From 41831677ff0b234659292cd3d2ab32615f160c90 Mon Sep 17 00:00:00 2001 From: Dhruva Reddy Date: Fri, 1 May 2026 12:47:18 -0700 Subject: [PATCH] feat: drift detection on push (--overwrite to bypass) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Problem.** Today: you pull, your teammate edits the same assistant on the dashboard during a live test, you push your unrelated branch, and their dashboard edit disappears with no warning. Customer-success reps update business hours via the dashboard; the next gitops push silently reverts them. Even `git revert + push` rollbacks have the same problem — they overwrite whatever's currently live, not just the change being reverted. The engine had no way to detect this because the state file only stored name→UUID, no record of the platform's content at last pull. **What this fix does.** Now that Stack F populates `lastPulledHash`, drift detection becomes possible. Before each PATCH, the engine GETs the current platform payload, hashes it, and compares to the `lastPulledHash` in state. - Hashes match → continue silently. - Hashes differ + no flag → **refuse the push**, point at the drift, ask the operator to either pull-and-resolve or pass `--overwrite` to take ownership. - Hashes differ + `--overwrite` → log "overwriting drift" and proceed. - No baseline (legacy state, first push after Stack F) → log "drift unknown — proceeding" and don't block. Also adds a specific helper for the **Cartesia voice picker** footgun: if `pronunciationDictId` was set at last pull but isn't on the platform now, surface that explicitly so the operator notices. **Outcome you'll notice.** Concurrent dashboard edits no longer disappear silently. If someone else touched a resource between your pull and your push, you see the conflict at push time and have to make an explicit call (overwrite, or pull and resolve). The engine becomes a real safety rail rather than a blind PATCH machine. --- Before each PATCH, GET the current platform payload, hash it, and compare to the lastPulledHash recorded in state (Stack F). If the hashes differ, the dashboard has drifted away from the version we last pulled — refuse to push without --overwrite. Behavior matrix: - No lastPulledHash (legacy state, first push after Stack F): log "drift unknown — proceeding" and continue. Don't block. - Hashes match: continue silently. - Hashes differ + no --overwrite: refuse the push, return null. - Hashes differ + --overwrite: log "overwriting drift" and continue. Files: - src/drift.ts (NEW): checkDriftForUpdate(endpoint, state, overwrite). GETs platform, strips server-managed fields (id/orgId/createdAt/etc) to align hash basis with cleanResource()'s output, sha256 compares. Returns DriftCheckResult with reason and message for caller logging. - src/state-serialize.ts: checkPronunciationDictDrop helper for the Cartesia voice-picker case (improvements.md #7) — pure data, safe to import in tests. - src/config.ts: --overwrite flag. - src/push.ts: drift gate in upsertResourceWithStateRecovery before every PATCH. Skipped in dry-run (operator wants to see what would happen). Skipped if no baseline. - tests/drift.test.ts: hash-match → ok, hash-differ-no-overwrite → ok=false, hash-differ-overwrite → ok=true, no-baseline → ok=true. Closes improvements.md #1, #7. Partial #2 (push side caught; pull side same-file conflict still requires manual resolution). 🤖 Generated with [Claude Code](https://claude.com/claude-code) --- ## Update — 11labs `pronunciationDictionaryLocators` array also covered `checkPronunciationDictDrop` now detects drops in both pronunciation- dictionary shapes Vapi exposes: - **11labs** (the documented shape): `voice.pronunciationDictionaryLocators[]` — array of `{ pronunciationDictionaryId, versionId }`. We warn on N → M shrinks (M < N) including N → 0 and array-going-missing. - **Cartesia** (passthrough — not in Vapi docs but observed): `voice.pronunciationDictId` — single string id. Existing 1 → 0 detection unchanged. Reference: https://docs.vapi.ai/assistants/pronunciation-dictionaries Six new test cases pin the 11labs behavior: