[CONTENT SPRINT] One ESC Environment, Many Secret Stores

[sicarul]

Why this content is interesting

• It reflects how secrets actually live across several stores in mature environments.
• It is scheduled for 2026-07-02 as part of the content sprint's two-post-per-week cadence.

What we took into account

• We considered AWS Secrets Manager, HashiCorp Vault, 1Password, conflict naming, and a single consumer interface.
• We avoided unsupported customer claims, certification guarantees, and obsolete product naming.
• We kept the metadata and social copy curated around the post's concrete reader outcome.

Why it is useful to an end user

• End users get a model for composing multiple secret sources into one resolved ESC environment.
• The post is written to help practitioners recognize the problem, understand why it matters, and leave with an actionable Pulumi workflow.

Design need

• This PR is labeled needs-design because the post needs a final meta image before publication.
• Existing feature.png and meta.png files are placeholders unless Design chooses to reuse or adapt them.

Metadata

• Title: One ESC Environment, Many Secret Stores
• Meta description: Compose Pulumi ESC environments from AWS Secrets Manager, HashiCorp Vault, and 1Password so apps consume one resolved configuration view.

Suggestions (advisory)

These are stylistic notes — they don't block the post.

X

• Missing pointer — the post just ends; add a line that signals there's more in the article
• Second line delivers the mechanism outright ("compose...into one resolved environment") — withhold the approach so the reader still has a reason to click

LinkedIn

• Opening "Most teams inherit multiple secret stores" is generic — lead with a concrete tension (e.g., different credentials per environment, or a Friday-night rotation incident)
• Second paragraph closes the curiosity gap completely — "This guide shows how Pulumi ESC can compose..." tells the reader the full answer; withhold the mechanism and add a pointer instead

Bluesky

• Missing pointer — the post just ends; add a line that signals there's more in the article
• Second line states the mechanism outright ("compose...into one resolved config view") — withhold the approach to create tension

Docs review for PR 18957

Reviewing as a CI agent. Two distinct problems: a sizable stack of unrelated agent artifacts that shouldn`t ship in this PR, and some style/structure issues in the blog post itself.

Out-of-scope files (blocker)

This PR is titled "One ESC Environment, Many Secret Stores" but ~95% of the diff has nothing to do with that post. Please drop the following before merging — they look like local Sisyphus/agent planning artifacts and a raw research dump that escaped a worktrees/ setup:

• .sisyphus/boulder.json, .sisyphus/evidence/*, .sisyphus/notepads/*, .sisyphus/plans/customer-blog-posts.md, .sisyphus/run-continuation/* — agent state, not project content.
• new_content.md (repo root) — the Platybot customer-signal analysis. Useful as a working doc, but doesnt belong at the root of pulumi/docs`. The plan itself even instructs "do NOT push a PR" for this exploratory work.

If you want to keep this scaffolding locally, the plans own foundation step adds worktrees/to.git/info/exclude— consider doing the same for.sisyphus/andnew_content.md` so they stop following you into PRs.

Blog post: content/blog/multi-source-secrets-with-pulumi-esc/index.md

1. Placeholder meta and feature images (blocker). meta.png and feature.png are byte-identical (verified via md5) to .claude/commands/_common/images/blog-post-meta-placeholder.png and blog-post-feature-placeholder.png. The PR body acknowledges this with the needs-design label, so flagging only to confirm: this can`t publish until Design lands real assets.

2. Duplicate content across the more-break. Line 25 opens "The pain of secret sprawl" with "As organizations grow, secrets naturally scatter across different platforms." Line 39 then opens "The Challenge of Secret Sprawl" with the same sentence verbatim and re-covers identical material as a list. Pick one — the list version on line 39–44 is tighter; the prose version on line 25 can be cut entirely. The intro on line 19–21 is sufficient hook on its own.

3. More-tag placement is too deep (line 35). The criteria call for the break after 1–3 paragraphs. Right now four sections (intro, The pain of secret sprawl, Why it matters now, Reader outcome) sit above the fold. Once the duplicate "The pain of secret sprawl" is removed, move the more-tag up to right after the intro on line 21, before the first H2.

