**Prompt writes (M1, unchanged):** Immutable registry rows via
`PRAutoBlogger_Prompt_Registry_Writer::create_version()`; only allowlisted prompt keys.
**M3 (v0.25.0 — assembled-instructions preview + version history/diff):**
A per-prompt Template/Preview toggle replaces the static editor header. The editable
"Template" view remains unchanged; the "Preview assembled instructions" tab is read-only
and shows the actual rendered text the LLM received (sourced from the last successful
`generation_log.request_json` for the stage, extracted via `Stage_Display_Map`). Falls
back to a sample render with `[token_name]` placeholders when no run exists yet. A
collapsible version history accordion beneath each editor lists all stored versions
(number, author, timestamp, active badge) with "Diff" buttons that compute and render
an LCS-based inline diff (added/removed/context/omitted lines, 3-line context window).
**M3 new files:** `ajax/class-pipeline-preview-handler.php`,
`ajax/class-pipeline-history-handler.php`, `admin/class-pipeline-preview-source.php`.
**Security (M3):** All three new AJAX actions require `manage_options` + nonce. Prompt
keys validated against `Step_Map::allowed_prompt_keys()`. Preview returned as `esc_html`
server-side; diff text inserted via `textContent` (not innerHTML) in JS.

## [0.25.0] - 2026-06-23
### Added
- **Pipeline Settings M3 — assembled-instructions preview + prompt version history/diff:**
Per-prompt Template/Preview toggle and version history accordion in the Pipeline Settings page.
- **Template / Preview toggle (per prompt):** A segmented button pair sits above every
prompt editor. "Template" (default) shows the editable textarea with the note "Editing the
template affects all future runs." "Preview assembled instructions" (read-only) fetches and
shows the fully-rendered instruction text the LLM actually received, with all tokens filled.
The two states are mutually exclusive; the preview pane has no save path server-side or
client-side — CPO guardrail enforced at both layers.
- **Preview source (last-run preferred, sample fallback):** `PRAutoBlogger_Pipeline_Preview_Source`
queries `prab_generation_log` for the most recent successful row whose stage maps to the
prompt key via `Stage_Display_Map::all()` (stage-list-driven — Phase 2b stages resolve
automatically). Extracts the rendered message content from `request_json` (system-role
content for `*.system` keys; user-role content for agent keys). When no run exists yet,
renders the active template with `[token_name]` placeholders so the admin sees the token
injection map before any article has been generated. Clearly labelled in the UI
("Tokens from last run · <date>" vs. "Sample render — no run found yet").
- **Version history accordion (per prompt):** Collapsible list below the editor showing
every stored version (version number, author, created_at, active badge). Read-only;
never mutates the registry. The "Diff" button computes and shows an inline line-level diff
between adjacent versions (v(N-1) → vN) using a pure-PHP LCS implementation with a
3-line context window and `omitted: N lines unchanged` collapse for distant context.
Diff text is rendered by type (added/removed/context/omitted) with colour coding matching
the designer mockup. All diff output is `esc_html`'d server-side and inserted via
`textContent` in JS (double-escaped path).
- **New AJAX endpoints (both `manage_options` + nonce gated):**
- `prautoblogger_pipeline_preview` — returns rendered preview text (from last run or
sample); no save path; server-side read-only contract.
- `prautoblogger_pipeline_history` — returns version list for a key.
- `prautoblogger_pipeline_diff` — returns LCS diff between two versions.
All endpoints validate the prompt key against `Step_Map::allowed_prompt_keys()` (the
same allowlist the save handler uses) before any DB access.
- **Stage-list-driven throughout:** all preview/history/diff logic goes through
`Stage_Display_Map::all()` and `Step_Map::allowed_prompt_keys()`; no hard-coded stage
names — Phase 2b `curate`/`seo` stages will work without rework.
### New Files
- `includes/ajax/class-pipeline-preview-handler.php` — Preview AJAX endpoint.
- `includes/ajax/class-pipeline-history-handler.php` — History + diff AJAX endpoint.
- `includes/admin/class-pipeline-preview-source.php` — Last-run / sample render logic.
- `tests/unit/Ajax/PipelineHistoryHandlerTest.php` — Tests for diff algorithm + slug resolution.
- `tests/unit/Ajax/PipelinePreviewSourceTest.php` — Tests for message extraction + stage mapping.
### Changed
- `includes/admin/class-pipeline-settings-renderer.php` — M3: passes `preview_nonce`,
`history_nonce`, `diff_nonce`, action names, and `panel.versions` list to the template;
`build_prompt_panel_data()` now includes the full `versions` array for server-side
history rendering.
- `includes/admin/class-pipeline-settings-page.php` — M3: localizes `prabPipeline` JS
object with AJAX actions + nonces; no menu changes.
- `templates/admin/pipeline-settings-prompt-panel.php` — Redesigned: added Template/Preview
toggle (`pab-tp-toggle`), preview block with read-only badge + source note,
version history accordion with Diff buttons, and inline diff panel.
- `templates/admin/pipeline-settings-page.php` — Passes full `$view` to the prompt panel
partial (required for nonce data-attributes).
- `assets/js/pipeline-settings.js` — M3: toggle logic, preview AJAX fetch, history
accordion expand/collapse, diff AJAX fetch + render, diff close.
- `assets/css/pipeline-settings.css` — M3: styles for tp-toggle, preview block,
history accordion, diff panel (appended; all existing styles preserved).
- `includes/class-prautoblogger.php` — Registers `Pipeline_Preview_Handler` and
`Pipeline_History_Handler` hooks in `register_ajax_hooks()`.
### Tests
- `PipelineHistoryHandlerTest`: covers `compute_diff()` (change detection, identical texts,
line shape, omitted-context collapse) and `resolve_key_from_slug()` round-trip.
Brace count: 12/12.
- `PipelinePreviewSourceTest`: covers `extract_rendered_from_messages()` (system vs user role
preference, longest fallback, empty input) and `stage_for_key()` (known + unknown keys).
Brace count: 8/8. All methods use reflection on private statics — no `Functions\when()`
on `Class::method` (DoD invariant preserved).
### Fixed
- `PipelinePreviewSourceTest::test_stage_for_key_maps_research_system`: corrected expected
value from `'research'` to `'llm_research'`. The production `stage_for_key('research.system')`
returns `'llm_research'` because `Stage_Display_Map::MAP` lists `llm_research` before the
Phase 2b `research` entry (both share `prompt_key => 'research.system'`; first match wins).
The real `prab_generation_log.stage` value written by `LLM_Research_Provider::collect_data()`
is `'llm_research'` — confirmed in `includes/providers/class-llm-research-provider.php` line 74.
The mapping was correct; the test assertion was wrong.

