feat(observability): optional self-hosted Sentry instrumentation for MCP workflow failures (Closes #606)

Add an env-var-gated, off-by-default Sentry SDK integration so MCP runtime
errors, fail-closed workflow blockers, lease/terminal-lock/stale-runtime
collisions, and recurring watchdog check-ins are visible in a self-hosted
Sentry at https://sentry.prgs.cc/. Gitea stays the source of truth; Sentry is
observe-only.

New module `sentry_observability.py` mirrors the `gitea_audit` conventions
(env-gated, best-effort, redacting):

- Config from MCP_SENTRY_ENABLED / SENTRY_DSN / SENTRY_ENVIRONMENT /
  SENTRY_RELEASE / MCP_SENTRY_TRACES_SAMPLE_RATE / MCP_SENTRY_ENABLE_LOGS.
  Active only when enabled AND a DSN is present; otherwise a hard no-op.
- Fail OPEN for observability (never blocks a tool success path) and fail
  CLOSED for redaction (drop a field rather than risk leaking it).
- `scrub_event` before_send/before_send_log hook + allowlisted tags: no
  tokens/passwords/keychain ids/DSNs/cookies, no raw session-state or full
  prompt bodies (session_id -> 12-char hash), no full filesystem paths
  (worktree path -> coarse category). Reuses incident_bridge + gitea_audit
  scrubbers.
- capture_exception, capture_workflow_blocker (with canonical next action),
  and monitor_checkin with six stable cron slugs (stale lease scan, terminal
  lock scan, allocator health, namespace health, dashboard freshness,
  reconciler cleanup).
- `sentry_sdk` is a lazily-imported optional dependency; the module imports
  and no-ops cleanly when the package is absent.

Wiring in gitea_mcp_server.py (additive, guarded, best-effort):
- init_sentry() in __main__ before mcp.run.
- capture_exception in the `_audited` failure path; capture_workflow_blocker
  in `_audit_pr_result` BLOCKED/FAILED path.
- allocator + namespace-health watchdog check-ins at their MCP tool sites
  (domain modules left pure).

Also: pin `sentry-sdk==2.20.0` (optional), document the six env vars in
`.env.example`, and add `docs/observability/sentry-integration.md` covering
project creation in https://sentry.prgs.cc/, DSN handling, local/dev/prod
config, redaction guarantees, and coexistence with the #612 incident bridge.

Tests: tests/test_sentry_observability.py (36 cases) cover disabled / enabled /
missing-DSN / missing-SDK, redaction, exception capture, workflow-blocker
capture, and cron check-in behaviour. Full suite: 2632 passed, 6 skipped.

-
-2. **Inspect the generated (or edited) profile** — confirm the reconciler
-   identity, for example:
-
-   ```bash

-   `gitea.pr.merge`, `gitea.pr.review`, `gitea.pr.create`,
-   `gitea.branch.push`, `gitea.repo.commit`.
-
-   No shorthand (`pr.close`, `issue.close`, `pr.comment`) may remain.
-   Validate with the production loader:
-
-   ```bash
-   python3 - <<'PY'

-   path = str(Path.home() / ".config/gitea-tools/profiles.json")