4. H2 heading case (STYLE-GUIDE.md — H2+ is sentence case). Four headings are Title Case and should be lowercased to sentence case:

• Line 37: The Challenge of Secret Sprawl → The challenge of secret sprawl
• Line 48: Composing a Multi-Source Environment → Composing a multi-source environment
• Line 104: Namespacing and Precedence → Namespacing and precedence
• Line 110: Consuming the Resolved View → Consuming the resolved view

The first three H2s (lines 23, 27, 31) are correctly sentence-cased — these four are the outliers.

5. Missing first-mention links. Per blog criteria, every tool/product gets hyperlinked on first mention. None of these are linked anywhere in the post:

• Line 19: AWS Secrets Manager, HashiCorp Vault, 1Password
• Line 114: Pulumi CLI

/docs/esc/ is the only link in the post (line 33).

6. Weak ending; no CTA shortcode. Line 122 wraps with a generic summary. Feature/integration posts should land with a concrete next step using the blog/cta-button shortcode pointing at the most relevant doc (e.g. /docs/esc/integrations/dynamic-secrets/ or the AWS/Vault/1Password integration pages directly).

7. Vault snippet worth confirming. Line 79–82 reads ${vault.secrets.stripe-key.data.key}. The narration on line 102 says this refers to "the key field stored at secret/data/stripe". For the Vault KV v2 engine, the data wrapper is part of the API path (secret/data/...) — the returned value from fn::open::vault-secrets is whats stored under that paths data object. Whether you need .data.key or just .key depends on the engine version and whether ESC unwraps it. Worth verifying against a working environment before publish; if KV v2 is implied, calling that out explicitly will help readers.

8. ESC YAML otherwise checks out. I cross-referenced the fn::open::aws-secrets, fn::open::vault-login/vault-secrets, and fn::open::1password-secrets blocks against content/docs/esc/integrations/dynamic-secrets/*.md and the syntax matches.

9. Minor AI/hedging language. A few phrases lean generic — "naturally scatter", "best-of-breed", "improve your security posture". Easy to tighten in a pass after the structural changes above.

Publishing readiness checklist

• social: block present with twitter / linkedin / bluesky copy
• meta_image set but is the placeholder (verified via md5)
• meta_image uses current Pulumi logos — N/A until real asset
• More-tag present but placement too deep
• Author profile exists (data/team/team/pablo-seibelt.toml) with avatar (static/images/team/pablo-seibelt.jpg)
• All links resolve (only /docs/esc/)
• Code examples correct, language specifiers present
• No animated GIFs used as meta_image
• Title ≤60 chars (36)

meta_desc length is 137 chars — within the 50–160 window.

Re-review for PR 18957 (commit f1a46b1)

Branch cleanup confirmed: git diff HEAD~1..HEAD --stat shows only the three intended files (index.md, feature.png, meta.png). The .sisyphus/ and new_content.md artifacts from the prior diff are gone. Single clean commit on top of current origin/master (a853d02). Nice scoping.

What's addressed since last review

• Out-of-scope files removed. Diff is now scoped to the blog post only.
• Duplicate "The pain of secret sprawl" prose section removed. The intro flows straight into "Why it matters now" without retreading the same ground.
• Social frontmatter formatting fixed. Each of twitter, linkedin, bluesky now has the required paragraph break — matches the bot's earlier suggested copy verbatim. The 2026-05-13 20:50 social-media-review FAIL should clear on its next run.

Still applies to this post

A handful of the prior items weren't addressed and still apply to this PR (not blockers, but worth picking up before publish):

1. H2 heading case — STYLE-GUIDE violation (AGENTS.md: "H2+ = Sentence case"). Four headings remain Title Case:

• Line 42: The Challenge of Secret Sprawl → The challenge of secret sprawl
• Line 53: Composing a Multi-Source Environment → Composing a multi-source environment
• Line 109: Namespacing and Precedence → Namespacing and precedence
• Line 115: Consuming the Resolved View → Consuming the resolved view

The first three H2s (lines 32, 36, and the removed-duplicate-replacement) are correctly sentence-cased, so the rule is being applied — just inconsistently. Fix this →

2. First-mention links still missing. Per blog criteria, every product/tool gets a link on first mention. /docs/esc/ on line 38 remains the only outbound link. Suggested targets:

• Line 28 — AWS Secrets Manager → /docs/esc/integrations/dynamic-secrets/aws-secrets/
• Line 28 — HashiCorp Vault → /docs/esc/integrations/dynamic-secrets/vault-secrets/
• Line 28 — 1Password → /docs/esc/integrations/dynamic-secrets/1password-secrets/
• Line 119 — Pulumi CLI → /docs/install/

All four target files exist (verified content/docs/esc/integrations/dynamic-secrets/).