/**
* Pipeline Settings page — step rail and prompt editor interactions.
* Pipeline Settings page — M3: Template/Preview toggle, version history accordion,
* and inline diff panel.
*
* Responsibilities:
* - Confirm before resetting a prompt to default (redundant safety; the
* PHP onclick already handles it, but JS enhances UX).
* M3 Responsibilities:
* 1. Template / Preview toggle per prompt panel:
* - "Template" tab: shows the editable textarea (default).
* - "Preview assembled instructions" tab: fetches via AJAX and shows the
* fully-rendered prompt text. Read-only; no save path exists in JS or PHP.
* The two states are mutually exclusive; pressing "Template" never sends
* any network request.
* 2. Version history accordion: toggle show/hide per prompt key.
* 3. Inline diff panel: on "Diff" button click, fetch the computed diff from
* the server and render added/removed/context lines with colour coding.
* "Close diff" hides the panel.
*
* Note: model selection is handled entirely by model-picker.js, which writes
* the chosen model id directly to the hidden input named after the option
* (e.g. name="prautoblogger_research_model"). No event bridge is needed here —
* the form submits that value on the standard POST to handle_model_save().
* Security notes:
* - Preview and diff bodies are returned pre-escaped (esc_html'd) by PHP.
* They are inserted via .text() / textContent, never innerHTML, so no
* XSS vector exists even if the server escaping were to fail.
* - Nonces come from the prabPipeline JS object (localized in enqueue_assets).
*
* @see admin/class-pipeline-settings-save-handler.php — Reads $_POST[$option_name].
* @see assets/js/model-picker.js — Writes to the hidden input by DOM id.
* Note: model selection is handled entirely by model-picker.js; no bridge needed.
*
* @see admin/class-pipeline-settings-page.php -- Localizes prabPipeline.
* @see ajax/class-pipeline-preview-handler.php -- Preview AJAX endpoint.

* Resolves the "assembled instructions" preview body for a prompt key.
*
* What: Two strategies, tried in order:
*
* 1. Last-run strategy: Queries generation_log for the most recent
* successful row whose stage maps to the given prompt_key via
* Stage_Display_Map. Decodes the stored request_json and extracts
* the user-role message content (the fully-rendered, token-filled
* instruction the LLM actually received). This is the preferred
* source because it is factually what ran.
*
* 2. Sample render: Falls back to Prompt_Registry::render() with
* placeholder token values taken from the registry def. Tokens are
* replaced with "[sample: <token_name>]" labels so the admin can
* see the template's token slots without live data. Labelled
* "sample — no run found" in the UI.
*
* Neither path has a save route. All returned text is plain strings;
* escaping is the caller's responsibility (Pipeline_Preview_Handler
* calls esc_html before JSON-encoding).
*
* Stage-list-driven: Stage_Display_Map::all() iterates the full known
* stage vocabulary; Phase 2b stages resolve automatically.
*
* Who calls it: PRAutoBlogger_Pipeline_Preview_Handler::handle().
* Dependencies: WordPress $wpdb, PRAutoBlogger_Stage_Display_Map,
* PRAutoBlogger_Prompt_Registry.

*
* What: Returns the fully-assembled instruction text for a given prompt key
* and stage. Prefers the last run's rendered prompt (extracted from
* the generation_log request_json) so the admin sees the exact text
* the LLM received; falls back to a sample render (template with
* placeholder token values) when no run exists yet. The preview is
* ALWAYS read-only — there is no save path, cap check, or nonce that
* would allow the returned text to be persisted. Escaping is done
* server-side; the client renders as pre-formatted text.
*
* Stage-list-driven: the prompt_key -> stage mapping goes through
* Stage_Display_Map so Phase 2b stages auto-resolve without rework.
*
* Security: cap check (manage_options) + nonce verification on every
* request. Output is JSON with esc_html'd preview body + a
* boolean indicating whether the source was a real run.
*
* Who triggers it: pipeline-settings.js fetch() on "Preview" tab click.
* Dependencies: PRAutoBlogger_Prompt_Registry (render / get_active),
* PRAutoBlogger_Pipeline_Preview_Source (last-run query),
* PRAutoBlogger_Pipeline_Settings_Step_Map (key allowlist),
* PRAutoBlogger_Stage_Display_Map (stage vocabulary).