array clear (1 → 0), shrink (2 → 1), array-going-missing entirely, no-op when unchanged, no-op when locators are added (additive growth shouldn't warn), and the defensive hybrid case where a payload carries both shapes. --- improvements.md | 6 +- src/config.ts | 7 +- src/drift.ts | 134 ++++++++++++++++++++++++++++++++++++++ src/push.ts | 34 ++++++++++ src/state-serialize.ts | 65 +++++++++++++++++++ tests/drift.test.ts | 142 +++++++++++++++++++++++++++++++++++++++++ 6 files changed, 384 insertions(+), 4 deletions(-) create mode 100644 src/drift.ts create mode 100644 tests/drift.test.ts diff --git a/improvements.md b/improvements.md index 220bb24..2df5c8e 100644 --- a/improvements.md +++ b/improvements.md @@ -52,13 +52,13 @@ you which stack PR closes the row.** | # | Title | Why it matters | Depends on | Status | | --- | -------------------------------------------------------- | -------------------------------------------------- | ---------- | --------------------------------- | -| 1 | `push` drift detection | Prevent silent overwrites of dashboard edits | #4 | Open (Stack G planned) | -| 2 | `apply` same-file conflict | `apply` drops concurrent same-file dashboard edits | #4 | Open (Stack G planned) | +| 1 | `push` drift detection | Prevent silent overwrites of dashboard edits | #4 | RESOLVED 2026-04-30 (Stack G) | +| 2 | `apply` same-file conflict | `apply` drops concurrent same-file dashboard edits | #4 | Partial — Stack G GET on push | | 3 | Rollback | Current undo can clobber newer live changes | #4, #5 | Open (Stack H planned) | | 4 | State schema content hashes | Architectural unlock for #1, #2, #3, #6, #7 | None | RESOLVED 2026-04-30 (Stack F) | | 5 | `push --dry-run` | Cheapest operator-safety win | None | RESOLVED 2026-04-30 (Stack C) | | 6 | API-level optimistic concurrency | Server-side conflict rejection | Platform | Deferred (Stack I, gated) | -| 7 | Voice edits drop pronunciation-dictionary attachments | Silent regression on Cartesia + 11labs voice edits | #4 | Open (Stack G planned) | +| 7 | Voice edits drop pronunciation-dictionary attachments | Silent regression on Cartesia + 11labs voice edits | #4 | RESOLVED 2026-04-30 (Stack G) | | 8 | Dashboard prompt edits can in-place duplicate the prompt | Two stacked prompt versions = stitched output | None | Partial — Stack D heuristic | | 9 | Provider-specific voice schema mismatch (push 400) | `voice.speed` vs `voice.generationConfig.speed` | None | RESOLVED 2026-04-30 (Stack D + A) | | 10 | Targeted assistant push mints duplicate tools | Re-pushing assistant duplicates `end-call-*` tools | #4 | Partial | diff --git a/src/config.ts b/src/config.ts index 6288c4a..b20eddd 100644 --- a/src/config.ts +++ b/src/config.ts @@ -87,6 +87,7 @@ function parseFlags(): { bootstrapSync: boolean; dryRun: boolean; strictValidation: boolean; + overwriteDrift: boolean; applyFilter: ApplyFilter; } { const args = process.argv.slice(3); @@ -95,12 +96,14 @@ function parseFlags(): { bootstrapSync: boolean; dryRun: boolean; strictValidation: boolean; + overwriteDrift: boolean; applyFilter: ApplyFilter; } = { forceDelete: args.includes("--force"), bootstrapSync: args.includes("--bootstrap"), dryRun: args.includes("--dry-run"), strictValidation: args.includes("--strict"), + overwriteDrift: args.includes("--overwrite"), applyFilter: {}, }; @@ -115,7 +118,8 @@ function parseFlags(): { arg === "--force" || arg === "--bootstrap" || arg === "--dry-run" || - arg === "--strict" + arg === "--strict" || + arg === "--overwrite" ) continue; @@ -252,6 +256,7 @@ export const { bootstrapSync: BOOTSTRAP_SYNC, dryRun: DRY_RUN, strictValidation: STRICT_VALIDATION, + overwriteDrift: OVERWRITE_DRIFT, applyFilter: APPLY_FILTER, } = parseFlags(); diff --git a/src/drift.ts b/src/drift.ts new file mode 100644 index 0000000..53f88e5 --- /dev/null +++ b/src/drift.ts @@ -0,0 +1,134 @@ +// ───────────────────────────────────────────────────────────────────────────── +// Drift detection — Stack G +// +// Before each PATCH, GET the current platform payload, hash it, and compare +// to the `lastPulledHash` recorded in state.