-   # Or assess the reconciler lists directly after extracting them:
-   # print(reconciler_profile.assess_reconciler_profile(allowed, forbidden))
-   PY
-   ```
-
-4. **Merging PR #688 (or any code PR) does not update the live profile.**
-   Code changes only the migration helper, schema, docs, and tests. The
-   operator must still run `migrate_profiles.py -w` or an equivalent
-   authorized edit of `~/.config/gitea-tools/profiles.json`.
-
-5. **Supported apply method:** `python3 migrate_profiles.py … -w` (backup
-   created automatically) **or** operator-authorized edit of the live
-   profiles file after backup. Unsupported: silent mtime tricks, manual
-   process kill to “reload”, or undocumented env overrides.
-
-6. **Backup and validation:** `-w` copies the input to
-   `<input_path>.bak` (or `--backup PATH`) before writing. Re-run
-   `load_config` / `assess_reconciler_profile` after write. Keep the
-   `.bak` until live whoami/capability checks pass.
-
-7. **Client-managed namespace reconnect/reload:** reconnect or reload the
-   IDE MCP client so `gitea-reconciler` restarts from current `master` and
-   the updated `GITEA_MCP_PROFILE=prgs-reconciler` config. Do not hand-launch
-   `mcp_server.py` / `gitea_mcp_server.py` with ad hoc `GITEA_*` env
-   (see #686 / #630).
-
-8. **Live reverification** (through the client-managed `gitea-reconciler`
-   namespace only):
-
-   - `gitea_whoami` → identity + profile `prgs-reconciler`
-   - `gitea_assess_master_parity` → `stale=false`, `restart_required=false`
-   - `gitea_resolve_task_capability(task="cleanup_merged_pr_branch")` →
-     `allowed_in_current_session=true` only when permission and role match
-   - `gitea_resolve_task_capability(task="delete_branch")` →
-     **not** allowed for reconciler (role denial must be enforced)
-
-9. **Guarded cleanup usage** (example for a merged PR whose source branch
-   remains on the remote):
-
-   ```text
-   gitea_cleanup_merged_pr_branch(
-     pr_number=<N>,
-     branch=<exact PR head branch>,
-     confirmation="CLEANUP MERGED PR <N> BRANCH <exact PR head branch>",