3. No CTA shortcode at the end. Line 127 still closes with a generic "reduce complexity and improve your security posture" summary. Feature/integration posts conventionally close with the blog/cta-button shortcode — a natural target here is /docs/esc/integrations/dynamic-secrets/ (the integrations landing page) or /docs/esc/get-started/.

4. Vault .data.key reference (line 103, 107) — worth double-checking before publish. Cross-referenced against content/docs/esc/integrations/dynamic-secrets/vault-secrets.md:

• The official docs example uses path: api-key (no secret/data/ prefix), and the rendered output shows vault.secrets.<name>.data.<field> — so .data.key is consistent with how ESC wraps the response.
• However, the post uses path: secret/data/stripe (the KV v2 raw API path). That's a different convention than the docs example. Worth confirming whether ESC expects the KV v2 logical path (secret/stripe) or the raw API path (secret/data/stripe) — and whether the .data wrapper is double-applied in the latter case.

If KV v2 is what you're modeling here, calling that out in the prose ("for KV v2 mounts, the data/ segment in the path is required, and the returned value lives under .data") will save readers a debugging round.

5. More-tag placement — minor. After removing the duplicate section, the break (line 40) now sits below intro + "Why it matters now" + "Reader outcome" — three small sections / four paragraphs above the fold. The criteria suggest 1–3 paragraphs. Reasonable judgment call either way; flagging only as a soft note. If you want it tighter, moving it to right after line 30 (before ## Why it matters now) would be conventional.

6. AI/hedging phrasing — soft. Three phrases stand out as generic and easy to tighten in a polish pass: "naturally scatter" (line 44), "best-of-breed" (line 34), "improve your security posture" (line 127). Not a blocker; just opportunities.

Acknowledged in PR body — confirming status

• Placeholder images. feature.png and meta.png are still byte-identical to .claude/commands/_common/images/blog-post-feature-placeholder.png and blog-post-meta-placeholder.png (verified via md5). The needs-design label on the PR already covers this — not asking you to fix, just confirming for the record that real assets are still pending before publish on 2026-07-02.

Updated publishing checklist

• social: block present, paragraph formatting now compliant
• Diff scoped to blog files only
• Author profile exists (data/team/team/pablo-seibelt.toml) with avatar
• Code examples have language specifiers, ESC YAML cross-checks against docs
• Title ≤60 chars (36)
• meta_desc length 137 chars (within 50–160)
• meta_image is the placeholder — pending Design (acknowledged)
• H2 heading case (4 headings)
• First-mention links (4 missing)
• CTA shortcode at the end
• Confirm Vault path/.data convention
• More-tag placement (minor, judgment call)

---

The rewrite genuinely cleaned up the structural mess and the social-copy fix is exactly right. The remaining items are concentrated in style-guide adherence (H2 case), first-mention links, and the ending CTA — all small mechanical edits.

@sicarul — mention me again if you'd like a final pass after those, or want me to make the H2-case and link edits directly.

Re-review for PR 18957 (commit f1a46b1)

Heads up — the branch is on the same commit (f1a46b1a35619f1c6a6a706a2e8450b9795f6faf) I reviewed in my prior pass. Nothing new has been pushed since 21:55 UTC, so the file is byte-identical to what was already reviewed. If you intended to push changes addressing the content feedback, they didn't make it to the remote — git push may have failed silently, or the work may still be local/uncommitted.

