Five finance calculators, one stale base price
Corrected 11 Jul 2026
- What we published
- Five Eldeco Echoes of Eden finance pages — the EMI calculator, the total-cost calculator, the NRI TDS explainer, the GST/input-credit explainer, and the tax-benefits (80C/80EE/24B) explainer — all correctly labelled the entry unit “₹1.44 Cr,” but several of the GST, TDS and EMI figures worked out underneath that label were still computed off the prior ₹1.39 Cr / ₹8,999-per-sq.ft base. The label had been updated when the BSP moved; the arithmetic underneath it hadn't.
- How long it was live
- About six days — from the BSP update on 5 Jul 2026 to the fix on 11 Jul.
- What caught it
- Our mirror-drift monitor, during a fact-reconciliation pass across the Eldeco EOE blog set specifically checking whether recent price-base changes had actually propagated into every derived figure, not just the labels.
- The fix & the new rule
- All five pages were recomputed against the canonical tier set (₹1.44 / 1.72 / 2.51 / 2.93 Cr). New rule: when a base input changes, every downstream computed figure gets recomputed and independently checked against its own formula before the page ships — updating the label is not the fix, it's the reminder that a fix is owed.

A rental-ROI worked example that didn't add up
Corrected 11 Jul 2026
- What we published
- A Yamuna Expressway rental-yield/ROI page ran a worked example for a 3 BHK+2T unit. When its BSP line was updated from ₹8,999 to ₹9,300 per sq.ft on 5 Jul, the “Base cost” line directly beneath it was left at the old ₹1.57 Cr figure — but ₹9,300 × 1,750 sq.ft actually comes to ₹1.63 Cr. The all-in total and both yield percentages built on top of that base were correspondingly wrong.
- How long it was live
- About six days — the same 5–11 Jul 2026 window as CL‑01, the same underlying failure caught in the same pass.
- What caught it
- Our mirror-drift monitor, in the same eldeco-side fact-reconciliation pass as CL‑01.
- The fix & the new rule
- Recomputed with every assumption stated on the page: base ₹1.63 Cr, all-in ~₹1.90 Cr, gross yield 3.2%, net yield ~2.5%, and a five-year exit value of +₹2.45 Cr on a stated, conservative 50% appreciation assumption. New rule: a worked example gets its own arithmetic re-derived from its stated inputs before publish — a number that can't be reproduced from the assumptions printed next to it doesn't ship.

Airport status flipped back to future tense
Corrected 10 Jul 2026
- What we published
- During a same-day batch pass syncing 13 blog pages to current facts, one FAQ heading on a comparison page got over-corrected: an already-accurate sentence — “Will Solitairian City appreciate now that Jewar Airport is open?” — was changed to an inaccurate future-tense version, “…when Jewar Airport opens?” — implying the airport wasn't operational yet, when it has been since 15 Jun 2026.
- How long it was live
- 35 minutes — the edit and its revert are both timestamped, about 7:16pm to 7:51pm on 10 Jul 2026.
- What caught it
- A ground-truth audit the same evening — cross-checking the airport's actual status against independent published sources (Business Standard, Business Today, Wikipedia) rather than against our own prior copy.
- The fix & the new rule
- The single sentence was reverted, and the underlying fact was locked into our internal operations reference rather than left as a page-specific note. New rule: infrastructure status — is the airport open, is a road built — is a publicly verifiable fact and gets checked against independent sources before any edit touches it, never batch-corrected on the assumption that "make it consistent with the other pages" is automatically the fix. Only unit inventory and availability stay founder-only judgment calls.

An invented “Studio” configuration
Corrected 10 Jul 2026
- What we published
- A “Studio” unit line — roughly 550 sq.ft super area, 330 sq.ft carpet, ₹9,300/sq.ft, ₹55–60 lakh all-in — sat in the unit-mix table, two FAQ answers, and the floor-plan copy on the Eldeco Echoes of Eden brochure page and its mirror twin, since both pages were first published. It contradicted the actual RERA-filed inventory, which lists five configurations: 2 BHK (sold out), 3 BHK+2T, 3 BHK+3T, 4 BHK Penthouse and 4 BHK Grand Penthouse. No Studio appears anywhere in that filing.
- How long it was live
- About five and a half weeks — from the page's original publish on 2 Jun 2026 to the fix on 10 Jul.
- What caught it
- A routine consolidation audit flagged it, report-only, on 9 Jul (“inventory unverified — founder to confirm”); the founder checked it directly against the RERA-filed configuration list the next day and confirmed no Studio exists.
- The fix & the new rule
- The Studio row, its FAQ mentions, and the floor-plan copy referencing it were removed from both mirror twins on 10 Jul. New rule: any unit configuration named in copy must trace to the RERA-filed inventory list, not to language carried over from an earlier draft that nobody re-checked against the filing.

Google's AI Overview echoed a self-label we'd already banned
Corrected 9 Jul 2026
- What we published
- Our own JSON-LD titles and llms.txt self-descriptions for one project site used a self-label that read as a dealer-run satellite site rather than an authoritative one — a specific word we've since banned outright (see the fix below). On 9 Jul 2026, Google's AI Overview summarised the site using that same self-label almost verbatim — vocabulary it had learned directly from our own structured data, not from an outside source.
- How long it was live
- We can't date the exact start — the phrasing had been part of our schema and llms.txt since these pages were first built. What we can date is when it surfaced publicly: 9 Jul 2026, quoted back at us in a Google AI Overview.
- What caught it
- A founder correction — Vidit read the AI Overview himself.
- The fix & the new rule
- The label was swept to zero the same day across all seven property repos; every self-reference was rewritten to “official website.” New rule: never describe any of our own sites, anywhere customer-facing — copy, meta, JSON-LD or llms.txt — as a dealer-run satellite of anything: not that banned word, and not softer variants like “channel-partner website” either, because AI engines quote self-descriptions back verbatim. The channel-partner relationship stays disclosed in the legal disclosure block, not in how a site names itself.