-     org="Scaled-Tech-Consulting",
-     repo="Gitea-Tools",
-     worktree_path="<path under branches/>",
-   )
-   ```
-
-   The tool refuses unmerged PRs, protected branches, preservation/evidence
-   branches, open-PR heads, mismatched branch names, and wrong confirmation.
-
-10. **Prohibitions**
-
-    - No raw `git push --delete`, `git branch -d` / `-D`, or delete refspecs
-    - No arbitrary `gitea_delete_branch` from reconciler
-    - No unsupported profile switching mid-run without full re-preflight
-    - No ad hoc hand-edits of live profiles **unless** operator-authorized,
-      backed up, and revalidated as above

+# Self-hosted Sentry observability for the Gitea MCP server (#606)
+
+Optional, **off-by-default** instrumentation that reports MCP runtime errors,
+fail-closed workflow blockers, lease / terminal-lock / stale-runtime
+collisions, and recurring watchdog check-ins to a **self-hosted** Sentry at
+`https://sentry.prgs.cc/`.
+
+> **Gitea remains the source of truth.** Sentry is observe-only. It never
+> approves, merges, closes, or otherwise mutates Gitea workflow state, and it
+> never bypasses leases, #332, workflow roles, or the MCP gates. Sentry alerts
+> may only feed the *sanctioned* Gitea issue/comment path via the #612 incident
+> bridge — never a direct write.
+
+Implemented by [`sentry_observability.py`](../../sentry_observability.py).
+
+---
+
+## 1. Create the Sentry project
+
+1. Sign in to the self-hosted Sentry at **`https://sentry.prgs.cc/`** (this is
+   **not** Sentry Cloud — do not use `*.ingest.sentry.io`).
+2. Create a new **Python** project named **`gitea-tools-mcp`**.
+3. Open **Settings → Projects → gitea-tools-mcp → Client Keys (DSN)** and copy
+   the DSN. It looks like `https://<publickey>@sentry.prgs.cc/<project-id>`.
+4. **Never commit the DSN.** It is a runtime secret supplied via env var only.
+
+## 2. Configure the environment
+
+All configuration is env-var driven (see [`.env.example`](../../.env.example)):
+
+| Variable | Purpose | Default |
+|----------|---------|---------|
+| `MCP_SENTRY_ENABLED` | Master gate (`1/true/yes/on`). Required. | off |
+| `SENTRY_DSN` | Self-hosted DSN. Required. | *(empty)* |
+| `SENTRY_ENVIRONMENT` | `local` / `dev` / `prod` tag. | `development` |
+| `SENTRY_RELEASE` | Release id (git SHA or version). | *(none)* |
+| `MCP_SENTRY_TRACES_SAMPLE_RATE` | Perf-trace sample rate `0.0–1.0` (clamped). | `0.0` |
+| `MCP_SENTRY_ENABLE_LOGS` | Forward Python logs as structured logs. | off |
+
+**The feature stays completely off unless `MCP_SENTRY_ENABLED` is truthy *and*
+`SENTRY_DSN` is non-empty.** With either missing, `init_sentry()` is a no-op,
+the SDK is never initialised, and no events are sent — existing tool behaviour
+and API-call patterns are unchanged.
+
+### Per-environment examples
+
+```bash
+# local (quiet: capture errors/blockers, no traces)
+export MCP_SENTRY_ENABLED=1
+export SENTRY_DSN="https://<key>@sentry.prgs.cc/<id>"
+export SENTRY_ENVIRONMENT=local
+
+# dev (light tracing + logs)
+export MCP_SENTRY_ENABLED=1
+export SENTRY_DSN="https://<key>@sentry.prgs.cc/<id>"
+export SENTRY_ENVIRONMENT=dev
+export MCP_SENTRY_TRACES_SAMPLE_RATE=0.2
+export MCP_SENTRY_ENABLE_LOGS=1
+
+# prod (errors/blockers + low-rate tracing, release-tagged)
+export MCP_SENTRY_ENABLED=1
+export SENTRY_DSN="https://<key>@sentry.prgs.cc/<id>"
+export SENTRY_ENVIRONMENT=prod
+export SENTRY_RELEASE="$(git rev-parse --short HEAD)"
+export MCP_SENTRY_TRACES_SAMPLE_RATE=0.05
+```
+
+The optional SDK is pinned in [`requirements.txt`](../../requirements.txt)
+(`sentry-sdk==2.20.0`). It is imported lazily: if the package is absent, the
+module still imports and every entry point is a safe no-op.
+
+## 3. What is instrumented
+
+| Signal | Where | Notes |
+|--------|-------|-------|
+| Startup init | `gitea_mcp_server.py` `__main__`, before `mcp.run` | Prints a redaction-safe status line to stderr. |
+| Failing mutations (exceptions) | `_audited(...)` context manager | `capture_exception` with scrubbed tags. |
+| Fail-closed blockers / failed mutations | `_audit_pr_result(...)` (BLOCKED/FAILED) | Structured `capture_workflow_blocker` event incl. the canonical next action when available (criterion 7). |
+| Allocator watchdog check-ins | `gitea_allocate_next_work` tool | `allocator_health`, `stale_lease_scan`, `terminal_lock_scan`. |
+| Namespace-health check-in | `gitea_assess_mcp_namespace_health` tool | `namespace_health`. |
+
+All capture paths are **best-effort / fail open**: a Sentry outage or capture
+error never breaks an MCP tool success path.
+
+## 4. Cron / watchdog monitors
+
+`sentry_observability.MONITOR_SLUGS` defines stable check-in slugs:
+
+| Registry key | Sentry monitor slug | Wired at |
+|--------------|--------------------|----------|
+| `stale_lease_scan` | `gitea-mcp-stale-lease-scan` | allocator run (global lease expiry) |
+| `terminal_lock_scan` | `gitea-mcp-terminal-lock-scan` | allocator run (terminal-lock lookup) |