• Verify branch state and PR scope
• Read current index.md
• Check H2 heading case
• Check first-mention links
• Check for CTA shortcode
• Verify placeholder images
• Cross-check Vault path/.data reference
• Confirm more-tag placement

Confirmed: what's already in good shape

• Diff scope is clean — git diff HEAD~1..HEAD --stat shows only the three intended files (index.md, feature.png, meta.png). The earlier .sisyphus/ / new_content.md cleanup is holding.
• Social frontmatter paragraph formatting is correct (each of twitter, linkedin, bluesky has the required blank line).
• Duplicate "The pain of secret sprawl" prose section is gone — intro flows into "Why it matters now" cleanly.
• Single clean commit on top of recent origin/master.

Still outstanding (unchanged from prior review)

These items from the 21:55 UTC review still apply verbatim — the file hasn't been edited:

1. H2 heading case (AGENTS.md: "H2+ = Sentence case"). Four headings remain Title Case:

• Line 42: The Challenge of Secret Sprawl → The challenge of secret sprawl
• Line 53: Composing a Multi-Source Environment → Composing a multi-source environment
• Line 109: Namespacing and Precedence → Namespacing and precedence
• Line 115: Consuming the Resolved View → Consuming the resolved view

Fix this →

2. First-mention links still missing. /docs/esc/ on line 38 is the only outbound link. Verified targets exist:

• Line 28 — AWS Secrets Manager → /docs/esc/integrations/dynamic-secrets/aws-secrets/
• Line 28 — HashiCorp Vault → /docs/esc/integrations/dynamic-secrets/vault-secrets/
• Line 28 — 1Password → /docs/esc/integrations/dynamic-secrets/1password-secrets/
• Line 119 — Pulumi CLI → /docs/install/

3. No CTA shortcode at the end. Line 127 still closes with "reduce complexity and improve your security posture." Feature/integration posts conventionally close with the blog/cta-button shortcode — natural target is /docs/esc/integrations/dynamic-secrets/ or /docs/esc/get-started/.

4. Vault .data.key (lines 103, 107) — worth confirming. The post uses path: secret/data/stripe (KV v2 raw API path), then ${vault.secrets.stripe-key.data.key}. The official docs example at content/docs/esc/integrations/dynamic-secrets/vault-secrets.md uses path: api-key (logical path) with .data.<field>. Either confirm both conventions work with this .data access pattern, or switch to the canonical path: secret/stripe form and call out in prose that the .data wrapper is the KV v2 response shape.

5. More-tag placement (minor). Break at line 40 sits below intro + "Why it matters now" + "Reader outcome" (criteria suggest 1–3 paragraphs). Judgment call — moving the break to right after line 30 would tighten it.

6. AI/hedging phrasing (soft). "naturally scatter" (line 44), "best-of-breed" (line 34), "improve your security posture" (line 127).

Acknowledged (pending Design)

• feature.png and meta.png confirmed byte-identical to .claude/commands/_common/images/blog-post-{feature,meta}-placeholder.png. Covered by the needs-design label — flagging for the record only.

Updated checklist

4. Vault .data.key reference (lines 87, 103, 107) — worth confirming. The post uses path: secret/data/stripe (KV v2 raw API path) and ${vault.secrets.stripe-key.data.key}. The canonical ESC docs example at content/docs/esc/integrations/dynamic-secrets/vault-secrets.md (lines 28–35) uses path: api-key (logical path) and the rendered output shows vault.secrets.<name>.data.<field>. Two reasonable resolutions:

• Switch to the canonical form: path: secret/stripe (or path: stripe, depending on mount) and keep ${vault.secrets.stripe-key.data.key} — and add a one-line explanation that .data is the KV v2 response wrapper.
• Keep path: secret/data/stripe and confirm in a working environment that .data.key still resolves (the raw API path may or may not be double-wrapped).

Either way, calling out KV v2 explicitly in the prose around line 107 will help readers who are debugging.

5. More-tag placement (minor). Break at line 40 sits below intro + "Why it matters now" + "Reader outcome" (criteria suggest 1–3 paragraphs). Judgment call.

6. AI/hedging phrasing (soft). "naturally scatter" (line 44), "best-of-breed" (line 34), "improve your security posture" (line 127).

Re-review for PR 18957 (commit f1a46b1)

• Verify branch state and PR scope
• Read current index.md
• Check whether content-feedback items were addressed
• Note draft/needs-design status change

HEAD is still f1a46b1a35619f1c6a6a706a2e8450b9795f6faf — the same commit reviewed at 21:55, 22:32, and 22:35 UTC. content/blog/multi-source-secrets-with-pulumi-esc/index.md is byte-identical to those passes; feature.png / meta.png md5s still match the placeholders. No new push has landed since 21:55 UTC.

