner-check/
+#   ./run_jenner.sh                  # lists bundles in the current dir
+#   ./run_jenner.sh t001_something   # run that one
+#   ./run_jenner.sh --all            # run every bundle in the current dir
+#
+# Usage:   ./run_jenner.sh [bundle-dir | script.sas | --all | --list] [response.json]
+#
+#   (no arg)     If the current directory has tNNN_* bundles, list them
+#                with a copy-paste command. Otherwise show this help.
+#
+#   --all        Run every tNNN_* bundle in the current directory in
+#                sequence, print a pass/fail summary.
+#
+#   --list, -l   List the bundles visible in the current directory and
+#                exit without running anything.
+#
+#   bundle-dir   A directory containing script.sas and (optionally)
+#                autoexec.sas. The two are concatenated (autoexec first,
+#                then a blank line, then script) and submitted together.
+#                This is the normal case.
+#
+#   script.sas   A single .sas file. Submitted as-is — no autoexec.
+#
+# The API response is written to <response.json> (or response.json in
+# the current directory if omitted) and the most useful fields are also
+# printed to stdout for a quick sanity check.
+#
+# Requires: bash 4+, curl. Both ship with every mainstream Linux distro
+# and macOS 12+. Windows: use run_jenner.bat (single-file mode) or WSL.

+# or `source ./...` will short-circuit error handling and can close your
+# terminal if an error path fires.