+| `allocator_health` | `gitea-mcp-allocator-health` | allocator run |
+| `namespace_health` | `gitea-mcp-namespace-health` | namespace-health probe |
+| `dashboard_freshness` | `gitea-mcp-dashboard-freshness` | call `monitor_checkin("dashboard_freshness", ...)` from the dashboard refresh job (#605) |
+| `reconciler_cleanup` | `gitea-mcp-reconciler-cleanup` | call `monitor_checkin("reconciler_cleanup", ...)` from the reconciler cleanup entrypoint |
+
+Create matching Cron monitors in Sentry with those slugs. Emit an
+`in_progress` check-in at job start and `ok`/`error` at completion via
+`sentry_observability.monitor_checkin(slug_key, status)`.
+
+## 5. Redaction guarantees (fail closed)
+
+Redaction fails *closed*: if a field cannot be proven safe it is dropped rather
+than sent. The `before_send` (and `before_send_log`) hook `scrub_event`
+recursively redacts every outgoing event; on any error it drops the event
+entirely. Guarantees, proven by `tests/test_sentry_observability.py`:
+
+- **No** tokens, passwords, keychain IDs, DSNs, cookies, or `user:pass@host`.
+- **No** raw session-state or full prompt/comment bodies — `session_id` is only
+  ever surfaced as a 12-char `session_id_hash`.
+- **No** private config contents or raw credential headers.
+- **No** full local filesystem paths — a worktree path collapses to a coarse
+  `worktree_category` (`author` / `reviewer` / `merger` / `reconciler` /
+  `branches` / `root` / `other`).
+- Only the allowlisted tag keys in `ALLOWED_TAG_KEYS` are ever attached.
+
+## 6. Coexistence with GlitchTip / the #612 incident bridge
+
+This is the **outbound** path (MCP → Sentry SDK). It complements — it does not
+replace — the **inbound** [`incident_bridge.py`](../../incident_bridge.py)
+(#612), which turns Sentry/GlitchTip *observations* into durable Gitea issues
+and `incident_links` rows.
+
+- Prefer **one** observability path per environment. Point the MCP server's
+  `SENTRY_DSN` at the same self-hosted `gitea-tools-mcp` project that the #612
+  bridge reconciles from, so an MCP-reported error and its Gitea issue line up.
+- GlitchTip is Sentry-protocol compatible; if an existing GlitchTip DSN is in
+  use, either migrate it to `https://sentry.prgs.cc/` or document the split
+  (MCP → Sentry, legacy → GlitchTip) explicitly for operators.
+- The bridge remains the **only** sanctioned route from an alert back into
+  Gitea workflow state.
+
+## 7. Non-goals
+
+- Sentry must **not** become the workflow source of truth.
+- Sentry must **not** approve, merge, close, or mutate Gitea workflow state.
+- Sentry must **not** bypass leases, #332, workflow roles, or the MCP gates.

+"""Optional self-hosted Sentry observability for the Gitea MCP server (#606).
+
+Adds env-var-gated Sentry SDK instrumentation so runtime errors, fail-closed
+workflow blockers, lease/terminal-lock/stale-runtime collisions, and recurring
+watchdog check-ins are visible in a *self-hosted* Sentry at
+``https://sentry.prgs.cc/`` — never Sentry Cloud, and never as the workflow
+source of truth (Gitea stays canonical).
+
+Design constraints (mirror ``gitea_audit`` and the #612 incident bridge):
+
+- **Off by default.** With ``MCP_SENTRY_ENABLED`` false/unset *or* ``SENTRY_DSN``
+  empty, ``init_sentry`` is a no-op and no events are ever sent — existing tool
+  behaviour and API-call patterns are unchanged (acceptance criterion 1).
+- **Fail *open* for observability.** A Sentry outage, a missing ``sentry_sdk``
+  package, or any capture error must never break an MCP tool success path. Every
+  public entry point swallows its own exceptions.
+- **Fail *closed* for redaction.** If a field cannot be proven safe it is dropped
+  rather than sent. Tokens, passwords, keychain IDs, DSNs, private config, raw
+  session-state, full prompt bodies, and full filesystem paths never leave here.
+- **No hard dependency.** ``sentry_sdk`` is imported lazily; the module is fully
+  importable and testable without it installed.
+
+Sentry is observe-only: it must not approve, merge, close, or otherwise mutate
+Gitea workflow state, nor bypass leases, #332, or MCP gates. Alerts may only feed
+the sanctioned Gitea issue/comment path via the #612 incident bridge.

-1. Session locked to issue A blocks unrelated target issue B until B is selected.
-2. Diagnostic source edit on the root checkout is blocked.
-3. Same legitimate edit succeeds after issue ownership + isolated worktree bind.
-4. Running under pytest does not deactivate production guards when force-on.
-5. Dirty tracked Python files remain visible to porcelain consumers.
-6. Monkeypatching one helper cannot silently turn the full guard path into a no-op.
-7. Real mutation entrypoint proves production guards run before side effects.
-8. Same-issue edits in a valid isolated worktree remain unaffected.
-9. Blocker includes stable reason + exact recovery action.

-* continue out-of-scope source work while locked to a different issue;