Status change acknowledged

• PR is now draft — appropriate given the open content items below and the pending Design assets.
• needs-design label removed — flagging because the meta/feature PNGs are still byte-identical to .claude/commands/_common/images/blog-post-{feature,meta}-placeholder.png (md5 48463367ebce5dd43763ed327d76ccb2 and 3fe3652ebd5404a44395b707b16bcf71 match on both sides). If Design is no longer expected to provide assets, the placeholders need replacing before this comes out of draft — otherwise the label likely belongs back on the PR. Either is fine; just confirming the situation isn't accidental.

Outstanding content items (unchanged — file hasn't been edited since 21:55 UTC)

Restating the punch list from my prior pass since nothing has moved on the content side:

• H2 heading case — lines 42, 53, 109, 115 still Title Case (AGENTS.md requires sentence case for H2+). Fix this →
• First-mention links — lines 28 (AWS Secrets Manager, HashiCorp Vault, 1Password) and 119 (Pulumi CLI) are still unlinked. Targets all verified.
• CTA shortcode at the end — line 127 still closes with a generic summary; conventional ending for feature/integration posts is blog/cta-button.
• Vault .data.key convention — path: secret/data/stripe + .data.key at lines 87, 103, 107 still worth confirming or annotating as KV v2.
• More-tag placement (minor, judgment call); AI/hedging phrasing (soft).

Confirmed: still in good shape

• Diff scoped to the three intended files only.
• Social frontmatter paragraph formatting compliant on twitter/linkedin/bluesky.
• Author profile + avatar present.
• Code examples have language specifiers; ESC YAML cross-checks against content/docs/esc/integrations/dynamic-secrets/.
• Title 36 chars; meta_desc 137 chars (within 50–160).

Since this is now draft and the punch list is mechanical, want me to push the H2-case fixes, first-mention links, and CTA shortcode directly? Just confirm and I'll make the edits. (I'd leave the Vault .data decision to you since it depends on the engine setup you tested.)

Tip

Summary: New content-sprint blog post introducing how Pulumi ESC can compose secrets from AWS Secrets Manager, HashiCorp Vault, and 1Password into a single resolved environment; it parallels existing ESC posts under content/blog/. The kind of wrongness that would block a reader's success here is an incorrect YAML example (wrong provider keys/fields, wrong shortcode/CTA usage) or a broken internal link to ESC docs — the post is otherwise short and conceptual. Claim extraction (27 claims), claim verification (12 ✅ verified upstream; 12 🤷 unverifiable due to verifier HTTP 429 — manually re-verified against the local ESC provider docs; see triaged findings), frontmatter sweep, temporal sweep, code-examples structural/existence checks, and editorial-balance pass all ran.

Review confidence:

Dimension	Level	Notes
mechanics	HIGH
facts	HIGH	12 verifier verdicts were rate-limit errors; each was manually re-checked against the local ESC provider docs (vault-secrets, 1password-secrets, aws-secrets, imports, environmentVariables) and matches.
code correctness	HIGH	YAML examples match the documented fn::open::aws-login, fn::open::aws-secrets, fn::open::vault-login, fn::open::vault-secrets, and fn::open::1password-secrets schemas.

• L53 in content/blog/multi-source-secrets-with-pulumi-esc/index.md "In Pulumi ESC, environments are defined using YAML." → ✅ verified (evidence: The blog post at line 53 states: "In Pulumi ESC, you define environments using YAML." This is a direct match to the claim that "environments are defined using YAML."; source: repo:content/blog/multi-source-secrets-with-pulumi-esc/index.md)

The Inputs table states: "region — The AWS region to use…; source: repo:content/docs/esc/integrations/dynamic-secrets/aws-secrets.md)

📋 Triaged verifier findings

I double-checked these and realized they weren't real findings — click to expand

The verifier returned unverifiable (HTTP 429 rate-limit error) for the 12 claims below before any source fetch ran. I re-checked each one manually against the local ESC provider docs in this repository; all 12 match the documented behavior, so none of these warrant an ⚠️ buffer line for the author.

• [L77-80] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "The fn::open::vault-login function in Pulumi ESC accepts an address and jwt.role parameter for Vault JWT/OIDC authentication." — Mis-sourced (rate-limit error): matches the example block in content/docs/esc/integrations/dynamic-secrets/vault-secrets.md (L20–36), which uses fn::open::vault-login with address: and jwt: role:.

• [L92-98] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "The fn::open::1password-secrets function in Pulumi ESC accepts a login.serviceAccountToken and a get block with an ref parameter using the op:// URI." — Mis-sourced (rate-limit error): matches the Inputs / 1PasswordSecretsLogin / 1PasswordSecretsGet tables in content/docs/esc/integrations/dynamic-secrets/1password-secrets.md (L48–66).

• [L111] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "The fn::open::vault-login function authenticates ESC to Vault using the JWT/OIDC role configured in Vault." — Mis-sourced (rate-limit error): matches the example and the "Configuring OIDC" section in content/docs/esc/integrations/dynamic-secrets/vault-secrets.md.

• [L111] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "The fn::open::vault-secrets function uses the login session produced by fn::open::vault-login to read a specific secret path in Vault." — Mis-sourced (rate-limit error): matches content/docs/esc/integrations/dynamic-secrets/vault-secrets.md (the example wires login: ${vault.login} into fn::open::vault-secrets and reads paths via the read: map).

• [L111] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "The field: api_key setting in fn::open::vault-secrets selects the literal api_key field stored at the specified Vault path." — Mis-sourced (rate-limit error): matches the VaultSecretsRead table in content/docs/esc/integrations/dynamic-secrets/vault-secrets.md (L88–93): field is documented as "[Optional] - The field of the value to read."

• [L117] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "Pulumi ESC supports an imports: key that allows a child environment to compose a base environment and then override specific values." — Mis-sourced (rate-limit error): matches content/docs/esc/environments/imports.md (L30–32), which describes imports merging via JSON Merge Patch "with the current values overwriting the imported environment's values where keys are redefined."

• [L119] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "You can view the resolved secrets using the Pulumi CLI." — Mis-sourced (rate-limit error): pulumi env open <org>/<project>/<environment> is shown as a resolution-check command throughout the ESC provider docs (e.g. vault-secrets.md L43, aws-secrets.md L74, gcp-secrets.md L46, infisical-secrets.md L49); the linked /docs/install/ page exists in the repo.

• [L127] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "In Pulumi ESC, values defined in a child environment take precedence over imported values with the same path." — Mis-sourced (rate-limit error): matches content/docs/esc/environments/imports.md (L30–32, L669–725), which document JSON Merge Patch precedence and walk a worked example.

• [L129] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "{{< blog/cta-button 'Explore ESC dynamic secrets' '/docs/esc/integrations/dynamic-secrets/' >}}" — Mis-sourced (rate-limit error): the blog/cta-button shortcode exists at layouts/shortcodes/blog/cta-button.html; the destination /docs/esc/integrations/dynamic-secrets/ resolves to content/docs/esc/integrations/dynamic-secrets/_index.md.

• [L133-137] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "The command pulumi env open <org>/<project>/multi-source-env returns a single JSON object containing all the resolved values from a Pulumi ESC environment." — Mis-sourced (rate-limit error): the JSON-object output of pulumi env open is shown in content/docs/esc/integrations/dynamic-secrets/vault-secrets.md (L47–71) and in every other provider doc that documents the OIDC validation step.

• [L139] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "The pulumi env open command returns a single JSON object containing all the resolved values." — Mis-sourced (rate-limit error): duplicate of the L133-137 check above; same evidence.

• [L139] content/blog/multi-source-secrets-with-pulumi-esc/index.md — "The environmentVariables block in a Pulumi ESC environment exposes selected values to pulumi env run and shell-based tools." — Mis-sourced (rate-limit error): matches content/docs/esc/environments/syntax/reserved-properties/environment-variables.md (which documents environmentVariables as the property exported by esc run) and content/docs/deployments/deployments/permissions.md L73–76 (which documents pulumi env run invoking commands in the context of an ESC environment).
